What Factors Determine The Size of The Edge Value of Metal Stamping Parts?

The size of the edge value of metal stamping parts mainly depends on the following aspects;

1.Mechanical properties of metal stamping materials. The edge value of hard materials can be smaller, while the edge value of soft and brittle materials should be larger;

2.The thickness of metal stamping materials, the thicker the material, the greater the edge value;

3.The shape and size of the punched parts. The more complex the shape of the part, the smaller the fillet radius, and the larger the edge value needs to be taken;

4.Feeding and blocking methods; When using manual feeding, the edge value of the side pressure device can be smaller; The edge value of using the side blade to set the distance is slightly smaller than the edge value of using the blocking pin to set the distance;

5.Unloading method; The edge value of elastic unloading is slightly smaller than that of rigid unloading.
