[0002] The rolling mill is a main working component and tool used to induce continuous plastic deformation in metal. The rolling mill roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. After the rolling mill roll is formed, appropriate equipment is needed for surface treatment.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please see Figures 1-4 This invention provides a technical solution: a surface treatment device for producing rolls, including a base 1, with uprights 4 on both sides of the base 1, and a roll 2 horizontally and rotatably mounted between the two uprights 4. The two ends of the roll 2 are fixed by grippers on the inner surface of the uprights 4, and the left end of the roll 2 is connected to an external motor. A side grinding adjustment mechanism 3 is provided between the two uprights 4 and located above the roll 2. The side grinding adjustment mechanism 3 can be used to grind the shaft diameter of the roll 2, and the tilt grinding angle of the grinding roller 322 can be adjusted as needed to increase the comprehensiveness and range of grinding of the roll 2 and improve the grinding efficiency of the roll 2. The side grinding adjustment mechanism 3 includes two side grinding components 32 located opposite each other at the shaft diameter of the roll 2 and grinding them. The two side grinding components 32 can grind the shaft diameter at both ends of the roll 2 at the same time. An angle adjustment component 31 for driving the side grinding component 32 to rotate is provided on the rear surface of the side grinding component 32 to adjust the grinding angle of the grinding roller 322.

[0028] The side grinding component 32 includes a grinding roller 322 that is inclined at the shaft diameter of the roller component 2. A drive motor 324 is provided at the inclined upper end of the grinding roller 322 to drive it to rotate. The drive motor 324 drives the grinding roller 322 to rotate, thereby allowing the outer surface of the grinding roller 322 to grind the inclined shaft diameter.

[0029] In this embodiment, preferably, the angle adjustment component 31 includes a lower vertical plate 316 horizontally positioned above the roll 2. By providing the angle adjustment component 31, the angle between the side grinding component 32 and the horizontal direction can be changed through the rotatable connection between the rotating plates, thereby changing the angle of the grinding roller 322. This facilitates the grinding roller 322 to better conform to the inclined surface of the shaft diameter, increasing the convenience of grinding the shaft diameter surface. An upper vertical plate 311 is provided above the lower vertical plate 316, and upper rotating plates 312 are rotatably mounted on the front surfaces of both ends of the upper vertical plate 311. The up-and-down movement can drive the upper rotating plate 312 to rotate. The lower end of the upper rotating plate 312 is rotatably provided with a lower rotating plate 313. The lower end of the lower rotating plate 313 is provided with a fixed plate 315. The lower end of the fixed plate 315 faces inward, so that the side grinding component 32 installed on it faces inward. The front surface of the fixed plate 315 is provided with the side grinding component 32. A support column 314 is provided between the middle of the lower rotating plate 313 and the lower upright plate 316, so that the lower rotating plate 313 can rotate around the support column 314, which provides support and limits the position of the lower rotating plate 313.

[0030] In this embodiment, preferably, the side grinding component 32 further includes an adjusting cylinder 321 horizontally arranged on the front surface of the fixing plate 315. The adjusting cylinder 321 can be used to change the distance between the two grinding rollers 322 with relative positions, so that the grinding rollers 322 can grind the shaft diameter. The adjusting rod inside the adjusting cylinder 321 is provided with a mounting frame 323. The positions of the mounting frame 323 and the grinding rollers 322 can move with the adjustment rod. The inner surface of the mounting frame 323 is provided with a drive motor 324. The diameter of the grinding rollers 322 is larger than the width of the mounting frame 323, so that the circumferential surface of the grinding rollers 322 can grind the shaft diameter.

[0031] In this embodiment, preferably, a lifting component 35 is provided on the rear side of the upper plate 311. The lifting component 35 can drive the upper plate 311 to move downward, which facilitates subsequent changes in the angle rotation of the side grinding component 32. The lifting component 35 includes a working motor 352 fixed on the rear surface of the lower plate 316. A fixing nut block 353 located above the working motor 352 is provided on the rear surface of the upper plate 311. As the working motor 352 works, it can drive the drive screw 351 to rotate, and the fixing nut block 353 moves upward or downward as the drive screw 351 rotates. The upper end of the working motor 352 is vertically provided with a drive screw 351 that passes through the fixing nut block 353. A limiting rod that moves through the upper plate 311 is provided on the upper surface of the lower plate 316, which can limit the position of the upper plate 311 and prevent it from rotating.

[0032] In this embodiment, preferably, a lifting cylinder is embedded inside the upright frame 4. The upper end of the lifting rod inside the lifting cylinder is fixed to the outer end of the fixed frame 33. The lifting cylinder can drive the fixed frame 33 to move and change its height, thereby driving the subsequent side grinding component 32 to change its grinding height. A screw is rotatably arranged between the two upright frames 4. A machine base is screwed on the screw. The movement of the machine base does not affect the side grinding adjustment mechanism 3. An external motor and a grinding wheel 5 for grinding the surface of the roll 2 are arranged on the front surface of the machine base.

[0033] In summary, during the grinding of the 2nd shaft diameter of the roll component, the working motor 352 operates, driving the drive screw 351 to rotate. This causes the upper vertical plate 311 to move downwards along the drive screw 351, and the upper rotating plate 312 moves accordingly, rotating outwards at its lower end. Meanwhile, the upper rotating plate 313 rotates outwards at its upper end and inwards at its lower end, causing the side grinding component 32 to rotate. This changes the angle between the grinding roller 322 in the side grinding component 32 and the vertical direction. When the grinding angle of the grinding roller 322 is appropriate, the adjusting cylinder 321 operates, and the internal adjusting rod extends, allowing the two grinding rollers 322 to move relative to each other simultaneously. As the roller moves, the distance between the two gradually shortens, and the grinding roller 322 approaches the shaft diameter of the roller 2. At the same time, the lifting cylinder works, and the lifting rod inside the lifting cylinder retracts downward, which can drive the fixed frame 33 to move downward. The drive motor 324 works, driving the grinding roller 322 to rotate. When the grinding roller 322 contacts the rotating shaft diameter of the roller 2, the grinding roller 322 is used to grind the surface of the shaft diameter. During this process, the grinding wheel 5 can simultaneously grind the circumferential surface of the roller 2, increasing the uniformity and grinding effect of the grinding treatment on the outer surface of the roller 2, and improving the grinding efficiency of the roller 2.

[0034] Example 2

[0035] Reference Figure 5 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0036] In this embodiment, preferably, a fixed frame 33 is provided between the upper surfaces of the two uprights 4, and a telescopic member 34 is provided between the rear side of the lower upright plate 316 and the fixed frame 33. Using the telescopic member 34, the position of the grinding roller 322 in the Y-axis direction can be adjusted according to the size of the roller component 2, so that the grinding roller 322 is in a suitable grinding position, improving the grinding range and adaptability of the roller component 2. The telescopic member 34 includes two guide rails 341 fixed to the upper surface of the fixed frame 33 and distributed along the Y-axis direction. The guide rails 341 have a T-shaped cross-section and connect... A sliding sleeve is provided on the lower surface of plate 342. While the sliding sleeve and guide rail 341 slide back and forth, it is not easy for them to separate vertically. A synchronization plate is provided between the two sliding sleeves. A connecting plate 342 with its front end fixed to the rear surface of the lower upright plate 316 is slidably sleeved on the guide rail 341. A telescopic cylinder 343 is provided between the two connecting plates 342. A stabilizing frame 344 is provided between the telescopic cylinder 343 and the lower upright plate 316 to increase the installation and use strength of the telescopic cylinder 343. At the same time, the free end of the telescopic rod provided inside the telescopic cylinder 343 is fixed to the surface of the synchronization plate.

[0037] In summary, when it is necessary to change the position of the grinding roller 322 in the Y-axis direction during use, the telescopic cylinder 343 works. When the telescopic rod inside extends outward, it drives the synchronous plate to move forward, thereby driving the two sliding sleeves to move forward synchronously along the guide rail 341. The lower upright plate 316 is connected to the sliding sleeve through the connecting plate 342. Therefore, the lower upright plate 316 and the side grinding component 32 move forward accordingly, so that the subsequent side grinding component 32 is in a suitable position for grinding the shaft diameter, thereby increasing the grinding range of the surface of the roller 2.

[0038] Example 3

[0039] Reference Figure 6 and Figure 7 This is the third embodiment of the present invention.

[0040] In this embodiment, preferably, a collection mechanism 6 located below the roll 2 is provided on the upper surface of the base 1. The collection mechanism 6 collects the debris generated during the grinding of the roll 2 without affecting its surface grinding, increasing the safety of the roll 2 during rotational grinding. Simultaneously, it allows for further polishing of the outer surface of the roll 2, increasing the convenience and effectiveness of surface treatment. The collection mechanism 6 includes a protective arc plate 62 horizontally located below the roll 2, providing semi-enclosed protection for the roll 2 without affecting the surface grinding process. A collection box 6 is provided between the lower surface of the protective arc plate 62 and the base 1. 1. Two suction components are arranged opposite to each other between the inner arc surface of the protective arc plate 62 and the roll 2. The suction components include a connecting main pipe 63 horizontally installed on the inner arc surface of the protective arc plate 62. Suction pipes 65 are evenly distributed on the surface of the connecting main pipe 63. The suction pipes 65 are close to the surface of the roll 2 and suck the residual debris on its surface into the feeding pipe 64. The lower end of the suction pipe 65 is connected to the air pump installed in the collection box 61. The inner surface of the connecting main pipe 63 is provided with a feeding pipe 64 extending into the collection box 61. A filter screen is horizontally arranged inside the collection box 61 to facilitate the discharge of the gas fed into the collection box 61. At the same time, the debris mixed in the gas is retained in the collection box 61.

[0041] In this embodiment, preferably, polishing components 66 are arranged opposite to each other on the front and rear surfaces of the protective arc plate 62. The polishing components 66 can be used to further polish the circumferential surface of the milled roller 2. The distance between the polishing roller 662 and the roller 2 is adjustable. The outer surface of the polishing roller 662 is a polishing sand surface. The polishing component 66 includes a polishing roller 662 horizontally located outside the roller 2. A support plate 661 is provided at the outer end of the polishing roller 662. The support plate 661 supports the polishing roller 662. Fixed long plates 663 located outside the support plate 661 are provided on the outer surfaces of both ends of the protective arc plate 62. The fixed long plates 663 have multiple through holes along their length direction. The two are connected and fixed by connecting bolts 664. The connecting bolts 664 can realize the detachable connection between the fixed long plates 663 and the support plate 661.

[0042] In summary, during the grinding process of the roll 2, the generated debris adheres to the surface of the roll 2. At this time, the air pump works, generating suction force to draw the gas and debris mixed in the gas from the suction pipe 65 into the collection box 61. The gas is discharged outward through the filter screen, while the debris is filtered into the collection box 61. During the debris collection process, the connecting bolt 664 can be removed to adjust the distance between the support plate 661 and the fixed long plate 663, thereby changing the position between the polishing roller 662 and the roll 2. When the position is appropriate, the connecting bolt 664 is used to fix the position of the support plate 661 and the fixed long plate 663 again. As the roll 2 rotates, the polishing roller 662 further polishes the surface of the roll 2, increasing the comprehensiveness and convenience of the grinding process. At the same time, the protective arc plate 62 provides semi-enclosed protection for the roll 2 throughout the process, increasing the stability and safety of the surface treatment of the roll 2.

[0043] Example 4

[0044] This embodiment is obtained by combining Embodiment 1, Embodiment 2 and Embodiment 3.

[0045] During use, the circumferential surface of the roll 2 is polished by the grinding wheel 5. During this process, the angle adjustment component 31 is used to adjust the operating angle of the two grinding rollers 322. When the angle is appropriate, the distance between the two grinding rollers 322 can be adjusted by the adjusting cylinder 321 to facilitate the adaptation of the shaft diameter position. At the same time, according to the size of the roll 2, the position of the grinding rollers 322 in the Y-axis direction can be changed by the telescopic component 34 to increase the grinding range of the grinding rollers 322 on the shaft diameter of the roll 2. While grinding, the suction component is used to suck up the debris generated by the grinding of the surface of the roll 2 and send it into the collection box 61. The polishing component 66 can further polish the surface of the roll 2 to improve the grinding effect of the surface of the roll 2.
