Inner supporting type elbow pipe orifice roundness correcting machine

Abstract

The invention relates to an inner supporting type bend pipe orifice roundness correcting machine which comprises a fixed rack. The three-way moving mechanism is mounted on the fixed rack; the pipe supporting device is mounted in the three-way moving mechanism; the pipe supporting device comprises a pipe supporting device frame body, a circumferential rotating mechanism, a push rod sliding block mechanism and a laser ranging mechanism, the circumferential rotating mechanism drives the push rod sliding block mechanism to rotate, and the push rod sliding block mechanism comprises a push rod fixing frame, a pipe supporting hydraulic oil cylinder, a middle push rod, a middle connecting rod and a movable sliding block. The two movable sliding blocks are symmetrically assembled in movable sliding block guide rails arranged on the push rod fixing frame, the pipe supporting hydraulic oil cylinder is connected with the oil cylinder push rod, the oil cylinder push rod is rotationally connected with the middle push rod through the cover plate, the middle push rod is hinged to the movable sliding blocks through the middle connecting rod, and the front end of each movable sliding block is provided with a pipe supporting block. The laser ranging mechanism comprises a stepping motor and a laser range finder. The pipe straightening machine can automatically realize pipe fitting centering, elbow pipe orifice short diameter alignment and hydraulic pipe bracing, and is reliable in work, high in rounding precision and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of industrial machinery, and in particular relates to an inner support type bend pipe mouth rounding machine. Background technique [0002] Elbows are important components widely used in various fields of industry, and are indispensable in pipeline transportation. Equal wall thickness elbows have important uses in the fields of petroleum, chemical industry, navigation, aviation and nuclear industry, and have special significance in high temperature, high pressure and acid-base corrosion environments. When the elbow is bent, the mouth of the elbow is easily deformed and becomes elliptical. In order to ensure the seamless connection between the elbow and the straight pipe, the mouth of the elbow must be rounded. At present, there is no relatively mature tool for rounding the nozzle of the elbow on the market. The common method used by workers is: manually use a ruler to measure the short diameter of the nozzl...

AI Technical Summary

Problems solved by technology

At present, there is no relatively mature tool for rounding the nozzle of the elbow on the market. The common method used by workers is: manually use a ruler to measure the short diameter of the nozzle of the elbow, and multiple people cooperate with hydraulic cylinders or jacks to support the rounding of the pipe.

This method is time-consuming and labor-intensive, the accuracy of supporting the tube is low, and the efficiency of supporting the tube is low, which cannot meet the production demand
