Fig. 3 is a hydraulic schematic diagram of the present invention.
Fig. 4 is a fundamental diagram of the present invention.
Fig. 5 is that the D at A place among Fig. 4 is to view.
The specific embodiment:
Like Fig. 1; Fig. 4 and shown in Figure 5: automatic hoisting, rising and falling device for core roller of ring rolling machine comprises that base 2, connecting axle 3, lifting cylindrical shell 5, lifting beam 6, core roller 1, lift cylinder 4, slideway 9, rolling bearing 11, core roller locking cylinder 18, core roller move oil cylinder 22, master cylinder 19 and displacement transducer 20.One end of lift cylinder 4 is fixed on the base 2, and the other end is connected with lifting beam 6 through bearing pin 8.Promoting beam 6 connects as one through connecting bolt 7 and lifting cylindrical shell 5, core roller 1.Promoting cylindrical shell 5 is slidingly connected with slideway 9.Core roller 1 is fixing with connecting axle 3 through trip bolt 10.Rolling bearing 11 is in the connecting axle 3, be arranged on core roller 1 around.Displacement transducer 20 is housed on the lift cylinder 4, and displacement transducer 20 is connected with the controller of Ring Rolling Machine.Mandrel moves oil cylinder 22 and 1 vertical connection of core roller.Core roller locking cylinder 18 moves 22 vertical connections of oil cylinder with mandrel.
As shown in Figure 2: lift cylinder 4 comprises flange 12, cylinder head 13, piston rod 14, cylinder body 15, sealing ring 16 and piston 17.Flange 12 is fixed on cylinder head 13 in the cylinder body 13.Piston rod 14, sealing ring 16 is in the cylinder body 15 with piston 17.The end that piston 17 is in cylinder body 15 openings is connected through sealing ring 16 with piston rod 14.
As shown in Figure 3: the plunger shaft that gets into lift cylinder as hydraulic oil P through the check valve passage of NG30 adjustable pressure-reducing valve, NG22 3-position 4-way electro-hydraulic reversing valve, NG22 hydraulic lock, NG22 one-way throttle valve; Promote piston, piston rod is up; Drive core roller lifting device and mention, reach the purpose that the core roller promotes; The hydraulic oil of rod end chamber flows back to conduit under fluid pressure T through throttling passage, the 3-position 4-way electro-hydraulic reversing valve of NG22 one-way throttle valve.
Like Fig. 4 and shown in Figure 5: rise and fall because the core roller that will realize promotes automatically,, symmetrical two lift cylinders 4 must be set for core roller 1 is risen and fallen stably so what at first will gather is lift cylinder 4 and the position in the hoisting mechanism.Therefore on Ring Rolling Machine PLC programmable controller, increase counting module, increase the lifting control program, increased encoder collection position data and relevant auxiliary equipment.
Oil gets in the cylinder body 15 from the cylinder head 13 of lift cylinder 4; Promote piston 17; Piston 17 drives piston rod 14 and in lift cylinder 4, moves vertically upward, and piston rod 14 connects lifting beam 6 through bearing pin 8, under the control of electric control system; Two lift cylinders 4 are mentioned core roller 1 device along slideway 9 automatically rapidly, put into and take out for blank and shaping ring and leave sufficient space.After blank is put into workbench, under the control of electric control system, lift cylinder 4 oil-feeds; Promote piston 17 and drive piston rod 13; It is descending along slideway 9 that pulling promotes beam 6 drive core roller arrangements, and 1 in core is pierced in the blank hole, tightly pins mandrel 1 through mandrel locking cylinder 18 simultaneously.Moving the whole lifting device along continuous straight runs of oil cylinder 22 drives through mandrel moves.Through the work of master cylinder 3, make the ring blank carry out radial rolling simultaneously at king roller 7 and 1 of mandrel.For mandrel is rotated easily, fastening bolt 10 is integrated 3 of core roller 1 and connecting axles, and rolling bearing 11 is installed above that.
