Focus on rubber metal shock absorber parts for 15 years
| Actually for stamping parts to understand the knowledge really is a lot of, a lot of problems are normally you can't touch, in different industry application of different stamping parts, to understand the knowledge points are not the same, the following by Rong induced Yuhuan stamping to simple for everyone to do understand. In general, we are the size of the expansion of the stamping parts. First of all, we don't think about bending the material. The calculation method is very simple, the main is to first seek the bending part of the neutral layer radius R (find out the neutral layer position coefficient X, R=r+xt), and then according to the arc length formula to calculate the bending segment expansion length. Finally sum. If you have to consider the bending part of the material thinning, it is in accordance with the principles of the volume of the same volume blank, need to be further amended. Also is stamping parts size precision and surface roughness accuracy is directly installation drawings marked in accordance with the can, usually by stamping the surface rough degree is not required, Rong induced Yuhuan stamping reminds us the main requirements embodied in the choice of raw material, plate of raw materials on the order should have very strict requirements. If the surface roughness can not be guaranteed by the raw material, we will add polishing, plating and other processes in the late stage. |
