Abstract

The invention discloses a four-step forging forming process for an automobile hub axle tube, and relates to the technical field of forging forming. The four-step forging forming process for the automobile hub axle tube comprises the following steps: S1, raw material pretreatment: selecting a bar with proper length, placing the bar in a heating furnace body for heating, controlling the heating temperature between 350 DEG C and 450 DEG C, and carrying out subsequent primary forging and precision forging; a bar can be cut and ground and then is heated through the heating furnace body, the heated bar is taken out of the heating furnace and placed in the pre-forging die through the transfer device, the bar is subjected to primary forging and forming through hydraulic forging equipment, and precision forging operation is carried out after impurities are removed. The anti-oxidation treatment is carried out on the hub axle tube after the hub axle tube is formed, the forging forming quality of a workpiece is guaranteed, and meanwhile through spraying of the anti-oxidation layer, the anti-oxidation performance of the hub axle tube is improved.

Description

technical field [0001] The invention relates to the technical field of forging forming, in particular to a four-step forging forming process of an automobile hub shaft tube. Background technique [0002] Forging is a processing method that uses forging machinery to exert pressure on metal blanks to cause plastic deformation to obtain forgings with certain mechanical properties, certain shapes and sizes, one of the two major components of forging, forging and stamping; through forging It can eliminate defects such as as-cast looseness produced in the metal smelting process, optimize the microstructure, and at the same time, due to the preservation of complete metal flow lines, the mechanical properties of forgings are generally better than castings of the same material. For important parts with high loads and severe working conditions in related machinery, forgings are mostly used, except for plates, profiles or weldments that can be rolled with simpler shapes. [0003] With...
