Stamping parts of the drawing process is a conventional production process, but to do a good job also need to pay attention to some things, stamping parts thinning drawing is generally a process of stretching or extrusion after forming, is a complete very thin-walled cup-shaped parts of the formation process. Next, let‘s learn about the characteristics of thinning and deep drawing in the stamping process and there are two ways of thinning and deep drawing in the stamping process.

The performance of the stretching process of stamped parts in production:

1. The characteristics of thinning and drawing during the stamping process are:

　(1) The gap between the punch and the die is smaller than the thickness of the blank, and the blank is compressed when passing through the gap, resulting in a significant thinning phenomenon; this increases the height of the side wall, so it is called thinning deep drawing.

(2) The quality of the thinner drawing parts is high, and the wall thickness is relatively uniform.

(3) After the drawing parts become thinner, the residual stress is greater, and some even crack after storage in the warehouse, which can be removed by low temperature tempering.

2. There are two methods of thinning and drawing during the stamping process:

　(1) The wall thickness becomes thinner and the inner diameter is also reduced - the deformation and stress are more complex, and the workpiece is prone to cracking, so this method is generally not used

(2) The wall thickness becomes thinner, and the inner diameter does not decrease significantly

The above is a little knowledge about the characteristics of thinning and drawing in the stamping process and the way of thinning and drawing explained by our company.
