前言 汽车冲压件的质量一般取决于模具的制造精度,但对于那些形状复杂的汽车覆盖件来说,除模具制造精度外,还需要从模具设计前的工作着手,进行一些相互联系和制约的系统技术保证工作,为设计和制造打下基础。因此提高车身覆盖件的质量是涉及到模具设计和制造技术和检测技术等诸方面的系统工程,在日本,检测技术的具体内容包括:主模型的检查;检验夹具的检查;工艺模型的检查;立体样板的检查;模具的检查;制件的检查等。依靠这些系统检测技术来保证大型冲压件的高质量和高精度。本文试以日本汽车模具主要制造厂之一的富士铁工所的实践为借鉴,介绍上述这些检
Preface The quality of automotive stamping parts generally depends on the manufacturing accuracy of the mold, but for those complex shape of the car cover, in addition to the mold manufacturing precision, but also from the mold design work before, some interconnected and restricted system Technical assurance work to lay the foundation for the design and manufacture. So to improve the quality of body cover is related to the mold design and manufacturing technology and testing technology and other aspects of the system engineering in Japan, the specific content of testing technology include: the main model of inspection; inspection fixture inspection; process model inspection; Three-dimensional model of the inspection; mold inspection; parts inspection. Rely on these system inspection techniques to ensure the high quality and precision of large stampings. This article tries to Japan’s automobile mold one of the major factories Fuji Iron Works practice as a reference, introduce these seized
