Precision metal stamping parts production in several matters needing attention

What is a precision metal stamping parts? We can understand for thickness unchanged in the process of machining parts, sheet metal pieces, is in fact the punching, bending, stretching and other operations can to processing, in precision metal stamping processing we should pay attention to what? Let's have a look. One, with a single process mold to some simple metal stamping parts. With multichannel stamping process complex shape precision metal stamping parts, and the mould structure or strength is limited, its inner and outer contour should be divided into several parts blanking. Higher requirements for the flatness of workpiece, can add again after blanking process leveling process operation. Second, precision metal stamping die structure shape is complex determines the bending parts need how many number of processes, this according to the number of the bending Angle, to determine the relative position and bending direction. Why are sometimes increased after bending shaping process? This is because the bending part of the bending radius is less than the allowable values. Third, when we add finishing process after blanking process or the fine blanking process directly, this is because the quality of workpiece cross section and dimension accuracy requirement is high. Four, for precision metal stamping processing, our goals, with the least, the most simple stamping parts processing, design of the stamping parts to simple shape, reasonable structure, it is advantageous to the stamping operation, not only can improve labor productivity, but also is beneficial to the production of stamping parts processing and mechanization and automation of production. Five, we will according to the state of factory existing modelling ability and stamping equipment to determine the process number. And molding capacity must ensure that the mold processing and assembly accuracy up to standard, not only can increase the working procedure. Six, precision metal stamping parts, material properties, drawing, drawing on the number of steps and the height of the diameter of the drawing, material thickness and other conditions determines the number of deep drawing process, but also to determine the deep drawing process. If drawing a relatively small radius or high dimension accuracy requirement, will be finished in deep drawing and shaping process. Seven, we want to improve the stability of the precision metal stamping process will need to increase the number of working procedure, to ensure the quality of the stampings. Additional positioning technology Kong Chong system, such as bending parts forming technology of increasing deformation reduce Kong Chong cut to transfer area, etc. 【 Relevant recommendation 】 Details: how much do you know the new energy automotive stamping parts? Details: sharing details of stamping processing industry: precision metal stamping parts figure how to draw, please be aware that this several steps
