一、前言高速锤挤压模锻机是新型的先进锻造设备,其特点是打击速度高、能量大。所以相应地要求锻模必须能承受高冲击载荷下的挤压应力和高速流动着的固体金属摩擦力。过去这种模具是用锻压成型的合金工具钢块进行机械加工,再经钳修和热处理等工序制造。制造周期长,寿命不稳定,以致供不应求。在党的基本路线指引下,在批林批孔运动的推动下,
I. Introduction High-speed hammer extrusion die forging machine is a new type of advanced forging equipment, which is characterized by high strike speed, high energy. Therefore, correspondingly, the forging die must withstand the compressive stress under high impact load and the solid metal friction force flowing at high speed. In the past this mold is forged alloy tool steel for machining, and then clamp and heat treatment processes such as manufacturing. Long manufacturing cycle, unstable life expectancy, resulting in short supply. Under the guidance of the party’s basic line and under the motto of "criticizing the proletarian and bachelor Kong Kong holes,
