    A plurality of expanding mandrels (43) are arranged around a central axis (A), on a turret (30) which can be driven in rotation about the central axis (A). They are each composed essentially of a supporting body (44), which is secured on the turret (30) and defines an axis (B) of the expanding mandrel, a plurality of segment rods (52), which are arranged around the axis (B) of the expanding mandrel and are guided in radially adjustable fashion on the supporting body (44), and a wedge (70), which can be displaced along the axis (B) of the expanding mandrel in order to spread apart the segment rods (52). The wedges (70) can be displaced in succession by a common actuating member during one revolution of the turret (30). The actuating member is a central cam body (18), on which each of the wedges (70) is supported at least during a part of each revolution of the turret (30) which corresponds to the spacing between two adjacent expanding mandrels (52). …<IMAGE>…

    专利说明:

    The invention relates to a can manufacturing technology, in particular, to devices for changing the cross sectional shape of the shells.
    The aim of the invention is to improve the quality of processing while maintaining performance.
     FIG. 1 shows the device, a general view; figure 2 - expandable mandrel; Fig, 3 - device, vertical section; in fig. 4 - expanding head, longitudinal section; in fig. 5 - sections AA, BB, VB and GG in FIG. four; in fig. 6 is a section DD-D in FIG. four; FIG. 7 is a view E of FIG. one.
    The device for shaping the shells contains a drive 1 formed, for example, by an electric motor, a continuously variable transmission and a step-by-step switching mechanism and a driving central shaft 2 arranged horizontally and mounted by its free ends in a rack 3.
    A shaft 5 is mounted on shaft 2 by means of a pair of rolling bearings 4, with both ends of which are mounted on rolling bearings 6 of housing 7 and 8. The housing 7, located on the drive side 1, is rigidly connected to the end wall 9 of the turret and connected by means of a key 10 with shaft 2 to ensure joint rotation. The housing 8 is rigidly connected to the end wall 11 of the turret. The walls 9 and 11 are fixedly interconnected by means of a frame 12, having the shape of an octahedral prism.
    At the cam 5 remote from the actuator 1, an adjusting mechanism for its fixation is fixed in the form of a lever 13, having at the remote end of the shaft 2 an arc-shaped groove 14, through which a screw 15 attached to a rack 3 passes. which can be selected within the length of the groove 14. For example, the cam 5 can be set so that its largest radius faces vertically upwards. Usually the lever 13 is connected to a drive (not shown), which tells it
    tact reciprocating movement.
    On each face of the frame 12, an expandable mandrel 16 is installed, the axis of which intersects. central axis of shaft 2 at right angles.
    Each razchina mandrel 16 is made in the form of a composite support element 17 with a flange 18, rigidly attached to the corresponding face of the frame 12 Upper
    part 1.9 of the element 17 is fixedly connected to the flange 18 by means of a pair of prismatic supports 20. Between the supports 20 there are free places in which
    two pairs of segment rods 21.
    Each segment rod 21 is in contact with the upper part 19 by means of the guide 22 with the rolling elements. Each guide 22 consists of a pair of radial grooves 23, one of which is made respectively in the flange 18 and the upper part 19, and the other on the adjacent end of the corresponding segment rod 21, as well as from two cylindrical rolling bodies 24 and
    separator 25. The radial grooves 23 are made prismatic and have two sides fixed to each other at a right angle, along one of which the corresponding rolling bodies 24 run in,
    In each segment rod 21, near its ends, one radial stepped hole 26 is made. In these holes, there are screws 27 fixed to the flange 18 and the upper part 19 and
    spring 28 compression. Spring 28 squeeze the head between the screw head 27 and the step made in the corresponding stepped hole so that it tends to radially move the segmented
    rod 21 to the center of the mandrel. The inner surfaces 29 of the segmented rods 21 are inclined, converging towards the free end of the expanding mandrel 16.
    To carry out the unclamping of the segment, the rods 21 in the middle of each unclamping
    mandrel 16 installed wedge 30 having
    inclined surfaces 31 parallel
    inclined surfaces 29 segmented
    w chip Between inclined surfaces
    29 and 31, a guide 32 is installed, formed by the cylindrical bodies of quality 33, a. also separator 34. The movement of each separator 34 in the direction of the free end of the corresponding expanding mandrel 16 is limited to the stop 3.5, which can be made in the form of a bolt screwed into the corresponding inclined surface 29.
    A guide tube 36 is fixed in the flange 1.8 of each mandrel, and the flange 37 is pressed into the office. Each wedge 30 has a shank 38 passing through the corresponding guide tube 36 in the ball guides 39. At the free end of the shank 38 a roller 41 is installed by means of a fork 40. whose axis is parallel to the axis of the shaft 2. Between the fork 40 and the flange 37 a pair of springs 42 is installed, pressing the fork 40 with the roller 41 to the cam 5. At the same time, a wedge 30 rigidly connected to the fork 40 allows move segmented rods 21, g neem internally position as a result of exposure to the compression springs 28.
    At each revolution of the turret, each ram mandrel 16 reaches a position in which its axis is coaxial with the horizontal feed axis of the shells 43. Along this axis, a pair of beams 44 are fixed to the corresponding unclamp mandrel 16, parallel to the axis which move the expansion mandrels 16 and on which are mounted with the possibility of movement. grippers 45 for transporting the shell 43. The grippers 45 are provided, for example, with magnets or vacuum suction cups in order to grip the shell 43 and feed it to an expandable mandrel 16 located between the beams 44,
    The shell 43 is pulled over the expanding mandrel 16 during a brief stop of the turret. At the same time, the lever 13 is slightly rotated in accordance with the stroke of moving the grippers 45. As a result, the shell 43 is clamped by an expanding mandrel 16 and the grippers 45 can be returned to its original position to grip the next shell 43.
    Each shell 43, mounted on one of the expanding mandrels 16, is gradually deformed with further revolving of the turret due to the fact that the segment rods 21 are moved apart. Then
    the segmented rods 21 are returned to their original position, so that the deformed shell 43 can be removed from the expanding mandrel 16. In the illustrated example of this embodiment, this shell is removed after the revolving head is rotated 270 °. Warped shells are removed vertically down.
