Description
Technical field
The invention belongs to forging equipment field, and in particular to a kind of planet carrier blank forging equipment.
Background technology
Planet carrier blank forging is a common technology in planet carrier process, in order to reach certain characteristic, forging
Part is needed after high temperature forging to obtain this kind of performance.Forge furnace is the indispensable process equipment of forging processing.And show
The heat losses of workpiece are rapid in the forging process of some forge furnaces so that planet carrier slab temperature declines quickly, after forging
Mechanical property do not reach requirement；And punching press head surface is low temperature, can be reduced moment at the surface of pressure head contact workpiece should
Partial temperature, easily there is mechanical performance loss in the surface for the planet carrier blank for causing to be forged, or even slight crack occurs.
The content of the invention
It is an object of the invention to provide a kind of planet carrier blank forging equipment, and planet carrier blank can be kept the temperature, and
And staking punch is heated in advance, when preventing the surface of staking punch contact workpiece moment reduce the temperature of the part.
To reach above-mentioned purpose, base case of the invention is as follows：
Planet carrier blank forging equipment, including incubation cavity, incubation cavity are semicircle, and punching press slide is equipped with the top of incubation cavity,
The side wall both sides of punching press slide are equipped with liquid guiding cavity, and liquid guiding cavity tilts upward, and the input end of liquid guiding cavity is hinged with hollow connecting rod,
Rod surface slidably connects slide plate, and the end of connecting rod, which is fixed, is communicated with oil pocket；Staking punch is slidably connected in punching press slide, is rushed
Pressure head is equipped with hydraulic stem, and hydraulic stem is equipped with strut, and strut is compared with hydraulic pressure shank diameter smaller；Drive link is hinged with strut, is passed
The other end of lever is hinged with slide plate.
The principle of this programme planet carrier blank forging equipment is：
When forging planet carrier blank, incubation cavity is covered on blank first, under the actuating unit for starting the external world at this time
Staking punch is pressed, staking punch moves up and down the link rotatable that can be driven on oil pocket, when staking punch is moved to above liquid guiding cavity,
The position of oil pocket is just slightly above liquid guiding cavity, so the fuel oil in oil pocket can be flowed out to liquid guiding cavity at this time, when punch rod downlink
When, the fuel oil flowed out can be push and moved downward, be closed space below staking punch, pressure can be increasing, this
The temperature of a little fuel oils can be higher and higher, finally burns when staking punch downlink, high temperature caused by burning just can be right
The surface of staking punch is heated, and has achieveed the purpose that to preheat staking punch.Moment reduces when preventing the surface of pressure head contact workpiece
The temperature of the part, avoids causing the surface of planet carrier blank from mechanical performance loss occur.Staking punch downlink to crossing drain
After the distance of chamber one end, the connecting rod slide that can be stamped props up, and can only move on strut and play spacing effect without rotation.
This programme can keep the temperature planet carrier blank, and staking punch is heated in advance, prevent staking punch from contacting
Moment reduces the temperature of the part during surface of workpiece.
Preferred solution one：As the further optimization to base case, the bottom of incubation cavity is equipped with cushion, cushion by
Rubber is made, and avoids damage to incubation cavity.
Preferred solution two：As the further optimization to base case, the sidewall edge of staking punch is equipped with sealant, seals
Layer by polyurethane into；So that airtight performance is more preferable.
Preferred solution three：As the further optimization to base case, the initial position of drive link tilts down, prevents from firing
Oil is toppled over.
Brief description of the drawings
Fig. 1 is the structure diagram of planet carrier blank forging apparatus embodiments of the present invention.
Embodiment
Below by embodiment, the present invention is described in further detail：
Reference numeral in Figure of description includes：Incubation cavity 1, cushion 2, staking punch 3, hydraulic stem 4, strut 5, punching press
Track 6, oil pocket 7, connecting rod 8.
Embodiment is substantially as shown in Figure 1：
The planet carrier blank forging equipment of the present embodiment includes incubation cavity 1, and incubation cavity 1 is semicircle, and the top of incubation cavity 1 is set
There is punching press slide, the side wall both sides of punching press slide are equipped with liquid guiding cavity, and liquid guiding cavity tilts upward, and the input end of liquid guiding cavity is hinged with
Hollow connecting rod 8,8 surface of connecting rod slidably connect slide plate, and the end of connecting rod 8, which is fixed, is communicated with oil pocket 7；Slided in punching press slide
Staking punch 3 is connected with, staking punch 3 is equipped with hydraulic stem 4, and hydraulic stem 4 is equipped with strut 5, and strut 5 is compared with 4 diameter smaller of hydraulic stem；
Drive link is hinged with strut 5, the other end and the slide plate of drive link are hinged.The sidewall edge of staking punch 3 is equipped with sealant, insulation
The bottom of chamber 1 is equipped with cushion 2.
The specific work process of the present embodiment planet carrier blank forging equipment is：
When the present apparatus can forge planet carrier blank, incubation cavity 1 is covered on blank first, starts extraneous move at this time
Force mechanisms push staking punch 3, and staking punch 3, which moves up and down, can drive the connecting rod 8 on oil pocket 7 to rotate, and staking punch 3 is moved to drain
When above chamber, the position of oil pocket 7 is just slightly above liquid guiding cavity, so the fuel oil in oil pocket 7 can be flowed out to liquid guiding cavity at this time,
When punch rod downlink, the fuel oil flowed out can be push and moved downward, the lower section of staking punch 3 is closed space, pressure
Power can be increasing, and the temperature of these fuel oils can be higher and higher, finally burns when 3 downlink of staking punch, and when burning produces
High temperature the surface of staking punch 3 can just be heated, achieveed the purpose that preheat staking punch 3.Prevent pressure head from contacting work
Moment reduces the temperature of the part during surface of part, avoids causing the surface of planet carrier blank from mechanical performance loss occur.Punching press
First 3 downlink to after crossing liquid guiding cavity one end distance, the connecting rod slide that can be stamped props up, can only be moved on strut 5 without
Rotation plays spacing effect.
This programme can keep the temperature planet carrier blank, and staking punch is heated in advance, prevent staking punch from contacting
Moment reduces the temperature of the part during surface of workpiece.
Above-described is only the embodiment of the present invention, and the general knowledge such as known concrete structure and characteristic is not made herein in scheme
Excessive description., without departing from the structure of the invention, can be with it should be pointed out that for those skilled in the art
Several modifications and improvements are made, these should also be considered as protection scope of the present invention, these are implemented all without the influence present invention
Effect and practical applicability.The scope of protection required by this application should be based on the content of the claims, in specification
The records such as embodiment can be used for the content for explaining claim.
