Description

Technical Field

[0001] The utility model relates to a field, in particular to an auxiliary structure for discharging materials of a cold heading machine. Background Art

[0002] A cold heading machine is a special equipment mainly used for mass-producing fasteners such as nuts and bolts by heading. According to the theory of metal plastic deformation, a certain pressure is applied to a metal blank at normal temperature to cause plastic deformation in the die cavity and form it into a specified shape and size. High-quality metal materials with good "plastic deformation" must be selected, such as riveting screw steel, and its chemical composition and mechanical properties have strict standards.

[0003] During the use of a cold heading machine, when a bundle of raw material bars is almost used up, the last small section of the raw material bar is called the tail material. Due to its uncertain length, the length of the tail material fed into the cutting mechanism and upsetting mechanism of the cold heading machine may be insufficient. Therefore, it is necessary to withdraw the raw material. Currently, when discharging materials, manual operation of the equipment is generally used to withdraw the remaining materials. However, manual discharging is not only slow, but also prone to causing injuries to the staff during operation.

[0004] Therefore, we propose an auxiliary structure for discharging materials of a cold heading machine to solve the above problems. Content of the Utility Model
