Abstract
The invention discloses a cam ejection mechanism, which comprises a plurality of ejection rods and a transmission shaft pivoted on a rack, wherein a plurality of cams are fixedly arranged on the transmission shaft, the outer edges of the cams are pressed against the ejection rods, so that the ejection rods are lifted, the ejection rods are pressed by the operation of the cams to move, the ejection rods generate lifting strokes by the radian change of the outer edges when the cams rotate, and the cams have high rotation speed and good rigidity, so that the ejection speed is high, the efficiency is high, the structure is simple and the maintenance is easy.
Description
Technical field
The present invention 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 in Aero-Space, automobile making, communications and transportation, chemical metallurgy etc. essential industry, department is used widely.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 by workpiece from mold ejection after forging and stamping workpiece, and the mechanism ejecting workpiece is material jacking mechanism, and it is fast that mechanical material jacking mechanism has speed, the advantage that efficiency is high.Thus the present inventor devises a kind of material jacking mechanism adopting cam liftout, operated by cam and push up the motion of pressure ejector beam, when being rotated by cam, the radian change of outer makes ejector beam produce lifting travel, because cam rotating speed is high, good rigidly, thus the speed of its liftout is fast, and efficiency is high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of cam material jacking mechanism.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of cam material jacking mechanism, is characterized in that: comprise some ejector beams, the power transmission shaft be hubbed in frame, and described power transmission shaft is installed with some cams, and pressure is pushed up mutually with ejector beam in the outer of described cam, thus makes ejector beam increase.
Described ejector beam is guided by the linear bearing be arranged in frame and is elevated.
The end of described ejector beam is provided with contiguous block, and contiguous block is provided with holding tank, is provided with the roller with contiguous block pivot joint in holding tank, and described cam and roller top are pressed.
Described cam comprises the first half takes 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.
Described first semi-ring fixed part and the second semi-ring fixed part are connected by screw and locking power transmission shaft.
The invention has the beneficial effects as follows: the present invention includes some ejector beams, the power transmission shaft be hubbed in frame, described power transmission shaft is installed with some cams, pressure is pushed up mutually with ejector beam in the outer of described cam, thus make ejector beam increase, operated by cam and push up the motion of pressure ejector beam, when being rotated by cam, the radian change of outer makes ejector beam produce lifting travel, because cam rotating speed is high, good rigidly, thus the speed of its liftout is fast, and efficiency is high, and structure is simply easy to safeguard.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is three-dimensional view of the present invention;
Fig. 2 is sectional view of the present invention.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the invention discloses a kind of cam material jacking mechanism, comprise some ejector beams 1, the power transmission shaft 2 be hubbed in frame, described power transmission shaft 2 is installed with some cams 4, pressure is pushed up mutually with ejector beam in the outer of described cam 4, thus makes ejector beam 1 increase.
In order to ensure that ejector beam 1 can not run-off the straight and skew when lifting, and it is minimum to wear and tear, ejector beam is guided by the linear bearing be arranged in frame and is elevated, and can pass the stamping station 10 of pressing component, ensure that ejector beam 1 moves 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 with contiguous block 3 pivot joint in holding tank, and described cam and roller 5 push up presses, and certain roller 5 can adopt bearing.
As shown in the figure, cam 4 comprises the first half takes turns 8 and the second half and takes 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 shaft 2, first semi-ring fixed part 6 and the second semi-ring fixed part 7 are connected by screw and locking power transmission shaft 2, pass through said structure, cam 4 can be easily installed on power transmission shaft 2 and to dismantle, and what is more important, pass through said structure, relative position between each cam 4 can regulate by free setting, because, workpiece itself may be have concaveconvex shape or in stamping station, be placed with multiple workpiece, differ in the pressure position, top that every root ejector beam 1 pushes up pressure workpiece, thus ejector beam 1 moves to also not identical with the stroke at the pressure place, top of workpiece, but in order to ensure the uniform force of workpiece, just need the ejector beam 1 of the same workpiece of top pressure to force on this workpiece simultaneously, just must be realized by the relative position adjusted between each cam 4, when initial position, the convex arc of each cam 4 arranges and is positioned at different positions, need Long travel could with absorption surface ejector beam 1 first can contact with the convex arc of corresponding cam 4, need short stroke could with absorption surface ejector beam 1 can contact with after the convex arc of corresponding cam 4, thus after power transmission shaft 2 turns an angle, all ejector beams 1 can contact with surface of the work simultaneously exert a force and push up and press workpiece by workpiece from mold ejection.
Above-mentionedly just preferred embodiments more of the present invention are illustrated and described, but embodiments of the present invention are not restricted to the described embodiments, as long as it reaches technique effect of the present invention with substantially identical means, all should belong to protection scope of the present invention.
