Abstract

This invention relates to the cold working of metals by pressure and can be used to move workpieces between work positions of a multi-position press. The purpose of the invention is to increase the reliability of work. The workpieces are moved between the working positions with the grapple rulers. Grab rulers are movably mounted on the sliders. The sliders are mounted on carriages with the ability to move perpendicular to the axis of movement of the blanks. Carriages are installed on the frame with the possibility of lifting. The clamshell rulers are driven in the longitudinal direction from the mechanism of the longitudinal movement, and in the vertical and transverse directions from the mechanism of the vertical and lateral movement. Mechanisms are associated with the drive. The mechanism for lifting and transverse movement contains longitudinal shafts that support the driving gears and the carrier, the driving gears mounted in the carriages, the gear racks mounted on the half wheels and interacting with the driven gears. On the bed fixed copiers interacting with the sliders. The longitudinal movement mechanism contains traction gear racks that support pivot arms that are articulated by means of t g with a clamshell. The drive contains coaxially mounted on the bed driven and drive shafts. On the driven and driving shafts, the body is freely mounted and bevel gears are fixed. The device is quickly adjusted and adjusted in all respects. 5 il. S cl

The invention of cold pressurized metalworking can be directly used to move piles between working positions of a multi-chinone press.

The purpose of the invention poveipiii reliability.

FIG. shows a grab feeder; in fig. 2 is a view A of FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows section B --- B in FIG. 2; in fig. 5 - installation of a grease {1feer feeder in-line for one piece fitting.

The gripper feeding device contains a bed 1. installed at the press 2 or at a row of presses 3 (lines), clamshell 4, located symmetrically with respect to the axis of movement of the workpieces (not shown), sliders 5, installed in the directions 6 symmetrically with respect to the axis of movement of the blanks and perpendicular to the axis of movement of the blanks.

On the sliders 5, a stand 7 is fixed, carrying guides 8 for moving the clamshell (1eke 4 in the longitudinal direction, i.e. in the direction. Parallel to the axis of the workpiece. The direction B is fixed on the carriage 9 mounted on the frame I With moving vertically along column 10.

On the sliders 5, the gear racks 11 which engage with the driven gears 12 are fixed or made integral with them. The latter are fixed in the carriage 9 by the axis 13. In the frame I, the shafts 14 are mounted parallel to the axis of movement of the blanks. On the shafts 14, the driving gear, gear 15 and carrier 16, bearing axes 17 are fixed. On the latter, intermediate gears 18 are mounted, the entrance shims with gears 12 and 15. Axes 13 and 17 are connected to each other by means of traces 19. On the shafts 14 there are mounted bevel gears 20 which engage with the conical shchesthern 21 mounted on the yala 22 carrying the gear 23. The shaft 22 is mounted in the bed 1.

In the base 1, the sliding toothed racks 24 are movably mounted, carrying the pivoting levers 25, pivotally connected through the connecting rods 26 to the gripper bars 4.

Gear rails 24 are mounted in guides 27 fixed in bed 1. Copiers 28 are mounted on the latter, and stop 29 is mounted on carriage 15. Gear rails 24 are driven from gears 30 fixed on nor- and bus 31 The latter is mounted on a drive 32 and a driven 33 shaft, which are aligned and mounted in antiquity on bearings 34. ha driven shaft 33

 a gear 35 is mounted, the inlet and. engagement with the center of the horn 23.

Bevel gears 36 are mounted on shafts 32 and 33, and bevel gears 37 are mounted in housing 31. Each of gears 37 meshes with each gear 36. Shaft 32 is connected to drive 38. Position 39 denotes the brake assemblies of shafts 6, position 40 - adjustable stops.

0 The clamshell feeder operates as follows.

In the initial position, the grab rulers 4 are separated, respectively, and the sliders 5, which are in contact with

2 with the surfaces a of copiers 28 with the carriages 9 lowered on the surface in station 1, and the driven shaft 33 is braked by the braking unit 39. When the drive 38 is turned on, the housing 31 rotates because it is unbraked, and with it

0 and gears 30 (toothed), moving the slats 24, which through the hinge links of the lever 25 and the hinges 26 move the clamshell 4 in the longitudinal direction. When reaching the slats 24

 fixed stops 40, they stop, stopping the clamshell line 4. Nature 38 continues to rotate the drive shaft 32 in the same direction. In this case, the driven shaft 33, breaking the force of friction of the brake assembly 39, if braking

Q constant, or disinhibiting, on command begins to rotate, transferring the rotating gears — gears 35, 23, 20, and 21 — rotating gears through the system. Shafts 14, rotating in different directions, rotate gears 15, 18, and 12 and re 5 Sliders 5 meet each other. The carriage 9, in this case, is fixed, since its own weight and also the surfaces of different copiers 28 prevent its rise.

O When the poses reach 5 stops 29 on the carriage 9, they stop, and since they come out of contact with the surfaces and copiers 28 ,. then as a result of gearing in the gearing 15,

18 and 12 and the 5 torque sliders of the carrier 16 and the gear 19 begin to rotate relative to each other, lifting the carriage 9.

When the required lift height is reached, the actuator 38 turns off, the driven

0, the shaft 33 is braked and the actuator 38 begins to rotate in the opposite direction, rotating the drive shaft 32, which in turn rotates the housing 31, since nothing prevents its rotation. The driven shaft 33 is disinhibited, and the slats 24 are relocated in the opposite direction, moving the clamshell 4 until the slats 24 reach the other stops 40.

When the racks stop., They prevent further rotation of the housing 31, and as the driven shaft 33 is disinhibited at this time, it begins to rotate in the opposite direction, rotating the shafts 14. At the same time, the carriage 9 and its mounted parts lower under their own weight and turn drove 16 and t gi 19 relative to each other. The movement of the sliders 5 in the longitudinal reverse direction is prevented by the surfaces from the copiers 28. When the carriages 9 are lowered to the surface in the bed 1 and the sliders 5 come out of contact with the surfaces from the copiers 28, the sliders 5 begin to move in the opposite direction to their original position. Then the cycle repeats.
