Description

Technical Field

[0001] The invention relates to the technical field of non-cutting processing of metal pipes, and in particular to a deformation correction device for axle half-axle sleeves. Background Art

[0002] The automobile drive axle is a device on the car that is used to transmit the driving force from the engine to the drive wheels, achieving the effect of reducing speed and increasing torque, while changing the direction of power transmission.

[0003] The half-axle 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 together support the frame and the mass of the assemblies thereon. At the same time, it withstands the road reaction force and torque transmitted from the wheels when the car is running, and transmits them to the frame through the suspension.

[0004] Existing half-axle sleeves are mainly of two types: integral type and split type. The difference between the two types is whether the half-axle sleeve body and the flange are integrally formed.

[0005] After the split half-axle sleeve is formed, it is directly pressed into the bridge housing from both ends.

[0006] Axle sleeves are mostly made of hot-rolled seamless steel pipes of carbon structural steel and alloy steel. The forming process mainly includes material selection, extrusion, welding, precision turning, etc. Since the axle sleeves are hollow pipes with a certain length in appearance and the wall thickness of the pipes is relatively thin, they are prone to bending and torsional deformation during the machining process, resulting in large deviations in the formed axle sleeves, affecting the quality of the finished product. Therefore, in the processing of axle sleeves, a correction process is usually added after extrusion and before welding to compensate for the bending deformation of the parts.

[0007] However, the existing equipment and processing methods have the following problems when used for bending correction of half-axle sleeves due to their single functions and poor specificity: 1. The correction method is single and has poor adaptability to different deformations. Specifically, the half-axle sleeve will undergo various deformations such as bending and twisting during the processing, but the existing equipment is limited by a single correction method and can only correct and compensate for specific deformations, resulting in poor processing adaptability and affecting the correction effect.

[0008] 2. Inconvenient adjustment of the correction part. Specifically, the deformation parts of the half-axle sleeves are random during the processing, which requires the half-axle sleeves to be clamped differently according to the different deformation parts during the correction process, and even requires the half-axle sleeves to be adjusted and transferred in real time during the correction process. The existing equipment is inconvenient to clamp in the process of half-axle sleeve bending correction. On the other hand, the half-axle sleeves cannot be adaptively moved and adjusted after clamping, which greatly reduces the correction efficiency.

[0009] 3. It is difficult to achieve local correction of deformation. Specifically, some local deformations on the half-axle sleeve cannot be corrected by overall torsion bending.

[0010] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Summary of the invention
