In addition, when the third pulley 605 rotates, the rust removal box 701 is driven to swing back and forth on the surface of the machine base 1 through the eccentric shaft 715 and the swing arm 714, thereby further improving the rust removal effect.

[0033] Specifically, the working process or working principle of the PC steel bar cutting device and the cutting method thereof is as follows: when in use, the PC steel bar to be cut is placed on the surface of the feeding roller 2 and passes through the guide hole, the first motor 509 drives the first rotating shaft 507 to rotate, and the convex block 508 drives the support arm 503 to drive the upper blade 502 to move downward to shear the steel bar, and then under the action of the first spring 506, the upper blade 502 is driven to move upward and reset, and this cycle is repeated, and the convex block 508 drives the upper blade 502 to move downward to cut the steel bar. When the rod is sheared, the second spring 512 drives the piston 511 to move downward, and the coolant in the solution chamber 515 is pumped into the pump liquid box 510. After the shearing is completed, when the first spring 506 drives the upper blade 502 to move upward, the protrusion 508 drives the push plate 514 to drive the piston 511 to move upward, and the coolant in the pump liquid box 510 is injected into the branch pipe 518, and sprayed by the nozzle 519 to the surface of the upper blade 502 and the lower blade 501, so as to cool the blades and wash the debris on the surface of the blades to ensure the shearing quality of the steel rod.

[0034] The coolant flowing down from the surface of the lower blade 501 and the upper blade 502 enters the liquid guide groove 601, and flows into the solution cavity 515 after being filtered by the filter cartridge 602, and is reused. As the filter cartridge 602 rotates, the debris on the surface of the filter cartridge 602 is scraped into the groove 606. As the filter cartridge 602 rotates, when the groove 606 rotates to the side wall of the chip groove 607, the scraper 609 extends into the groove 606, scrapes the debris in the groove 606 into the chip groove 607, and drops it into the collection box 608 for easy cleaning.

[0035] After the PC steel rod passes through the rust removal box 701, the second motor 706 can drive the first gear 707 and the first gear ring 705 to rotate, thereby driving the two rotating wheels 704 and the rust removal roller 708 to rotate, and the surface of the steel rod is polished and rust-removed to improve the quality of the steel rod. When the rotating wheel 704 rotates, the second gear ring 711 can drive the second gear 712 to drive the rust removal roller 708 to rotate, thereby improving the rust removal effect. In addition, when the third pulley 605 rotates, the eccentric shaft 715 and the swing arm 714 can drive the rust removal box 701 to swing back and forth on the surface of the machine base 1, thereby further improving the rust removal effect.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
