Description
Technical field
The present invention relates to forging mold technical fields, are specifically related to a kind of multi-stage gear combined type finish forge mould.
Background technology
Gear is the core transmission component in motor racing, and the quality of processing quality shakes to automobile assembly or even vehicle
Moving noise and reliability etc. can bring and directly affect, and become the key factor that limit product level improves sometimes.Existing skill
The forging mold of multi-stage gear in use, will produce overlap on the part of forging in art；Often lacking there is also quality
It falls into, the blank of workpiece needs complicated machine cut processing, workload to increase, and has many chipping allowances, waste of material amount
Greatly, cost increases；In addition forging pressure generates powerful stress impact to mold and is inevitable, and mold is in strong stress
Under be deformed, influence the structure of mold and precision also affect the service life of die life, brought centainly to user
Economic loss.
Invention content
The purpose of the present invention is：Raising forging is realized for insufficient a kind of finish forge mould structure of offer in the prior art
Quality, reduce machining amount with reduce material waste and workload, solve flashing problems, reduce mold stresses deformation,
Improve die life.
In order to achieve the above object, the present invention uses following technical scheme：
A kind of multi-stage gear combined type finish forge mould, including upper mold, lower pre- mould, lower whole mould, lower mould bottom plate, guide-rail plate, rack-plate,
Analyzing rod, movable plate, actuating mechanism, gear, rack ejector beam, pull plate；The upper mold setting is fluted, and upper mold passes through measurement
The position of whole mould, the lower pre- mould are provided with taper hole under bar is oriented to the position of pre- mould under restriction and limits, and taper hole is tapered,
Upper section, which accumulates, is more than lower section product, is provided with endoporus in the lower whole mould, hole size is forging products size, and lower pre- mould is under
Whole mould is fixed in lower mould bottom plate, all excavation has movable plate, the movable plate and corresponding lower die in bearing's lower mould bottom plate
Gas vent is all offered on bottom plate, the lower mould bottom plate is engaged on guide-rail plate, and one end is fixed with actuating mechanism, by acting machine
The drive of structure can horizontally slip, and described guide-rail plate one end is provided with liftout mouth, and rack ejector beam is provided below, and the rack-plate is embedding
It falls on guide-rail plate, rack-plate is engaged with gear down, and gear side is engaged with rack ejector beam, and described pull is arranged on plate
There is sliding elongated slot and mutually fixed with one side of rack-plate, pull plate one is also fixed on guide-rail plate, is branch with this fixed point
Point, which can push and pull, to be pulled plate rack-plate is driven to move left and right, and motion track is parallel with the sliding trace of lower mould bottom plate, when pulling plate
When pulling rack-plate to move to right to the right, rack-plate then turn right by band moving gear, and band carry-over bar ejector beam moves up ejection forging to gear again.
Job order of the present invention is：Actuating mechanism movement lower mould bottom plate makes lower pre- mould under upper mold, is led by analyzing rod
To, and limit progress pre-forging after accurate location is measured, stress deformation caused by forging and stamping is alleviated since lower pre- mould is tapered, separately
Outside since upper mold is arranged fluted, excess stock overflows, and is not required to trimming, is moved in upper mold after the completion of pre-forging under analyzing rod is detached from
Pre- mould, then actuating mechanism push lower mould bottom plate to lower pre- mould above liftout mouth, then easily pull hand using lever principle
Pulling plate moves right to drive rack-plate to move right, and rack-plate band moving gear is turned right, and is pushed up on gear band carry-over bar ejector beam
Movable plate ejects pre- forging, pre- forging is put into the endoporus of lower whole mould, recycles lever principle easily to pull and pulls plate to moving to left
It moves that rack-plate is driven to be moved to the left return, rack-plate band moving gear turns left, and gear band carry-over bar ejector beam moves down return.So
Actuating mechanism movement lower mould bottom plate makes lower whole mould under upper mold afterwards, is oriented to by analyzing rod, and limited after measuring accurate location
Finish-forging is carried out, due to there is blocking, finish-forging forging amount is small, and pre- forging is tapered, and it is high that finish-forging deforms small quality, equal to having modified
Size, forging dimensional accuracy height need not be machined out again, time saving and energy saving, saved material.After the completion of finish-forging, upper mold moves up
It is detached from lower whole mould to analyzing rod, then actuating mechanism pushes lower mould bottom plate above liftout mouth, then to recycle thick stick to lower whole mould
The light pulling of rod principle pulls plate and moves right to drive rack-plate to move right, and rack-plate band moving gear is turned right, gear band
On carry-over bar ejector beam push up movable plate eject finish-forging part, finally recycle lever principle easily pull pull plate be moved to the left to
Rack-plate is driven to be moved to the left return, rack-plate band moving gear turns left, and gear band carry-over bar ejector beam moves down return, prepares forging
Next forging.It is fixed simultaneously with rack-plate and guide-rail plate due to pulling plate, and, as fulcrum, to be utilized with guide-rail plate bearing
Lever principle can it is easy, easily effortlessly pull and pull plate, and the containing of rack-plate and guide-rail plate to pull when pulling plate,
Rack-plate can not possibly be detached from guide-rail plate, and to ensure that engaging for rack-plate and gear, making rack-plate, reliably band moving gear rotates.
In addition use actuating mechanism, lower mould bottom plate and guide-rail plate be engaged sliding equipment, play leverage pull plate and rack-plate
And the combination of the drive mechanism of gear, keep the installing, move of forging mold, depanning convenient and efficient time saving and energy saving, efficient；Lower die
The occlusion of bottom plate and guide-rail plate is arranged, that is, has played guiding movement, and makes the pressing mold effect for having downward when depanning liftout, saves
The fixing devices such as bolt cause the replacement, easy for installation, quick of mold.The arrangement of guide-rail plate can fix lower mould bottom plate and
Rack-plate has played buffer board again, and impact of the mold to forging and stamping machine worktable, has extended forging press when reducing forging and stamping
Service life avoid high pressure air mass to influence metal flow and mold damage additionally, due to gas vent has been opened up, extend mold
Service life.
As preferred：
Further, the taper a of the taper hole is：0°≤a≤5°.
Further, the analyzing rod setting quantity is 1-3.
Further, the actuating mechanism uses electric pushrod.
Further, the actuating mechanism uses hydraulic mechanism.
Further, the actuating mechanism uses pneumatic mechanism.
Further, the movable plate is tapered, and upper section product is more than lower section and accumulates.
Further, the guide-rail plate is provided with travel switch, and 2-4 block limited blocks are provided in the lower mould bottom plate.
Further, the limited block is rotatable.
Using the advantageous effect after above-mentioned technical proposal:
1, using becoming smaller to the impact stress of mold after lower pre- mould, lower whole die combination forging, to which die deformation is small, in conjunction with taper hole
On taper, make that forging precision is high, quality is good, eliminate machining operation, time saving, laborsaving, material saving, and improve mold
The service life in service life.
2, fluted using upper mold setting, excess stock overflows, and trimming is not required to, without flashing problems.
