The working thrust forces of two oil cylinders are superposed to increase the upward turning force of a reverse turning bed, the oil mass of the two oil cylinders are supplied by a hydraulic pressure source, the respective oil mass is adjusted automatically, and each oil cylinder takes the oil mass required by the same oil cylinder.
Description
Affiliated technical field
The utility model relates to a kind of turnover panel power multi-bar linkage of tilting plate type steel plate bender, especially has two actuator cylinders in a cover multi-bar linkage, has increased the required power of sheet material bending.
Background technology
Because the tilting plate type bender is compared with other form benders. the sheet material with folding different angles does not need the more advantage of mold exchange, so the tilting plate type bender is promoted thus.The every cover multi-bar linkage of present known tilting plate type steel plate bender all has only an actuator cylinder, and the power of turning over is restricted on the turnover panel.This directly limits the thickness of bending plate.
Summary of the invention
For overcome general multi-bar linkage exert oneself little can only bending than the steel-sheet deficiency, the utility model provides in a kind of cover multi-bar linkage has the multi-bar linkage that two actuator cylinders are worked simultaneously, thereby make turnover panel on the power of turning over obtain increasing, thicken the thickness of bending plate.
The technical scheme that its technical problem that solves the utility model adopts is:
One, structure and course of action: have two actuator cylinders in the cover multi-bar linkage and work simultaneously, the working thrust stack of two oil cylinders realizes the increase of the power of turning on the turnover panel.
(1.) promoting mainly the hinged of oil cylinder is installed on the frame, piston rod links to each other with the fulcrum of power rail, fixed bar is fixed on the lower jaw plate, the lower jaw plate links to each other with frame, swing arm is fixed on the turnover panel, the hinged tail end that is installed in power rail of secondary push oil cylinder, piston rod links to each other with the swing arm fulcrum, other three fulcrums of power rail respectively with the fulcrum of the centre of intermediate bar, the fulcrum of connecting rod A, another fulcrum of swing arm links to each other, the fulcrum at intermediate bar two respectively with fixed bar, the fulcrum of connecting rod B links to each other, fulcrum of the other end fulcrum of connecting rod B and the centre of swing arm links to each other, another fulcrum of another fulcrum and fixed bar of connecting rod A links to each other, being connected between bar and the bar, bar all is hinged connection with being connected of oil cylinder piston bar.
(2.) workpiece is pressed on the lower jaw plate by the upper jaw plate, pressure oil enters simultaneously promotes mainly oil cylinder and secondary push oil cylinder, promotes mainly oil cylinder power rail is upwards promoted, and meanwhile secondary push oil cylinder is drawn back the distance between the tail end of the tail end of power rail and swing arm, make on the turnover panel and turn over, workpiece has this and bending.
Two, hydraulic system: the oil mass of two oil cylinders has a hydraulic pressure source to provide, and automatically regulates separately oil mass, each takes what he needs.
The beneficial effects of the utility model are, have two actuator cylinders in the cover multi-bar linkage and work simultaneously, the power of two oil cylinders in a cover multi-bar linkage, change into turnover panel on turn over power.If double dynamical multi-bar linkage is installed in respectively on the identical tilting plate type bender with general multi-bar linkage, the thickness of slab of double dynamical multi-bar linkage bender bending is greater than general multi-bar linkage bender.

The specific embodiment
From Fig. 2 to Fig. 1, be the overall process of mechanism work from 1 to Fig. 3 again.Promoting mainly the hinged of oil cylinder (7) is installed on the frame (11), piston rod links to each other with the fulcrum of power rail (4), fixed bar (1) is fixed on the lower jaw plate (9), the lower jaw plate links to each other with frame (11), swing arm (2) is fixed on the turnover panel (10), the hinged tail end that is installed in power rail (4) of secondary push oil cylinder (8), piston rod links to each other with swing arm (2) fulcrum, other three fulcrums of power rail (4) respectively with the fulcrum of the centre of intermediate bar (3), the fulcrum of connecting rod A (5), another fulcrum of swing arm (2) links to each other, the fulcrum at intermediate bar (3) two respectively with fixed bar (1), the fulcrum of connecting rod B (6) links to each other, the other end fulcrum of connecting rod B (6) links to each other with fulcrum in centre of swing arm (2), and another fulcrum of connecting rod A (5) links to each other with another fulcrum of fixed bar (1).Being connected between bar and the bar, bar all are hinged connections with being connected of oil cylinder piston bar.In Fig. 1 to Fig. 3, workpiece (13) is pressed on the lower jaw plate (9) by upper jaw plate (12), pressure oil enters simultaneously promotes mainly oil cylinder (7) and secondary push oil cylinder (8), promoting mainly oil cylinder (7) upwards promotes power rail (4), meanwhile secondary push oil cylinder (8) is drawn back the distance between the tail end of the tail end of power rail (4) and swing arm (2), makes on the turnover panel (10) and turns over.Because the restraining function of connecting rod A (5), connecting rod B (6) and intermediate bar (3) is arranged, around intersection point rotation, this intersection point is the common intersection of lower jaw plate (9), turnover panel (10), upper jaw plate (12) to turnover panel all the time in the process of turning on turnover panel.Workpiece (13) has this and bending.Be installed with the same mechanism of many covers on the lower jaw plate of a bender side by side.
The speed that ejects of two oil cylinders is pind down mutually, and speed is not interfered, and the required oil mass of two oil cylinders is wanted and can be regulated automatically in the hydraulic system of Fig. 4.Have hydraulic principle as can be known: do not have again when in a certain hydraulic system a plurality of actuator being arranged under the prerequisite of pressure valve control, the hydraulic oil preferential flow is to the less actuator of load, when overflow valve when being normally closed system pressure be to set up by the bigger actuator of load.
The oil mass of two oil cylinders is self-regulating like this: suppose to promote mainly oil cylinder (7) load greater than secondary push oil cylinder (8), at this moment promote mainly the required speed of the secondary relatively push oil cylinder of the required speed of oil cylinder the trend of slowly getting off is arranged, hydraulic oil will be more the less secondary push oil cylinder (8) of flow direction load, the speed of secondary push oil cylinder will be risen progressively, and load also increases thereupon.If the speed of secondary push oil cylinder rise progressively load is surpassed promote mainly oil cylinder (7), hydraulic oil again can more flow direction load less promote mainly oil cylinder (7).The self-regulating principle of procedure declaration oil mass of above-mentioned hypothesis, regulating does not automatically in actual use have surrounding time poor.
Because promoting mainly the effect of oil cylinder (7) and secondary push oil cylinder (8) all is to make on the turnover panel to turn over, can both operate as normal so shed wherein any one oil cylinder mechanism, this thrust that just can prove two oil cylinders is overlaying relations, turns over the increase of power on the realization turnover panel.
Overflow valve in the hydraulic system of Fig. 4 (14) is normally closed, reversal valve (15) does not install pressure-control valve additional to the pressure oil pipe of two oil cylinders, and, so more help the automatic adjusting of oil cylinder oil mass nearby being divided into two, passing to respectively and promote mainly oil cylinder 7 and secondary push oil cylinder 8 near two oil cylinder places.
