Problems solved by technology
However, for parts with large surface transitions, such as the convex hull and the outer edge of the shift escutcheon, if the process of one-time drawing and forming is still used, the material shortage in this part will seriously cause the parts to crack during the drawing process, and cannot be finished. Carry out cold stamping production of this product

The invention provides a gear-shifting hole cover drawing process and dies and relates to the technical field of vehicle part machining. The gear-shifting hole cover drawing process provided by the invention includes a preliminary drawing step and a reverse-drawing step, wherein during the preliminary drawing step, a to-be-machined plate is subjected to preliminary drawing through a preliminary drawing die, and thus a convex hull is formed on the to-be-machined plate; and during the reverse-drawing step, the to-be-machined plate is subjected to reverse drawing through a reverse-drawing die, and thus an outer edge is formed on the to-be-machined plate. The gear-shifting hole cover drawing process provided by the invention includes the preliminary drawing step and the reverse-drawing step, the convex hull and the outer edge of a gear-shifting hole cover can be formed separately, the situation that the to-be-machined plate is excessively deformed and cracked during drawing every time is avoided, and the quality of finished products is effectively guaranteed.
Description
technical field [0001] The invention relates to the technical field of vehicle parts processing, in particular to a shift escutcheon drawing process and a mold. Background technique [0002] The cab is an important part of the body of trucks and special vehicles, and it is the place where professional drivers work day and night. Its structure is directly related to the driver's safety, work efficiency and health. The cab generally adopts a metal thin shell structure, which is welded by many parts. The truck shift escutcheon is an important auxiliary part of the gear lever installation part, and it changes according to the shape of the gear lever. [0003] The traditional shift escutcheon is formed by one-time drawing, and then trimmed, punched and flanged. However, for parts with large surface transitions, such as the convex hull and the outer edge of the shift escutcheon, if the process of one-time drawing and forming is still used, the material shortage in this part will...
