Description
Technical field
The invention belongs to mechanical field, relate to a kind of driven type double-station punching machine, especially horizontal digital-control double-station punching machine.
Background technology
At present, traditional mechanical press is all vertical.On vertical punching machine, realize double-station punching or double-station punching is more difficult, often need a numerical control table, NC table; Adopt the double vertical punching of numerical control table, NC table, structurally more complicated, the rigidity of workbench is poor; In addition, the cost of whole system is also higher.Modern manufacturing industry, the particularly manufacture of the product such as electronic apparatus, communication, more and more urgent to the demand of high efficiency, low power automatic stamping machine, and traditional mechanical press obviously can not meet this demand.
Summary of the invention
In order to solve the problem, the invention provides the driven type double-station punching machine that a kind of structure is simple, intellectually and automatically degree is high, production efficiency is high.
Technical scheme of the present invention is to provide a kind of driven type double-station punching machine, it comprises lathe and two punching press stations, it is characterized in that: the drive unit described lathe being arranged power input element and drive described power input element to rotate around own axes, the two ends of described power input element respectively arrange a leading screw, described in two, the axis of leading screw is located along the same line, and described in two, the thread rotary orientation of leading screw is contrary, helical pitch is identical; Each described leading screw is all threaded a nut, each described nut is all fixed a hinged slide; Each described punching press station all arranges a drift slide block, and drift slide block described in two is with the axis of described leading screw for symmetry axis is symmetrical arranged, and all hinged two toggle links on each described drift slide block, the other end of toggle link described in two distinguishes hinged slide described in hinged.
Preferably, described drive unit is servomotor, and described drive unit is rotated by power input element described in synchronizing jugged belt wheel or gear drive.
Preferably, described lathe is horizontal symmetric configuration.
Preferably, described punching press station place is provided with mould, between two described drift slide blocks and mould, be provided with the guide groove led to workpiece to be processed.
Preferably, described leading screw is ball-screw, is provided with ball between described nut and described leading screw, described leading screw is provided with the spirality raceway rolled for described ball.
Preferably, at the end of the punching press of described drift slide block, toggle link described in two is perpendicular to described leading screw.
The original symmetry realized by the mechanical driving device of complexity is synchronized with the movement and becomes intelligent and flexibility by driven type double-station punching machine of the present invention; Be equipped with and be synchronized with the movement in the symmetry of two slide blocks, pass to two drift slide blocks by symmetrical toggle link, thus constitute a kind of novel numerical-control double-station stamping machine.This stamping machine has the elbow-bar mechanism in traditional mechanical press, can in press work process, and realizable force amplifies; Also when drift returns, stroke can be realized and amplifies.Owing to adopting the force design of full symmetric, the side force suffered by drift slide block is zero in theory.Therefore, relative to traditional mechanical press bearing side force, the service life of its drift slide block obtains and increases substantially.In addition, owing to adopting the mode of double punching press simultaneously, production efficiency is greatly improved.Because lathe adopts horizontal layout, relative to traditional vertical punching lathe, center of gravity is low, good stability.In addition, in lathe both sides, the step device of self-feeding is set, the press machine of high efficiency, automation can be formed.
Accompanying drawing explanation
Structural representation when Fig. 1 is the state to be punched of driven type double-station punching machine most preferred embodiment of the present invention;
Structural representation when Fig. 2 is the punching press completion status of driven type double-station punching machine most preferred embodiment of the present invention.
Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of driven type double-station punching machine of the present invention comprises lathe (not shown) and two punching press stations 10 of horizontal symmetric configuration, punching press station 10 in the present embodiment is the structure of drawing quality steel sheet shape material, punching press station 10 place is provided with mould 12, is provided with the guide groove 14 led to workpiece to be processed between two drift slide blocks 26 and mould 12.Certainly, the present invention also can be applied to the material of other structures of punching press, and this is all the improvement that those of ordinary skill in the art's content according to the present invention is easy to expect.The drive unit (not shown) lathe being arranged power input element 16 and drive power input element 16 to rotate.Drive unit can adopt servomotor or common electric machine.Drive unit is rotated by synchronizing jugged belt wheel or gear drive power input element 16.
Power input element 16 is a cylinder, and the axis that its two ends respectively arrange leading screw 18,20, two leading screw 18,20 is located along the same line, and two leading screws 18,20 are provided with the screw thread that rotation direction is contrary, helical pitch is identical.Certainly, those of ordinary skill in the art can also according to mentality of designing of the present invention, design new departure that multistage screw thread is set on leading screw 18,20, only guarantee that screw thread is symmetricly set on two leading screws 18,20 for symmetric points with power input element 16, so just can realize 4 stations, 6 stations ...For two stations of the present embodiment, each leading screw 18,20 is all threaded a nut 221,222, each nut 221,222 is all fixed a hinged slide 24; Each punching press station 10 all arranges drift slide block 26, a two drift slide block 26 with the axis of leading screw 18,20 for symmetry axis is symmetrical arranged, the other end of all hinged two toggle link 28, a two toggle links 28 hinged hinged slide 24 respectively on each drift slide block 26.Its operation principle is, by drive unit drive power input element 16 rotate, drive nut 221,222 along leading screw 18,20 relative to or move on the contrary.When nut 221,222 is synchronized with the movement inwards simultaneously, the toggle link 28 be hinged on hinged slide 24 will promote two drift slide blocks 26 and move to workpiece direction.Because toggle link 28 mechanism is a stroke amplifying mechanism when its pressure angle is larger, be then force amplificatory structure when its pressure angle is less, therefore, lathe can realize rapid movement during idle stroke, and larger power output during impulse stroke; Pressure angle is less, and stamping press is larger.After punching course terminates, nut 221,222 is outwards synchronized with the movement simultaneously, and the toggle link 28 be hinged on hinged slide 24 will drive two drift slide blocks 26 to leaving the motion of workpiece direction, realizes returning fast.
Further, leading screw 18,20 is ball-screw, better reduces noise to obtain, and improves the effect of transmission efficiency.
Further, at the end of drift slide block 26 punching press, two toggle links 28, perpendicular to leading screw 18,20, to raise the efficiency to greatest extent, save the stroke of toggle link 28.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
