第四章钢的冷挤压变形力冷挤压变形力的确定,就是考虑各种主要因素的影响,正确求得钢在冷挤压变形时的单位冷挤压变形力(单位冷挤压力)。单位冷挤压力是冷挤压工艺的重要参数,它是拟定冷挤压件合理变形工艺及正确进行模具设计的主要依据,特别是关于模具材料的选择。目前冷挤压的模具材料所能够承受的最大单位压力为 Chapter IV cold extrusion deformation of steel Cold extrusion deformation of the determination is to consider the impact of various major factors to correctly obtain the steel cold extrusion deformation unit cold extrusion deformation force (unit cold extrusion pressure ). Unit cold extrusion pressure is an important cold extrusion process parameters, it is to develop a reasonable deformation of cold extrusion process and the correct basis for the design of the mold, especially on the choice of mold materials. The current cold extrusion die material can withstand the maximum unit pressure
