[0036] Preferably, the second driving device 1302 can be one of a gear and rack mechanism, a hydraulic cylinder, a linear cylinder and a linear motor.

[0037] Unstable movement of the material during processing may collide with other parts of the equipment, causing damage to the equipment. Therefore, in an embodiment, the clamping device 4 comprises a sliding seat 401 in sliding connection with the first sliding rail 101, a clamping assembly 402 arranged on the sliding seat 401 and a clamping driving part 403 arranged at the top of the clamping assembly 402, the clamping driving part 403 drives the clamping assembly 402 to rise and fall to clamp the material in the vertical direction.

[0038] In the embodiment, the clamping driving part 403 is a linear cylinder, and an output end of the linear cylinder is in transmission connection with the clamping assembly 402.

[0039] Preferably, the clamping driving part 403 can be one of a rack and pinion mechanism, a hydraulic cylinder, a linear cylinder and a linear motor.

[0040] The pressing plate 405 can shake or deflect during lifting, resulting in unstable clamping. The shaking or deflecting pressing plate 405 can cause uneven clamping force on the material, thereby affecting the positioning and processing precision of the material. Thus, in an embodiment, the clamping assembly 402 comprises a clamping frame 404, a pressing plate 405 and at least one linear bearing assembly 406. The clamping frame 404 is provided with a lifting groove 407, and the pressing plate 405 is arranged in the lifting groove 407.

The side pressing assembly 408 is in sliding connection with the clamping frame 404, and the side pressing driving part 409 drives the side pressing assembly 408 to retract along the width direction of the lifting groove 407 to clamp the material in the horizontal direction. When the material is placed in the clamping assembly 402, the side pressing assembly 408 will clamp the material from the side under the drive of the side pressing driving part 409. In this way, the material can remain stable and will not deviate left and right during the subsequent cutting or processing process.

[0042] The clamping device 4 needs to slide on the first slide rail 101, and if the positioning is unstable, the cutting accuracy will be affected, which may cause problems such as inaccurate product size and shape deformation. Therefore, in an embodiment, the clamping device 4 further comprises a fixing assembly, the fixing assembly comprising a fixing driving part 410 and a clamping block 411, the fixing driving part 410 being arranged on the rack 1, the fixing driving part 410 driving the clamping block 411 to rise and fall, and the bottom of the sliding seat 401 being provided with a clamping groove 412 matched with the clamping block 411.

With the disengagement of the clamping block 411 and the clamping groove 412, the clamping device 4 is free to move along the slide rail to the designated position; when the clamping device 4 is reset, the fixing driving part 410 will receive the instruction again and drive the clamping block 411 to rise, and with the clamping of the clamping block 411 and the clamping groove 412, the clamping device 4 is fixed on the rack 1 for subsequent operation.

[0043] In the present embodiment, the fixing driving part 410 is a linear cylinder, and the output end of the linear cylinder is in transmission connection with the clamping block 411.

[0044] Preferably, the fixing driving part 410 can be one of a gear and rack mechanism, a hydraulic cylinder, a linear cylinder and a linear motor.

[0045] In the production process, the work of identifying the tail section still needs to rely on manual operation. Therefore, in an embodiment, the pushing device 2 is provided with a sensor 7, and the sensor 7 is used to detect the size parameter and the feeding length of the material to be conveyed. With the conveying of the material, the tail section of the material passes through the sensor 7, and the sensor 7 outputs an instruction after receiving the signal to make the first connecting unit 12 and the second connecting unit 13 buckling connection, and the clamping device 4 and the pushing device 2 are combined into a whole, so that the pushing device 2 can drive the clamping device 4 to move on the first slide rail 101, reducing manual intervention and potential errors.

The housing 11 can also prevent fragments from splashing out during cutting, ensuring the safety of the operator. The protective doors 1101 allow the operator to easily open them when replacing the cutting tool or performing maintenance without the need to disassemble other components, thereby improving the operation efficiency and reducing the operation difficulty and complexity.

[0048] In summary, in use, the material to be cut is placed at the initial position of the material pushing device 2, the material pushing device 2 is started, the material is conveyed along the first sliding rail 101 to the cutting station, the clamping device 4 and the material returning device 3 clamp the two ends of the material respectively, then the cutting device 5 is started to cut the material, after cutting is completed, the material returning device 3 is started to take the finished product cut from the cutting station; when the material is cut to the end, the first connecting unit 12 at the bottom of the material pushing device 2 is connected with the second connecting unit 13 at the bottom of the clamping device 4, forming an integral whole, at this time, the material pushing device 2 drives the clamping device 4 and the end of the material to retreat away from the cutting device 5, so that the clamping device 4 clamps the end of the material, and then the material pushing device 2 drives the clamping device 4 and the end of the material to slide towards the cutting device 5. In this process, the material that cannot be cut due to insufficient sliding stroke of the material pushing device 2 can also be cut, realizing tailless cutting.
