Axial flow fan cylinder body opening deformation processing method

Abstract

The invention belongs to a machinery industry and provides an axial flow fan cylinder body opening deformation processing method which is simple, convenient, practical and capable of solving the problem of cylinder body joint face opening deformation of an axial flow fan or other horizontal relates to split type flanges, especially for solving the opening deformation problem of an air inlet side air seal cavity portion of an axial flow fan cylinder body produced by Shanghai automotive industry corporation. The axial flow fan cylinder body opening deformation processing method is characterized in that a flange joint face portion of any cylinder body is additionally machined with a key groove according to a sealing shape, wherein the width of the key groove is 10% as that of the flange face, and the shape is a flange joint face sealing shape. The depth is arranged two times as that of deformation amount of the flange joint face opening, and the shape is an opening shape. The length is the length needing to be sealed, and the shape is the flange joint face sealing shape. A plurality of opening-shaped red copper strips are manufactured according to the sealing shape (the heights of the copper strips are properly smaller than the two-time deformation amount), the copper strips are in a natural fitting seal state with the other flange face, and therefore the copper strips can not be damaged by pressing after the cylinder body flange joint faces are jointed.

Description

Technical field [0001] The invention belongs to the machinery industry, and relates to a simple, quick and practical method for solving the deformation problem of the joint surface opening of an axial flow fan or other horizontally split flange cylinder bodies. In particular, it can solve the problem of partial opening deformation of the air seal chamber on the intake side of the axial flow fan cylinder produced by SAIC. Background technique [0002] At present, after the deformation of the joint surface of the axial flow fan or other horizontally divided flange cylinders, it needs to be returned to a professional manufacturing and repairing factory for heat treatment or laser repair, and finally grinding. However, after the cylinder body is installed and used for the first time, it will be deformed to varying degrees, and it will be difficult to reset according to the technical requirements if it is disassembled and installed again after many years of use. Generally, cylin...
