Process design and key technology analysis of Photovoltaic aluminum alloy stamping part mold

In the process design stage of the Photovoltaic aluminum alloy stamping part, the quality of the shape of the process supplement surface directly determines the success or failure of the molding. When designing, it is necessary to ensure that the supplementary surface is smooth and smooth, and to add targeted features to eliminate molding risks such as wrinkles. At the same time, the setting of the draft angle should be in line with the material flow characteristics. In the flanging process, the amount of over flanging for Aluminum alloy water proof solar rail needs to be accurately matched based on the size of the rounded corner (R angle) of the product: generally, when the R angle is small, the amount of over flanging is correspondingly small, and when the R angle is large, the amount of over flanging needs to be appropriately increased to ensure the dimensional accuracy of the formed edge of the part.

Aluminum alloy materials have the characteristic of large rebound, and accurate rebound prediction is the core to ensure the dimensional accuracy of Photovoltaic aluminum alloy stamping part. By introducing sophisticated CAE analysis techniques, the entire process of parts can be simulated and analyzed for springback, and based on this, the mold surface can be compensated for springback, effectively offsetting the deformation caused by material elastic recovery. This compensation strategy based on simulation analysis can significantly reduce the on-site rectification and debugging cycle of Aluminum photovoltaic bracket accessories molds in the later stage, improve development efficiency and product quality stability.

The formability of aluminum plates is relatively poor, and higher requirements have been put forward for the design of the drawing die structure of Aluminum accessories for solar mounting. In the setting of the locator, it is necessary to combine the CAE analysis results, avoid the protruding areas of the material shrinkage line and the areas prone to wrinkling, ensure stable positioning and not damage the function of the drawstring, and avoid interfering with the flow of the sheet metal. At the same time, to ensure the stability of the Aluminum mounting brackets forming process, it is necessary to add anti lateral guide plates between the edge pressing ring and the upper mold to balance lateral forces. In addition, considering that the aluminum plate material is relatively soft and the mold has extremely high requirements for exhaust, the exhaust holes of the upper and convex molds need to be arranged reasonably to prevent stretching quality defects caused by poor exhaust.

Aluminum clamp hook for roof photovoltaic support is prone to generate a large amount of flying debris during the edge trimming process, which is a key and difficult point affecting the mold life and surface quality of the parts. For this reason, the trimming mold should adopt a design concept different from steel plate molds, such as using secondary cutting or floating knife methods to minimize the number of waste knives, and selecting high hardness inserts in high-yield situations to improve the smoothness of the cutting edge. In terms of design, the trimming blade block and the convex die edge can be designed with a negative angle structure to reduce friction and thus reduce debris generation from the source. At the same time, in response to the soft and easily deformed characteristics of the Aluminum solar panel end clamps for PV mounting system material, the convex mold needs to increase full surface support and strictly control the cutting amount of the trimming knife to ensure the quality of the trimming section.
