Description
Technical field
The present invention relates to a kind of manufacturing methods of steel component, more particularly, to a kind of suspension insulator spherical shape and flute profile
The manufacturing method of steel cap.
Background technique
Steel cap is the important component on electric porcelain insulator used for transmission line, it will not only have higher mechanical strength, but also
Weight is light, can be corrosion-resistant.The safe operation of steel cap machine security reliability effect transmission line of electricity.Steel cap mostly metal material at present
Material is fabricated.Its manufacturing method mainly has: first is that being poured with spheroidal graphite cast-iron or malleable cast iron, this casting method can not
The defects of slag inclusion inside presence, stomata, shrinkage porosite and trachoma for avoiding, seriously affects the mechanical performance quality of steel cap, using depositing
In security risk, while cast article weight is big, and rough surface, production efficiency is low, and manufacturing cost is high, large labor intensity, environment
Heavy contamination；It is all fabricated using forging second is that also having, although forged steel cap appearance and internal soundness are good, mechanical performance
Height, safety in operation is good, but forged steel cap technics comparing is more, and processing efficiency is not high, and manufacturing cost is high.
Summary of the invention
Aiming at the problem that in the presence of the manufacture of above-mentioned suspension insulator steel cap in the prior art, the invention proposes a kind of steel
Not only manufacture efficiency is high for cap, high-quality, and the spherical manufacturing method with channel-section steel cap of suspension insulator that manufacturing cost is low.
The technical problem to be solved in the present invention is adopted the technical scheme that: a kind of suspension insulator is spherical and channel-section steel
The manufacturing method step of cap is:
A, steel cap is divided into two part of cap head and cap body, carries out blanking respectively by cap head and cap body expansion shape and size,
B, flute profile cap head is produced with steel plate cutting and process for stamping, will warm up 1000-1100 DEG C of forging material forging die method system
Spherical cap head out,
C, cap body blanking steel plate is produced with punching machine process for stamping in cone to and is had the cap body of flange, the cap body top
It is upper that cap head positioning boundary line is equipped with by scribing line,
D, bending being carried out with the flaring of punching machine punching press cap body lower end and forming flanging, lower end aperture is made to extend inwardly to form arc-shaped contracting
Mouthful,
F, cap head and cap body are attached separately on model both ends, model are closed, make the positioning boundary line in cap head alignment cap body,
G, the electric current and voltage for regulating CO2 shield welder, with CO2 shield welder tool hand by cap head and cap body from
Dynamic welding, keeps cap head and cap body solder bond integral,
H, again by steel cap Shot Blasting obtained above, then surface heat zinc-plated processing is carried out.
The present invention produces cap body and cap head using full punching machine process for stamping respectively, then is welded and made by carbon-dioxide arc welding
It is whole at channel-section steel cap, while cap body is produced using punching machine process for stamping and spherical caps small in size are produced using hot-forging die method
Head combines method, then spherical steel cap entirety is made by carbon-dioxide arc welding welding, this entirely or essentially to take punching machine
Process for stamping produces flute profile and spherical steel cap has the advantage that compared with the prior art produces the method for steel cap
1, high production efficiency, environment friendly and pollution-free, production environment is good, can form large-scale production,
2, steel cap tensile strength is high, and corrosion-resistant and shock resistance, compared with cast steel cap, tensile strength improves 30% or more,
3, the defects of steel cap interiors of products is without slag inclusion, stomata, shrinkage porosite and trachoma, without welding slag, fracture and flanging, product makes for outside
It is safe with high reliablity, operation of power networks,
4, steel cap surface smooth and beautiful appearance, it is light-weight, save material, lower production costs.
