Description

Technical Field

[0001] This utility model relates to the field of metal rolling processing, and in particular to a double-fixed anti-adhesion structure for rough rolling guides. Background Technology

[0002] The double-fixed anti-adhesion structure of roughing mill guides is a key auxiliary device used in roughing mills to guide the workpiece smoothly through the rolling zone and limit the movement trajectory of the workpiece. At the same time, the double-fixed design inhibits the adhesion of iron oxide scale or metal debris of the workpiece to the surface of the guide rolls. It is widely used in roughing processing of metal materials such as steel and non-ferrous metals.

[0003] In the prior art, the usage process and operation steps of the roughing mill guide device are usually as follows: First, the guide device is fixedly installed in the designated position of the roughing mill by the base, ensuring that the guide frame is aligned with the rolling center line; then, according to the specifications and dimensions of the workpiece, the spacing and height of the guide rollers are manually adjusted so that the inner wall of the guide rollers matches the preset transmission path of the workpiece; before starting the roughing mill, the rotation flexibility of the guide rollers is checked, and some devices require manual application of lubricating medium to reduce friction.

[0004] In practical applications, during the rolling process, the surface of the guide rolls is prone to adhesion due to friction and oxidation of the high-temperature rolled workpiece. Traditional cleaning methods require manual operation during work breaks, which not only affects rolling efficiency but also easily leads to the accumulation of adhesion due to untimely cleaning, thereby affecting the guiding accuracy of subsequent rolled workpieces. Therefore, based on the above-mentioned problems, a double-fixed anti-adhesion structure for roughing guides has been introduced. Utility Model Content

[0007] The scraping mechanism includes a guide rod, the outer wall of which is fixedly connected to the outer wall of the guide roller frame. A curved plate is slidably connected to the outer wall of the guide rod. A scraper is fixedly connected to the lower extension end of the guide rod. A wedge block A is fixedly connected to the upper extension end of the curved plate. An outer slide rod is slidably connected to the inner wall of the guide roller frame. A connecting plate is fixedly connected to the outer wall of the outer slide rod. A wedge block B is fixedly connected to the outer wall of the connecting plate. A transmission mechanism is provided inside the outer slide rod.

[0008] As a further description of the above technical solution: the outer wall of the scraper is in contact with the outer wall of the guide roller body, and the outer wall of the wedge block B is in contact with the outer wall of the wedge block A.

[0009] As a further description of the above technical solution: a cleaning liquid tank is fixedly connected to the top of the guide frame, a connecting pipe is fixedly connected to the outer wall of the cleaning liquid tank, an electric nozzle is fixedly connected to the lower extension end of the connecting pipe, and the outer wall of the electric nozzle is fixedly connected to the outer wall of the guide roller frame.

[0010] As a further description of the above technical solution: the transmission mechanism includes an inner slide rod, the outer wall of the inner slide rod is slidably connected to the inner wall of the outer slide rod, and the outer wall of the outer slide rod is provided with a through groove.

[0011] As a further description of the above technical solution: a connecting block is fixedly connected to the outer wall of the inner slide rod, a connecting rod is fixedly connected to the outer wall of the connecting block, and a toothed plate is fixedly connected to the extension end of the connecting rod.

The wedge block B517 is fixedly connected to the outer wall of the connecting plate 516. The wedge block B517 presses against wedge block A514, causing the curved plate 512 to move downwards. A transmission mechanism 6 is provided inside the outer slide rod 515. The transmission mechanism 6 is used for… As the guide roller body 4 rotates, the outer wall of the scraper 513 contacts the outer wall of the guide roller body 4, and the outer wall of the wedge block B517 contacts the outer wall of the wedge block A514. A cleaning liquid tank 7 is fixedly connected to the top of the guide frame 2. The cleaning liquid tank 7 is used to store cleaning liquid for auxiliary cleaning. A connecting pipe 8 is fixedly connected to the outer wall of the cleaning liquid tank 7. The connecting pipe 8 is used to transport the cleaning liquid in the cleaning liquid tank 7. An electric nozzle 9 is fixedly connected to the lower extension end of the connecting pipe 8. The electric nozzle 9 is used to atomize and spray the cleaning liquid onto the outer wall of the guide roller body 4. The outer wall of the electric nozzle 9 is fixedly connected to the outer wall of the guide roller frame 3.

[0025] Reference Figures 1-3The transmission mechanism 6 includes an inner slide rod 611, which drives the connecting block 612 and the connecting rod 613 to reciprocate. The outer wall of the inner slide rod 611 is slidably connected to the inner wall of the outer slide rod 515. The outer wall of the outer slide rod 515 has a through groove, which provides movement space for the connecting block 612. The connecting block 612 is fixedly connected to the outer wall of the inner slide rod 611. The connecting block 612 is used to connect the inner slide rod 611 and the connecting rod 613. The connecting rod 613 is fixedly connected to the outer wall of the connecting block 612. The connecting rod 613 is used to transmit the force of the inner slide rod 611 to the toothed plate 614. The extended end of the connecting rod 613 is fixedly connected to the toothed plate 614. 4. The gear disk 615 is driven to rotate by meshing. The top of the guide roller body 4 is fixedly connected to the gear disk 615. The gear disk 615 drives the guide roller body 4 to rotate synchronously. The outer wall of the toothed plate 614 meshes with the inner wall of the gear disk 615. There are two sets of scraping mechanisms 5. The two sets of scraping mechanisms 5 are symmetrically installed at both ends of the outer wall of the guide roller frame 3 at equal intervals. The two sets of scraping mechanisms 5 can achieve comprehensive cleaning of the outer wall of the guide roller body 4. The top of the cleaning liquid tank 7 is provided with a feed port. The feed port is used to replenish the cleaning liquid tank 7. A manual valve 11 is provided at the connection between the connecting pipe 8 and the electric nozzle 9. The manual valve 11 is used to control the flow and shut-off of the cleaning liquid.

[0026] Working principle: The guide roller frame 3 serves as the core mounting carrier, with its inner wall rotatably connected to the guide roller body 4. Two sets of scraping mechanisms 5 are symmetrically arranged at the top to ensure comprehensive cleaning of the outer wall of the guide roller body 4. The guide rod 511 in each set of scraping mechanisms 5 is fixed to the outer wall of the guide roller frame 3, providing sliding guidance for the curved plate 512. The scraper 513 connected to the lower extension end of the curved plate 512 can be adjusted to make close contact with the outer wall of the guide roller body 4. The wedge block A514 at the upper extension end of the curved plate 512 cooperates with the wedge block B517 on the outer wall connecting plate 516 of the outer slide rod 515 slidably connected to the inner wall of the guide roller frame 3. The sliding of the outer slide rod 515 can push the wedge block B517 to squeeze the wedge block A514, thereby driving the curved plate 512 to move down along the guide rod 511, so that the scraper 513 is tightly attached to the outer wall of the guide roller body 4, realizing the fixed attachment of the scraping mechanism 5 and the guide roller body 4.

[0027] Meanwhile, the inner slide rod 611, which is slidably connected inside the outer slide rod 515, is connected to the connecting rod 613 through the outer wall connecting block 612. The toothed plate 614 at the extension end of the connecting rod 613 meshes with the gear disk 615 fixed at the top of the guide roller body 4. When the inner slide rod 611 is pulled back and forth, the inner slide rod 611 drives the connecting block 612, the connecting rod 613, and the toothed plate 614 to move back and forth synchronously. The reciprocating motion of the toothed plate 614 drives the gear disk 615 to rotate, thereby driving the guide roller body 4 to rotate around its own axis, so that all positions on the outer wall of the guide roller body 4 can fully contact the scraper 513. The scraper 513 continuously scrapes away the adhering material on the outer wall of the guide roller body 4 as it rotates. In addition, the top of the guide frame 2 The fixed cleaning fluid tank 7 is connected to the electric spray head 9 fixed on the outer wall of the guide roller frame 3 via the connecting pipe 8. The manual valve 11 at the connection between the connecting pipe 8 and the electric spray head 9 can control the flow of cleaning fluid. When auxiliary cleaning is needed, the manual valve 11 is opened, and the cleaning fluid in the cleaning fluid tank 7 is transported to the electric spray head 9 through the connecting pipe 8. The electric spray head 9 atomizes the cleaning fluid and sprays it onto the outer wall of the guide roller body 4. The cleaning fluid interacts with the adhesive to soften the adhesive. Combined with the scraping action of the scraper 513 and the rotation of the guide roller body 4, the removal effect of the adhesive is further improved, avoiding the guide structure jamming or rolling quality problems caused by the residue of the adhesive, and realizing the double fixed anti-adhesion function of the roughing guide.
