Description

The liftout attachment that is used for building mortion
The present invention relates to a kind of liftout attachment that especially can be used in the forcing press.
Especially in solid shaping, other forming process and original formation process, the workpiece that must after forming process, will form in the mould breaks away from the mould of opening.Need use liftout attachment for this reason.If the shaping dies of horizontal parting, then these liftout attachment majorities are arranged in the mould bottom.Comprise at least one knock-pin, this knock-pin is in resting position in forming process.After forming process finishes and opens mould, make knock-pin vertically (for example vertical) move, thereby make workpiece break away from mould, and be placed on and transmit height.
DE 40 17 796C1 just disclose a kind of liftout attachment that is used for injection (mo(u)lding) machine.This liftout attachment comprises the driving mechanism that ejects of a hydraulic cylinder pattern.The piston rod of its piston drives an adjustable liftout plate that is installed on the knock-pin.Knock-pin is outwards extruded workpiece from mould when hydraulic cylinder starts.
Workpiece in solid forming process, can occur and after forming process finishes, anchor at the problem in the mould.It is got loose from force-fitted state.Need very big power for this reason.To overcome very big difference in height in addition, could workpiece be placed and transmit height.Like this one side need design size very big eject driving mechanism.
Workpiece being got loose and eject the required time also can restriction pressure machine number of strokes may.Therefore liftout attachment should be with fast as far as possible speed operation.The very big power requirement of this requirement and the above liftout attachment is just in time runed counter to.
Therefore task of the present invention is, sets forth a kind of very liftout attachment design of high pressure machine number of strokes may that can be used to realize.
Adopt the described liftout attachment of claim 1, can solve this task:
Liftout attachment of the present invention is applicable to shaping dies, is particularly useful for class-consicous dies, is particularly useful for solid shaping, also is applicable to casting or diel.
Liftout attachment of the present invention has a knock-pin, and its drive unit comprises first drive unit and second drive unit.First and second drive units can be carried out various tasks.The driving stroke of first drive unit is less than the impulse stroke of knock-pin.First drive unit can provide extra high driving force.Therefore can it be used for making that workpiece gets loose from mould.Second drive unit especially has very high actuating speed.Can when workpiece gets loose, drive knock-pin, make workpiece with very high speed get into clamping or conveyer can with its catch and the position of continuing to carry among.
Therefore first drive unit also can regard it as " power set " owing to have very big driving force.The impulse stroke of enough is first drive unit has several millimeters for example 20mm.The speed that first drive unit is realized can be smaller.First drive unit can comprise a driver and the transmission mechanism that speed reducing ratio is bigger.Transmission mechanism can be a kind of mechanical transmission mechanism, hydraulic gear or the like.
Second drive unit is used to overcome the major part stroke of knock-pin.It not only can reach for example 8m/s or higher maximal rate, can also preferably under the situation of Stroke Control, work in addition.For example second drive unit can comprise the driving mechanism of a servomotor or similar Position Control formula work.So just can make knock-pin with required displacement time curve motion, thereby can quicken workpiece, follow the tracks of the mould of opening and make its controlled entering inactive state in the desired position.Workpiece can be in this way controllably, but still shift out with very high speed.The work of second especially can the stroke controlled drive unit is skidded workpiece or is taken off and can't be transmitted the danger that device correctly takes away by the top and is reduced to minimum level on knock-pin.
Aptly an adjusting device that can be used to adjust the knock-pin resting position is attached troops to a unit among knock-pin.This seems useful especially especially among liftout attachment is incorporated into the pressure board that lower mold portion is installed the time.If in mould or forcing press, adopt for example corresponding to a plurality of liftout attachments not at the same level of class-consicous dies in addition, then adjusting device is favourable.Can suitably adjust the position of knock-pin, make it to adapt to the workpiece shape that changes with level.
Advantageously, first drive unit has an adjustable output element that can utilize adjusting device to adjust towards drive unit.For example can output element be linked to each other with first drive unit through screw thread.Rotate output element through adjusting device, can adjust the resting position of first drive unit.
Said according to a kind of first-selected embodiment, knock-pin links to each other with first drive unit through contact-making surface.This contact-making surface plays the effect of pressure face.Such first drive unit just can push knock-pin towards workpiece.But also can be so that knock-pin easily leaves first drive unit.Can use for example second drive unit for this reason.
Second drive unit can drive knock-pin in the position of regulation.But also can not only start first drive unit; And can start second drive unit; In case the first bigger drive unit of strength makes workpiece and mold separation thereby speed is slow, but then second drive unit of the more weak rapid speed of strength will drive knock-pin.
Can realize the present invention with different embodiment.For example first drive unit can be a kind of fluid pressure drive device.First drive unit also can comprise preferred reduction gearing mechanism, for example a lever transmission mechanism.If use the toggle link transmission mechanism as transmission mechanism, just can realize extra high breakaway force with very little cost.When first drive unit is in resting position,, then especially true if the toggle link transmission mechanism is in expanded position.
Second drive unit can be the linear electric motors direct drive unit of for example knock-pin, or for example connects through the pinion tooth bar or similar transmission mechanism links to each other with knock-pin other driven by servomotor device.Second drive unit can comprise one or more motors.

Accompanying drawing 1 is depicted as forcing press 1 sketch map that class-consicous dies 2 have been installed.Class-consicous dies 2 comprise a upper mold portion 3 and a lower mold portion 4, by the push rod support upper mold portion 3 of a corresponding guiding that in hydropress frame 5, vertically moves up and down.Lower mold portion 4 is placed on the pressure board 7.Upper mold portion 3 is being confirmed at least one each other with lower mold portion 4, if class-consicous dies then have a plurality of corresponding die cavitys 8,9,10,11,12 that are in the punch 13,14,15,16,17 on the upper mold portion 3 that have.One of punch 13 (14~17) the formation class-consicous dies 2 of each die cavity 8 (9~12) and correspondence becomes form class.Through do not draw in detail among the figure, affact mould portion 3 when the moulds open, conveyer between 4 continues conveying workpieces in mould level ground one by one.
Accompanying drawing 2 is depicted as the principle schematic of lower mold portion 3 first order.As shown in the figure have a workpiece 18 of having accomplished shaping in die cavity 8.This workpiece fills up die cavity 8 basically.
Accompanying drawing 2 has also been drawn a liftout attachment 19 that belongs to forcing press 1 or mould 2, and it comprises that a knock-pin 20 and one eject driving mechanism 21, can be arranged among the mould portion 4 perhaps as shown in the figure being arranged among the pressure board 7 with ejecting driving mechanism.Knock-pin 20 is arranged among the opening that leads to die cavity 8 bottoms.Knock-pin can be at this vertical direction straight line move consistent with push rod 6 directions of motion.Eject driving mechanism 21 and be used for suitably handling knock-pin 20, make knock-pin 20 unclamp the workpiece 18 in the die cavity 8, and workpiece is lifted from die cavity, until the upper surface of crossing lower mold portion 4 22.
Eject driving mechanism 21 and comprise a depression bar 23, as shown in the figure, its end face can be attached on the lower end of knock-pin 20.Also can bar 23 and knock-pin 20 be designed to the whole mechanical part that links to each other in addition.Eject driving mechanism 21 can be used to vertically adjust targetedly depression bar 23 come with it the adjustment knock-pin 30.Eject driving mechanism 21 for this reason and comprise two for example drive units shown in the accompanying drawing 3.First drive unit 24 can be used to produce the short stroke motion, in its scope, can use bigger power to drive knock-pin 20 or depression bar 23.First drive unit 24 suits to comprise at least one output element with contact-making surface 26 25 that the end face 27 of depression bar 23 is positioned on this contact-making surface, can it be interpreted as the part of knock-pin 20.
First drive unit 24 also can comprise for example rotor 28, and this rotor has a screwed hole of centre, and the external screw thread 29 of output element 25 can screw among this screwed hole.Output element 25 cannot rotate through the mechanism that is not shown specifically, but can be in the vertically supporting of push rod 23 with adjusting, and rotor 28 still can support for example through thrust bearing 30 axial restraints rotatably.
Rotor 28 can have some permanent magnets 31 on its excircle.The stator 32 that surrounds rotor 28 and fixed-site with one heart constitutes a motor, especially a synchronous motor with permanent magnet 31.Suitably it is triggered, just can move output element with bigger power through stroke H1, the trip is less than the stroke of desired depression bar 23.
Push rod 23 also links to each other with second drive unit 33 in addition, and this drive unit can be used to drive rod 23 on prescribed stroke H.For stroke H is described, in accompanying drawing 3, be in resting position with solid line indication rod 23, be represented by dotted lines to be in and eject the position.
Second drive unit 33 comprises a for example synchronous motor 34 of driving pinion 35.Toothed region 36 engagements on pinion 35 and bar 23 sides that can constitute tooth bar.
The said working method that ejects driving mechanism 21 is following:
Accomplish after the stroke of a press, push rod 6 at first moves upward, thereby makes upper mold portion 3 leave lower mold portion 4, just mould 2 is opened.At this moment situation is shown in accompanying drawing 2.Workpiece 18 after the shaping anchors on die cavity 8 bottoms.Must make it break away from die cavity 8, and it caught, and give for example next forcing press level with it and proceed processing by the conveyer of not drawing among the figure.
Start liftout attachment so that the workpiece on the die cavity 8 18 breaks away from.At least start first drive unit 24 for this reason, but also can start the synchronous motor 34 of second drive unit 33 in case of necessity.For example can make output element 25 move up through first drive unit 24 that rotatablely moves of rotor 28 now with lower speed.Output element 25, makes workpiece leave its set position, thereby it is almost got loose towards workpiece 18 extruding depression bars 23 or 20 with suitable power.Tens tons to 100 tons of required for this reason Li Keda.
In case workpiece 18 breaks away from the set position, second drive unit 33 will continue to lift workpiece 18.Synchronous motor 34 makes bar 23 quicken to move for this reason, and makes workpiece 18 can reach the peak velocity of several meters of per seconds (for example 8m/s) through bar.Only 24 of first drive units of short stroke work can movement therewith.The end face 27 of bar 23 lifts from pressure face 26.Bar 23 passes through stroke H at a terrific speed, makes workpiece 18 be in end face 22 tops.
Conveyer can be taken over workpiece in this position, then it is sent to next press stations or another machining location.
First drive unit 24 at first applies higher power, carriage release lever 23 under the control of the control device that second drive unit 33 is not then drawn in the drawings in detail, and utilize bar to make workpiece 18 under the situation of location-controlled, move at a relatively high speed.Said control device sets required curve movement can for synchronous motor 34; Thereby the upper mold portion that makes workpiece for example follow to open 3 motions; Perhaps even the state that sticks together with its maintenance, can take over the stop position of the hope of workpiece 18 until arriving conveyer.
Can change liftout attachment 21 in a different manner observing under the prerequisite of basic principle.For example can be so that second drive unit 33 outwards moves near the of bar 23.Shown in accompanying drawing 4, the second drive unit 33a is arranged in push rod 23 next doors and its at intervals.Drive tooth bar 37 at this synchronous motor 34a, tooth bar acts on the lower surface 27 of bar 23 through angular lever 38.If suitably design the active force of accompanying drawing 4 shown devices, then also can it be used for substituting first drive unit 24.
Accompanying drawing 5 is depicted as another kind of embodiment, and push rod 23 is here by push rod 23b here, and double rack constitutes, and has two toothed region 36a, 36b for this reason.These toothed region are arranged on the not ipsilateral of bar 23b, and mesh with synchronous motor 34a, the pinion 35a of 34b driving, 35b respectively.Synchronous motor 34a, 34b and its pinion 35a, 35b and tooth bar 23b constitute the second drive unit 33b.The first drive unit 24b comprises a synchronous motor 39 as power source, and an eccentric wheel 40 is arranged on the output shaft of synchronous motor.This eccentric wheel links to each other with toggle link transmission mechanism 42 through connecting rod 41.The first elbow arm 43 of toggle link transmission mechanism is hinged with the bearing 44 of fixed-site.The second elbow arm 45 acts on the latter end 46 of lever 47, and another of lever terminal 48 can swingingly support.In the present embodiment, terminal 48 for example be supported on the adjusting device 49 that constitutes by adjustment eccentric wheel 50.Adjusting device through not drawing in detail among the figure is adjusted it in different position of rotation targetedly, to adjust the height of end 48.
Side at lever 47 constitutes contact-making surface 26, and the end face 27 of tooth bar 23b is positioned on this contact-making surface.
Accompanying drawing 5 is depicted as the resting position that ejects driving mechanism 21b.In this resting position, toggle link transmission mechanism 21 is in expanded position, and just elbow arm 43,45 forms straight line.Connecting rod 41 acts on the pin joint 51.When starting synchronous motor 39, get final product drive link 41 and utilize its to drive pin joint 51 towards a lateral movement.Will make that like this bearing length of toggle link transmission mechanism 42 shortens, thereby make lever 47 upwards swing (counterclockwise) shown in accompanying drawing 5.Therefore from the visual angle of synchronous motor 39, tooth bar 23b will break away from resting position with speed reducing ratio infinitely great, that reduce gradually thereafter originally.So just can great breakaway force be passed to workpiece through leverage shown in the drawings and tooth bar 23b.In case workpiece gets loose, synchronous motor 34a, 34b will quicken, and make workpiece break away from mould with higher speed.
Accompanying drawing 6 is depicted as a kind of embodiment through changing, and wherein the first drive unit 24c is according to hydraulic principle work.It comprises an annular piston 52 that is arranged in hydraulic cylinder 53, and annular piston 52 is cut apart one at least, preferably cut apart two working chambers 54,55.These working chambers all link to each other with hydraulic control device 56.Annular piston 52 has for example female through hole, and output element 25 is positioned among this through hole.It is rotated towards not rotatable annular piston 52 targetedly.Can adopt an actuating motor 57, but this actuating motor links to each other with output element 25 with axially lax not rotatable mode through sliding axle 58 for this reason.Make output element 25 rotate, just can adjust the resting position of pressure face 26 and bar 23 with respect to annular piston 52.Therefore the external screw thread 29 of output element 25 constitutes adjusting devices 49 with sliding axle 58 and actuating motor 57 jointly, also can alternatively use actuating motor to make annular piston 52 rotate towards output element 25.
Can bar 23 also be designed to the tooth bar form.Accompanying drawing 3 is described the same with combining, pinion 35 engagements of the tooth 36 of tooth bar and a suitable drive mechanism (for example synchronous motor).
Liftout attachment 21c shown in the accompanying drawing 6 works in such a way:
Accompanying drawing 6 is depicted as inactive state.Annular piston 52 is in lower position.The lower surface 27 of bar 23 is positioned on the contact-making surface 26, and corresponding triggering actuating motor 57 gets final product the height of adjusting lever 23 with respect to its resting position.
If make workpiece break away from its mould, just must it be got loose now.Can the reversal valve that belong to control device 56 59 be turned to conducting (lower flow channel 60) for this reason, make that working chamber 55 links to each other with the hydraulic pressure that hydraulic pump 61 produces down.The then pressure release of last working chamber 54.Can whole power that annular piston 52 produces be passed to workpiece through bar 23 now, thereby it is got loose.But as shown in the figure, can only accomplish very short stroke.In case workpiece gets loose, the servomotor of driving pinion 35 will drive rod 23 therefore it lifts and moves upward from output element 25.
After taking out workpiece, let servomotor reverse, just can make that bar 23 moves downward again, also can reversal valve 59 be transformed into its reverse position (runner 62), thereby make annular piston 52 come back to the position shown in the accompanying drawing 6.
According to the embodiment shown in the accompanying drawing 3, first drive unit 24 can play the effect of adjusting device 49 simultaneously.Can put the resting position of confirming output element through the rotor 32 and the cyclostasis of the motor of magnet 31 formations.The control device of for example only representing with sketch map in the accompanying drawing 3 63 can be confirmed this resting position through software, and this control device can trigger first drive unit 34 on the one hand, then constitutes adjusting device 49 on the other hand.
Provide a kind of and be particularly useful for forcing press and diel but also can be used for the liftout attachment of other suitable applicable cases, said liftout attachment comprises two drive units 24,33.These two drive units have different strokes, implementation capacity and execution speed.First drive unit makes workpiece get loose, and second drive unit then is used for controlling workpiece and makes it break away from mould with higher speed.
