What should be paid attention to during the process of reproducing Dalian stamping parts

In order to meet the principle of precision stamping process, the number of drawing by drawing process calculation to determine, because it is not only related to the material properties, drawing height, drawing the number of steps and other factors, will also involve the conditions of drawing diameter and thickness.



Since the Dalian stamping to large-scale and complex development, for the stamping quality requirements more stringent, in order to achieve these objectives, stamping parts manufacturers put forward the quality control principle, reflected in the degree of precision, fine and exquisite degree etc.. With the die set and guide the standardization, and the simple die, compound die, progressive die and quick die change device research and development, in the process of stamping production preparation work and preparation time can be effectively reduced and shortened, the advanced stamping technology can be applied to mass production reasonable application in multi variety and small batch production.



The elastic bending of sheet metal can be greatly suppressed if sufficient elastic compression force is applied to the upper and lower parts of the sheet metal during blanking. General blanking die with elastic stripper plate to press, but it is difficult to suppress the elastic deformation of the sheet metal stamping, some roughness has no special requirement to meet.



Stamping production out of the need of stamping equipment, but also the corresponding mold, through the research and improvement of self, not only the service life of the equipment has been significantly improved, stamping out of production, whether the specifications guaranteed or appearance quality, have further improved.



Analysis showed that some defects of stamping are caused by defects of protective devices, so the processing and production of stamping parts, must use the installed protection mode, to avoid in the production process due to small amount of processing, processing personnel skills are not refined, and to have good stamping caused damage.
