[CN 201820954436.8] Hot Die Forging Press Brake Pneumatic System
[CN 201820954436.8] Hot Die Forging Press Brake Pneumatic System Title: Hot Die Forging Press Brake Pneumatic System Application Number: CN 201820954436.8 Applicant: Erzhong (Deyang) Heavy Equipment Co., Ltd. Application Date: 2018-6-20 Patent Type: Utility Model The utility model hot die forging press brake pneumatic system belongs to the field of braking technology and aims to improve the pressure relief rate of the brake cylinder. It includes a brake cylinder and a drive system; the drive system includes a gas path pipeline and an electromagnetic reversing valve arranged on the gas path pipeline; the gas path pipeline communicates with the brake cylinder; the drive system also includes a brake cylinder and an electromagnetic reversing valve The quick exhaust valve on a section of the gas path pipeline between the valves; the quick exhaust valve includes valve port 1., valve port two and valve port three; valve port one is connected with the gas path pipeline on one side of the quick exhaust valve, the valve port two is connected with the gas pipeline on the other side of the quick exhaust valve, and the valve port three is connected with the outside world. The valve core of the quick exhaust valve moves the connection passage between the valve port two and the valve port one or the valve port three. The pneumatic system of the hot die forging press brake avoids the exhaust pressure relief by electrical control by setting a quick exhaust valve, shortens the time consumed by electrical control, and improves the pressure relief rate of the brake cylinder.
