Do you know how the
spiral steel pipe is sawed 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 between (+5mm). 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 console power switch is closed and the computer starts. Then, close the unloading start button, move the inside and outside control buttons of the uniform power cabinet to the outside 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, a menu prompt for the sawing operation of the welded pipe will appear on the computer display screen, and the staff can use manual, simulation, automatic, and setting tools according to the prompt.
Before the equipment is in operation, check to make sure 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 manual tools to put the flying saw trolley back to the zero position 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 code.
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 key to stop the working procedure, so that the flying saw table car saws the welded pipe to complete, and then returns to the zero position and remains unchanged. If you want to change the tool, even if the main menu appears on the computer display, press the reset key on the keyboard, 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 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 working pulse of the speed-measuring photoelectric encoding should be checked regularly to prevent the encoder from being impacted or immersed in water. According to the different specifications of the welded pipe, adjust the position and edge shape of the flat-end cutter in time. After the flat end of the steel pipe, the end face should be smooth and flat, meeting the technological requirements.
