Description
Technical field
The present invention relates to forging technology field, be specifically related to the rolloff molding manufacturer of the I-shaped forging of a kind of magnet support
Method.
Background technology
I-shaped forging is the critical component of ITER project magnet support, and material is 316LN austenitic stainless steel, due to shape
Shape is irregular, and length is longer, thinner thickness, and grain size requires higher, and forging exists bigger difficulty.Conventional manufacture method has
Three kinds below: method one: extruded mode carries out the production of I-shaped forging, method two: design specialized mould rolls
Make type, method three: directly use mould forging, then carry out machining.But due to the super rule of this I-shaped product size
Lattice, existing extrusion equipment is difficult to meet dimensional requirement, simultaneously because product quantity is few, the rolling mold of design specialized, transformation
Rolling equipment puts into relatively big, causes production cost higher, directly forges that then machining cost is higher and production efficiency is relatively low.
Summary of the invention
For above-mentioned weak point of the prior art, invention aims to provide the rolloff of the I-shaped forging of a kind of magnet support
Moulding manufacture method, the allowance of its processed finished products is little, even tissue, and whole section deformation is abundant, and crystal grain refines, and shape is advised
Then, forging quality is high, and production efficiency is high.
For solving above-mentioned technical problem, the procedure of processing of invention is as follows:
One, blank processing: alloy pig is heated to 1150-1180 DEG C, uses the operations such as jumping-up, punching, reaming to produce
Preform,
Two, roll cyclization: sent into by preform and heating furnace carries out heat treated, heating-up temperature to 1150-1180 DEG C,
Take out the blank after heating, be placed on ring rolls, king roller lining and core roller lining be respectively fitted on king roller and core roller, base
The upper and lower end face of material uses cone roll-in to live, and starts ring rolls, starts to rotate, roll under the drive of king roller and core roller,
After reaching size, close ring rolls, obtain looped I-shaped ring,
Three, I-shaped forging molding: above-mentioned I-shaped ring vertically (short transverse) is cut, then utilizes core
Rod pierces into ring endoporus, starts and presses under hydraulic press, by multiple rotary, ring is gradually launched into I-shaped forging,
Four, I-shaped forging smoothing processes: put in flat-die by above-mentioned I-shaped forging, by horizontal direction (length side
To) on smooth for several times, i.e. can get the I-shaped forging of finished product.
In described step 3 cutting I-shaped ring vertically (short transverse), its kerf width is 150-
300mm。
There is advantages that the ring forging allowance that the method is produced is little, even tissue, whole section
Facial disfigurement is abundant, and crystal grain refines, regular shape, and forging quality is high, and production efficiency is high.

Detailed description of the invention
Below in conjunction with the accompanying drawing in inventive embodiments, the technical scheme in inventive embodiments is carried out clearly and completely
Describe.
Detailed description of the invention one:
Referring to Fig. 1-Fig. 7, the procedure of processing of this detailed description of the invention is as follows:
One, blank processing: alloy pig is heated to 1150 DEG C, uses hydraulic forging press to carry out jumping-up, utilizes punch press to carry out
The operation such as punching, reaming produces preform,
Two, cyclization is rolled: sent into by preform and heating furnace carries out heat treated, heating-up temperature to 1150 DEG C, take out
Blank 1 after heating, is placed on ring rolls, king roller lining 3 and core roller lining 5 is respectively fitted on king roller 2 and core roller 4,
The upper and lower end face of blank 1 uses cone roller 6 to push down, and starts ring rolls, starts to rotate, carry out under the drive of king roller 2 and core roller 4
Rolling, in the operation of rolling, first increases the active force of axial roll, then amplify cerclage spread phenomenon so that blank forms twin drum
Type, after reaching size, closes ring rolls, obtains looped I-shaped ring 7,
Three, I-shaped forging molding: above-mentioned I-shaped ring 7 vertically (short transverse) is cut, kerf width
For 200mm, then utilize plug to pierce into ring endoporus, start and press under hydraulic press, by multiple rotary, gradually ring is launched into
I-shaped forging,
Four, I-shaped forging smoothing processes: put in flat-die by above-mentioned I-shaped forging, by horizontal direction (length side
To) upper five smoothings, i.e. can get the I-shaped forging of finished product.
The operation principle of this detailed description of the invention: the jumping-up operation of employing, it is possible to improve the as-cast structure of steel ingot, it is not necessary to
Additionally increase blanking mold, utilize and spread phenomenon during ring rolling, conscious during looping mill rolling first increase axially
The active force of roll, that amplifies looping mill rolling spreads phenomenon, makes blank form twin drum type, then carries out final looping mill rolling, obtains I-shaped
The ring in cross section, then cuts open I-shaped annular forging piece along short transverse, ring is flattened, finally utilizes mould to carry out school
Flat.
This detailed description of the invention has the advantages that the ring forging allowance using the method to produce is little, group
Knitting uniformly, whole section deformation is abundant, and crystal grain refines, regular shape, and forging quality is high, and production efficiency is high.
Detailed description of the invention two:
The procedure of processing of this detailed description of the invention is as follows:
