Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, specifically a pipe bending device for building construction. Background Technology
[0002] During building construction, the installation locations of pipelines need to be planned simultaneously. Pipelines often require bending during installation to meet the requirements of different scenarios; therefore, pipeline bending devices are needed to bend the pipelines.
[0003] Chinese patent application number 202410785813.X discloses a pipe bending device for building construction, comprising a workbench and a control cabinet, and further comprising: a guide rail, the guide rail being fixedly installed on the workbench; a movable seat, the movable seat being disposed on the guide rail and slidably connected to the guide rail; a drive assembly, the drive assembly being used to control the movable seat to move on the guide rail; a rotation assembly, the rotation assembly comprising a rotation shaft and a first motor, the rotation shaft being arranged laterally and rotatably connected to the movable seat, the first motor being electrically connected to the control cabinet and used to control the rotation shaft to rotate; a limiting assembly, the limiting assembly comprising a limiting tube and a fixing tube, the limiting tube being fixedly connected to the rotation shaft and keeping parallel to the rotation shaft, a first magnetic ring being fixedly installed on the front end face of the limiting tube, the inner diameter of the fixing tube being the same as the inner diameter of the limiting tube, the fixing tube being used to fix the pipe, and a second magnetic ring being fixedly installed on the rear end face of the fixing tube, the second magnetic ring being in contact with the first magnetic ring; the pipe is fixed by fixing the fixing tube to the inner wall of an annular groove. When the second motor starts, the bending ring moves the pipe, causing it to bend at the contact point with the inner wall of the annular groove. This device, on the one hand, prevents the pipe within the limiting tube from deforming due to external forces, thus improving the bending effect; on the other hand, because the limiting tube and the annular groove are tangent, and the distance between the limiting tube and the tangent point is very small, the contact between the bent part of the pipe and the inner wall of the annular groove is even tighter, further enhancing the bending effect.
[0004] The pipe bending device used in building construction can only bend pipes of a single size. If it is used to bend smaller pipes, it cannot make the pipe fit against the inner wall of the annular groove, which reduces its practicality. Therefore, we propose a pipe bending device for building construction. Utility Model Content
