Background technology
Press machine tool is one of important component part of industrial foundation equipment, and department is used widely in Aero-Space, automobile making, communications and transportation, chemical metallurgy etc. essential industry.For an industrially developed country, the technical merit of press machine tool and owning amount are the important symbols of its industrial flourishing level.
Press machine tool needs workpiece is ejected from mould behind the forging and pressing workpiece, and the mechanism that ejects workpiece is material jacking mechanism, and it is fast that mechanical material jacking mechanism has speed, the advantage that efficient is high.Thereby the inventor has designed a kind of cam that adopts in conjunction with the material jacking mechanism of lever, the roof pressure lever motion by the cam running, thereby when cam is rotated the radian of outer change make stroke that cam produces the roof pressure end of lever by lever amplified obtain bigger to the ejector beam ejection stroke, thereby under the constant situation of the rotating speed of power transmission shaft, adopt small-sized its outer of cam can obtain more high linear speed, by lever its stroke is amplified again and guaranteed that the stroke of liftout is constant or higher, thereby the speed of its liftout is faster, and efficient is higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of forcing press cam lever material jacking mechanism.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of forcing press cam lever material jacking mechanism, it is characterized in that: comprise some ejector beams, be hubbed at the power transmission shaft on the frame and be arranged at back shaft on the frame, be installed with some cams on the described power transmission shaft, be pivoted with lever on the described back shaft, be pivoted with first roller on the lever, the outer phase roof pressure of the outer of described cam and first roller, thus make the lever can the roof pressure ejector beam and ejector beam is risen.
The pivoting point of described back shaft and lever is positioned at the end of lever, and the pivoting point of described first roller and lever is positioned at the place, centre position of lever.
Described lever comprises first rod member and second rod member, this first rod member and second rod member all are hubbed on the described back shaft, described first roller is hubbed between first rod member and second rod member by first pivot, and be provided with second roller between first rod member and second rod member, described ejector beam is subjected to the roof pressure of second roller and rises.
Described cam comprises that the first half take turns and the second half wheels, and the first half take turns and are provided with the first semi-ring fixed part, and the second half take turns and are provided with the second semi-ring fixed part, and this cam is fixed by the first semi-ring fixed part and the second semi-ring fixed part locking power transmission shaft.
The described first semi-ring fixed part is connected and the locking power transmission shaft by screw with the second semi-ring fixed part.
The beneficial effects of the utility model are: the roof pressure lever motion by the cam running of this mechanism, thereby the radian variation of outer can make cam that the roof pressure place of lever is produced stroke when cam rotates, and can amplify this stroke by lever, end at lever obtains a bigger ejection stroke, thereby under the constant situation of the rotating speed of power transmission shaft, adopt small-sized its outer of cam just can obtain more high linear speed, by lever its stroke is amplified again and guaranteed that the stroke of liftout is constant or higher, thereby the speed of its liftout is faster, and efficient is higher.
In sum, this mechanism liftout speed is fast, efficient is high, thus be fit at a high speed, the punch press of high-accuracy, high rigidity.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the cutaway view of this structure;
Fig. 2 is the three-dimensional view of this structure.
Fig. 3 is the three-dimensional view of this structure other direction.
The specific embodiment
Referring to figs. 1 through Fig. 3, the utility model discloses a kind of forcing press cam lever material jacking mechanism, comprise ejector beam 1, be hubbed at the power transmission shaft 2 on the frame and be arranged at back shaft 3 on the frame, be installed with cam 4 on the described power transmission shaft 2, be pivoted with lever 5 on the described back shaft 3, be pivoted with first roller 6 on the lever 5, the outer phase roof pressure of the outer of described cam 4 and first roller 6, thereby make the lever 5 can roof pressure ejector beam 1 and ejector beam 1 is risen, in this example, power transmission shaft 2 is shared power with the bent axle of forcing press, thereby more energy-conservation, ejector beam 1 is arranged in the frame by linear bearing, and can pass the punching press platform of compacting workpiece, guaranteed ejector beam 1 motion smoothly, and loss is little.
As shown in the figure, the pivoting point of back shaft 3 and lever 5 is positioned at the end of lever 5, the pivoting point of described first roller 6 and lever 5 is positioned at the place, centre position of lever 5, that the stroke that guarantees lever 5 roof pressure ejector beams 1 is set is enough by above-mentioned, can make the point of application of 4 pairs of levers 5 of cam enough with the length of the pivoting point of lever 5 to back shaft 3 again, thus more laborsaving.
As shown in the figure, lever 5 comprises first rod member and second rod member, this first rod member and second rod member all are hubbed on the described back shaft 3, described first roller 6 is hubbed between first rod member and second rod member by first pivot, and be provided with second roller 7 between first rod member and second rod member, described ejector beam 1 is subjected to the roof pressure of second roller 7 and rises, by above-mentioned setting, both guaranteed that first roller 6 and cam 4 and second roller 7 were rolling friction with ejector beam 1, thereby it is little to wear and tear, have and to guarantee that lever 5 has enough rigidity, can bear bigger power.
As shown in the figure, cam 4 comprises that the first half take turns 8 and the second half and take turns 9, the first half take turns 8 is provided with the first semi-ring fixed part 10, the second half take turns 9 is provided with the second semi-ring fixed part 11, and this cam 4 is fixed by the first semi-ring fixed part 10 and the second semi-ring fixed part, 11 locking power transmission shafts 2, the first semi-ring fixed part 10 is connected and locking power transmission shaft 2 by screw with the second semi-ring fixed part 11, pass through said structure, cam 4 can be easily installed on the power transmission shaft 2 and dismounting, and what is more important, pass through said structure, the relative position that each cam is 4 can freely be set adjusting, because, workpiece itself may be have a concaveconvex shape or be placed with a plurality of workpiece at the punching press platform, differ in the roof pressure position of every ejector beam 1 roof pressure workpiece, thereby ejector beam 1 moves to the stroke at the roof pressure place of workpiece also inequality, but in order to guarantee the stressed even of workpiece, just need the ejector beam 1 of the same workpiece of roof pressure to force in simultaneously on this workpiece, just must realize by the relative position of adjusting 4 on each cam, when initial position, the convex arc setting of each cam 4 is positioned at different positions, need long stroke could with the workpiece contact ejector beam 1 can contact with the convex arc of corresponding cam 4 is first, need short stroke could with workpiece contact ejector beam 1 can with the convex arc of corresponding cam 4 after contact, thereby after power transmission shaft 2 turned an angle, all ejector beams 1 can simultaneously contact the application of force with surface of the work and the roof pressure workpiece ejects workpiece from mould.
Above-mentionedly just preferred embodiments more of the present utility model are illustrated and describe; but embodiment of the present utility model is not restricted to the described embodiments; as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
