冷挤压单位挤压力是冷挤工艺设计中的主要参数,在工程实践中多采用图算表(或称诺模图)来确定。目前国际上有两种比较完整的计算冷挤压力的诺模图,1970年,分别由国际冷锻协会(ICFG)和西德工程师协会(VDI)提出,但它们都不大适合我国钢材的情况。在国内,文献在大量实验数据的基础上,提出了正、反挤压 Cold extrusion unit extrusion pressure is cold extrusion process design of the main parameters in the engineering practice to use more diagram (or nomogram) to determine. At present, there are two complete sets of nomograms for calculating cold extrusion pressure in the world. In 1970, they were proposed by ICFG and VDI respectively, but they are not suitable for the steel of our country Happening. In China, based on a large number of experimental data, the literature proposes positive and negative extrusion
