Design of Hydraulic Cylinder Cold Drawn Tube mould

- Aug 28, 2020-

The cold drawn tube is drawn by a mold of a certain shape and size under the action of force. The dimensional accuracy and surface quality of the mold directly affect the dimensional accuracy and quality of the finished product. Mold design should pay attention to the following aspects: the size of the inner and outer mold sizing should be considered after the cold-drawn product, the generally low hardness, small deformation of the material, its springback is small, high hardness, deformation Large materials have a large amount of resilience; the surface of the mold must have low roughness requirements, and the value is generally one to two levels lower than the finished product; the mold material uses high-strength wear-resistant materials.
