Six principles for the production of precision stamping parts

1) The principle of exquisiteness When the section quality and dimensional accuracy of precision stamping parts are high, you can consider adding a trimming process after the punching process or directly adopting the precision blanking process to ensure that the products produced are exquisite that can withstand the test Products, can be regarded as the medium-precision title of precision stamping parts! 2) The principle of fineness The number of processes for bending parts mainly depends on the complexity of its structure and shape, and is determined by the number of bending angles, relative positions and bending directions. When the bending radius of the bending part is less than the allowable value, a shaping process is added after bending to ensure that it meets or even exceeds the industry standard with fine requirements! 3) Precision principle The number of processes for drawing parts is related to the material properties, drawing height, number of drawing steps, drawing diameter, material thickness and other conditions. It needs to be determined by drawing process calculations. All parameters must be considered. The calculation must be accurate, and the precision calculation and precision production of precision stamping parts can be achieved! When the rounded corner radius of the drawn part is small or the dimensional accuracy is required to be high, it is necessary to add a shaping process after drawing. 4) The principle of precision. The determination of the number of processes should also conform to the company's existing mold making capabilities and the status of stamping equipment. The mold making ability should be able to ensure the corresponding increase in mold processing and assembly accuracy. Otherwise, we can only increase the number of processes, and use an accurate budget to make a preliminary estimate of production, and reduce or even eliminate the waste of large production materials! 5) The principle of high-quality goods In order to improve the stability of the stamping process, it is sometimes necessary to increase the number of processes to ensure the quality of stamping parts. For example, the additional positioning process hole punching of bending parts, the increase of deformation in the forming process, the reduction of hole punching to transfer the deformation zone, etc., not only to be exquisite, but also to maintain the exquisiteness, so that each product is a high-quality product 6) The principle of precision is to blank the workpiece with a simple shape and complete it with a single-process mold. For workpieces with complex shapes, the inner and outer contours of the mold should be divided into several parts due to the restriction of the structure or strength of the mold, which requires multiple stamping processes. When necessary, a continuous die can be selected. For workpieces with high flatness requirements, a leveling process can be added after the punching process, and the characteristics of each product can be accurate to the production process, so that each process is meaningful and effective!
