The invention relates to the technical field of automobile rear axle shafts, and particularly relates to an automobile rear axle shaft tube flaring die. The automobile rear axle shaft tube flaring diecomprises an L-shaped base, wherein a guide groove is formed in the side wall of the base; a guide block is slidably installed in the guide groove; a stamping block is fixedly connected to the guideblock; guide tubes are fixedly connected to the two side walls of the stamping block; a stand column is vertically and fixedly connected to the bottom of the base; the top end of the stand column is inserted into the guide tubes; a nut seat is connected to the stand column in a screwed mode; a notch is formed in the nut seat; a through hole is formed in the side wall of the notch; and a guide rodis inserted into the through hole. In the flaring process of a shaft tube, the guide groove is matched with the guide block, the guide tubes are matched with the stand column, thus the stroke direction of the stamping block is guided, the situation that the stamping block deviates, and consequently the shaft tube is stressed unevenly is prevented, a guide wheel abuts against the flaring position of the shaft tube to centralize the shaft tube, and the situation that the shaft tube deviates due to deformation in the flaring process is prevented.
Description
technical field [0001] The invention relates to the technical field of automobile rear axle shafts, in particular to a flaring mold for automobile rear axle shaft tubes. Background technique [0002] The expansion of the axle tube of the rear axle of the automobile means that one end of the axle tube of the rear axle of the automobile is cylindrical, and the other end of the axle tube is extruded and flared by a cold stamping die to become a conical structure. connection, and meet the requirements of the bending moment at different axial positions of the shaft tube; most of the existing tapered shaft tubes are produced by casting or stamping with a special mold for design, and the upper and lower pieces are combined and welded to produce, often in the production process The position of the axle tube of the rear axle of the car is shifted due to deformation, resulting in uneven thickness of the flared part of the axle tube of the rear axle of the car.
