SU12484A1 - Tool for punching heads on bolts using pressure pads - Google Patents

Description

In the proposed device, designed for punching a bolt on bolts using pressure pads, the latter are placed on elastic struts that allow, in order to aaagatil the workpiece, the pads come together with interchangeable dies inserted into them, and to rest the workpiece during punching along one of the anvil racks.

In the schematic drawing of FIG. 1 is a side view of the proposed fixture; FIG. 2 - view it from above.

In plate A, elastic stacks B are reinforced with pads B carrying the displaceable matrices / and covered by frame D, rigidly attached by means of viptov to one of the pads B. A wedge G, placed at one end in frame D, is intended to bring the shoes together, and for spreading out clip 5, inserted between the uprights B in the lower part. Perestavnaya on one of the racks -B anvil K serves as an emphasis for the workpiece during the upsetting head.

Sliding clip 3, pushing up the pillars J together with the pads B and the dies inserted in the last, then the workpiece is inserted and zagimyut it, pushing the wedge 5 and knocking clip G, under the action of which the pillars B together with the pads B approach each other. The stamping of the headboard is done by sealing the protruding part of the workpiece, which can be done manually with a sledge hammer.

Subject matter

A device for punching heads on bolts by means of pressure pads, characterized by the use of elastic pillars B with pads B, covered by frame D, rigidly connected to one of the pads carrying each replaceable matrix G, in which the frame L with a wedge designed to move one of the pads, for the purpose of clamping between the dies of the –P of the workpiece when the head is deposited on it, and the rest of the workpiece serves as a swiveling along one of the posts of the anvil B –K.
