The mold handle and the upper support are fixed together, the punch fixing plate is connected with the upper support, if it is a formal installation mold, the discharge plate should be set on the punch to unload the waste or products that are set on the punch; The bottom plate is fixed to the working surface of the punching machine, and a die is installed on it for blanking processing.

The gap between the die and the punch die of the unmanned vending machine is based on the thickness of the blanked sheet, and the material plate is to retire the scrap or punched product from the punching die after blanking; The fixing plate is to fix the punch, connect the punch with the slider of the punch, and use it for punching or blanking processing, which is used to install small punches.

In this case, a hole in the shape of a punch is made on the fixed plate, but the requirement is to fit tightly, and then sink a hanging table hole on the back to prevent the punch from being pulled out when stamping the product. The manufacturing methods of shrapnel include cold coiling method and hot coil method. The shrapnel wire diameter of less than 8 mm is generally used by the cold coiling method, and the hot coiling method is used for those with a diameter of more than 8 mm. Some shrapnel is also subjected to strong pressure or shot peening after being made, which can improve the carrying capacity of the shrapnel.
