The specific embodiment
In Fig. 1, at first, give nitrogen that working cylinder backhaul chamber 22 pours certain pressure by pipe joint 18 or accumulator 20 is connected with working cylinder backhaul chamber 23 by pipe joint 18 with charger, piston rod will be return the work initial position under the high pressure nitrogen or the effect of accumulator hydraulic pressure; With flexible steel in flat section tubing 6 pipe joint on the driving cylinder cylinder body 35 is linked to each other with pipe joint 8 on the working cylinder cylinder body 13, charge into the hydraulic oil of certain pressure with oil-filled equipment by pipe joint 5, this moment, this Wedge mechanism was in the work original state.
After the work beginning, it is descending that the upper mould seat is pushed down actuation plunger 1, actuation plunger 1 compression hydraulic oil enters in the working cylinder operating room 22, promoting piston 11, piston rod 12 and die wedge mechanism 15 moves ahead, finish the function of mould process requirement, nitrogen during work in the piston 11 compression work cylinder the backhaul chamber 23 or hydraulic oil in the backhaul chamber 23 are pushed back in the accumulator, storage power use during for backhaul.The upper mould seat is up then, the pressure that acts on the actuation plunger is eliminated, under the effect of the interior hydraulic pressure of high pressure nitrogen in the working cylinder operating room 23 or accumulator, promote piston 11 and piston rod 12, drive 15 counter motions of die wedge mechanism to the original state of working, meanwhile, the hydraulic oil in the piston compression work cylinder working chambers 22 11 oppositely flows in the driving cylinder drive chamber 21, the promotion actuation plunger is up, finishes this Wedge mechanism backhaul action.
Its operation principle is as follows: when upper bolster was descending, it is descending that upper bolster is pushed down the plunger of driving cylinder downwards, the hydraulic oil in the compressible drive cylinder, and hydraulic oil flow into working cylinder through flexible steel in flat section tubing, promotes its piston motion, finishes the function action of mould demand; The nitrogen that piston compression backhaul meanwhile is indoor or compression hydraulic oil flows into accumulator, storage power use during for backhaul.When mould is up, the driving cylinder piston loses the pressure of upper bolster, working cylinder backhaul chamber high pressure nitrogen or the accumulator inner high voltage fluid cylinder piston reverses direction fortune merit (backhaul) that pushes the work forward, hydraulic chamber's hydraulic oil is back to driving cylinder, the up work initial position of getting back to of driving cylinder plunger under the effect of oil pressure is finished the backhaul action.
