Stamping parts processing factory talk about the number and order of stamping parts processing

The number of stamping parts processing refers to the number of times the process of the same nature is repeated. For drawing stamping parts, the number of drawing can be calculated according to its shape and size, as well as the allowable degree of deformation of the sheet material. Others such as bending stamping parts, The number of stamping of flanging parts is also determined according to the specific shape and size and the degree of limit deformation; the arrangement of the processing sequence of stamping parts should be conducive to the plasticity of the material to reduce the number of processes, mainly according to the deformation characteristics and quality requirements of the process The general principles for arranging and determining the stamping sequence are as follows: 1. For flat parts with holes or gaps, if a simple die is selected, the material should be blanked first. When a continuous die is used for punching or notching, it should be punched or punched first. Incision, blanking after 2. For curved parts with holes, the distance between the edge of the hole and the bending area is relatively large, and the hole can be punched first and then bend. For example, when the edge of the hole is near the bending area or the hole and the reference plane have higher requirements, It must be bent first and then punched; 3. For deep drawn parts with holes, they are generally drawn first and then punched, but the position of the hole is at the bottom of the part and the hole size requirement is not high, it can also be punched on the blank first. 4. For multi-angle bending parts, the order of arrangement should be considered from the two aspects of material deformation and material movement during bending. Generally, the outer corners are bent first, and the inner corners are bent later; 5. For drawn parts with complex shapes, To facilitate material deformation and flow, the inner shape should be formed first, and then the outer shape should be deepened; 6. The shaping or leveling process should be carried out after the metal stamping parts are basically formed; Recommended article: The effect of hydroforming technology on stamping parts : The quantity of metal stamping parts to be produced should be determined according to the actual situation
