Automobile left and right fender stamping technology and automobile left and right fender drawing die

Abstract

The invention discloses an automobile left and right fender stamping technology and an automobile left and right fender drawing die. The technology includes the following steps that firstly, blank layout and blanking are performed, wherein blank layout and blanking are performed according to the size of a single-side fender of an automobile, and a left fender and a right fender are arranged on two blanks in a separated mode; secondly, drawing is performed, wherein the blanks of the left fender and the right fender are positioned in a separated mode, and meanwhile drawing is performed on the same drawing die; thirdly, trimming is performed, wherein the periphery of the blank of the left fender and the periphery of the blank of the right fender are trimmed, and the left fender and the right fender are formed. A male die, a female die and a material pressing ring of the die are of left-portion and right portion structures, and the left-portion and right-portion structures are installed on the same upper template and the same lower template. According to the automobile left and right fender stamping technology and the automobile left and right fender drawing die, the left fender and the right fender are stamped on the two blanks in the separated mode, so that a more flexible blank layout manner of the blanks can be achieved on panel veneer. Thus, production of waste materials is reduced, the utilization rate of materials is improved, production cost is greatly reduced, sequential steps of cutting and separating the left fender and the right fender are removed, and production efficiency is improved.

Description

technical field [0001] The invention relates to automobile manufacturing technology, in particular to a stamping process for left and right fenders of automobiles and a drawing die thereof. Background technique [0002] The fender is the outer panel of the car body that covers the left and right symmetry of the wheel. There are two traditional methods for forming the fender of the car: the first method is to use two blanks to separate the left fender and the right fender in two sets. Separate molding on the mold, this method produces a product with a set of molds, the production efficiency is low, the cost is high, and it is basically not used now; the second method is the split molding process method, which is to share the left fender and the right Sheet blanks are formed on a set of molds. This method has high production efficiency. One set of molds produces two products. It is the most widely used fender forming method at present, but this method, the sheet Blank 10 is n...

[0002] The fender is the outer panel of the car body that covers the left and right symmetry of the wheel. There are two traditional methods for forming the fender of the car: the first method is to use two blanks to separate the left fender and the right fender in two sets. Separate molding on the mold, this method produces a product with a set of molds, the production efficiency is low, the cost is high, and it is basically not used now; the second method is the split molding process method, which is to share the left fender and the right Sheet blanks are formed on a set of molds. This method has high production efficiency. One set of molds produces two products. It is the most widely used fender forming method at present, but this method, the sheet Blank 10 is not easy to layout, the layout method is as follows figure 1 As shown, there are more waste materials generated by nesting, which makes the material utilization rate low and is not conducive to cost saving
