Embodiment Construction

[0045] A method for compensating mold surface over A surface for optimizing the surface quality of vehicle body outer covering parts: comprising the following steps:

[0046] A1. Data measurement and analysis on the surface quality defects of the drawn parts of the body outer panel through precision measuring equipment ( Figure 1-Figure 3 );

[0047] A2. Use precision measuring equipment to measure and analyze the data on the surface A of the drawing die punch for the outer body panel ( Figure 1-Figure 3 );

[0048] A3. By comparing the surface quality defect data of the drawn part of the outer body cover with the data on the A side of the punch of the outer body cover drawing die, confirm the missing state of the A side of the punch of the drawing die of the outer body cover;

[0049]A4. Restore the reference state on the surface A of the drawing die punch of the body outer panel ( Figure 5 middle icon 2);

[0050] A5. Confirm the surface quality defect status of the d...

Abstract

The invention discloses a mold molded surface through A face compensation method for optimizing the surface quality of an outer covering part of a car body. The method comprises the steps of debuggingdata quantization, application of a theoretical color-patch map, development of a debugging process and the like. In the method, the surface quality defects of the outer covering part of the car bodyand the satiation state of the A face of a convex mold of an outer covering part mold of the car body are confirmed through cooperative use of precision measurement equipment, increment compensationis achieved on the A face of the convex mold of the outer covering part mold of the car body is achieved through reasonable use of multiple precision increment compensation means, the grinding methodis standardized to guarantee that the artificially-corrected A face of the convex mold of the outer covering part mold of the car body is full and smooth, and a multi-dimensional control comprehensivedebugging method is carried out so as to guarantee that connected curved faces or curves in the product model of the outer covering part of the car body are smooth. Through innovative fixed-point andoriented trace compensation, the shackle of original stamping and debugging methods is broken, the surface quality of the outer covering part of the car body is effectively improved, the debugging period is compressed, production stability is improved, and the overall attractiveness of the car body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of the surface quality of stamping parts of the outer cover of an automobile body, in particular to a method for compensating the surface of a mold through surface A for optimizing the surface quality of the outer cover of the vehicle body. Background technique [0002] In the industry, the original method of debugging the body outer cover is that the debugger smoothes the surface of the convex model of the body outer cover mold, which destroys the fullness of the surface A of the body outer cover mold punch and seriously affects the surface of the body outer cover. Stability of quality; the pressure control of the post-turning mold is also a reduced grinding pattern, which can only achieve the surface profile of the outer body cover. The original method of debugging the outer body cover can only be to optimize the outer body cover Surface quality defects, the depth size of the surface quality defects of the...
