Description
Technical field
The present invention relates to a kind of hole-punching method, the more particularly to enclosed hole-punching method of the high cylinder ring of GH99 alloys.
Background technology
High cylinder ring is the revolving body parts that the fields such as Aero-Space often use, and the forging height is compared with wall thickness
Greatly, generally using roll forming.Rolling generally refers to radial rolling, is reduction wall thickness, makes the process that internal-and external diameter is grown up, height
Vary less；Even if state-of-the-art journal axle is two-way now rolls loop technique, also height can only be reduced by cone roller, and can not be good
Control height is grown up.So in base, the height of blank to be typically designed to the height of equal or slightly larger than ring, then
For high cylinder ring, blank end face is easily caused in punching and draws the defects such as material, deformation, affect forging quality.At present simultaneously
Without good control method.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of method of employing enclosed punching, by designing enclosed perforating die
Tool, is punched out to height ring in a mold, it is ensured that is not in that end face draws the defects such as material, deformation in punching, is improved forging
Part quality.
To solve above-mentioned technical problem, the enclosed hole-punching method of the high cylinder ring of GH99 alloys of the present invention, its technical side
Case is comprised the following steps：
GH99 alloys are cutting into into bar according to certain specification；GH99 alloy bar materials are heated to into 1130 ± 10 DEG C of guarantors
Temperature, charging temperature≤700 DEG C；After heat penetration, GH99 alloy bar materials are placed on forcing press, drive forging hammer to enter GH99 alloy bar materials
Row jumping-up is to preliminary dimension；GH99 alloy blanks after jumping-up are put in punching die, and is placed under forcing press together, punching
The outer wall of mould has for fixed dovetail groove, prevents punching die and GH99 alloy blanks from moving with forging hammer, in punching die
Spacing disc is placed with, the disc is designed according to the height of GH99 alloy blanks, makes to hold level with both hands on GH99 alloy blanks and punching die
Together, it is ensured that forging hammer will not be collided with punching die in punching；Suitable drift is placed at center on GH99 alloy blanks,
Drive forging hammer to push drift, drift is pressed in GH99 alloy blanks, is then taken out, forging hammer driving force Wherein, σSFor Real Flow Field stress under corresponding deformation temperature and speed, μ is friction factor, and S is base
The contact area of material and drift, H are the depth that drift is pressed into blank；GH99 alloy blanks are taken out and are placed on drain cap, drain cap
Outer wall also have for fixed dovetail groove, the upper end spacing hole of drain cap, the external diameter one of spacing hole size and GH99 alloy blanks
Cause, GH99 alloy blanks are just placed in spacing hole；It is placed on after drift is inverted on the endoporus of GH99 alloy blanks, drives forging hammer
Drift is pushed, drift is pressed in GH99 alloy blanks；Forging hammer is lifted, a cushion block is put on drift, then is driven forging hammer
Cushion block is pushed, GH99 alloy blanks are washed open, cushion block, drift and punching core material are spilt from drain cap together, complete GH99 alloys
Ring punching.
Compared with prior art, beneficial effects of the present invention are as follows：
The enclosed hole-punching method of the high cylinder ring of GH99 alloys of the present invention, by designing punching die, it is therefore prevented that blank
End face draws the defects such as material, deformation, and blank need not carry out round as a ball shaping operation, reduces operating procedure and reduces operation hardly possible
Degree, improves production efficiency.Blank is deformed in a mold, the improvement of its presentation quality, and billet size precision and
Batch stability is improved.The spacing hole of drain cap can also prevent from occurring rushing during punching wait partially error, improve the consistent of blank
Property.

With reference to the accompanying drawings and detailed description the present invention is described in further detail.
Fig. 1 is the structural representation of punching die.
Fig. 2 is the structural representation of disc.
Fig. 3 is drift press-in blank process schematic.
Fig. 4 is to be pressed into blank process schematic after drift is inverted.

Specific embodiment
The enclosed hole-punching method for implementing the high cylinder ring of GH99 alloys of the present invention needs to provide forge furnace, pressure
The equipment such as machine, mechanical hand.Its specific embodiment：
The main chemical elements content (percentage by weight) of the GH99 alloys is：C content≤0.08%, containing Cr amount 17.0%
～20.0%, 5.0%～8.0% is measured containing Co, measure 1.7% containing W amounts 5.0%～7.0%, containing Mo amounts 3.5%～4.5%, containing Al
～2.4%, 1.0%～1.5% is measured containing Ti, measure containing Fe amounts≤2.0%, containing B amounts≤0.005%, containing Ce amounts≤0.02%, containing Mg
≤ 0.01% ,≤0.4%, si content≤0.5%, P content≤0.015% are measured containing Mn ,≤0.015%, balance of Ni is measured containing S.
The step of this method, is as follows：
GH99 alloys are cutting into into bar according to certain specification；GH99 alloy bar materials are heated to into 1130 ± 10 DEG C of guarantors
Temperature, charging temperature≤700 DEG C；After heat penetration, GH99 alloy bar materials are placed on forcing press, drive forging hammer to enter GH99 alloy bar materials
Row jumping-up is to preliminary dimension；GH99 alloy blanks 4 after jumping-up are put in punching die 1, and is placed under forcing press together, rush
The outer wall of punch die 1 has for fixed dovetail groove, prevents punching die 1 and GH99 alloy blanks 4 from moving with forging hammer, such as Fig. 1
It is shown, spacing disc 2 is placed with punching die 1, the disc 2 is designed according to the height of GH99 alloy blanks 4, makes GH99 alloy preforms
Material 4 is concordant with 1 upper end of punching die, it is ensured that forging hammer will not be collided with punching die 1 in punching；On GH99 alloy blanks 4
Suitable drift 3 is placed at the center in face, is driven forging hammer to push drift 3, drift 3 is pressed in GH99 alloy blanks 4, Ran Houqu
Go out, forging hammer driving forceWherein, σSShould for Real Flow Field under corresponding deformation temperature and speed
Power, μ are friction factor, and S is the contact area of blank and drift, and H is the depth that drift is pressed into blank；By GH99 alloy blanks 4
Take out and be placed on drain cap 5, the outer wall of drain cap 5 also has for fixed dovetail groove, the upper end spacing hole of drain cap 5, spacing hole chi
Very little consistent with the external diameter of GH99 alloy blanks 4, GH99 alloy blanks 4 are just placed in spacing hole；It is placed on after drift 3 is inverted
On the endoporus of GH99 alloy blanks 4, drive forging hammer to push drift 3, drift 3 is pressed in GH99 alloy blanks 4；Forging hammer is lifted
Rise, a cushion block 6 is put on drift 3, then drives forging hammer to push cushion block 6, GH99 alloy blanks 4 are washed open, cushion block 6, drift 3
