Description
Technical field
The utility model belongs to mechanical field, relates to a kind of piston 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, often needs 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 stamping machine obviously can not meet this demand.
Summary of the invention
In order to address the above problem, the utility model provides a kind of horizontal, piston type double-station punching machine of adopting efficiently brace and connecting rod framework.
The technical solution of the utility model is to provide
A kind of piston 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: two-piston formula driving mechanism is set on described lathe along a straight line, one connecting rod connects the piston of driving mechanism described in two, on described connecting rod, be provided with along its length two tooth bars, two and described tooth bar meshed gears are also set on described lathe; Described gear and punching press station, all taking described connecting rod as symmetry axis, are symmetricly set on the both sides of described connecting rod; Each described punching press station all arranges a chute, is provided with movably drift slide block in described chute, and each described 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 piston type driving mechanism is oil cylinder or cylinder.
Preferably, on described lathe, arrange two described in punching press station, described in two, punching press station is symmetrical arranged taking the axis of described connecting rod as symmetry axis, two are symmetrical arranged taking the axis of described connecting rod as symmetry axis with described tooth bar meshed gears respectively.
Preferably, described lathe is horizontal symmetric configuration.
The piston type double-station punching facility of employing brace and connecting rod framework of the present utility model have following beneficial effect:
(1) technical functionality is comparatively perfect, adopts the 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) only adopt a set of transmission device, just realized the work of two stations, structure is compacter, has improved operating efficiency, has reduced cost.
(3) toggle in this device is non-linear mechanism, and in the time that 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.In the time that 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.
(4), 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.
(5) when adopting cylinder during as driving mechanism, its have be swift in motion, cost is lower, and to adopt clean compressed air be working media, can not cause the advantage such as pollution of environment.
(6) adopt double structure, stress balance, extending structure life-span.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model adopts the piston type double-station punching machine most preferred embodiment of brace and connecting rod framework.
Detailed description of the invention
Below detailed description of the invention of the present utility model is described in further detail.
As shown in Figure 1, a kind of piston type double-station punching machine that adopts brace and connecting rod framework of the present utility model comprises lathe (not shown), and two oil cylinders or cylinder are set on lathe, preferably cylinder.Cylinder 1 and cylinder 1 ' along same straight line setting, piston 2 and piston 2 ' relative, a connecting rod 3 connect piston 2 and piston 2 '.Two punching press stations 4 are set taking connecting rod 3 as symmetry axis.Two punching press stations 4 are symmetrical arranged, and still, also can, according to mentality of designing of the present invention, organize symmetrically arranged punching press stations etc. by multiple punching press station one side settings or arrange more.Each punching press station 4 all arranges a chute 5, is provided with movably drift slide block 6 in chute 5.
On connecting rod 3, arrange tooth bar 7 and tooth bar 7 ', tooth bar 7 and tooth bar 7 ' be separately positioned on the both sides of connecting rod 3 taking connecting rod 3 as axle, can certainly be arranged to two sides rack structure by connecting rod 3.Gear 8 and gear 8 ' be engaged on a respectively tooth bar 7 and tooth bar 7 ' upper, tooth bar 7 and tooth bar 7 ' driving under around self axis rotation.Each drift slide block 6 is by a toggle 9 and toggle 9 ' be connected to gear 8 and gear 8 ' eccentric position place, toggle and gear 8 and gear 8 ' and drift slide block 6 is all hinged.
Operation principle of the present utility model: when compressed air enters cylinder 1, promotion lower piston 2 and piston 2 ' move upward, thereby band carry-over bar 7 and tooth bar 7 ' move upward, tooth bar 7 and tooth bar 7 ' drive two side gears 8 and gear 8 ' do respectively clockwise and motion counterclockwise, and then promotion both sides toggle, drive two drift slide blocks 6 outwards to move, by the punch on drift slide block 6, left and right workpiece is carried out to punching press.
When compressed air enter upper cylinder 1 ', promotion upper piston 2 and piston 2 ' move downward, this hour rack 7 and tooth bar 7 ' move downward, thereby drive two side gears 8 and gear 8 ' do respectively to move counterclockwise and clockwise, drive the toggle of both sides, drive drift slide block 6 to move inward, reset.
Due in punching course, the stamping press of two stations in left and right, reacts to the cross force on the two-sided rack, is symmetrical balance.So this stamping machine is with respect to the single station stamping machine that adopts single rack-crank-connecting-rod force increasing device, not only 1 times of production efficiency raising, and the stress condition of tooth bar and piston is greatly improved, and can increase substantially service life.
Above embodiment is only the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
