How is the spiral steel pipe cut

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

First supply power to the control cabinet, and then turn off the automatic switch in the control cabinet. At the same time, the power switch of the console 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 outer position, and move the direction button to the directional position. Then press the stepper power start button and the saw blade motor starts the 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 running the equipment, check to ensure that the compressed air pressure remains at 0.6Mpa, and use the manual button to check whether the saw cylinder and brake cylinder can move. Before operation, use manual tools to put the flying saw trolley to the zero switch, and the trolley will automatically find 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 repeatedly. Then, press the stop button to stop the working program, let the flying saw trolley complete sawing the welded pipe, and then return to the zero position unchanged. If you want to change tools, even if the main menu appears on the computer display, press the keyboard's Reset key, then press the keys to select the tool and change the setup parameters.

It should be noted that if the spiral steel pipe unit needs to be shut down for a long time, the stepper power supply should be turned off first and the saw blade motor should be stopped to save energy. At the same time, the quality of the speed measurement photoelectric encoding working pulses 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 blade shape of the flat-end tool should be adjusted in time. The end face after the flat end of the steel pipe should be smooth and flat and meet the process requirements.
