Seamless steel pipe bending machine

Abstract

The invention relates to the technical field of tube bending machines, in particular to a seamless steel tube bending machine. The seamless steel tube bending machine comprises a rack and two side wings arranged on the rack. A rotating block is rotationally connected between the side wings and detachably connected with a semicircular tube bending die. A tube bending groove matched with a seamless steel tube is formed in the circumferential face of the tube bending die. A drive mechanism is arranged on the rack. A supporting plate is arranged below the rotating block and provided with a supporting groove matched with the seamless steel tube. A clamping mechanism for clamping the seamless steel tube to the tube bending die is arranged on the rotating block. A sliding frame is arranged at the side of the side wings and is in sliding connection with a sliding block. A plug is arranged at one end of the seamless steel tube, and the other end of the seamless steel tube is communicated with a high-pressure air source. The seamless steel tube bending machine is simple in structure and convenient to use, the tube bending die is conveniently replaced, and the tube bending efficiency is high; and high-pressure air is introduced into the seamless steel tube, and therefore some steel tubes with the small wall thickness can be prevented from collapsing or wrinkling inside during tube bending, and the tube bending precision is high.

Description

technical field [0001] The invention relates to the technical field of pipe bending machines, in particular to a seamless steel pipe bending machine. 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 ...
