Hardware tells you how to effectively solve the chip jumping generated by precision stamping parts

If the chip jump of the precision stamping die is caused by the large blade gap, the lower limit of the blade gap can be set in the design section. That is, GAPu003d(4%~6%)T. Or change the blade form to the blade The upper part has a straight line section of 3 -5mm, and the lower part is processed into a slightly larger slope (0.5°-1.0°) to enhance the wear resistance of the knife edge. The chip jumping caused by the insufficient length of the punch should be in accordance with the requirements of the drawing. However, for the chip jumping caused by the too large contact area between the punch and the blank, the shape of the punch can be changed to reduce the contact area. For the chip jumping caused by the loosening of the knife edge of the precision stamping part, the countermeasure is to process the frame of the template into a replaceable type. If you add too much punching oil to the chip, you must specify the dripping method, and the execution layer must be implemented. The punching oil has a high viscosity, and you can choose a slightly volatile punching oil. For precision stamping parts caused by the simple chip shape, the solution is to complicate the shape of the blank. For round blanks, when designing precision stamping dies, the positions of the two semi-circle centers that make up the circle can be staggered by 0.002~0.005mm.
