Do you know how spiral steel pipes are sawed off? Are there any issues that need attention? Here is a brief introduction for everyone.

After a series of processes such as forming, welding, and cooling, spiral steel pipes still need to be sawed. In this link, the length of the technical spare ruler directly affects the quality and sales of the finished welded pipe, so the length of the spare ruler should be controlled between (+5 mm). In addition, in practice, employees must strictly abide by the following rules:

First, power the control cabinet, and then turn off the automatic switch in the control cabinet. At the same time, the power switch of the operating table is closed and the computer starts. Then, turn off the unloading start button, move the inner and outer control buttons of the uniform power cabinet to the external position, and move the direction button to the direction position. Then press the stepping power start button and the saw blade motor starts button to start working. At this time, the welded pipe sawing operation menu prompt appears on the computer display, and the staff can use manual, simulation, automatic, and setting tools according to the prompts.

Before the equipment is operated, it should be checked and confirmed that the compressed air pressure is maintained at 0.6Mpa, and the saw cylinder and brake cylinder can be checked with the manual button to see if they can move. Before the operation, use a manual tool to retract the flying saw trolley to the zero position switch, and the trolley automatically seeks zero. When the welded pipe head exceeds the speed measuring roller, the closed speed measuring roller can be made to work by pressing the button and pulse coding.

If you need to keep running automatically, you should press the start button on the keyboard, and the flying saw will run automatically and repeat. Then, press the stop key to stop the working program, so that the flying saw trolley can finish sawing the welded pipe, and then return to zero position and remain unchanged. If you want to change the tool, even if the main menu appears on the computer display, press the reset key of the keyboard, and then press the key to select the tool and change the setting parameters.

It should be noted that if the spiral steel pipe unit needs to be shut down for a long time, the stepping power supply should be turned off first, the saw blade motor should be stopped, and energy should be saved. At the same time, the quality of the speed-measuring photoelectric encoding working pulse should be checked regularly to prevent the encoder from being hit or immersed in water. According to the different specifications of the welded pipe, the position and edge shape of the flat-end tool should be adjusted in time. The end face of the steel pipe after the flat end should be smooth and flat, meeting the process requirements.
