Stamping process of diesel engine fuel tank

Diesel engine fuel tanks are devices for storing fuel oil. The production materials of diesel engine fuel tanks are mainly divided into two types: metal fuel tanks and plastic fuel tanks. Metal fuel tanks are mainly made of iron materials. Diesel engine fuel tanks are divided into many types. The most important thing for any fuel tank is to ensure stable quality and no oil leakage. Therefore, the welding of fuel tanks is also very important. The production of most fuel tanks is This is done by stamping, drawing, and then welding. The general fuel tank is made into a finished product by riveting and welding two to three separate parts. First of all, the first sequence of the fuel tank is punching. The raw material is punched into square or rectangular plates of a specified size. This process can be produced by rolling and slitting and then automatic punching. The second sequence is the most critical forming. Generally speaking, fuel tank forming is a drawing process, so this process is very important. The stability of the mold design and the stability of the machine tool are also guaranteed. The forming process needs to be completed on a hydraulic press and the forming is completed. The second sequence is trimming. This process determines whether a punch or a hydraulic press is based on different fuel tank models. The purpose of trimming is not only to be neat and beautiful, but also to provide a guarantee for welding. Punching and boring of the fuel tank port are generally completed by a punching machine. After all the sub-parts are processed, the next process is welding. First, a ring welder is needed for welding. The welding gun starts to work when the upper and lower sub-parts are clamped together in the fixed fixture. The welding current is very important. The welding is too small, and the current is not static, because the welding machine works for a long time, the temperature rises, even if the cooling equipment is used normally, the current must be adjusted appropriately. These are the operators' own experience in the production process. . After the welding is completed, each fuel tank has to be tested. The method of testing is at atmospheric pressure. Spraying, packaging, and shipping can only be carried out under the condition of ensuring that there is no air leakage. This article is provided by stamping.
