Description

Technical Field

[0001] This utility model relates to the technical field of polishing equipment, and in particular to an online roller polishing device. Background Technology

[0002] In sheet and strip rolling mills, guide rollers are critical components used to guide and adjust the running direction of the sheet and strip, ensuring its stability during the rolling process. However, during operation, guide rollers are easily damaged due to prolonged friction and impact from the sheet and strip, as well as various factors in the working environment. Damage such as scratches, pits, and wear can occur on the roller surface. This not only affects the quality of the sheet and strip roller surface but may also lead to malfunctions and downtime during production, reducing production efficiency.

[0003] Currently, polishing techniques commonly used to repair damage to the surface of guide rollers have several shortcomings. First, most existing polishing methods require removing the guide roller from the metal strip rolling mill and then installing it in a specialized polishing device. This process not only increases labor intensity and time costs but may also cause further damage to the roller during disassembly and installation, reducing its service life. After polishing, the roller must be reinstalled into the rolling mill, making the entire process cumbersome and inefficient.

[0004] In addition, the existing polishing equipment has low compatibility with steering rollers, making it difficult to meet the polishing requirements of steering rollers of different sizes.

[0005] In summary, existing polishing devices have significant shortcomings in terms of polishing efficiency and adaptability. There is an urgent need for a new type of polishing device that can improve polishing efficiency and enhance adaptability in order to solve the above problems and ensure the normal operation of metal strip rolling equipment and the high-quality production of metal strip. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an online roller polishing device that can improve polishing efficiency and enhance adaptability.

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0008] An online roller polishing device includes a support base, a transverse drive module, a distance adjustment module, and a polishing module;

[0009] The lateral drive module is mounted on the support base and is rotatably connected to the support base;

[0010] The distance adjustment module is connected to the lateral drive module;

[0011] The polishing module is connected to the distance adjustment module, which adjusts the distance between the polishing module and the roller surface. The lateral drive module drives the lateral movement back and forth and rotates the lateral drive module to make it tangent to the roller surface.

[0012] In this technical solution, it is not necessary to remove the turntable rollers that need to be polished from the metal strip rolling equipment for polishing. The online roller surface polishing device can be set near the turntable rollers that need to be polished. Through the cooperation of the support base, the lateral drive module, the distance adjustment module and the polishing module, the turntable rollers can be polished. This not only improves the polishing efficiency, but also enhances the compatibility with turntable rollers of different sizes.

[0013] The working principle of the support base, lateral drive module, distance adjustment module, and polishing module is as follows:

[0014] The distance between the polishing module and the guide roller is adjusted by the distance adjustment module, allowing the polishing module to conform to the roller surface of guide rollers of different sizes. By rotating the lateral drive module, the angle between the distance adjustment module and the polishing module is adjusted so that the polishing module is tangent to the roller surface of the guide roller.

[0015] Furthermore, the lateral drive module includes a slide, a slide plate, a guide seat, and a lead screw transmission mechanism;

[0016] The slide block is rotatably connected to the support base;

[0017] Both the lead screw drive mechanism and the guide seat are installed inside the slide.

[0018] The guide seat is connected to the lead screw transmission mechanism;

[0019] The slide plate is connected to the guide seat and is placed between the guide seat and the slide block;

[0020] The distance adjustment module is connected to the guide seat.

[0021] In this technical solution, the guide seat, distance adjustment module, and polishing module are driven by a screw drive mechanism to reciprocate along the length of the guide roller, thereby polishing the roller surface of the guide roller through the polishing module.

[0022] Furthermore, the lead screw transmission mechanism includes a lead screw, a bearing, a motor, and a slider that cooperates with the lead screw;

[0023] The lead screw has two threaded grooves with the same pitch but opposite directions, and the lead screw is mounted in the slide block through a bearing;

[0024] The motor is connected to the lead screw, which drives the lead screw to rotate.

[0025] The slider is nested inside the guide seat.

[0026] In this technical solution, the lead screw only needs to rotate in one direction to drive the slider to reciprocate (reciprocating lead screw transmission principle).

[0027] Furthermore, a connector is provided between the lateral drive module and the support base;

[0028] The lateral drive module is connected to the connector;

[0029] The connector is rotatably connected to the support base, and the connector is provided with an array of circular holes distributed in an arc.

[0030] The support base has openings, and the angle of rotation of the lateral drive module can be adjusted by the combination of the openings, the array of circular holes, and the pin shaft.

[0031] Furthermore, the distance adjustment module is a cylinder;

[0032] The polishing module is connected to the piston rod of the cylinder.

[0033] Furthermore, the polishing module includes an oilstone mounting base and an oilstone;

[0034] The oilstone mounting base is connected to the piston rod of the cylinder;

[0035] The oilstone is installed on the oilstone mounting base, and polishes the roller surface of the steering roller by contacting the oilstone with the roller surface.

[0036] Furthermore, the cylinder is a three-axis cylinder.

[0037] Furthermore, the support base includes a fixed base, a movable base, and a hydraulic cylinder;

[0038] The mounting base is provided with a slot;

[0039] The movable seat is inserted into the slot of the fixed seat and partially extends out of the fixed seat;

[0040] The bottom end of the hydraulic cylinder is connected to the outside of the fixed seat, and the piston rod of the hydraulic cylinder is connected to the outside of the movable seat.

[0041] The opening is located on the movable base.

[0042] In this technical solution, the depth of the moving seat inserted into the slot of the fixed seat is controlled by a hydraulic cylinder, enabling the support seat to have a telescopic function. The height of the polishing module can be adjusted by the support seat, thereby adapting to the guide rollers located at different heights.

[0043] Furthermore, the fixed seat is shaped like a "⊥", which can greatly improve the stability of the support seat and prevent the online roller polishing device from tipping over.

[0044] Furthermore, the bottom of the support base is provided with a pulley with a locking function (the pulley is existing).

[0045] In this technical solution, when the online roller polishing device needs to be placed near the guide roller that needs to be polished, the pulley is adjusted to the rolling (unlocked) mode, which allows the online roller polishing device to easily approach the guide roller that needs to be polished. When the online roller polishing device is already placed near the guide roller that needs to be polished, and the guide roller needs to be polished, the pulley is adjusted to the locking mode.

[0046] Compared with existing technologies, the principles and advantages of this technical solution are as follows:

[0047] 1. There is no need to remove the guide rollers that need polishing from the metal strip rolling equipment for polishing. Simply set the online roller surface polishing device near the guide rollers that need polishing. With the cooperation of the support base, lateral drive module, distance adjustment module and polishing module, the guide rollers can be polished. This not only improves polishing efficiency, but also enhances the compatibility with guide rollers of different sizes.

[0048] The working principle of the support base, lateral drive module, distance adjustment module, and polishing module is as follows:

[0049] The distance between the polishing module and the guide roller is adjusted by the distance adjustment module, allowing the polishing module to conform to the roller surface of guide rollers of different sizes. By rotating the lateral drive module, the angle between the distance adjustment module and the polishing module is adjusted so that the polishing module is tangent to the roller surface of the guide roller.

[0050] 2. The depth of the moving seat inserted into the slot of the fixed seat is controlled by a hydraulic cylinder, giving the support seat a telescopic function. The height of the polishing module can be adjusted via the support seat, thus adapting to the guide rollers located at different heights. Attached Figure Description

[0058] The present invention will be further described below with reference to three specific embodiments:

[0059] Example 1.

[0063] Specifically, in this embodiment, the distance adjustment module 3 is a three-axis cylinder, which is connected to the guide seat 7.

[0064] Specifically, in this embodiment, the polishing module 4 includes an oilstone mounting base 12 and an oilstone 13. The oilstone mounting base 12 is connected to the piston rod of the three-axis cylinder; the oilstone 13 is mounted on the oilstone mounting base 12.

[0065] Specifically, in this embodiment, the slide 5 is fixedly connected to the connector 9, while the connector 9 is rotatably connected to the support base 1, and the connector 9 is provided with an array of circular holes 10 distributed in an arc; the support base 1 is provided with an opening, and the angle of rotation of the transverse drive module 2 is adjusted by the cooperation of the opening, the array of circular holes 10 and the pin 11 (the pin 11 passes through the opening and then through the circular holes of different angles in the array of circular holes 10).

[0066] In this embodiment, it is not necessary to remove the steering roller that needs to be polished from the metal strip rolling equipment for polishing. The online roller surface polishing device can be set near the steering roller that needs to be polished.
