The invention relates to the processing of metals by pressure and can be used in the automation of sheet metal forming, in particular for transferring workpieces between the positions of multi-position automatic presses.

The purpose of the invention is to expand the technological capabilities of the device.

FIG. 1 shows the proposed device, a plan view} in FIG. 2, a section A-A in FIG. one; in fig. 3 is a view B in FIG. one.

The clamshell feeder includes a housing 1 in which shaft 2 is mounted with bevel gear 3 and shaft 4 with a bevel wheel 5 and carrier 6. On a water 6 on the axis 7, an 8 o-ring is mounted, a U-roller, 11 and 12 gears are mounted on the 9-axis 9 earrings and slider 13. In addition, a closed copying groove 14 in the form of a rectangle with twisted corners is made in the copus 1, which is a path for the roller 10, a fixed toothed guide 15 is installed, similar in shape to a closed copy groove 14, grooves 16 are made, fixed guides 17 and mounted kr the brackets 18 and 19. In the slots 16, gear racks 20 are placed, in brackets 18 and 19, holes 21 are made 21. Gears 22 with gears 23 and rails 24 are mounted on brackets 18. Gears 22 are connected to the latter by shaft 26. On the toothed racks 20, the teeth are made on two sides, in the middle of the rail 20, the teeth are made on the vertical wall, and at the end of the rail 20 on the upper horizontal wall. The middle part of the rail 20 alternately engages with gear 12, and the ends on which the teeth are made on the upper horizontal wall enter gears 22 and engage gear 23. At the opposite ends of the rails 20, the legs 27 are reinforced, bearing paws 28 on themselves. The claws 29 and 30 are mounted on the paws 25 and 28. Rolling pins 31 are mounted in the holes 21 of the brackets 18 and 19, carrying the cross bar 32. In the groove 33 of the cross bar 32 includes a slider 13. The clamshell 29 and 30 are equipped with

spikes 34, which rhod t in the grooves of ZB traverse 32.

The device works as follows.

From the press crank mechanism, or another source, the movement is transmitted to the shaft 2 and through the bevel gear 3 and the bevel gear 5 to the shaft 4, from which the carrier 6 with a link 8 starts moving. The latter, through axis 9, causes roller 10 to run in a closed copier groove 14 and gear 11 rolls along a fixed, closed toothed guide 15. Due to the fact that gear 12 is made in the same block with gear 11, the revolutions of both gears when gear 11 is run along the fixed gear guide 15 are the same, as well as gear 12 carried Only more than gear 11, then during running it moves the rack 20 through the groove 16, and in one revolution of the gear 11 of the gear rack the rail 20 moves by a number of teeth equal to the difference in the numbers of teeth of gears 12 and 11. By moving the rack 20 rotates with its end gear 23 which, in turn, moves the rail 24 by the amount of movement of the gear rail 20 in the opposite direction, and therefore the grab bar 29 mounted on the leg 25 mounted on the rail 24 also moves.

The clamshell 30, mounted on the legs 28 of the uprights 27 on the second ends of the gear racks 20, moves towards the clamshell 29, and the grippers (not shown) mounted on the rails clamp the workpiece. When the gear 11 moves in the stationary-closed toothed guide 15 perpendicular to the gear racks 20, the slider 13 moves the yoke 32, which, in turn, acts on the spikes 34, informs the longitudinal movement of the clamshell 29 and 30 (i.e. transfer of products from position to position).

The length of the middle cut part of the toothed racks 20 depends on the minimum size of the punch opening, which allows the release of parts to transfer them to the next position.
