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 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 after workpiece workpiece from mold ejection in forging and pressing, 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, turn round to push up by cam and press the ejector beam motion, when rotating by cam, the variation of the radian of outer makes ejector beam produce lifting travel,, good rigidly high because of the cam rotating speed, thereby the speed of its liftout is fast, and efficient 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, be hubbed at the power transmission shaft on frame, be installed with some cams on described power transmission shaft, pressure is pushed up mutually with ejector beam in the outer of described cam, thereby makes ejector beam increase.
Described ejector beam guides and lifting by the linear bearing that is arranged in 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 with the contiguous block pivot joint in holding tank, and press on described cam and roller top.
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.
Described the first semi-ring fixed part and the second semi-ring fixed part are connected by screw and the locking power transmission shaft.
The invention has the beneficial effects as follows: the present invention includes some ejector beams, be hubbed at the power transmission shaft on frame, be installed with some cams on described power transmission shaft, pressure is pushed up mutually with ejector beam in the outer of described cam, thereby make ejector beam increase, turn round to push up by cam and press the ejector beam motion, when rotating by cam, the variation of the radian of outer makes ejector beam produce lifting travel,, good rigidly high because of the cam rotating speed, thereby the speed of its liftout is fast, and efficient is high, and simple in structure being easy to safeguarded.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is three-dimensional view of the present invention;
Fig. 2 is cutaway view of the present invention.
The specific embodiment
With reference to Fig. 1, Fig. 2, the invention discloses a kind of cam material jacking mechanism, comprise some ejector beams 1, be hubbed at the power transmission shaft 2 on frame, be installed with some cams 4 on described power transmission shaft 2, pressure is pushed up mutually with ejector beam in the outer of described cam 4, thereby makes ejector beam 1 increase.
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 frame, and can pass the punching press platform 10 of pressing component, 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 with contiguous block 3 pivot joints in holding tank, and press on described cam and roller 5 tops, 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 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 dismounting, and what is more important, pass through said structure, the relative position that each cam is 4 can be regulated by free setting, because, workpiece itself may be have a concaveconvex shape or be placed with a plurality of workpiece on the punching press platform, the top of every ejector beam 1 top pressure workpiece presses the position to differ, thereby ejector beam 1 moves to also not identical with the stroke at the pressure place, top of workpiece, but in order to guarantee the stressed even of workpiece, just need the top to press the ejector beam 1 of same workpiece to force in simultaneously on this workpiece, just must realize by the relative position of adjusting 4, each cam, when initial position, the convex arc setting of each cam 4 is positioned at different positions, need long stroke could with workpiece contact ejector beam 1 can first contact with the convex arc of corresponding cam 4, 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 turns an angle, all ejector beams 1 can simultaneously contact the application of force with surface of the work and push up the pressure workpiece with workpiece from mold ejection.
Above-mentionedly just preferred embodiments more of the present invention are illustrated and describe, 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 essentially identical means, all should belong to protection scope of the present invention.
