Correction device for steel pipe formed by coiling steel strip

Abstract

The invention provides a correction device for a steel pipe formed by coiling a steel strip. The correction device comprises a working table, and a correction hole is formed in the middle of the working table; the front and rear sides of the correction hole are symmetrically provided with mounting plates, and longitudinal correction wheels are arranged at the upper and lower ends of the mounting plates symmetrically; the longitudinal correction wheels are located in the correction hole and in the position above the correction hole separately, and the right and left sides of the correction holeare each provided with two transverse correction wheels; the transverse correction wheels are arranged at the front and rear parts of the working table symmetrically, and all the transverse correction wheels and the outer sides of the mounting plates are provided with position regulating rods; and the position regulating rods are provided with regulating valves. Through arrangement of the transverse correction wheels and the longitudinal correction wheels, the correction is performed from the upper and lower sides and the right and left sides of a steel pipe through rotation of the correctionwheels, and the extrusion force is reduced; and the correction effect is improved, and the correction device is simple in structure and convenient in use.

Description

technical field [0001] The invention relates to the field of steel pipe production, in particular to a correction device for coiling a steel strip into a steel pipe. Background technique [0002] The steel strip is rolled into a steel pipe, and the steel strip is rolled and compressed, and the joint seam is welded by a welding device to form a steel pipe. During the welding, blanking, and handling of the steel pipe, the steel pipe will be bent and deformed due to collisions and other reasons, and a correction device is required to correct the steel pipe. For correction, the existing steel pipe correction devices use briquetting blocks to correct the extrusion of steel pipes, but the strength of steel pipes rolled into steel pipes is relatively small compared with ordinary steel pipes, and it is easy to produce depressions during the extrusion correction process. Therefore, to solve this problem, it is necessary to become very important. Contents of the invention [0003] ...
