Description

Rectangular pipe cold bending forming device Technical Field The utility model belongs to the technical field of rectangular tube processing, and particularly relates to a rectangular tube cold-bending forming device. Background The rectangular pipe is also called as a rectangular steel pipe or a rectangular section steel pipe, is a steel pipe with a rectangular cross section, and the rectangular pipe is often required to be bent when being processed by the conventional rectangular pipe, and a corresponding cold bending forming device is required to be used when the rectangular pipe is bent; The existing cold roll forming device is characterized in that when the existing cold roll forming device is in actual use, a rectangular pipe is placed in a limiting groove formed in one side of a limiting block, the rectangular pipe is attached to a bending rotating shaft, then the rotating shaft rotates to drive the limiting block to rotate along with the bending rotating shaft, so that the rectangular pipe is driven to be formed in a cold roll mode, but after bending treatment is finished, the rectangular pipe is deformed, so that the rectangular pipe is easy to clamp in the limiting groove of the limiting block, when the rectangular pipe is removed, workers are required to pry down the clamped rectangular pipe by means of tools, the operation is troublesome, and the rectangular pipe is inconvenient to release after the limiting block is limited and bent on the rectangular pipe.
