[0002] Cold heading machine is a special equipment mainly for upsetting, which is specially used for batch production of fasteners such as nuts and bolts. The earliest cold heading machine in the world originated in Germany. At that time, the purpose of developing cold heading machine was mainly to manufacture bullet shells in large quantities during World War II. The cold heading process is based on the theory of metal plastic deformation. A certain pressure is applied to the metal blank at room temperature to make it plastically deform in the mold cavity and form it into a specified shape and size. The cold heading machine needs to straighten the iron wire when it is transported through a conveying device and enters the cold heading machine for processing. Most of the existing straightening devices use straightening wheel groups for straightening, but the spacing between the existing straightening wheel groups is mostly the same. It is inconvenient to change the spacing between the straightening wheel groups according to needs to deal with iron wires of different diameters, which is inconvenient to use. Therefore, we propose a cold heading machine straightening device with a support plate at one end. Utility Model Content
