    Technical field
    [0001] The general field of technology is metallurgy and assembly of sheet metal components. Background
    [0002] Metal forming and assembly of thin sheet metal components in high volume production is one of the pillars in the automotive and other fields. An example is the manufacture and installation of automotive sheet metal doors and body panels, where at least two layers of steel plates are joined to form an internal and external panel, with space between them for other components, such as windows and locks and lock mounts.
    [0003] These sealing panels often require along the peripheral edges of the panels to prevent rain, snow and wind from entering the vehicle's interior compartment. In order to properly seal these panels, it is highly desirable to have a precision sealing surface that is free from abrupt variations in the metal sheet and the elimination of sharp edges of the cut stamped panels. In addition, it is highly desirable, from an aesthetic, visual point of view or to have a clean finished panel border and continue as the doors and body panels are the most visible part on a vehicle.
    [0004] Previous manufacturing and assembly processes employed "sheathing" assembly operations, which generally roll or fold the edge of the outer panel around the edge of the inner panel and crush the outer edge of the panel back inside as the sheath. sewing on ordinary everyday clothing pants. This produces a relatively thin edge, which is useful for applying an elastomeric seal and / or applying aesthetic molds or other treatments that can be applied to the finished panel.
    [0005] Previous sheath devices and processes have suffered from numerous disadvantages in the devices and processes used. Examples of these difficulties and disadvantages include keeping the roller pressing down on the finished edge in continuous contact with the contoured sheet metal, maintaining the necessary pressure on the sheet metal joint to form the desired edge. Conventional sheathing devices and processes were also unable to form or press down the metal edge on an exposed outer surface and could not be used to reach, for example, an inner and hidden edge or exert a force in a direction of traction, for example on the inner surface of a door window channel. Previous devices have attempted to solve this problem with bidirectional sheathing devices, but these devices continue to have the disadvantage of complex mechanisms and processes that lack the precision and durability required for a high volume production environment.
    [0006] Previous sheathing devices also suffered from the disadvantage of having to employ structures and physical space in the vicinity of the component to be sheathed / worked in order to compress or preload any internal polarization mechanism in order to have the desired strength applied and has the desired stroke in the head to accommodate variations in the process. Earlier devices suffered from the roll or corner shapes that wish to increase or raise in initial contact of the metal due to insufficient preload or the resistance force provided by the drive mechanism.
    [0007] Therefore, there is a need for a sheathed head device that can be easily integrated into high volume production environments that resolve or ameliorate these and other difficulties and disadvantages experienced by previous projects. Brief summary
    [0008] The present invention includes several examples of devices for solving or ameliorating the above disadvantages in previous projects.
    [0009] In an example of the invention, a roller head of the hemming device includes double polarized members aligned along the axis of the head housed in a preload cartridge installed in the cylinder head body. The inclined members are compressed and preloaded, once installed and fixed on the cylinder head body, they provide the necessary resistance to the initial contact of the roller or corner shapes for the part to be a sheath to substantially eliminate the condition of the corner rollers or ways of lifting distance from the hem.
    [00010] In an example of the roller head, a quick-change sheath wheel mechanism is used. The quick-change mechanism allows the sheave wheels to be quickly and easily removed from the roller head, either manually or automatically for replacement, cleaning or interchange with other wheels or workpiece builders according to the order.
    [00011] In another example, a plurality of different corner forming tools are positioned on the roller head to increase the ability of the head to bend or form different corners of the size component during the sheath process.
    [00012] Examples of processes for hemming and using the hemming device of the invention are also disclosed. Brief description of the drawings

    [00024] Examples of a roller head device 10 of the invention usable in a sheath assembly process are shown in Figures 1-10. Referring to Figures 1, for example, the sheath roller head 10 used in an exemplary application with an autonomous industrial multi-axis 12, which has a handle 16 capable of moving and articulating the head 10 in three-dimensional space is shown. In an application example, robot 12 would be connected electronically to a controller (not shown), which is pre-programmed through hardware, software and memory to move and articulate the head 10 and the selected sheave wheel along a pre path -determined trips to form a desired component through a sheath type process described below. The sheathing head 10 can be used with other industrial robot devices to meet the particular order or specification.
    [00025] With reference to Figures 2-6, an example of a roller head 10 is shown. In the example, head 10 includes a universal circular mounting plate 14 with a plurality of mounting openings suitable for use with various common industrial robot terminal operators to quickly and easily connect the roller head 10 to many types of industrial robots 12. The mounting plate 14 is preferably made of steel, although other materials known to those skilled in the art can be used. Other plates, supports, end effectors, or other wiring diagrams (not shown) can be used.
    [00026] The head 10 further includes a body 20, a bearing retainer 26, a first hemming wheel 30, a second hemming wheel 36 and a plurality of corner-shaped tools 40. In a preferred example, such as best seen in Figures 5 and 6, the body 20 includes a cylindrical housing 50 which has an outer surface 52, a first end 54 and a second end 60 separated along a longitudinal axis 62. The structure 50 further includes two grooves diametrically opposed wrenches 66 that provide openings through the side walls of the housing, which define an interior of the cavity 70 described below. The housing is preferably made of steel, but other materials, for example, aluminum, can be used as is known in the art.
    [00027] As best seen in Figure 3, the head 10 includes an axis 80. In a preferred example, the axis 80 includes a cylindrical upper part 84 and an integral portion an elongated lower element 90 positioned concentric within the housing 50 in the inner cavity 70 along the longitudinal axis 62. The upper portion 84 coordinates and is connected to the mounting plate 14 by means of mechanical fasteners or other connecting devices.
    [00028] The lower portion of the shaft 90 includes an outer surface 92, a first end 94 that joins the upper portion 84 and a second end 98 that extends downwardly to the bearing retainer 26. The outer surface 92 defines a cavity interior 100 extending along axis 62. The lower portion 90 further includes, by means of main grooves 102 aligned with key grooves 66 in the housing which is in communication with the interior cavity 100. The axis 80 is, in preferably made of steel, although other materials, for example aluminum, which are known to those skilled in the art can be used.
    [00029] As best seen in Figures 3 and 4, the head 10 includes two cylindrical bushings 106 by pressing on the outer surface 92 of the shaft 80 separated from each other along the shaft 62, as is generally shown. The bushings 106 are positioned in the inner housing of the cavity 70 radially between the outer surface of the shaft 92 and an inner surface of the housing 50 for contacting and guiding the housing by movement with respect to the shaft, as further described below. Bushings 106 are made from a low friction coefficient,
    [00030] Resistant to wear of the material, such as bronze with a low friction coating, for example RULON, although other materials known to those skilled in the art can be used. Although two bushings 106 are shown, fewer or more bushings can be used, as well as in different locations and orientations to suit the specific application and characteristics.
    [00031] As best seen in Figures 2 and 3, the exemplary head 10 includes a pair of preload spring elements 110, respectively, positioned at the first 94 and second 98 ends of the lower portion of shaft 90. Each member of preload includes a first portion 114, a second portion 116 and a seat cavity 118. The first portion 114 is positioned in a relief or cylindrical recess in the upper portion 84, so as not to interfere with the mounting plate 14 and the second portion 116 extends downwardly along axis 62 into the inner cavity of axis 100, as best seen in Figure 3. The first portion 114 is connected to the upper portion 84 by means of mechanical fasteners or by other appropriate connection methods . The second spring preloader 110 is positioned at the second end 98 of the lower portion of the shaft 90 and is selectively attached to the lower portion 90 in a similar or equivalent manner, as effectively described below of the inner closure of the shaft of the cavity 100.
    [00032] As best seen in Figures 2, 3 and 5, the head 10 includes a polarization preload cartridge 120, which is positioned inside the inner cavity of the 100th axis generally shown. In the example shown, the preload cartridge 120 includes a cylindrically shaped spring retainer 126 having an outer surface 130 and a portion of the extender 132 that extends radially outwardly from axis 62 towards the inner surface of the axis as it is best seen in Figure 5. Extender 132 is positioned and oriented to be aligned with the main bands 66 and 102 on the housing and axle, respectively. Retainer 126 includes a first cylindrical seat cavity or hole 140 extending downwardly along axis 62 and a second cylindrical seat cavity or hole 146 extending upwardly towards the first seat. The cavity or holes 140 and 146 are separated by a stop 148 which is integrated with the retainer so that the holes do not communicate.
    [00033] The preload cartridge 120 further includes a first tilt element 150 and a second biasing member 156 positioned respectively in the first seat of the cavity 140 and the second cavity of the seat 146 along the axis 62, as is usually shown. In the example, the bias members 150 and 156 are in the form of industrial helical compression springs of selected spring rates suitable for the particular application. Suitable examples of such springs are manufactured by Danly. In one example, a suitable spring compression includes a diameter of about 25 millimeters (mm) and a length of about 51 millimeters. In one example, the first 140 and second 146 cavity seats are approximately 26 millimeters in diameter and 35 millimeters deep. The opposite ends of the respective springs engage the respective seat cavities 118 in the opposite spring-loaded members 110, as generally illustrated. In a preferred example, the length of the first and second bias members, fitted to the spring retainer 126 and the preload members of the spring 110, slightly exceed the length of the inner cavity 100 of the shaft. It is understood that different diameters, lengths and the relations of spring bias members can be used, as well as different sizes and depths of cavity seats. It is further understood that other devices for polarizing members 150 and 160, including pneumatics, hydraulics, elastomers and other devices and materials can be used.
    [00034] When installing the preload cartridge 120 into the body 20, the inclined members 150 and 156 are installed in the spring retainer 126 and the cartridge is inserted into the inner cavity 100 of the shaft. To place the preload cartridge 120, the lower spring preload element 110 is installed at the second end 98 of the shaft. In order to accommodate and secure the preload spring element 110 and encapsulate the preload cartridge 120, p the first and second bias members are preferably required to be compressed by a predetermined amount to apply a preload force on the first and second bias members 150 and 156. In one example, the combined preload compression of the first and second bias members is 3-4 millimeters. load or linear compaction distances can be used to suit the particular application. In an alternative example, it can be preload or forced compression.
    [00035] As best seen in Figures 5 and 6, in a preferred example, the roller head 10 includes two diametrically opposed housing retainers 160. Each retainer 160 includes openings 164 and a key 168 that extends radially inward as see better in Figure 5. As best seen in Figure 6, each retainer 160 is positioned in a respective key groove 66 in housing 50, so that key 168 extends through the main grooves 102 on the shaft and the seat for inside the key groove 134 aligned on the spring retainer 126 as can be seen better in Figure 5. By fixing the housing retainers 160 by means of mechanical fasteners to the housing 50, the concentrically oriented housing 50 can move reciprocally along the axis 62 relative to axis 80 and robot 12, since the resistive force of the first 150 and second 156 bias members is exceeded.
    [00036] With respect to figures 3, 4 and 5, the head 10 includes a bearing retainer 26. The bearing retainer 26 includes a top portion 186 that has a radial cavity 190 for abutting the reception of the second end of the housing 60 , as best seen in Figure 5. Bearing retainer 26 is rigidly attached to housing 50, so that the bearing retainer moves reciprocally along axis 62 along with housing 50 as generically described above.
    [00037] As best seen in Figures 2 and 5, in the example head 10, bearing retainer 26 includes a hollow housing for encapsulating a pair of sealed bearings 204 spaced along a axis of rotation 212. Bearings 204 they can be spherical, tapered or other bearings known to those skilled in the art. An axle 210 has a first end 214 and a second end 216, is inserted through and coupled with bearings 204 preventing relative rotational movement between the axis and the bearings as generally illustrated. Spindle 210 includes a threaded portion (not shown) placed towards the first end 214 and a radially extending stop 218 adjacent to the second end 216, as generally illustrated. As best seen in Figure 5, a nut 224 is threadably engaged with the threaded portion of spindle 210 so that nut 224 and stop 218 are brought into contact with the bearings, preloading the bearings and preventing the linear movement of axis 210 along axis 212 while allowing free rotation of the axis about axis 212.
    [00038] In a preferred example, head 10 further includes a seal cap 220 connected to the seal wrapped with bearing retainer 26 and spindle 210 to prevent unwanted sealer / adhesive, dirt and debris from entering bearing retainer 26. As shown, the sealing cap 220 can be positioned between the nut 224 and the bearing spacer 226. Other configurations and orientations of the seal cap 220 can be used.
    [00039] In a preferred example, head 10 includes a sheath wheel 230 quick release device at each end of shaft 210. Each release device 230 includes one or more retractable bearings 236 (two shown) positioned in containers on the spindle . Device 230 includes a release mechanism 250 in engagement with retractable bearings to selectively retract radially moving bearings selected from a plunger 252. The linear motion of plunger 252 radially retracts bearings 236. By releasing pressure applied to plunger 252, springs or other polarizing devices (not shown) polarize the bearings 236 back to the normal or standard position. In the example shown, the wheel axle 220 and / or sheaths includes an orifice 256 in communication with the plunger to manually access and activate the respective plunger. Scabbard wheels 30 and 36 each include through the wheel mounting hole at the end of the selected axle. Each wheel bore includes coordinating receptacles (not shown) to engage the reception of retractable bearings 236 to lock the wheel onto the axle preventing relative axial movement between the wheel and the axle. Other quick release devices 230 and release devices 250 known to those skilled in the art can be used.
    [00040] In the preferred example shown in Figure 6, the head 10 further includes a plurality of corner shapes or corner forming tools 40 positioned and rigidly connected to the head 10. corner shape 40 are useful for bending and forming rounded corners of pre-sheath components or forcibly final sheath operations during the sheath process. In a preferred example, each corner shape 40 includes a different radius to accommodate a different radius over the part, or parts, to be surrounded or worked. As several illustrated corner shapes 40 can be mounted on the support 264 connected to the upper portion of the axis 84, as best seen in Figures 4 and 6. In this position, the corner shapes are advantageously rigidly connected to the axis 80 and the robot 12 to avoid the relative movement between the corner shapes and the robot 12. This also positions the corner shapes 40 closer to the mounting plate 14 for reducing the strength of arms and torques created by pressure on the corner shapes when in use.
    [00041] In the example, as best illustrated in Figures 6 and 7, a cover 270 including several corner shapes 40 radially separated around the axis 62 is rigidly connected to the bottom of the retaining bearing 26 via one or more clamping parts 274 with a preferred aspect, ten (10) different corner shapes 40 are used on each head 10, although more or less numbers can be used or multiples of the same corner shape can be used as is known to those skilled in the art. Another position of location and orientation of the corner shape 40 with respect to the head 10 can be used as is known to those skilled in the art.
    [00042] As best seen in Figures 1 and 2, the specimen sheave rollers 30 and 36 are shown. In the example, the first wheel 30 is preferably about 90 millimeters (mm) in diameter and the second wheel 36 is about 14 millimeters (mm) in diameter. It is understood that different wheel diameters, orientations and shapes can be used to suit the particular application. For example, the second wheel 36 can take a tapered or tapered shape or construction versus a cylindrical shape, as shown. Wheels 30 and 36 are preferably made from hardened steel tools that exhibit good wear and resistance characteristics. Other materials known to those skilled in the art can be used.
    [00043] Referring to Figure 8, an example of a 280 gauge is used to measure or track the stroke and / or force of wheels 30 and 36 in a production operation. Exemplary caliber 280 includes graduation marks or scale 286 positioned on the outer surface housing 52, preferably calibrated to the desired measure to be made, for example, strokes, in millimeters of force in pounds. The caliber 280 further includes a gauge or needle 290 mounted on the underside of the upper portion of shaft 84, as is generally shown. Indicator 290 is positioned close to scale 286 to easily indicate or mark the current reading, along with scale 286. One or more meters 280 can be used over the circumference of the housing 50 or located in other areas to reflect the relative positions between 50 and the housing axis 80. Although shown as a mechanical indicator, it is contemplated that the meter 280 can take the form of an electronic meter for electrical measurement and / or the monitoring of the relative position as described above. An electronic meter can be placed in electronic communication with a visual reading or send data signals to a remote station where the data can be monitored and stored for historical data over a period of change, or time. Other gauges known to those skilled in the art can be used.
    [00044] In an exemplary application or operation, for example edge sheath around an automotive door panel, the roller head 10 would be mounted for an industrial robot 12, by the mounting plate 14 using conventional or other fastening elements means. In the case of use of the roller head 10 there is a pressure application, in other words, a compression force applied from the robot to the selected wheel 30 or 36, the robot exerts an axial force, mainly along the axis 62 with the shaft 80 through the upper portion of the shaft 84 and preloader spring 110 in contact with the first bias member 150. The force is transmitted through the preloader spring 110 further compressing the first bias member 150 that it applies a downward force on the stop 148, the retaining spring 126 and the connected housing retainers 160. The extenders 132 transfer the downward radial force to the outside by means of housing retainers 160 down through the compartment 50, and having the retainer 2 6 for the sheave wheel selected 30 or 36 for the sheath assembly on the component to be formed (not shown). As explained, there is preferably a preload in the preload cartridge 120, for example, in an amount of about 3-4 millimeters. During a sheathing operation, a force is applied to compress the first bias member 150 by about 5 millimeters. The clearance between the upper end of the spring retainer and the upper part of the shaft 84 provides about 12 millimeters of maximum travel. Other clearances and stroke lengths known to those skilled in the art may be used.
    [00045] In an alternative pull type application where the second wheel 36 is positioned in, for example, an interior channel of a door window opening, the robot, instead, the pulling wheel 36 in one direction in the direction of mounting plate 14. In this example, shaft 80 and attached mounting plate 14 would be axially stretched or forced in a direction generally along axis 62 away from wheel 36. Axial force would be transferred through bearing retainer 26 through from housing 50, through retaining housing 160 to retaining spring 126 and through shaft 80. The movement resistance of wheel 36 in the direction of shaft 62 is absorbed through retaining spring 126 and stop 148 and compresses the second bias member 156. The clearance between the second end of the shaft 98 and the lower inner surface of the casing 50 is approximately 12 millimeters, providing 12 millimeters of maximum travel. The current design is useful in both compression (push) and tension (pull) operations when used in a sheath operation.
    [00046] Referring to Figure 9, an example process 300 for using head 10 is schematically illustrated. In example step 310, head 10 is assembled with a selected preload cartridge having selected bias members suitable for the sheath or forming operation. The preload cartridge is mounted and fixed on the axis of the cavity 100 and the creation of a preload compressed in the polarization elements, as described above in step 320. The housing 50 is installed concentric around the axis 80 and it is attached to the spring retainer 126 through housing 160 allowing the retainer relative axial movement between shaft 80 and housing 50 against the preload force in the preload cartridge 120.
    [00047] The bearing retainer is attached to housing 50 and the sheathing wheel or wheels are selected for the application. In step 330, the sheave wheels are connected to the appropriate end of the shaft through actuation and wrapping of the quick connection mechanism 230 to complete the assembly of the head 10.
    [00048] In step 340, the head 10 is assembled with a robot or other device for applying the articulation force in step 310. The robot is connected to a programmable travel preprogrammed travel controller.
    [00049] In step 350, the sheath roll is positioned along the programmed path of the trip until the selected wheel is placed in forced contact with the component to be surrounded or worked. Due to the preload in the preload cartridge, the forced contact of the sheath head wheel 10 onto the workpiece does not require additional axial movement to compress the spring or a suitable compression axial tilt element to accommodate variations in the the sheathed wheel path in order to maintain an adequate force to work the material unlike previous designs. The preload or step condition substantially eliminates any upward lift or tendency to raise the sheave wheel due to the higher resistance force of the material to its release point. The preload prevents this condition and allows the sheathing roller to pass directly to the ideal position in relation to the workpiece to initiate the rolling portion of the sheath process.
    [00050] In an alternative step 345, one of the plurality of corner shapes 40 are used to first force or work a rounded corner on the part. The same preload condition is also an advantage in the form of a corner to substantially prevent or eliminate the accumulation or lifting of the corner portion in forced contact with the workpiece. Another advantage of having a plurality of different corner shapes in the head 10 is that several different radii in a component can be formed by more efficient processing to achieve the hemming roll portion of the hemming process.
    [00051] In an alternative step 325, one or more of the sheave wheels are removed and replaced by the quick connect device 230. The release device 250 is accessed and operated to retract the bearings that allow easy removal of the wheel and replacement with the same or an alternative wheel. In one example, the quick connect release device 250 and plunger 252 are driven by an automated robot or other mechanism to disengage the device so that the wheel can be removed. In an alternative example, the release device 250 is accessed and manually operated by an operator. The quick-connect mechanism 230 is particularly useful when the roller head 10 is placed in an assembly cell along an assembly line where there are numerous constructions or modifications of the vehicle along involving the change of sheave wheels to accommodate different components and geometries to be formed.
    [00052] Referring to Figure 10, an example method for sheathing a 400 pulse or sheathing operation is illustrated. In the example, in a first stage 420, a preload is applied to a first 150 and a second 156 tilting element on an axis 80, of a sheathing head 10.
    [00053] In step 440, a molding element, for example a sheathing wheel 30 or 36, or a corner shape 40, is connected to housing 50, which allows relative movement between the forming element and the axis 80. In the example described above, the forming member can be connected to a bearing retainer 26 by means of a quick connection or release of the device 230 or other ways described above.
    [00054] In step 460, the molding element, for example a sheathing wheel 230 for outer joints is positioned to abruptly wrap the joint with the workpiece, wherein one of the first or second preload bias members 150 or 156 serve to help keep the wheel surrounding it in contact with the workpiece during the sheathing process or wheel travel path. As disclosed above, the process is useful in forming operations on the outer or inner edge or mixed applications.
    [00055] The additional or alternative steps, and the execution of alternative orders, can be used as is known to those skilled in the art.
    [00056] Although the invention has been described in connection with what is presently considered the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiments, but, on the contrary, it is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims, the scope of which is to be given the broadest interpretation, so as to cover all such modifications and equivalent structures, as permitted by law.
