Cold heading forming machine

Abstract

The invention discloses a cold heading forming machine, comprising a wire rod straightening part, a wire rod feeding part, a wire rod cutting part, a cold heading forming part and a front and back through part; the cold heading forming machine is characterized in that the wire rod feeding part performs feeding by adopting a manipulator, and the wire rod straightening part makes adjustment by adopting a manipulator. The cold heading forming machine is simple in structure, small in occupied space, and accurate and reliable in fixed length feeding, and a better straightening effect of a metal wire rod can be realized by action of a stopping manipulator.

Description

technical field [0001] The invention relates to an improved invention of a cold heading forming machine. Background technique [0002] The cold heading forming machine is a kind of equipment that cold-extrudes various processed metal wires and makes the metal wires cold-headed in the mold. It is used to process various standard and non-standard fasteners and automobile and motorcycle accessories. In the prior art, the feeding of the cold heading forming machine is through the reciprocating motion of the driving arm, which drives the ratchet to push the ratchet gear to rotate intermittently, and finally drives the feeding wheel to rotate for feeding. The above-mentioned feeding mechanism has a complex structure and high noise. When the machine breaks down, the feeding cannot be stopped in time, and the ratchet gear will often reverse to a certain extent and the feeding wheel will retreat. In this way, the feeding length will be insufficient, resulting in unqualified product q...

AI Technical Summary

Problems solved by technology

The problems in the above-mentioned straightening process mainly include: the coil material is naturally loose and placed horizontally, occupying a large space, the metal wire is randomly introduced between the upper and lower traction wheels, and the center of the metal wire at the introduction end is often deviated from the traction center of the upper and lower traction wheels Larger (including position deviation and angle deviation); also, because the coil is placed horizontally, the metal wire is circumferentially bent in the horizontal plane, and after passing through the traction wheel, it must first be aligned in the vertical direction, and then Alignment in the horizontal direction, which is obviously not conducive to the alignment effect
