Description

Technical Field

[0001] This utility model relates to the field of high alloy steel processing technology, and in particular to an automatic burr removal device applied to high alloy steel casting and rolling. Background Technology

[0002] High-alloy steel is widely used in high-end manufacturing due to its excellent strength, hardness, wear resistance, and corrosion resistance. In the continuous casting and rolling process of high-alloy steel sheet and strip, when the high-temperature molten steel solidifies at the gap between the casting and rolling rolls, irregular, extremely hard burrs inevitably form on the edges of the sheet and strip. The presence of these burrs not only seriously affects the appearance quality and dimensional accuracy of the sheet and strip, but also increases the risk of equipment roll surface scratches, sheet surface abrasions, and strip breakage in subsequent processes such as coiling, straightening, cold rolling, and pickling, significantly reducing production efficiency and product yield. Therefore, an efficient, stable, and automated online burr removal device is needed to remove these harmful burrs in real time, ensuring product quality, improving production continuity, and protecting downstream key equipment.

[0003] Currently, the existing technology used in the steel industry to remove burrs from the edges of cast and rolled strips mainly relies on rigid contact scraping or fixed-position rotary milling. It depends on the physical strength of hardened cutting tools to forcibly remove burrs from the edges of the strips through direct, rigid contact and relative movement.

[0004] However, existing technologies have some shortcomings. Due to the use of rigid fixed structures and the lack of effective adaptive adjustment mechanisms, existing devices are unable to effectively cope with the unavoidable edge position fluctuations of cast and rolled strips during the production process, resulting in unstable cleaning effects and problems such as incomplete burr removal and over-cutting. This not only affects the cleaning quality but also aggravates grinding wheel wear and damages the surface of the cast and rolled parts, making it difficult to meet the production requirements of high consistency and low loss. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an automatic burr removal device for high alloy steel casting and rolling, which aims to improve the problem that existing devices are unable to effectively deal with the edge position fluctuations that are unavoidable during the production process of cast and rolled strips, resulting in unstable cleaning effect and difficulty in meeting the production requirements of high consistency and low loss.

[0022] Working principle: When deburring high-alloy steel castings, motor 5 is first started. Through the drive of the rotating wheel 3 and the synchronous belt 4, the rollers 2 inside the support frame 1 rotate synchronously, conveying the high-alloy steel castings. After the castings are in place, the hydraulic rod 10 extends and retracts, pushing the slide plate 6 along the slide rail 7 to adjust the position of the grinding wheel 20, which is indirectly connected to the slide plate 6. Simultaneously, the rotating shaft 11, rotating plate 12, and connecting rod 13 work together to help the slide plate 6 maintain horizontal stability during movement, preventing wobbling and ensuring accurate relative positioning between the grinding wheel 20 and the casting. The guide roller 24 contacts the surface of the casting, and the elastic force of the spring 22 keeps the guide roller 24 close to the workpiece, assisting in positioning and preventing the casting from shifting. Then, motor 19 is started to drive the grinding wheel 20 to rotate at high speed, removing burrs from the surface of the casting. During grinding, the telescopic rod 16 and spring 17 form a buffer structure. The telescopic rod 16 provides guidance, and the spring 17 provides elastic buffering, allowing the outer shell 18 to adaptively adjust laterally to adapt to the edge fluctuations of the cast and rolled parts, avoiding missed scraping or over-cutting, improving the consistency of cleaning and protecting the cast and rolled parts, reducing mechanical impact, and extending the equipment life. While the grinding wheel 20 rotates, the fan 26 and water pump 31 are started. The dust generated by grinding is adsorbed through the air duct 29 and sucked into the dust storage bin 28 to reduce pollution. The water pump 31 draws water from the water tank 30 and delivers it to the spray head 33 through the water pipe 32, spraying out a mist of water to cool the grinding wheel 20 and the cast and rolled parts, thereby reducing the wear of the grinding wheel 20, preventing the workpiece from thermally deforming, and at the same time wetting the dust, enhancing the dust removal effect, reducing secondary pollution, and thus improving the reliability of the system and the working environment.
