[0002] A cold heading machine is a stamping machine used in mechanical manufacturing to shape raw materials into the required shape without altering them. Cold heading machines are commonly used to manufacture fasteners such as bolts, nuts, and screws. In the process of using a cold heading machine, the raw materials used are mostly rigid wire materials. During use, the wire material is placed on a wire feeding frame for feeding and then conveyed to the straightening mechanism consisting of two rows of straightening rollers on the cold heading machine, where it is then processed in the next step, thus enabling continuous feeding.

[0003] Currently, the feeding wheel spacing of most cold heading machines on the market is not easy to adjust. When processing wires of different sizes, it is often impossible to quickly and accurately adjust the feeding wheel spacing, resulting in poor feeding effect or even failure to feed.
