Background

After being processed by a plurality of CNC procedures, the stress can be released inside the material after the injection molding of the aluminum extruded section/die-cast plate/NMT, so that the product is locally deformed. The shell of compact electronic equipment such as a mobile phone generally has higher precision requirement, so the shell needs to be shaped after being machined, thereby the qualification rate of products is improved, and the production cost is reduced. At present, manufacturers mostly adopt a shaping machine for pressing and shaping, for example, a shaping machine is disclosed in patent with application number CN202110592221.2 and name of shaping device, the shaping machine comprises a bearing support for placing materials to be shaped and a shaping mechanism for pre-pressing and shaping the materials to be shaped, the shaping mechanism comprises a shaping support, a pre-pressing assembly and a shaping assembly, the pre-pressing assembly comprises a pre-pressing plate driven by a pre-pressing driving module, a pre-pressing head is fixedly arranged on the pre-pressing plate, the shaping assembly comprises a shaping plate driven by a shaping driving module, and a shaping pressing head is fixedly arranged on the shaping plate, so that a plurality of positions of the materials to be shaped are pressed and shaped simultaneously. However, in the actual production process, since the material itself has a certain toughness, even if the material is subjected to heat treatment, the material will not keep the pressed shape after pressing, but will slightly rebound, so that the part to be shaped is usually required to be pressed with an overtravel, that is, the pressed distance exceeds the deformation distance thereof, in order to ensure the shaping effect. The shaping machine can only shape the material to be shaped in the deformation area, but in actual production, the deformation warping area is random, and if the undeformed area is pressed, the material can be damaged. Therefore, the existing manufacturer can correspondingly arrange one shaping machine according to the possible deformation area, for example, if the material to be shaped has three deformation areas, three shaping machines are prepared, the protruding distance of the pressure head of each shaping machine is adjusted, and the three shaping machines are used for independently pressing the three deformation areas. However, a large amount of production cost is consumed by the scheme, workers need to be correspondingly placed into different shaping machines according to detected deformation conditions, a large amount of labor and time are consumed, and production efficiency is reduced.
