Description

(54) SHIPPING TRANSPORT DEVICE

one

The invention relates to processing; metals by pressure and can be used. Used mainly in the mechanization of hot multi-positional stamping.

A device for transporting workpieces between machining positions is known, comprising a base, in the guides of which a carriage with grippers is mounted, as well as drive-related mechanisms for moving the carriage in the longitudinal direction and grips in transverse and vertical directions. Clamping movements of lifting and transporting the blanks are driven by separate mechanisms through a cam-type distributor, 1.

This embodiment of the device reduces its speed and reliability.

The purpose of the proposal is to increase the performance and reliability of the device.

This goal is achieved due to the fact that the mechanism of movements is made in the form of a rack-type pusher movable from the power drive mounted on the carriage, fixed on it and interacting with the carriage lugs placed in the carriage and associated transverse slider locks with guide columns mounted in the latter, spring-loaded grips connected to them, connected by hinge links with movably mounted in the sliders of the stem-racks connected to the rack plunger by means of six And a spring-loaded latches polzushkami.

The drawing shows a kinematic diagram of a device for four-step hot stamping on a 15-pin rotary press.

The power cylinder 1 is mounted in a base 2 fixed on the table press (not shown), in whose guides the carriage 3 moves. The carriage 3 has two fixed

The positions provided by the clips 4 of the SHOTEX1 cylinder 1 are connected to a rack pusher 5 moving in guide carriages 3 25 and having rear 6 and front 7 stops. In carriage 3 are mounted transversely. but movable sliders 8 on guide columns 9, which are mounted spring-loaded to them, tongs 30 grippers 10.

The clamping jaws And grips 1K by the hinge link 12 are connected with sliders 8 and installed in the guide pieces; 8 stock rails 13

The movement of the rod rack 13 is transmitted from the rack pusher 5 by means of a gear 14 coupled to it and a gear 15, which sits on the same axis, and engages with the rod rack 13 by means of a pin. and the rod part of the rod-rack 13. The movement of the sliders 8 is limited to the stops 18.

The device works as follows.

After the next working stroke of the press, the power cylinders i turn on the moving rack ram 5, the carriage 3 is locked by the clamp 4 in the guide bases 2 in the forward position. The rack plunger 5 moves the lock rail 13 together with gears 14 and 15 together with the latch 17 connected to it by the latch 17. During long-term movement, the rod-rod 13 pushes the latch 16 and, through the hinge link 12, rotates the sponge 11 of the grippers 10. The workpiece is clamped, since the movement of the rod 13 continues.

The hinge link 12, compressing the spring 19, lifts the grippers 10 with the workpiece above the stamp.

The rail plunger 5 with the rear stop 6, pressing the latch 4, moves the carriage 3 along the front of the press a distance: equal to the feed pitch. In this position, the carriage is locked with latch 4, and the power cylinder 1 automatically switches to reverse. In this case, the rascher pusher rotates the gears 14 in the opposite direction, the rod rail and returns

backwards The clamp clamps 10 are lowered to the stamp and then opened to release the blank. The rod rail, pressing the latch 16, connects with the slider 8 the latch 17 and brings it together with the grippers 10 from the working area of the stamp. After that, the rack plunger 5 with the front stop 7 moves the carriage 3 to the feed step to its original position, after which it is given

team press on the working course. Then the cycle repeats.
