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，独立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.

五金冲压件加工包括冲裁、弯曲、拉深、成形、精整等工序。冲压件加工的材料主要是热轧或冷轧（以冷轧为主）的金属板带材料，例如碳钢板、合金钢板、弹簧钢板、镀锌板、镀锡板、不锈钢板、铜及铜合金板、铝及铝合金板等。

stamping process includes blanking, bending, drawing, forming, finishing and other processes. The main materials for stamping parts are hot rolling or cold rolling (cold rolling), such as carbon steel, alloy steel plate, spring steel plate, galvanized plate, tin plate, stainless steel plate, copper and copper alloy plate, aluminum and aluminum alloy plate.

手锯锯削的注意事项

锯条的松紧要合适，且锯割时压力不能太大，以防折断伤人；

当锯缝歪斜时，不可急于纠正，而需要慢慢地逐步纠正。

Notice of hand saw cutting

The tightness of the saw blade should be suitable, and the pressure should not be too large during sawing, so as to prevent breaking and hurting people.

When the SAW seam is skewed, it can not be corrected in a hurry, but it needs to be corrected gradually.

将闭合的模具放置于雎力机工作台或垫板上适当位置，如果使用气垫，先要放好顶杆，并标记好模具的摆放位置。

手动扳动冲压机床飞轮（或操纵点动按钮），使机床上滑块下行并停于下死点位置。

Place the closed mould on the bench or pad of the mandrel machine. If the air cushion is used, the ejector pin should be placed first and the placement of the mould should be marked.

Manually pull the flywheel of the stamping machine (or  the moving button), so that the slider on the machine tool will be downhill and stop at the bottom dead center.
