温热挤压兼有冷挤压和热挤压工艺的优点,是一种很有前途的压力加工工艺。但是由于目前温热挤压的模具设计和润滑冷却方法等技术问题还没有完全解决,限制了它的广泛应用。温热挤压模具结构与冷挤压相比有其共同之处,但是由于温热挤压有其自己的特点——被加热的毛坯容易使模具软化、局部 Warm extrusion both cold extrusion and hot extrusion process advantages, is a promising pressure processing technology. However, due to the current hot extrusion die design and lubrication cooling methods and other technical problems have not been fully resolved, limiting its wide range of applications. Hot extrusion die structure and cold extrusion has its similarities, but because of the hot extrusion has its own characteristics - the heated blank is easy to soften the mold, the local
