Description
Technical field
The present invention relates to a kind of hole-punching method, the more particularly to enclosed hole-punching method of GH907 alloys cylinder ring high.
Background technology
Cylinder ring high is the revolving body parts that the fields such as Aero-Space often use, and 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 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 cylinder ring high, blank end face is easily caused in punching and draws the defects such as material, deformation, influence forging quality.At present simultaneously
There is no 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 use 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, improves forging
Part quality.
In order to solve the above technical problems, the enclosed hole-punching method of GH907 alloys cylinder ring high of the present invention, its technical side
Case is comprised the following steps：
GH907 alloys are cutting into bar according to certain specification；GH907 alloy bar materials are heated to 650 ± 10 DEG C, are pressed
(0.4~0.5) min/mm is incubated, then is warming up to 1040 ± 10 DEG C, by (0.4~0.5) min/mm insulations, charging temperature≤650
℃；After heat penetration, GH907 alloy bar materials are placed on forcing press, drive forging hammer to carry out jumping-up to pre- scale to GH907 alloy bar materials
It is very little；In putting the GH907 alloy blanks after jumping-up into punching die, and it is placed under forcing press together, the outer wall of punching die has
For fixed dovetail groove, prevent punching die and GH907 alloy blanks from being moved with forging hammer, spacing pad is placed with punching die
Disk, the disc is designed according to the height of GH907 alloy blanks, makes GH907 alloy blanks concordant with punching die upper end, it is ensured that forging
Hammer will not be collided in punching with punching die；Suitable drift is placed at center on GH907 alloy blanks, drives forging hammer
Drift is pushed, drift is pressed into GH907 alloy blanks, then taken out, forging hammer driving force
Wherein, σSIt is Real Flow Field stress under corresponding deformation temperature and speed, μ is friction factor, and S is the contact surface of blank and drift
Product, H is the depth that drift is pressed into blank；GH907 alloy blanks are taken out and are placed on drain cap, the outer wall of drain cap also has for solid
Fixed dovetail groove, the upper end spacing hole of drain cap, spacing hole size is consistent with the external diameter of GH907 alloy blanks, GH907 alloy blanks
Just it is placed in spacing hole；It is placed on after drift is inverted on the endoporus of GH907 alloy blanks, drives forging hammer to push drift, will be rushed
In head press-in GH907 alloy blanks；Forging hammer is lifted, a cushion block is put on drift, then drive forging hammer to push cushion block, will
GH907 alloy blanks are washed open, and cushion block, drift and punching core material spill from drain cap together, complete GH907 alloy rings punchings.
Compared with prior art, beneficial effects of the present invention are as follows：
The enclosed hole-punching method of GH907 alloys cylinder ring high 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 to rush during punching waiting error partially, improve the consistent of blank
Property.
