[0030] The following is combined with Figure 1 This application is described in further detail.

[0031] This embodiment discloses a shearing machine for processing metal sheets, comprising a frame 1, a blade 2, and a driving mechanism consisting of a drive rod 3, a counterweight frame 4, and a drive cylinder 5. The frame 1 serves as the supporting structure of the entire shearing machine, providing a stable cutting platform. The blade 2 is used to directly cut metal sheets, one end of which is rotatably connected to the frame 1, and the other end is connected to the counterweight frame 4 through the drive rod 3. The counterweight frame 4 is uniquely designed, with one side being rotatably connected to the frame 1 and the other side being suspended and connected to the output end of the drive cylinder. The drive cylinder is rotatably connected to the frame 1, and drives the counterweight frame 4 and the drive rod 3 through a telescopic action, thereby driving the blade 2 for cutting.

[0032] Thus, the user controls the movement of the drive cylinder to rotate the counterweight frame 4, which in turn drives the blade 2 to cut via the drive rod 3. Due to the use of the lever principle and the presence of the counterweight frame 4, it can provide a certain amount of auxiliary force for cutting metal sheets, effectively reducing the load on the drive cylinder during cutting, thereby reducing the overall power consumption and cost of the equipment.

[0033] A workbench 11 is mounted on the frame 1, along with a cutting groove, where the blade 2 is positioned. This design provides better support and stability for the metal sheet during cutting, further improving cutting accuracy. Furthermore, the drive cylinder and counterweight frame 4 are located below the workbench 11, making the entire device more compact and conserving space.

[0034] A material positioning plate 12 is added to the workbench 11, and the positioning plate 12 can be slidably arranged on the workbench 11. By adjusting the position of the positioning plate 12, the user can conveniently fix and position metal sheets of different sizes, thereby improving the versatility and ease of use of the equipment.

[0035] A guide frame 13 is added to the frame 1, which is provided with a guide slot. The blade 2 is equipped with a guide rod 21 that cooperates with the guide slot. This design enhances cutting accuracy and stability. During the cutting process, the guide rod 21 moves along the guide slot, ensuring the stability and precision of the blade 2 during the cutting process.

[0036] The present embodiment further connects the driving rod 3 with the guide rod 21, thereby further enhancing the stability of the overall structure. Through this connection, the driving rod 3 can more directly and more accurately control the moving trajectory of the blade 2 during movement, thereby improving the precision of cutting.

[0037] A return spring 6 is added between the counterweight frame 4 and the frame 1. The two ends of the return spring 6 are connected to the frame 1 and the counterweight frame 4 respectively. When the driving cylinder drives the counterweight frame 4 to move, the return spring 6 can help the counterweight frame 4 to quickly return to its initial position, thereby improving the convenience and efficiency of the equipment.

[0038] The counterweight frame 4 has a first connection portion 41, a second connection portion 42, and a third connection portion 43. The first connection portion 41 is located at the edge of the counterweight frame 4 and is rotatably connected to the frame 1. The second connection portion 42 is used for rotatably connecting to the drive cylinder. The third connection portion 43 is located between the first and second connection portions 41, 42 and is rotatably connected to the drive rod 3. This design provides a more stable connection between the counterweight frame 4, the drive rod 3, and the blade 2, thereby improving the overall stability and service life of the equipment.

[0039] Furthermore, the shearing machine of the present embodiment is equipped with a pedal 7 for controlling the movement of the drive cylinder, and a pressure sensor is provided on the pedal 7. The user controls the movement of the drive cylinder by stepping on the pedal 7, thereby controlling the cutting force of the blade 2. The provision of the pressure sensor allows the user to precisely control the cutting force as needed, thereby improving the ease of operation and cutting accuracy of the device.

[0040] In addition, the shearing machine of the present application can not only be used to cut metal sheets, but can also be used to cut other materials as needed.

[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
