[0030] Reference Figure 4 And Figure 5 As shown in and, the lifting cutting mechanism includes a lifting plate 21, a second lifting cylinder 22, a connecting rod 23, a saw blade 24 and a driving motor 25;

[0031] One side of the lifting plate 21 is hinged to the support plate 12 inside the housing 11. The cylinder body of the second lifting cylinder 22 is installed on the support plate 12. The end of the lifting rod of the second lifting cylinder 22 is rotatably connected to the bottom surface of the lifting plate 21 through the connecting rod 23. That is, one end of the connecting rod 23 is rotatably connected to the end of the second lifting cylinder 22, and the other end of the connecting rod 23 is rotatably connected to the bottom surface of the lifting plate 21. In this way, the second lifting cylinder 22 can drive the lifting plate 21 to change its position. The rotating shaft 26 of the saw blade 24 is rotatably connected to the other side of the lifting plate 21. Under the drive of the drive motor 25, the saw blade 24 can rotate and cut along its own axis.

[0032] In one specific implementation, refer to Figure 5 The saw blade 24 is fixedly connected to one end of the rotating shaft 26. The rotating shaft 26 of the saw blade 24 is mounted on the lifting plate 21 via a bearing sleeve 27. A bearing is provided between the rotating shaft 26 of the saw blade 24 and the bearing sleeve 27, thereby enabling the saw blade 24 to rotate.

[0035] The working principle of the above-mentioned cutting device is as follows:

[0036] Depending on the size of the copper busbar and different cutting and processing requirements, the required mold 4 is changed (the main difference between different molds 4 is the size and shape of their positioning notch 401);

[0037] The corner of the copper busbar is pressed against the positioning notch 401 in the mold 4. The first lifting cylinder 3 drives the pressing component 2 to press down. The pressing strip 5 of the first horizontal part 201 of the pressing component 2 presses down the copper busbar and fixes the copper busbar on the cutting table 1.

[0038] The drive motor 25 drives the saw blade 24 to rotate. Under the push of the second lifting cylinder 22, one side of the lifting plate 21 is raised, so that the top of the saw blade 24 passes through the through hole 101 and the long strip gap 102 of the cutting table 1 to cut the corner of the copper busbar.
