在现代机械制造业中,设计与制造工艺装备的劳动量占很大的比重,制造工艺装备所消耗的材料也相当可观。还由于产品的不断发展和更新,将导致大量工艺装备的报废。因此,如何适应多品种、小批量生产的特点,国内外曾经探索过多种途径,如压缩工装系数等。近年来,我部绝大多数工厂采用了组合夹具,在新品试制当中发挥了良好作用,缩短了试制周期,不少单位在批生产中也采用了,这比压缩工装系数大大地前进了一步。但由于生产、技术管理跟不上,组合夹具的元件供不应求,又不配套,因此,它的使用受到了一定限制。而“成组加工”这种生产作业方式,可以占领专用夹具和组合夹具之间的“空间地带”,它一
In the modern machinery manufacturing industry, the labor involved in designing and manufacturing process equipment accounts for a large proportion, and the materials consumed in manufacturing process equipment are also considerable. Also due to the continuous development and updating of products, will lead to a large number of scrapped technology and equipment. Therefore, how to adapt to the characteristics of multi-species, small batch production, both at home and abroad have explored a variety of ways, such as compression tooling coefficient. In recent years, most of our mills have adopted combination fixtures, which have played a good role in the trial production of new products and have shortened the trial period. Many units have also adopted them in batch production, which is one step ahead of the compression tooling factor. However, due to production, technical management can not keep up, the combination of components in short supply fixture, but not supporting, therefore, its use has been subject to certain restrictions. The “group processing” This mode of production operations, you can occupy the special fixture and the fixture between the “space zone”, it is a
