Description

Technical Field

[0001] The utility model belongs to the technical field of screw rod processing, in particular to a thread rolling machine for screw rod processing. Background Art

[0002] A thread rolling machine is a multifunctional cold extrusion forming machine that can cold-roll workpieces into threads, straight grain, and diagonal grain within its rolling force range. Currently, threading a screw rod is typically performed using a thread rolling machine. During this process, a worker holds the screw rod and inserts one end between the rollers of the machine. Vibration can easily cause the worker's grip on the screw rod to shift, affecting the quality of the threading at the other end. Furthermore, when the screw rod is short, the worker's hand can easily come into contact with the rollers, leading to safety accidents. Utility Model Content
