What are the requirements for the power supply of the automatic fiber laser cutting machine
Automatic fiber laser cutting machine layout and cutting method in the machine layout: CNC flame cutting machine, cutting carbon steel with large thickness, low cutting cost, but there is large cutting deformation, cutting accuracy is not high, and The cutting rate is low, the cutting preheating time and the perforating time are long, and it is difficult to meet the needs of fully automated driving. Its application is limited to the cutting of carbon steel and large thickness plates. The cutting of medium and thin carbon steel plates will gradually be replaced by plasma cutting.
The plasma cutting of the automatic fiber laser cutting machine has a wide cutting platform, which can cut all metal plates, with a fast cutting speed and high compliance, and the cutting speed can reach more than 10m/min. Plasma cutting under water can eliminate the noise generated during cutting, dust, unprofitable gas and arc contamination, and effectively improve the situation of the workplace. Adopting sophisticated plasma cutting has brought the cutting quality closer to the level of laser cutting. At present, with the maturity of high-power plasma cutting technology, the cutting thickness has exceeded 150 mm, which has broadened the cutting limits of the automatic fiber laser cutting machine.
The desktop laser cutting machine is developed from the engraving machine, and the form is similar to the installation of a mini gantry cutting machine on the work table. This type of equipment has great advantages in the thin plate cutting platform and is widely used Used in the advertising and automotive sheet metal industries.
The portable cutting machine is developed from a semi-active trolley-type cutting machine. The trolley-type cutting machine is equipped with a numerical control system and transmission assembly. The basic form is similar to the trolley-type semi-active cutting machine. The type is cheap, the layout is light and convenient, and it is especially suitable for small and medium-sized plate processing. The cantilever CNC cutting machine is also an ancient classic machine layout. The single base is connected to the beam for first inspection, and the cutting gun moves laterally on the beam. This type of equipment is suitable for small and medium-sized plate processing. The CNC intersecting wire cutting machine is a special cutting machine. Its layout is very special, it is specially used for cutting pipes and cylindrical profiles. At present, there are not many domestic production plants and the demand is not large.
The CNC Cutting Machine (CNC Cutting Machine) uses a digital method to drive the action of the machine tool. When the machine moves, the cutting object is randomly equipped to cut the object. Such a mechatronics cutting machine is called a CNC cutting machine.
The one-sided operation data of the automatic fiber laser cutting machine system, the set life data and the processing method are generally stored in the RAM memory. After the system is powered off, it depends on the power supply The backup battery or lithium battery to connect. As a result, the shutdown time is relatively long, and plugging in or out of the power supply or memory may cause data loss, making the system unable to operate.
At the same time, because the automatic fiber laser cutting machine is equipped with a three-order exchange 380V power supply, the safety is also an important part of the early stage of the CNC equipment placement. For the above reasons, the automatic fiber laser The power supply used by the cutting machine has the following requirements:
1. The grid voltage fluctuation should be controlled between +10%-15%. However, the power supply in China has large fluctuations, poor quality, and high potential. Disturbances such as frequent pulses, plus salary components (such as sudden switch-off, etc.). In the electric mountain era, for example, during the day or about an hour before going to work, and at night, there are often more out-of-tolerances, even reaching ±20%. Make the automatic fiber laser cutting machine alarm and not be able to perform normal tasks, and cause damage to the power supply system of the machine tool. It even leads to the loss of relevant parameter data. This kind of symptom has been produced on machine tools such as plasma CNC cutting machines, and it is found to be more frequent, which should cause square attention.
Initiated the construction of an exchange voltage stabilized power supply system with active compensation and adjustment functions in workshops with dense automatic fiber laser cutting machine machine tools; a single CNC machine tool can be independently built with an exchange voltage stabilizer to handle it.
2. Initiated to continue the electrical equipment of the machine to a pure power source. If it is necessary to use the remaining power supply to supply power to certain parts of the electrical equipment (such as electronic circuits, electromagnetic concentrators), these power sources should be taken as much as possible from the devices (such as transformers, transducers, etc.) that constitute one part of the electrical equipment of the machine. For large and complex machines, including many machines that work together in a coordinated manner and occupy a large space, more than one attractive power source may be required, which depends on the construction of the field power source.
Unless the electrical equipment of the machine accepts the plug/socket and simply keeps the power supply, or the power cord is initiated and connected to the power terminal of the power cut switch. If this is not possible, a self-reliant terminal block should be constructed for the power cord.
The handle of the power cut-off switch should be easily approached, and should be placed between 0.6M and 1.9M above the easy-to-handle position. The upper limit was initiated at 1.7M. This can quickly cut off power in critical situations, reducing loss and staff casualties.
3, automatic fiber laser cutting machine machine tool requests for contraction atmosphere provision system CNC machine tools generally use a lot of pneumatic components, so the workshop should be connected to a clean and dry contraction atmosphere provision system webpage. Its flow and pressure should meet the requirements. The shrinking atmosphere is secretly placed in a place away from the machine tool of the fully automatic fiber laser cutting machine. According to the installation situation in the plant and the size of the space used, it should be considered to install the refrigerating atmosphere on the coal machine, atmosphere filter, gas storage tank, safety valve and other equipment for the shrinking atmosphere provider system.
