Problems solved by technology

But it has the following problems: it needs to change the pipe bending die to adapt to the application requirements of different bending requirements (different bending radii and bending arc lengths), and the application is relatively inconvenient; and it cannot be better adapted to seamless pipes of different pipe diameters. Steel Pipe

Abstract

The invention discloses a general seamless steel pipe bending machine, and belongs to the technical field of pipe bending machines. The general seamless steel pipe bending machine comprises a rack, abending mechanism, a first clamping mechanism and a second clamping mechanism, wherein the first clamping mechanism and the second clamping mechanism are clamped on the two end sides of seamless steelpipes correspondingly; the first clamping mechanism comprises an upper clamping block and a lower clamping block; the second clamping mechanism comprises an upper clamping plate and a lower clampingplate; the bottom of the lower clamping plate is connected with a hydraulic cylinder, the lower clamping block is connected with a longitudinal sliding block sleeving a longitudinal lead screw, jacking plates are fixedly connected to the longitudinal sliding block and the lower clamping plate correspondingly, compressing screws are arranged on the jacking plates in threaded fit and penetrating modes, and a pair of rolling wheels is arranged between the upper clamping plate and the lower clamping plate; and the bending mechanism comprises a circular rotating disc with a sliding rail formed in the front face, two adjusting sliding blocks are arranged on the sliding rail, and the upper clamping plate and the lower clamping plate are fixed to the two adjusting sliding blocks correspondingly. The radian consistency of bent parts of the seamless steel pipes can be guaranteed, the bending radius can further be adjusted, the bending arc length can further be controlled, thus the general seamless steel pipe bending machine can be general for the seamless steel pipes of different pipe diameters, and application is convenient.

Description

technical field [0001] The invention relates to the technical field of pipe benders, in particular to a universal seamless steel pipe bender. Background technique [0002] Seamless steel pipes have a hollow cross-section and are widely used as pipes for conveying fluids, such as pipes for conveying oil, natural gas, gas, water and certain solid materials. Pipe bending, in the prior art, the pipe bending work is generally performed manually by workers, and repeated operations are required to process a pipe bend, which wastes a lot of manpower and increases the workload of pipe benders. Due to the manual operation of workers, there are still some potential safety hazards, the bending accuracy of the bent pipe is relatively poor, and the labor productivity is low. Some thin-walled steel pipes are prone to collapse and internal wrinkles when the pipe is bent, resulting in damage to the appearance of the steel pipe, and may also make it impossible to install and use. The existing...
