摘要：

随着金属板料精冲挤压复合成形技术水平的不断提高及应用范围的不断扩大，国内缺少相应的国家标准来规范其工艺过程和技术要求的问题日益凸显，给精冲挤压复合成形工艺的进一步推广应用带来诸多不便。在总结分析精冲挤压复合成形技术的发展及产业现状的基础上，详细介绍了我国精密冲裁领域的标准制修订历程及现状，进而阐述了国家标准《金属板料精冲挤压复合成形件工艺规范》和《金属板料精冲挤压复合成形件通用技术条件》研制的迫切性和必要性。同时，详细介绍了两项标准的研制背景和主要技术内容，旨在引导广大精冲企业使用该标准，规范行业发展。

With continuously improving technological level and expanding application range of fine blanking combined with extrusion process for sheet metal，the problem of lacking corresponding national standard to specify its process and technical specification is increasingly emerging, which causes inconvenience for general application of fine blanking combined with extrusion process. Based on the summary and analysis of technological development and industry status of fine blanking combined with extrusion process，the course and status of drafting and revising of standards in domestic fine blanking field were introduced in detail，and the urgency and necessity of developing national standards Sheet metal parts fabricated by fine blanking combined with extrusion process—Technological specification and Sheet metal parts fabricated by fine blanking combined with extrusion process—General specification were expounded. Simultaneously，the developing background and main technical contents of two standards were introduced in detail to guide the extensive enterprises of fine blanking to use the standard and regulate the development of fine blanking field.
