Abstract
The invention discloses a combined rail train wheel manufacturing process, characterized by comprising the following steps: wheel hub manufacturing, wheel rim manufacturing, paint spraying and the like. The manufacturing process has the advantages of effectively protecting wheels, improving the service life of wheels and saving economic cost.
Description
Technical field
The present invention relates to field of track traffic, specifically a kind of combined orbit train wheel manufacturing process.
Background technology
It is bigger that the speed of existing high-speed train promotes degree, track traffic is after long-time operation, track travel face guides traveling through light rail train can cause noticeable wear vestige, at existing most of track train wheels, it uses the rolling of manganese alloy steel entirety, this kind of wheel is after tread produces a large amount of abrasion, entirety must be replaced scrapping, and its service life is not long and wastes material in a large number.And its reliability of common assembled vehicle wheel is low, it is impossible to meet growing growth requirement.
Summary of the invention
It is desirable to provide a kind of combined orbit train wheel manufacturing process, to solve the problems referred to above.
For achieving the above object, technical scheme is as follows:
A kind of combined orbit train wheel manufacturing process, it is characterised in that comprise the following steps:
A. choose cast iron or cast steel is raw material, intercept and process the crude green body of wheel hub, and crude green body is placed in annealing furnace makes annealing treatment, annealing furnace keeps temperature 800 ~ 940 DEG C, 15 minutes persistent period, then wheel hub is proceeded to spraying coating line dusts, to wheel hub successively cured after having dusted from processing line, the most quickly cool down, and its surface is carried out grinding process；
B. choosing manganese alloy steel is raw material, utilizes clasp to be fixed on wheel hub by rim after processing rim, and heating；
C. after b step completes, to rim surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；
D. at prime paint surface spraying/roller coating floating coat paint after step c completes, described floating coat paint is aliphatic polyurethane glass flake paint, paints three times polyurethane coating varnishes of spraying at floating coat continuously after being dried 0.5-1.5 hour.
Further, the coating layer thickness of described prime paint is 100 μm-120 μm.
Further, the coating layer thickness of described floating coat paint is 130 μm-150 μm.
Further, the coating layer thickness of described polyurethane coating varnish is 130 μm-150 μm.
The beneficial effects of the present invention is: the coating system that the present invention uses is compared, the paint film of one layer of application can be formed at wheel surface, in long-term walking process, before this paint film was rubbed, and can effectively extend the service life of wheel, and saved Financial cost.Secondly, the present invention uses assembled vehicle wheel, saves Financial cost.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described.
A kind of combined orbit train wheel manufacturing process, comprise the following steps: a. chooses cast iron or cast steel is raw material, intercept and process the crude green body of wheel hub, and crude green body is placed in annealing furnace makes annealing treatment, annealing furnace keeps temperature 800 ~ 940 DEG C, 15 minutes persistent period, again from process line, wheel hub is proceeded to spraying coating line dust, to wheel hub successively cured after having dusted, the most quickly cool down, and its surface is carried out grinding process；B. choosing manganese alloy steel is raw material, utilizes clasp to be fixed on wheel hub by rim after processing rim, and heating.C. after b step completes, to rim surface spraying/roller coating prime paint, prime paint is white fused alumina sand grains, makes roughness reach 8 ~ 15 μm, and is dried 30 minutes；D. at prime paint surface spraying/roller coating floating coat paint after step c completes, described floating coat paint is aliphatic polyurethane glass flake paint, paints three times polyurethane coating varnishes of spraying at floating coat continuously after being dried 0.5-1.5 hour.The coating layer thickness of described prime paint is 100 μm-120 μm.The coating layer thickness of described floating coat paint be the coating layer thickness of polyurethane coating varnish described in 130 μm-150 μm be 130 μm-150 μm
The coating system that the present invention uses is compared, and can form the paint film of one layer of application at wheel surface, in long-term walking process, rub paint film before this, and can effectively extend the service life of wheel, and saved Financial cost.Secondly, the present invention uses assembled vehicle wheel, saves Financial cost.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
