Wire Rope Thimble Molds Has A Significant Impact

The thermal processing quality of wire rope thimble molds has a significant impact on the performance and service life of wire rope thimble molds. From the analysis and statistics of the wire rope thimble mold failure, it can be seen that the wire rope thimble mold failure 'accident' caused by improper heat treatment accounted for more than 40%.?

The quenching deformation and cracking of the wire rope thimble die parts, the early break of the use process, are related to the hot working process of the tool.This is an important part of the wire rope thimble mold work part manufacturing process. For wire rope thimble molds for high alloy tool steels, technical requirements are often imposed on metallographic structures such as material carbide distribution. In addition, the forging temperature range should be strictly controlled, the correct heating specification should be established, the correct forging force method should be used, and the post-forging slow cooling or timely annealing should be carried out. Pre-heat treatment processes such as annealing, normalizing or quenching and tempering should be used depending on the materials and requirements of the wire rope thimble mold working parts to improve the structure, eliminate the structural defects of the forged blank, and improve the processing technology. The high-carbon alloy wire rope thimble die steel can eliminate the reticulated secondary cementite or chain carbides by appropriate preliminary heat treatment, spheroidize and refine the carbides, and promote the uniformity of carbide distribution. This will help to ensure the quality of quenching and tempering and improve the life of the wire rope thimble.
