Steel pipe straightening device

Abstract

The invention provides a steel pipe straightening device. The steel pipe straightening device comprises a machine frame, a straightening plate, a straightening mold, a base and a handle. The straightening plate is hinged to the machine frame, a groove hole and adjusting holes are formed in the straightening plate, the groove hole is located in the center of the straightening plate, and the adjusting holes are symmetrically distributed in the two sides of the groove hole. The straightening mold comprises an upper mold wheel and a lower mold wheel, the upper mold wheel and the lower mold wheel are symmetrically arranged up and down, the upper mold wheel is connected with the straightening plate, and the lower mold wheel is rotationally connected with the base. The handle is located at one end far away from the machine frame and fixedly connected with the straightening plate. According to the steel pipe straightening device in the technical scheme, the mold is divided into an upper part and a lower part, and straightening is carried out in a pressure straightening manner; the size of the mold is adjustable, and the steel pipe straightening device is suitable for straightening different-specification steel pipes; and the lever principle is used, the structure is simple, operation is convenient, and the straightening effect is obvious.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a steel pipe straightening device. Background technique [0002] In the existing technology, during the production of steel pipes, due to insufficient cooling time and high straightening temperature, the expected effect cannot be achieved, which affects the straightening quality. After most steel pipes are straightened by a straightening machine, there will still be local bending phenomena, and the cost of straightening again will increase, time-consuming and laborious. In addition to the production process, due to transportation reasons, the steel pipe will also be bent, which will affect its use. The existing simple straightening device has a small application range, and often cannot adapt to steel pipes of various specifications. Contents of the invention [0003] In order to solve the above technical problems, the technical solution adopted by the present in...
