On November 9, 2024, our company was awarded the patent for "Boosting Knife Cylinder"
2024-12-03
Shanghai, November 9, 2024- Shanghai Yangyu Hydraulic Technology Co., Ltd. (hereinafter referred to as "Yangyu Hydraulic") recently announced that the company has successfully obtained an important patent entitled "Pressurized Cutter Cylinder" granted by the China National Intellectual Property Administration, and the authorization announcement number is CN 221967457 U. The application date of this patent is February 2024, marking a new breakthrough in the company's innovation in the field of hydraulic technology. This utility model relates to the field of knife cutting cylinder technology. In order to solve the disadvantages of fast air pressure pushing speed, unstable knife cutting, and ineffective pressure boosting effect in the prior art, a pressurized knife cutting cylinder is proposed, which includes a first cylinder body and a second cylinder body. The second cylinder body is fixedly installed at the bottom of the first cylinder body and is connected to each other. The first cylinder body is equipped with a pneumatic piston rod that slides in the first cylinder body, and the second cylinder body is equipped with an hydraulic piston rod that slides in the second cylinder body. This utility model connects the first cylinder body and the second cylinder body, and a third cavity for hydraulic oil flow is provided between the pneumatic piston rod and the hydraulic piston rod. In the working state, high-pressure gas is controlled by an electromagnetic valve to enter the first gas cavity from the second gas hole through the first gas hole, and the pneumatic pressure is reduced. Transforming the propulsion into hydraulic propulsion makes the process of pushing the hydraulic piston rod smoother, At the same time, with the entry of high-pressure gas, the thrust on the hydraulic piston rod can be increased, and the equipment's pressurization effect is significant.
