As shown in fig. 1 and 2, in the profile processing process, it is usually necessary to bend the edge of the profile to form a hidden fastening installation opening 122, and the width of the bent fastening installation opening 122 is sufficient for inserting a fastening element, for example, one side of the L-shaped aluminum alloy plate 123 is bent inward, and the edge of a designated position is usually extruded by using a hydraulic press or a punch press, however, in the prior art, the extrusion method is usually to extrude the edge of the profile toward the inner side of the profile (as indicated by the arrow F in fig. 2) from a punch in a direction perpendicular to the side wall of the profile, such extrusion easily causes the edge of the profile to tear to form a fracture, and the bent position forms a fastening installation sheet 124, since the mechanical structure of the fastening installation sheet 124 is a cantilever structure, the force strength is not high, and after being connected with other components by the fastening element, the fastening installation sheet is easily shaken.
As shown in fig. 3 to 17, in order to solve the technical problems in the prior art described above, in an embodiment of the present application, there is provided a hydraulic apparatus for reshaping an aluminum alloy, including a fixed bracket 101, a fixed die 102, a movable die 103, a first driving device 104;
the fixed die 102 and the movable die 103 are respectively connected with the fixed frame, and the movable die 103 is rotatably connected with the fixed bracket 101;
the first driving device 104 is connected to the fixed bracket 101 and the movable mold 103, respectively, and the first driving device 104 is adapted to drive the movable mold 103 to rotate relative to the fixed bracket 101;

when the movable die 103 rotates in one direction relative to the fixed bracket 101, the profiling extrusion surface 106 can be gradually inserted into an inward concave space surrounded by the profiling supporting surface 105;
after the profiling pressing surface 106 is inserted into the concave space formed by the profiling supporting surface 105, the profiling pressing surface 106 can be kept parallel to the profiling supporting surface 105.
