Technical Field

[0002] Cast high-speed steel rolls are new wear-resistant rolls developed in the late 1980s. They have excellent surface hardness and can effectively resist wear under complex rolling conditions. They have excellent wear resistance, which greatly extends their service life. They also have stable high-temperature performance and can still ensure the quality of rolled steel in high-temperature rolling environments. In practical applications, the use of cast high-speed steel rolls can significantly improve the surface quality of steel, reduce roll loss, and reduce the number of roll changes, which is highly compatible with the development trend of high speed, heavy load, high strength, and high precision of rolling mills.

[0003] Surface grinding is a key process in the production of steel rolls. During grinding, the grinding wheel and the roll rub against each other at high speed, generating a large amount of heat instantly. If not cooled in time, the roll will easily have problems such as uneven surface hardness and changes in metallographic structure, which will affect its performance.

[0004] In order to solve these problems, existing grinding equipment needs to be equipped with a lot of cooling and debris handling equipment. For example, cooling equipment often uses large-capacity cooling water tanks and high-power cooling pumps, and is equipped with equipment such as fan bellows, which greatly increases the equipment footprint and significantly increases production costs.

[0020] For further information, see Figure 7 The adjusting assembly 4 includes a screw 7, which is rotatably connected to the grinding machine case 1, and a moving block 8 is threadedly connected to the outer surface of the screw 7. This threaded connection method makes it possible for the moving block 8 to move linearly along the axial direction of the screw 7 when the screw 7 rotates. A sliding rod 11 is fixedly connected to the outside of the moving block 8, and a sliding opening is opened on the side wall of the chip collecting groove 38. The other end of the sliding rod 11 passes through the sliding opening and is equipped with a mounting plate 12. A moving sleeve 13 is installed on the outside of the mounting plate 12. The end of the sliding rod 11 away from the moving block 8 is slidably connected to the inner wall of the chip collecting groove 38. This sliding connection method provides guidance and support for the movement of the sliding rod 11, ensuring that the sliding rod 11 can smoothly drive the moving sleeve 13 to move. The other end of the screw 7 is fixedly connected to a sleeve 9, and a handle 10 is fixedly connected to the outside of the sleeve 9. The sleeve 9 is rotatably connected to the grinding machine case 1. Through this manual adjustment method, the position of the moving sleeve 13 can be accurately controlled to meet the fixing requirements of steel rolling rolls of different specifications.

[0021] For further information, see Figure 4The combined mechanism 5 includes a motor 15, which is mounted on the grinding machine box 1. An extension plate 14 is fixedly mounted inside the chip collecting groove 38. The output end of the motor 15 passes through the extension plate 14 and is fixedly connected to the rotating jacket 16 through a coupling. When the motor 15 is started, the rotation of its output shaft is transmitted to the rotating jacket 16 through the coupling, so that the rotating jacket 16 drives the steel roller fixed thereon to rotate. The rotation of the steel roller cooperates with the grinding action of the grinding component 2, so as to realize the comprehensive grinding of the circumferential surface of the steel roller.

[0022] For further information, please refer to Figure 6 and Figure 8 The output end of the motor 15 is fixedly connected to the left moving wheel 17, and the interior of the chip collecting groove 38 is cut below the chip collecting groove plate 39 and is rotatably connected to the conveying rod 20. One end of the conveying rod 20 is fixedly connected to the lower moving wheel 18. The outsides of the left moving wheel 17 and the lower moving wheel 18 are synchronously provided with a belt 19. The outside of the conveying rod 20 is fixedly connected to a blade 21. The conveying rod 20 and the blade 21 are used to convey the debris. The other end of the conveying rod 20 is rotatably connected to the side wall of the chip collecting groove 38. During the rotation of the conveying rod 20, the blade 21 will push the debris at the bottom of the chip collecting groove 38 and convey it in a specified direction to facilitate subsequent collection and processing.

[0023] In addition, the output end of the motor 15 is fixedly connected to the right moving wheel 23, and the inside of the chip collecting groove 38 is symmetrically rotatably connected to the brush rod 29. One end of the two brush rods 29 is respectively fixedly connected to the small moving wheel 25 and the interlocking wheel 28. The outside of the small moving wheel 25 and the interlocking wheel 28 are synchronously provided with a belt three 27. One side of the small moving wheel 25 is provided with a driven wheel 26. The driven wheel 26 and the outside of the right moving wheel 23 are synchronously provided with a belt two 24. The other ends of the brush rods 29 are rotatably connected to the side walls of the chip collecting groove 38. The rotation of the brush rods 29 can clean some difficult-to-clean parts inside the chip collecting groove 38, and brush off the debris attached to the wall of the chip collecting groove 38, which is convenient for the transportation and collection of the debris.

[0024] Embodiment 2: Figure 2 and Figure 6 As shown, this is a further description of Example 1. In this embodiment, one end of the conveying rod 20 is fixedly connected to an upper gear 30, and the outer part of the upper gear 30 is meshingly connected to a lower gear 31. A cooling pump 32 is installed inside the grinding machine case 1, and the transmission shaft of the cooling pump 32 is fixedly connected to the lower gear 31. When the conveying rod 20 rotates, the upper gear 30 rotates accordingly, and the lower gear 31 is driven to rotate through the gear meshing action, thereby rotating the transmission shaft of the cooling pump 32 and starting the cooling pump 32.

[0025] Specifically, a cooling box 34 is installed on one side of the cooling pump 32, an input pipe 33 is installed on the input end of the cooling pump 32, the input pipe 33 is fixedly connected to the cooling box 34, a hose 35 is fixedly connected to the output end of the cooling pump 32, the other end of the hose 35 is fixedly connected to a nozzle 36, the nozzle 36 is fixedly connected to the grinding component 2, after the cooling pump 32 is started, the coolant in the cooling box 34 is sucked through the input pipe 33, and then transported to the nozzle 36 through the hose 35, and the nozzle 36 sprays the coolant to the grinding part to achieve cooling of the steel roll and the grinding component 2. The setting of the hose 35 allows the nozzle 36 to move flexibly with the movement of the grinding component 2, ensuring the stability of the cooling effect.

[0026] For further information, see Figure 2 and Figure 4 The filter assembly 6 includes a filter box 40, which is installed inside the grinding machine case 1. A first filter screen 41, a second filter screen 42 and filter cotton 43 are installed in the filter box 40 in an inclined manner in sequence. A recovery pipe 37 is installed outside the filter box 40 and at the bottom of the filter cotton 43. The other end of the recovery pipe 37 is fixedly connected and communicated with the cooling box 34. A check valve is installed outside the recovery pipe 37. A conveying groove 22 is opened at the bottom of the chip collecting groove 38 and directly above the filter box 40. The coolant containing debris generated by grinding will flow into the filter box 40 through the conveying groove 22. Debris channels 44 are opened on the side walls of the filter box 40 and above the first filter screen 41, the second filter screen 42 and the filter cotton 43. Drawers 45 are installed outside the multiple debris channels 44 respectively. The mesh of the first filter screen 41 is relatively large, and it is mainly used to filter out larger particles of debris. These larger particles of debris will slide down along the inclined first filter 41, and enter the corresponding drawer 45 through the corresponding debris channel 44 for collection. Then, the coolant continues to flow downward and passes through the second filter 42. The mesh of the second filter 42 is smaller than that of the first filter 41, and can filter out medium-sized particles of debris. Similarly, medium-sized particles of debris will slide down along the second filter 42 and enter the corresponding drawer 45 through the corresponding debris channel 44. Finally, the coolant passes through the filter cotton 43, which can further filter out tiny impurities and debris, so that the coolant is more thoroughly purified. The filtered coolant can be recycled, and the different types of debris collected in the drawer 45 can be cleaned and processed regularly, achieving effective filtering of the coolant and classified collection of debris.

[0027] In summary, when using this device, first turn the handle 10, the handle 10 drives the lead screw 7 to rotate, and then drives the moving block 8 to move, thereby driving the slide bar 11 and the moving jacket 13 to slide along the chip collecting groove 38, and then adjust to a suitable position, then install the steel roller to be ground between the moving jacket 13 and the rotating jacket 16, and then start the grinding component 2 to grind the steel roller after adjusting it to a suitable position through the moving component 3; Then, the motor 15 is started, and the motor 15 drives the rotating jacket 16 and the steel roller inside it to rotate through the coupling. At the same time, the left driven wheel 17 drives the lower driven wheel 18 to rotate through the belt 19, and then drives the conveying rod 20 and the blade 21 to rotate, so as to start collecting and conveying the fallen debris; at the same time, the lower gear 31 is driven to rotate by the upper gear 30 outside the conveying rod 20, so as to drive the transmission shaft of the cooling pump 32 to rotate, so as to start the cooling pump 32 to absorb the coolant inside the cooling box 34, and then cool the grinding component 2 through the hose 35 and the nozzle 36, and At the same time, the right moving wheel 23 drives the small moving wheel 25 to rotate through the belt 24, so that the driven wheel 26 drives the interlocking wheel 28 to rotate through the belt 3 27, and then drives the two brush rods 29 to rotate, so as to collect the debris and coolant on the side wall of the chip collecting groove 38. At the same time, the conveyed debris and coolant fall into the filter box 40 through the conveying groove 22. After being filtered by the first filter screen 41, the second filter screen 42 and the filter cotton 43, the coolant flows back to the cooling box 34 through the recovery pipe 37. At the same time, the debris enters the drawer 45 through the debris channel 44 and waits for the next step of processing.
