[0025] The following will be combined with the drawings of the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a reverse extrusion deburring device for special-shaped punching, comprising a rotating column 1, a fixed cylinder 2 is fixedly connected inside the rotating column 1, a limiting cylinder 3 is fixedly connected inside the fixed cylinder 2, a first limiting block 4 is slidably connected inside the limiting cylinder 3, a first sliding column 5 is fixedly connected to the upper surface of the first limiting block 4, a sliding bar 6 is slidably connected inside the first sliding column 5, a sliding block 7 is fixedly connected to one end of the sliding bar 6, a first spring 8 is fixedly connected to the upper surface of the first sliding column 5, a round cap 10 is fixedly connected to the top of the first spring 8, a fixed block 9 is fixedly connected to the inner wall of the round cap 10, an outer wall of the sliding block 7 is slidably connected to the outer wall of the fixed block 9, an outer wall of the round cap 10 is slidably connected to the inner wall of the fixed cylinder 2, and a fixing component is fixedly connected to the upper surface of the rotating column 1;

[0027] Specifically, the rotating column 1 brings the fixed cylinder 2 into the inside of the anisotropic punching hole. When the round cap 10 slides along the inside of the anisotropic punching hole, the round cap 10 is squeezed and presses the first spring 8 to contract, thereby driving the first sliding column 5 to slide downward. Here, the rotating column 1 has a fixing effect on the fixed cylinder 2, and the round cap 10 has a fixing effect on the first spring 8. The first sliding column 5 slides downward and drives the first limit block 4 fixedly connected to the lower surface of the first sliding column 5 to slide on the inner wall of the limit cylinder 3, wherein the first limit block 4 has a fixing effect on the first sliding column 5, and the limit cylinder 3 has a limiting and fixing effect on the first limit block 4, and the fixed cylinder 2 has a fixing effect on the limit cylinder 3. It plays a fixing role. The first sliding column 5 drives the first limit block 4 to slide on the inner wall of the limit cylinder 3, while prompting the sliding bar 6 to slide inside the first sliding column 5, so that the outer wall of the sliding block 7 slides on the outer wall of the fixed block 9. The first sliding column 5 here plays a role of limiting the sliding of the sliding bar 6, and the round cap 10 plays a fixing role on the fixed block 9, so that the round cap 10 slides downward as a whole. When the round cap 10 completely passes through the special-shaped punching hole, the first spring 8 rebounds and drives the round cap 10 to move upward, driving the sliding bar 6 to slide inside the first sliding column 5 again, and prompting the outer wall of the sliding block 7 to slide on the outer wall of the fixed block 9.

[0028] Reference Figure 1 and Figure 4The fixing assembly includes a connecting column 11, the lower surface of the connecting column 11 is fixedly connected to the upper surface of the rotating column 1, and the upper surface of the connecting column 11 is fixedly connected to a mounting block 13; the outer wall of the connecting column 11 is slidably connected to a connecting cylinder 12, and the interior of the connecting cylinder 12 is slidably connected to a second sliding column 14;

[0029] Specifically, the connecting column 11 fixedly connected to the upper surface of the rotating column 1 slides along the inner wall of the connecting tube 12, and the connecting column 11 slides the mounting block 13 along the outer wall of the second rotating wheel 20, wherein the connecting column 11 fixes the mounting block 13 and can improve the stability of the fixed connection.

[0030] Reference Figure 4 , the outer wall of the second sliding column 14 is fixedly connected with a second limit block 15, and the outer wall of the second sliding column 14 is slidably connected with a second spring 16; one end of the second spring 16 is fixedly connected to the inner wall of the connecting tube 12, and one end of the second sliding column 14 is fixedly connected with a clamping block 17; the inside of the clamping block 17 is fixedly connected with a fixed column 18, and the outer wall of the fixed column 18 is rotatably connected with a first rotating wheel 19; the outer wall of the fixed column 18 is rotatably connected with a second rotating wheel 20, and the inside of the connecting tube 12 is fixedly connected with a dome 21; the outer wall of the first rotating wheel 19 is rotatably connected to the lower surface of the dome 21, the outer wall of the second rotating wheel 20 is rotatably connected to the lower surface of the dome 21, and the upper surface of the connecting tube 12 is fixedly connected with a rotating block 22;

[0031] Specifically, when the mounting block 13 slides along the outer wall of the engaging block 17, the engaging block 17 is subjected to pressure to drive the second limit block 15 to slide inside the connecting tube 12, wherein the second sliding column 14 fixes the second limit block 15, and the connecting tube 12 limits the sliding of the second sliding column 14. When the second limit block 15 slides inside the connecting tube 12, the engaging block 17 presses the second spring 16 to contract. At this time, the second limit block 15 is separated from the fitting state with the connecting tube 12, and the second limit block 15 limits and fixes the second sliding column 14. The movement of the engaging block 17 drives the fixing column 18 to move, so that the fixing column 18 and the second rotating wheel 20 slide on the lower surface of the dome 21. Here, the engaging block 17 fixes the fixing column 18, and the fixing column 18 limits the rotation of the first rotating wheel 19 and the second rotating wheel 20.

[0032] Working principle: when the device is needed, the rotating column 1 brings the fixed cylinder 2 into the inside of the special-shaped punching hole. When the round cap 10 slides along the inside of the special-shaped punching hole, the round cap 10 is squeezed and presses the first spring 8 to contract, thereby driving the first sliding column 5 to slide downward. The first sliding column 5 slides downward, and the first limiting block 4 fixedly connected to the lower surface of the first sliding column 5 slides on the inner wall of the limiting cylinder 3. The first sliding column 5 drives the first limiting block 4 to slide on the inner wall of the limiting cylinder 3, while prompting the sliding bar 6 to slide inside the first sliding column 5, so that the outer wall of the sliding block 7 slides on the fixed block 9. The outer wall of the sliding block 7 is pressed against the outer wall of the fixed block 9, thereby making the round cap 10 slide downward as a whole. When the round cap 10 completely passes through the special-shaped punching hole, the first spring 8 rebounds and drives the round cap 10 to move upward, driving the sliding bar 6 to slide inside the first sliding column 5 again, and causing the outer wall of the sliding block 7 to slide on the outer wall of the fixed block 9, thereby achieving the purpose of removing burrs from punching holes of different sizes, and then it can be used to process products of various sizes and shapes, enhancing its versatility and reducing the cost and time of mold change of the production line. The connecting column 11 fixedly connected to the upper surface of the rotating column 1 slides in along the inner wall of the connecting cylinder 12, thereby making the connecting The column 11 slides the mounting block 13 along the outer wall of the second rotating wheel 20, wherein the connecting column 11 plays a fixing role on the mounting block 13, which can improve the stability of the fixed connection. When the mounting block 13 slides along the outer wall of the snap block 17, the snap block 17 is subjected to pressure to drive the second limit block 15 to slide inside the connecting tube 12. When the second limit block 15 slides inside the connecting tube 12, the snap block 17 presses the second spring 16 to contract. At this time, the second limit block 15 is separated from the fitting state with the connecting tube 12, and the snap block 17 moves to drive the fixing column 18 to move, so that the fixing column 1 8 and the second rotating wheel 20 slide on the lower surface of the dome 21. When the outer wall of the mounting block 13 is completely stuck in the rotating column 1, the grinding tool can be quickly and easily replaced, the downtime can be reduced, and the operation efficiency and continuity of the production line can be improved. The device can not only remove burrs from punching holes of different sizes, but also can be used to process products of various sizes and shapes, thereby enhancing its versatility and reducing the mold change cost and time of the production line. It can also quickly and easily replace the grinding tool, reduce downtime, and improve the operation efficiency and continuity of the production line.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
