Embodiment 1

[0026] A positioning stamping processing method for high-strength steel plate parts, characterized in that it comprises the following steps:

[0027] S1. Production of positioning pipe: select the pipe and apply the anti-corrosion paint evenly on the inner wall of the pipe to make a positioning pipe (the thickness of the anti-corrosion paint is 0.22mm);

[0028] S2. Positioning tube welding: welding the positioning tube to the position of the steel plate to be drilled;

[0029] S3. Pour the corrosive solution: pour the corrosive solution into the positioning tube (the corrosive solution is a mixed solution of 95% hydrochloric acid and 90% nitric acid at a ratio of 3:1);

[0030] S4. Cooling down: cooling the surface of the positioning tube to reduce the surface temperature of the positioning tube to -10°C (to speed up the corrosion rate of the corrosive liquid on the steel plate).

[0031] S5, drilling: the drill bit of the drilling device is passed through the positioning pi...

Abstract

The invention discloses a positioning and stamping processing method for high-strength steel plate parts. The positioning and stamping processing method comprises the following steps that a pipe material is selected, anticorrosive paint is uniformly coated to the inner wall of the pipe material, and a positioning pipe is accordingly manufactured; the positioning pipe is welded to the to-be-drilledposition of a steel plate, corrosive liquid is poured into the positioning pipe, the surface of the positioning pipe is cooled, and the surface temperature of the positioning pipe is lowered to -15 DEG C-0 DEG C (so as to speed up the corrosion rate of the corrosive liquid on the steel plate); and a drill bit of a drilling device penetrates through the positioning pipe to drill the steel plate, the single-time effective drilling time is 1 minute at most, the drill bit is cleaned after drilling operation is completed each time, and the operation is lasted until the difference between the drilling radius and the radius of the positioning pipe is less than 0.5 mm. By means of the method, the manners that the positioning pipe is welded and the to-be-drilled position of the steel plate is corroded are adopted for positioning operation, positioning deviations caused by the excessive hardness of stamping materials are avoided, the difficulty of the positioning operation is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical production, in particular to a positioning stamping processing method for high-strength steel plate parts. Background technique [0002] In the process of mechanized production, in order to ensure the efficiency of production, it is often necessary to use stamping parts to perform stamping operations on products. Stamping parts rely on presses and molds to apply external forces to plates, strips, pipes, and profiles to produce plastic deformation or Separation, so as to obtain the required shape and size of the workpiece (stamping) forming processing method. Stamping and forging both belong to plastic processing (or pressure processing), and are collectively called forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. [0003] The traditional positioning stamping processing method is prone to positioning deviation caused by excessive hardness of the st...
