Problems solved by technology
This has caused the technical quality of mold design to be uneven. Therefore, for molds with poor mold design technology, the parts are broken and wrinkled during the mold trial. No matter how the fitter adjusts and polishes the broken part of the mold, there is no effect. The fitter can only repeatedly grind and increase the convex circle of the mold, and even double the formed convex fillet
It is time-consuming and laborious to manufacture and debug molds in this way. For example, the upper mold is ground and the fitter needs to lie on his back on the machine mold.
This operation has seriously affected the safety and health of the fitter, especially the most serious damage to the eyes.

Embodiment
[0017] Example: see figure 1 .
[0018] An explanatory drawing board for the empirical formula of the die drawing forming process of an automobile panel, the main body is a rectangular drawing board body, and the drawing board body is divided into a diagram area, a concave / convex die radius corresponding coefficient area, and a drawing area from top to bottom. Rib height corresponding coefficient area, drawing forming process experience formula area.
[0019] see figure 1 , the uppermost part of the rectangular diagram board body is the diagram area, where R is the radius of the corner, R1 and R2 are the radii of the die and punch respectively, and the unit is mm. The ratio of different R1\R2 is shown below the diagram area. The empirical coefficient r 1 * r 2 .
[0020] The design of drawing dies for conventional automobile panels requires supplementary design of the process outside the product, that is, the part outside the trimming line. In order to make the part have ...

The invention relates to the field of assistant tools for automobile product design, sheet metal forming technology and die making design, particular to an empirical formula illustration plate for the automobile covering part die drawing formation technology. The subject of the empirical formula illustration plate for the automobile covering part die drawing formation technology is a rectangular illustration plate main body, and the illustration plate main body is divided into an illustration region, a concave / convex die radius correspondence coefficient region, a drawing rib height correspondence coefficient region and a drawing formation technology empirical formula region. Complex empirical formulas are simplified and are integrated on one illustration plate which is convenient for carrying and practical. The illustration plate is designed into a transparent plate and can be made into the ordinary plastic thin plate, and low cost is required for large-scale production. The side edge of the plate is provided with a graduated scale, so that one plate has multiple purposes.
Description
technical field [0001] The invention relates to the field of auxiliary tools for automobile product design, stamping process design and mold manufacturing design, and specifically relates to an explanatory drawing board for experiential formulas of drawing forming process of automobile panel dies. Background technique [0002] The empirical formula for drawing forming of automobile panel parts is a world-class research topic, and it is a technical tool for analyzing and demonstrating the technical feasibility of automobile product design, stamping process design and mold manufacturing design. [0003] In the process of automotive drawing die design, different designers of the same product have different die structures, because there is no clear theoretical technical standard for product design, stamping process design and die design. Even the most advanced computer software CAE analysis result in the world is still an inaccurate and vague answer, which brings great confusion...
