Description

Technical Field

[0001] The invention relates to the technical field of axle housing stamping, in particular to a device for removing oxide scale in the process of axle housing stamping. Background Art

[0002] The axle housing is the base for installing the main reducer, differential, half-axle and wheel assembly. Its main function is to support and protect the main reducer, differential and half-axle. Generally speaking, the axle housing of an ordinary non-disconnecting drive axle is a rigid hollow beam supported on the left and right drive wheels. The main reducer, differential, half-axle and other transmission parts are installed in it. The axle housing is connected to the frame or carriage through a longitudinal leaf spring. It is an important part of the drive axle and one of the main components of the running system. The drive axle housing should have sufficient strength and rigidity, small mass, and be easy to disassemble and adjust the main reducer. At present, the production methods of axle housing include integral casting and steel plate stamping and welding. The steel plate stamping and welding axle housing has the advantages of small mass, easy manufacturing, reasonable material utilization, good impact resistance and low cost, and is widely used in passenger cars and commercial vehicles with small loading mass.

[0003] Oxide scale is a corrosion product formed by oxidation of steel at high temperature. Oxide scale is brittle and has no ductility. It is easy to crack and detach under mechanical action and thermal processing. In the stamping process of steel plates in bridge shell production, the formation of oxide scale is more obvious. On the original oxide scale, there are always cracks deep into the matrix. If it is not treated in time, when the electrolyte flows into the crack, iron and oxide scale form a galvanic cell. The oxide scale is the cathode and the iron is the anode to accelerate corrosion. Therefore, the larger the area of ​​the oxide scale, the faster the corrosion rate of the stamped bridge shell matrix and the more serious the corrosion. At the same time, the oxide scale makes the surface of the forging rough. During forging, if the oxide scale is pressed into the forging, it will become a waste in serious cases. At the same time, the oxide scale has a high hardness. During forging, it not only increases the consumption of deformation energy, but also accelerates the wear of the forging die and reduces the service life. Therefore, it is very necessary to develop a quick oxide scale removal device. Summary of the invention
