High-speed punch hydraulic system connection method capable of realizing fast direction change

Abstract

The invention discloses a high-speed punch hydraulic system connection method capable of realizing fast direction change. Firstly, with a plunger pump in a hydraulic system as a center, a motor and an air filter are respectively arranged on both sides of the peripheral oil circuit of the plunger pump, and meanwhile, a pressure meter is mounted on each component; a valve subsystem which comprises an electromagnetic reversing valve, a check valve, an overflow valve, an energy accumulator and a proportional servo valve is arranged in the oil circuit area between a hydraulic cylinder and the plunger pump, wherein a filter and a cooler are sequentially mounted on the oil circuit between the energy accumulator and the plunger pump; the electromagnetic reversing valve and the check valve are connected in series in the valve subsystem to form a direction control loop, the overflow valve is connected in parallel with the direction control loop, and both ends of the proportional servo valve are directly connected into the peripheral oil circuit of the hydraulic cylinder. The high-speed punch hydraulic system connection method has the advantages that: the system can stably move, the speed of the system can be easily regulated, moreover, the travel of the system can be controlled, noise is reduced, the punching frequency is increased, and the service life is prolonged; meanwhile, the controllability of operation can be enhanced, and labor intensity can be decreased.

Description

technical field [0001] The invention relates to the technical field of hydraulic pressure, in particular to a connection method for a hydraulic system of a high-speed press that can realize quick reversing. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, and heat can be brought back to the oil tank. The hydraulic system device can generate more power than other devices. Under the same power, the hydraulic device is small in size, Light weight, high power density, compact structure. With the development of modern automobile industry, electronic technology and national defense industry, the market demand for stamping equipment, especially high-speed stamping equipment, is increasing. Stamping technology is one of the widely used metal pressure processing methods at present, so countries with advanced industries More and more stamping technology is used to replace cutting technology and othe...
