Description
Technical Field
The invention relates to a hydraulic cylinder sleeve of a single-cylinder hydraulic cone crusher, which has good wear resistance, processability, dimensional stability, self-shock absorption and higher compressive strength, and also has good plasticity, toughness and hardness, and belongs to the field of manufacturing of special hydraulic cylinder sleeves.
Background
At present, in a single-cylinder hydraulic cone crusher, a hydraulic cylinder sleeve is made of steel. The defects are that: although the steel has high and uniform hardness and wear resistance, the steel sleeve has high manufacturing cost and high heat treatment process requirement, so the steel cannot play a role in self-shock absorption when being used for manufacturing the hydraulic cylinder sleeve of the single-cylinder cone crusher, the hydraulic cylinder sleeve is extremely easy to damage, and particularly for cone crushing with relatively large shock destructiveness, the steel hydraulic cylinder sleeve is extremely damaged.
Disclosure of Invention
The design purpose is as follows: the hydraulic cylinder sleeve of the single-cylinder hydraulic cone crusher, which has good wear resistance, hardness, shock absorption and higher compressive strength, and also has good plasticity and toughness, is designed to avoid the defects in the background art.
The design scheme is as follows: in order to achieve the above design objective. The invention is structurally designed: 1. the hydraulic cylinder sleeve adopts the design of casting and forming of spheroidal graphite cast iron, and is one of the technical characteristics of the invention. The purpose of this design is: the spheroidal graphite cast iron has carbon in spherical graphite form, mechanical performance far superior to that of grey iron and similar to that of steel, excellent casting, cutting and wear resistance, certain elasticity, high wear resistance, high lubricating performance, high shock absorbing performance, high cutting and high compression strength, low cost and convenient replacement. More important is: because the expansion coefficient of the spheroidal graphite cast iron is small, the phenomenon of the axle-locking cylinder cannot be caused. 2. The design of the upper oil passage through hole on the cylinder sleeve wall of the hydraulic cylinder sleeve and the lower oil passage at the lower part of the hydraulic cylinder sleeve is the second technical feature of the invention. The purpose of this design is: firstly, an oil drain hole is added on an upper oil way, so that the main shaft is prevented from exceeding the stroke in the ascending and descending process; secondly, the O seal is added to the lower oil groove (because the working pressure is 2MPa-3 MPa), so that the hydraulic cylinder can be normally sealed, leakage cannot be caused, and an exhaust hole (air has compressibility) is added to the lower part, so that the discharge port of the single-cylinder hydraulic crusher cannot be changed due to air, and the operating condition using requirement is met.
The technical scheme is as follows: the hydraulic cylinder sleeve of the single-cylinder hydraulic cone crusher adopts spheroidal graphite cast iron, the upper part of the hydraulic cylinder sleeve is provided with a concave forming step, the cylinder sleeve wall at the upper part of the concave forming step is provided with an upper oil way through hole, and the lower part of the hydraulic cylinder sleeve is provided with a sealing groove and a lower oil way channel.
Compared with the background technology, the invention not only realizes the purpose of self-lubrication of the hydraulic cylinder sleeve, but also plays the role of self-shock absorption, avoids the generation of the cylinder holding phenomenon, and ensures the normal operation of the single-cylinder hydraulic cone crusher; and secondly, the processing cost is low, the replacement is easy, and unexpected economic and social benefits are obtained.
