[0002] Mold steel is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die casting dies. Mold materials are the material and technical basis of the mold manufacturing industry. Mold steel is a traditional mold material. Its variety, specification, and quality play a decisive role in the performance, service life, and manufacturing cycle of the mold. In recent years, the output, production technology, process equipment, quality, and variety of mold steel at home and abroad have achieved relatively rapid development. Mold steel is prone to deformation during heat treatment, so equipment for straightening it is required. However, in the existing technology, it is troublesome to fix the steel body when straightening it, and it is not stable enough. Only one specification of steel body can be straightened, and most of them are straightened by stretching the steel body. This may result in the steel body The straightening effect is not good enough, resulting in poor straightening effect and low efficiency; therefore, we propose a mold steel straightening device to solve this problem.
