Problems solved by technology

Although such an approach seems easy to implement, there are many uncertainties, increased work costs, reduced work efficiency, and the bending position is slightly different from the extension of the material itself, so the final forming position will be thousands of miles away. , directly affects the welding process and increases the scrap rate of the product

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as Figure 3-4 As shown, an all-aluminum fuel tank, which is rectangular, is characterized in that it includes an upper tank 1 and a lower tank 2, and the upper tank 1 and the lower tank 2 are matched and connected. The upper box body 1 includes a cover plate 11 and a lower flange 12, the cover plate 11 and the lower flange 12 are vertically and seamlessly connected, and the connection is smoothly transitioned. The cover plate 11 is provided with mounting holes. The lower box body 2 includes a bottom plate 21 and an upper flange 22 , the bottom plate 21 and the upper flange 22 are vertically and seamlessly connected, and the connection is smoothly transitioned. The upper box body 1 is U-shaped with an opening downward, and the lower box body 2 is U-shaped with an upward opening.

Abstract

The invention relates to a full-aluminum fuel tank and a manufacturing method thereof. The full-aluminum fuel tank is rectangular and comprises an upper tank body and a lower tank body which are connected in a matched manner. The upper tank body comprises a cover plate and a lower folding edge. The cover plate is provided with mounting holes. The lower tank body comprises a bottom plate and an upper folding edge. The manufacturing method includes the steps of firstly, independently cutting plates needed by the upper tank body and the lower tank body according to fuel tank capacity; secondly, using a flanging die to perform flanging on the cut plates to allow the cover plate of the upper tank body to be vertical to the lower folding edge and the bottom plate of the lower tank body to be vertical to the upper folding edge; thirdly, using a die to punch the mounting holes in the cover plate; performing weld joint connection on the upper tank body and the lower tank body. Compared with the prior art, the full-aluminum fuel tank is reasonable in structural design, simple in structure, high in work efficiency, good in size consistency, suitable for large-batch production, high in machining precision and stable in machining quality.

Description

technical field [0001] The invention relates to a fuel tank, in particular to an all-aluminum fuel tank for automobiles and a manufacturing method thereof. Background technique [0002] In the production of automotive all-aluminum fuel tanks, the leakage rate of fuel tanks and the success rate of one-time welding are two important indicators to measure the quality of fuel tank products. The leakage of the fuel tank often occurs at the welded joint between the fuel tank body and the fuel tank end cover. The fuel tank joint is often regarded as a key process in the production process of the fuel tank. Manufacturers often search for the cause repeatedly in this process, but in the fuel tank The process of flanging the cabinet before seaming and forming is often not paid attention to. The flatness of the cabinet after flanging and the uniformity of the surrounding dimensions after flanging often affect the quality of the seaming and forming. [0003] At present, individual fuel...
