Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] This embodiment relates to a corrosion-resistant shaft, such as figure 1 As shown, it consists of a shaft core 11 and a corrosion-resistant skin 12 wrapped on the shaft core 11 . Wherein, the shaft core 11 is processed into a columnar body from cast iron. The corrosion-resistant skin layer 12 is made of corrosion-resistant metal or alloy material, such as stainless steel, titanium alloy and the like. The specific material used for the corrosion-resistant skin layer 12 depends on the application scenario of the corrosion-resistant shaft. The thickness of the corrosion-resistant skin layer 12 is very thin, no more than 0.5 mm, generally 0.1-0.2 mm. The corrosion-resistant skin layer 12 is welded on the cylindrical surface of the shaft core 11 by means of laser spot welding, so that the shaft body processed by ordinary cast iron also has properties suc...

Abstract

The invention discloses a machining method of a corrosion-resisting shaft and the corrosion-resisting shaft. The method comprises the six technology steps of leather preparing, dense trepanning, trepanning spot welding, gap spot welding, end face spot welding and welding spot polishing. Specifically, wrapping leather similar to a columnar face of an axis part in size dimension is cut from corrosion-resisting leather firstly, densely-distributed welding holes are formed in the wrapping leather obtained by cutting, then, the wrapping leather is tightly attached to the columnar face of the axis part in a wrapping manner, the welding holes are subject to laser spot welding, welding point polishing is carried out through gap spot welding and end face spot welding, the welding spots on the surface of a shaft body are smooth, the corrosion-resisting leather can be firmly attached to the axis part, and the shaft body machined through common cast iron processing also has the properties of corrosion resistance, wear resistance and the like. Compared with the shaft body wholly made of the alloy high in corrosion and wear, the structure greatly reduces the material cost.

Description

technical field [0001] The invention relates to a corrosion-resistant shaft processing technology. Background technique [0002] Shafts are used in various mechanical equipment. Ordinary shafts are usually manufactured from cast iron. For mechanical equipment used in the chemical industry, the shaft body made of cast iron is easily corroded by chemical substances. For this reason, under the prior art, the entire shaft bodies of these mechanical devices are made of corrosion-resistant materials. In some special chemical fields, the required corrosion-resistant materials are special and expensive, and only the shaft needs to consume high material costs. Contents of the invention [0003] The problem to be solved by the present invention is to reduce the cost of shafts of mechanical equipment in some special chemical fields. [0004] In order to solve the above problems, the scheme adopted by the present invention is as follows: [0005] According to a method for process...
