As an important component in the new energy system, the structural design of the stamping die for new energy electronic control cover is directly related to the quality, production efficiency and cost of the product. Here are some key points.
The first is the design of the cavity and the convex and concave dies. The cavity should accurately match the outer contour of the electronic control cover to ensure that the material can flow evenly and fill the entire cavity during the stamping process, so as to obtain an electronic control cover with precise shape and stable size. The shape and size of the convex and concave dies are of utmost importance, and the sharpness of the cutting edge and the gap setting directly affect the quality of blanking. Reasonable gaps can ensure the cross-sectional quality of the blanking parts and reduce burrs and tearing. For example, for thinner sheets, the gap should be appropriately reduced to prevent excessive deformation of the sheet; for thicker sheets, a larger gap is required to ensure the effective transmission of the blanking force.
Secondly, the positioning and guiding structure of the die is indispensable. The precise positioning device can ensure that the sheet is in the correct position every time it is stamped, avoiding the generation of scrap due to position deviation. Common positioning methods include stop pins, positioning plates, etc. Guide structures such as guide pins and guide sleeves provide precise guidance for the upper and lower die movements of the die, ensuring the stability and accuracy of the stamping process. Even under high-speed stamping operations, the die can be prevented from being damaged due to partial loads, extending the service life of the die.
Furthermore, considering the complex shapes and features that may exist in the new energy electronic control cover, the die should have a corresponding molding structure. For example, for parts with process requirements such as bending and drawing, a reasonable bending die and drawing die structure should be designed. The bending die should consider factors such as bending radius and springback, and determine the angle and size compensation of the die through precise calculation and testing to obtain a bending angle and shape that meets the design requirements. The drawing die should pay attention to the drawing depth, drawing coefficient, etc., and reasonably design structures such as the blank holder to control the flow of the material to prevent wrinkling and cracking.
In addition, the unloading and ejection devices of the die are also critical. The unloading device is used to remove the sheet or waste from the die after the stamping is completed, which is convenient for subsequent operations. The ejector device ejects the electronic control cover from the mold cavity after stamping to ensure that the product can be taken out smoothly and without damage.
Finally, the strength and rigidity design of the mold cannot be ignored. Since it will be subjected to huge impact force during the stamping process, the mold must have sufficient strength and rigidity to resist deformation and damage. In terms of structural design, the overall strength and rigidity of the mold can be improved by increasing the wall thickness of the mold, using high-quality mold materials, and reasonable reinforcement rib layout.
In short, the structural design of the new energy electronic control cover stamping mold needs to comprehensively consider multiple key points, from the cavity to the positioning guide, from the molding structure to the unloading ejection, and then to the strength and rigidity guarantee. Each link is closely connected and affects each other. Only in this way can a high-quality and efficient stamping mold be designed.
