Design of guide pin (punch):The diameter of the guide pin (punch) and the gap between the guide hole and the material guide hole are designed according to the thickness of the material. The shape of the guide pin's front end can be roughly divided into two types: A. artillery projectile and B. cone (push-pull).
(1) The shell shape is a common form, and there are also standard parts on the market.
(2) The conical shape has some angles, which are suitable for high-speed stamping of small parts. The decisive factors of the drawing angle are stamping stroke, material of the processed parts, size of the guide hole, processing speed, etc. It is easier to correct the position of the processed material when the pulling angle is large, but the length of the pulling part will be longer. The connection between the pull-out part and the cylinder part should be smooth.
