冲压件的质量,在很大程度上与模具、机床、工件材料和润滑剂密切有关。其中最主要的是模具本身的质量,它涉及模具所用的钢材、模具结构,热处理状态以及热处理后所进行的各种表面处理及其质量。汽车工业中冲压模的质量可分为四级,其寿命、结构与材料见表1。(表中所列模具材料,均以德国DIN标准编号。文末附有各种材料的大致元素成份标号,便于读者参考。——摘译者) 成形加工经济性的最重要指标是模具寿命。钢类经过优良的热处理以及模具表面精心加工之后,模具材料与工件材料之间,最主要问题是产生粘附磨损,
The quality of stamping parts, to a large extent with the mold, machine tools, workpiece materials and lubricants are closely related. One of the most important is the quality of the mold itself, which involves the mold steel used, mold structure, heat treatment and heat treatment after the various surface treatment and its quality. The quality of stamping dies in the automotive industry can be divided into four levels, with their life, structure and materials as shown in Table 1. (Mold materials listed in the table, are in accordance with the German DIN standard number. At the end of the article attached to the general elemental composition of various materials marked for ease of reference.) - Translator) The most important indicator of forming economy is the mold life. Steel after excellent heat treatment and the mold surface carefully processed, the mold material and the workpiece material, the most important issue is the occurrence of adhesion wear,
