The common plate flange machine is a special equipment for forming the flange at the plate connection port of the air duct itself. The common plate flange system is one of the systems with a large amount of flange connections for air duct manufacturing in the world. It has the characteristics of convenience and is especially suitable for the production of air duct with a small cross-sectional area. The common plate flange system can be used for large-scale industrial production, and is a high-efficiency air duct flange system. It has good rigidity and stability, and the shape of motion molding is beautiful and flat. It can form a simple full-automatic air duct production line by combining with the reinforcement press, the plate shearer, the common plate flange folding machine, etc. The machine has a rigorous structure and good performance, which saves costs and reduces expenses for customers, and is a good choice for small production customers.

The operating procedures of the common plate flange machine can be divided into six movements: before starting, especially for the pump that has been stopped for a long time, the coupling must be rotated several times to ensure that the free rotation power of the rotating eye and the rotation direction of the inspection motor are consistent with the rotation direction of the scoop pump; Close the intermediate valve on the intake pipe; Start the motor; Open the 1N valve on the water supply pipeline, and the water supply will gradually increase until the water supply meets the specified requirements; When the pump reaches the limit of empty, open the word valve on the intake pipe, and the pump starts to work normally; Operation: it is better to adjust the packing gland so that the water droplets flow outward. If the slope material can ensure the required sealing due to wear of W44, it should be replaced with new material; The working temperature of the rolling sodium bearing shall not be higher than the ambient temperature by 35Y, but the measured temperature level shall be larger than 70 ℃; When used under the limit, the noise of the pump is large and easy to be damaged by cavitation, so as to reduce the noise. A small amount of gas enters the beam from the bleeder, and the common plate flange machine can take effect as long as the vacuum drops by about 250-350Pa; Stop: close the gate valve on the intake pipe; Close the inter-valve of the water supply pipeline; After the water is stopped, the repositioning pump will continue to run for 1-2 minutes, and the motor will be shut down after discharging part of the working fluid; If the parking space is more than one large, the plug at the bottom of the bundle must be opened and the water drained. The specific operating procedures are as follows:

1. The use of hydraulic device on flange rounding machine shall comply with the provisions of Section 3.1, Section 3.4, Section 3.8 and Appendix C of JGJ33-2001.

2. The strength and accuracy of the die on the flange rounding machine should meet the requirements, the edge should be sharpened, the installation should be stable, and the fastening should be reliable.

3. The drive part of the flange rounding machine shall be equipped with a protective cover. It is strictly prohibited to disassemble it during operation. The machinery shall be in the loader shed.

4. The specification of processing section steel shall not exceed the allowable range of machines and tools.

5. The machine shall be operated without load and can be operated only after it is confirmed to be normal.

6. When the rolled flange cannot enter the second profile roll, special tools shall be used for feeding. It is forbidden to push directly by hand.

7. When the diameter of the processed flange exceeds 1000mm, appropriate safety measures shall be taken.

8. No one shall be near the end of the flange.

9. During operation, non-operating and auxiliary personnel shall not stay around the machine to watch.

10. After operation, cut off the power supply, lock the switch box, and do a good job in daily maintenance.
