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 TC4 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 TC4 alloys of the present invention, its technical scheme
Comprise the following steps：
TC4 alloys are cutting into into bar according to certain specification；TC4 alloy bar materials are heated to 30 DEG C below transformation temperature,
It is incubated by 0.6min/mm；After heat penetration, TC4 alloy bar materials are placed on forcing press, drive forging hammer to carry out upsetting to TC4 alloy bar materials
Slightly to preliminary dimension；TC4 alloy blanks after jumping-up are put in punching die, and is placed on together under forcing press, punching die
Outer wall have for fixed dovetail groove, prevent punching die and TC4 alloy blanks with forging hammer move, limit is placed with punching die
Position disc, the disc is designed according to the height of TC4 alloy blanks, makes TC4 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 TC4 alloy blanks, under driving forging hammer
Pressure drift, drift is pressed in TC4 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 the contact area of blank and drift, and H is
Drift is pressed into the depth of blank；TC4 alloy blanks are taken out and are placed 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 is consistent with the external diameter of TC4 alloy blanks, and TC4 alloy blanks are just placed on spacing
In hole；It is placed on after drift is inverted on the endoporus of TC4 alloy blanks, drives forging hammer to push drift, drift is pressed into into TC4 alloy preforms
In material；Forging hammer is lifted, a cushion block is put on drift, then drive forging hammer to push cushion block, TC4 alloy blanks are washed open, padded
Block, drift and punching core material spill together from drain cap, complete TC4 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 TC4 alloys of the present invention, by designing punching die, it is therefore prevented that blank end
The defects such as material, deformation are drawn in face, and blank need not carry out round as a ball shaping operation, reduce operating procedure and reduce operation difficulty,
Improve 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 uniformity of blank.
Description of the drawings
The present invention is described in further detail with reference to the accompanying drawings and detailed description.
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.
Fig. 5 is the process schematic for being washed open blank using cushion block.
Specific embodiment
Implementing the enclosed hole-punching method of the high cylinder ring of TC4 alloys of the present invention needs to provide forge furnace, pressure
The equipment such as machine, manipulator.Its specific embodiment：
The main chemical elements content (percentage by weight) of the TC4 alloys is：Containing Al amounts 5.5%～6.8%, V content
3.5%～4.5%, containing Fe amount 0.30%, C content 0.10%, leaded wastewater 0.05%, containing H amount 0.015%, containing O amount 0.20%, it is remaining
Measure as Ti.
The step of this method, is as follows：
TC4 alloys are cutting into into bar according to certain specification；TC4 alloy bar materials are heated to 30 DEG C below transformation temperature,
It is incubated by 0.6min/mm；After heat penetration, TC4 alloy bar materials are placed on forcing press, drive forging hammer to carry out upsetting to TC4 alloy bar materials
Slightly to preliminary dimension；TC4 alloy blanks 4 after jumping-up are put in punching die 1, and is placed on together under forcing press, perforating die
The outer wall of tool 1 has for fixed dovetail groove, prevents punching die 1 and TC4 alloy blanks 4 from moving with forging hammer, as shown in figure 1,
