[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten and connect two parts with through holes.

[0003] When producing bolts, a thread rolling machine is needed to roll the threads of the bolts. The thread rolling machine has a pair of rolling wheels with the same parameters, which are installed on the two main shafts of the thread rolling machine respectively and can rotate synchronously in the same direction under the drive of the transmission mechanism. The second rolling wheel is adjusted by the adjustment mechanism to coincide with the indentation of the first rolling wheel on the surface of the workpiece, and a thread is rolled out on the surface of the workpiece.

[0004] During the process of rolling external threads, the workpiece will move downward due to the force, so a support rod is set under the workpiece to limit and support the workpiece, and the support rod is arranged parallel to the workpiece. However, the friction between the support rod and the workpiece is large, which will cause burrs on the top of the thread teeth, affecting the quality of the thread. The support rod itself is also prone to wear and has a short service life. Utility Model Content
