Embodiment Construction

[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0013] The specific method is:

[0014] The specific method is:

[0015] 1. After the liner is damaged, it is not necessary to remove the original old liner, but to cover the damaged part with a layer of high-carbon cast steel liner.

[0016] 2. When the liner is installed, the size requirements for the connection between the center hole and the spigot are very strict. High-chromium cast iron cannot be cut or polished. If the center hole is slightly deviated, the spigot cannot be connected. Although the hardness of high-carbon cast steel is above HRC60 , but it can be cut with plasma flame. Therefore, we do not cast slits to reduce the accuracy requirements for butt joints. Instead, we adopt the method of covering the joints around, see the spe...

Abstract

The invention relates to a covering and repairing method for a broken lining plate of a shot blasting machine. The method specifically comprises the steps that firstly, after the lining plate is broken, an original old lining plate does not need to be dismounted, and the damaged portion is covered with a high carbon cast steel lining plate; secondly, when the lining plate is mounted, the requirement for the connecting size of a central hole and an auxiliary opening is very strict, high-chromium iron cannot be cut and polished, and if the central hole slightly deviates, the auxiliary opening cannot be in abut joint with the central hole; and although the hardness of the high carbon cast steel is more than HRC 60, the high carbon cast steel can be cut through plasma flames, so that the measure that the auxiliary opening is not cast is taken so as to reduce the precision requirement during butt joint, the method of peripheral covering lap joint is adopted, and the specific construction method is achieved. According to the replacement method, the damaged portion is dismounted, the peripheral lining plate is loosened, the peripheral auxiliary opening is strictly aligned through a new plate and is aligned with the central hole, and all bolts are fastened; and according to a covering method, the damaged portion is not dismounted, the peripheral lining plate does not need to be loosened, the lining plate for covering the peripheral auxiliary opening is used for cutting out a central hole A, and a bolt of the central hole A is fastened.

Description

technical field [0001] The invention relates to the field of shot blasting machines, in particular to a supplementary repair method for broken lining plates of shot blasting machines. Background technique [0002] After the liner of the shot blasting machine is broken, it is very troublesome to repair. The old liner is removed, and after surveying and mapping, model making, casting and other processes, it greatly affects production. This is called substitution. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a repairing method for the broken liner of the shot blasting machine. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] The specific method is: [0006] 1. After the liner is damaged, it is not necessary to remove the original old liner, but to cover the damaged part with a layer of high-carbon cast steel liner. [000...
