When it comes to stamping, we must explain "continuous die". If there is a complex part that requires extremely complicated stamping processing, for example, it requires 10 stamping steps, which may include punching, bending and stretching, etc. If it is processed step by step, 10 pieces of equipment and 10 workers will be needed, and each machine The operator needs to carry out feeding and unloading actions. Obviously, the cost will be high and the production efficiency will be low. If the punching machine capacity and mold space permit, you can use rolls as raw materials, and use automatic feeders to send the materials to the inside of the punch mold for processing. All stamping processes are integrated into a set of molds, and the rolls are fed forward gradually in a quantitative manner. . Each quantity of blank material will be formed through all stamping procedures. During the forming process, the blank material will be connected to the material belt, and finally it will be punched and separated. In this way, all forming processes can be completed on one punching machine, and single part processing can also be used with the assistance of a robot arm. Therefore, cost, efficiency and product quality can be greatly improved. Of course, products must reach a certain quantity to be economically beneficial, so "continuous die" is the main production type of today's mass-production stamping production lines.
