How the spiral steel pipe is sawn off

after a series of treatments such as forming, welding, and cooling, the spiral steel pipe still needs 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 within (+5 mm). also, in practice, employees must strictly observe 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 internal and external 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 start button to start working. at this time, the welded pipe sawing operation menu prompt appears on the computer screen, and the staff can use manual, analog, automatic, and setting tools according to the prompt.

before the equipment runs, check that the compressed air pressure is maintained at 0.6mpa, and use the manual button to check whether the saw cylinder and brake cylinder can move. before the operation, use a hand tool to retract 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 operated 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 run repeatedly. then, press the stop button to stop the work program, so that the flying saw trolley saw the pipe welding completed, and then return to the 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 button on the keyboard, and then press the button 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 should be turned off first, and the saw blade motor should be stopped to save energy. at the same time, the quality of the working pulse of the speed measuring photoelectric encoding should be checked regularly to prevent the encoder from being hit or immersed in water. according to the different specifications of the welded pipe, timely adjust the position and edge shape of the flat-end tool. the end surface after the flat end of the steel pipe should be smooth and flat and meet the process requirements.
