Detailed description of the invention
As shown in Fig. 1 Fig. 7, forcing press quick die change dolly for the present invention, including vehicle frame 1, bottom of frame is provided with roller 21, the mould bases guide rail 2 that left and right is parallel it is provided with on the upside of vehicle frame 1, vertically it is provided with the parallel bearing roller of two rows 3 between mould bases guide rail 2, in vehicle frame 1, is additionally provided with trolley driving mechanism, braking mechanism, mould bases push-pull mechanism, mould bases detent mechanism and mould bases elevating mechanism；Trolley driving mechanism is for driving dolly to walk on the track coordinated with it；Mould bases push-pull mechanism is for drawing in dolly from press bench along mould bases guide rail 2 by mould bases or pushing to press bench from dolly, mould bases detent mechanism is used for fixing mould bases position on mould bases guide rail 2, mould bases elevating mechanism is for lifting the road wheel 19A being in contact with it bottom mould bases thus the height reducing mould bases 19, make mould bases bottom surface contact with bearing roller 3, in order to mould bases 19 along bearing roller 3 laterally out of mold-change trolley.
For ease of realizing the motion of mold-change trolley, as in figure 2 it is shown, trolley driving mechanism includes that reductor 1, the outfan of reductor 1 are provided with sprocket wheel 1, it is coaxially connected with sprocket wheel 2 11, sprocket wheel 1 and sprocket wheel 2 11 on roller 21 bottom dolly to be in transmission connection by chain 1.
Accurate stopping for ease of mold-change trolley, as shown in Figure 3, braking mechanism includes being arranged on friction roller 16 on roller shaft, and the periphery of friction roller 16 is fixed with brake cylinder 14, for holding the brake shoes 15 of friction roller 16 tightly when the piston-rod end of brake cylinder 14 is provided with brake.For realizing accurate stopping further, brake shoes 15 and brake cylinder 14 are arranged with two groups along the diametric(al) of friction roller 16.
For ease of by mould bases 19 into and out mold-change trolley, as shown in Figure 3, mould bases push-pull mechanism includes the sprocket wheel link chain mechanism driven by reductor 27, the chain 2 13 of sprocket wheel link chain mechanism is set in parallel between mould bases guide rail 2, movable stand 17 it is fixed with on chain 2 13, the downside cooperation of movable stand 17 is provided with slide rail, and movable stand 17 is additionally provided with the hook 18 being easy to draw mould bases.After in mechanism, the hook 18 on movable stand hooks mould bases 19, reductor 27 drive sprocket link chain mechanism moves, and drives movable stand 17 to move along slide rail, thus drawn to mold-change trolley by mould bases 19 during chain 2 13 motion.
During for preventing mold-change trolley from moving, mould bases 19 vibration on mold-change trolley, mould bases detent mechanism includes for positioning die carrier 19 liftable limited post 8 of position on mold-change trolley, control lifting by cylinder bottom limited post 8, vehicle frame 1 is additionally provided with for spacing mould bases 19 at the baffle plate 12 of mould bases guide rail 2 upper extreme position.In mechanism, when mould bases 19 along mould bases guide rail 2 on mold-change trolley mobile contact to edge with baffle plate 12 time, limited post 8 is risen by cylinder to be fixed mould bases 19, mould bases vibration when preventing moving of car.For the spacing mould bases 19 position on mold-change trolley from the left and right sides further, the vehicle frame outside mould bases guide rail 2 is additionally provided with the liftable limiting plate 4 from the spacing mould bases in the mould bases left and right sides 19, bottom limiting plate 4, controls lifting by vertically disposed cylinder.
For making the road wheel 19A of mould bases import on mould bases guide rail 2 smoothly and accurately, mould bases 19 is drawn in be respectively equipped with outside the mould bases guide rail 2 of mold-change trolley upstream end and is guided, with mould bases 19 lateral wall, the directive wheel 20 coordinated.
For ease of regulation mould bases height on mold-change trolley, such as Fig. 4, shown in Fig. 5 and Fig. 6, mould bases elevating mechanism is all around correspondingly provided with four groups along mould bases guide rail 2 direction, both sides, and the position of four assembly mould frame elevating mechanisms is just corresponding with the road wheel 19A bottom mould bases, the position that mould bases guide rail 2 is corresponding with mould bases elevating mechanism is provided with disconnection section, mould bases elevating mechanism includes that the disconnection section with mould bases guide rail 2 carves the lifting platform 5 of conjunction, lifting fluid cylinder it is provided with bottom lifting platform 5, such as Fig. 5, when lifting platform 5 by lifting fluid cylinder jack-up time just concordant with mould bases guide rail 2 so that mould bases 19 moves along mould bases guide rail 2, when lifting platform declines, such as Fig. 6, mould bases 19 declines with lifting platform 5 makes mould bases baseplane just contact so that mould bases 19 is laterally out of mold-change trolley with the bearing roller 3 on vehicle frame.In the mould bases elevating mechanism of the present invention, under normal circumstances, lifting fluid cylinder is by the most concordant with mould bases guide rail 2 for lifting platform 5 jack-up, the road wheel 19A of mould bases can be normal through the mould bases guide rail 2 before and after road wheel, when four road wheel 19A of mould bases are exactly on lifting platform 5, the height of lifting platform 5 can be regulated thus the height of adjusted in concert mould bases 19 by lifting fluid cylinder, when reducing lifting platform 5, making mould bases 19 base plane just contact with bearing roller 3, from laterally mould bases being moved mold-change trolley removal or can move into.
The forcing press quick die change dolly of the present invention, it is possible to achieve quickly by large-scale mould bases into and out press bench.For ease of movement and the transport of mould bases 19, the bottom of mould bases 19 is furnished with the road wheel 19A supporting with mould bases guide rail 2.In using, mould bases 19 pulling by mould bases push-pull mechanism to be removed on press bench, mold-change trolley is moved into along mould bases guide rail 2 through the guide effect of directive wheel 20, now, the lifting platform 5 of mould bases elevating mechanism is the most concordant with mould bases guide rail, the road wheel 19A making mould bases can roll smoothly on mould bases guide rail 2, when four road wheel 19A walk to just above lifting platform 5, just contact with baffle plate 12 on front side of mould bases, limited post 8 and the limiting plate 4 of mould bases detent mechanism rise, and are firmly secured on mold-change trolley by mould bases 19；Then moving of car is driven to transport mould bases to mold frame library by trolley driving mechanism；When arrival mold frame library needs to remove mould bases from dolly, reduce the height of lifting platform 5, mould bases whole height decreases, make mould bases bottom surface contact with bearing roller 3 and pass through bearing roller 3 to support the overall weight of mould bases, now from mould bases 19 laterally can rely on from mold-change trolley the rolling of bearing roller 3 pull out, put back to the appointment position of mold frame library.Otherwise, the process that mould bases delivers to press bench from mold frame library is also suitable.Therefore, by the forcing press quick die change dolly of the present invention, it is possible to achieve moved into from press bench by Large heavy mould bases, mobile and transport, and it is substantially reduced the labor intensity of operator, improves die change work efficiency, reduce die change downtime.
