Problems solved by technology

Because the forming process cannot be controlled, there will be uneven surfaces locally on the product surface
On the flanging and shaping die designed by the traditional stamping process, the solution to this quality defect is currently only to minimize the area of ​​the uneven surface, which cannot be fundamentally solved.

Embodiment Construction

[0020] Below in conjunction with accompanying drawing and embodiment, further elaborate the present invention. In the following detailed description, certain exemplary embodiments of the invention are described by way of illustration only. Needless to say, those skilled in the art would realize that the described embodiments can be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0021] Such as figure 1 and figure 2 As shown in the stamping method of the front panel of the automobile, when the drawing process is shaped, the ribs 1 absorbing excess materials are drawn and formed on the plate outside the dashboard panel, and the upward convex direction of the ribs 1 is consistent with the The upward convex direction of the dash panel is consistent, and the ability of the convex rib 1 to absorb e...

Abstract

The invention discloses a method for stamping a dash middle board of an automobile. A convex rib for absorbing excess materials is formed by drawing a board outside the dash middle board; the protrusion direction of the convex rib is the same as that of the dash middle board; the convex rib is used for absorbing the excess materials produced during the stamping process, so that the problem of end wrinkling of a product is solved; meanwhile, the dash middle board is also fully drawn to guarantee high rigidity of the product.

Description

technical field [0001] The invention relates to a method for preventing the wrinkling of the workpiece and ensuring good rigidity of the workpiece when stamping the front panel of the automobile. Background technique [0002] In recent years, my country's automobile industry has been changing with each passing day, but at the same time consumers have higher and higher requirements for the quality of automobiles. As the cover parts of automobiles, stamping parts have higher and higher quality requirements. The dash panel is the outer panel of the automobile panel, and the product quality requirements are of course very high. The traditional stamping process can no longer meet the current requirements. In the traditional stamping process, the two ends are directly extended according to the product during the drawing process. The disadvantage is that the two ends of the product are partially wrinkled due to excess material that cannot be absorbed. Because the mid-panel of the...
