Description

Technical Field

[0001] The invention relates to the technical field of continuous casting and rolling technology, and in particular to a continuous casting and rolling machine for continuous production of copper rods. Background Art

[0002] Continuous casting and rolling is the full name of continuous casting and rolling. It is a metal rolling process that pours liquid metal into a continuous casting machine to cast a steel billet, and then directly enters the hot rolling unit to roll it into shape after being kept warm in a soaking furnace for a certain period of time without cooling. Continuous casting and rolling process is a common production process for copper rod production today.

[0003] Prior art Chinese patent publication number CN217748653U discloses a continuous casting and rolling mill suitable for copper rod production, including: a cabinet, a support vertical plate, a first roller group, a second roller group, a copper rod rolling device and a roller cleaning device; the support vertical plates are provided with four, and the support vertical plates are respectively fixedly mounted on the upper side of the cabinet; the first roller group is rotatably connected to the front side of the rearmost support vertical plate; the second roller group is rotatably connected to the front side of the middle and rear support vertical plate, and the second roller group is symmetrical with the first roller group in structure; the copper rod rolling device is arranged above the cabinet; the roller cleaning device is arranged above the cabinet. The utility model cleans the rollers through the roller cleaning device, thereby improving the production quality of copper rods;

[0004] The patent publication number is: CN 219851356 U, which discloses a continuous casting and rolling mill suitable for copper rod production, including a bottom plate, a continuous casting module is fixedly connected to one side of the top of the bottom plate, a plurality of rolling rings are fixedly connected to one side of the continuous casting module, three support frames are fixedly connected to the inner side of the rolling rings, a rolling roller is rotatably connected to the inner side of the support frame, and a shaping tube is fixedly connected to one side of the top of the bottom plate. The copper rod is directly rolled to the required size, and the continuous decreasing rolling method can speed up the rolling efficiency. By arranging a cleaning ball on the support frame, the cleaning ball will rotate and interact with the cleaning ball during the rotation of the rolling roller, thereby cleaning the copper rod debris remaining on the rolling roller, so as to avoid the copper rod debris attached to the rolling roller affecting the subsequent rolling.

[0005] In the above-mentioned prior art, a single cleaning brush wheel or cleaning ball is used to clean the copper chips on the roller. However, after the copper chips are cleaned, they will still remain attached to the surface of the cleaning brush wheel or the cleaning ball. If they are not thoroughly removed, the copper chips may re-attach to the roller and cause the copper chips on the roller to adhere to the surface of the copper rod, affecting the processing quality of the copper rod. Therefore, in batch processing and production, a continuous casting and rolling machine with a thorough cleaning function is needed for continuous production of copper rods. Summary of the invention

[0034] A scraper 13 is connected to the vertical plate 1, and the shape of the scraper 13 is adapted to the periphery of the roller 3. The end face of the scraper 13 is vertically rotatably connected to a rotating shaft 18, and a scraper strip 17 is fixed to the rotating shaft 18. The scraper strip 17 is in sliding contact with the surface of the scraper 13. The end face of the mounting seat 8 is screwed to a motor seat, and a motor 5 is installed on the motor seat. The output shaft of the motor 5 is drivingly connected to one of the rollers 3. The roller 3 is coaxially connected to a bevel gear 2, and two adjacent bevel gears 2 are externally meshed. The motor 5 drives the roller 3 to rotate, so that the roller 3 drives the bevel gear 2 to rotate. Through the meshing of the bevel gear 2, the three rollers 3 can be driven to rotate synchronously. When the roller 3 rotates, the copper rod can be bitten into the copper rod biting port;

[0035] Three brackets 10 are connected to the surface of the vertical plate 1. The positions of the three brackets 10 correspond to the three rollers 3 one by one. A sliding rod 12 is passed through the bracket 10. The sliding rod 12 slides freely horizontally on the bracket 10. One end of the sliding rod 12 facing the roller 3 is fixedly connected to the scraper 13. The other end of the sliding rod 12 is fixedly sleeved with a fixing ring 9. A tension spring 14 is sleeved around the sliding rod 12. The two ends of the tension spring 14 are respectively fixedly connected to the bracket 10 and the end face of the fixing ring 9 one by one. The tension spring 14 generates tension on the fixing ring 9, so that the fixing ring 9 drives the sliding rod 12 to move in the direction of the roller 3, and the rotation A gear portion 19 is provided on the moving shaft 18, and the rack rod 20 is externally meshed with the gear portion 19. A connecting arm 11 is fixedly connected to the periphery of the fixing ring 9, and a push rod 15 is fixedly connected to the connecting arm 11. The push rod 15 slides freely horizontally on the bracket 10. An annular flange 7 is coaxially fixed to the end face of the roller 3, and a cam block 6 is fixed to the periphery of the annular flange 7. A ball 16 is rotatably embedded at the end of the push rod 15. When the roller 3 rotates, the ball 16 alternately rolls and contacts the cam block 6 and the annular flange 7.
