Day by day increase, along with the progress of science and technology, industrial machine to high-performance, high parameter, maximization development trend obvious, the most right
The cheese forging little with forging big centre, two, during the class cheese forging that in prior art, the forging big centre of diameter, two is little, one
As be swaged into cake, such forging process for fuel surplus is big, and waste of raw materials is serious, and it is long to machine man-hour, and material cost is many, labor
Power waste is big.
Therefore it provides the mould Forging Technology of a kind of dumbbell class cheese forging, to can be by processing technique is carried out
Improve, forged by cheese model method, improve forging precision, when reducing forging, produce fracture, make forging smooth surface without
Hammering, reduces raw-material weight, lowers production cost, just becomes the problem that those skilled in the art need solution badly.
Summary of the invention
It is an object of the invention to provide the mould Forging Technology of a kind of dumbbell class cheese forging, to passing through processing
Technique improves, and is forged by cheese model method, improves forging precision, produces fracture, make forging table when reducing forging
Face is smooth without hammering, reduces raw-material weight, lowers production cost.
For solving technical problem described in background technology, the present invention by the following technical solutions:
A kind of mould Forging Technology of dumbbell class cheese forging, its Forging Technology process is:
Step 1, forging heating technique: heated by five sections of examinations by forging before carrying out forging, 350 DEG C of constant temperature keep about
About 3 5h, until material temperature uniformly after can continue heating, be incubated 2 3h during middle temperature 850 DEG C, after be heated to 1100 as quickly as possible
1180 DEG C of forging temperatures, are incubated 5 6h and come out of the stove forging.
Step 2, mould forging step: mould is made up of Preform Die and mould, and respectively Preform Die with become
Carry out forging in mould to make:
(1) Preform Die forging: it is the big platform that is relatively large in diameter that Preform Die is, when forging in blocker jumping-up
Method forges a great circle, by jumping-up forging method when jumping-up forges, is divided into 35 times and carries out jumping-up during jumping-up, and at jumping-up
The slow method of Shi Caiyong mono-upsetting one carries out jumping-up, forges a big toroidal of this forging in Preform Die.
(2) mould forging: mould is made up of core rod and outer die casing two parts:
Core rod is forging reverse shape, is longitudinally cut from centre by core rod by electric saw, be equally divided into two portions during forging
Divide, and outer die casing is enclosed within outside core rod；
Shaping mould forging other end great circle put into immediately by forging after having been forged one end, after take off outer die casing, separately
Core rod, takes out forging.
Preferably, during jumping-up in described step 2, use repeatedly jumping-up to advance, and push-in stroke be 50 70mm every time,
Forged by the most a small amount of jumping-up propulsion mode, improve the precision of forging, it is to avoid cause forging local owing to propelling is excessive
Fracture.
Preferably, the block that the Preform Die forging in described step 2 is to be tried one's best when forging with mould, keep forging
Time forging temperature higher than final forging temperature, and final forging temperature is set to 900 950 DEG C, makes forging temperature higher than final forging temperature, it is possible to protect
Hold forging and be in optimal mecystasis, reduce forging difficulty.
The invention has the beneficial effects as follows:
1), by processing technique is improved, forged by cheese model method, improve forging precision, reduce forging
Produce fracture when making, make forging smooth surface without hammering.
