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.
