Description
One, affiliated field:
The present invention relates to fragmentation or shelling roll drawbench hydraulic mechanism or system's vibration damping machinery of oil plant strip plate in the oils preparation industry, particularly a kind of drawbench hydraulic cylinder piston rod mechanism vibration damping equipment.
Two, background technique:
At present, large-scale system oil enterprise is used for crushing roller or the employed hydraulic pressure drawbench of shelling roll wire drawing to be had multiplely, and using effect is different.Because large-scale crushing roller is very heavy, stock size weighs 1.8 tons at the crushing roller of Φ 400 * 2100, be 3 times of common weight, add drawbench lathe upper table (sliding table or be called slide unit), dividing head, about 1.6 tons of watt seat etc., total about 3.4 tons of weight that adds up to, the operating rate of worktable is respectively 7-11m/s, worktable comes and goes work, when the terminal point because the control valve snap back, worktable is moved immediately round about, formed very big impact force and vibration force, operation can only underspeed, generally reduce to about 5 meters, make that like this working efficiency of drawbench is very low, and the drawbench grinding roller is vertical with the grinding roller transmission device, the transmission effect of gearwheel is undesirable, structural design is unreasonable, therefore, impact force and vibration force are bigger, and reliable transmission is relatively low, therefore, be used for the hydraulic mechanism of fragmentation or the employed hydraulic pressure drawbench of shelling roll wire drawing or system's vibration damping at present and become the problem anxious to be solved of using of producing.
Three, summary of the invention:
The objective of the invention is: improve at the ubiquitous problem of prior art, design provides a kind of simple in structure, reliable transmission, good damping result, the relative less a kind of drawbench hydraulic cylinder piston rod with vibration force of impact force mechanism vibration damping equipment.
The technical solution adopted for the present invention to solve the technical problems is: a kind of drawbench hydraulic cylinder piston rod mechanism vibration damping equipment, comprise oil cylinder 3, piston 2 and piston rod 4 in the oil cylinder 3, bearing 7, hold-doun nut 10, it is characterized in that: between the outer end of piston rod 4 and bearing 7, vibration damping equipment is set, as shown in Figure 1.
Said vibration damping equipment is by preceding steel bushing 6, back steel bushing 9, the connecting rods 5 that are provided with in preceding steel bushing 6 and the back steel bushing 9, shock-absorbing spring 8 on the connecting rod 5, set screw nut 10 is formed, wherein, the T type that connecting rod 5 fell for level, one end is connected with the outer end of piston rod 4, the other end is fixed in the steel bushing 9 of back by set screw nut 10, and preceding steel bushing 6 is connected with bearing 7, and preceding steel bushing 6 and back steel bushing 9 are by being threaded, and in the preceding steel bushing 6 in the middle of the connecting rod 5 in preceding steel bushing 6 and the back steel bushing 9 and the space, both sides of bearing 7 shock-absorbing spring 8 is set respectively, as shown in Figure 1.
Be bearing 7 is clipped in the middle and tightens in the present technique with nut or nut with two shock-absorbing springs 8, make two shock-absorbing springs 8 be in the state of screwing, and keep certain elastic movement space, reverse impact is absorbed by shock-absorbing spring 8 when working like this, noise and Strike note reduce, moving speed of table can reach 6-7m/min, opening speed can reach 15-20m/min, increases work efficiency more than 30%, has solved the large hydraulic drawbench effectively because discaling roll weight is big, hydraulic shock is big, the difficult problem that drawing speed and opening speed are low, therefore, present technique has simple in structure, reliable transmission, the efficient height, good damping result, impact force is relative with vibration force less, rate of fault is low, characteristics such as long service life.
Four, description of drawings:
Fig. 1 is the schematic representation of general structure of the present invention.
Among the figure: steel bushings (front spring steel bushing), 7 bearings (piston rod bearing), 8 shock-absorbing springs, 9 back steel bushings (rear spring steel bushing), 10 set screw nuts (hold-doun nut) before 1 tightening nut, 2 pistons (oil cylinder piston), 3 oil cylinders, 4 piston rods (oil cylinder piston bar), 5 connecting rods (be connected and be fixed on the Spring steel shroud 9), 6 by set screw nut 10 with piston rod 4.
Five, embodiment:
The specific embodiment of the present invention, as shown in Figure 1, a kind of drawbench hydraulic cylinder piston rod mechanism vibration damping equipment, comprise oil cylinder 3, piston 2 and piston rod 4 in the oil cylinder 3, bearing 7, hold-doun nut 10 is characterized in that: between the outer end of piston rod 4 and bearing 7 vibration damping equipment is set, as shown in Figure 1.
Said vibration damping equipment is by preceding steel bushing 6, back steel bushing 9, the connecting rods 5 that are provided with in preceding steel bushing 6 and the back steel bushing 9, shock-absorbing spring 8 on the connecting rod 5, set screw nut 10 is formed, wherein, the T type that connecting rod 5 fell for level, one end is connected with the outer end of piston rod 4, the other end is fixed in the steel bushing 9 of back by set screw nut 10, and preceding steel bushing 6 is connected with bearing 7, and preceding steel bushing 6 and back steel bushing 9 are by being threaded, and in the preceding steel bushing 6 in the middle of the connecting rod 5 in preceding steel bushing 6 and the back steel bushing 9 and the space, both sides of bearing 7 shock-absorbing spring 8 is set respectively, as shown in Figure 1.
Be bearing 7 is clipped in the middle and tightens in the present technique with nut or nut with two shock-absorbing springs 8, make two shock-absorbing springs 8 be in the state of screwing, and keep certain elastic movement space, reverse impact is absorbed by shock-absorbing spring 8 when working like this, noise and Strike note reduce, moving speed of table can reach 6-7m/min, opening speed can reach 15-20m/min, increase work efficiency more than 30%, solved the large hydraulic drawbench effectively because discaling roll weight is big, hydraulic shock is big, the difficult problem that drawing speed and opening speed are low.
