Description

Technical Field

[0001] The present invention belongs to the technical field of processing supports for thin-walled cylinders, and particularly relates to a support ring and a support device for cylinder processing. Background Art

[0002] In the manufacturing industry, large-diameter cylinders are increasingly widely used. However, various defects may occur during the processing, manufacturing, welding, and assembly of cylinders, which may affect the quality and performance of the containers. This is because the cylinders themselves have relatively low stiffness and are prone to deformation under the action of external forces. Therefore, strictly controlling the roundness of the cylinders during the processing, manufacturing, welding, and assembly of cylinders plays an important role in improving the processing quality of the cylinders. At present, during the processing, forming, welding, and assembly processes, the method for ensuring the roundness of the cylinders is basically to use manual support tooling and other methods for rough adjustment. The manual support tooling generally has an arc-shaped top structure. The arc-shaped tops of multiple support blocks form a circle. The lower part of the support rod is connected to a threaded rod, and the support blocks are driven by manually turning the bolts to tightly press against the inner wall of the cylinder. Although these methods have the characteristics of high flexibility and strong adaptability, they have many disadvantages: high labor intensity for workers; low precision, and the quality of cylinder support varies depending on the ability of the operating workers; low adjustment efficiency of the support tooling and waste of manpower; poor alignment effect between the axis of the support tooling and the axis of the cylinder, and there are problems such as non-concentricity of the two end faces of the cylinder and uneven stress on the contact surface between the cylinder and the support tooling, which are likely to cause deformation of the cylinder during the support process; the same support tooling cannot meet cylinders of multiple diameters.

[0003] Therefore, in the cylinder manufacturing industry, automation during the processing, manufacturing, welding, and assembly processes is very important. Researching and manufacturing a set of support devices for cylinder processing with high efficiency and high quality is necessary for cylinder manufacturing in terms of economy and practicality.
