The production process of gear blank usually includes the following steps: Material selection: According to the use requirements of the gear and the working environment, choose the appropriate material. Common gear materials include steel, cast iron, aluminum alloy and so on. Material cutting: The selected material is cut according to the specifications to obtain the suitable size of the gear blank. Heat treatment: Heat treatment of gear blanks, usually including quenching and tempering two processes. Quenching can increase the hardness and strength of the gear, tempering can reduce the brittleness of the gear, improve its toughness and toughening properties. Roughing: The gear die blank after heat treatment is roughed, including turning, milling, drilling and other operations to obtain the basic shape and size of the gear. Gear machining: According to the design requirements, gear machining is carried out on the gear die blank. Gear machining usually includes milling, hobbing, grinding and other processes to obtain accurate meshing shape and meshing performance. Machining accuracy test: The precision test of the finished gear die blank, including the parameters of tooth profile error, meshing degree, tooth spacing, etc., to ensure that it meets the design requirements. Surface treatment: The surface treatment of the gear mold is carried out to improve the corrosion resistance and appearance quality. Common surface treatment methods include galvanizing, painting, electroplating, etc. Final inspection and finishing: The final comprehensive inspection of the gear mold is carried out to ensure that the quality meets the requirements. At the same time cleaning, grinding and other finishing work, make the gear mold more smooth and beautiful. It should be noted that the production process of gear blanks may vary due to actual needs and material characteristics, and the above steps are only the production process under general circumstances. In practical application, it is necessary to optimize and adjust the process according to the specific situation.
