In fact, for the stamping parts to understand the knowledge is really a lot of questions are usually you can not touch, in the same industry is not the same stamping parts, to understand the knowledge points are not the same, the following by our Hengji Up to the hardware to give us a simple understanding.
In general, we are so sure that the scale of the stamping parts. We do not want to think about twists and turns makes the data thinner. Accounting method is very simple, the first is to ask some of the neutral radius of the neutral layer R (find the neutral layer azimuth coefficient x, R = r + xt), and then according to the arc length formula to find the length of the bending section open. Finally sum can be. If you want to think about twists and turns some data thinning, it is necessary in accordance with the principle of the same volume accounting rough, the demand for further revision.
The other is the stamping parts of the scale accuracy and appearance roughness is directly in accordance with the device drawings can be marked, usually the stamping parts of the roughness of the surface does not make the request, we put the primary request reflected in the original information on the selection, Steel plate material should have a very severe time. If you can not rely on the original data to ensure that the appearance of roughness, we add in the late polishing, plating and other technologies.
