Description

Technical Field

[0001] The utility model relates to the technical field of stud production equipment, in particular to an automatic production line for cold heading and thread rolling of studs. Background Art

[0002] Studs are a type of fastener that has no head and only external threads at both ends. For the processing and production of bolts or screws, usually a cold heading machine is used to process a cold heading blank without threads, and then a thread rolling machine is used to process threads on the cold heading blank to complete the preparation of the bolt or screw. After the processing is completed, the product will be discharged from the discharge port.

[0003] At present, the production efficiency of studs is mainly restricted by the processing efficiency of the thread rolling machine. The thread rolling machine cannot perform thread processing on the cold heading blanks produced by the cold heading machine in time, resulting in a large amount of cold heading blanks accumulating in the hopper of the thread rolling machine feeding equipment. Long-term accumulation will cause the surface of the cold heading blanks at the bottom of the hopper to rust, affecting the surface quality of the product and even affecting the processing cycle.
