[0023] Embodiment 2:

[0024] Based on the above embodiment, this embodiment further defines the driving mechanism. The driving mechanism includes a first driving unit and a second driving unit. The first driving unit is connected to the support beam 4. The second driving unit is connected to the cutter head 5. Both the first driving unit and the second driving unit include two sets of driving components.

The driving components of the second driving unit are arranged on both sides of the cutter head 5 and are respectively connected to the support beam 4 and the cutter head 5. The driving component includes a lead screw 3 and a motor 6. There are fixing parts 21 at both ends of the support frame 2. First threaded holes are respectively arranged at the upper and lower ends of the support beam 4. The lead screws 3 at the upper and lower ends of the support beam 4 respectively pass through the first threaded holes of the support beam 4 and are connected to the fixing parts 21. The motor 6 is arranged on the side of the fixing part 21 and is connected to the lead screw 3. Connecting parts 41 are respectively arranged at both ends of the chute of the support beam 4. Second threaded holes are respectively arranged on the left and right sides of the cutter head 5. The lead screws 3 on the left and right sides of the cutter head 5 respectively pass through the second threaded holes of the cutter head 5 and are connected to the connecting parts 41. The motor 6 is arranged on the side of the connecting part 41 and is connected to the lead screw 3.

[0025] The driving mechanism of the first processing unit includes a first driving unit and a second driving unit. The first driving unit and the second driving unit each include two sets of driving components, and the driving components of the first driving unit are the same as those of the second driving unit. The driving component includes a lead screw 3 and a motor 6. First threaded holes are provided at both the upper and lower ends of the support beam 4. After the two lead screws 3 pass through the first threaded holes, they are connected to the end of the support frame 2. A fixing portion 21 is provided at the end of the support frame 2. One end of the lead screw 3 passes through the fixing portion 21 and is connected to the motor 6. The synchronous rotation of the motors 6 at both ends of the two lead screws 3 can drive the lead screws 3 to rotate, thereby driving the support beam 4 to move on the support frame 2. Similarly, second threaded holes are provided on both the left and right sides of the tool head 5. The two lead screws 3 respectively pass through the second threaded holes and are connected to the end of the support beam 4. A connecting portion 41 is provided at the end of the support beam 4.

Through the cooperation of the two sets of driving components of the first driving unit and the two sets of driving components of the second driving unit, the tool head 5 can be horizontally moved at any angle, so as to perform die-less incremental processing on the sheet metal 7.

[0026] When processing the sheet metal 7, the tool heads 5 on both sides of the sheet metal 7 gradually shape the sheet metal 7 in a way from shallow to deep. One tool head 5 on one side presses on the sheet metal 7, and the tool head 5 on the other side will limit the position of the sheet metal 7 being pressed to a certain extent. The two tool heads 5 cooperate with each other in motion. The tool heads 5 of the second processing unit and the tool heads 5 of the first processing unit cooperate with each other to respectively abut against the sheet metal 7, which can prevent the sheet metal 7 from being perforated, make the surface structure of the processed product uniform, and save the process of secondary polishing. Other parts of this embodiment are the same as those of the above embodiment, and will not be elaborated here.
