Welding type front axle beam and welding process thereof

Abstract

The invention discloses a welding type front axle beam which is reasonable in structure and is simple in manufacturing process. The welding type front axle beam comprises an upper cover plate, a lower cover plate and a hollow tetragonal structure formed by welding two web plates, wherein the two web plates are arranged between the upper cover plate and the lower cover plate; and welding reserved positions at which the web plates are welded are arranged at the two sides of the upper cover plate and the lower cover plate. A welding process of the welding type front axle beam comprises the following steps of: welding the upper cover plate and the lower cover plate which are formed by being punched with the two web plates in a combined manner and carrying out down welding among the upper cover plate, the lower cover plate and the two web plates at the welding reserved positions; arranging pin seats at the positions of the two ends of the lower cover plate and carrying out down welding on the lower cover plate and the pin seats through welding grooves in the lower ends of the pin seats; forming craters between the two web plates and the pin seats and carrying out down welding at the craters; and carrying out down welding between the upper cover and the pin seats on the upper cover plate. The welding type front axle beam has the advantages of reasonable design, reliable performance, simple manufacturing process, low energy consumption, less environmental pollution and the like, and is suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a welded front axle beam with reasonable structure and convenient manufacture, and at the same time relates to its manufacturing welding process. Background technique [0002] At present, the front axle beams of automobiles in the domestic market are generally processed by casting or forging, and product defects such as cracks and pores are prone to occur during the casting or forging process, resulting in low production capacity, high cost, and large power consumption. , and the casting or forging process is complicated, and the three wastes produced in the process are much, and the environmental pollution is large. Contents of the invention [0003] Aiming at the deficiencies in the prior art above, the present invention aims to provide a welded front axle beam with reasonable structure and convenient manufacture, which has simple manufacturing process and low cost.
