Basically, all precision stamping parts processing plants want to stretch high-quality stretch stamping parts. Therefore, the factory needs to reasonably judge the stamping direction of the stretch stamping parts. Then how to judge reasonably?

1. The punch can enter the die. The shape of the lower right side of the die protrudes outward, protruding the scale of the die opening, so that the punch cannot enter the die. This stretching direction cannot be stretched. Change the stretching direction to enable the punch to enter the die.

2. Make the area of the punch contact with the blank large. The larger the contact surface, the smaller the angle between the contact surface and the horizontal plane. The less prone the blank is to some stress overload and splitting the parts. When stretching, the die sticking function is advanced, and a flawless punch shape is simply obtained, which is conducive to the deformation degree of the forward stamping parts.

3. Some feed resistance on each pressing surface should be uniform and reliable. Uniform stretching is a prerequisite for uniform and reliable feed resistance on each pressing surface. And uniform feed resistance on each pressing surface is important for stretching stamping parts to not wrinkle or crack.

When precision stamping parts processing plants can take note of these during the stretching process, they can produce high-quality stretching parts to a large extent.
