Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, and more specifically, to a torsion shear type bolt cold heading machine. Background Art

[0002] A cold heading machine is a stamping machine that operates by transmitting power through pulleys and gears, generating linear motion via a crankshaft, connecting rod, and slider mechanism. The workpiece, formed at room temperature, undergoes plastic deformation or separation of the blank, ultimately forming it into the desired shape. Fasteners and connectors such as bolts, nuts, and screws are typically manufactured using a cold heading machine.

[0003] Traditional torsional shear type bolt cold heading machines often face a problem during the steel bar feeding process. Due to the weight and shape of the steel bars themselves, they will have an adverse effect on the production of bolts. This irregularity may cause the steel bars to be unable to enter the mold smoothly during feeding, or cause deviations during the cold heading process, thereby affecting the bolt forming quality and production efficiency. Therefore, it needs to be modified and optimized. Utility Model Content
