Description

Technical Field

[0001] The utility model relates to the technical field of cold drawing machine jaws, in particular to a detachable cold drawing machine jaw. Background Art

[0002] A cold drawing machine is a device used for cold processing of metal materials. The cold drawing machine uses a strong pulling force to forcibly pull metal materials (such as steel, etc.) through a die hole smaller than its original diameter, causing the material to undergo plastic deformation at room temperature, thereby reducing the material diameter, increasing the length, and improving the material properties. During the cold drawing process, multiple cold drawing passes are usually used to gradually reduce the material diameter to achieve the required dimensional accuracy and performance requirements. During the cold drawing process, the jaws of the cold drawing machine are mainly used to firmly clamp the processed steel and other materials, providing a stable clamping force for the cold drawing operation to ensure that the material will not slip during the cold drawing process. It can withstand a large pulling force, allowing the material to pass through the cold drawing die smoothly, achieving the purposes of reducing the diameter, increasing the length, and improving the material properties.

[0003] When a cold drawing machine is cold drawing a material, jaws are generally used to clamp the material. However, the clamping positions of most current jaws are fixed, which may make it impossible to firmly clamp different materials, resulting in poor practicality.
