在冲压件行业里，冲压有时也称板材成形,但略有区别。所谓板材成型是指用板材、薄壁管、薄型材等作为原材料进行塑性加工的成形方法统称为板材成形，此时，厚板方向的变形一般不着重考虑。

In the stamping industry, stamping is sometimes referred to as sheet metal forming, but there is a slight

The so-called sheet forming means the forming method of plastic forming with sheet, thin-walled tube and thin material as raw material, which is called sheet forming. At this time, the deformation of the thick plate is generally not cidered.

管材的锯削：选用细齿锯条，当管壁锯透后随即将管子沿着推锯方向转动一个适当角度，再继续锯割，依次转动，直至将管子锯断。锯割时管子必须夹正。

Cutting of pipe: select a fine toothed saw blade, when the tube wall is sawed through a proper angle along the direction of the push saw, then continue sawing and turn, until the pipe is sawed. When sawing is cut, the pipe must be clamped.

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.
