Embodiment

[0025] The present invention is a kind of processing method of automobile crash box, such as Figure 1 to Figure 2 As shown, the car crash box is made of sheet metal, and the cantilever 1 and the box body 2 of the car crash box are formed by welding the sheet metal parts. The processing method of the car crash box includes the following steps: The stamping process of the station produces various sheet metal parts: the cantilever 1, and the cover plate 3, the upper cover 4 and the lower cover 5 that form the box body 2, wherein the upper cover 4 and the lower cover 5 are both wavy curved surfaces and There are flanges on both sides. The cantilever 1 includes an L-shaped cover part 11 and a cantilever part 12, wherein the cover part 11 is provided with a flange and is welded with the box body 2. The cantilever part is provided with a supporting flange 13 to support The flange 13 is fixedly connected with the cover part 11; b) welding the nut 6 to the cover 3; c) welding the cove...

Abstract

The invention discloses a processing method of an automobile collision box. The automobile collision box is made of a sheet metal serving as a raw material; a cantilever and a box body of the automobile collision box are formed by welding the sheet metal. The processing method of the automobile collision box comprises the following steps: (a) performing multi-station stamping processing through a progressive die to obtain each sheet metal: the cantilever, and cover plates, an upper cover and a lower cover which form the box body, wherein the upper cover and the lower cover have wavy curved surfaces and provided with flanges on both sides; (b) welding nuts on the cover plates; (c) welding the cover plates, the upper cover and the lower cover to form the box body with a cross section like a hollow square; (d) welding the box body and the cantilever. The automobile collision box processed can meet the requirements on the intensity and the impact resistance performance, and the weight cannot be increased; the procedure is simplified, the automation degree is high, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to an automobile crash box, in particular to a processing method of the automobile crash box. Background technique [0002] The crash box is installed between the front beam (or rear beam) and the bumper, which can reduce the impact of the car collision and play the role of the first buffer. When the collision occurs, the crash box will collapse to achieve the purpose of energy absorption. [0003] However, at present, some crash boxes have the disadvantage of poor shock absorption capacity. In order to improve the shock absorption capacity, if the steel plate is thickened, it will lead to an increase in weight and cost; if aluminum alloy is used to reduce weight, it will lead to an increase in cost. . [0004] Therefore, it is necessary to consider the structure, in the case of increasing the rigidity and strength performance requirements, without increasing the thickness of the sheet metal. Therefore, the structure of the cras...
