1、 Introduction to gas-liquid booster cylinder

The gas-liquid booster cylinder is an improved design that combines the advantages of both the cylinder and the oil cylinder. The hydraulic oil is strictly isolated from the compressed air, and the piston rod inside the cylinder automatically starts when it contacts the working part. The action speed is fast and more stable than pneumatic transmission. The cylinder body device is simple and the output adjustment is easy. Under the same conditions, it can achieve high output of the hydraulic press with low energy consumption. The soft landing does not damage the mold. It is easy to install and the special booster cylinder can be installed at any angle of 360 degrees. It occupies less space, has fewer faults and no temperature rise problems, has a long service life, low noise, and other core characteristics. The booster cylinder can achieve high output of the hydraulic cylinder using general air pressure without the need for a hydraulic unit. Boosting cylinders can generally be divided into: pre pressure boosting cylinders, direct pressure boosting cylinders, stroke adjustable boosting cylinders, increased return tension boosting cylinders, compact parallel boosting cylinders, mini boosting cylinders, fast boosting cylinders, and oil-gas isolation boosting cylinders.

2、 Characteristics of gas-liquid booster cylinder

1. Clever design, perfect and reasonable structure

2. Flexibly control the boost stroke according to the needs of different products; Fine and accurate

3. Suitable for metal stamping, forming, electronic component riveting, and extrusion molding, etc

4. Installation method: Upright (front axle with downward force)

5. This pressure boosting stroke can be adjusted, and the gas-liquid pressure boosting cylinder can accept customized special specifications

3、 Technical characteristics of gas-liquid booster cylinder

1. The maximum compressed air drive capacity is 6-8 kg, which can achieve a pressure of 1 ton to 200 tons without the need for a hydraulic system.

2. Three stage working process: a pneumatic fast forward stroke working cylinder, piston rod drive, force application part, fast and small force contact with workpiece - "soft in place" technology

3. The force stroke of the gas-liquid booster cylinder is at any position within the total stroke range. When the force applying part contacts the workpiece, it automatically starts the force stroke for full force stamping - the "power adaptive" pneumatic return stroke.

4. The automatic starting force stroke during the working process ensures that there is no impact vibration and extremely low noise, effectively improving the machining quality of the workpiece and the overall life of the force application part.

5. The control is simple and reliable, just like controlling a regular cylinder. It can be fully controlled by a two position five way valve, such as using a travel switch to control the force stroke and fast forward stroke, or using different pressures to control the force stroke.

6. The speed and force of the three-stage work stroke can be infinitely adjusted within the specified range and can be controlled by PLC.

7. The high boost ratio ensures that the gas-liquid booster cylinder has the smallest diameter and requires the least installation space among cylinders and hydraulic cylinders of the same tonnage.

8. Compared with cylinders, hydraulic systems, or other mechanisms of the same tonnage, it has extremely low energy consumption and high operating frequency. Some models can reach up to 125 beats per minute.

9. All imported high-quality sealing rings allow the use of non lubricated compressed air, and the clever design structure completely prevents compressed air from entering the oil chamber.

10. Each booster cylinder is equipped with a high-pressure measuring interface for the following operations: a. Connect a pressure gauge. b. Connect the pressure relay to set the boost pressure that is not affected by compressed air, and automatically return after reaching the preset pressure. c. Implement other functions required by users.

11. During maintenance and repair, the gas-liquid booster cylinder is extremely easy to replace, and high-quality imported seals have extremely low wear. If the seals are damaged, they can be replaced within one hour according to the assembly drawing.

12. The force stroke that starts only after the force part comes into contact with the workpiece can be used for various stamping processes such as precision pressing, punching, stretching forming, and press fitting.

4、 Principle of gas-liquid booster cylinder product

A booster cylinder is a hydraulic component that can convert input pressure and output it at a higher pressure. A booster cylinder is a combination of an oil pressure cylinder and a booster, which utilizes the ratio of the cross-sectional area of the pressurized area to the size of the booster. Since the pressure remains constant, when the pressurized area changes from large to small, the pressure will also change with different sizes, thus achieving the effect of increasing the air pressure by tens of times. Taking a pre pressure booster cylinder as an example: when the working air pressure is pressed on the surface of the hydraulic oil (or piston), the hydraulic oil will compress the air and flow towards the pre pressure stroke chamber. At this time, the hydraulic oil will quickly push the component to move. When the working displacement encounters resistance greater than the air pressure, the cylinder will stop moving. At this time, the boosting chamber of the booster cylinder will start boosting due to the action of the electrical signal (or pneumatic signal), thus achieving the desired pressure. The purpose of molded products.
