Damaged parts are replaced at a lowest cost by using the hydraulic nut, and the hydraulic nut is simple in operation, economical and practical.
Description
Technical field
The utility model relates to a kind of hydraulic nut, relates in particular to a kind of hydraulic nut that is used for the metal continuous extruder.
Background technique
The metal continuous extruder is a kind of employing vanguard technology, the metal continuous extrusion apparatus of being promoted rapidly at the metal manufacture field.It has characteristics such as manufacturing efficiency height, energy consumption are low, automaticity height.Hydraulic nut is a vitals in the metal principal axis system of continuous extrusion machine.The hydraulic nut parts that use on original metal continuous extruder, its Sealing is in time changed and when losing efficacy at work, cause the Sealing leakage of oil and high oil pressure is not beaten, cause hydraulic nut to dismantle, can only will can pull down after locking nut in the hydraulic nut parts or the retainer ring damage from main shaft.Hydraulic nut can't be reused, and causes greater loss.Summary of the invention
Loss was little when the purpose of this utility model was to provide a kind of dismounting, and hydraulic nut can the reusable hydraulic nut that is used for continuous extruder.
In order to achieve the above object, the technical solution of the utility model is: a kind of hydraulic nut that is used for continuous extruder, comprise withstanding tight block, pedestal and locking nut, form hydraulic pressure cavity between first end face of withstanding tight block and the pedestal, pedestal is provided with oil duct, locking nut has been threaded on the pedestal, second end face of locking nut and withstanding tight block offsets, be provided with first seal ring and second seal ring between described withstanding tight block and the pedestal, between second end face of described withstanding tight block and the locking nut pad is installed, second end face of locking nut and withstanding tight block offsets by pad.
Have the pad mounting groove between described withstanding tight block and the locking nut, pad is placed in the pad mounting groove.
Have V-type or U type groove on the described pad.
After adopting said structure, because second end face of locking nut and withstanding tight block offsets by pad.When hydraulic nut locking can't be unclamped, as long as V-type or U type groove along the pad of installing between second end face of withstanding tight block and the locking nut are severed it with cutting machine, discharge the pressure between locking nut and the retainer ring, just can unclamp locking nut, least disadvantage ground is changed and damaged parts, and is simple to operate and economical and practical.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the I portion enlarged view of Fig. 1.
Embodiment
The embodiment who provides below in conjunction with accompanying drawing is described in further detail the utility model.
As Fig. 1, shown in 2, a kind of hydraulic nut that is used for continuous extruder of the present utility model, comprise withstanding tight block 3, pedestal 2 and locking nut 1, form hydraulic pressure cavity B between first end face 3-1 of withstanding tight block 3 and the pedestal 2, pedestal 2 is provided with oil duct A, locking nut 1 has been threaded on the pedestal 2, locking nut 1 offsets with the second end face 3-2 of withstanding tight block 3, be provided with first seal ring 4 and second seal ring 5 between described withstanding tight block 3 and the pedestal 2, between second end face 3-2 of described withstanding tight block 3 and the locking nut 1 pad 6 is installed, locking nut 1 offsets by pad 6 with the second end face 3-2 of withstanding tight block 3.
As shown in Figure 2, have pad mounting groove 7 between described withstanding tight block 3 and the locking nut 1, pad 6 is placed in the pad mounting groove 7, is easy to like this install and use.
As shown in Figure 2, have V-type or U type groove on the described pad 6, convenient cutting.
The utility model is tightened with the outside thread of axle the internal thread of pedestal 2 earlier in use with manpower.Then the oil connection screw thread of pedestal 2 is connected with a ultrahigh-pressure hydraulic station with high-pressure oil pipe, with the hydraulic pressure cavity injection 200-300MPa high pressure oil of this oil pipe to 3 of pedestal 2 and withstanding tight blocks.This moment, withstanding tight block 3 was pushed to the direction of arrow indication by high pressure oil, formed the space at the C place, mating face of pad 6 and withstanding tight block 3, and manpower can be tightened locking nut 1 easily, and the elimination space compresses the parts on the main shaft.The pulling force that main shaft axially bears can reach hundreds of tons to thousands of ton forces according to varying in size of hydraulic pressure cavity sectional area.During the dismounting hydraulic nut, manpower can't be pulled down, to inject high pressure oil to the hydraulic pressure cavity place of 3 of pedestal 2 and withstanding tight blocks with the ultrahigh-pressure hydraulic station equally, make the pad 6 and the place, mating face of withstanding tight block 3 form the space once more, with manpower locking nut 1 backward rotation from the pedestal 2 is unclamped then, the hydraulic pressure cavity release, this moment, pedestal 2 can easily be pulled down from axle.
The main shaft operating temperature of metal continuous extruder is higher, and the Sealing in the hydraulic nut is aging easily under long term high temperature, needs in time to change.But following situation often takes place, and when promptly hydraulic nut installed on the main shaft, Sealing was good, can bear ultrahigh pressure.Through the long term high temperature baking, after the seal fails, in the time of need pulling down, the hydraulic pressure cavity place can't set up high oil pressure and promote withstanding tight block 3, and locking nut 1 can't unclamp from pedestal 2, and whole hydraulic nut can't be pulled down from main shaft.Can only will can pull down after locking nut 1 or withstanding tight block 3 damages.Hydraulic nut can't be reused, and causes bigger waste.
For the ease of the hydraulic nut after the dismounting seal fails, the utility model has increased a spacer elements 6 between locking nut 1 and withstanding tight block 3.Locking nut 1 offsets by pad 6 with the second end face 3-2 of withstanding tight block 3.The structure of this pad does not influence the function of use of hydraulic nut, when causing leakage of oil to dismantle, can it be cut, discharge the coupling mechanism force between locking nut 1 and the withstanding tight block 3 along the V-type groove of spacer elements 6 when seal fails, can unclamp locking nut 1, and hydraulic nut is pulled down from main shaft.After changing Sealing circle 4,5 and spacer elements 6, hydraulic nut is reusable.Changed the damage parts least disadvantage, simple to operate and economical and practical.
