Embodiment Construction

[0037] refer to figure 1 , The stamping die of this embodiment includes an upper mold base, a lower mold base 1 and a blank holder 3. For clarity, the upper mold base is omitted in the figure. A punch 2 and a hole-turning punch 6 are installed on the lower mold base 1 . The punch 2 is used to form the main shape of the workpiece, and the hole turning punch 6 is used to realize turning the hole.

[0038] refer to figure 2 , image 3 , the installation base 4 is fixedly installed on the lower mold base 1, and the turning hole punch 6 is fixed on the installation base 4 through the fixing seat 5. The hole turning punch 6 has a mounting portion 61 and a hole turning portion 62 , wherein the mounting portion 61 is used to cooperate with the fixing seat 5 to realize installation, and the hole turning portion 62 is used to realize hole turning. At the top of the hole-turning punch 6, the end of the hole-turning portion 62 is a 1 / 3-circle boss 63, and other parts of the top of th...

Abstract

The invention provides a stamping and molding process of automobile roof covers. In a process of drawing and forming, a flanged hole is formed in a blank line; the flanged hole can be used as a positioning hole in the subsequent process; the position of the flanged hole can be used as waste and cut in the subsequent process. The invention also provides a stamping die. The stamping and molding process of the automobile roof covers can improve the positioning accuracy in the process of stamping and molding the automobile roof covers.

Description

technical field [0001] The invention relates to the stamping field of automobile cover parts, in particular to a stamping forming process and a stamping die of an automobile top cover. Background technique [0002] In terms of stamping technology, compared with other stamping parts, automobile outer covering parts have the characteristics of thinner materials, complex shapes, and mostly three-dimensional curved surfaces, high surface quality and precision requirements, etc. The quality of the outer covering parts will directly affect the appearance of the whole vehicle and quality. [0003] The stamping forming of automobile panels is to determine the sequence of drawing, trimming, punching, flanging, shaping and other processes and the specific content of each process according to the product structure shape and technical requirements. In order to ensure that the parts meet higher precision requirements, there needs to be a unified positioning reference between different p...
