Abstract
The present invention relates to it is a kind of both had good wearability, processability, dimensional stability, from absorb shock resistance and higher compression strength, there is the Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder of good plasticity, toughness, hardness again, hydraulic cylinder is recessed step using spheroidal graphite cast-iron and hydraulic cylinder top, it is recessed on the cylinder bore wall on step top and is provided with oil circuit through-hole, hydraulic cylinder lower part shape has seal groove and lower asphalt channel.It the advantage is that：First, not only having realized the purpose of hydraulic cylinder self-lubricating, but also play the role of from shock absorbing, avoid the generation for embracing cylinder phenomenon, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher；Second is that processing cost is low, easily replaces, achieve unexpected economic benefit and social benefit.
Description
Technical field
The present invention relates to it is a kind of both had good wearability, processability, dimensional stability, from absorb shock resistance and higher anti-
Compressive Strength, and there is the Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder of good plasticity, toughness, hardness, belong to dedicated hydraulic cylinder
Cover manufacturing field.
Background technology
At present in Single-Cylinder Hydraulic Cone Crusher, hydraulic cylinder is made of steel.Its shortcoming：Although steel has
High and uniform hardness and wearability, but since the cost of manufacture of steel bushing is high, heat treatment process requirement is high, make single
It can not play the role of during the hydraulic cylinder of cylinder gyratory crusher from shock absorbing, thus easily cause the damage of hydraulic cylinder, especially
It is for the bigger cone crusher of vibration limits, the damage of steel hydraulic cylinder is high.
Invention content
Purpose of design：The shortcoming in background technology is avoided, design is a kind of both to have been had good wearability, hardness, disappeared
Pinking and higher compression strength, and the Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder with good plasticity and toughness.
Designing scheme：In order to realize above-mentioned purpose of design.The present invention is in structure design：1st, hydraulic cylinder is cast using spheroidal graphite
The molding design of iron casting is one of technical characteristic of the present invention.The purpose designed in this way is：Spheroidal graphite cast-iron is carbon with spherical shape
The form of graphite exists, and mechanical performance outclass grey iron close to steel, it has excellent casting, machining and resistance to
Grind performance, and with certain elasticity, thus it not only have good wearability, lubricity, absorb shock resistance, machinability and
Higher compression strength, and processing cost is low, and it is convenient to replace.More importantly：Since the expansion of spheroidal graphite cast-iron is that number of poles is small,
Therefore it will not cause to seize the generation of cylinder phenomenon.2nd, upper oil circuit through-hole on hydraulic cylinder cylinder bore wall, subordinate's oil circuit under hydraulic cylinder
The design of channel is the two of the technical characteristic of the present invention.The purpose designed in this way is：First, top oil circuit increases oil leak hole,
Ensure main shaft in ascending and descending process without departing from stroke；Second is that lower part oil groove increases O sealings（Since operating pressure exists
2MPa-3Mpa）, ensure that hydraulic cylinder can be sealed normally, will not cause to reveal, and increase a gas vent (air tool in lower part
Have compressibility), ensure that single-cylinder hydraulic crusher discharge gate will not generate variation due to air, meet operating mode requirement.
Technical solution：A kind of Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder, hydraulic cylinder use spheroidal graphite cast-iron and hydraulic cylinder
Set top is recessed step, is recessed on the cylinder bore wall on step top and is provided with oil circuit through-hole, hydraulic cylinder lower part shape
There are seal groove and lower asphalt channel.
The present invention is compared with background technology, first, not only having realized the purpose of hydraulic cylinder self-lubricating, but also plays the work from shock absorbing
With, avoid embrace cylinder phenomenon generation, it is ensured that the normal work of Single-Cylinder Hydraulic Cone Crusher；Second is that processing cost is low, easily
It replaces, achieves unexpected economic benefit and social benefit.

Specific embodiment
Embodiment 1：With reference to attached drawing 1-3.A kind of Single-Cylinder Hydraulic Cone Crusher hydraulic cylinder, hydraulic cylinder 1 use spheroidal graphite
Cast iron and 1 top of hydraulic cylinder is recessed step 2, is recessed on the cylinder bore wall on step top and is provided with oil circuit through-hole 3,
1 lower part of hydraulic cylinder has seal groove to add 4 and lower gas vent 5.Spheroidal graphite cast-iron is QT450-10.1 inner wall surface of hydraulic cylinder is coarse
It spends for Ra0.32-0.04 micron.
It is to be understood that：Although above-described embodiment contrasts to the mentality of designing of the present invention, detailed word is retouched
It states, but these word descriptions, only the simple text of mentality of designing of the present invention is described rather than to mentality of designing of the present invention
Limitation, any combination, increase or modification without departing from mentality of designing of the present invention each fallen in protection scope of the present invention.
