[0031] In view of the technical problems described in the background art, as shown in the figure, a sheet metal 3D forming machine is provided, comprising: a frame 1, the frame 1 being used to install and support mechanical components, the frame 1 having a hollow area 2 for placing workpieces; a clamp 3, one or more clamps 3 being disposed around the hollow area 2, the clamps 3 being used to clamp and fix the workpieces; a moving platform 4, the moving platform 4 being disposed at the position of the hollow area 2; a first Z-axis moving module 5, the first Z-axis moving module 5 being connected to the moving platform 4, the first Z-axis moving module 5 being used to drive the moving platform 4 to move in the Z-axis direction; and an X-axis moving module 6, the X-axis moving module 6 being used to drive the moving platform 4 to move in the Z-axis direction. A moving module 6 is disposed on the hollowed-out area 2, and the X-axis moving module 6 is used to move along the X-axis direction; a Y-axis moving module 7 is mounted on the X-axis moving module 6 and is used to move along the Y-axis direction; a second Z-axis moving module 8 is mounted on the Y-axis moving module 7 and positioned above the hollowed-out area 2, and is used to move along the Z-axis direction; a pressure head mold 9 is mounted on the second Z-axis moving module 8 and is used to apply pressure to shape the workpiece; and a control system 10 is used to receive and output signals.

[0032] In the above technical solution, the control system 10 can be a numerical control system, which controls the operation of mechanical equipment by installing a program.

[0033] For the frame 1, a high-strength steel welded frame structure can be used to ensure overall rigidity and prevent deformation during processing. A hollow area 2 is set in the middle of the upper surface of the frame 1 to place the sheet metal workpiece (such as metal sheet) to be processed.

[0034] The clamps 3 are used to hold and fix the sheet metal. Optionally, there are four sets of clamps 3, which are respectively located at the four corners of the hollow area 2. The clamps 3 hold and fix the sheet metal at the four corners. Four sets of pneumatic / hydraulic clamps 3 can be used, located at the four corners of the hollow area 2, to hold and fix the four sides of the workpiece and prevent it from shifting during processing. The clamping force of the clamps 3 can be adjusted to accommodate sheet metal of different thicknesses.

[0035] The mobile platform 4 has 11 support plates. The mobile platform 4 is installed on the first Z-axis moving module 5 and is located below the hollow area 2. The mobile platform 4 moves in the Z-axis direction under the drive of the first Z-axis moving module 5.

[0036] The X-axis moving module 6 is installed on both sides of the hollow area 2. The X-axis moving module 6 is used to drive the Y-axis moving module 7 to move along the X-axis direction.

[0037] The Y-axis moving module 7 is mounted on the X-axis moving module 6. The pressure head mold 9 and the second Z-axis moving module 8 are both mounted on the Y-axis moving module 7. The Y-axis moving module 7 is used to drive the pressure head mold 9 and the second Z-axis moving module 8 to move in the Z-axis direction.

[0038] The second Z-axis moving module 8 is used to drive the pressure head mold 9 to move along the Z-axis direction, and apply pressure to the plate by the pressure head mold 9 to shape the plate.

[0039] The specific processing procedure is as follows: The four corners of the metal sheet are clamped by the clamps 3. The upper surface of the moving platform 4 supports the metal sheet. A relevant processing program is set in the control system 10, and the first Z-axis moving module 5 drives the moving platform 4 to descend gradually to a suitable height. Under the action of the second Z-axis moving module 8, the X-axis moving module 6, and the Y-axis moving module 7, the pressure head mold 9 is adjusted to the starting processing point. Layer-by-layer pressing: The second Z-axis module controls the pressure head mold 9 to press down, causing localized plastic deformation of the sheet material, which then moves along a preset path to gradually form the final product. After processing one layer, the first Z-axis moving module 5 drives the moving platform 4 to descend gradually, and by adjusting the Z-axis height, multi-layer progressive forming is achieved, ultimately forming a complex 3D curved surface.

[0040] By combining the linkage of the three-axis moving module with the pressure head mold 9, the sheet metal is shaped layer by layer. It can achieve the processing of irregular curved surfaces without the need for customized complex overall molds. It is especially suitable for the production of complex sheet metal parts with small batches and multiple varieties. It eliminates the need for molds and significantly reduces mold costs.

[0041] The "dual Z-axis collaborative system" design features a lower moving platform 4 that enables overall workpiece lifting and adjustment, allowing for adjustment of the overall longitudinal distance of the workpiece according to processing requirements. The upper Z-axis module controls the pressure head to precisely press the sheet metal in specific areas. Together, these two systems can complete complex forming processes such as deep drawing and multi-step forming.

The mobile platform 4 is used to support the processed workpiece. The pallet 11 and the upper and lower platforms 12 are detachable for easy replacement of the pallet 11. To improve the smoothness of the movement of the mobile platform 4, the slide plate 13 is connected to the side of the upper and lower platforms 12. The slide plate 13 cooperates with the first linear guide rail 14. When the mobile platform 4 is driven by the second Z-axis moving module 8, the movement is smoother with the cooperation of the first linear guide rail 14 and the slide plate 13.

[0050] The driving process is as follows: the third motor 31 drives the third reducer 32 to transmit power. The gear on the third reducer 32 meshes with the second rack 33. Since the second rack 33 is set parallel to the third linear guide 29, the slide 30 is installed on the third linear guide 29, thereby driving the slide 30 to move on the third linear guide 29.
