Oil cylinder with reinforced piston and cooling function

Abstract

The invention discloses an oil cylinder with a reinforced piston and a cooling function, and relates to the field of oil cylinders. The oil cylinder comprises an oil cylinder body, a front end cover and a rear end cover are fixedly arranged on the two ends of the oil cylinder body respectively, the front end cover and the rear end cover are connected through reinforcing pipes, a water inlet is formed in the rear end cover, a water outlet is formed in the front end cover, the interiors of the reinforcing pipes are of cavity structures, the water inlet communicates with the water outlet through the reinforcing pipe, and sound absorption cotton is arranged in the middle of the rear end cover. According to the oil cylinder, four fixed columns on the outer side of a square oil cylinder are designed to be copper pipes, the interiors of the copper pipes are of cavity structures, the copper pipes are connected with the water inlet and the water outlet, the cooling effect can be improved on the basis of not changing the shapes and the functions of fixing supporting columns on the outer side of the oil cylinder without large changes, in the using process, only cooling liquid needs to be injected into a cavity through the water inlet, the reinforcing pipes made of copper pipes can absorb heat generated in the operation process of the oil cylinder, and therefore the temperature of the oil cylinder is prevented from being too high, and the heat exchange efficiency of the oil cylinder is improved.

Description

technical field [0001] The invention relates to the field of oil cylinders, in particular to a reinforced piston oil cylinder with a cooling function. Background technique [0002] Oil cylinder is the abbreviation of hydraulic oil cylinder. Specifically, it is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs reciprocating linear motion. It has a simple structure and reliable operation. When it is used to realize reciprocating motion, the deceleration device can be eliminated, and There is no transmission gap and the movement is stable, so it is widely used in various mechanical hydraulic systems. The output force of the hydraulic cylinder is proportional to the effective area of ​​the piston and the pressure difference on both sides; the hydraulic cylinder is basically composed of a cylinder barrel and a cylinder head, a piston and Composed of piston rod, sealing device, buffer device and exhaust device. Buffers and exhausts are applic...
