Description

Technical Field

[0001] This invention relates to the field of grinding equipment technology, specifically to an automatic grinding equipment, system and method for rolling mill grooves. Background Technology

[0002] In the production of bar and wire rod, multiple rolling processes are required to obtain steel wire of the target specifications. The heated billet enters the roughing mill for rolling, followed by head cutting by a flying shear. After head cutting, it enters the intermediate mill for further rolling. A slitting rolling process is set after the intermediate mill to cut the bar into multiple smaller bars. The slitting bars then enter the finishing mill for precision rolling to ensure the dimensional accuracy of the final product. After high-frequency operation, the rolls inside the mill require surface grinding to remove oil, iron oxide, and other foreign matter from the rolling grooves, and to grind textures on the surface to increase friction and prevent slippage of the steel wire during production, which could cause steel pile-up and shutdown.

[0003] Currently, the factory uses manual grinding, where workers manually grind rolls inside the mill using handheld angle grinders and a device that allows the rolls to rotate. Some rolls are obstructed by mechanical obstructions, limiting the angle and making manual grinding inconvenient. Many rolls require grinding during maintenance, and grinding all the roll grooves takes a long time, consuming a great deal of physical strength. For large-sized rolls in the roughing mill, the time and effort required are 3-5 times that of finishing mill rolls. During grinding, continuous force is needed to keep the grinding wheel in close contact with the groove surface. Manual control is affected by factors such as operating experience and physical strength, resulting in uneven force control. Furthermore, existing grinding equipment struggles to adaptively adjust the grinding force, easily leading to either insufficient or excessive grinding of some grooves, affecting the processing quality of subsequent products. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automatic grinding equipment, system, and method for rolling mill grooves, which solves the problems of limited grinding angles, inconvenience of manual grinding, and uneven grinding force, which lead to uneven grinding of the grooves and affect product processing quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: In a first aspect, the present invention provides an automatic grinding equipment for roll grooves, including a platform cart and a grinding device.

[0006] Furthermore, the damping mechanism includes a grinding arm rotatably connected to a support plate via a rotating shaft. The grinding arm has a damping groove inside, and a first guide rod is fixedly connected to the inner wall of the damping groove. A limiting rod penetrating into the damping groove is provided at one end of the grinding arm from the support plate, and a limiting block is fixedly connected to one end of the limiting rod inside the damping groove. A second guide rod is fixedly connected to the side of the limiting block opposite to the first guide rod. A damping spring sleeved on the surface of the first and second guide rods is fixedly connected between the inner wall of the damping groove and one side of the limiting block. The grinding device is fixed at the end of the limiting rod located outside the grinding arm.

[0007] Furthermore, the angle adjustment mechanism includes a fixed plate fixed to the top of the support plate by a support rod. A servo motor is fixedly connected to the top of the fixed plate. A rotating shaft that passes through the fixed plate and is rotatably connected to the top of the support plate is fixedly connected to the output end of the servo motor. A gear is fixedly connected to the surface of the rotating shaft. A sector-shaped internal gear plate that meshes with the gear teeth is provided between the fixed plate and the support plate. A connecting rod is rotatably connected to the top of the sector-shaped internal gear plate, and the other end of the connecting rod is rotatably connected to the grinding arm through a connector.

[0008] Furthermore, the angle adjustment mechanism includes a fixed plate fixed to the top of the support plate by a support rod, and a sector toothed plate fixed to the end of the grinding arm away from the grinding device. A servo motor is fixedly connected to the top of the fixed plate, and a rotating shaft that passes through the fixed plate and is rotatably connected to the top of the support plate is fixedly connected to the output end of the servo motor. A gear that meshes with the sector toothed plate is fixedly connected to the surface of the rotating shaft.

[0009] Furthermore, the top of the control box is equipped with a control panel and a touch screen.

[0010] Furthermore, the position coarse adjustment structure includes an X-axis adjustment track for adjusting the X-axis position of the grinding device, a Y-axis adjustment track for adjusting the Y-axis position of the grinding device, and a Z-axis adjustment track for adjusting the Z-axis position of the grinding device. The grinding fine adjustment mechanism is located on top of the Y-axis adjustment track. The position coarse adjustment structure also includes a pitch adjustment component for adjusting the pitch angle of the Z-axis adjustment track.

[0011] Furthermore, both the position coarse adjustment mechanism and the control box are fixed on the top of the platform vehicle, or the control box is fixed on the top of the platform vehicle and the position coarse adjustment mechanism is fixed on the top of the control box.

[0012] Secondly, the present invention provides an automatic grinding system for roll grooves, including an information processing and control system, an image recognition system, a position adjustment system and an automatic grinding system integrated in a control box.

[0013] Thirdly, the present invention provides an automatic grinding method for the grooves of rolling mill rolls, specifically including the following steps: Move the equipment to the work location; Select the roll with the corresponding number, the visual recognition camera captures the roll image, the image recognition system analyzes and recognizes the image, the position adjustment system controls the operation of the position coarse adjustment mechanism, adjusts the position and pitch angle of the grinding device, the image recognition system automatically numbers the groove, and the groove to be ground is selected through the touch screen. After receiving the task target, the information processing and control system activates the laser rangefinder to finely adjust the position of the grinding device so that it is directly facing the target groove and reaches the preset distance. The system prompts the worker that the equipment is ready and starts the grinding operation through the control panel. During the grinding process, the distance between the grinding device and the groove is controlled according to the data measured by the laser rangefinder. After the grinding device works for the specified grinding time, the grinding device is controlled to move backward a specified distance. Then, the vision recognition camera takes multiple pictures and the image recognition system identifies the surface texture of the groove to determine whether the grinding is complete. If grinding is completed, a prompt will be issued. After the worker confirms, the "Complete Work" button on the control panel will be triggered to release the wheel lock-up. The worker will then proceed to the next work position. If the grinding work is not completed, a supplementary grinding interface will pop up on the touch screen, where the worker can manually select the supplementary grinding time to perform a second operation until the grinding work is completed.

[0014] Furthermore, the fine-tuning of the position and orientation of the polishing device specifically includes: A visual recognition camera captures images of the roll groove, and an image recognition system identifies the images. The laser point emitted by the laser rangefinder determines the relative position of the grinding device and the target roll groove. The position adjustment system controls the coarse adjustment mechanism and the fine adjustment mechanism to adjust the grinding position of the grinding device. At the same time, the distance between the grinding device and the roll groove is adjusted based on the data measured by the laser rangefinder.

[0015] Compared with the prior art, the present invention has the following advantages: (1) The automatic grinding equipment, system and method for the roll groove does not require manual hand-held grinding, effectively reducing grinding operation time and reducing the labor intensity of workers. In addition, the equipment is equipped with a laser rangefinder combined with a position coarse adjustment mechanism and a grinding fine adjustment mechanism. The position adjustment system controls the operation of the position coarse adjustment mechanism and the grinding fine adjustment mechanism to adjust the grinding position of the grinding device. At the same time, the distance between the grinding device and the groove is adjusted by the data measured by the laser rangefinder, so that the force between the grinding wheel on the grinding device and the roll groove always changes within a small range, thereby making the grinding point force more uniform during the grinding process, and thus making the grinding effect more stable, preventing the groove surface from being unevenly ground, which is conducive to improving the processing quality of wire.

[0016] (2) The automatic grinding equipment, system and method for the roll groove can adjust the swing amplitude of the grinding device according to the actual use requirements by setting an angle adjustment mechanism, so that the equipment can be applied to the grinding of grooves of different widths and has stronger applicability.

[0017] (3) The automatic grinding equipment, system and method for the roll grooves of the rolls are as follows: by selecting the roll with the corresponding number, the visual recognition camera takes the roll image, the image recognition system analyzes and recognizes the image, the position adjustment system controls the operation of the position coarse adjustment mechanism, and the information processing control system starts the laser rangefinder after receiving the task target to perform fine adjustment of the grinding device position and pitch angle.

Moreover, the coordinate position of the grinding device in the up, down, left and right directions and the pitch angle can be freely adjusted, so that the equipment can be used in different working scenarios.

[0018] (4) The automatic grinding equipment, system and method for the rolling mill groove identifies the surface texture of the groove through the image recognition system, determines whether the grinding is completed, and automatically identifies and judges the grinding effect, so that the grinding results are standardized and uniform, which is beneficial to the processing of subsequent products.

[0030] Please see Figure 8 The present invention provides a technical solution: an automatic grinding system for rolling mill grooves, including an information processing control system 11, an image recognition system 12, a position adjustment system 13 and an automatic grinding system 14 integrated in a control box 4. The information processing control system 11 decides the next step of the operation based on the information processing results and issues control signals. Example

[0031] This invention provides a technical solution: an automatic grinding method for the grooves of rolling mill rolls, specifically including the following steps: Move the equipment to the work position; the work position is set in advance, a fixed area is marked on site, and the platform vehicle 1 is manually pushed to the designated area with the help of electric drive, triggering the "stop" button on the control panel 9 to lock the wheels and put the platform vehicle 1 into the locked state. The rolls in the factory are numbered. Rolls with the same number correspond to the same groove width and depth, that is, the swing amplitude and tilt angle of the grinding device 2 are the same. Click the corresponding roll number on the touch screen 10, and the visual recognition camera 6 captures the roll image. The image recognition system 12 analyzes and recognizes the image. According to the recognition result, the position adjustment system 13 controls the position coarse adjustment mechanism 3 to work, and adjusts the position of the grinding device in the X, Y, and Z axis directions, so that the grinding device 2 moves in front of the roll with the corresponding number. The position adjustment system 13 controls the position coarse adjustment mechanism 3 to run, and adjusts the position and pitch angle of the grinding device 2. The image recognition system 12 automatically numbers the grooves. The groove to be ground is selected through the touch screen 10. After receiving the task target, the information processing and control system 11 activates the laser rangefinder 7. Based on the relative position of the laser point emitted by the laser rangefinder 7 and the target groove, as well as the measured distance from the grinding device 2 to the roller, the position and posture of the grinding device 2 are finely adjusted so that it faces the target groove and reaches the preset distance, so that the grinding wheel is in close contact with the groove. The control box 4 is equipped with voice prompts and indicator lights. The system prompts the worker that the equipment is ready and the grinding work is started through the control panel 9. The information processing control system 11 simultaneously starts the grinding device 2 and the roll self-rotation device. This system establishes a wireless communication connection with the on-site rolling mill PLC control system and can control the rotation of the roll. During the grinding process, the grinding device 2 is controlled to swing left and right through the angle adjustment mechanism 52 for grinding. The distance between the grinding device 2 and the groove is controlled according to the data measured by the laser rangefinder 7. Combined with the damping mechanism 53, the force between the grinding wheel and the roll is made uniform to ensure the grinding quality. After the grinding device 2 has worked for the specified grinding time, the grinding time is calculated according to the different roll sizes and speeds to complete one revolution of grinding. The grinding device 2 is then controlled to move backward a specified distance so that the grinding wheel is removed from the groove surface. Then, the visual recognition camera 6 takes multiple pictures and the image recognition system 12 identifies the texture of the groove surface to determine whether the grinding is complete. The grinding is complete when the groove surface has no smooth breaks and has a uniform Z-shaped pattern. If grinding is completed, a prompt will be issued. After the worker confirms, the "Complete Work" button on the control panel 9 will be triggered to release the wheel lock-up. Then, the worker will proceed to the next work position. If the grinding work is not completed, the touch screen 10 will pop up a supplementary grinding interface, where the worker can manually select the supplementary grinding time to perform a second operation until the grinding work is completed.

[0032] In this embodiment, the fine-tuning of the position and orientation of the polishing device 2 specifically includes: The visual recognition camera 6 captures images of the roll groove, the image recognition system 12 recognizes the images, and the laser point emitted by the laser rangefinder 7 determines the relative position of the grinding device 2 and the target roll groove. The position adjustment system 13 controls the position coarse adjustment mechanism 3 and the grinding fine adjustment mechanism 5 to adjust the grinding position of the grinding device 2. At the same time, the distance between the grinding device 2 and the roll groove is adjusted based on the data measured by the laser rangefinder 7.
