With the more and more extensive application of aluminum profile, the processing requirements of aluminum profile are higher and higher. In order to meet the requirements of people like arc modeling and arc decoration on doors and windows, it is necessary to bend the profile into arc shape according to the specified radius of curvature and direction.

In the prior art, the arc bending methods for aluminum profile are pull bending and roll bending

Both methods require that the ratio (R / L) of arc radius (R) to the thickness (L) of profile along the radius direction (R / L) - generally not less than 20. When R / L is less than 20, deformation will occur, resulting in failure to meet the requirements. Moreover, the two arc bending methods have the common problems of poor dimensional consistency and low qualification rate.

Recently, with the progress of technology, microcomputer control technology is also used in stretch bending and roll bending equipment. Although the dimensional accuracy and qualification rate have been improved to a certain extent, the dimensional consistency still remains above the centimeter level, and the processing cost is relatively high.

When the design must require that the arc R / L of the profile is less than 20, in order to bend the profile into an arc shape, foreign countries have invented a method of tensile bending or roll bending after reinforcing the profile into a solid mandrel, as shown in Fig. 1a, FIG. 1b and Fig. 1C. P is the workpiece to be bent, f is the square tube of appropriate size, s is the low melting point filler metal (such as tin), and D is the direction to be bent. In this method, the profile P is first placed in the square tube F, then filled with low melting point filler metal s, bent along the D direction, and then heated to melt the metal s, so as to bend the profile P into a shape with R / L less than 20. Obviously, this method is very complex and the processing cost is very high.
