[0002] The self-expanding bottom type mechanical anchor bolt rod is usually the core component of the anchor bolt, which is used in cooperation with a nut, a gasket, a cone head, and an expanding piece. The screw rod is generally made of high-strength steel or stainless steel, and has high strength and corrosion resistance.

[0003] The thread rolling machine is a machine tool for processing threads, straight lines, and inclined lines, and is an advanced non-cutting processing method that can effectively improve the quality of the inner surface of the workpiece. The radial pressure stress generated during processing can significantly improve the fatigue strength and torsional strength of the workpiece. It is an ideal process with high efficiency, energy saving, and low consumption. Currently, in the process of processing the self-expanding bottom type mechanical anchor bolt rod, a thread rolling machine is generally used to process threads on the self-expanding bottom type mechanical anchor bolt rod.

[0004] The thread rolling machine in the prior art is used by feeding the metal rod into the space between the two thread rolling wheels through the feeding device, and then driving the self-expanding bottom type mechanical anchor bolt rod to retreat through the feeding device after the thread processing is completed.
