The surface of precision drawing stamping parts for car chargers does not have the defects of die casting parts. The shape of the stretched part should be simple and symmetrical, the mouth should be allowed to rebound slightly, and the side wall should be allowed to have a technological slope. The wall thickness of the wall part of the cylinder generally has the phenomenon of being thick at the top and thin at the bottom. The shape of the precision drawing stamping car charger should be simple and symmetrical, the mouth should be allowed to rebound slightly, and the side wall should be allowed to have a technological slope. The wall thickness of the wall part of the cylinder generally has the phenomenon of being thick at the top and thin at the bottom. Hardware tensile parts processing manufacturers propose to pay attention to the dimensions on the design drawings of the tensile parts. Due to the different stresses on the tensile parts, the thickness of the material after stretching changes. Generally speaking, the center of the bottom maintains the original thickness, the material at the bottom rounded corners becomes thinner, the material at the top near the flange becomes thicker, and the material at the rounded corners around the rectangular stretched piece becomes thicker. Standard method for product dimensions of precision stretched parts: When designing stretched products, the dimensions on the product drawing should clearly indicate that the external dimensions or internal dimensions must be guaranteed, and the internal and external dimensions cannot be marked at the same time. Marking method of drawing part dimensional tolerance: the inner radius of the concave-convex arc of the drawing part and the height dimensional tolerance of the once-formed cylindrical drawing part are the double-sided symmetrical deviation, and the deviation value is the national standard (GB) 16 accuracy standard Half of the difference, and prefixed with ±.
