    A tool changer for rotatable tool assemblies in punching machines has coaxial, upper and lower synchronously rotatable tool housings (1,2). These are parted along a plane through the rotational axis to form a stationary rotatable guide part (11,11') and a guide part (12,12') radially movable relative said axis. The respective parts (11,12 and 11',12') can be latched to each other for receiving and guiding coacting tool assemblies. Transfer means (20,21) transfer tool assemblies between a turret magazine (30,31) and the tool housings. The transfer means are coupled to the movable guide parts (12,12') of the housings. The coupling permits the housings to be rotated after the movable guide part with the aid of its transfer means has moved a tool to a working position in the tool housing and the guide parts of the housing are mutually latched. The tool changer enables very rapid, programmed tool changing and is particularly suitable for setting up multitool punch assemblies or so-called cassette-type tool assemblies (70,71) having a plurality of punch pins and dies which may be selected by rotation of the tool housings.

The coupling of the tool shank with the clamping head 29 is provided by means of a T-shaped groove 31. The rotation of the upper and lower tools during their reciprocating axial movement is prevented by the keys 32 and 33, respectively. The upper turret disk 1 contains a ring element 34 in the form of a plate associated with the bed 7 by means of a gear 35 and a bearing 36. Along the periphery of the element 34 are located the guides 37 with T-grooves 38. In the latter, the springs of the upper tools are held by springs 39. A similar groove 40 is made in the upper fixed part 8. This groove serves to move the tools from the upper housing 3 to the upper turret disk 1.
    The lower revolving disk 2 is installed in the lower part of the bed 7 coaxially with the revolving disk 1, the revolving disk 2 is connected with the bed 7 through the gear wheel 41 and the bearing 42. to receive matrices 6.
    The device is equipped with tools for removing tools from the tool cases. These means are made in the form of the upper 44 and lower 45 working cylinders installed outside the respective instrument cases diametrically opposed to the means of radial movement of the moving parts 9 and 12 of the buildings. The rods 46 and 47 of cylinders 44 and 45 serve as ejector tools when moving in the direction perpendicular to the junction plane of the moving and stationary parts of the bodies.
    The tool changer can be used to feed a multi-tool punching block or punch tool into a turret in the form of a plate 48, in which there are several punches 49 and 50, a mounting plate 51, a shank 52 connected by a threaded connection to the plate 48, and springs 53, placed in the slots 54, made in the mounting plate 51, the key 55, mounted on the shank 52, the matrix unit 56, fixed to it key 57. Such a multi-tool forging The first block is connected to the press bed 7 by means of a recess to the mounting plate 51 and the protrusion 52 entering it. The matrix block 56 is connected to the lower tool body 4 and the press bed 7 in the same way as described (Figures 4 and 5).
    The tool changer operates as follows.
    The upper 3 and lower 4 instrument cases are synchronously placed in the transfer position. In this position, the junction plane of the guiding parts 8 and 9, as well as 11 and 12 are located perpendicular to the plane running through the HG axis of the tool bodies and the B-axis axis of rotation of the revolving disks 1 and 2. The center lines of the working cylinders 14 and 15 and ejector cylinders 44 and 45 also lie in said plane. Then the cylinders 28 and the dogs 25 are released to release the elements 24. The working cylinders 14 and 15 are pulled into the right (according to the drawing) position D (shown in FIGS. 1 and 2 by a dash-dotted line). The grippers 18 and 19 (Figures 1 and 2) and the movable guide portions 9 and 12 of the inserts associated with them are retracted. In such a position, the turret disks 1 and 2 can rotate freely with the tool assemblies so that the tool assemblies extend between the respective tool bodies 3 and 4 and the movable guide portions 9 and 12 that are retracted.
    In this position, the turret disks 1 and 2 are rotated so that the required holder and tool are in position E.
    The operating cylinders 14 and 15 are activated, and the grippers 18 and 19, together with the movable parts 9 and 12, are moved to the tools in position,
    shown on the left, dragging tools into the working position J in the corresponding tool cases 3 and 4. When the upper tool shank moves, the upper tool holder 5 is guided into the T-slot groove 40 in the tool case 3 and engages with the corresponding T-slot 40 in clamping head 29, which tracks the angular position
    0 upper tool body 3. In a similar way, the lower tool or die holder 6 is fed to the lower tool body 4 in the working position. The correct direction
    The 5 movable guide portions 9 and 12 facilitate the keys 32 and 33. To further stabilize the direction during tool transfer between the pickup position in the revolving discs 1 and 2 and the working position in the tool housing, the arms 18 and 19 can be equipped with rails directed along fixed guides on the sides of the working cylinders 14 and 15.
    5The cylinders 28 of the cylinders are retracted and the pawls 25 fit into the grooves of the elements 24. The movable and fixed guide portions are fastened.
    In this position instrumental
    0 housings can be set to any desired angular position, while grippers 18 and 19 remain in a fixed position when engaged with the insertion portion 12 of the tool body through a T-shaped groove,
    5 so that the tool housing can take any desired angular position without interference from the gripper.
    In the embodiment of FIG. 3, the transfer means is retracted together with the collar 22 and the installation pins 23 after engaging the guide part 12 with the tool body and returns to the initial position D. The tool body can now rotate without interference.
    Since in position D, the grips are held between two instruments placed in the revolving disk, the grips and
    0, the movable guide 43 is made of a limited width, which is less than the distance between the tool holders in the revolving disk 1 on both sides of the tool being moved. By
    5 for a similar reason, at the bottom of the gripper 19 there is a protrusion that can pass between the guiding means 43 on the lower turret disk 2. Next comes the working phase, during which operations with the workpiece are performed.
    In this case, the tool bodies are synchronously rotated to install the tools 5 and b with the required orientation relative to the machine bed 7. The slider 30 is connected to the upper tool body 3 through the rotary clamping head 29 and transmits its movement to the upper tool regardless of its angular position.
    After the upper and lower tool cases are synchronously mounted to the tool change position, the turret disks 1 and 2 are mounted so that the tool can be taken in the receiving position E. The cylinders 28 are actuated to disengage the dogs 25.
    In the embodiment of Figures 1 and 2, the means 10 and 13 of radial movement are engaged with the corresponding grippers 18 and 19 of the movable guide parts 9 and 12. At the same time, the cylinders 44 and 45 are actuated so that the rods 46 and 47 moved forward to the corresponding upper and lower tool holders for: pressing them against the movable guides 9 and 12 in the receiving position to the corresponding revolving magazine. Thereafter, the means 10 and 13 of the radial movement are retracted to the initial position D. After cutting out the tool holder to the receiving position E in the tool magazine, after cutting the rods 46 and 47 return to the original position.
    In the embodiment of FIG. 3, the rod 17 of the cylinder 15 feeds the latch 21, the collar 22 and the studs 23 by the guide part 12. The pawl 25 is disengaged, after which the cylinder 15 can return the guide part 12. At the same time the cylinder 45 is pressed by the rod 47 - a body to the guide part 12 so that the holder returns to the receiving position E to the tool magazine. The cylinder 45 then returns to its original position, while the rod 47 also returns to its original position. The upper tool housing moves in the same way. The tool magazine is then rotated in order to place the next required tool in the replacement position, and then the loading cycle is repeated.
    It is advisable to carry out the listed movements for replacing a tool with program control using known electronic control methods.
    For changing the tool shown in FIGS. 4 and 5, the punches 49 and 50 have
    in the respective instrumental holders so that the guide groove of the mounting plate 51 faces the shank 52 (the directionality of the matrix
    block 56 is provided in a similar manner). As a result, due to the synchronous rotation of the upper 3 and lower 4 tool cases, the required punch 49, 50, etc. are placed in the working position.
    0 The proposed tool changer speeds up the change process and also increases the number of different tools installed in the turret punch press.
