Description
Technical field
The present invention relates to a kind of production technology, more particularly to a kind of flange production technology.
Background technology
Flange is important conduit coupling, is widely used.At present, flange in the fabrication process, typically pole blanking
Afterwards, directly machine（Lathe process, milling machine processing etc.）Form, but such processing method is so that turning, milling time are long, labor
Dynamic cost is big and spillage of material is very serious, accounts for 40%-50%.Due to prolonged deep processing, the residual stress of product is more, material
The hardness of material is high, directly affects the mechanical property and performance of material.
Meanwhile, flange stock is typically first used drilling machine central bore by current flange processing, then rough turn with engine lathe
Interstitial hole and cylindrical, then uses numerically controlled lathe smart car, is finally drilled with common driller.Due to wanting car to fall endoporus, cutting output is big, material
Material loss is more.Because flange bad oxide skin is not gone, dust is more, and method bad case hardness is big, in turning, it is necessary to first go up common in-vehicle
Bed, then upper numerically controlled lathe, lathe tool abrasion are big, service life and the precision reduction of lathe tool；Meanwhile, also reduce the use longevity of lathe
Life, directly affects the dimensional accuracy and surface smoothness of flange.
The content of the invention
To overcome above-mentioned deficiency, it is an object of the present invention to provide a kind of flange production technology, the technique can improve flange forging stock
Efficiency, reduces spillage of material, while the flange size for producing is precisely, surface smoothness is high.
The solution of the present invention is as follows：A kind of flange production technology, including flange forging stock and blank cutting forming, its feature exist
In,
Described flange forging stock is comprised the following steps：
After a, raw material pole blanking, heated into electric furnace, heating-up temperature is 700 DEG C -1150 DEG C；Heating uses four
Stage heating means, first stage heating-up temperature is 700 DEG C -880 DEG C, and the time is 10-15s；Second stage heating-up temperature is
800 DEG C -900 DEG C, the time is 20-32s；Phase III heating-up temperature is 900-1000 DEG C, and the time is 12-20s；Fourth stage
Heating-up temperature is 1010-1150 DEG C, and the time is 15-50s；
Raw material pole after b, heating is put into forging of punching machine into required flange shape after being cooled to room temperature；
C and then place into friction press, it is cold extrusion shaped to flange basic size on mould；Again through solid solution heat
Treatment, forms flange blank；
Described blank cutting forming is comprised the following steps：
D, using punch press to flange stock punching；
E, the flange base after punching and sweeping away is partially placed into pickling 20-30min in the salt pickling tube that concentration is 28-30%,
Descale；
Flange base after f, pickling is put into numerically controlled lathe, and first a rough turn knife is cylindrical and endoporus, then the knife of smart car one is cylindrical and interior
Hole；
G, finally with numerical control drilling machine bore exit orifice, flange machine-shaping.
Further, described solution heat treatment is comprised the following steps:
Step one：Solid solution after flange base is heated into 1010~1150 DEG C, is incubated 1-2h；
Step 2：Then with the cooling rate of 1-2.5 DEG C/min, after flange base is cooled into 640~680 DEG C, after insulation
2-3h；
Step 3：Again with the programming rate of 6-10 DEG C/min, after flange base is warming up into 700~750 DEG C, 1-2h is incubated；
Step 4：With the cooling rate of 1-2.5 DEG C/min, after flange base is cooled into 440~460 DEG C, 2-3h after insulation；
Step 5：Again with the programming rate of 4-8 DEG C/min, after flange base is warming up into 500~540 DEG C, 5-10min is incubated
Water quenching afterwards, shaping.
The present invention first carries out heating for multiple times cooling treatment so that raw material pole table in the flange forging stock stage to raw material pole
Face and internal performance are uniform so that the extrusion forming of postorder is more stablized；By multiple solution heat treatment, the grain structure of forging stock
Uniformly, hardness is low, good toughness, surrender degree is high, tension is strong, elongation percentage reaches requirement, and flange forging stock efficiency improves 300%, material energy
Accomplish zero loss.
The present invention, by pickling, reduces the hardness of flange blank in the blank cutting forming stage；Because punch press sweeps away portion
Dividing can be processed into small flange, and material obtains punching point and utilizes；Meanwhile, after descale, flange base can not use engine lathe,
Digit Control Machine Tool is directly gone up, production equipment is saved, operating efficiency more than 80% is improved.
