fastener哪家好-圣霖国际【用心服务】

简单来说钣金件是金属薄板壳体，冲压件就是用拉伸机或冲床等加工的工件1，钣金件在折弯过程中厚度不会有变化，fastener种类，但在汽

车钣金壳体中应为敲击等原因，一部分表面会有一定变化。冲压厂是不能确定落料尺寸的，应该是在定做模具时由模具厂试定出来的。

In a simple way，fastener哪家好， the sheet metal part is a metal sheet shell， and the stamping part is 1 of the workpiece， which is processed by a drawing machine or a punch press. The thickness of the sheet metal parts will not change during the bending process， but in the steam.

The surface of the automobile shell should be knocked and so on. Part of the surface will change. The stamping plant is unable to determine the blanking size. It should be determined by the mold factory when making the mould.

五金冲压件应用领域

汽车行业的冲压。以拉深为主。在我国这部份主要集中在汽车厂、拖拉机厂、飞机制造厂等大厂，四平fastener，***的大型冲压拉深厂还未几见。

Application field of metal stamping parts

Stamping in the automobile industry. It is dominated by deep drawing. In China， this part is mainly conceated in automobile factories， tractor factories， aircraft manufactory and so on. Independent large stamping and drawing plants are not yet seen.

⑴设计的冲压件必须满足产品使用和技术性能，并能便于组装及修配。

⑵设计的冲压件必须有利于提高金属材料的利用率，减少材料的品种和规格，尽可能降低材料的消耗。在允许的情况下采用价格低廉的材料，尽可能使零件做到无废料及少废料冲裁。

⑶设计的冲压件必须形状简单，结构合理，以有利于简化模具结构、简化工序数量，即用少、简单的冲压工序完成整个零件的加工，减少再用其他方法加工，并有利于冲压操作，便于***实现机械化与自动化生产，以高劳动生产率。
