How to set the process parameters of high-speed press for stamping connector terminals?

   The following are some common methods of setting process parameters and considerations when stamping connector terminals with a high-speed press:
    Stamping speed
    Process Parameters of Socket End

        Considerations: the material, thickness, shape complexity, equipment performance and product quality requirements.
        Setting method: generally based on the material and thickness of the first preliminary estimate. For the thinner and simple shape of the terminal, you can start from a higher speed to try, such as 800 - 1000 times per minute; for thicker or complex shape of the terminal, start from a lower speed, such as 500 - 700 times per minute. Then through the test punch, observe the quality of the terminals and the stability of the equipment operation, and gradually adjust to the optimal speed.

    Punching Pressure
        Considerations: Strength and hardness of the terminal material, size and shape of the terminal, and the structure of the mold.
        Setting method: According to the mechanical properties of the material and the stamping area of the terminal, the required punching pressure is estimated through the calculation formula. A certain safety factor is then taken into consideration, usually between 1.2 - 1.5. For example, if the theoretical punching pressure is calculated to be 10 tons, the actual set punching pressure can be 12 - 15 tons. In the actual press, fine adjustments are made according to the molding results of the terminals.
    Die Clearance
        Considerations: The type and thickness of the terminal material, and the requirement for terminal accuracy.
        Setting method: Generally, the mold clearance is 8% - 12% of the material thickness. For example, for 0.5mm thick copper terminals, the mold clearance can be set between 0.04 - 0.06mm. For terminals with high precision requirements, the gap should be taken as a smaller value.
