Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber rolling, in particular to a CDC shock absorber rolling machine. Background Art

[0002] After the CDC shock absorber is assembled, the top of the oil reservoir is in a straight cylindrical shape, and the internal oil seal and guide are not well fixed. Therefore, it is necessary to perform a rolling process on the top of the oil reservoir to roll and bend the straight cylindrical top so that it is directly pressed on the upper surface of the oil seal, thereby better fixing the oil seal and guide and improving the sealing level of the CDC shock absorber.

[0003] The CDC shock absorber has a special-shaped shape and cannot be fixed well to complete the rolling process.

[0004] The traditional straight tube rolling process has some defects in the rolling process: during the rolling process, due to the uneven performance of the material itself or improper setting of the rolling parameters, the material may deform unevenly, resulting in local excessive deformation or insufficient deformation, affecting the dimensional accuracy and shape of the product.

[0005] During the rolling process, if the lubrication between the roller and the material is poor, it may cause scratches, abrasions or other damage to the surface of the material, affecting the appearance and quality of the product.

[0006] During the rolling process, the material is subjected to large tensile and compressive stresses. If the plasticity of the material itself is insufficient or the rolling parameters are not properly controlled, cracks may appear in the material, affecting the strength and durability of the product.
