Cold heading machine clamp mechanism

Abstract

The invention discloses a cold heading machine clamp mechanism. The cold heading machine clamp mechanism comprises a clamp base and a rotating shaft rotatably arranged in the clamp base; the clamp mechanism is characterized in that the rotating shaft is designed in a manner that an upper shaft and a lower shaft are arranged in a segmented manner, the upper shaft drives the lower shaft through gear reduction, the ratio of the rotating angle of the upper shaft to the rotating angle of the lower shaft is 2:1, the upper shaft is connected with a gear capable of turning over by 180 degrees, the lower shaft is connected with a clamp, the clamp is provided with a mounting hole and is used for mounting of a clamp piece, and only one clamp piece is arranged; the clamp piece is provided with a clamp handle portion inserted in the mounting hole and a clamping portion used for clamping a cold heading workpiece, the clamping portion is provided with a rectangular clamping hole with a side opening in the front face direction, an elastic positioning part is arranged on the wall of the rectangular clamping hole, the side direction of the clamping portion is in an L shape, and due to L-shaped design, the clamping portion avoids the stamping action space when a cold heading die carries out cold heading on the side face of the workpiece. The mechanism is uses for cold heading of the workpiece side face, the structure is simple, and the application range is wide.

Description

technical field [0001] The invention relates to a cold heading machine, in particular to a clamping mechanism of the cold heading machine. Background technique [0002] Cold heading machine is a kind of equipment that cuts and cold extrudes various processed metal wires, and makes the wires cold heading in the mold. It is used to process various standard and non-standard fasteners and automobile and motorcycle accessories. In the prior art, the clamping mechanism generally only performs 180-degree inversion, so that the cold heading die can perform cold heading processing on the workpiece in both directions, and the side surface of the workpiece cannot be cold heading. For this reason, some people have designed a clamp that can be turned 90 degrees outward, but there are problems: the structure is complex, not only the cold heading position on the side of the workpiece is limited by the alignment with the cold heading die and the bottom die, that is, the side of the workpiec...

Problems solved by technology

For this reason, someone has designed a clamp that can be flipped 90 degrees outward, but there are problems: the structure is complex, not only the cold heading position on the side of the workpiece is limited by the alignment with the cold heading die and the bottom die, that is, the side of the workpiece The cold heading position can not deviate too much from the center, and limited by the design of the clamp, the side of the workpiece can only be cold heading the shape of the hole, so the scope of application is narrow
