Description

Technical Field

[0001] This invention relates to the field of cold rolling roll technology, specifically to a polishing and grinding device for a self-cleaning cold rolling work roll. Background Technology

[0002] As a core component of modern rolling industry, the surface precision and quality of cold rolling rolls directly determine the product grade of the final rolled strip. Therefore, regular restorative grinding of cold rolling rolls to remove fatigue layers, repair roll shape, and ensure roughness is a crucial maintenance step in steel rolling production.

[0003] Currently, the grinding of cold rolling rolls in the industry generally relies on CNC roll grinding machines or special polishing equipment. The core process of such equipment is to clamp the roll between the head and tailstock and drive it to rotate, while the CNC system controls the grinding head (grinding wheel or grinding stone device) to move precisely along the radial direction (to adjust the grinding depth) and axial direction (to cover the length of the roll body).

[0004] However, when the specifications (especially the diameter) of the roll to be ground change, the existing technical solutions have a series of significant defects, which seriously restrict production efficiency, processing quality and operational safety. The existing technical operation process is usually as follows: after the grinding of one roll is completed, if the diameter of the next roll is different, the operator must first stop the machine and readjust the distance of the grinding head to make it easy for the grinding head to adapt to cold rolling rolls of different diameters. This leads to a decrease in the grinding efficiency of cold rolling rolls and an increase in the time cost of grinding. Summary of the Invention

[0005] The purpose of this invention is to provide a polishing and grinding device for a self-cleaning cold rolling work roll, so as to solve the problem mentioned in the background art that the prior art requires frequent machine stops to adjust the grinding head for cold rolling rolls of different diameters and sizes, which leads to increased grinding time and decreased grinding efficiency.

[0016] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. During the cold rolling mill grinding process, the pushing mechanism drives the cold rolling mill to rotate and move to the left. When the mill reaches the opening of the polishing shell, it contacts and continuously abuts against the sensing rod, causing the sensing plate to move to the left inside the sensing shell. The liquid inside the shell is squeezed into the corresponding piston shell through two guide tubes. The liquid pressure pushes the piston plate to slide, thereby driving the piston rod, pushing plate, pushing rod, mounting arm, and polishing mill to move synchronously. At the same time, the pushing plate drives multiple driving rods and other pushing plates through multiple connecting grooves to achieve coordinated displacement of all polishing mills. As the sensing rod continues to be pressed, the sensing plate continues to move to the left until the polishing mill is completely in contact with the circumferential surface of the cold rolling mill. Through the above design, when grinding cold rolling mills of different sizes, the polishing mill can be in contact with the circumferential surface of the cold rolling mill for complete and thorough grinding, improving the grinding quality. Moreover, this device does not require stopping the machine to adjust the polishing mill; it can be automatically adjusted simply by the contact of the cold rolling mill, greatly improving the grinding efficiency and speed of the cold rolling mill.

[0017] Second, the cooling pipe can be connected to an external water source, and water can be sprayed out through the water inlet shell and spray holes to cool the cold rolling rolls during processing. At the same time, the liquid can be used to collect the waste generated during grinding and discharge it through the drain pipe to prevent the accumulation of waste and facilitate the centralized treatment of waste.

The working frame 2 is fixedly connected to the upper end of the bearing plate 1. The movable groove 206 is opened at one end of the working frame 2. The threaded block 207 is slidably connected in the movable groove 206. The electric cylinder 201 is fixedly connected to one end of the working frame 2, and the piston end of the electric cylinder 201 moves through one end of the working frame 2 and extends outward. The sliding block 202 and the mounting block 204 are respectively fixedly connected to the piston end of the electric cylinder 201 and one end of the screw 205. The screw 205 is threadedly connected in the threaded block 207. The connecting block 208 is integrally formed on one end of the screw 205. The plug-in groove 209 is opened at one end of the connecting block 208. It also includes a pressure relief mechanism, which consists of a pressure relief shell 5, a transmission pipe 504, a pressure valve 505, a pressure relief plate 501, a pressure relief rod 502, a reset plate 503, and a reset spring. The pressure relief shell 5 is fixedly connected to one end of the assembly plate 4. The transmission pipe 504 is fixedly connected to the circumferential surface of the sensing shell 401 and the pressure relief shell 5. The pressure relief plate 501 is slidably connected inside the pressure relief shell 5. The pressure relief rod 502 is fixedly connected to one end of the pressure relief plate 501, and one end of the pressure relief rod 502 moves through one end of the pressure relief shell 5 and extends outward. The reset plate 503 is fixedly connected to one end of the pressure relief rod 502. The reset spring is sleeved on the circumferential surface of the pressure relief rod 502. The pressure valve 505 is located inside the transmission pipe 504.

[0024] In a specific embodiment of the present invention, when it is necessary to grind the cold rolling roll, the flat end of the cold rolling roll drive end is first inserted into the insertion groove 209 and fixed. Then, the electric cylinder 201 fixedly connected to one end of the work frame 2 is started. The leftward movement of the piston end of the electric cylinder 201 synchronously pulls the sliding block 202, the first telescopic rod 203, the mounting block 204 and the screw 205 to move to the left. Since the screw 205 is threadedly connected to the threaded block 207, it will start to rotate when the screw 205 moves to the left and passes the threaded block 207, causing the screw 205 to rotate to the left, thereby synchronously driving the cold rolling roll to rotate to the left. When the cold rolling roll reaches the opening at one end of the polishing shell 101, the cold rolling roll and the sensing rod 409 come into contact. The continuous contact of the cold rolling roll with the sensing rod 409 causes the sensing plate 414 to move to the left within the sensing shell 401, squeezing the liquid outwards. This liquid is then transmitted through two guide pipes 402 to two piston shells 403, causing the piston plate 406 to slide within the piston shell 403. The movement of the piston plate 406 synchronously drives the piston rod 407, the push plate 408, the push rod 411, and the... The mounting arm 412 and the polishing roller 413 move synchronously, and the movement of the push plate 408 can also drive multiple driving rods 405 and two other push plates 408 to move synchronously through multiple connecting grooves, thereby completing the synchronous movement of multiple mounting arms 412 and polishing roller 413. When the sensing rod 409 is continuously pressed, it will drive the sensing plate 414 to move continuously to the left until the polishing roller 413 completes to adhere to the circumferential surface of the cold rolling roll. The high-speed rotation of the polishing roller 413 can then be used to grind and polish the circumferential surface of the cold rolling roll. When the sensing plate 414 moves to the left, the liquid in the sensing shell 401 is transferred to the piston shell 403 through the guide pipe 402, squeezing the piston plate 406. At this time, the liquid in the sensing shell 401 is diverted through the guide pipe 402, so the pressure on the transmission pipe 504 will be smaller. Therefore, the pressure valve 505 closes the transmission pipe 504, preventing the liquid from diverting into the transmission pipe 504. However, the continuous movement of the polishing roller 413 will inevitably come into contact with the circumferential surface of the cold rolling roller. At this time, the piston plate 406 cannot... The liquid inside the sensing shell 401 is continuously squeezed, causing its internal pressure to increase. This pressure will eventually act on the transmission pipe 504. The increased pressure will exceed the preset pressure of the pressure valve 505, causing the pressure valve 505 to open. Then the liquid can be transmitted through the transmission pipe 504 to the pressure relief shell 5 for diversion. The transmitted liquid can also squeeze the pressure relief rod 502 and drive the reset plate 503 to move, pulling the spring sleeved on the circumferential surface of the pressure relief rod 502 to accumulate force. After the cold rolling roll has completely passed through the polishing shell 101, it indicates that the cold rolling roll has been polished. At this point, the reverse drive cylinder 201 pushes its piston to the right, driving the screw 205 and the cold rolling roll to move to the initial position. The cold rolling roll can then be removed and replaced with a different one. As the cold rolling roll moves to the right, the pressure applied by the induction plate 414 to the induction shell 401 gradually decreases. Then, through the return force of the reset spring, the reset plate 503 is pulled back to the left, which in turn drives the pressure relief rod 502 and the pressure relief plate 501 to move to the left, squeezing the liquid in the pressure relief shell 5 back into the induction shell 401. Within 1, the squeezed and returned liquid will squeeze the induction plate 414 to move to the right and reset. At the same time as the induction plate 414 resets, the liquid in the piston shell 403 is drawn back into the induction shell 401 through the liquid column, which is convenient for subsequent use. Through the above design, when cold rolling rolls of different sizes are being polished, the polishing roller 413 can fit against the circumferential surface of the cold rolling roll for complete and thorough polishing, improving the polishing quality. Moreover, this device does not require stopping the machine to adjust the polishing roller 413. It can be automatically adjusted simply by the cold rolling roll against it, which greatly improves the polishing efficiency and speed of the cold rolling roll.

[0025] Preferably, multiple polishing rollers 413 are provided, and multiple polishing rollers 413 are simultaneously close to the cold rolling roll. This design can effectively prevent the thinner cold rolling roll from missing the polishing roller 413 due to excessive contact distance. The multiple sets of polishing rollers 413 can completely polish the circumferential surface of the cold rolling roll, preventing any omissions. Preferably, rubber rings are provided at piston mating devices such as piston housing 403 and piston rod 407 to prevent liquid leakage from the mating point. Preferably, the push rod 411 can give the mounting arm 412 a certain degree of mobility. When the cold rolling roll contacts the mounting arm 412, the mounting arm 412 can be squeezed to a small extent by the inclined surface at one end of the mounting arm 412, which facilitates the subsequent bonding of the polishing roller 413 to the circumferential surface of the cold rolling roll.

[0026] Preferably, two folding sealing plates 410 are fixedly connected between the two drive rods 405 and the two connecting grooves. The folding sealing plates 410 can prevent external dirt from entering the drive housing 404, and folding sealing plates 410 are provided between other connecting grooves and drive rods 405.

[0027] Preferably, the rotational movement of the polishing roller 413 is powered by a miniature drive motor (not shown) fixed within the mounting arm 412, ensuring that the polishing roller 413 can rotate at high speed to perform the polishing operation after moving to the mating position.

[0028] Preferably, the preset opening pressure of the pressure valve 505 is set according to the maximum working pressure of the system. This pressure corresponds to the maximum allowable contact stress required between the polishing roller 413 and the surface of the cold rolling roller. It should be noted that the preset pressure of the pressure valve 505 can be adjusted by those skilled in the art in practice.

[0029] Please refer to the details. Figure 1-10 One end of the connecting block 208 is provided with an insertion groove 209, and the screw 205 is provided with an extrusion groove 304. An extrusion plate 305 is slidably connected in the extrusion groove 304. One end of the extrusion plate 305 is fixedly connected with a moving rod 303. One end of the moving rod 303 movably passes through one side of the inner wall of the insertion groove 209, and one end of the moving rod 303 is fixedly connected with a trigger block 301. A first spring 302 is sleeved on the circumferential surface of the moving rod 303. Two sets of clamping mechanisms are provided in the insertion groove 209. The clamping mechanisms are hydraulically connected to the extrusion plate 305 and are used to extrude and fix the flat end of the cold rolling roll. Each clamping mechanism consists of a diversion groove 306, an abutment groove 307, an abutment plate 308, a trigger rod 309, and multiple sets of clamping components. The diversion groove 306 is opened on one side of the inner wall of the extrusion groove 304, the abutment groove 307 is opened on one side of the inner wall of the diversion groove 306, the abutment plate 308 is slidably connected in the abutment groove 307, the trigger rod 309 is fixedly connected to one end of the abutment plate 308, and one end of the trigger rod 309 moves through one side of the inner wall of the abutment groove 307 and extends outward. Multiple sets of clamping components are all located at one end of the insertion groove 209, and multiple sets of clamping components are in abutment contact with the trigger rod 309 for extruding and fixing the flat end of the cold rolling roll. Each clamping assembly consists of a clamping groove 311, a clamping rod 312, a moving block 310, and an extension spring. The clamping groove 311 is formed on the upper inner wall of the insertion groove 209. The clamping rod 312 is slidably connected in the clamping groove 311. The moving block 310 is fixedly connected to the circumferential surface of the clamping rod 312. The extension spring is fixedly connected between the moving block 310 and the connecting block 208.

[0030] In this embodiment: when the flat end of the cold rolling roll is inserted into the insertion groove 209 at the drive end, the gradually inserted flat end will press the trigger block 301, causing the trigger block 301, the moving rod 303, and the extrusion plate 305 to move to the right, and extruding the liquid in the extrusion groove 304 through the two diversion grooves 306 to the two abutment grooves 307, pushing the two abutment plates 308 and the trigger rod 309 outward. After the trigger rod 309 is pushed, it will contact the multiple clamping rods 312 in sequence, causing the multiple clamping rods 312 to move into the insertion groove 209. The movement of the multiple clamping rods 312 will press and fix the inserted flat end, preventing the flat end from falling out of the insertion groove 209. When it is necessary to detach the cold rolling roll, the screw 205 can be moved to the right and retracted into the threaded block 207. At this time, the cold rolling roll will abut against the work stand 2, causing the flat end to disengage from the insertion groove 209. Then, through the elastic expansion of the first spring 302, the trigger block 301 is pushed to the left, causing the extrusion plate 305 to move in the extrusion groove 304, drawing the liquid out of the abutment groove 307, and then pulling the abutment plate 308 and the trigger rod 309 back to the initial position. After the abutment of the trigger rod 309 is lost, the restoring force of the extended spring will retract the moving block 310 and the clamping rod 312 back to the initial position for convenient subsequent use.

[0031] Please refer to the details. Figure 1-10 The upper end of the polishing shell 101 is fixedly connected to a cooling pipe 6, and the lower end of the cooling pipe 6 is fixedly connected to a water injection shell 601. The lower end of the water injection shell 601 is provided with multiple water spraying holes 602. Multiple drain pipes 603 are fixedly connected to the circumferential surface of the support plate 1, and the lower ends of the multiple drain pipes 603 all penetrate the lower end of the support plate 1 and extend downward.

[0032] In this embodiment: the cooling pipe 6 can be connected to an external water source, and water is sprayed out through the water injection shell 601 and the water spraying hole 602 to cool the cold rolling roll during processing. At the same time, the liquid collects the waste generated during grinding and discharges it through the drain pipe 603 to prevent the accumulation of waste and facilitate the centralized treatment of waste.

[0033] Please refer to the details. Figure 1-10 The upper end of the connecting block 208 is fixedly connected to the second telescopic rod 3, the upper end of the second telescopic rod 3 is fixedly connected to the moving block 310, and the expansion spring is sleeved on the circumferential surface of the second telescopic rod 3. The inner walls on both sides of the movable groove 206 are provided with mounting grooves. Two vertical rods 211 are fixedly connected between the upper and lower inner walls of the two mounting grooves. Vertical blocks 210 are slidably connected to the circumferential surfaces of the two vertical rods 211. The two vertical blocks 210 are fixedly connected to the two ends of the threaded block 207 respectively.

[0034] Preferably, the upper end of the bearing plate 1 is fixedly connected to a plurality of support feet 102, and the upper ends of the plurality of support feet 102 are fixedly connected to a stabilizing plate 103 in pairs.

[0035] In this embodiment: the second telescopic rod 3 can prevent damage caused by the bending deformation of the extension spring. When the cold rolling roll needs to be placed, the cold rolling roll can be temporarily placed by the stabilizing plate 103. Then, the two vertical rods 211 drive the two vertical blocks 210 to move, and drive the screw 205 and multiple components to move vertically, so that the insertion groove 209 can be aligned with the flat end of the cold rolling roll. Then, as the screw 205 moves to the left, the flat end can be inserted into the insertion groove 209, improving the automation of the cold rolling roll installation. The first telescopic rod 203 can maintain the connection between the mounting block 204 and the sliding block 202 when the screw 205 rises and falls as a whole.

[0036] Working principle: When the cold rolling roll needs to be ground, firstly, the flat end of the cold rolling roll drive end is inserted into the insertion groove 209 and fixed. Then, the electric cylinder 201 fixedly connected to one end of the work frame 2 is started. The leftward movement of the piston end of the electric cylinder 201 synchronously pulls the sliding block 202, the first telescopic rod 203, the mounting block 204 and the screw 205 to move to the left. Since the screw 205 is threadedly connected to the threaded block 207, it will start to rotate when the screw 205 moves to the left and passes the threaded block 207, causing the screw 205 to rotate to the left, thereby synchronously driving the cold rolling roll to rotate to the left. When the cold rolling roll reaches the opening at one end of the polishing shell 101, the cold rolling roll and the sensing rod 409 come into contact. The continuous contact of the cold rolling roll with the sensing rod 409 causes the sensing plate 414 to move to the left within the sensing shell 401, squeezing the liquid outwards. This liquid is then transmitted through two guide pipes 402 to two piston shells 403, causing the piston plate 406 to slide within the piston shell 403. The movement of the piston plate 406 synchronously drives the piston rod 407, the push plate 408, the push rod 411, and the... The mounting arm 412 and the polishing roller 413 move synchronously, and the movement of the push plate 408 can also drive multiple driving rods 405 and two other push plates 408 to move synchronously through multiple connecting grooves, thereby completing the synchronous movement of multiple mounting arms 412 and polishing roller 413. When the sensing rod 409 is continuously pressed, it will drive the sensing plate 414 to move continuously to the left until the polishing roller 413 completes to adhere to the circumferential surface of the cold rolling roll. The high-speed rotation of the polishing roller 413 can then be used to grind and polish the circumferential surface of the cold rolling roll. When the sensing plate 414 moves to the left, the liquid in the sensing shell 401 is transferred to the piston shell 403 through the guide pipe 402, squeezing the piston plate 406. At this time, the liquid in the sensing shell 401 is diverted through the guide pipe 402, so the pressure on the transmission pipe 504 will be smaller. Therefore, the pressure valve 505 closes the transmission pipe 504, preventing the liquid from diverting into the transmission pipe 504. However, the continuous movement of the polishing roller 413 will inevitably come into contact with the circumferential surface of the cold rolling roller. At this time, the piston plate 406 cannot... The liquid inside the sensing shell 401 is continuously squeezed, causing its internal pressure to increase. This pressure will eventually act on the transmission pipe 504. The increased pressure will exceed the preset pressure of the pressure valve 505, causing the pressure valve 505 to open. Then the liquid can be transmitted through the transmission pipe 504 to the pressure relief shell 5 for diversion. The transmitted liquid can also squeeze the pressure relief rod 502 and drive the reset plate 503 to move, pulling the spring sleeved on the circumferential surface of the pressure relief rod 502 to accumulate force. After the cold rolling roll has completely passed through the polishing shell 101, it indicates that the cold rolling roll has been polished. At this point, the reverse drive cylinder 201 pushes its piston to the right, driving the screw 205 and the cold rolling roll to move to the initial position. The cold rolling roll can then be removed and replaced with a different one. As the cold rolling roll moves to the right, the pressure applied by the induction plate 414 to the induction shell 401 gradually decreases. Then, through the return force of the reset spring, the reset plate 503 is pulled back to the left, which in turn drives the pressure relief rod 502 and the pressure relief plate 501 to move to the left, squeezing the liquid in the pressure relief shell 5 back into the induction shell 401. Within 1, the squeezed and returned liquid will squeeze the induction plate 414 to move to the right and reset. At the same time as the induction plate 414 resets, the liquid in the piston shell 403 is drawn back into the induction shell 401 through the liquid column, which is convenient for subsequent use. Through the above design, when cold rolling rolls of different sizes are being polished, the polishing roller 413 can fit against the circumferential surface of the cold rolling roll for complete and thorough polishing, improving the polishing quality. Moreover, this device does not require stopping the machine to adjust the polishing roller 413. It can be automatically adjusted simply by the cold rolling roll against it, which greatly improves the polishing efficiency and speed of the cold rolling roll.
