Description

Extrusion die for one solar frame and two solar frames

Technical Field

The utility model relates to the technical field of aluminum profile extrusion dies, in particular to a solar frame one-out-two extrusion die.

Background

As shown in fig. 1, the solar frame has high requirements for straightness and appearance, has a relatively small cross section, and is easily deformed when stretched. Therefore, the mold design requirement of the solar frame is high. In practical production, two common problems may occur in the extrusion process of the solar frame: the thickness does not reach the standard and the closing phenomenon. The problem of insufficient thickness is usually caused by deformation of the upper die of the die, and the thickness of the discharged material wall is asymmetric up and down and left and right. The pinching phenomenon is another common problem because solar rims typically have a long leg 1, which can lead to pinching during extrusion. The mould processing requirements of the solar frame are extremely high, and particularly no scratch exists near the working belt.

And, solar energy frame needs to be used in the open air, need carry out oxidation treatment after extruding, when solar energy frame needs to design a mould and go out the structure more, because follow-up oxidation production line needs parallel ejection of compact, consequently one go out two can not select the ejection of compact of upper and lower symmetry, we can only select bilateral symmetry ejection of compact in order to cooperate follow-up production line. Because of the lightweight nature of solar frames, large bars cannot be used, and thus counterbores are typically provided on the mold. However, the provision of the counterbore may cause problems including poor fluidity of the aluminum material, an increase in die pressure, an increase in discharge deformation, and a decrease in extrusion speed. Thus, improvements are needed.
