A kind of mold processing method

Abstract

The invention discloses a die finishing method. The method comprises the following steps: roughly finishing the bottom surface and the structural surface of a die; semi-finishing the profile of the die; performing quenching process treatment on the die; detecting the hardness of the quenched die, and judging whether the hardness is up to the standard hardness value, if so, detecting the deformation of the profile, and finely finishing the bottom surface and the structural surface according to the deformation of the profile; finely finishing the profile according to a preset design requirement; and performing the bench worker research on the finely-finished die in reference to the standard size design requirement of the die. Through the adoption of the die finishing method, the die numerical control finishing quality can be effectively improved, the workload of a bench worker is reduced, the manufacturing quality of an automobile outer panel die is improved, and the development period of the automobile die is shortened.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a mold processing method. Background technique [0002] In the process of mold making, especially for drawing molds, the manufacturing process is: [0003] Process the bottom surface and structural surface of the mold; process the surface of the mold; the fitter performs preliminary processing; the mold is subjected to quenching process; the fitter performs finishing adjustment. [0004] In the above steps, after the drawing die is finished by the CNC machine tool, it is transferred to the fitter for research and adjustment, and the fitter adjusts the gap between the convex and concave dies of the die with the help of the research and fit press, and quenches it after adjusting to a reasonable state; The quenching process causes the internal stress of the mold itself to change, resulting in deformation of the mold. Among them, the maximum warpage of the bottom surface of the up...
