  • Precision drawing stamping parts
The surface of precision drawing stamping parts 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 cylinder wall generally has the phenomenon that the upper part is thicker and the lower part is thinner. The precision drawing stamping parts processing manufacturer proposes to pay attention to the dimensions on the drawing part design drawings. The tensile parts are different due to the different stress levels. Change the thickness of the material after stretching. 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. The standard method of drawing product size: When designing a drawing product, the size on the product drawing should clearly indicate that the external 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 ±. The essence of safe production of precision drawing stamping parts processing: 1. Protecting the life safety and occupational health of drawing parts laborers is the most fundamental and profound connotation of drawing parts safety production, and is the core of the essence of drawing parts safe production. 2. The safety production of the maximum protection of stretch parts is highlighted. 3. Highlight the protection in the process of producing stretched parts. 4. The production protection of stretched parts under certain historical conditions is highlighted. Production safety in the processing industry of precision drawing stamping parts: Definition of production safety in the processing of precision drawing stamping parts: Refers to the corresponding accident prevention and prevention measures in the activities of producing and operating drawing parts in order to avoid accidents that cause personal injury and property loss Control measures to ensure the personal safety of employees and ensure the smooth progress of the production and operation of stretch parts.
