Aluminum profile as a lightweight, strong, corrosion-resistant materials, in all walks of life is widely used. With the development of social industrialization, it relies on its own unique characteristics, become indispensable to the development of industry "single profile", in order to meet the needs of different industries on the processing of aluminum profiles, industrial aluminum profile processing equipment came into being.
Common industrial aluminum profile processing equipment includes cutting machines, cutting saws, milling machines, stamping machines and so on. With high efficiency. They use advanced automation technology and precision machining technology to efficiently complete a variety of processing tasks. Cutting, milling, drilling, stamping and other functions can be carried out at the same time, which greatly improves the production efficiency. The efficient processing ability makes the aluminum profiles able to quickly meet the market demand, which promotes the development of the aluminum profile industry.
Industrial aluminum profile processing equipment common problem description:
1, cutting accuracy problems: industrial aluminum profiles in the cutting process, there may be cutting size precision is not high. If the cut is short, the splicing will appear in the gap is too large, affecting the beauty and load-bearing; if the cut is long, the aluminum profile frame can not be installed in place, the need for a second rework, affecting the construction period. Therefore, it is critical to control the cutting accuracy, the error is usually controlled within ± 0.5mm.
2, hole processing problems: processing holes, not only need to control the size of the hole, but also need to determine the location of the hole, depth and type, etc., so it is more complex than cutting. In the process of processing, the hole may be punched through the situation, resulting in the scrapping of the profile. In order to avoid this situation, it is necessary to draw processing drawings in advance, and accurate processing in accordance with the drawings.
3, surface cleaning problems: processing of aluminum chipping cleaning is not clean, will cause the appearance of the frame installation is not beautiful, and even lead to the profile end connection is not tight. Therefore, cleaning aluminum chipping is an important part of the process, need to pay enough attention.
4, improper control of extrusion temperature and speed: If the extrusion temperature is too low or the extrusion speed is too slow, the temperature of the extruder exit may not reach the solid solution temperature, can not play the role of solid solution strengthening. This will affect the performance and quality of the profile. The solution is to reasonably control the extrusion temperature and extrusion speed, to ensure that the extruder exit profile extrusion temperature remains above the low solid solution temperature.
5, insufficient cooling conditions: If the number of industrial aluminum alloy profile outlet fan is insufficient or the air volume is insufficient, it will lead to slow cooling. The inability to reduce to below 200°C in a short period of time may lead to premature precipitation of magnesium bisilicate, thus reducing the phase and mechanical properties of the solid solution. The solution is to strengthen the air cooling conditions, if necessary, can be added to the atomized cooling device.
6, mold manufacturing problems: in the mold manufacturing process, may be found on the final polished surface with sand holes or do not know m miscellaneous particles. This may be due to material or process problems. In order to solve this problem, the need to strengthen the mold manufacturing process of quality control and testing.
7, improper aging process: improper aging process, poor hot air circulation or thermocouple installation position is not correct, may lead to insufficient or excessive aging. This will affect the performance and service life of the product. The solution is to reasonably determine the aging process, the correct installation of thermocouples and ensure that the hot air circulation is smooth.
8, ingot composition and homogenization problems: ingot magnesium, silicon content does not meet the standard requirements or ingot inhomogenization, will affect the performance and quality of the product. The solution is to strengthen the ingot quality management and ingot homogenization.
