The invention belongs to an executing component in a hydraulic system and particularly discloses to a hydraulic cylinder with an automatic temperature reduction effect. The hydraulic cylinder comprises a cylinder body. The cylinder body is internally provided with a piston and a piston rod, and an upper oil inlet channel and a lower oil inlet channel are formed in the cylinder body; an outer cylinder is arranged outside the cylinder body, and a heat dissipation channel is arranged between the cylinder body and the outer cylinder; cavities are formed in the piston and the piston rod; a buffer is slidably connected into the cylinder body and internally provided with an oil cavity, and first springs are connected between the buffer plate and the cylinder body; a one-way air inlet valve and aone-way air exhaust valve are arranged on the lower portion of the cylinder body; a fixed rod is arranged at the bottom of the cylinder body, a partition plate is arranged on the fixed rod, and a water inlet pipe and a water drainage pipe are connected to the partition plate; a chamber is formed in the lower portion of the fixed rod, a through hole is formed in the fixed rod, a first magnet is arranged in the chamber, and a second magnet is arranged in the oil cavity; and a branch pipe communicating with the chamber is connected to the lower oil inlet channel. By using the hydraulic cylinder of the technical scheme, heat of the piston rod, the piston and the cylinder body can be taken away in the working process, and thus the temperature of the hydraulic cylinder is reduced.
Description
technical field [0001] The invention belongs to an actuator in a hydraulic system, in particular to a hydraulic cylinder with automatic cooling function. Background technique [0002] The hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swinging 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. , The movement is smooth, 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 a piston rod, a sealing device, a buffer device and an exhaust device. [0003] In some high-temperature environments and hydraulic syste...
