[0028] The limiting mechanism includes a limiting seat 22 disposed on end plate 15 and end plate 27. A pressure seat 24 is radially slidably mounted on the limiting seat 22. A pushing part 25 is disposed on the pressure seat 24. A spring 26 is connected between the pushing part 25 and the limiting seat 22. A limiting gear 20 is rotatably mounted on the limiting seat 22. A push wheel 23 is disposed on the end face of the limiting gear 20. The push wheel 23 is used to push the pushing part 25. The limiting gear 20 meshes with the control gear ring 19.

[0029] The scraping and shielding mechanism includes arrayed and slidably arranged shielding scrapers 27 on the inner ring 16. The shielding scrapers 27 extend and retract to the inner side of the inner ring 16 to form a complete area with the surface of the inner ring 16. The shielding scrapers 27 extend to the outer side of the inner ring 16 and contact the inner wall of the positioning outer cylinder 6 to perform the scraping operation. A spring 28 is connected between the shielding scrapers 27 and the inner ring 16. The scraping and shielding mechanism also includes a mounting base 29 disposed inside the inner ring 16. A take-up and release motor 30 is disposed on the mounting base 29. A take-up and release gear ring 31 is disposed on the output shaft of the take-up and release motor 30.

[0030] The cleaning mechanism includes a scraping cylinder 13 located at the bottom of the positioning outer cylinder 6. A scraper 14 is provided on the telescopic rod of the scraping cylinder 13. A discharge groove is provided at the bottom of the positioning outer cylinder 6. The scraper 14 extends into the interior of the positioning outer cylinder 6 and contacts the outer side of the inner ring 16 and the end faces of end plate 15 and end plate 27, and performs scraping operations.

[0031] Operating principle: The copper workpiece is placed on the limiting mechanism. Specifically, for easy positioning, it first passes through the placement hole 801 on the push plate 8 and then into the limiting seat 22. The shielding frame 12 is rotated by the motor 11 so that the shielding frame 12 coincides with the placement hole 801, which facilitates the subsequent pushing of the workpiece. During processing, the cutting blade 5 is moved by the control cylinder 4. The cutting blade 5 is located inside the positioning outer cylinder 6 through the cutting hole 601. When the workpiece is on the limiting mechanism, the motor 18 works, that is, it controls the control gear ring 19 to rotate. The limiting gears 20 on each limiting mechanism rotate, and the push wheel 23 pushes the pushing part 25, that is, the pressure seat 24 moves inward to fix the workpiece.

[0032] The operation of motor 9 controls the rotation of the positioning disc, namely, the rotation of end plate 15, inner ring 16, and end plate 17, which in turn drives the workpiece to rotate. The workpiece is cut inside the positioning outer cylinder 6, which can block splashing molten metal. When each workpiece passes the cutter 5, end plate 17 acts as a shield, separating the workpieces and preventing splashing molten metal from falling onto other workpieces. When the positioning disc rotates, the take-up and release motor 30 operates, controlling the rotation of the take-up and release gear ring 31, which causes the take-up and release drum 32 to rotate. This allows the take-up and release rope 34 to control the take-up and release of the shielding scraper 27. The shielding scraper 27 retracts into the inner ring 16 to allow the cutter 5 to pass smoothly, thereby achieving the cutting of each workpiece in the circumferential direction. It should be noted that when the shielding scraper 27 contacts the inner wall of the positioning outer cylinder 6, it can perform a scraping operation on the inside of the positioning outer cylinder 6, that is, scraping off the attached molten metal residue.

[0033] After completing a cutting operation, the push plate 8 is moved by pushing the electric cylinder 7 to push the workpiece, and the cut workpiece falls into the collection box 2. When removing the metal residue attached to the inner wall of the positioning outer cylinder 6, the positioning disk is rotated, that is, the shielding scraper 27 rotates around the inner wall of the positioning outer cylinder 6 to achieve the cleaning operation. Furthermore, the shielding scraper 27 is retracted, and the outer end of the shielding scraper 27 forms a complete area with the surface of the inner ring 16. The scraping electric cylinder 13 controls the scraper 14 to move, and the scraper 14 extends into the interior of the positioning outer cylinder 6 and contacts the surface of the inner ring 16 and the end faces of end plate 15 and end plate 2 17. Combined with the rotation, various areas on the positioning disk can be scraped, that is, the attached molten metal residue can be removed.
