Abstract
The utility model discloses a cam liftout mechanism, the utility model discloses a transmission shaft in the frame is located to a plurality of liftout poles, pivots, fixed mounting has a plurality of cams on the transmission shaft, the outer edge of cam and liftout pole looks roof pressure to make the liftout pole rise, through the motion of cam operation roof pressure liftout pole, the radian change on outer edge when rotating through the cam makes the liftout pole produce the lift stroke, because of the cam rotational speed is high, the rigidity is good, therefore the fast of its liftout, efficient, simple structure easy to maintain moreover.
Description
Technical field
The utility model relates to a kind of forcing press, particularly a kind of cam material jacking mechanism.
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 material jacking mechanism that adopts the cam liftout, the roof pressure ejector beam motion by the cam running, the variation of the radian of outer makes ejector beam produce lifting travel when rotating by cam, because of cam rotating speed height, good rigidly, thereby the speed of its liftout is fast, the efficient height.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of cam material jacking mechanism.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of cam material jacking mechanism is characterized in that: comprises some ejector beams, is hubbed at the power transmission shaft on the frame, be installed with some cams on the described power transmission shaft, and the outer of described cam and ejector beam phase roof pressure, thus ejector beam is risen.
Described ejector beam guides and lifting by the linear bearing that is arranged in the frame.
The end of described ejector beam is provided with contiguous block, and contiguous block is provided with holding tank, is provided with the roller, described cam and the roller roof pressure that articulate with contiguous block in the holding tank.
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 utility model comprises some ejector beams, is hubbed at the power transmission shaft on the frame, be installed with some cams on the described power transmission shaft, the outer of described cam and ejector beam phase roof pressure, thereby ejector beam is risen, the roof pressure ejector beam motion by the cam running, the variation of the radian of outer makes ejector beam produce lifting travel when rotating by cam, because of cam rotating speed height, good rigidly, thereby the speed of its liftout is fast, the efficient height, and also simple in structure being easy to safeguarded.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is three-dimensional view of the present utility model;
Fig. 2 is cutaway view of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, the utility model discloses a kind of cam material jacking mechanism, comprise some ejector beams 1, be hubbed at the power transmission shaft 2 on the frame, be installed with some cams 4 on the described power transmission shaft 2, the outer of described cam 4 and ejector beam phase roof pressure, thus ejector beam 1 is risen.
In order to guarantee that ejector beam 1 can run-off the straight and skew in lifting, and it is minimum that wearing and tearing are wanted, and ejector beam guides and lifting by the linear bearing that is arranged in the frame, and can pass the punching press platform 10 of compacting workpiece, guaranteed ejector beam 1 motion smoothly, and loss is little.
In order to reduce the wearing and tearing of cam 4 and ejector beam 1, the end of ejector beam 1 is provided with contiguous block 3, and contiguous block 3 is provided with holding tank, is provided with the roller 5 that articulates with contiguous block 3 in the holding tank, described cam and roller 5 roof pressures, and roller 5 can adopt bearing certainly.
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 6, the second half take turns 9 is provided with the second semi-ring fixed part 7, and this cam 4 is fixed by the first semi-ring fixed part 6 and the second semi-ring fixed part, 7 locking power transmission shafts 2, the first semi-ring fixed part 6 is connected and locking power transmission shaft 2 by screw with the second semi-ring fixed part 7, 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.
