Description
Technical field
The invention belongs to mechanical field, relate to a kind of driven type double-station punching machine adopting brace and connecting rod framework, 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 multiple site 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.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 is working media with hydraulic oil, the phenomenon that there will be fluid volatilization and reveal, thus causes larger pollution to environment.Pneumatic Transmission stable action, cost are lower, and adopt free of contamination air as working media, can not to environment.But it is lower that air-driven shortcoming is exactly operating pressure, is generally about 0.5Mpa.In the occasion that ask for something power output is larger, the volume of device and the increase of cost can be caused.
Summary of the invention
In order to solve the problem, the invention provides one does not need to adopt air compressor or hydraulic pump, and general arrangement structure is simple, 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 adopting brace and connecting rod framework, it comprises lathe and two punching press stations, it is characterized in that: described lathe is arranged a motor, the output shaft of described motor coaxially connects a leading screw, on described leading screw, screw thread is socketed a nut, described nut to be connected two tooth bars along described leading screw length direction, on described lathe with described leading screw for symmetry axis be symmetrical arranged two respectively with tooth bar meshed gears described in; Described in two, punching press station is with the both sides of described leading screw described screw mandrel for symmetry axis is symmetricly set on, each described punching press station all arranges a chute, drift slide block is provided with movably in described chute, each described drift slide block is all connected to described gear eccentricity position by a toggle, described toggle and described gear and drift slide block all hinged.
Preferably, described motor is servomotor.
Preferably, described lathe is horizontal symmetric configuration.
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.
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, and adopt the screw-nut body of technology maturation, pinion and rack, toggle mechanism as the main element of stamping machine, processing and manufacturing is got up more for convenience.
(2) motor-guilde screw drive technology has 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 the hydraulic transmission technology that pollutes and the less Pneumatic Transmission technology of power output, meet trend and the trend of greenization future development.
(3) only adopt a set of motor-guilde screw transmission device, just achieve the work of two stations, structure is compacter, improves operating efficiency, reduces cost.
(4) toggle in this device is non-linear mechanism, and when drive line angle, pressure angle are large time, toggle can as stroke amplifying mechanism, and now output speed is large, and the speed of crossing idle stroke is fast, saves the time.When drive line angle, pressure angle are little time, 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 have also been obtained guarantee.
(5) 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.
(6) double structure is adopted, 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.
Detailed description of the invention
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 of brace and connecting rod framework that adopts of the present invention comprises lathe (not shown) and two punching press stations 1,1 '.Wherein two punching press stations 1,1 ' are symmetrical arranged, but, also according to mentality of designing of the present invention, multiple punching press station side can be arranged or symmetrically arranged punching press station of many groups etc. is set.Lathe is arranged a motor 2, the output shaft of motor 2 coaxially connects a leading screw 3, and on leading screw 3, screw thread is socketed a nut 4.In the present embodiment, nut 4 is socketed a two-sided rack, i.e. a tube-in-tube structure, its both sides are provided with tooth bar 5.Lathe is also arranged two respectively with tooth bar 5 meshed gears 6,6 ', gear 6,6 ' rotates around own central axis line under the driving of tooth bar 5; Each punching press station 1,1 ' all arranges a chute 7,7 ', chute 7,7 ' is interiorly provided with drift slide block 8,8 ' movably, each drift slide block 8,8 ' is all connected to gear 6,6 ' eccentric position place by a toggle 9,9 ', toggle 9,9 ' and 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.
Further, lathe is horizontal symmetric configuration.
Further, leading screw 3 is ball-screw, is provided with ball 9 between nut 4 and leading screw 3, leading screw 3 is provided with the spirality raceway (not shown) rolled for ball 9.This structure contributes to Power output and reduces noise.
Operation principle of the present invention is: when motor 2 rotates backward, leading screw 3 is driven also to do reverse rotation, ball 9 between leading screw 3 and nut 4 is successively along rolling path rolling, thus promotion nut 4 does rectilinear motion upwards, this hour rack 5 also does motion upwards, tooth bar 5 drives the gear 6 in left side to make clockwise movement, and counterclockwise movement made by the gear 6 ' on right side.Gear 6,6 ' promotes crank connecting link 9, the 9 ' mechanism of both sides again, drives left and right drift slide block 8,8 ' outwards to move and carries out punching press.After work pieces process, motor 2 is rotated forward, then leading screw 3 rotates forward, nut 4 makes downward rectilinear motion with carry-over bar 5, tooth bar 5 drives that left and right gear 6,6 ' is done counterclockwise respectively, clockwise movement, and by crank connecting link 9,9 ', mechanism makes the workpiece of completion of processing be unclamped.
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.
