Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel tube plates, in particular to a bending machine for processing stainless steel tube plates. Background Art

[0002] Stainless steel tube sheet usually refers to a tubular product made from stainless steel sheet after processing, which is used to transport liquids, gases and other media. Stainless steel tube sheet has the characteristics of corrosion resistance, high temperature resistance, and high strength. The bending machine can bend the stainless steel sheet into the required shape according to the design requirements to adapt it to different engineering needs. The use of a bending machine can quickly and accurately complete the bending process of the pipeline, saving manpower and time costs and improving production efficiency. Local stress concentration will occur in the stainless steel tube sheet during the bending process. This is because in the bending area, the inner side of the tube sheet will be subjected to compression force, while the outer side will be subjected to tension force, which will lead to uneven distribution of local stress.

The existing bending machine for stainless steel tube sheet processing cannot process the surface of the stainless steel tube sheet when bending the stainless steel tube sheet, resulting in cracks or ruptures in the stainless steel tube sheet.
