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 GH4169 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 GH4169 alloys of the present invention, its technology
Scheme is comprised the following steps：
GH4169 alloys are cutting into into bar according to certain specification；GH4169 alloy bar materials are heated to into 1050 ± 10 DEG C
Insulation, charging temperature≤750 DEG C；After heat penetration, GH4169 alloy bar materials are placed on forcing press, forging hammer is driven to GH4169 alloys
Bar carries out jumping-up to preliminary dimension；GH4169 alloy blanks after jumping-up are put in punching die, and is placed on pressure together
Under machine, the outer wall of punching die has for fixed dovetail groove, prevents punching die and GH4169 alloy blanks from moving with forging hammer,
Spacing disc is placed with punching die, the disc according to the height of GH4169 alloy blanks design, make GH4169 alloy blanks with
Punching die upper end is concordant, it is ensured that forging hammer will not be collided with punching die in punching；In above the GH4169 alloy blanks
The heart places suitable drift, drives forging hammer to push drift, drift is pressed in GH4169 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 are the contact area of blank and drift, and H is the depth that drift is pressed into blank；GH4169 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 GH4169 alloys
The external diameter of blank is consistent, and GH4169 alloy blanks are just placed in spacing hole；GH4169 alloy blanks are placed on after drift is inverted
Endoporus on, drive forging hammer push drift, by drift be pressed into GH4169 alloy blanks in；Forging hammer is lifted, is put on drift
One cushion block, then drive forging hammer to push cushion block, GH4169 alloy blanks to be washed open, cushion block, drift and punching core material are together from leakage
Spill in disk, complete GH4169 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 GH4169 alloys of the present invention, by designing punching die, it is therefore prevented that base
Expect that end face draws the defects such as material, deformation, and blank need not carry out round as a ball shaping operation, reduce operating procedure and reduce 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.
