Description
Technical field
The invention belongs to plastic forming technology fields, are related to the manufacture of special-shaped product, in particular to nuclear fusion stack magnet branch
The i shaped steel looping mill rolling manufacturing method of support.
Background technique
The i shaped steel of nuclear fusion stack magnet support is a kind of be 'Gong' font section strip shaped piece, wall thickness compared with
Thin, length is longer.Material is stainless steel, is required very low temperature resistant, high pressure, anticorrosive, internal low defect, comprehensive mechanical property
It is high.
The mode that the solid strip shape Forging of forging is usually used in i shaped steel classical production process forms, and then leads to again
It crosses mach mode and falls internal extra surplus；Or formed by the way of being forged to flute profile forging, it is another subsequently through turnning and milling
Extra surplus on one side.When being manufactured using these modes, material internal machine direction can be cut off in machining and be reduced
Its comprehensive performance, and since machining allowance is too big, need a large amount of time to be machined out, while also resulting in the wave of raw material
Take.
Summary of the invention
The present invention is to solve material internal machine direction existing for the i shaped steel of conventional method forging and can add in machine
Working hour is cut off and reduces its comprehensive performance, and since machining allowance is too big, a large amount of time is needed to be machined out, together
When the technical issues of also resulting in the waste of raw material.
In order to solve the above technical problems, the present invention uses following technical proposal:
The i shaped steel specially-shaped method of nuclear fusion stack magnet support, the mold that it is used is by home roll mould and core roller die two
It is grouped as, this method is divided into three steps:
Step 1: circular material blank prepares: first forging and pressing Heating Steel Ingots to 1150 DEG C to change its structural state, in soldering
Portion's defect, and circular material blank is made through punching, reaming process, section ruler when circular material blank sectional dimension and i shaped steel form
Very little to be consistent, circular material blank materials are the conjunction material of more than one piece i shaped steel；
Step 2: i shaped cross section looping mill rolling manufactures: by the assembly of home roll mould on looping mill home roll, core roller die being assembled in looping mill
On core roller, home roll mould, core roller die form boss horizontal alignment；Circular material blank is heated to 1150 DEG C, is put after keeping the temperature enough time
It sets on looping mill rolling machine worktable, starts looping mill, home roll mould and core roller die and circular material blank internal and external circumference face contact, with looping mill rolling
Rotation, the feeding of owner's roller, circular material blank inside and outside circle circumferential surface forms core roller die and home roll mould correspondingly-sized piece by piece, until core roller die
It is fully fed in place with home roll mould, i shaped cross section molding finishes, and looping mill rolling is completed；
Step 3: sub-material is straightened: after i shaped cross section looping mill rolling, i shaped cross section ring being divided into more than one piece arc by arc length
Section, then the segmental arc that every separates is straightened respectively, obtain the i shaped steel of strip.
The heat preservation enough time be in order to by homogeneous heating inside I-shaped steel blank, it is thick according to I-shaped Steel material and blank
Degree calculates for 0.5 to 1 minute by every millimeter.
By adopting the above technical scheme the utility model has the advantages that
Shaping speed of the present invention is fast, dimensional accuracy is high, machining allowance is small, manufacture difficulty substantially reduces, mechanical performance and use
Service life improve, have low-temperature resistance, high pressure and anticorrosion properties and processing cost it is low.

Specific embodiment
In conjunction with above-mentioned attached Example, the present invention is further described.
The i shaped steel specially-shaped method of nuclear fusion stack magnet support, the mold that it is used is by home roll mould 1 and core roller
2 two parts of mould composition, this method are divided into three steps:
Step 1: circular material blank 3 prepares: first forging and pressing Heating Steel Ingots to change its structural state, soldering to 1150 DEG C
Internal flaw, and circular material blank 3, cutting when 3 sectional dimension of circular material blank and i shaped steel form is made through punching, reaming process
Face size is consistent, and 3 materials of circular material blank are the conjunction material of more than one piece i shaped steel；
Step 2: i shaped cross section looping mill rolling 4 manufactures: by the assembly of home roll mould 1 on looping mill home roll, core roller die 2 being assembled in ring
On milling train core roller, home roll mould 1, core roller die 2 form boss horizontal alignment；Circular material blank 3 is heated to 1150 DEG C, heat preservation 3-5 is small
When after be placed on looping mill rolling machine worktable, start looping mill, home roll mould 1 and core roller die 2 connect with 3 inside and outside circle circumferential surface of circular material blank
Touching, with the rotation of looping mill home roll, feeding, 3 inside and outside circle circumferential surface of circular material blank forms core roller die 2 piece by piece and home roll mould 1 is corresponding
Size, until core roller die 2 and home roll mould 1 are fully fed in place, i shaped cross section molding is finished, and looping mill rolling is completed；
Step 3: sub-material is straightened: after i shaped cross section looping mill rolling, i shaped cross section ring 4 being divided into more than one piece arc by arc length
Section, then the segmental arc that every separates is straightened respectively, obtain the i shaped steel of strip.
