Tube bending machine for seamless steel tubes

Abstract

The invention discloses a tube bending machine for seamless steel tubes, and belongs to the technical field of tube bending machines. The tube bending machine comprises a base provided with a mountinggroove; a first screw and sliding block structure arranged transversely and a round rotating disk located above the first screw and sliding block structure are arranged in the mounting groove; a sliding rail extending along the radius of the round rotating disk is arranged on the front side of the round rotating disk; an adjusting sliding block is arranged on the sliding rail; one U-shaped clamping sleeve is fixed to the adjusting sliding block; a vertically-fixed hydraulic cylinder is arranged on one side of the U-shaped clamping sleeve; the other U-shaped clamping sleeve parallel with the U-shaped clamping sleeve is fixed to the top of the hydraulic cylinder; a pair of rolling wheels are arranged on the inner side of each of the two U-shaped clamping sleeves; a driving shaft of a gear is fixedly sleeved with the back end surface of the round rotating disk; the upper end of a transverse sliding block is connected with a second screw and sliding block structure arranged longitudinally; and a rack plate meshing with the gear is connected onto the second screw and sliding block structure. With the adoption of the tube bending machine, collapsing or internal wrinkling of the inner arc sides of the seamless steel tubes can be prevented, the radian consistency of the bent part of the seamless steel tubes can be guaranteed, the bending radius can be adjusted, the bending arc lengthcan be controlled, and the tube bending machine is relatively convenient to use.

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 section and are used in large quantities as pipelines for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Seamless steel pipes may need to be processed into a certain degree of curvature in the actual application process. Bending pipes. In the prior art, the pipe bending work is generally performed manually by workers. The processing of a bend requires repeated operations, which wastes a lot of manpower and increases the workload of the pipe bending personnel. Due to the manual operation by the workers, there is still some The safety hazards of the elbow, the bending accuracy of the elbow is relatively poor, and the labor productivity is low. Some thin-walled steel pipes are prone to collapse and interna...
