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 GH188 alloys.
Background technology
High cylinder ring is the revolving body parts that the fields such as Aero-Space often use, and the forging height compares 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 now state-of-the-art journal axle is two-way 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 in a mold to height ring, it is ensured that is not in that end face draws the defects such as material, deformation in punching, improves forging
Part quality.
To solve above-mentioned technical problem, the enclosed hole-punching method of the high cylinder ring of GH188 alloys of the present invention, its technical side
Case is comprised the following steps：
GH188 alloys are cutting into into bar according to certain specification；GH188 alloy bar materials are heated to into 1180 ± 10 DEG C,
It is incubated by 0.8min/mm, charging temperature≤800 DEG C；After heat penetration, GH188 alloy bar materials are placed on forcing press, drive forging hammer pair
GH188 alloy bar materials carry out jumping-up to preliminary dimension；GH188 alloy blanks after jumping-up are put in punching die, and together
Under being placed on forcing press, the outer wall of punching die has for fixed dovetail groove, prevents punching die and GH188 alloy blanks with forging
Hammer movement, is placed with spacing disc in punching die, the disc is designed according to the height of GH188 alloy blanks, makes GH188 alloy preforms
Material is concordant with punching die upper end, it is ensured that forging hammer will not be collided in punching with punching die；On GH188 alloy blanks
Suitable drift is placed at center, drives forging hammer to push drift, and drift is pressed in GH188 alloy blanks, is then taken out, and forging hammer drives
PowerWherein, σSFor Real Flow Field stress under corresponding deformation temperature and speed, μ is friction
Factor, S is the contact area of blank and drift, and H is the depth that drift is pressed into blank；GH188 alloy blanks are taken out and are placed on
On drain cap, the outer wall of drain cap also has for fixed dovetail groove, the upper end spacing hole of drain cap, spacing hole size and GH188 alloys
The external diameter of blank is consistent, and GH188 alloy blanks are just placed in spacing hole；GH188 alloy blanks are placed on after drift is inverted
On endoporus, drive forging hammer to push drift, drift is pressed in GH188 alloy blanks；Forging hammer is lifted, one is put on drift
Cushion block, then drive forging hammer to push cushion block, GH188 alloy blanks to be washed open, cushion block, drift and punching core material leak together from drain cap
Go out, complete GH188 alloy rings punchings.
Compared with prior art, beneficial effects of the present invention are as follows：
The enclosed hole-punching method of the high cylinder ring of GH188 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 also can prevent from occurring rushing during punching wait partially error, improve the consistent of blank
Property.
