Description

Technical Field

[0001] This utility model relates to the field of rolling mill processing technology, specifically to a rolling mill grinding device. Background Technology

[0002] Rolls are the main working parts and tools on rolling mills that cause continuous plastic deformation of metal. Steel is typically rolled using the pressure generated by the rolling of a pair or a set of rolls. Rolls primarily bear the dynamic and static loads during rolling, as well as the effects of wear and temperature changes. A roll mainly consists of three parts: the roll body, the roll neck, and the shaft end. During roll manufacturing, grinding equipment is used to finish the produced rolls. However, with traditional grinding equipment, it has been found that the installation height of the grinding cutter and the placement height of the roll are fixed, ultimately making it impossible to adjust the grinding depth. This results in uneven grinding depths on the roll surface, reducing the yield rate of produced rolls. Existing cold rolling rolls generate a significant amount of metal dust and fine debris during grinding, which can easily cause air pollution when dispersed into the air. Simultaneously, the grinding equipment generates considerable heat during operation, and prolonged exposure to high temperatures reduces its service life.

[0003] Therefore, it is necessary to provide a roll precision grinding device. Utility Model Content

[0026] according to Figure 1-4 This embodiment provides a roll fine grinding device, including a worktable 1. A grinding frame 2, a mounting bracket 3, and a mounting bracket 4 are mounted on the worktable 1. The grinding frame 2 is fixedly connected to the worktable 1. A grinding assembly 20 is mounted on the grinding frame 2. The grinding assembly 20 includes a motor 21, a threaded rod 22, and a grinding table 23. The motor 21 is fixedly mounted on the grinding frame 2, and its output end is fixedly connected to the threaded rod 22. The grinding table 23 is threadedly connected to the threaded rod 22, which is rotatably connected to the grinding frame 2. The grinding table 23 is slidably connected to the grinding frame 2. Lateral movement of the grinding table 23 is achieved through the motor 21 and the threaded rod 22, allowing the grinding table 23 to slide against the grinding frame 2, thus absorbing the weight of the grinding table 23. To prevent the threaded rod 22 from bending, a rack 231 is fixedly installed on the grinding table 23. A housing 24 is slidably installed on the grinding table 23. A motor 25 is fixedly installed inside the housing 24. A gear 26 is fixedly installed at the output end of the motor 25. The gear 26 meshes with the rack 231. The gear 26 and rack 231 are configured so that the housing 24 connected to the grinding table 23 can move along the direction of the rack 231. A hydraulic push rod 27 and a telescopic guide rod 28 are fixedly installed on the housing 24. An installation plate 29 is fixedly installed at the output end of the hydraulic push rod 27 and the telescopic guide rod 28. A dust suction head 5 and a grinding cutter 6 are fixedly installed on the installation plate 29. The dust suction head 5 is used to adsorb the floating metal particles generated by the grinding cutter 6 during grinding.

[0027] The mounting frame 3 and the mounting frame 4 are symmetrically arranged. A hydraulic push rod 31 is fixedly installed on both the mounting frame 3 and the mounting frame 4. A mounting platform 32 is fixedly installed at the output end of the hydraulic push rod 31. A rotary chuck 33 is fixedly installed on the mounting platform 32. The mounting frame 3 is fixedly connected to the worktable 1, and the mounting frame 4 is slidably connected to the worktable 1. Moving the mounting frame 4 allows for grinding of rolls of different lengths.

[0028] A rack 11 is fixedly installed on one side of the workbench 1. The rack 11 is arranged along the length direction. A housing 41 is fixedly installed on the mounting frame 4. A motor 42 is fixedly installed inside the housing 41. A gear 43 is fixedly installed at the output end of the motor 42. The gear 43 meshes with the rack 11, which facilitates the movement of the mounting frame 4. The housing 41 is installed so that the motor 42 can mesh with the rack 41 when the gear 43 is installed.

[0029] A blower 7 is also fixedly installed on the workbench 1. The blower 7 is connected to the dust suction head 5 through a corrugated pipe 8, so that the blower 7 and the dust suction head 5 are not easily disconnected when the dust suction head 5 is moved.

[0030] A filter box 9 is provided between the exhaust fan 7 and the corrugated pipe 8. The upper end face of the filter box 9 is fixedly connected to the corrugated pipe 8, and the lower end face of the filter box 9 is fixedly connected to the input end of the exhaust fan 7.

[0031] The filter box 9 is equipped with a filter screen 91, which is sealed and slidably connected to the filter box 9. After the filter screen 91 is covered with metal shavings, it is easy to replace.

[0032] A handle 92 is fixedly installed on the filter screen 91 to facilitate the removal of the filter screen.

[0033] An electromagnetic brake 251 is also fixedly installed inside the housing 24. The electromagnetic brake 251 is fixedly connected to the drive shaft of the motor 25. The electromagnetic brake is a conventional locking component in the mechanical field. It controls the engagement and disengagement of the brake pads and the drive shaft through an electrical signal, which can effectively solve the problem of motor self-rotation caused by vibration. When the housing 24 moves to the preset position, the electromagnetic brake 251 is activated and locks the drive shaft of the motor 25, preventing relative displacement between the gear 26 and the rack 231, and ensuring the positional accuracy of the grinding tool 6.

[0034] An electromagnetic brake 421 is also fixedly installed inside the housing 41. The electromagnetic brake 421 is fixedly connected to the drive shaft of the motor 42. The electromagnetic brake is a conventional locking component in the mechanical field. It controls the engagement and disengagement of the brake pads and the drive shaft through an electrical signal, which can effectively solve the problem of the motor rotating on its own due to vibration. When the mounting bracket 4 moves to the preset position, the electromagnetic brake 421 is activated and locks the drive shaft of the motor 42, preventing the gear 43 from sliding along the rack 11 and ensuring the clamping stability of the roll.

[0035] The specific operation is as follows: When grinding the roll, start motor 3 43, adjust mounting bracket 1 3 and mounting bracket 2 4 to the appropriate position, and use the rotating chuck 33 installed on mounting bracket 1 3 and mounting bracket 2 4 to clamp and rotate the roll. Drive motor 1 21 to adjust the grinding table 23 to the appropriate position, drive hydraulic push rod 1 27 to push the dust suction head 5 and grinding cutter 6, push the grinding cutter 6 to the grinding position, drive the exhaust fan 7, and simultaneously drive motor 1 21 to grind the roll with the grinding cutter 6. During the grinding process, the dust suction head 6 sucks in the air around the grinding cutter 6 to generate metal shavings. At the same time, the airflow generated by the dust suction head 5 during exhaust helps to cool the grinding cutter 6, which generates heat during grinding. When one roll is finished grinding, remove the filter screen 91 from the filter box 9 to clean the metal deposits on the filter screen, so that the pressure of the dust suction head 5 adsorbing the air around the grinding cutter 6 remains unchanged when grinding the roll next time.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
