[0020] The present utility model will be further described in detail below with reference to the drawings.
[0021] Combined with the attachedFigure 2 and the attached Figure 4 On both the front and rear sides of the workbench 1, side plates 3 are connected and provided. Between the side plates 3 and on one side of the workbench 1, a rotating roller 4 is rotatably connected. Equally spaced annular grooves 9 are connected to the rotating roller 4. The arrangement of the annular grooves 9 provides a certain grasping force for the cut metal shrapnel, and the metal shrapnel can also leak out between two adjacent annular grooves 9, facilitating the discharging. The rotating roller 4 is driven by a reduction motor 5 provided on the front side of the side plate 3. A bulletproof shooting structure is connected to the upper surface of the side plate 3. The bulletproof shooting structure includes a support plate 13 connected to the upper surface of the side plate 3, an arc-shaped panel 14 connected to the upper surface of the support plate 13, and an arc-shaped protection plate 15 connected between the arc-shaped panels 14.
[0022] Combined with the attached Figure 3 On both the front and rear sides of the workbench 1, cylinders 6 are connected and provided. The extending end of the cylinder 6 is connected with a disc 18. The disc 18 is connected to the lifting plate 7 through bolts. A buffer guiding structure is connected between the lifting plate 7 and the workbench 1. The buffer guiding structure includes a sliding hole connected to the upper surface of the lifting plate 7, a sliding rod 16 connected to the upper surface of the workbench 1 and adapted to the sliding hole, and a spring 17 is provided between the lifting plate 7 and the workbench 1. The spring 17 is sleeved outside the sliding rod 16. The sliding rod 16 provides a good guiding function, and the spring 17 ensures that the downward impact force will not be too large, preventing damage to the cutting tool 2.
[0023] Combined with the attached Figure 1 and the attached Figure 3 Under the lifting plate 7, a tool box 8 is connected. Under the tool box 8, the cutting tool 2 is connected. On the workbench 1 and below the cutting tool 2, a tool groove 10 is provided. A pushing structure is connected to the upper surface of the workbench 1. A pushing piece groove 11 perpendicular to the tool groove 10 is provided on the upper surface of the workbench 1. A slider 12 is slidably arranged in the pushing piece groove 11. The slider 12 slides in the pushing piece groove 11. The pushing piece groove 11 not only plays a guiding role but also a limiting role, ensuring the correct position of the metal shrapnel during cutting. The pushing structure includes an intermediate plate 19 connected to the middle of the upper surface of the workbench 1, an electric push rod 20 connected to one side of the intermediate plate 19, a push plate 21 connected to the extending end of the electric push rod 20, and the push plate 21 is connected to the slider 12. A temporary storage box 22 is connected to the upper surface of the workbench 1, and the temporary storage box 22 is used to store the finished metal shrapnel.
[0024] Specific embodiments of the present utility model: When the present utility model is in use, the metal shrapnel plate to be cut is placed in the pushing plate groove 11. The electric push rod 20 is started to push the pushing plate 21, so that the slider 12 slides in the pushing plate groove 11. When the metal shrapnel plate is pushed to the knife groove 10, the air cylinder 6 retracts, and the lifting plate 7 slides down on the sliding rod 16. The spring 17 plays a role in decelerating and buffering, driving the knife box 8 and the cutting knife 2 to fall, cutting the metal shrapnel into shape. Some of the metal shrapnel will fly off and fall onto the rotating roller 4 after touching the arc-shaped protection plate 15. Some metal shrapnel and scraps that do not fly off are pushed onto the rotating roller 4 by the pushing plate 21. The annular groove 9 increases the grasping points of the metal shrapnel, making it more convenient to move on the rotating roller 4. A receiving place is arranged below the rotating roller 4 for receiving. After receiving and sorting, the qualified metal shrapnel is temporarily stored in the temporary storage box 22.
