When it is used in the manufacturing of solar photovoltaic power generation aluminum extrusions, we should note

Solar energy is a new type of pollution-free green energy, is the focus of the development of one of the seven emerging industries, the pillar of its panels framework and its supporting structure, tie rod, supporting legs, etc. , can be made of the current economic durable aluminum alloy

solar energy is a new type of inexhaustible, inexhaustible pollution-free green energy, is China's determination to focus on the development of one of the seven emerging industries. The frame of panel and the pillar of support structure, tie rod, supporting legs, etc. In current economic durable aluminum alloy material. This is a new market of aluminum alloy material, has been in the global implementation and application. Aluminum extrusion die is to ensure that solar pv product shape and size precision of the important tools. Extrusion die design and manufacture of quality is to achieve high quality, high yield, low consumption, high efficiency, low cost the important guarantee of extruding production. Therefore, in order to produce high precision aluminum profile of photovoltaic (pv), it is necessary to optimize the design of the extrusion die and manufacturing. The use of advanced manufacturing equipment and high precision of extrusion die advanced extrusion mould processing equipment is the premise of guarantee the quality of metal extrusion dies. Aluminum profile for the production of photovoltaic, therefore, should use the advanced mold processing equipment, such as CNC, wire cutting, three axis machining centers and edm machining center, to improve the machining accuracy and performance of mould. Die opening the reasonable layout of photovoltaic aluminum in order to ensure the good symmetry, improve production efficiency and yield, the layout of the die must follow the principle of central symmetry, adopting multimode hole symmetrical layout. In the process of mold design, should as far as possible will bridge location on the profile of the decoration design, to avoid the flaws exposed. Extrusion die design work with the optimization of the work is stable with product size and ensure that the product surface quality of parts. When designing the length of the die working with, should as far as possible reduce the drop height, length change should be gradual. Block Angle and flow should be adopted to promote Angle to reduce the metal flow, in order to achieve the purpose of the metal flow uniformly, and improve the quality of the surface of the material. Materials used in the production of 6063 aluminum alloy chemical composition control, its chemical composition control are shown in table 1. Practice shows that 6063 aluminum alloy has become an important option for the production of high-precision aluminum profile photovoltaic. 6063 aluminum alloy belongs to aluminum magnesium silicon series reinforced aluminum alloy heat treatment. Alloy strengthening phase Mg2Si, good compression performance, quenching sensitivity low and high temperature plasticity is good, wide range of quenching temperature, the smaller critical quenching speed. In the national standard GB/T3190 provisions within the scope of 6063 aluminum alloy composition, the chemical composition of different value will lead to different material properties. When chemical composition range is larger, the performance difference will fluctuate on a wide range, makes it hard for the comprehensive performance of profile control. In order to ensure the accuracy of photovoltaic (pv) aluminum alloy profile, it is necessary to alloy chemical composition must be in strict accordance with the standards for controlling enterprises. Smelting, casting and ingot homogenizing process in 720 - smelting and refining process The rotation of the 760 ℃ of regenerative furnace smelting. 。 When the temperature higher than 720 ℃, to blow into the refining high purity nitrogen 15 minutes of a refining agent, refining agent dosage is 0, the weight of the melt. 08%, electromagnetic stirring to 15 minutes after refining, let stand 20 - aluminum liquid For 30 minutes. Sampling inspection strictly control the chemical composition of the aluminum alloy solution, cause the material to meet the requirements of mechanical properties.
