The rectangular block 22 passes through the rectangular frame 21.

[0023] In this technical solution, by rotating the lead screw 13 with opposite threads on the front and rear outer walls, two moving plates 12 can be moved in opposite directions, and the distance between the two moving plates 12 can be adjusted until each rectangular block 15 enters the corresponding rectangular frame 14, thus completing the installation of the mold 4 on the complex curved surface. By rotating the lead screw 20 with opposite threads on the front and rear outer walls, two moving plates 19 can be moved in opposite directions, and the distance between the two moving plates 19 can be adjusted until each rectangular block 22 enters the corresponding rectangular frame 21, thus completing the installation of the mold 5 on the complex curved surface. This increases the convenience of changing stamping dies and makes the use flexible and convenient.

[0024] In some technical solutions, such as Figure 1 , Figure 2 and Figure 5 As shown, two hydraulic cylinders 6 are fixedly installed on the top of the fixed plate 2. The output end of the hydraulic cylinder 6 passes through the fixed plate 2 and is fixedly installed on the top of the movable plate 3. Three electric cylinders 24 are fixedly installed on the upper side of the inside of the stamping operating table 1.

[0033] When in use, the universal wheels 10 facilitate the movement of the device.

[0034] Working principle: During installation, rotating the lead screw 13 with opposite threads on the front and rear outer walls adjusts the distance between the two moving plates 12 until each rectangular block 15 enters the corresponding rectangular frame 14, thus completing the installation of the complex curved surface lower mold 4. Rotating the lead screw 20 with opposite threads on the front and rear outer walls adjusts the distance between the two moving plates 19 until each rectangular block 22 enters the corresponding rectangular frame 21, thus completing the installation of the complex curved surface mold 5, increasing the convenience of changing stamping dies. During use, the part to be stamped is placed in the complex curved surface lower mold 4, and the hydraulic cylinder 6 drives the moving plate 3 and the complex curved surface mold 5 to move downwards, achieving rapid stamping. After stamping, the electric cylinder 24 drives the unloading shaft 25 to move upwards, so that the upper end of the unloading shaft 25 passes through the unloading hole 7, pushing out the stamped part and dropping it into the unloading hole 7, realizing the automatic unloading function and greatly increasing work efficiency.
