Vehicle-mounted aluminum alloy tank production process

Abstract

The invention discloses a vehicle-mounted aluminum alloy tank production process. The vehicle-mounted aluminum alloy tank production process includes the following steps of firstly, barrel plate machining, secondly, separation plate and end socket machining, thirdly, locating, hoisting and transferring, fourthly, tank wrapping and forming, fifthly, longitudinal seam shaping and longitudinal seam welding, sixthly, inner annular seam welding and seventhly, outer annular seam welding. For the feature of tank body machining, the process is designed into a manufacturing method facilitating mechanical line production, and manufacturing accuracy and efficiency can be improved greatly. Through multiple years of experiment practice and summarization, in the process, the edges of two end sockets of a straight-cylinder tank body are milled into the straight edges so that the edges can be matched with the milled straight edges of the tank body so as to guarantee that the edges of the end sockets is in tight butt joint with the edges of the tank body, and single-face welding and double-face forming are conducted through tig side face welding, so that the pass rate of flaw detection reaches 100%; and the reducing part of the middle portion of the reducing tank body is shaped through a die, the edges are milled so as to be in tight butt joint with the tank body, and the pass rate of flaw detection reaches 100% by conducting single-face welding and double-face forming through tig side face welding.

Description

technical field [0001] The invention relates to a method for making a large tank, in particular to a production process for a vehicle-mounted aluminum alloy tank. Background technique [0002] At present, most manufacturers are still using the old technology to make tanks. The production cost of the old technology is high, and the labor cost of a tank is 20,000 to 50,000; the pass rate of flaw detection is extremely low, only less than 60%; the old technology works manually for one weld. , Due to physical and energy reasons, there are no less than 200 pauses in the middle. Therefore, welding defects caused by changes in cold and heat of nodes are fatal to the welding quality of the tank. Contents of the invention [0003] The purpose of the present invention is to provide a production process for vehicle-mounted aluminum alloy tanks, which is used to replace the old production process, and is easy to adopt mechanized flow operation, and its efficiency is three to five time...
