Gap size and uniformity
Drawing, bending, flanging and other sheet metal forming parts generally need to be blanking (blanking) out of the flat plate to develop the blank. Dongguan CNC processing plant also has blanking and cutting after forming to get a single finished stamping part. Therefore, blanking operation, including common punching, cutting, trimming, etc., Dongguan CNC processing plant is necessary for each kind of sheet metal stamping parts. Therefore, the blanking clearance has a decisive influence on the overall dimension accuracy of the blanking parts. The blanking gap is small and uniform, which can make the blanking dimension obtain higher accuracy. For deep drawing, bending and other forming dies in Dongguan NC machining plant, the large gap will increase the dimension error and springback of the punch. The uneven gap will increase the burr of punch and lead to uneven wear of cutting edge.
Elastic deformation of stamping equipment
In the stamping process of Dongguan CNC plant, the punch will produce certain elastic deformation after loading. Although this kind of deformation changes according to the size of the stamping force and has obvious directionality, Dongguan CNC processing plant mainly punches the stamping parts with the characteristics of volume stamping, such as embossing, embossing, leveling, embossing, wave forming, punching, upsetting, flanging, upsetting, flattening, thinning and deep drawing, which has a significant impact on the dimensional accuracy of stamping.
