The current deformation form is mainly as shown in figure 1, the bending aluminum template 11 is provided with stress points at two ends, the middle part is extruded to generate bending deformation, and the shaping machine is used for shaping the form.
However, the current shaping machine has single form and function, and the same parameters for correcting the bending are uniformly used for correction. Some aluminum templates are not deformed by bending, and the same parameters are used for correction, so that the proper correction effect is not obtained.
The bending degree of the aluminum mould plates is different, some bending degrees are large, some bending degrees are smaller, and different correction parameters are adopted for different bending degrees.
The deformed form of the aluminum template is not limited to bending, and there is a small amount of distortion, such as the distorted aluminum template in fig. 2, in which the edges of both ends of the aluminum template are not on the same plane, and this form also requires different correction parameters.
There is also a small amount of local deformation of the aluminum form, such as the partially concave aluminum form 13 shown in fig. 3, with dimples 131 on the working surface, which form requires localized rolling flattening.
The automatic and intelligent shaping machine adopts different measures according to different deformation forms, however, the working plane of the aluminum template is also required to be measured in advance, deformation parameters are collected, deformation conditions are analyzed, and few people study the technology for collecting deformation data.
