SU12391A1 - Gripping device for pigs - Google Patents

Description

In the proposed gripping device, the discs use rollers suspended by bolts to the frame moving along the guide frames of the fixture, when being lifted, the rollers are wedged between the surface of the bars and the inclined surfaces of the frame crossbars.

In FIG. 1 depicts a top view of a special gevil; FIG. 2 - cut it on AB-ft: 1; FIG. 3-piece fitting.

The device consists of a frame 1, equipped with crossmembers 2 with inclined side surfaces, over which the rollers 3 can slide or roll on the trunnions of which the bolts 4 threaded into the slots of the roll 5 moving along the guide pin 8 are mounted with their eyes (Fig. 1-3 ). When raising the rash 5 using the clip b, all the rollers can be simultaneously pulled up. With the aid of lugs 9, the fixture is lowered with 1 sl to the pas group of blanks a, at which each ingot enters the interior of the frame, lifts the roller 3 for as long as

until it falls between the side surface of the flange 1 and the flap surfaces of the cross member -2. During the subsequent lifting of the device, the rollers with friction force are carried down into the formed wedge-shaped gaps and, causing considerable pressure and training forces. make it possible to simultaneously lift all blanks.

To release the fixtures, it is sufficient to lower a group of discs on the BCJ floor, at the same time raising frame 5 with all the frames hanging from it. bolted with rollers.
