再论冷锻工艺知识结构体系

On constructional system of technological knowledge for cold forging

在分析冷锻加工技术发展过程、最新动向及其加工工序分类研究进展的基础上,从冷锻变形中变形区及变形特点角度,提出冷锻加工基本工序分为单一变形工序和复合变形工序两大类11组,即单一变形工序分为镦锻、型锻、挤压、模锻、压印、整径和变薄7组,复合变形工序分为复合挤压、其它二合一工序、三合一工序、四合一以上工序4组的分类理念,从而,对冷锻工艺构成提供了一种更为完整的工艺知识结构体系。

On the basis of development process and new trends and classification study of cold forging, a new conception is put forward from the standpoint of deformation region and deformation mechanics characteristic, in which basic process of cold forging is classified as 2 - types and 11- classes, i. e. single deformation process is classified as 7 - classes, including upsetting, swaging, extrusion, die forging, coming, diametrical finishing, ironing; composite deformation process is classified as 4 - classes, including composite extrusion, other two processes in one, three in one, four or more in one. Thus a more integrated constructional system of technical knowledge for cold forging is established.
