Problems solved by technology
Among them, the manual method cannot meet the high-frequency and long-term working requirements, while the electric method will be limited by the working conditions, especially some devices work in the field without power supply
At the same time, with the cooperation of the electromagnetic reversing valve and the displacement sensor, when the purpose of controlling the reversing is achieved, the sensor is controlled by the proximity switch, so that not only the reversing is unstable and the reliability is poor, but also the control circuit part of the reversing device uses a circuit board Control, and the circuit board is a non-standard part, it is difficult to manufacture and process, and it is very difficult to repair after damage, and the maintenance cost is high
In addition, if the existing reversing device is continuously energized for a long time, it is easy to damage small devices and cannot meet the requirements of long-term energization, which also affects production efficiency to a certain extent

The invention belongs to the technical field of hydraulic cylinders. The invention discloses an automatic reversing hydraulic cylinder, which comprises a casing, a cylinder barrel and a piston. The casing is provided with a P port connected with an oil inlet pipe and a T1 port and a T2 port connected with an oil outlet pipe. The cylinder barrel is located in the casing Inside, the piston is located in the cylinder, and the piston can move back and forth axially under the action of high-pressure oil, and the cylinder can move back and forth axially relative to the housing under high-pressure oil, so that the two sides of the piston are respectively connected with the high-pressure oil. The hydraulic fluid is alternately connected to realize the reciprocating movement of the automatic reversing of the hydraulic cylinder. The hydraulic cylinder of the present invention can automatically reciprocate and move under the drive of hydraulic pressure. It is not only simple and compact in structure, low in manufacturing cost, and highly integrated, but also can save the use of reversing valves, without electric control, and avoids Unstable factors of electrical appliances, can work for a long time and have a long life.
Description
technical field [0001] The invention belongs to the technical field of hydraulic cylinders, in particular to an automatic reversing hydraulic cylinder. Background technique [0002] A hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear motion. Due to its simple structure and reliable operation, hydraulic cylinders are widely used in various mechanical hydraulic systems. Among them, in the actual work of the cutting sheet feeding mechanism of the automatic cutting machine, some automatic feeding devices and mineral processing machinery, it is often necessary for the hydraulic cylinder to continuously reciprocate continuously. [0003] At present, if the traditional hydraulic cylinder is to realize reciprocating motion, it needs to be controlled by an external manual or electric method with the help of a reversing valve. Among them, the manual method cannot meet the high-frequency and long-term working requirem...
