一、概述 汽车生产传统观念一直是与大批量生产方式联系在一起的,但是随着时代的前进,人们需求多样化、个性化的汽车,因此目前汽车生产中已出现了多品种小批量生产方式,特别是国外轿车、微型车、轻型客车更为突出。在大批量生产小,压机土产线和成套模具的价格昂贵,尤其是车身冲压生产线,只能靠提高设备和整条生产线的多负荷来加速资金的回收;若采用结构简单的成套模具或主要工序(如压延+局部成形)配备模具来完成一些传统的工序,这样手工的劳动量就很大,且零件质量不易保证,在现代冲压技术发展水平上是不可取 First, an overview of the traditional concept of car production has always been associated with mass production methods, but as the times advance, people demand a variety of personalized cars, so the current car has emerged in a variety of small batch production methods , Especially foreign cars, mini cars, light buses are more prominent. In large-scale production of small, press lines and sets of molds expensive, especially the body stamping production line, only by increasing equipment and the entire production line to speed up the multi-load recovery of funds; if the use of simple structure of the mold or the main Processes (such as rolling + local forming) equipped with molds to complete some of the traditional processes, such a large amount of manual labor, and parts quality is not easy to guarantee that the level of development of modern stamping technology is not desirable
