Description

Technical Field

[0001] The utility model relates to the technical field of slab deburring, in particular to a deburring machine scraper turning over self-cleaning mechanism. Background Art

[0002] With the development of technology, many deburring machines are equipped with self-cleaning mechanisms. For example, the Chinese utility model patent with authorization announcement number CN215468571U discloses a new automatic deburring machine with a cleaning structure, which drives the fan to rotate by a motor, and prevents the burrs from splashing upward by blowing air downward, and sprays water through the water outlet on the inner wall of the cover body to achieve burr flushing on the surface of the workpiece. For example, the Chinese utility model patent with authorization announcement number CN207656396U also discloses a deburring machine that is easy to clean, in which an air induced draft component and a chip collection component are arranged inside the deburring machine. The device attracts burrs and waste chips through the air induced draft fan, and uses an electromagnet to absorb the burrs and waste chips.

[0003] However, for the scraper-type deburring machine for slab processing, the processing area is relatively large, and the above-mentioned cleaning device often cannot meet the cleaning requirements of the slab deburring machine. After the scraper removes the burrs, some of the metal burrs that fall from the slab often stay on the upper surface of the scraper, or on the crossbeam box of the scraper. When the next part of the slab is deburred, the old burrs will be twisted into the new burrs, which will increase the difficulty of removing the new burrs. In addition, the old burrs cover the cutting edge of the scraper, which will also cause the cutting edge to be unable to directly contact the new burrs, thereby reducing the deburring rate of the scraper deburring machine. In addition, when removing burrs, some iron oxide scales and other residues will fall into the gap between the scraper seats. In the long run, the scraper may be stuck and not rebound, which will lead to equipment failure, reduced deburring rate and other problems. In addition, due to processing and production needs, the scraper of the slab deburring machine also needs to be cleaned in time.

[0004] In order to solve the above problems, some solutions have also appeared in the prior art. For example, the Chinese utility model patent with authorization announcement number CN211438421U discloses a continuous casting billet deburring machine, but it uses a flipping mechanism to flip the beam box 90°, and then uses manual or other methods to clean out the accumulated dust from the ash pouring port, which is not very convenient to clean.
