Bending stamping properties

what is Bending Stamping Parts?

If the bending stamping parts radius is smaller than the thickness of the material, a punch with a radius at the front end smaller than the thickness of the material must be used, and resort to the imprint bending method. In this way, it requires 10 times the pressure of free bending.

As far as free bending Stamping parts is concerned, the punch and die are processed at 85 ° or less (smaller is better). When using this set of molds, pay attention to the gap between the punch and the concave mold at the bottom of the stroke, and enough to compensate for the springback and keep the material bent excessively about 90 °.

Generally, the springback angle of a free bending stamping parts die on a new bending machine is ≤2 °, and the bending stamping parts radius is equal to 0.156 times the opening distance of the die.

For bottomed concave mold bending, the mold angle is generally 86 ~ 90 °. At the bottom of the stroke, there should be a gap between the male and female dies slightly larger than the thickness of the material. The forming angle is improved because the tonnage of the bottomed die is larger (about 4 times that of free bending), which reduces the stress that usually causes springback within the bending radius.

The embossing bending is the same as the bending stamping parts of the bottomed concave mold, except that the front end of the punch is processed to the required bending radius, and the gap between the convex and concave molds at the bottom of the stroke is less than the material thickness. Due to the application of sufficient pressure (about 10 times of free bending) to force the front end of the punch to contact the material, springback is basically avoided.

In order to select the lowest tonnage specification, it is best to plan for a bending stamping parts radius greater than the thickness of the material, and use the free bending method as much as possible. When the bending radius is large, it often does not affect the quality of the finished part and its future use.
