Description
Technical field：
The utility model is related to forging machine tool technical fields, and in particular to a kind of lower forging of forging machinery forcing press machinery squeeze and
Lifting Device.
Background technology：
Bottom ejection device is one of mechanical press critical piece.At present, forging press bottom ejection device is big in the market
In addition mostly cam-type also has a small number of pneumatic types.Above two bottom ejection device be mainly used for forging machinery forcing press forging and
The ejection of part after forging has the characteristics that high protect ejects, convenient for holding parts and automated production, and These characteristics become forging
The major function requirement of mechanical press.
But nowadays, manufacturing industry is grown rapidly, Market competition, and manufacturing enterprise proposes purchased equipment higher will
Ask ----meet crowded forging, stretching and ejection complicated procedures of forming, reduce energy consumption, improve mechanical efficiency, green production.It is existing both
All there are certain defects for bottom ejection device, it is impossible to meet the needs of manufacturing enterprise well.As shown in Figs. 1-2, pushed up under cam-type
Material device is by the rotary force of bent axle, and torque is converted into the swing of swing rod to drive pull rod up and down motion by cam mechanism
Power, then the power that pull rod moves up and down is converted by the torque that axis swings by connecting rod, it is swung finally by bottom knockout axis by torque
The upward liftout power of ejector beam is then converted to, the ejection of forging parts is realized in (eccentric wheel hysteresis drift angle) asynchronous with sliding block action,
After the completion of the action of mechanical liftout, assistant cylinder starts to start, and cylinder piston rod is connected on connecting rod, passes through connecting rod, bottom knockout
Axis, using the action identical with mechanical liftout, continues upwards to eject ejector beam, and forging is ejected and in lower mode cavity in highest
Position is kept for a period of time and (is convenient for clamping forge piece), so far, completes entire liftout process.Said mechanism is to the conversion number mistake of power
More (up to 3 times), energy loss is big, and structure is more complicated, manufacture is of high cost；And cam-type machinery bottom ejection device also has the liftout complete

The problems such as high, adds production cost, reduces production efficiency, does not meet current manufacturing enterprise and green energy conservation production is wanted
It asks.Most importantly forging (multistation) mechanical press needs the lower forging more than nominal pressure more than 30% to squeeze or extension force requirements
When carrying out bottom knockout again afterwards, cam-type machinery bottom ejection device can not just be realized；And cam-type machinery bottom ejection device can not
The ejecting force of mechanical liftout is adjusted, overload is be easy to cause, lathe and forging is damaged.
As shown in figure 3, pneumatic type bottom ejection device is that cylinder is suspended on pedestal in the following, piston rod and the direct phase of ejector beam
Even, by the movement of cylinder, direct liftout, the mechanism structure is simple, reliable operation, but ejecting force is smaller, is only used for part punching
Part is ejected out of mold after pressure, it is impossible to meet forging and squeeze job requirement.At present only to of less demanding a small amount of small of liftout power
It is used on type mechanical press.

Eccentric bushing 20 is mounted on by synchronous keyway 44 on bent axle 1, the bias and bent axle 1 of eccentric bushing 20 are eccentric in the same direction,
When bent axle 1, which rotates band movable slider 47, to be moved downward, bent axle 1 drives connecting rod 18 to move also by eccentric bushing 20, and connecting rod 18 drives
Upper connecting rod 2 and lower pull rod 5 move downward, and lower pull rod 5 promotes lever 7 to move, and lever 7 jacks up liftout seat 15, and liftout seat 15 is again
Top plate 13 and upper ejector pin 12 are jacked up, sliding block 47 acts on forging simultaneously with upper ejector pin 12, when pull rod power is more than disk spring 28
After pretightning force, disk spring 28 starts to be compressed, and the pressure and stroke squeezed or stretched until reaching forging realize what forging was squeezed or stretched
Process；After the completion of forging is squeezed or is stretched, the rotation of bent axle 1 band movable slider 47 and 18 upward return of connecting rod move, due on sliding block 47
Shifting, 28 compressive of disk spring, stroke quick release promote 7 left end of lever to continue to move downward, and 7 right end of lever continues up
Movement, and then the forging after having forged crowded or stretching is ejected the height of setting by drive liftout seat 15, upper ejector pin 12 from mold 42,
At this moment the startup of cylinder 14 overcomes the power that top plate 13 moves downward, and piston rod ejects upwards, make top plate 13 and upper ejector pin 12 continue to
