Solar energy frame aluminum alloy extrusion die

Abstract

The invention discloses a solar energy frame aluminum alloy extrusion die. The solar energy frame aluminum alloy extrusion die comprises an upper die and a lower die. The upper die comprises an upper die feed end and an upper die discharge end. The lower die comprises a lower die feed end matched with the upper die discharge end. The lower die feed end is provided with a first welding-combining chamber and a second welding-combining chamber in a concave mode. The center of the upper die feed end is provided with central flow dividing holes communicated with the first welding-combining chamber and the second welding-combining chamber. The upper die feed end is provided with two sets of flow dividing holes symmetrically formed with the upper die feed end as the center. Each set of flow dividing holes comprises first flow dividing holes, second flow dividing holes and third flow dividing holes. The first flow dividing holes and second flow dividing holes are oppositely formed, and the third flow dividing holes and the central flow dividing holes are oppositely formed. The first flow dividing holes, the second flow dividing holes and the third flow dividing holes of one set of flow dividing holes are all communicated with the first welding-combining chamber. The first flow dividing holes, the second flow dividing holes and the third flow dividing holes of the other set of flow dividing holes are all communicated with the second welding-combining chamber. Impact force generated by metal flow to the upper die during feeding is effectively balanced, so that the life of the solar energy frame aluminum alloy extrusion die is prolonged. In addition, double-hole extrusion production is achieved, so that the work efficiency is improved.

Description

technical field [0001] The invention relates to an extrusion die, in particular to an aluminum alloy extrusion die for a solar frame. Background technique [0002] Photovoltaic solar power generation, as a renewable and environmentally friendly energy source, has now ushered in the peak period of development driven by the international market and relevant domestic policies. my country has become the world's largest producer of solar cells / modules; and photovoltaic solar aluminum alloys Frame profiles occupy the position of the world's largest supplier. Due to the large batches of market demand, the current manufacturers of this type of material are all using small machines and single-hole extrusion. The disadvantage of this is that, on the one hand, in order to cope with large-volume production orders, many machines and molds are used, and the extrusion efficiency is low; on the other hand, the extrusion coefficient is low and the degree of deformation is insufficient when u...

AI Technical Summary

Problems solved by technology

The disadvantage of this is that, on the one hand, in order to cope with large-volume production orders, many machines and molds are used, and the extrusion efficiency is low; on the other hand, the extrusion coefficient is low and the degree of deformation is insufficient when using small machines , the mechanical properties that can be achieved are low, and the potential of extrusion deformation has not been fully utilized

Some manufacturers have also tried to use a large machine for production in order to obtain higher mechanical properties, but with single-hole extrusion production, the degree of deformation is too large, and it is easy to be unable to squeeze or even die prematurely.
