Problems solved by technology

The existing technical problem is that the steel plate blank is rectangular, and the excess material needs to be removed when forming the part, resulting in a lot of waste, low material utilization rate, and high cost
At the same time, the rectangular material needs to be cut horizontally from the steel coil first, and then the required parts are made into the required parts through single blanking and fine blanking. The manufacturing method has more processes and higher cost

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] see figure 1 , the existing lower inner skin of the side wall of the automobile has an irregular polygonal shape when developed, the left and right sides are vertically parallel, the lower side is a circular arc, and the upper side is four continuously bent sides. The developed shape of the final product of the present invention is similar to it.

[0018] see figure 2 , image 3 A kind of steel plate blank of the rear lower inner skin of the car side wall shown, the two sides 9-11 of the bottom of its body are all straight, and the middle part 9-12 is a notch, and the notch 9-12 of the body is in line with the car. Corresponds to the notch 10-1 on the lower side of the rear lower inner skin development surface of the side wall; the left side 9-2 and right side 9-3 of the main body 9 are parallel to each other; the upper side of the main body 9 is a continuous...

Abstract

The invention discloses a steel plate blank of a rear lower inner skin of a vehicle side body, wherein both the left part and the right part of the lower edge of a steel plate blank main body are flat, the middle part of the lower edge of the steel plat blank main body is circularly bent, and the lower edge of the main body corresponds to the arch of the lower edge of the unfolding shape of the rear lower inner skin of the vehicle side body; both the left edge and the right edge of the main body are vertical, and are respectively parallel with the left edge and the right edge of the unfolding shape of the rear lower skin of the vehicle side body; and the upper edge of the main body is formed by four edges which are continuously bent from left to right, and the four edges are respectively parallel with the upper edge of the unfolding shape of the rear lower inner skin of the vehicle side body. Because the steel plate blank is similar to the shape of the required part, scraps which are produced after a part is finally formed are fewer, so the material utilization rate can be improved, and the cost is reduced. Compared with a method utilizing a rectangular blank to manufacture, a subsequent step of separately discharging the single rectangular blank is omitted, the manufacturing processes and control links can be reduced, the cost is further saved, and the precision and the quality of the final part are improved.

Description

technical field [0001] The invention relates to automobile parts, in particular to a steel plate blank for the rear lower inner skin of the side wall of the automobile. Background technique [0002] With the increasingly prominent contradiction between the development of the automobile industry and the limited nature of natural resources, people pay more and more attention to the utilization rate of auto parts materials. Improving the utilization rate of materials has become an important means for the automobile industry to reduce costs and promote energy conservation and environmental protection. The unfolded shape of the existing lower inner skin part of the side wall of the automobile is an irregular polygon, the left and right sides are vertically parallel, the lower side is an arc, and the upper side is four continuously bent sides. The existing automobile side wall and rear lower inner skin steel plate blank is a rectangular material. During manufacture, the steel coil...
