& nbsp; & nbsp; Longitudinal cutting line is a product that everyone is familiar with, but we are more concerned about how to grasp the future of this familiar product, because whoever masters the trend can win the market. Therefore, many companies now need to predict the future, of course, the accuracy is uncertain, but this judgment still needs to be made. Jinan Zeye will talk to you about the development of longitudinal cutting production line in the future, and what opportunities we can seize. I believe these issues are of great concern to everyone. Let's first take a look at the thickness of 0.3-3mm, width of 1850mm, and longitudinal cutting width of 30mm. The processing cost of the longitudinal cutting and slitting machine with no damage to the surface of the coil is higher, and it is also easier to recover the investment Now there is a pressure plate type There are several types of belt tension and roller tension Everything has evolved from several forms The biggest advantage of the pressure plate type is its low cost. When doing high-speed production line tension, it is easy to damage the board and may also cause high-temperature spontaneous combustion of the felt; Belt tensioning is not necessary for high-speed applications, as it results in high belt wear and high operating costs. Only materials with undamaged surfaces are willing to be used, and the manufacturing cost of belt tensioners is also high Nowadays, models that exceed 300M/MIN are mixed with roller tension and plate roller tension. Why is this the case?  & nbsp; & nbsp; Due to the roller tension, the surface roughness of the sheet can be reduced while obtaining tension So he is not limited by speed and will be the main direction for the development of longitudinal cutting and slitting machines in the future The roller tension station technology that can be used for multiple rewinding is a good technique to overcome this issue Due to its ability to reduce the surface roughness of the board and obtain tension So he is not limited by speed The roll type tension station for multiple rewinding is currently the latest technology, and no one has succeeded in it Nowadays, Taiwan machines are unable to produce them, only the roller tension slitting machines produced in Germany The situation where most of China's CNC machine tools rely on imports has not changed Wu Bailin said that although some domestic companies are able to produce certain products, their manufacturing capabilities are limited, and the use of imported CNC systems and functional components results in high product prices and a lack of competitiveness. Compared to the relatively high level of development in the field of whole machines, China's CNC systems and key functional components are relatively lagging behind. If these deep-seated technical problems are not solved, the cost and price of domestic CNC machine tools will not go down, and the accuracy, reliability and progressiveness technology of products will not go up.  & nbsp; & nbsp; With the acceleration of industrial upgrading, the demand for high-end CNC heavy-duty machine tools in the industry is quite urgent. Emerging industries such as nuclear power, wind power, large aircraft manufacturing, high-speed railways, etc. have high demands for specialized machines and complete processing equipment. High speed, high-precision, and multi axis composite processing requirements are put forward in special materials, ultra-thin parts, and irregular curved parts.  & nbsp; & nbsp; Zeye believes that in order for domestic production to take the lead, great efforts must be made in the roller tension station to reach the world's advanced level Based on the current situation, the main development direction for the future will be the production line with no damage to the surface of the coil and high-speed longitudinal cutting This series of longitudinal cutting lines is used to roll metal coils into coils of the desired width through unwinding, longitudinal cutting, and winding. If you want high speed, tension is a very important factor. Nowadays, the slitting machine has advanced to 800M/MIN, but the tension generating device needs to be matched. Maximum diameter of uncoiling and unwinding: Ф1500MM。 Nowadays, the cost of factory rent is getting higher and higher. In some parts of the Pearl River Delta, the monthly rent for factory buildings can reach 10-16 yuan/m2, and there is a trend of increasing rent every year. Scope of application of slitting machine: Cold rolled steel coils, stainless steel, color coated coils, and tinplate slitting production lines.
