[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0029] like Figure 1-Figure 9 The special-shaped punching machine with a rotating structure shown in the figure comprises a device body 1, a moving frame 2 is movably installed inside the device body 1, a punching mechanism is arranged above the front end of the moving frame 2, a connecting head 4 is fixedly installed below the front end of the moving frame 2, an end plate 17 is fixedly installed at the front end of the connecting head 4, a cutting die 6 is fixedly installed on the upper surface of the connecting head 4, a cutting hole 7 is opened through the upper surface of the cutting die 6, an arc-shaped sealing plate 8 is fixedly installed on the inner side of the connecting head 4, and the upper surface of the arc-shaped sealing plate 8 is slidable. There are two vertical connecting plates 10 that are dynamically connected. The upper side of the vertical connecting plates 10 is fixedly connected with a guide bar 9. The upper end of the guide bar 9 is located at the rear and lower side of the knife hole 7. The front end of the guide bar 9 passes through the inner side of the end plate 17. The front ends of the two vertical connecting plates 10 are fixedly connected with an external connecting plate 11 that extends downward. A distance adjusting mechanism is provided at the lower ends of the two external connecting plates 11. A baffle box 18 is clamped on the front surface of the end plate 17. The front end surface of the guide bar 9 contacts the inner surface of the baffle box 18. The external connecting plate 11 is located on the inner side of the baffle box 18.

[0030] like Figure 3 As shown, a CNC workbench 3 is provided on the inner bottom surface of the device body 1, and the movable end of the CNC workbench 3 is fixedly mounted on the lower surface of the moving frame 2. The CNC workbench 3 includes a servo rotating platform, which is used to control the rotation of the moving frame 2, and then controls the servo rotating platform to move forward and backward through a screw slide.

[0031] like Figure 3 , Figure 4 As shown, the punching mechanism includes a motor 30 fixedly mounted at the front end of the upper surface of the moving frame 2, a driving disc 31 is fixedly mounted on the output shaft of the motor 30, a transmission rod 32 is rotatably connected to the edge of the front surface of the driving disc 31, a vertical slide plate 33 is rotatably connected to the lower end of the transmission rod 32, the vertical slide plate 33 is slidably matched with the moving frame 2 in the vertical direction, and a cutter head 34 is fixedly mounted on the lower surface of the vertical slide plate 33. When the motor 30 is driven, the driving disc 31 drives the transmission rod 32 to rotate, thereby causing the vertical slide plate 33 to reciprocate vertically, thereby causing the cutter head 34 to reciprocate up and down.

[0032] like Figure 7As shown, the distance adjustment mechanism includes a mounting plate 13 fixedly mounted on the lower surface of the connector 4, a guide block 14 fixedly mounted on one side surface of the mounting plate 13, a bidirectional threaded rod 15 rotatably penetrates through one side surface of the mounting plate 13 and near the front of the guide block 14, a distance adjustment plate 12 is fixedly connected to the lower end of the external plate 11, the upper side of the distance adjustment plate 12 is in sliding contact with the lower surface of the connector 4, the bidirectional threaded rod 15 threads penetrate through the two distance adjustment plates 12, the lower side of the distance adjustment plates 12 is slidably sleeved on the upper surface of the guide block 14, one end of the bidirectional threaded rod 15 is fixedly connected to a polygonal block 16, and the polygonal block 16 is convenient for users to rotate with the help of a wrench. The surface of the bidirectional threaded rod 15 is provided with bilaterally symmetrical threads, and when rotating, the two distance adjustment plates 12 can be moved closer to or away from each other.

[0033] like Figure 8 As shown, the inner bottom surface of the shielding box 18 is provided with an arc bottom 19. The design of the arc bottom 19 can make small debris more concentratedly collected at the lower edge of the arc bottom 19, and when pouring, the curved surface of the arc bottom 19 can help small debris fall out.

[0034] like Figure 8 , Fig. 9 As shown, a docking plate 20 is fixedly connected to the upper surface of the shielding box 18, a socket 21 is formed through the front surface of the docking plate 20, an insert block 22 is fixedly connected to the front surface of the end plate 17, the insert block 22 slides through the inner side of the socket 21, and a clamping block 27 is connected to one side of the insert block 22 through an elastic mechanism, and the clamping block 27 abuts against the inner side of the socket 21. The elastic force of the elastic mechanism makes the insert block 22 and the clamping block 27 tightly supported on the inner side of the socket 21 to ensure the stability of the docking plate 20.

[0035] The elastic mechanism includes a guide rod 25 fixedly connected to one side surface of the block 27, a fixed cylinder 23 fixedly connected to one side surface of the insert block 22, the guide rod 25 is slidably inserted into the inner side of the fixed cylinder 23 and a sliding disk 26 is fixedly connected to the end thereof, a compression spring 24 is arranged inside the fixed cylinder 23, and the sliding disk 26 is fixedly connected to one end of the compression spring 24. The elastic force of the compression spring 24 allows the block 27 to stably press against the inner side of the socket 21.

[0036] A toggle plate 28 is fixedly connected to the front surface of the block 27, and a chamfered edge 29 is provided on one side edge of the block 27 away from the plug block 22. The chamfered edge 29 plays a guiding role. When the docking plate 20 is installed, the side edge of the socket 21 will contact the chamfered edge 29, pushing the block 27, so that the block 27 moves toward the plug block 22.

[0037] like Figure 5 , Figure 6As shown, the upper surface of the connector 4 is fixedly connected with a knife seat 5, the lower end of the knife die 6 is fixedly connected to the upper surface of the knife seat 5, and the knife hole 7 passes through the inner side of the knife seat 5 to ensure that the generated debris can fall to the inner side of the connector 4.

[0038] When the plate passes through the surface of the cutting die 6, the operation of the motor 30 causes the driving disc 31 to rotate, and then the transmission rod 32 drives the vertical slide plate 33 to move up and down. The vertical slide plate 33 moves up and down reciprocatingly, and cooperates with the lateral movement of the plate body to continuously punch holes at different positions. The debris generated in the punching falls through the knife hole 7, and the concave debris crosses the two guide bars 9 and slides down. After sliding to the bottom, it is blocked by the inner surface of the shielding box 18 and accumulates there. The small debris generated in the punching process falls on the surface of the arc-shaped sealing plate 8 and slides down. It slides from the front end to the inner side of the arc-shaped bottom 19 for centralized collection. Later, the shielding box 18 is removed to allow the concave debris to slide down from the front end of the guide bar 9 for centralized collection. The container can be used to directly receive the concave debris. Since the surface of the guide bar 9 is smooth and the contact area with the concave debris is small, and the concave debris is arranged more neatly on the surface of the guide bar 9, it can fall out smoothly in order without obstruction when sliding, so as to improve the convenience of collection. Since the concave debris is neatly arranged, it is not easy to cause blockage at the debris discharge position due to interweaving.

[0039] The user rotates the polygonal block 16 to rotate the bidirectional threaded rod 15, thereby causing the two distance adjusting plates 12 to move closer to or away from each other, thereby changing the distance between the two guide bars 9 to adapt to and drag the inner side of the concave debris near the two corner positions, preventing the concave debris from rotating and falling due to a small spacing, and preventing the concave debris from getting stuck due to a large gap.
