Embodiment

[0035] Example: such as figure 1 Shown, be a kind of semi-shaft casing production technique disclosed by the present invention, mainly comprise the following steps:

[0036] S1: Heating, choose seamless steel pipe blanks, use seamless steel pipes as raw materials for processing, no need to punch the blanks, and the seamless steel pipe itself has a central hole, thereby reducing the generation of residual materials and improving the utilization rate of raw materials. The blank is heated by a first heating furnace, which is an induction heating furnace. Because the induction heating furnace uses the electromagnetic induction effect to heat the billet, it will produce a skin effect. Skin effect means that when there is alternating current or alternating electromagnetic field in the conductor, the current distribution inside the conductor is uneven, and the current is concentrated in the "skin" part of the conductor, that is to say, the current is concentrated in the thin layer o...

Abstract

The invention discloses an axle shaft sleeve production process, and belongs to the technical field of axle shaft sleeves. The process mainly comprises the following steps of S1, heating, wherein a first heating furnace is used for heating a blank, and the initial forging temperature is 1100 to 1150 DEG C; S2, forging, wherein the heated blank is placed in a mold to be subjected to forging and pressing to form a semi-finished product; S3, quenching, wherein a second heating furnace is used for heating the semi-finished product, the semi-finished product is heated to 840 DEG C, and the heated semi-finished product is immersed into a quenching pool to be cooled; S4, tempering, wherein the quenched semi-finished product is placed in a tempering furnace to be heated to 550 DEG C, and oil cooling is carried out; and S5, turning, wherein a lathe is used for roughly turning the two end faces and the outer circle side wall of the semi-finished product, the inner wall of the semi-finished product is roughly turned, the numerical control lathe is used for finish turning the workpiece after rough turning, and the blank in the S1 is a seamless steel pipe. The process has the advantage of improving the raw material use rate.

Description

technical field [0001] The invention relates to the technical field of half-shaft casings, more specifically, it relates to a production process of half-shaft casings. Background technique [0002] The half shaft sleeve is an important part of the automobile drive axle assembly. It is integrated with the drive axle housing to fix the axial relative position of the left and right drive wheels, and supports the frame and the mass of each assembly on it. When driving, it bears the road surface reaction force and moment transmitted from the wheels, and transmits it to the frame through the suspension. Because of its hollow tubular structure, in order to improve the utilization rate, the half-shaft casing is produced by forging process. [0003] At present, the document "Introduction to the Half-shaft Casing Process Scheme" (author chenwei0837) uploaded by Baidu Library on February 5, 2015 discloses a half-shaft casing process, S1, heating the blank; S2, upsetting and removing t...
