Embodiment Construction

[0023] like figure 1 As shown, driving wheels 4, 5, a first driven wheel 6, and a second driven wheel 7 are arranged on the circle calibration body 1. The driving wheel can move left and right relative to the driven wheel, and the driving wheel and the driven wheel cooperate to clamp the elbow port to carry out Elbow port calibration; the first driven wheel 6 is used to correct the concave position in the elbow port, and the outer side of the first driven wheel 6 is provided with an arc-shaped shell, and the second driven wheel 7 is used to correct the convex position in the elbow port. Starting position; two driven wheels are respectively positioned at both sides of the driving wheel, and the axles of the first driven wheel 6, the second driven wheel 7, and the driving wheel are arranged parallel to each other. The line connecting the positions of the two driving wheels 4 and 5 is perpendicular to the line connecting the positions of the two driven wheels.

Abstract

The invention relates to a device for correcting the ovality of a port of a large elbow pipe fitting. The device comprises an ovality correcting body used for installing an ovality correcting part andis characterized in that a driving wheel and a driven wheel are arranged on the ovality correcting body, the driving wheel can move left and right relative to the driven wheel, the driving wheel andthe driven wheel can be coordinated with each other to clamp a port of an elbow so as to correct the ovality of the port, and a first driving motor for driving the driving wheel to rotate and a driving wheel translation driving mechanism for driving the driving wheel to move left and right are correspondingly arranged on the ovality correcting body.

Description

technical field [0001] The invention relates to a device for correcting the ellipticity of the port of a large elbow pipe fitting. Background technique [0002] At present, the manufacturing process of large-scale elbow pipe fittings is to form two semicircular arc-shaped sheet parts by mold pressing, and then weld the two semicircular arc-shaped sheet parts to synthesize the elbow pipe fittings. In the process of forming and welding, a certain amount of ellipticity will be generated at the elbow port, and the ellipticity of the elbow port needs to be corrected (circle calibration) to meet the standard requirements. The existing roundness correction method is to heat and burn the part of the elbow port with a flame gun, manually smash it with a sledgehammer, and repeat the heating several times to adjust the roundness. , Low production efficiency. Contents of the invention [0003] The object of the present invention is to provide a device for correcting the ellipticity ...
