Description

Technical Field

[0001] This invention relates to the field of roll grinding technology, and specifically to a novel roll grinding machine for processing. Background Technology

[0002] Roll grinding machines are metal cutting machine tools that repair or improve the surface quality, dimensional accuracy, and geometry of rolls through grinding processes. They are key equipment in industries such as metallurgy and machinery manufacturing to ensure the quality and production efficiency of rolled products. In the grinding and repair process of rolls, the rolls are first installed on the headstock and tailstock of the machine tool. The headstock spindle uses servo motor direct drive technology to drive the rolls to rotate on the machine tool. Then, coarse-grit grinding wheels are used to quickly remove defects such as fatigue layers, cracks, oxide scale, severe wear, or corrosion from the roll surface, initially correcting the roll geometry (such as roundness and cylindricity) to provide a foundation for fine grinding. Finally, fine-grit grinding wheels are used to further correct the dimensional accuracy of the rolls and reduce surface roughness so that the repaired rolls meet the rolling process requirements. First, coarse grinding quickly removes a large amount of material, shortening the processing time and avoiding excessive wear of the grinding wheel or surface burning due to excessive cutting during the fine grinding stage. Then, fine grinding is performed on the basis of coarse grinding to perform micro-cutting, ensuring dimensional accuracy and surface quality, reducing the number of repeated grinding operations, and improving processing efficiency.

[0003] Currently, in the process of grinding and repairing the surface of rolling mill rolls, a rotating grinding wheel is usually used to grind the surface of the rolling mill rolls. When the grinding wheel rubs against the rolling mill roll at high speed, the rolling mill roll material is cut into tiny particles. These tiny particles are easy to soften and adhere to the surface of the grinding wheel under high temperature, clogging the pits on the surface of the grinding wheel. After the grinding wheel is clogged, the abrasive grains on the surface of the grinding wheel are covered with abrasive debris, which prevents the abrasive grains from effectively cutting the workpiece, causing the surface shape of the grinding wheel to be distorted, and thus affecting the dimensional accuracy and surface quality of the rolling mill rolls. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the prior art, the present invention provides a novel roll grinding machine for processing, which can effectively solve the problems in the background art.

[0006] Furthermore, the telescopic element includes a telescopic cylinder and a telescopic rod. The bottom end of the telescopic cylinder is fixedly connected to the top of the machine base, the telescopic rod is slidably connected inside the telescopic cylinder, the top end of the telescopic rod is fixedly connected to the lifting frame, and a telescopic spring is fixedly connected between the telescopic cylinder and the telescopic rod.

[0007] Furthermore, a first motor is fixedly connected to the top of the machine platform, a screw is rotatably connected to the top of the machine platform, a slide rod is fixedly connected to the top of the machine platform, a sliding frame is slidably sleeved on the outer circumference of the slide rod, the sliding frame is threadedly sleeved on the outer circumference of the screw, and the output shaft of the first motor is fixedly connected to the screw.

[0008] Furthermore, a rotating circular block is fixedly connected to the bottom of the rotating square plate, the rotating circular block is rotatably connected to the sliding frame, an adjusting plate is fixedly connected to the bottom end of the rotating circular block, an adjusting circular block is rotatably connected to the bottom end of the adjusting plate, an adjusting guide rail is fixedly connected to the top of the machine base, and the adjusting circular block is slidably connected inside the adjusting guide rail.

[0009] Furthermore, the adjusting guide rail includes a horizontal rail, a left longitudinal rail, and a right longitudinal rail. One end of the horizontal rail is connected to the left longitudinal rail, and the other end of the horizontal rail is connected to the right longitudinal rail.

[0010] Furthermore, a second motor is fixedly connected to the outer surface of the mounting plate, an elliptical plate is fixedly connected to the outer circumference of the main shaft, a lifting wheel is rotatably connected to the top of the inner wall of the lifting frame, the lifting wheel contacts the top of the elliptical plate, and the output shaft of the second motor is fixedly connected to the main shaft.

[0011] Furthermore, a mounting bracket is fixedly connected to the top of the rotating square plate, a rotating rod is rotatably connected to the inner wall of the mounting bracket, a swing rod is fixedly connected to the outer circumference of the rotating rod, a U-shaped connecting rod is fixedly connected to the outer circumference of the rotating rod, a pushing block is slidably connected inside the mounting bracket, a pushing groove is formed on the outer surface of the pushing block, the U-shaped connecting rod is slidably connected to the pushing groove, and a pushing wheel is rotatably connected to the top of the pushing block.

[0012] Furthermore, the bottom of the placement rack is fixedly connected to a fixed guide rail, which includes a straight rail and a corrugated rail.

[0013] Furthermore, a mounting frame is fixedly connected to the top of the rotating square plate, an extrusion cylinder is slidably connected to the inner wall of the mounting frame, an extrusion rod is slidably connected inside the extrusion cylinder, a return spring is fixedly connected between the extrusion rod and the extrusion cylinder, and an extrusion arc plate is fixedly connected to the end of the extrusion rod away from the extrusion cylinder.

[0014] Furthermore, an extrusion wheel is rotatably connected to the outer circumference of the rotating rod, and an extrusion plate is fixedly connected to the outer circumference of the extrusion cylinder.

[0015] The technical solution provided by this invention has the following advantages compared with the prior art: 1. This invention, by setting a magnetic cylinder to rotate around the main shaft, when the grinding wheel contacts the magnetic cylinder, the metal shavings stuck in the small pits on the surface of the grinding wheel are gradually attracted to the outer circumference of the magnetic cylinder under the magnetic attraction. This effectively achieves continuous cleaning of the metal shavings stuck in the pits on the grinding surface of the grinding wheel, preventing the metal shavings from adhering to the small pits on the grinding wheel surface and causing clogging. As a result, the cleanliness of the grinding wheel surface is improved during the grinding process of the roll surface, so that the abrasive grains on the grinding wheel surface can effectively grind the roll, avoid the distortion of the surface shape of the grinding wheel, and thus improve the dimensional accuracy and surface quality of the roll.

[0016] 2. This invention uses an elliptical plate rotating around a main shaft to drive a lifting frame and a brush plate in reciprocating motion. The flexible brushes in the brush plate extend into the recesses on the surface of the rotating grinding wheel and come into contact with the grinding debris clogging inside. This disturbs the grinding debris, making it easier for the debris in the clogged recesses to loosen and detach from the recesses on the grinding wheel surface under the magnetic attraction of the magnetic cylinder. Furthermore, with the grinding wheel as a reference, the moving brush plate moves not only vertically but also horizontally relative to the grinding wheel. By "secondary disturbance" of the grinding debris clogging the recesses on the grinding wheel surface in different directions, the moving brush plate, through multi-dimensional mechanical action, makes it easier for the clogged grinding debris to loosen and be attracted to the surface by the magnetic cylinder, significantly improving the cleaning quality and efficiency of cleaning the grinding debris clogging the grinding wheel surface.

[0017] 3. This invention achieves periodic tapping of the grinding wheel by setting the reciprocating sliding of the pushing block. At the same time, the magnetic cylinder adsorbs the grinding debris on the outer circumference of the grinding wheel. Under this tapping action, the shock wave and vibration energy generated by the tapping are used to break the adhesion strength between the grinding debris and the grinding wheel, further improving the loosening effect on the grinding debris clogging the pits. This helps to loosen the stubborn grinding debris embedded in the pits and further improves the cleaning effect on the grinding wheel surface.

[0018] 4. This invention adaptively adjusts the pressure applied to the grinding wheel by the extrusion arc plate, thereby effectively preventing the grinding wheel from separating from the magnetic cylinder due to vibration caused by the impact of the swing rod when the grinding wheel is struck. This ensures that the magnetic cylinder, used to clean the grinding debris clogging the pits on the grinding wheel surface, remains in close contact with the cleaning surface of the grinding wheel, thus guaranteeing good contact between the grinding wheel and the magnetic cylinder, ensuring the magnetic cylinder's adsorption and cleaning strength for grinding debris, and ensuring the grinding wheel's processing effect on the roller surface.

[0019] 5. This invention adaptively adjusts the pressure applied to the grinding wheel by the extrusion arc plate, thereby applying a large extrusion force to the grinding wheel when the swing rod strikes it. Under this extrusion force, the grinding wheel and the magnetic cylinder maintain good contact. As the swing rod gradually separates from the grinding wheel, the extrusion force applied to the grinding wheel by the extrusion arc plate decreases, and the contact pressure between the grinding wheel and the magnetic cylinder also decreases, thereby reducing the friction between the grinding wheel and the magnetic cylinder and extending the service life of the grinding wheel and the magnetic cylinder.

[0035] Working principle: The process of switching between coarse grinding and fine grinding: In practical applications, such as Figure 1 As shown, the roll to be repaired is mounted on the headstock control system 11, which uses servo motor direct drive technology and high-precision encoder to achieve closed-loop speed control, thereby driving the roll to rotate above the machine base 1. Figure 1 and Figure 7 As shown, the first grinding wheel 14 is driven to rotate rapidly on the rotating square plate 13 by the grinding wheel control system, as... Figure 1 and Figure 6 As shown, by starting the first motor 3, the first motor 3 drives the screw 31 to rotate forward at the top of the machine base 1 via the output shaft. Since the sliding frame 12 is slidably sleeved on the outer circumferential surface of the sliding rod 32 and threadedly sleeved on the outer circumferential surface of the screw 31, the rotating screw 31 drives the sliding frame 12 on its outer circumferential surface to move along the axis of the sliding rod 32 toward the left end of the machine base 1 (see reference). Figure 1 ), and then combine Figure 13 , Figure 14 and Figure 15It can be seen that during the movement of the sliding frame 12 along the axis of the slide rod 32, the sliding frame 12 drives the rotating square plate 13 at its top to move along the axis of the slide rod 32. The rotating square plate 13 drives the rotating circular block 4 at its bottom to move along the axis of the slide rod 32. The rotating circular block 4 drives the adjusting plate 41 at its bottom to move along the axis of the slide rod 32. The adjusting plate 41 drives the adjusting circular block 42 at its bottom to move along the axis of the slide rod 32, causing the adjusting circular block 42 to move to the left along the horizontal rail 431 (refer to...). Figure 15 Therefore, under the limiting effect of the horizontal rail 431 on the adjusting block 42, the rotating block 4 and the rotating square plate 13 cannot rotate around the axis of the rotating block 4. The rotating square plate 13 and the sliding frame 12 remain relatively stationary. The sliding frame 12 drives the rotating square plate 13 above it to move synchronously along the axis of the sliding rod 32. The rotating square plate 13 drives the first grinding wheel 14 and the second grinding wheel 15 on its top to move to the left along the axis of the sliding rod 32 (see reference). Figure 1 and Figure 9 In this process, the moving first grinding wheel 14 contacts the rotating roll, while the moving second grinding wheel 15 does not contact the rotating roll. The first grinding wheel 14 performs rough grinding on the surface of the roll, quickly removing defects such as fatigue layer, cracks, oxide scale, severe wear, and corrosion from the surface of the roll. The grinding depth is relatively deep, improving the material removal rate, so as to initially correct the geometry of the roll (such as roundness and cylindricity), providing a basis for fine grinding. After the first grinding wheel 14 finishes its rough grinding operation on the rollers, the rotating square plate 13 continues to drive the first grinding wheel 14 and the second grinding wheel 15 to move to the left along the axis of the slide bar 32 (see reference). Figure 1 and Figure 9 This causes the first grinding wheel 14 to separate from the initially ground roller, as the sliding frame 12 continues to move to the left (see reference). Figure 13 , Figure 14 , Figure 15 and Figure 16 The sliding frame 12 drives the rotating block 4 to move along the axis of the sliding rod 32. The rotating block 4, through the adjusting plate 41, drives the adjusting block 42 to move along the horizontal rail 431 to the left of the vertical rail 432. After the adjusting block 42 moves to the left end of the horizontal rail 431 (refer to...), Figure 16 As the rotating block 4 continues to move to the left, the rotating block 4, through the adjusting plate 41, drives the adjusting block 42 to move upward along the left longitudinal rail 432 (see reference). Figure 16 After the adjusting block 42 moves to the top of the left longitudinal rail 432 (refer to...), Figure 17 As the rotating block 4 continues to move to the left, the rotating block 4, through the adjusting plate 41, drives the adjusting block 42 to move downward along the left longitudinal rail 432 (see reference). Figure 18 During this process, the circular block 42 is adjusted to move upwards and then downwards along the left longitudinal rail 432 (see reference). Figure 16 , Figure 17and Figure 18 This allows the adjusting block 42 to rotate 180 degrees around the axis of the rotating block 4. The adjusting block 42 drives the adjusting plate 41, the rotating block 4, and the rotating square plate 13 to rotate 180 degrees around the axis of the rotating block 4. The rotating square plate 13 drives the first grinding wheel 14 and the second grinding wheel 15 on its top to rotate 180 degrees around the axis of the rotating block 4, so as to realize the mutual switching between the positions of the first grinding wheel 14 and the second grinding wheel 15 (the first grinding wheel 14 is located on the side above the sliding frame 12 away from the roller, and the second grinding wheel 15 is located on the side above the sliding frame 12 closer to the roller). By controlling the first motor 3 to drive the screw 31 to rotate in the opposite direction, the screw 31 drives the sliding frame 12 to move along the axis of the sliding rod 32 toward the right end of the machine base 1 (reference). Figure 1 ), and then combine Figure 13 and Figure 18 It can be seen that during the movement of the sliding frame 12 along the axis of the slide rod 32, the sliding frame 12 drives the rotating block 4 to move along the axis of the slide rod 32. The rotating block 4 drives the adjusting block 42 to move along the horizontal rail 431 to the right longitudinal rail 433 through the adjusting plate 41. Under the limiting action of the horizontal rail 431 on the adjusting block 42, the rotating block 4 and the rotating square plate 13 cannot rotate around the axis of the rotating block 4. The rotating square plate 13 and the sliding frame 12 remain relatively stationary. The sliding frame 12 drives the rotating square plate 13 above it to move synchronously along the axis of the slide rod 32. The rotating square plate 13 drives the first grinding wheel 14 and the second grinding wheel 15 on its top to move to the right along the axis of the slide rod 32 (reference). Figure 1 During this process, the moving second grinding wheel 15 contacts the rotating roll, while the moving first grinding wheel 14 does not contact the rotating roll. The second grinding wheel 15 performs fine grinding on the surface of the roll to further correct the dimensional accuracy of the roll, reduce the surface roughness of the roll, and eliminate the processing marks left by rough grinding, so that the repaired roll meets the rolling process requirements. In summary, after the second grinding wheel 15 finishes its fine grinding operation on the rolls, the rotating block 4 drives the adjusting block 42 to move upward and then downward along the right longitudinal rail 433 (see reference). Figure 18 This allows for the switching of positions between the first grinding wheel 14 and the second grinding wheel 15 (the first grinding wheel 14 is located on the side above the sliding frame 12 closer to the roll, and the second grinding wheel 15 is located on the side above the sliding frame 12 away from the roll). As the sliding frame 12 drives the rotating square plate 13 above it to reciprocate along the axis of the sliding rod 32, the positions of the first grinding wheel 14 and the second grinding wheel 15 are automatically switched. The first grinding wheel 14 and the second grinding wheel 15 alternately perform the grinding operation on the roll to complete the segmented grinding operation of the roll (first rough grinding, then fine grinding).

[0036] The grinding wheel cleaning process: In practical applications, such as Figure 1 , Figure 4 and Figure 5 As shown, during the movement of the sliding frame 12 along the axis of the sliding rod 32, the rotating square plate 13 drives the first grinding wheel 14 above it to grind the roller. During this process, the second grinding wheel 15 is located above the rotating square plate 13, near the magnetic cylinder 22. By starting the second motor 5, the second motor 5 drives the main shaft 21 to rotate on the mounting plate 2 via its output shaft. The main shaft 21 drives the magnetic cylinder 22 on its outer circumference to rotate around the axis of the main shaft 21. When the rotating square plate 13 drives the second grinding wheel 15 to contact the magnetic cylinder 22, the magnetic field generated by the magnetic cylinder 22 penetrates the surface pits of the second grinding wheel 15, dislodging the adhering metal... The grinding debris is magnetized under the action of the magnetic field, generating a magnetic moment in the same direction as the magnetic field of the magnetic cylinder 22. This causes it to be attracted to the outer circumference of the magnetic cylinder 22. As the second grinding wheel 15 rotates, its outer circumference contacts one side of the magnetic cylinder 22, completely cleaning the metal grinding debris clogging the grinding surface of the second grinding wheel 15. This improves the cleanliness of the second grinding wheel 15 surface during the grinding process of the roll, allowing the abrasive grains on the second grinding wheel 15 to effectively grind the roll, preventing surface shape distortion of the second grinding wheel 15, and thus improving the dimensional accuracy and surface quality of the roll. Furthermore, as... Figure 2 As shown, by controlling the magnetic cylinder 22 to rotate around the axis of the main shaft 21, the magnetic cylinder 22 drives the metal abrasive adsorbed on its surface to rotate towards the collection box 24. Since one side of the collection box 24 is tangent to the outer circumference of the magnetic cylinder 22, the magnetic cylinder 22 drives the metal abrasive adsorbed on it to move into the interior of the collection box 24, so as to ensure the cleanliness of the outer circumference of the magnetic cylinder 22 and prevent the excessive metal abrasive on the surface of the magnetic cylinder 22 from affecting the cleaning effect of the magnetic cylinder 22 on the second grinding wheel 15. As a further embodiment of the present invention, such as Figure 4 and Figure 5As shown, by controlling the second motor 5 to drive the main shaft 21 to rotate, the main shaft 21 drives the elliptical plate 51 on its outer circumference to rotate around the axis of the main shaft 21. The elliptical plate 51 pushes the lifting wheel 52 upward through its arc surface. Under the guidance of the telescopic element 25, the lifting wheel 52 drives the lifting frame 26 to move upward along the axis of the telescopic cylinder. After the elliptical plate 51 rotates ninety degrees, under the action of the lifting frame 26's own weight and the elastic force of the telescopic spring, the lifting frame 26 moves downward along the axis of the telescopic cylinder. In this way, as the elliptical plate 51 continues to rotate, the lifting frame 26 reciprocates up and down along the axis of the telescopic cylinder. The lifting frame 26 drives the brush plate 27 on its outer surface to reciprocate up and down along the axis of the telescopic cylinder. During the process of the rotating square plate 13 driving the second grinding wheel 15 to contact the brush plate 27, the up-and-down moving brush plate 27 is located at the second grinding wheel 15. The brush plate 27 "brushes" the outer circumference of the second grinding wheel 15 from one side. The flexible brush in the brush plate 27 extends into the pits on the surface of the rotating second grinding wheel 15 and comes into contact with the grinding debris stuck inside. This disturbs the grinding debris, making it easier for the grinding debris in the pits to loosen and detach from the pits on the surface of the second grinding wheel 15 under the magnetic attraction of the magnetic cylinder 22. Furthermore, with the second grinding wheel 15 as a reference, the moving brush plate 27 moves not only vertically but also horizontally relative to the second grinding wheel 15. The moving brush plate 27 "disturbs" the grinding debris stuck in the pits on the surface of the second grinding wheel 15 in different directions. With the help of multi-dimensional mechanical action, the grinding debris is more easily loosened and attracted to the surface by the magnetic cylinder 22, which significantly improves the cleaning quality and efficiency of the grinding debris stuck on the surface of the second grinding wheel 15. As a further embodiment of the present invention, such as Figure 1 and Figure 6 As shown, during the rotation of the square plate 13, which drives the second grinding wheel 15 at its top to move along the axis of the slide bar 32, the square plate 13 drives the mounting bracket 6 at its top to move along the axis of the slide bar 32. The mounting bracket 6 drives the push block 64 and push wheel 65 inside it to move along the axis of the slide bar 32, so that the push wheel 65 enters the interior of the fixed guide rail 7 along the straight rail 71. As the push wheel 65 moves from the straight rail 71 to the corrugated rail 72, the push block 64 cannot slide inside the mounting bracket 6 due to the limiting effect of the straight rail 71. After the push wheel 65 enters the interior of the corrugated rail 72, the push wheel 65 drives the push block 64 at its bottom to slide back and forth inside the mounting bracket 6 due to the limiting effect of the corrugated rail 72. Furthermore, the push block 64 above the second grinding wheel 15 slides back and forth inside the mounting bracket 6, while the push block 64 above the first grinding wheel 14 remains stationary inside the mounting bracket 6. When the moving push block 64 approaches the first grinding wheel 14, as... Figure 7 and Figure 8As shown, the push block 64 pushes the U-shaped connecting rod 63 to rotate around the axis of the rotating rod 61 through its internal push groove. The U-shaped connecting rod 63 drives the rotating rod 61 at its bottom to rotate around the axis of the rotating rod 61. The rotating rod 61 drives the swing rod 62 on its outer circumference to rotate downward around the axis of the rotating rod 61, so that the bottom end of the swing rod 62 strikes the outer circumference of the second grinding wheel 15. When the moving push block 64 approaches the second grinding wheel 15, the swing rod 62 rotates upward around the axis of the rotating rod 61. The swing rod 62 and the second grinding wheel... 15 Separation: As the pushing block 64 slides back and forth, the swing rod 62 periodically strikes the second grinding wheel 15. At the same time, the magnetic cylinder 22 adsorbs the grinding debris on the outer circumference of the second grinding wheel 15. Under this striking action, the shock wave and vibration energy generated by the striking action are used to break the adhesion strength between the grinding debris and the second grinding wheel 15, further improving the loosening effect of the grinding debris clogging the pit. This helps to loosen the stubborn grinding debris embedded in the pit, further improving the cleaning effect of the grinding debris clogging the surface of the second grinding wheel 15. As a further embodiment of the present invention, such as Figure 8 and Figure 9 As shown, during the downward rotation of the rotating rod 61 and the swing rod 62, the rotating rod 61 drives the extrusion wheel 9 on its outer circumference to rotate downward. The extrusion wheel 9 pushes the extrusion plate 91 closer to the second grinding wheel 15 along the axis of the extrusion cylinder 81. The extrusion plate 91 drives the extrusion cylinder 81 at its bottom to move closer to the second grinding wheel 15 along the axis of the extrusion cylinder 81. The extrusion cylinder 81 compresses the return spring 83 inside it. Figure 11 and Figure 12 As shown, the return spring 83 changes from its natural state to a compressed state. In the compressed state, the return spring 83 applies pressure to the extrusion arc plate 84 through the extrusion rod 82, causing the extrusion arc plate 84 to apply pressure to the connecting shaft of the second grinding wheel 15. Under this pressure, the second grinding wheel 15 maintains stable contact with the magnetic cylinder 22, preventing the second grinding wheel 15 from being separated from the magnetic cylinder 22 due to vibration caused by the impact of the swing rod 62. This ensures that the magnetic cylinder 22, which is used to clean the grinding debris stuck in the pits on the surface of the second grinding wheel 15, can always be in close contact with the cleaning surface of the second grinding wheel 15, thereby ensuring good contact between the second grinding wheel 15 and the magnetic cylinder 22. This, in turn, ensures the adsorption and cleaning strength of the magnetic cylinder 22 on the grinding debris, and ensures the processing effect of the second grinding wheel 15 on the surface of the roll. As a further embodiment of the present invention, such as Figure 8 , Figure 10 , Figure 11 and Figure 12As shown, during the upward rotation of the rotating rod 61 and the swing rod 62, the rotating rod 61 drives the extrusion wheel 9 to rotate upward. Under the elastic action of the return spring 83, the return spring 83 pushes the extrusion cylinder 81 to move closer to the first grinding wheel 14 along the axis of the extrusion cylinder 81, so that the return spring 83 changes from the compressed state to the natural state, reducing the extrusion arc plate 84's extrusion effect on the second grinding wheel 15. The contact pressure between the second grinding wheel 15 and the magnetic cylinder 22 is also reduced, thereby reducing the friction between the second grinding wheel 15 and the magnetic cylinder 22 and extending the service life of the second grinding wheel 15 and the magnetic cylinder 22. When the rotating square plate 13 drives the second grinding wheel 15 to perform fine grinding on the roll, the magnetic cylinder 22 can be used to perform the same cleaning operation on the surface of the first grinding wheel 14.
