Problems solved by technology

[0003] The object of the present invention is to provide an aluminum fuel tank and its production method to improve the unreasonable structure of the existing fuel tank. Most of the partitions are installed by manual welding. There are many welding spots on the partitions, and the welding workload is very large. Poor welding is prone to occur, leading to technical problems such as a high rate of defective production of fuel tanks

Abstract

The invention discloses a novel aluminum fuel tank and a method for producing the same. The novel aluminum fuel tank comprises a body A, bodies B, end covers C and partition plates D. The method for producing the novel aluminum fuel tank includes working procedures of forming the body A; forming the bodies B; forming the partition plates; carrying out press-fitting on the partition plates; welding the bodies; welding the end covers and the like. The novel aluminum fuel tank and the method have the advantages that the bodies B are symmetrically arranged on two sides of the body A, two ends of each body B are respectively subjected to connection and supporting by the aid of the end covers and the partition plates, and accordingly excellent shaping and fixing effects can be realized; the partition plates are subjected to press-fitting in the bodies B by the aid of a special press-fitting machine after the body A and the bodies B are respectively formed, and accordingly shortcomings of long operation time, large quantities of welding spots, high experience requirements on operators, easiness in causing poor welding and the like due to the fact that existing partition plates are subjected to manual spot welding can be overcome; the section, where the corresponding partition plate is arranged by means of press-fitting, of each body B is inserted in an end of the body A, then the bodies are welded to obtain the novel aluminum fuel tank, accordingly, the production takt can be greatly improved, the press-fitting work takt for the partition plates of the novel aluminum fuel tank can be shortened and is within 20 seconds from the original 100 seconds, the production efficiency can be improved, and the production cost can be saved.

Description

technical field [0001] The invention relates to a fuel tank, in particular to an aluminum fuel tank and a production method thereof. Background technique [0002] Aluminum fuel tanks for automobiles have the characteristics of lightness, corrosion resistance and long service life. They are gradually replacing iron fuel tanks, and their market share is increasing. During the operation of the vehicle, bumps and slopes are unavoidable, the oil in the fuel tank will fluctuate greatly, and the sloshing of fuel will also produce a lot of noise. In order to reduce the buffer and improve the strength of the fuel tank, there is generally a Two partitions. At present, during the production of fuel tanks, the partitions are installed by spot welding, and the partitions are welded to the inner wall of the fuel tank. A partition has dozens of welding spots. On average, the welding of a fuel tank takes 8-10 minutes, and the welding is manual. Operation, the welding quality is not stable...
