Problems solved by technology

[0004] However, because the contact area of ​​the multi-head ejector 02 is small, it belongs to point contact, and the support circle of this technology has the disadvantage of uneven circle adjustment.
The circle adjustment device relies on the wrench to support one by one manually, which is inefficient and labor-intensive
At the same time, since the circle is supported from the inner wall of cylinder 01, and the outside of cylinder 01 is free to deform, the support circle mainly undergoes elastic deformation. Once the device is withdrawn, it will inevitably rebound, and the circle correction effect cannot be maintained, and the circle correction effect of the circle correction device is poor.

Abstract

The invention discloses a plastic circle correction device, which comprises an outer restraint die assembly of a cylinder and an inner expansion correction circle correction assembly for correcting the inner side of the cylinder. round face. When it is necessary to carry out the circle correction operation on the cylinder body, by setting the restraint mold assembly outside the cylinder body on the outside of the cylinder body, and the inner stretching circle correction component is arranged on the inside of the cylinder body, and through the inner stretch circle correction component to expand the circle outwardly, The outer wall of the cylinder and the calibration surface of the outer wall are fitted and corrected. By setting the cylinder outer restraint mold assembly on the outer wall of the cylinder, when the inner stretching circle calibration component performs circle calibration work, the cylinder outer wall is constrained by the limit piece of the cylinder outer restraint mold assembly to deform, thereby avoiding the cylinder circle calibration The situation that the effect cannot be maintained, therefore, the circle correction effect of the plastic circle correction device provided by the present application is improved.

Description

technical field [0001] The invention relates to the technical field of cylinder circle calibration, in particular to a plastic circle calibration device. Background technique [0002] In the field of high-voltage electrical switchgear, it is especially suitable for, but not limited to, using the shape-correcting device in the manufacturing process of the shell of gas-insulated metal-enclosed combined electrical equipment (GIS for short). It is especially suitable for but not limited to a shape correction technology and device used in the manufacturing process of gas-insulated metal-enclosed rigid transmission line (abbreviated as GIL) shell. GIS (including HGIS) and GIL products are electrical equipment packaged in airtight enclosures, which can be collectively referred to as high-voltage electrical equipment. Because the shell of high-voltage electrical equipment is mainly welded by cylinders, flanges, and branch pipes. The main body of the casing is a cylinder, or the su...
