Abstract

The invention discloses a large-diameter thin-wall steel pipe strengthening machine and an anti-deforming side roller device thereof. The anti-deforming side roller device comprises a connecting bracket, a roller assembly, a movable support plate and a hydraulic cylinder, wherein the connecting bracket comprises a lug which is used for fixing the connecting bracket on the large-diameter thin-wall steel pipe strengthening machine; the hydraulic cylinder is arranged on the connecting bracket; the roller assembly is arranged on the first side face of the movable support plate; and a piston rod of the hydraulic cylinder is connected to the second side face of the movable support plate to drive the roller assembly to move along the horizontal direction. The device has the advantages of capability of greatly improving the strengthening quality of the steel pipe, compact structure, low cost, high exchangeability, small occupied space, low fault rate and easiness for maintenance.

Description

technical field [0001] The invention relates to a device for preventing elliptical deformation during straightening of large-diameter thin-walled steel pipes, in particular to an anti-deformation side roller device for a large-diameter thin-walled steel pipe straightening machine, and also relates to a large-diameter thin-walled steel pipe comprising the device Steel pipe straightening machine. Background technique [0002] In the traditional vertical straightening machine, the straightening rollers are divided into upper and lower groups. When straightening large-diameter thin-walled steel pipes (generally, steel pipes with a diameter exceeding (That is, the aforementioned large-diameter thin-walled steel pipe, the same below) can be flattened to form an elliptical deformation under the pressure of the upper and lower straightening rollers. [0003] The current technology of large-diameter thin-walled steel pipe straightening machine such as figure 1 with figure 2 As sh...
