Abstract
The invention relates to a packaging method of a high-voltage frequency converter power unit which comprises a power unit body and a shell. The characteristics lie in that the shell is a seamless steel pipe, and the power unit body is molded into a cylindrical power unit module through a cylindrical injection mold; then the cylindrical power unit module integrally penetrates through a casing of the seamless steel pipe, a cold-drawing diameter shrinkage mold is set, an inner bore of the cold-drawing diameter shrinkage mold is composed of a gradually shrinking front segment at the front part and a rear segment with the diameter being equal at the rear part, then overall stretching diameter shrinking is performed through the cold-drawing diameter shrinkage mold, and the inner diameter of the shell and an excircle of the cylindrical power unit module realize close fitting on the whole.
Description
Technical field
The present invention relates to a kind of method for packing of high voltage transducer power unit, belongs to high voltage converter field.
Background technology
Seamless steel pipe is a kind of very important economic section section bar, is known as the blood vessel of industry, and it extensively should
For every field such as oil, chemical industry, Aero-Space, building, boiler etc., occupy very important position in national economy
Put, as seamless steel pipe has structure excellent, lower-cost advantage, as high voltage transducer power unit application conditions are disliked
Bad, such as open air is exposed to the weather and is drenched with rain, and needs its housing to have the impaired fracture of good performance guarantee high voltage transducer power unit,
The excellent performance protection high voltage transducer power unit of seamless steel pipe, seamless steel pipe fluidization process is elastic and plastic deformation process, very
Real boundary condition is extremely complex, can effectively prevent high voltage transducer power unit from being destroyed by the external world.
In the produce reality of seamless steel pipe be by real pipe still or steel ingot perforation axle make the steel pipe of empty also section.Cause
The difference of unit, product technology require difference, and technological process is also not quite similar, but prepare before typically all including breast, heat, change
Several links such as thorough, finishing, machining and inspection packaging.Basic working procedure is for perforation and changes pipe.Change before prepare should include check,
Cleaning, cut-out, the fixed operation such as also.The breast link processed of steel pipe includes boring a hole, extends, (tension force subtracts for latex dust, expansion, sizing or tube reducing
Footpath) etc. operation.Obviously complete heat even must include in seamless steel pipe technical process it is thick, in, smart ancestral H parts could obtain institute
The heat breast production tube of needs.Steel-tube finishing process includes disconnected rope, cooling, heat treatment, aligning, Pipe Cutting, steel pipe mechanical processing, inspection
With packaging etc. finishing procedure, its objective is ensure tubing finally meet the technical requirements and technical standard dispatched from the factory, by seamless steel pipe
Premium properties be applied to high voltage converter housing.
The content of the invention
In view of above-mentioned technical problem, of the invention that seamless steel pipe is applied to high voltage converter, a kind of high voltage frequency converter power
The method for packing of unit, including power cell body, housing, it is characterised in that the housing is seamless steel pipe, by the power
Cell body is molded into cylindrical power unit module by column type injection mold.Again by the cylindrical power unit module
Integrally through a cold-drawn stem reducing mould in the casing of seamless steel pipe, is arranged, the endoporus of cold-drawn stem reducing mould is tapered by front portion
The isometrical back segment in leading portion and rear portion is constituted, and then carries out integrally stretching undergauge, housing inner diameter and circle by a group cold-drawn stem reducing mould
The cylindrical overall realization of cylindricality power unit module is brought into close contact.
The injection mold is the cylinder with different-diameter, and casting resin is poured in the injection mold, then by institute
State high voltage transducer power unit to be put in injection mold, cylindrical power unit module is formed after injected plastics material is cooled down, will
Column type power unit module is taken out from injection mold.The external diameter phase of the internal diameter of injection mold and high voltage transducer power unit
Closely, high voltage transducer power unit can be made to be put in the injection mold.The cold-drawn reducing die also includes being arranged on leading portion
Interlude and back segment between, the external diameter of the interlude are more than leading portion external diameter and are less than back segment external diameter.

Through in the casing of seamless steel pipe, by 300 solid drawn tube of cold-drawing technology, wherein cold-drawing technology 300 includes setting one to body
Individual cold-drawn stem reducing mould, the endoporus of cold-drawn stem reducing mould are made up of the isometrical back segment in anterior tapered leading portion and rear portion, Ran Houtong
Crossing group cold-drawn stem reducing mould carries out integrally stretching undergauge, and housing inner diameter overall realization cylindrical with cylindrical power unit module is tight
Laminating.
The injection mold is the cylinder with different-diameter, and casting resin is poured in the injection mold, then by institute
State high voltage transducer power unit to be put in injection mold, cylindrical power unit module is formed after injected plastics material is cooled down, will
Column type power unit module is taken out from injection mold.The external diameter phase of the internal diameter of injection mold and high voltage transducer power unit
Closely, high voltage transducer power unit can be made to be put in the injection mold.The cold-drawn reducing die also includes being arranged on leading portion
Interlude and back segment between, the external diameter of the interlude are more than leading portion external diameter and are less than back segment external diameter.
