  • Mold design of cold drawn steel pipe
    Oct 29, 2018

    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:

    (1) The sizing size of the inner and outer molds should be determined by considering the rebound amount of the finished product after cold drawing, and the material with low hardness and small deformation, which has small rebound amount, high hardness and large deformation, and its back Large amount of bomb;

    (2) The surface of the mold should have lower roughness requirements, generally one to two grades lower than the finished product;

    (3) The mold material is made of high-strength wear-resistant material.
