Processing method of mould of cambered special-shaped brick

Abstract

The invention discloses a processing method of a mould of a cambered special-shaped brick, comprising the following steps of: processing a blank of a corresponding steel mould according to a camber figure regularity of a planform of the cambered special-shaped brick; cutting an inner hole of the blank by using a radial regulating and controlling method; finally forming four modules relevant to a needed camber with the radial of the inner hole gradually prolonged to a half of the diagonal length of the section of the blank, and then opening along a center line so as to obtain the steel mould of the mould of the cambered special-shaped brick. The invention is more convenient and accurate and low in repair when assembled with a matched general detachable edge and a matched detachable blocking lining, thereby greatly enhancing the production efficiency and shortening the production period.

Description

technical field [0001] The invention relates to a processing method of a special-shaped brick mold, in particular to a processing method of a special-shaped brick mold with a partial curved surface. Background technique [0002] In recent years, the state has advocated energy saving, consumption reduction, and environmental protection, and some small and medium-sized coke ovens have been forced to shut down. Therefore, large-scale environmental protection coke ovens are very marketable, but there are many types of coke oven bricks to match them, and they are used in coke oven fuel chambers. The special-shaped surface hollow brick W11 (such as figure 1 shown) accounted for the majority. [0003] Normally, the cold processing procedure adopted for processing the corresponding steel mold blocks here is: first refer to the boundary curve as a reference line, because in terms of brick shape alone, the boundary curve of each surface is formed by the coke oven brick The countless...

Problems solved by technology

[0003] Normally, the cold processing procedure adopted for processing the corresponding steel mold blocks here is: first refer to the boundary curve as a reference line, because in terms of brick shape alone, the boundary curve of each surface is formed by the coke oven brick The countless trajectory points provided by the designer are displayed in the large sample formed by connection; then the planer operator refers to the scribing standard and manually processes the shape. The disadvantage of the steel module processed in this way is that the steel mold is divided into pieces. The shape is greatly different due to the influence of human factors, and it is easy to deform

When 4 modules are assembled, it brings great inconvenience to the assembly of the mold, and frequent repairs are required, and the accuracy of the modules and the accuracy of the shape cannot be guaranteed.

For this reason, we had to give up machine pressing and change to manual molding. However, the demand for this special-shaped curved hollow brick W11 brick is large, and manual molding cannot meet the requirements of the contract period, resulting in the quality of the bricks not meeting the standard and even delaying the contract.
