略论冷压成形之本质特征及技术构成

Abbreviation on Deformation Original Characteristics and Technological Components of Cold Pressure Forming

基于金属塑性加工可分为冷、热两类的观点,强调了应该从变形实质、工件质量和环境质量之材料成形加工三内涵的综合角度,对成形的本源内容进行研究。深入分析了主要由冲压和冷锻构成的冷压成形之技术特点(与热压成形对比)。根据分类概念和分类法基本原理,较系统地总结了冷压成形的本源内容及其技术构成,提出了冷压成形(包括冲压、冷锻以及它们的组合加工三大部分构成)的一种工艺知识结构体系。研究结果能为冷压成形乃至整个塑性加工改进传统工艺、研发原创新工艺和学科理论发展,为提高其CAD的技术水平以及制订其发展方略与组织方式,提供一种依据和参考。

Based on the standpoint that metal plastic working（or forming） can be classified as cold and hot working,it is emphasized that the original substance of deformation should be researched in a synthetical viewpoint which includes three facets i.e.deformation essence,workpiece quality and environmental quality.Technical characteristics of cold pressure forming,mainly including stamping and cold forging,are further analyzed（and be compared with those of hot pressure forming）.Based on classification scheme and its essential principle,systematically summarize original substance of cold pressure forming and its components,and propose a constructional system of technological knowledge of cold pressure forming（includes three catagories i.e.stamping,cold forging and their combined working process）.The research results can improve traditional processes and develop new processes in cold pressure forming and even in plastic forming,and also can give a reference to enhance technical level in computer aided application and to establish development strategy and organizational methods.
