Description
Technical field
The utility model be related to it is a kind of both had good wearability, processability, dimensional stability, from absorb shock resistance and higher
Compression strength, there is good plasticity, toughness, the Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder of hardness again, belong to special liquid
Device for pressing cylinder liner manufactures field.
Background technology
At present in Single-Cylinder Hydraulic Cone Crusher, its hydraulic cylinder is made using steel.Its weak point：Although steel has
High and uniform hardness and wearability, but be due to the cost of manufacture height of steel bushing, Technology for Heating Processing requirement height, therefore it makes single
It can not play a part of during the hydraulic cylinder of cylinder gyratory crusher from shock absorbing, thus easily cause the damage of hydraulic cylinder, especially
It is that for vibration limitses are than larger cone crusher, the damage of its steel hydraulic cylinder is high.
Utility model content
Purpose of design：The weak point in background technology is avoided, design is a kind of both to have been had good wearability, hardness, disappeared
Pinking and higher compression strength, the Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder with good plasticity and toughness.
Design：In order to realize above-mentioned purpose of design.The utility model is in structure design：1st, hydraulic cylinder uses ball
The design of black iron casting shaping, is one of technical characteristic of the present utility model.The purpose so designed is：Spheroidal graphite cast-iron is
Carbon exists with the form of spherical graphite, and its mechanical performance outclass grey iron and close to steel, it has excellent casting, cutting
Processing and anti-wear performance, and with certain elasticity, thus it not only has good wearability, lubricity, absorb shock resistance, cutting
Processability and higher compression strength, and processing cost is low, changes convenient.More importantly：Due to the expansion of spheroidal graphite cast-iron
It is that number of poles is small, therefore does not result in the generation for seizing cylinder phenomenon.2nd, on hydraulic cylinder cylinder bore wall under upper oil circuit through hole, hydraulic cylinder
The design of subordinate's asphalt channel, is the two of technical characteristic of the present utility model.The purpose so designed is：One is top oil circuit
Increase oil leak hole, it is ensured that main shaft is in ascending and descending process without departing from stroke；Two be bottom oil groove increase O sealings（Due to work
Make pressure in 2MPa-3Mpa）, it is ensured that hydraulic cylinder can be sealed normally, not result in leakage, and increase a steam vent in bottom
(air has compressibility), it is ensured that single-cylinder hydraulic disintegrating machine discharge gate will not produce change due to air, and meeting operating mode makes
With requiring.
Technical scheme：A kind of Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder, hydraulic cylinder uses spheroidal graphite cast-iron and hydraulic cylinder
Set top is recessed step, and oil circuit through hole, hydraulic cylinder bottom shape are provided with the cylinder bore wall for being recessed step top
There are seal groove and lower asphalt channel.
The utility model is compared with background technology, and one is the purpose for both having realized hydraulic cylinder self-lubricating, is played again from shock absorbing
Effect, it is to avoid embrace the generation of cylinder phenomenon, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher；Two are machined to this
It is low, easily change, achieve unexpected economic benefit and social benefit.

Fig. 2 is the structural representation of hydraulic cylinder.
Fig. 3 is Fig. 2 side structure schematic view.
Embodiment
Embodiment 1：Referring to the drawings 1-3.A kind of Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder, hydraulic cylinder 1 uses spheroidal graphite
The cast iron and top of hydraulic cylinder 1 is recessed step 2, is provided with oil circuit through hole 3 on the cylinder bore wall for being recessed step top,
The bottom of hydraulic cylinder 1 has seal groove plus 4 and lower steam vent 5.Spheroidal graphite cast-iron is QT450-10.The inner wall surface of hydraulic cylinder 1 is coarse
Spend for Ra0.32-0.04 micron.
It is to be understood that：The detailed word although above-described embodiment is contrasted to mentality of designing of the present utility model
Description, but these word descriptions, simply to the simple text description of the utility model mentality of designing, rather than it is new to this practicality
The limitation of type mentality of designing, any combination, increase or modification without departing from the utility model mentality of designing each falls within this practicality new
In the protection domain of type.
