Description

Technical Field

[0001] The utility model relates to the technical field of railing bending, in particular to a bending device for processing metal railings. Background Art

[0002] Metal railings are a type of guardrail, fence or barrier made of metal material. Its main function is to isolate and protect specific areas or people. Metal railings have the advantages of high strength, durability, aesthetics and safety.

[0003] In actual needs, curved metal railings are needed to increase the aesthetics, so a bending machine is needed to shape and bend the metal railings during the metal railing processing.

[0004] The existing patent (publication number: CN219211200U) discloses a bending machine for processing metal railings, including a workbench, the top of which is fixedly connected with a hydraulic telescopic rod, a limit frame and a bender, and the interior of the bender is respectively provided with a clamping member and a fixing member. The improved bending machine, through the cooperation between the clamping member, the fixing member and the bender and other structures, uses the clamping member and the fixing member to limit and fix one end of the metal railing during the process of bending the metal railing using the bender, to ensure that the metal railing will not shake inside the bender during the process of bending the metal railing by the bender, thereby avoiding bending deviation. By opening an arc groove on the surface of the bender, the bending shape of the metal railing is limited during the bending process by the bender, so that the bending curvature of the metal railing will not change, thereby ensuring the processing quality of the metal railing product.

[0005] In the above solution, it is impossible to adjust the railings of different specifications, and the bending effect will be affected by the different thicknesses of the railings during use. Utility Model Content
