Background technology
At present, straightening press is divided into friction press and the large class of hydraulic press two.Friction press belongs to big-and-middle-sized equipment, because forcing press totipotency in use is comparatively large, and install, handiness, therefore press workshop, forge all extensively adopt, but its to use security very poor, power consumption is also very large.Hydraulic press in recent years usage quantity constantly increases, and it can adjust stroke, pressure, speed at any time; But if will meet forcing press lost motion rapid movement simultaneously, course of exerting pressure is slow, large requirement of exerting pressure, and system can be very complicated, and fault rate is high, and care and maintenance also becomes very difficult.Such as: the standard configuration motor of 100 tons of forcing presses is 15 kilowatts, equal rate request, and the forcing press motor of 150 tons will select 22 kilowatts, because the increase of power of motor, the electrical system of control system all will be upgraded, and the input of equipment will increase.Existing straightening press can not only loss-rate higher, and the pressure that common straightening press exports can not meet the pressure demand of some workpiece.
Summary of the invention
For above-mentioned prior art Problems existing, the invention provides a kind of toggle joint type straightening press, effectively can reduce energy consumption, only need the thrust that hydraulic jack provides very little, just can apply larger pressure to workpiece.
To achieve these goals, the technical solution used in the present invention is: a kind of toggle joint type straightening press, comprise rectangular susceptor, workbench, sliding clamp, connecting rod and hydraulic jack, workbench is arranged on rectangular susceptor top, workbench is provided with two holes perpendicular to table top, the lower end of connecting rod is fixedly connected in hole, sliding clamp is slidably connected on connecting rod, also comprise movable top plate and toggle device, movable top plate is slidably connected at the upper end of connecting rod, the bottom of movable top plate is connected with one end of toggle device, the other end of toggle device is connected with sliding clamp, hydraulic jack is connected with the middle part of toggle device, described toggle device is made up of four toggles, each toggle is by strand fixed connecting plate, upper backup pad, lower supporting plate and double-strand fixed connecting plate composition, strand fixed connecting plate is connected with the upper end of upper backup pad by pivot pin, the lower end of upper backup pad is connected with the upper end of lower supporting plate by pivot pin, the lower end of lower supporting plate is connected with double-strand fixed connecting plate.
Further, movable top plate is also provided with arrangement for adjusting height, described height adjuster comprises fluid pressure drive device, sprocket wheel, L-type frame leg and connecting plate, L-type frame leg and connecting plate are fixed in the groove of removable top board, connecting plate is fixedly connected on the top of L-type frame leg, fluid pressure drive device is fixedly connected with connecting plate, sprocket wheel is connected with fluid pressure drive device, sprocket wheel is connected with left Height Adjustment nut by the first chain, and left Height Adjustment nut is connected with right Height Adjustment nut by the second chain.
Compared with prior art, the present invention adopts toggle device, effectively can not only reduce energy consumption, and the thrust simultaneously only needing hydraulic jack to provide very little, just can make this device convert larger pressure to by toggle.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As Fig. 1, Fig. 2, shown in Fig. 3, the present invention includes rectangular susceptor 1, workbench 2, sliding clamp 3, connecting rod 19 and hydraulic jack 4, workbench 2 is arranged on rectangular susceptor 1 top, workbench 2 is provided with two holes perpendicular to table top, the lower end of connecting rod 19 is fixedly connected in hole, sliding clamp 3 is slidably connected on connecting rod 19, also comprise movable top plate 8 and toggle device 5, movable top plate 8 is slidably connected at the upper end of connecting rod 19, the bottom of movable top plate 8 is connected with one end of toggle device 5, the other end of toggle device 5 is connected with sliding clamp 3, hydraulic jack 4 is connected with the middle part of toggle device 5, described toggle device 5 is made up of four toggles, each toggle is by strand fixed connecting plate 15, upper backup pad 16, lower supporting plate 17 and double-strand fixed connecting plate 18 form, strand fixed connecting plate 15 is connected by the upper end of pivot pin with upper backup pad 16, the lower end of upper backup pad 16 is connected by the upper end of pivot pin with lower supporting plate 17, the lower end of lower supporting plate 17 is connected with double-strand fixed connecting plate 18.
As a modification of the present invention, movable top plate 8 is also provided with arrangement for adjusting height, height adjuster comprises fluid pressure drive device 6, sprocket wheel 7, L-type frame leg 13 and connecting plate 12, L-type frame leg 13 and connecting plate 12 are fixed in the groove of removable top board 8, connecting plate 12 is fixedly connected on the top of L-type frame leg 13, fluid pressure drive device 6 is fixedly connected with connecting plate 12, sprocket wheel 7 is connected with fluid pressure drive device 6, sprocket wheel 7 is connected with left Height Adjustment nut 9 by the first chain 10, and left Height Adjustment nut 9 is connected with right Height Adjustment nut 14 by the second chain 11.When needing highly to regulate, fluid pressure drive device 6 drives left Height Adjustment nut 9 and right Height Adjustment nut 14 to rotate, and by the external screw thread on connecting rod 19, realizes sliding clamp 3 and adjusts with the spacing of workbench 2.
During work, when hydraulic jack 4 stretching routine, toggle device 5 stretches, and sliding clamp 3 is descending, realizes downward pressure; When hydraulic jack 4 contractile motion, toggle device 5 bends, and sliding clamp 3 is up, realizes resetting.This device uses very low power hydraulic jack to promote elbow joint, then by the stretching, extension of elbow joint, amplifies operating pressure, time particularly toggle is about to stretch, force value straight line rises, and this section of operating distance is between 0 ~ 30mm, and this is the region that bends of most of workpiece and sheet material just; In addition, the curve movement rule of toggle is: when toggle is open, and movement velocity is very fast, and when being close to straight configuration, movement velocity is very slow, is just applicable to the feature of alignment; Effectively can not only reduce energy consumption like this, but also larger pressure can be produced carry out alignment.
