When the mold 42 is working, the generated metal debris splashes around. The annular storage box 512 is set so that the splashed metal debris is stored in the annular storage box 512, and part of it adheres to the inner wall of the inner ring of the annular storage box 512 to prevent the metal debris from splashing into the CNC machine tool 1.

[0048] Specifically, the transmission member 55 operates and drives the horizontal scraping assembly 52 and the vertical scraping assembly 53 to scrape the metal debris at the inner ring of the annular storage box 512 and drop it to the lower rectangular opening 542. At the same time, the servo motor 555 is started to drive one of the first gears 554 to rotate. Through the engagement between the two first gears 554 and the first toothed belt 551, the two first gears 554 are driven to rotate, thereby driving the rotating roller 541 and the movable roller 545 to rotate at the same time. When the rotating roller 541 rotates, it drives the outer peripheral transport plate 543 to rotate with the rotating roller 541 as the axis, thereby the lower rectangular opening 542 is moved. The metal debris at the outlet 542 is transported to the discharge outlet 546, and is hingedly connected to the transport plate 543 and the rotating roller 541, so that when one end of the transport plate 543 contacts the inner wall of the annular storage box 512, the transport plate 543 itself rotates and scrapes the inner wall of the annular storage box 512, thereby scraping off the metal debris on the inner wall of the annular storage box 512.

The bottom of the side rectangular opening 532 is fixedly connected with an inclined plate 535, and the top inclination angle of the inclined plate 535 is in contact with one side of the vertical transmission toothed belt 531;

[0051] The transmission member 55 further includes a worm wheel 556 and a worm 557. The worm 557 is fixedly arranged on the outer periphery of the rotating rod 552. A transverse shaft 558 is fixedly connected to the axis of the worm wheel 556. The transverse shaft 558 is rotatably arranged in the annular storage box 512 through a bearing. The worm wheel 556 and the worm 557 are meshingly connected. One end of a transverse rod 533 and one end of the transverse shaft 558 both extend outside the fixed plate 511. One end of the transverse rod 533 and one end of the transverse shaft 558 are both fixedly connected to a second gear 559. The outer peripheries of the two second gears 559 are sleeved with a second toothed belt 5510 and meshingly connected with the second toothed belt 5510.

[0052] Specifically, when the servo motor 555 drives the rotating rod 552 to rotate, the worm 557 is driven to rotate, and the meshing connection between the worm wheel 556 and the worm wheel 557 drives the worm wheel 556 to rotate, thereby driving the horizontal shaft 558 to rotate, and then driving one of the second gears 559 fixedly connected to the horizontal shaft 558 to rotate, and through the meshing connection between the two second gears 559 and the second toothed belt 5510, the other second gear 559 is driven to rotate, thereby driving one of the cross bars 533 to rotate, and through the meshing connection between the vertical transmission toothed belt 531 and the first tooth grooves 534 on the outer periphery of the two cross bars 533, the vertical transmission toothed belt 531 is driven to rotate. During the rotation of the vertical transmission toothed belt 531, the metal debris on the outside of the vertical transmission toothed belt 531 is scraped off by the setting of the inclination angle of the top end of the inclined plate 535 being in contact with one side of the vertical transmission toothed belt 531.

[0053] Embodiment 4:

[0054] The difference from the above-mentioned embodiment 3 is that, see Figure 9-12 For the above-mentioned transverse scraping assembly 52, the transverse scraping assembly 52 includes a transverse transmission toothed belt 521, a top rectangular opening 522 is opened at the top of the inner ring of the annular storage box 512, and round rods 523 are rotatably connected to the two sides of the top of the annular storage box 512 through bearings, and the outer circumference of the round rods 523 is opened with second tooth grooves 524.

[0055] The transverse scraping assembly 52 further includes a connecting rod 525, which is disposed at the top rectangular opening 522 and is rotatably connected to the annular storage box 512 through a bearing. A plurality of scraping plates 526 are hingedly connected to the outer periphery of the connecting rod 525. A second torsion spring 527 is installed at the hinged position of the plurality of scraping plates 526 and the connecting rod 525. The scraping plates 526 are in contact with the outer side of the transverse transmission toothed belt 521.

[0056] The transmission member 55 further includes a third toothed belt 5511. One end of the round rod 523, one end of the other cross rod 533 and one end of the connecting rod 525 all extend to the outer periphery of the fixed plate 511. One end of the round rod 523, one end of the other cross rod 533 and one end of the connecting rod 525 are all fixedly connected with a third gear 5512. The third toothed belt 5511 is sleeved outside the third gear 5512 and meshedly connected with the third gear 5512.

[0057] Specifically, when the cross bar 533 at the bottom of the vertical transmission toothed belt 531 rotates, the vertical transmission toothed belt 531 is meshed with the two cross bars 533, so that the cross bar 533 at the top of the vertical transmission toothed belt 531 is driven to rotate, thereby driving one of the third gears 5512 to rotate, and the meshing connection between the three third gears 5512 and the third toothed belt 5511 drives the other two third gears 5512 to rotate, thereby driving the round rods 523 and the connecting rod 525 to rotate, and one of the round rods 523 rotates, and the transverse transmission toothed belt 521 rotates through the meshing connection between the transverse transmission toothed belt 521 and the second tooth grooves 524 on the outer peripheries of the two round rods 523, so that the transverse transmission toothed belt 521 moves the metal debris on its surface toward the connecting rod 525, and at the same time, the connecting rod 525 rotates, driving the multiple scraping plates 526 on the outer periphery to rotate with the connecting rod 525 as the axis, so that the scraping plates 526 scrape the metal debris on the outer surface of the transverse transmission toothed belt 521.

[0058] Working principle: The punch blank 3 is fixed by the three-jaw chuck 2, and the collection box 51 is installed on the outer periphery of the protective sleeve 43. The tailstock 41 drives the mold 42 to run and drives the mold 42 to move toward the punch blank 3. When the mold 42 contacts the punch blank 3, one side of the annular storage box 512 is in contact with one side of the punch blank 3. When the mold 42 works, the generated metal debris splashes around. Through the setting of the annular storage box 512, the splashed metal debris is stored in the annular storage box 512, and part of it adheres to the inner wall of the inner ring of the annular storage box 512.

[0059] When the servo motor 555 drives the rotating rod 552 to rotate, the worm 557 is driven to rotate, and the meshing connection between the worm wheel 556 and the worm wheel 557 drives the worm wheel 556 to rotate, thereby driving the horizontal shaft 558 to rotate, and then driving one of the second gears 559 fixedly connected to the horizontal shaft 558 to rotate, and the meshing connection between the two second gears 559 and the second toothed belt 5510 drives another second gear 559 to rotate, thereby driving one of the cross bars 533 to rotate, and the meshing connection between the vertical transmission toothed belt 531 and the first tooth grooves 534 on the outer periphery of the two cross bars 533 drives the vertical transmission toothed belt 531 to rotate. During the rotation of the vertical transmission toothed belt 531, the metal debris on the outer side of the vertical transmission toothed belt 531 is scraped off and falls into the lower rectangular opening 542 through the setting of the top inclination angle of the inclined plate 535 being in contact with one side of the vertical transmission toothed belt 531;

[0060] When the cross bar 533 at the bottom of the vertical transmission toothed belt 531 rotates, the cross bar 533 at the top of the vertical transmission toothed belt 531 is driven to rotate through the meshing connection between the vertical transmission toothed belt 531 and the two cross bars 533, thereby driving one of the third gears 5512 to rotate, and the meshing connection between the three third gears 5512 and the third toothed belt 5511 drives the other two third gears 5512 to rotate, thereby driving the round rod 523 and the connecting rod 525 to rotate, and one of the round rods 523 rotates. The transverse transmission toothed belt 521 is meshed with the second tooth grooves 524 on the outer periphery of the two round rods 523, and the transverse transmission toothed belt 521 rotates, so that the transverse transmission toothed belt 521 moves the metal debris on its surface toward the connecting rod 525. At the same time, the connecting rod 525 rotates, driving the plurality of scraping plates 526 on the outer periphery to rotate with the connecting rod 525 as the axis, so that the scraping plates 526 scrape the metal debris on the outer surface of the transverse transmission toothed belt 521 and drop it to the lower rectangular opening 542.

[0061] The servo motor 555 is started, driving one of the first gears 554 to rotate. The two first gears 554 are meshed with the first toothed belt 551, driving the two first gears 554 to rotate, thereby driving the rotating roller 541 and the movable roller 545 to rotate at the same time. When the rotating roller 541 rotates, the outer transport plate 543 is driven to rotate with the rotating roller 541 as the axis, thereby transporting the metal scraps from the lower rectangular opening 542 to the discharge port 546, and the metal scraps are transported to the discharge port 546 through the transport plate 543 and the rotating roller. The hinged setting of 541 allows the transport plate 543 to rotate and scrape the inner wall of the annular storage box 512 when one end of the transport plate 543 contacts the inner wall of the annular storage box 512, thereby scraping off metal debris on the inner wall of the annular storage box 512. At the same time, the movable roller 545 rotates and scrapes off the debris on the transport plate 543 through the setting of the scraper 547, thereby collecting the debris in the annular storage box 512 into the collection bin 548 at the bottom of the annular storage box 512.

[0062] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
