Method for repairing molding surface of blade rolling mold

Abstract

The invention relates to a method for repairing a molding surface of a blade rolling mold. The method comprises the following steps of: checking the allowance of the molding surface of the blade rolling mold, drawing grid lines, rolling a blade of which the molding surface can meet the repairing requirement, repairing the side parts of the rolling mold; measuring the blade molding surface and finding the molding surface position of the rolling mold corresponding to a blade out-of-tolerance part, setting the repairing amount of the rolling mold and sequencing the parts of the rolling mold, processing problems generated during the repairing process, and ensuring the surface quality of the rolling mold; and checking the allowance of the molding surface of a new rolling mold, drawing grid lines on the molding surface of the new rolling mold, rolling the blade, measuring the molding surface of the blade, finding out the part of the blade, exceeding an acceptance tolerance, and determining the repaired part through grids on the rolling blade and corresponding the determined parts to the rolling mold. The method has the advantages that about one third of the repairing period is shortened; about 30 mold repairing test pieces in every set of molds are reduced; particularly, the repairing of the rolling mold for rolling the complicated blades with curved surfaces can be realized by using the method; and the product quality of the blades is greatly improved.

Description

technical field [0001] The invention relates to the field of surface repair of blade rolling dies, in particular to a method for repairing the profile of blade rolling dies. Background technique [0002] The surface repair of the blade rolling die mainly relies on skilled personnel to carry out the surface repair of the rolling die with their own experience. Because some skilled personnel do not master the requirements and methods of mold repair, the repair cycle of the rolling die is prolonged and consumes a lot of model test piece. In more serious cases, the rolling dies will be scrapped, seriously affecting the production schedule and causing unnecessary economic losses. Contents of the invention [0003] The purpose of the present invention is to realize accurate and simple surface repair of rolling dies, especially to solve the difficult problem of repairing the rolling profiles of blades with complex profiles, and to accurately correspond to the correspondence betwe...
