Description
Technical field
This utility model is related to a kind of gear cold extrusion die, and in particular to a kind of floating type plug extrusion die of ring gear
Structure.
Background technology
Cold extruding technique is a kind of high-precision, efficient, high quality and low cost vanguard technology technology, and more application is in middle-size and small-size
In forging large-scale production.Compared with conventional contour forging technique, with saving metal material and energy, and forging quality can be improved, improve and make
Industry environment.Ring gear gear is relatively thin due to its wall thickness, if again with traditional mach mode of gear shaping, it is easy to cause internal tooth
The deformation of circle gear, in order to overcome this defect, present ring gear Gear Processing generally to adopt cold extruding technique.Existing cold
In the production technology of extruding ring gear gear, upper mould it is general using using punch and plug as by the way of an entirety, then
When forming to ring gear, plug will produce huge tension and bending stress, be easily caused mandrel fracture, from
And production cannot be normally carried out, and need to re-replace punch, production efficiency is so not only reduced, while having led to producing into
This rising.
Utility model content
For above-mentioned the deficiencies in the prior art, technical problem to be solved in the utility model is：How a kind of adding is provided

Mould includes the die stress seat being arranged on die shoe, and the top of die stress seat is along forming terrace die and female die for forming relative direction
Endoporus is provided through, the die core rod for being coaxial therewith arranging is embedded with endoporus, be embedded with die core rod and be coaxial therewith setting
The bearing ring put and can be slidably matched with it along its axis direction, the length of bearing ring is less than the length of die core rod, pressure-bearing
The plug for being coaxial therewith arranging and can be slidably matched with it along its axis direction, die shoe upper surface correspondence core are provided with ring
The position of rod is arranged with the spring mounting hole extended along plug axis direction, is provided with spring mounting hole as the upper of plug
The spring that bearing ring provides spring force is stretched out at end, and the position of correspondence bearing ring is provided with acting on bearing ring bottom in die shoe
Portion and bearing ring is promoted along bearing ring axis direction, the workpiece at the top of the bearing ring is ejected into the Lifting Device of die core rod,
When upper bolster and die shoe matched moulds, forming terrace die is inserted into carrying out extrusion molding to workpiece in die core rod.
In this utility model, first workpiece blank is held in place on the bearing ring between die core rod and plug, so
Afterwards upper bolster and die shoe carry out matched moulds, and forming terrace die is inserted in die core rod.As forming terrace die is constantly pushed, shaping
The bottom of punch abuts to the top of plug, and its contact surface requires to combine tightly, it is impossible to have gap.Workpiece blank is being extruded
During shaping, while pushing to plug, the spring stress compression below plug, last workpiece blank extrusion molding is completed,
And plug is then formed, punch is depressed in bearing ring.After the completion of extrusion process, upper bolster rises, and forming terrace die leaves die mould
Core, no longer pushes to plug, and spring is in the presence of own spring force by plug jack-up upwards so as to stretch out pressure-bearing in upper end
Ring simultaneously returns to initial position.Last Lifting Device acts on bearing ring bottom, and the workpiece at the top of bearing ring is ejected, and completes to add
Work.During extrusion process is carried out to workpiece, plug can be what is moved up and down, and in addition plug and forming terrace die are again point
Open and be individually present, it is to avoid plug produces larger stress, enters without rupturing, and improves service life, in addition will not
Production is impacted, production efficiency is improve, while reducing production cost.
Used as optimization, the bottom of the spring mounting hole is provided with coaxial with the spring mounting hole and through the die shoe
Lower tension rod thru-hole, a lower pull bar that can be slidably matched with it along its axis direction is equipped with lower tension rod thru-hole, it is drop-down
The screw top of bar is connected to the bottom of plug, and the bottom of lower pull bar arranges restraining position ring block, and spacing ring is to the plug bottom
Apart from length more than the spring mounting hole and lower tension rod thru-hole length sum, the spring is sleeved on drop-down bar.Lower pull bar
Plug can be carried out it is spacing, when forming terrace die to workpiece extruding after the completion of, the contact to plug will be lifted off, plug is just
Can under the action of the spring pop up, axially position be carried out to plug by the spacing ring of lower pull bar bottom, while avoiding core
Rod is ejected from bearing ring.
As optimization, under the Lifting Device includes being arranged on die shoe bottom surface and being connected with the lower tension rod thru-hole
Push rod pilot hole, lower push rod pilot hole is coaxially disposed with the lower tension rod thru-hole, and lower push rod pilot hole holds with diameter greater than described

The bottom of ejector beam is connected to the top of lower push rod, and the length of ejector beam is more than the length of liftout rod through-hole.When workpiece is squeezed into
After the completion of shape, operation lower push rod is moved up, its ejector beam for abutting against of top while also move up along liftout rod through-hole, and
It is connected on bearing ring, also moves up bearing ring, workpiece most at last at the top of bearing ring ejects die core rod, its structure letter
It is single, it is easy to use.
As optimization, the die stress seat include die stress outer ring and be coaxial therewith in die stress outer ring and
The die stress centre circle of interference fit, the die core rod be co-axially located in die stress centre circle and with its interference fit.It is recessed
Mould core rod is directly acted on workpiece during workpiece extrusion molding, and to its material higher, relative price is required
Also it is just higher, in order to reduce its spoilage, need to strengthen die core rod.By in die stress outer ring, die stress
Circle and die core rod interference fit each other, make die core rod be subject to an initial prestressing force, work before workpiece extruding
Service load can offset a part or even whole prestressing force when making.If no prestressing force, the stress that service load is produced
By more than the strength degree of material, die core rod can be by drawing crack.By two stress in die stress outer ring and die stress centre circle
Circle interference fit, reaches enhancement purpose.
In sum, the beneficial effects of the utility model are：This utility model simple structure, using floating type plug
Extrusion die, plug not easy fracture during extruding, improves production efficiency and extends the mold use life-span, reduces and produces into
