Hydraulic oil cylinder body and manufacturing method thereof

Abstract

The invention discloses a hydraulic oil cylinder body. The hydraulic oil cylinder body comprises a front end cover, a cylinder barrel and a dust remover, wherein the cylinder barrel is covered with the front end cover; the dust remover comprises an air outlet ring, a tubular air bag, a one-way air valve, a fixing ring, a dust removing ring and an opening and closing device; the air outlet ring comprises a ring body and a plurality of pressing type air valves; the pressing type air valves are uniformly distributed and mounted on the ring body in a circumferential direction; the pressing type air valves are communicated with the interior of the tubular air bag; the fixing ring is fixed on the front end cover; the one-way air valve is mounted on the tubular air bag; the opening and closing device comprises a plurality of abutting rods and a plurality of opening and closing rods; the middle parts of the opening and closing rods are rotatably mounted on the edge of the ring body and abut against the pressing type air valve in a one-to-one correspondence mode; and the plurality of abutting rods are fixed on the front end cover point to the ends, far away from the pressing type air valves, of the opening and closing rods in a one-to-one correspondence mode. The invention further discloses a manufacturing method of the hydraulic oil cylinder body. Compared with the prior art, the hydraulic oil cylinder body has excellent self-cleaning performance.

Description

technical field [0001] The invention relates to a manufacturing method, in particular to a hydraulic oil cylinder body and a manufacturing method thereof. Background technique [0002] As a commonly used hydraulic component, hydraulic cylinder has been endowed with more important significance in the rapid development of my country's industry today. Higher requirements are put forward for hydraulic cylinders in high-intensity working environments. Traditional hydraulic cylinders are used in During the telescopic process, the telescopic parts are exposed to the air, and when reciprocating, dust and other impurities are often brought into the cylinder, polluting the hydraulic cylinder, and greatly reducing the service life of the hydraulic cylinder. Therefore urgently need a kind of hydraulic oil cylinder with self-cleaning function to solve these problems. In view of this, the inventor of the present application obtained a hydraulic oil cylinder block and a manufacturing metho...
