Automatic fiber cutting machine is suitable for trimming of formed sheet metal parts
Taiwan group automatic fiber cutting machine is especially for steel plate with strength up to 1500MPa, because there is no other processing method to replace. In this case, users do not need to invest in expensive stamping equipment and cutting equipment. Because when processing these high-hardness materials, the service life of the die or tool of the traditional equipment will be greatly shortened, and laser cutting does not need to consider these issues, and it also has the advantages of short installation time, flexible product replacement or sample production. Three-dimensional platform group automatic fiber cutting machine is used in the cutting of car side walls, of course, including trimming. The B side wall is made of high-strength steel hot formed, which has high hardness and has to withstand great stress. The B side wall made of high-strength steel increases the impact resistance and improves the safety of the car. This is also the reason why automakers are willing to use high-strength steel despite its high cost. The traditional cutting process methods of Taiwan group automatic fiber cutting machine include flame cutting, plasma cutting, waterjet cutting, wire cutting and punch processing, etc. Laser cutting, as a new technology in recent years, is a laser beam with high energy density. It is irradiated on the workpiece to be processed to make the part heated and melted, and then the slag is blown off by high-pressure gas to form a slit. Laser cutting has the following advantages. The slit is narrow, the accuracy is high, and the slit roughness is good. After cutting, there is no need to reprocess the subsequent process. The laser processing system itself is a computer system, which can be conveniently arranged and modified, and is suitable for personalized processing, especially for some sheet metal parts with complex contours. There are many batches and small batches, and the product life cycle is not long. , Measured from the perspective of economic cost and time, manufacturing molds is not cost-effective, and laser cutting is particularly advantageous.
The laser processing energy density of the Taiwan group automatic fiber cutting machine is very large, the action time is short, the heat-affected zone is small, the thermal deformation is small, the thermal stress is small, and the laser is Non-mechanical contact processing, no mechanical stress on the workpiece, suitable for precision processing. The high energy density of the laser is enough to melt any metal, and it is especially suitable for processing some materials that are difficult to process with high hardness, high brittleness, and high melting point. The processing cost is low. The one-time investment in equipment is more expensive, but continuous and large-scale processing ultimately reduces the processing cost of each part. The laser is non-contact processing, with low inertia and high processing speed. The CAD/CAM software programming of the CNC system is time-saving and convenient, and the overall efficiency is high. The laser has a high degree of automation, can be completely enclosed for processing, has no pollution, and has low noise, which greatly improves the working environment of the operator. Some large-scale manufacturers have taken the lead in introducing advanced five-axis laser cutting machines from abroad, which greatly improved the process effect and increased production efficiency. Because five-axis machine tools are basically imported from abroad at present, the price is extremely expensive, and the equipment price of more than three to five million yuan is a threshold that is difficult to popularize for the majority of small and medium-sized manufacturers. Moreover, the current three to four million low-end five-axis laser cutting machines, the selected lasers are basically 2KW fast axial flow CO2 lasers, which need to be filled with He, Ne, CO2 and other gases, and the charge is 20 yuan/hour The power consumption of the system is about 30KW, plus the oxygen cost for auxiliary cutting and sporadic consumables, the accumulated hourly usage cost is as high as about 80 yuan.
