How to choose stamping equipment for metal automobile stamping parts?

The stamping equipment for fabrication hardware automobile stamping parts mainly includes two aspects: selecting the type of press and determining the specifications of the press; the selection of equipment type; there are many types of metal stamping equipment, and their rigidity, precision and use are different. If they are not the same, they should be selected correctly according to the nature of the stamping process, the production batch, the size of the mold, and the accuracy of the parts;

  • 1. For the production of small and medium-sized metal stamping parts, bending parts or deep drawing parts, open mechanical presses should be used. Although the rigidity of open presses is poor, the deformation of the bed under the action of stamping force can destroy the blanking. The gap distribution of the die reduces the life of the die or the surface quality of the blanking parts, but because it provides extremely convenient conditions for operation and easy installation of mechanized attachments, it has become the main form of small and medium-sized stamping equipment at present;
  • 2. For the production of large and medium-sized blanking parts, mechanical presses with a closed structure are mostly used. Among them, there are general-purpose presses, and there are also professional extrusion presses and precision presses with small table tops and high rigidity. In the production of large-scale metal deep-drawing stamping parts, the double-action deep-drawing press should be used as much as possible, because the mold structure used is simple and easy to adjust;
  • 3. In small batch production, especially in the production of large and thick plate metal stamping parts, hydraulic presses are mostly used. The hydraulic press has no fixed stroke, will not be overloaded due to changes in the thickness of the sheet, and has obvious advantages compared with mechanical presses when a large force stroke is required for fabrication. However, the speed of the hydraulic press is slow, the productivity is low, and the dimensional accuracy of the parts is sometimes not very stable due to the influence of operating factors.
  • 4. The friction press has the characteristics of simple structure, low cost, and is not prone to overload damage, so it is often used to complete stamping work such as bending and forming in small batch production. However, the number of strokes per unit time of the friction press is small, the productivity is low, and the operation is not very convenient. In mass production or mass production with complex shapes, high-speed presses or multi-station automatic presses should be used as far as possible.
