Description

Technical Field

[0001] The utility model belongs to the technical field of tungsten carbide rollers and relates to a tungsten carbide roller structure for cleaning a rolling mill. Background Art

[0002] A straightening machine is a device used to straighten metal profiles, bars, pipes, wire, and other materials. A straightening machine uses straightening rollers to compress the bar material, causing it to change its straightness. Typically, there are two rows of straightening rollers, with varying numbers of rollers. There are also two-roller straightening machines, which use the angles of the two rollers (with a concave center and a hyperbolic shape) to straighten materials of varying diameters.

[0003] The surface of existing straightening rollers directly contacts the material, and oil and debris easily accumulate in the contact area, leading to problems such as cracks on the roller surface. This requires regular inspection of the roller surface. Conventional inspection involves cleaning the roller surface after shutting down the machine, followed by gradual inspection using a flaw detector. However, the large size of the rollers makes manual rotation difficult, making cleaning and flaw detection challenging.

[0004] In summary, the utility model provides a tungsten carbide roller structure for cleaning a rolling mill. Summary of the Invention

[0037] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The application principle of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] Example 1

[0040] like Figure 1-7 As shown, an embodiment of the present invention is a tungsten carbide roller structure for cleaning a rolling mill, comprising a straightening machine frame 1, and rollers mounted in pairs up and down in the straightening machine frame 1;

[0041] like Figure 7 As shown, the roller includes a bearing seat 2, and there are two groups of bearing seats 2 in each group of rollers, and a main shaft 3 is installed between them; a roller 4 is installed outside the main shaft 3; the roller 4 is located between the two groups of bearing seats 2, and a tungsten carbide coating 5 is sprayed on the outside of the roller 4; the thickness of the tungsten carbide coating 5 is designed according to the requirements and can be processed by laser cladding spraying technology.

[0042] A frame body 6 is installed in the straightening machine frame 1, and a transverse shaft 7 is installed in the frame body 6. The transverse shaft 7 is movable and rotatable between the rollers 4 installed above and below, and the end of the transverse shaft 7 away from the frame body 6 is detachably connected to an adapter 8;

[0043] A detachable working piece is provided on the adapter 8 , and the working piece at least abuts against the roller 4 at the bottom.

[0044] like Figure 6As shown, a telescopic member is installed in the frame body 6, a transverse shaft 7 is installed in the middle of the telescopic member, and the outer portion of the transverse shaft 7 extends to the outside of the straightener frame 1 and is installed with a rotating handle 9. The rotating handle 9 is coaxially arranged with the transverse shaft 7 and fixedly connected. Correspondingly, the connection positions at both ends of the frame body 6 and the straightener frame 1 can be designed according to the actual straightener frame structure.

[0045] The workpiece is a cleaning ball 10, adapted to flexibly abut the surface of roller 4. This embodiment utilizes an external structure to clean the surfaces of both rollers without requiring manual insertion into the straightener. This embodiment utilizes a rotating central cylinder, allowing the support shaft at the top of the central cylinder to rotate axially in the vertical direction. This is then achieved by rotating the transverse shaft horizontally to adjust the horizontal height of the shaft and the end position of the workpiece. The telescopic position should be sufficient for the cleaning ball to clean the surfaces of the upper and lower rollers.

[0046] The cleaning ball 10 includes a support frame 101 connected to the adapter 8. A foam rubber 102 is mounted on the exterior of the support frame 101, adapted to abut against the surfaces of the upper and lower rollers 4. The frame 6 includes a protruding portion 61 extending away from the rollers 4. A telescopic member is mounted within the protruding portion 61. A positioning plate 62 is also mounted within the frame 6, on which a limit snap ring 63 is mounted. The limit snap ring 63 is adapted to pass through the rotating handle 9 and be secured to the positioning plate 62. The protruding portion 61 extends outward, away from the straightening machine frame, to reserve space for the entire workpiece and prevent interference with the material being straightened.

[0047] like Figure 5 As shown, the telescopic member includes a central cylinder 12, with short cylinders mounted at the upper and lower ends of the central cylinder 12. A support shaft 13 is mounted within the short cylinder, and the ends of the support shaft 13 away from the central cylinder 12 are connected to the upper and lower ends of the frame body 6. A connecting bearing 14 is mounted within the central cylinder 12, the outer ring of which is fixedly connected to the inner wall of the central cylinder 12, and the inner ring of which is fixedly connected to the main shaft 3. The frame body 6 has an installation cavity, and a connecting bearing 2 15 is mounted within the installation cavity; the inner ring of the connecting bearing 2 15 is connected to the outer end of the support shaft 13; and the outer ring of the connecting bearing 2 15 is fixedly connected to the inner wall of the installation cavity.

[0048] Example 2

[0049] like Figure 8-10The figure shows another embodiment of the present invention. Based on Example 1, the working piece is a flaw detection head 11, adapted to flexibly abut the surface of the roller 4. If the flaw detector is an eddy current flaw detector, it can achieve flaw detection without completely abutting the roller surface. The frame 6 is also mounted with a mounting frame 64, adapted to mount a flaw detector 65 connected to the flaw detection head 11. During use, the top of the flaw detection head is threadedly connected to the adapter 8, achieving a connection. The threaded connection can be adjusted up and down to detect flaws on the roller surface.

[0050] Correspondingly, the limiting clamp ring 63 includes a clamping belt 631 and a clamping plate 632. The clamping belt 631 is installed with connecting plates 633 above and below and is installed on the two sets of position plates 62. The clamping plate 632 is arc-shaped and suitable for clamping the transverse shaft 7 to prevent the transverse shaft from rotating inward and interfering with material straightening.

[0051] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations that come within the meaning and range of equivalents of the claims be embraced therein.

[0052] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
