Description

Technical Field

[0001] This utility model relates to the field of surface treatment technology, and more specifically, to a laser strengthening device. Background Technology

[0002] As a key working component, the rollers of a rolling mill are subjected to severe wear, high temperature and pressure, and cyclic loads during production, making them prone to surface wear and fatigue cracks, which directly affect production efficiency and product quality. Traditional roller surface strengthening methods mainly include thermal spraying, welding, and carburizing, but these methods have limitations such as insufficient bonding strength, poor coating uniformity, large heat-affected zone, and susceptibility to deformation.

[0003] Chinese patent (application number: CN202311584536.8) discloses a composite reinforcement process for the working roller surface of a leveling machine. The process uses a combination of laser cladding and thermal spraying. First, a 2.5-3mm thick cladding layer is made on the roller surface, and then WC is sprayed to form a 0.1-0.15mm coating, which improves the crush resistance and wear resistance.

[0004] However, the aforementioned traditional equipment still has the problem of being difficult to adapt to rollers of different diameters. Utility Model Content

[0005] Therefore, in order to solve the problem that traditional equipment is difficult to adapt to rollers of different diameters, this utility model provides a laser strengthening device, the specific technical solution of which is as follows:

Combined with the synchronous operation of the laser cladding device, it achieves continuous and automated strengthening of long rollers, reducing the time spent on multiple clamping and adjustment processes. Through uniform and stable laser cladding, the roller surface acquires a coating with excellent wear resistance, corrosion resistance, and fatigue resistance, extending the roller's service life and significantly reducing the frequency of equipment maintenance and component replacement.

[0029] like Figure 1 As shown in Figure 2, a laser strengthening device according to one embodiment of the present invention includes a frame 1, a laser cladding device 2, a rotating base 3, and a driving device 4. The laser cladding device 2 is mounted on the frame 1 and is used to cover the surface of the rollers of the rolling machine with a coating material. The rotating base 3 is mounted on the frame 1 and rotatably connected to the frame 1. The rotating base 3 is provided with an opening 5 and a plurality of clamping mechanisms 6. The opening 5 is used for the rollers to pass through, and the plurality of clamping mechanisms 6 cooperate to clamp and convey the rollers. The driving device 4 is mounted on the frame 1, and the output end of the driving device 4 is connected to the rotating base 3 for transmission. The driving device 4 is used to drive the rotating base 3 to rotate.

[0030] The aforementioned laser strengthening equipment, through the ingenious cooperation between the drive device 4 and the rotating base 3, enables the rollers to rotate continuously and stably. Combined with the synchronous operation of the laser cladding device 2, it achieves continuous automated strengthening of long rollers, reducing the time spent on multiple clamping and adjustment processes. Through uniform and stable laser cladding, the roller surface acquires a coating with excellent wear resistance, corrosion resistance, and fatigue resistance, extending the roller's service life and significantly reducing equipment maintenance and component replacement frequency. This laser strengthening equipment solves the problem of traditional equipment being unable to adapt to rollers of different diameters.

[0031] like Figure 1As shown in Figure 2, in one embodiment, the laser cladding device 2 includes a first linear module 21, a second linear module 22, and a laser head 23. The first linear module 21 is mounted on the frame 1, and the second linear module 22 is mounted on the moving end of the first linear module 21. The laser head 23 is mounted on the moving end of the second linear module 22. The first linear module 21 drives the laser head 23 to move horizontally, and the second linear module 22 drives the laser head 23 to move closer to and away from the opening 5. Thus, by setting the first linear module 21 and the second linear module 22 perpendicular to each other, the laser head 23 is given precise movement capabilities in both the horizontal and vertical directions. The first linear module 21 enables the laser head 23 to feed along the roller axis, ensuring that the coating covers the entire length; the second linear module 22 precisely controls the working distance between the laser head 23 and the roller surface, ensuring optimal utilization of laser energy and stability of cladding quality.

[0032] like Figure 1 As shown in Figure 2, in one embodiment, the clamping mechanism 6 includes a third linear module 61 and an electric roller 62. The third linear module 61 is mounted on the rotating base 3, and the electric roller 62 is mounted on the moving end of the third linear module 61. The third linear module 61 is used to drive the electric roller 62 away from and towards the opening 5. Thus, by using a third linear module 61 to drive the electric roller 62 in each clamping mechanism 6, multiple clamping points can be simultaneously adjusted with high precision. This design enables a single device to reliably clamp and transport rollers of different diameters, greatly enhancing the versatility and adaptability of the equipment. The electric roller 62 not only provides clamping force but also actively drives the roller movement.

[0033] like Figure 1As shown in Figure 2, in one embodiment, the outer contour of the rotating base 3 is annular, and a groove is provided inside the rotating base 3; the driving device 4 includes a slide rail 41 and a driving structure; the outer contour of the slide rail 41 is annular, and the rotating base 3 is sleeved on the slide rail 41; the slide rail 41 is inserted into the groove and slidably connected to the groove, and a connecting block 42 is provided on the slide rail 41, the connecting block 42 being connected to the frame 1; the driving structure includes a first transmission wheel 43, a second transmission wheel 44, a third transmission wheel 45, a belt 46, and a first driving block; the first transmission wheel 43, the second transmission wheel 44, the third transmission wheel 45, a belt 46, and a first driving block; the first transmission wheel 43, the second transmission wheel 44, the third transmission wheel 45, the belt 46, and the first driving block; Both wheel 44 and the third transmission wheel 45 are mounted on the frame 1 and rotatably connected to it. A belt 46 is fitted onto the first transmission wheel 43, the second transmission wheel 44, and the third transmission wheel 45. The first drive block is mounted on the frame 1, and its output end is connected to the third transmission wheel 45. The first drive block drives the third transmission wheel 45 to rotate. The first transmission wheel 43 and the second transmission wheel 44 are slidably connected to the rotating base 3. The first transmission wheel 43, the second transmission wheel 44, the third transmission wheel 45, the belt 46, and the first drive block cooperate to drive the rotating base 3 to rotate. Thus, through the sliding cooperation between the annular rotating base 3 and the matching annular slide rail 41, an extremely stable and smoothly rotating support platform is formed, ensuring the stability and concentricity of the rollers during high-speed rotation.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
