Usually the installation and maintenance of the plasma cutting machine are carried out by the technicians sent by the manufacturer, but we can also learn some basic installation and maintenance methods. If we encounter the need to move the work site, we can also install it ourselves! Here are some basic installation and debugging methods:
1. Installation of longitudinal rails
Longitudinal guide of gantry cutting machine needs to be installed on a solid base. We use H-shaped steel for the base. Because it is a large equipment, the general guide rail is placed on the ground. The ground is punched into the expansion wire to fix the horizontally adjusted guide rail firmly on the ground. The center distance of the two rows of longitudinal rails and the horizontal span must be the same. They can be measured diagonally. When installing, the center distance and level of the two rows of longitudinal rails must be ensured. During the actual installation, please follow the detailed drawings provided. Necessary adjustments have been made before the longitudinal rails leave the factory, so when installing the longitudinal rails, you only need to do the corresponding docking according to the marks on the rails.
2. Gap adjustment
The gap of plasma cutting machine includes guide gap and transmission gap. The gap of the equipment has been adjusted to the best before leaving the factory. Generally, it is not necessary to adjust the gap during the initial installation as long as the inspection is correct. But after using for a period of time, some gaps may need to be adjusted for some reasons.
3. Breathing tube
CNC flame cutting machine has oxygen or acetylene gas pipe. The joint at the joint is the same as the general hand torch joint, and the thread is M16 * 1.5. When the longitudinal cutting range is large, the air intake pipe and the power supply cable need to be pulled by an elevated way to make the air pipe and the cable at a certain height. The position moves back and forth.
To ensure the continuity of cutting, multiple bottles of oxygen and multiple bottles of acetylene should be connected in parallel respectively. To ensure safety, a tempering preventer should be connected to the low-pressure pipeline (outlet of pressure relief valve) of oxygen and acetylene gas.
4. Install the control cabinet
Install the control cabinet to the corresponding position and fix it with bolts.
5. Wiring
Connect the control cabinet with stepper motor, solenoid valve, etc., and connect the external AC 220V power cord. When the base frame is selected to be connected by several sections, the power cord and the air pipe are connected to the control cabinet via the drag groove beam.
6. Power on
Turn on the power switch and follow the normal operation sequence.
7. Self-check
Turn on the oxygen and acetylene gas, and start the cutting machine control program to carry out various work inspections. From the X and Y directions of the system and the ignition, etc., determine whether the system is working properly. Please note that when the trachea is just connected, there is air in the trachea, which can not ignite normally. You can use the "preheat" operation to drain the air in the tube first.
8. Header
The header usually has two methods, one is the square type and the other is the top type.
CNC plasma cutting machine checkered header is made of flat iron with a certain width (80-120) and thickness (5-8). The size of the grid can be determined according to the thickness of the commonly used blanking plate and the size of the parts, generally 100-150mm. The top type header is to fix the cone top made of cast iron to the channel steel at a certain distance (as shown in Figure 7-9 ) To form the top row of cones, and then arrange and fix multiple top rows of cones at a certain distance to form a header. This type of cutting table, because the cone top is cast iron, flame cutting is not easy to damage it, and it is easy to replace the damaged cone top individually (welding and fixing the screw on the channel steel, processing the threaded hole and lateral disassembly hole on the cone top, Easy to disassemble), so the use effect is far better than the former.
