An oil discharge hole is arranged in the forging oil cylinder piston-piston rod.
Description
Technical field:
The present invention relates to a kind of mechanical-hydraulic multiplex control system that can realize to hydraulic precision forging machine high-frequency forging.
Background technology:
The high-frequency forging system of the forging oil cylinder of the hydraulic precision forging machine headed by making with Germany at present forges master cylinder by the hydraulic synchronization cylinder control of servo valve control to realize.But the action of servo valve can only be limited in 300-500 time/minute, so forging the rapidity of blow of oil cylinder also can only be at 300-500 time/minute, and hydraulic precision forging machine needs the speed more than 750-time/score in cold work made from shaping, so above-mentioned hydraulic precision forging machine can not carry out cold forging and trimming.
Summary of the invention:
Technical problem to be solved by this invention provide a kind of new, make hydraulic precision forging machine hit the frequency to reach 750 times/minutes above mechanical-hydraulic multiplex control systems.Make hydraulic precision forging machine can carry out cold forging and trimming.
Above-mentioned purpose is achieved in that it comprises the forging cylinder block, and depression bar is deceived axle, variable-speed motor, depression bar pressure strip, depression bar rising arm-tie, spring is fixedly connected with the depression bar pressure strip, forging on oil cylinder piston-piston rod has fuel outlet, depression bar with deceive axle and be rotationally connected.Eccentric shaft is fixedly connected with the axle of variable-speed motor, forges oil cylinder piston-piston rod and is contained in the forging cylinder block, and stifled plug cock is fixedly connected with depression bar.At the drain oil that forges the piston that oil cylinder piston-piston rod has the piston fuel outlet and be communicated with it-piston rod inside, tup is connected in the lower end of forging oil cylinder piston-piston rod, and hose coupling is connected drain oil in piston-piston rod and fuel tank by flexible pipe (not shown in FIG.).As being communicated with cylinder upper cavity oil to the working hole A that forges the three position four-way directional control valve of conveying high-pressure oil in the cylinder block, working hole B is communicated with oil cylinder backhaul chamber, and Motor Drive high-pressure oil pump, check valve are connected between overflow valve and the high-pressure oil pump..Advantage of the present invention is that the speed of variable-speed motor can reach more than 750 times/minutes the forging oil cylinder strike frequency 750-1500 rev/min of adjusting, and the practical experience card has reached 850 times/minutes.
Description of drawings:
Accompanying drawing is structural representation of the present invention.
The specific embodiment: describe structure of the present invention in detail below in conjunction with accompanying drawing.It comprises forges cylinder block 1, depression bar 2, and eccentric shaft 3, variable-speed motor 4, depression bar pressure strip 5, depression bar rising arm-tie 7, spring 6 are fixedly connected with depression bar pressure strip 5, and forging on oil cylinder piston-piston rod 9 has fuel outlet 8, depression bar 2 and deceive axle 3 and be rotationally connected.Eccentric shaft 3 is fixedly connected with the axle of variable-speed motor 4, forges oil cylinder piston-piston rod 9 and is contained in and forges that stifled plug cock 14 is fixedly connected with depression bar 2 in the cylinder block 1.At the drain oil 11 that forges the piston that oil cylinder piston-piston rod 9 has piston fuel outlet 8 and be communicated with it-piston rod inside, tup 12 is connected in the lower end of forging oil cylinder piston-piston rod 9, and hose coupling 13 has been connected connection to drain oil in piston-piston rod 11 with fuel tank 19 by flexible pipe (not shown in FIG.).Being communicated with working hole B with cylinder upper cavity oil 15 as the working hole A to the three position four-way directional control valve 21 that forges cylinder block 1 interior conveying high-pressure oil is communicated with oil cylinder backhaul chamber 10, motor 17 drives high-pressure oil pump 18, and check valve 16 is connected between overflow valve 20 and the high-pressure oil pump 18.
The course of work: connect motor 17 high-pressure oil pumps 18 and rotate the P mouth that hydraulic oil is delivered to three position four-way directional control valve 21 thereupon, connect variable-speed motor 4, deceiving axle 3 rotates thereupon and drives depression bar 2 and move up and down, make the electromagnet C2 energising of three position four-way directional control valve 21 when depression bar 2 descending same electric-control systems, hydraulic oil P enters in the cylinder upper cavity oil 15 by working hole A, when just passing through depression bar pressure strip 5 at descending depression bar 2, spring 6 and stifled plug cock 14 are blocked rear cylinder upper cavity oil 15 sealings to piston fuel outlet 8, pressure oil pressure rises to the highest and hits workpiece (not shown in FIG.) with its fixing tup 12 when promote forging oil cylinder piston-piston rod 9 and going downwards to lower initial point and continue to rotate because of variable-speed motor 4 this moment, depression bar 2 is become up and by depression bar rising arm-tie 7 stifled plug cock 14 is mentioned by descending, and the oil in the cylinder upper cavity oil 15 flow back to fuel tank 19 by the fuel outlet 8 of piston-piston rod and the piston that is communicated with it-piston rod inside drain oil 11 at once.Meanwhile, the electric-control system electromagnet C1 energising hydraulic oil P that makes three position four-way directional control valve 21 by working hole B enter forge make in the oil cylinder backhaul chamber 10 forging oil cylinder piston-piston rod 9 risen to in-situ accomplishes at once one hit circulation.
