Abstract

The invention discloses a rectangular pipe straightener comprising a frame, a motor and a reducer. The motor and the reducer are fixed under the frame. Two parallel wall plates are arranged above the frame. A rectangular pipe straightening mechanism set is arranged between the wall plates and comprises carrier rollers and a plurality of compression rollers. The carrier rollers are arranged at the bottoms of the wall plates. The compression rollers are arranged on the lower portions of the tops of the wall plates. Clearances between the upper faces of the carrier rollers and the lower faces of the compression rollers form straightening passages to allow the rectangular pipes to pass. The motor drives the reducer to drive the carrier rollers to rotate, and meanwhile, a transmission mechanism is arranged between two carrier rollers and two compression rollers which are arranged at two ends of the rectangular pipe straightener mechanism. Each transmission mechanism drives the two compression rollers to rotate. The compression rollers are connected with the wall plates through bearing seats. Adjusting mechanisms are arranged between the wall plates and the bearing seats to drive the bearing seats to move vertically. The rectangular pipe straightener is convenient to operate and adjust, capable of straightening the rectangular pipes with different sizes and high in straightening accuracy.

Description

technical field [0001] The invention relates to steel pipe manufacturing equipment, in particular to a rectangular steel pipe straightening machine. Background technique [0002] For roller tubes with high precision requirements and special tubes for mechanical equipment, there are not only strict requirements on steel grade and weld quality, but also high requirements on the straightness of steel pipes, because the deviation of straightness is directly related to the oil sleeve. Processing and connection of pipe end threads and pipe collars of pipes and conveying pipes. There are two processing forms of existing pipe end turning: rotating the pipe (turning) or rotating the tool (tapping or threading). The degree is higher. [0003] The adjustment of the straightening reduction is realized by adjusting the distance between the upper and lower rollers according to the material, curvature and required precision of the steel pipe to be straightened. Generally, the regulation...
