What is the purpose of the stop pin in the production of stamping parts?

In the process of producing stamping parts, the function of the stopper pin is to ensure that there is an accurate feeding distance when the strip is fed; the stopper pin can be divided into three types according to the structure, and what kind of function they play in the production of stamping parts What's the role? Let's take a look; the first type: fixed stopper pin. When the fixed stopper pin is fed, the strip needs to be manually lifted and fed, and the stopper pin is inserted into the next hole, so that the positioning point is close to the material pin. The second type: start to use the stop pin. In the production of stamping parts, start to use the stop pin for the first positioning when the strip is fed. When in use, press out the stopper pin by hand. After the strip is positioned, the stopper pin will automatically exit under the action of the spring; the third type: movable stopper pin, the movable stopper pin has a slope in the feeding direction and is fed When the overlapping edge collides with the inclined surface, the stop pin jumps over the overlapping edge and enters the next hole. Then the strip is pulled back, and the stop pin is positioned against the overlapping edge. Each feeding should be sent first and then pulled. It is suitable for stamping materials with a thickness greater than 0.8mm.
