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 that adopts brace and connecting rod framework.
Background technology
At present, traditional mechanical stamping machine is all vertical.On vertical punching machine, it is more difficult realizing double-station punching or multiple site punching, often needs a numerical control table, NC table; Adopt the double vertical punching of numerical control table, NC table, more complicated structurally, 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 stamping machine obviously can not meet this demand.In addition,, in machinery manufacturing industry, hydraulic transmission technology and air pressure drive technology are applied very extensive in stamping machine.Hydraulicdriven power output is very large, but transmission efficiency is lower, and hydraulic drive take hydraulic oil as working media, the phenomenon that there will be fluid volatilization and reveal, thus environment is caused to larger pollution.Pneumatic Transmission stable action, cost are lower, and adopt free of contamination air as working media, can be to environment.But it is lower that air-driven shortcoming is exactly operating pressure, be generally 0.5Mpa left and right.In the larger occasion of ask for something power output, can cause the increase of volume and the cost of device.
Summary of the invention
In order to address the above problem, the invention provides a kind of needs to adopt air compressor or hydraulic pump, general arrangement is simple in structure, High power output, the driven type double-station punching machine of the employing brace and connecting rod framework of non-environmental-pollution.
Technical scheme of the present invention is to provide a kind of driven type double-station punching machine that adopts brace and connecting rod framework, it comprises lathe and two punching press stations, it is characterized in that: a motor is set on described lathe, the coaxial leading screw that connects of output shaft of described motor, on described leading screw, screw thread is socketed a nut, on described nut along described leading screw length direction two tooth bars that are connected, on described lathe, take described leading screw as symmetry axis be symmetrical arranged two respectively with tooth bar meshed gears described in; Described in two, punching press station be take described leading screw and is symmetricly set on the both sides of described screw mandrel as symmetry axis, described in each, punching press station all arranges a chute, in described chute, be provided with movably drift slide block, described in each, drift slide block is all connected to described gear eccentric position place by a toggle, and described toggle and described gear and drift slide block are all hinged.
Preferably, described motor is servomotor.
Preferably, described lathe is horizontal symmetric configuration.
Preferably, described leading screw is ball-screw, between described nut and described leading screw, is provided with ball, is provided with the spirality raceway rolling for described ball on described leading screw.
The driven type double-station punching facility of employing brace and connecting rod framework of the present invention have following beneficial effect:
(1) technical functionality is comparatively perfect, adopts the screw-nut body, pinion and rack, toggle mechanism of technology maturation as the main element of stamping machine, and processing and manufacturing is got up more for convenience.
(2) motor-guilde screw drive technology have that stable working, transmission efficiency are high, High power output, the advantage such as pollution-free, the present invention adopts motor-guilde screw drive technology to drive, replace easily producing hydraulic transmission technology and the less Pneumatic Transmission technology of power output of polluting, meet trend and the trend of greenization future development.
(3) only adopt a set of motor-guilde screw transmission device, just realized the work of two stations, structure is compacter, has improved operating efficiency, has reduced cost.
(4) toggle in this device is non-linear mechanism, and when drive line angle, pressure angle are large, toggle can be used as stroke amplifying mechanism, and now output speed is large, and the speed of crossing idle stroke is fast, has saved the time.When drive line angle, pressure angle are little, can be used as force amplificatory structure, now output speed is little, but power output is very large, and now the power output of stamped workpieces has also obtained guarantee.
(5), due to the horizontal layout of machine adopted, with respect 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, can forms the press machine of high efficiency, automation.
(6) adopt double structure, stress balance, extending structure life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation that the present invention adopts the driven type double-station punching machine most preferred embodiment of brace and connecting rod framework.
The specific embodiment
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, a kind of driven type double-station punching machine that adopts brace and connecting rod framework of the present invention comprise lathe (not shown) and two punching press stations 1,1 '.Two punching press stations 1,1 ' be symmetrical arranged wherein, still, also can be according to mentality of designing of the present invention, by a plurality of punching press station one side settings or symmetrically arranged punching press stations of many groups etc. are set.One motor 2 is set on lathe, the coaxial leading screw 3 that connects of output shaft of motor 2, on leading screw 3, screw thread is socketed a nut 4.In the present embodiment, on nut 4, be socketed a two-sided rack, i.e. a tube-in-tube structure, its both sides are provided with tooth bar 5.On lathe, also arrange two respectively with tooth bar 5 meshed gears 6,6 ', gear 6,6 ' under the driving of tooth bar 5 is around self axis rotation; Each punching press station 1,1 ' all arrange chute 7,7 ', chute 7,7 ' be inside provided with movably drift slide block 8,8 ', each drift slide block 8,8 ' is all by a toggle 9,9 ' be connected to gear 6,6 ' eccentric position place, toggle 9,9 ' with gear 6,6 ' and drift slide block 8,8 ' all hinged.
Further, drive unit is servomotor 2, and general motor is good, but servomotor 2 is convenient to accurate control.
