As shown in figure 11, the exhaust passage includes left side oil guiding hole 235 and hold-down bolt hole 236, the hold-down bolt Hole 236, left side oil guiding hole 235 and closed cavity 212 are sequentially communicated, and the aperture in the hold-down bolt hole 236 is more than the left side The aperture of oil guiding hole 235, it is excessive that hold-down bolt hole 236 and 235 junction of left side oil guiding hole are equipped with converging transition, hold-down bolt hole 236 sides are equipped with gas vent 231, and the gas vent 231 is connected with 236 bottom of hold-down bolt hole, and the aperture of gas vent 231 is 2mm。

During to closed 212 internal-filling liquid pressure oil of cavity, hydraulic oil passes sequentially through pressure regulating bolt hole 234, sealing piston hole 233 and right side oil guiding hole 232 after enter the closed cavity 212, the air in closed cavity 212 is gradually caught up with to exhaust passage Inlet side, the air in closed cavity 212 pass through left side oil guiding hole 235 and enter hold-down bolt hole 236, and then a part enters 231 mouthfuls of the gas vent of 236 bottom of hold-down bolt hole, is discharged from gas vent 231, and another part is from hold-down bolt hole 236 with compressing The fit clearance discharge of bolt 210.Exhaust outlet 231 is set up to avoid because hold-down bolt hole 236 and hold-down bolt 210 coordinate tension And the air in closed cavity 212 is caused to arrange situation about not going out, while increase oil-filled exhaust efficiency.

Embodiment 13

A kind of lithium battery electrode plate cutting device of the present embodiment, on the basis of embodiment 12, different and improvements It is：As shown in Figure 10, the pressure-regulating device includes sealing promotion plug 26, air-tight movable core 27 and pressure regulating bolt 28, the sealing promotion plug 26 and the air-tight movable core 27 are inserted successively in the sealing piston hole 233, and the sealing pushes away It is made, such as nitrile rubber of the preferable elastic material of sealing performance into plug 26, sealing promotion plug 26 and 233 mistake of sealing piston hole It is full of cooperation, to ensure to have preferable sealing effect, the diameter of sealing promotion plug 26 is more than the aperture of the right side oil guiding hole 232, Sealing promotion plug 26 is avoided to enter closed cavity 212 by right side oil guiding hole 232,26 head of sealing promotion plug is taper, is sealed 26 head taper surface of promotion plug and the taper surface of the converging transition of 232 junction of sealing piston hole 233 and right side oil guiding hole coordinate, close Envelope effect is more preferable, and the air-tight movable core 27 is made of steel material, and the pressure regulating bolt 28 is M8 bolts, and pressure is adjusted Bolt 28 is screwed in the pressure regulating bolt hole 234 on the housing 23, pressure regulating bolt 28 and 23 connection side of housing Formula is is threadedly coupled.

As shown in Figure 10, the exhaust apparatus includes sealing ball 29 and hold-down bolt 210, the sealing ball 29 and pressure Tight bolt 210 is inserted successively in the hold-down bolt hole 236, and the ball 29 that seals is close for spherical steel ball or rubber bead Envelope ball 29 is located at 236 bottom of hold-down bolt hole, and the diameter of the sealing ball 29 is more than the left side oil guiding hole 235 and described The aperture of gas vent 231 avoids sealing ball 29 from entering closed cavity 212, the hold-down bolt by left side oil guiding hole 235 210 be M6 bolts, and hold-down bolt 210 is screwed in the hold-down bolt hole 236 on housing 23, the hold-down bolt 210 with it is described outer 23 connection modes are covered to be threadedly coupled.

Before closed 212 internal-filling liquid pressure oil of cavity, the hold-down bolt 210 keeps half to screw in state, and sealing ball 29 can It is rolled around in 236 bottom of hold-down bolt hole, sealing promotion plug 26, air-tight movable core 27 and pressure regulating bolt 28 are packed into and fill In oily channel.During filling liquid pressure oil, hydraulic oil passes sequentially through pressure regulating bolt hole 234, sealing piston hole 233 and right side oil guiding hole Enter the closed cavity 212 after 232, the air in closed cavity 212 is gradually caught up with to exhaust passage inlet side, hermetic type The opposite increase of air pressure in chamber 212, due to the effect of air pressure, oppresses steel ball toward 210 1 side roll of hold-down bolt, at this point, The aperture of the gas vent 231 of 236 bottom of hold-down bolt hole is connected with left side oil guiding hole 235, and the air in closed cavity 212 passes through Left side oil guiding hole 235 is discharged, while some air passes through hold-down bolt 210 and hold-down bolt hole after entering gas vent 231 Fit clearance exudation between 236, when the outer aperture of gas vent 231 and hold-down bolt hole 236 is slowly emerged hydraulic oil and no longer Intermittence emerge bubble when, can be considered that the hydraulic oil in closed cavity 212 has been filled with.Due between the cooperation of M6 bolts and bolt hole For gap generally within 0.5mm, the simple fit clearance exhaust velocity by bolt and bolt hole is slow, and easily blocks, and increases hole Diameter is exhaust velocity increase 2 times or more so that the Oil feeding process time greatly shortens, while reduces row after 2mm gas vents 231 The appearance of air-hole blockage situation.After hydraulic oil is full of, sealing promotion plug 26 and air-tight movable core 27 are inserted successively into oil-filled logical In road, then pressure regulating bolt 28 screwed in pressure regulating bolt hole 234, and ensure that pressure regulating bolt 28 is screwed in for part State, so that pressure regulating bolt 28 can be further threaded into when needing to supercharging in closed cavity 212, while by hold-down bolt 210 screw, and hold-down bolt 210 compresses sealing ball 29 so that the spherical surface of sealing ball 29 is pressed on hold-down bolt hole 236 and a left side On tapered face between side oil guiding hole 235, the connection between gas vent 231 and hold-down bolt hole 236 is blocked, it is fine so as to reach Sealing effect.

During long-time service, a small amount of air can be precipitated in hydraulic oil, and air is compressible fluid, when closed cavity 212 In there are during air, to pressurizeing in closed cavity 212, the air in closed cavity 212 can first be compressed, and cannot by be pressurized should Power is transferred directly on 21 inner wall of inner sleeve, and 21 inner wall deformation quantity of inner sleeve substantially reduces, so as to cause hydraulic locking tool apron without Vinculum iuris Tightly, the use of hydraulic locking tool apron is influenced, at this point, the exhaust port of hydraulic locking tool apron need to only be adjusted to hydraulic locking tool apron Being stood behind surface for a moment, makes the air accumulation in closed cavity 212 that hold-down bolt 210 then be screwed out one to exhaust port Part makes sealing ball 29 that can be rolled around in 236 bottom of hold-down bolt hole, so as to make gas vent 231 and left side oil guiding hole 235 Connection, then screws in a part, oppressing the air in closed cavity 212 makes it from 231 row of gas vent by pressure regulating bolt 28 Go out, when gas vent 231 is not when there is bubble to emerge, tighten hold-down bolt 210.In this way can to avoid for a long time use rear liquid Pressure locking tool apron coupling mechanism force declines, while hydraulic oil loss amount is less, does not need to supplement hydraulic oil again.
