Description

Technical Field

[0001] This invention relates to the field of roller processing technology, and in particular to a roller polishing and grinding device based on a bidirectional Y-shaped structure. Background Technology

[0002] Rollers are key components in industries such as steel rolling and papermaking. Their surface quality determines the shape and surface smoothness of the strip steel, and may affect the uniformity and tension stability of the paper. Therefore, it is necessary to polish and grind the rolls to ensure product quality.

[0003] Currently, belt grinding is widely used for roller polishing and grinding. The typical equipment structure is as follows: the abrasive belt is tensioned between the driving wheel and the driven wheel, and the roller shaft presses the abrasive belt against the roller surface. Material removal is achieved through the relative motion between the high-speed rotating abrasive belt and the roller. During the grinding process, in order to control grinding heat and flush away chips, a fixed coolant nozzle is usually installed on the outside of the abrasive belt, that is, on the front side where the abrasive belt contacts the roller, to spray water-based or oil-based coolant into the grinding arc area.

[0004] However, the following problems exist in the current process of grinding rollers with abrasive belts: 1. Existing roller polishing and grinding equipment usually only sprays coolant from the side of the abrasive belt processing surface to the grinding arc area, and cannot cool and jet impact the back of the abrasive belt, resulting in the coolant being difficult to evenly cover the entire grinding arc area, the temperature distribution in the grinding area is uneven, and it is easy to cause local overheating, burning and thermal deformation.

[0005] 2. During the grinding process, metal chips easily adhere to and clog the gaps between the abrasive grains of the abrasive belt. It is difficult to loosen and remove the chips embedded in the abrasive belt by simply rinsing the machined surface. The abrasive belt changes from a grinding state to a friction state, and the grinding heat rises sharply, which further aggravates the thermal damage to the workpiece and shortens the life of the abrasive belt.

[0006] Therefore, the problems of uneven cooling in the grinding arc zone and difficulty in removing chips from the abrasive belt are technical problems that need to be solved by those skilled in the art. Summary of the Invention

[0007] In view of the above problems, the present invention provides a roller polishing and grinding device based on a bidirectional Y-shaped structure to solve the aforementioned technical problems.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a roller polishing and grinding device based on a bidirectional Y-shaped structure, comprising a movable seat and a fixed plate; the fixed plate is provided with a grinding mechanism.

[0009] As a preferred embodiment, the grinding mechanism includes two support plates located on the front side of the fixed plate. The two support plates are connected to the fixed plate by a column and then fixedly connected. Mounting plates are slidably mounted on both support plates. Two rollers are rotatably mounted between the mounting plates. An adjustment part is provided on the fixed plate. A roller is rotatably mounted on the adjustment part. A roller is rotatably mounted on the fixed plate. A sanding belt is wound on rollers one, two, and three. A driving part is provided on the moving seat, and a tensioning part is provided on the support plate.

[0010] As a preferred embodiment, a liquid injection hole is provided in the middle of the roller shaft, and liquid outlet holes communicating with the liquid injection hole are evenly provided on the roller shaft. A rotary joint communicating with the liquid injection hole is installed at the end of the roller shaft, and an arc-shaped baffle is installed on the mounting plate, with a nozzle installed on the arc-shaped baffle.

[0011] As a preferred embodiment, the fixed plate is provided with a slag removal part, which includes a shaft column rotatably mounted on the fixed plate, an adhesive rod detachably mounted on the shaft column, and a linkage part between the shaft column and the roller shaft.

[0012] As a preferred embodiment, during grinding, the linkage causes the sticking rod to rotate with the roller shaft. Coolant is ejected from the outlet through the rotary joint, impacting the back of the sanding belt to loosen the chips and cool the sanding belt. The nozzle sprays coolant onto the back of the sanding belt, and the sticking rod adheres to the loosened chips.

[0013] As a preferred embodiment, the tensioning part includes a base fixedly installed between the support plates, an electric push rod fixedly installed at the left end of the base, and a connecting plate fixedly installed at the right end of the support plates. The telescopic section of the electric push rod is fixedly connected to the right end of the connecting plate.

[0014] As a preferred embodiment, a circular hole is coaxially opened at the right end of the shaft column, and an adhesive rod is inserted into the circular hole. A disc is coaxially fixedly installed on the adhesive rod, and a limit post is uniformly fixedly installed at the left end of the disc along its circumference. A limit hole corresponding to the limit post is opened on the shaft column, and the limit post is magnetically attracted to the inner wall of the limit hole.

[0015] As a preferred embodiment, the adjusting part includes a connecting rod rotatably mounted on a fixed plate, a roller shaft rotatably mounted on the connecting rod, and a cylinder rotatably mounted on the fixed plate, the telescopic section of the cylinder being rotatably connected to the connecting rod.

[0016] As a preferred embodiment, a fixing frame is fixedly installed on the fixing plate above the adhesive stick, and a scraper is fixedly installed on the fixing frame. The scraper has evenly arranged comb teeth on its lower part, and the comb teeth are tangentially attached to the adhesive stick.

[0017] As a preferred embodiment, the linkage includes synchronous pulleys fixedly mounted on the shaft column and the roller shaft, and a transmission belt is connected between the two synchronous pulleys.

[0018] As a preferred embodiment, the drive unit includes a motor fixedly mounted on a movable base, and the output shaft of the motor is fixedly connected to the roller shaft.

[0019] As a preferred embodiment, anti-slip textures are provided on roller shaft one, roller shaft two, and roller shaft three.

[0020] As a preferred embodiment, the outer layer material of the adhesive rod is an adhesive polymer material.

[0021] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: First, the present invention, by simultaneously setting three functional structures on the back of the abrasive belt—jet cooling, spray cooling, and adhesion cleaning—allows the coolant to act uniformly on the grinding arc area from the back, while loosening and adhering and removing the chips in the gap between the abrasive grains of the abrasive belt. This solves the problem of uneven cooling in the arc area caused by cooling only from one side of the processing surface in the prior art, as well as the problem of reduced grinding capacity and thermal damage caused by chip blockage, and significantly improves the quality and efficiency of roller polishing and grinding.

[0022] Second, the present invention sprays coolant onto the back of the abrasive belt through the outlet hole on the contact wheel, and combines it with the nozzle on the arc baffle to spray coolant onto the back of the abrasive belt, so that the coolant evenly covers the entire grinding arc area from the back, avoiding local overheating, burning and thermal deformation caused by one-sided cooling.

[0023] Third, the present invention uses liquid ejected from the liquid outlet to impact the back of the abrasive belt, loosening the chips embedded in the gaps between the abrasive grains of the abrasive belt. Then, the loosened chips are adhered and carried away by the adhesive rod that rotates synchronously with the contact wheel, thereby clearing the blockage of the abrasive belt, restoring the abrasive belt to the grinding state, and avoiding a sharp increase in grinding heat and a shortened abrasive belt life.

[0024] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] like Figure 1 As shown, a roller polishing and grinding device based on a bidirectional Y-shaped structure includes a movable seat 10 and a fixed plate 11 fixed thereon; a grinding mechanism 2 is provided on the fixed plate 11.

[0037] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the grinding mechanism 2 includes two support plates 20 fixedly installed at the rear end of the fixed plate 11. A support column 21 is fixedly installed between the two support plates 20. A mounting plate 22 is slidably installed on the opposite surfaces of the two support plates 20. Two symmetrical rollers 23 are rotatably installed between the two mounting plates 22. An adjustment part 5 is provided on the fixed plate 11. A roller 24 is rotatably installed on the adjustment part 5. A roller 3 25 located below the roller 24 is rotatably installed on the fixed plate 11. A sanding belt 26 is connected to the rollers 23, 24, and 35. A drive part is provided on the moving seat 10. A tensioning part 4 is provided on the support plate 20.

[0038] like Figure 4 , Figure 5 and Figure 6 As shown, a liquid injection hole is coaxially opened in the middle of the roller shaft 23, and liquid outlet holes 230 communicating with the liquid injection hole are evenly opened on the circumferential surface of the roller shaft 23. A rotary joint 231 is provided at the end of the roller shaft 23, and the rotating section of the rotary joint 231 is connected to the liquid injection hole. An arc-shaped baffle 232 located on the right side of the roller shaft 23 is fixedly installed between the two mounting plates 22, and a nozzle 233 is installed on the arc-shaped baffle 232.

[0039] like Figure 3 and Figure 4 As shown, the tensioning part 4 includes a base 40 fixedly installed between the support plates 20. An electric push rod 41 is fixedly installed on the left end of the base 40, and a connecting plate 42 is fixedly installed on the right end of the support plates 20. The telescopic section of the electric push rod 41 is fixedly connected to the right end of the connecting plate 42.

[0040] like Figure 3 , Figure 4 and Figure 7 As shown, a slag removal part 3 is provided on the fixed plate 11. The slag removal part 3 includes a shaft column 30 rotatably mounted on the fixed plate 11. An adhesive rod 31 is detachably mounted on the shaft column 30. The adhesive rod 31 abuts against the processing surface of the sanding belt 26. A linkage part 6 is provided between the shaft column 30 and the roller shaft 25.

[0041] like Figure 1 and Figure 2 As shown, the adjustment part 5 includes a connecting rod 50 rotatably mounted on the fixed plate 11, a roller shaft 24 rotatably mounted on the connecting rod 50, and a cylinder 51 rotatably mounted on the fixed plate 11. The telescopic section of the cylinder 51 is rotatably connected to the connecting rod 50.

[0042] like Figure 1 and Figure 3 As shown, the drive unit includes a motor 27 fixedly mounted on the movable seat 10, and the output shaft of the motor 27 is fixedly connected to the roller shaft 25.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, anti-slip textures are provided on roller shaft 1 23, roller shaft 24 and roller shaft 3 25.

[0044] like Figure 7 As shown, the outer layer material of the adhesive rod 31 is an adhesive polymer material.

[0045] like Figures 1 to 7 As shown, during actual operation, the roller to be processed is fixed by an external rotating clamping device (such as a headstock and tailstock tip) and rotates around its own axis. The moving seat 10 is mounted on an external drive device (such as a cross slide or CNC moving mechanism) that can move it forward, backward, left and right. First, the external drive device drives the entire device to move to the side of the roller and continues to move forward, so that the sanding belt 26 gradually approaches and adheres to the surface of the rotating roller. At this time, the existing coolant nozzles used for rinsing the processed surface are retained and kept working, continuously spraying coolant into the grinding arc area to remove most of the grinding heat and chips.

[0046] During the bonding process, the telescopic section of the electric push rod 41 is fixedly connected to the connecting plate 42. The connecting plate 42 is fixed between the right ends of the two support plates 20. When the electric push rod 41 telescopically extends, it pushes the connecting plate 42. Thus, when the support plate 20 moves, the mounting plate 22 slidably mounted on it drives the two mounting plates 22 to move relative to the fixed plate 11. The two symmetrical roller shafts 23, which are rotated between the mounting plates 22, move together with the support plate 20. Through this action, the wrapping curvature of the sanding belt 26 on the roller body is adjusted to the optimal state, and the tension of the sanding belt 26 is maintained. When the diameter of the roller body changes, the electric push rod 41 can adjust the position of the support plate 20 in real time so that the sanding belt 26 always fits tightly against the rotating roller body with a suitable curvature.

[0047] When the motor 27 in the drive unit starts, the output shaft of the motor 27 directly drives the roller 3 25 to rotate. The roller 3 25 drives the roller 1 23 and roller 2 24 to rotate synchronously through the sanding belt 26. The cylinder 51 in the adjustment unit 5 extends and retracts to push the connecting rod 50 to swing, changing the position of the roller 2 24, and further assisting in adjusting the curvature of the sanding belt 26 wrapping the roller body. When the two symmetrical roller 1 23 move with the support plate 20, the arc-shaped baffle 232 installed between them and the nozzle 233 installed on it move with the roller 1 23, always aligned with the working area on the back of the sanding belt 26.

[0048] During the grinding process, in addition to external coolant flushing the machined surface, the present invention also supplies cooling and lubricating fluid to the back of the abrasive belt 26 through roller shaft 23. The cooling and lubricating fluid enters the injection hole inside roller shaft 23 through rotary joint 231, and then is ejected outward from the outlet hole 230 on the circumferential surface of roller shaft 23. Since roller shaft 23 is close to the back of abrasive belt 26, the ejected liquid directly impacts the back of abrasive belt 26. On the one hand, it penetrates into the abrasive layer of abrasive belt 26, pre-wetting and cooling abrasive belt 26 and reducing the temperature of the grinding zone. On the other hand, the jet impact force loosens the chips and impurities embedded in the gaps between abrasive grains of abrasive belt 26, making them easy to fall off. At the same time, nozzle 233 sprays coolant to the back of abrasive belt 26 through external liquid supply system to further supplement cooling and lubrication. Arc-shaped baffle 232 blocks splashed liquid and guides its flow direction to prevent it from scattering everywhere.

[0049] The sanding belt 26, carrying loosened impurities, continues to run through the area of ​​roller 23. After leaving roller 23, the sanding belt 26 enters the location of the slag removal section 3. The sticking rod 31 in the slag removal section 3 rotates synchronously with roller 25 under the action of the linkage 6. The outer layer material of the sticking rod 31 is an adhesive polymer material, which keeps in contact with the processing surface of the sanding belt 26 and adheres the loose chips and impurities on the surface of the sanding belt 26. The sticking rod 31 is detachable to achieve reliable positioning and quick replacement.

[0050] Throughout the process, the anti-slip textures on roller 1 23, roller 2 24, and roller 3 25 increase the friction with the back of the abrasive belt 26, preventing the abrasive belt 26 from slipping and ensuring transmission efficiency and grinding stability. Through the dual effects of external cooling and back jet cooling, as well as the continuous self-cleaning of the sticking rod 31, this equipment effectively solves the problem of uneven cooling in the grinding arc area in the prior art, as well as the problem of reduced grinding capacity and thermal damage caused by chip blockage of the abrasive belt 26. It achieves uniform cooling, efficient chip removal, and continuous self-cleaning of the sticking rod 31, thereby improving the quality and efficiency of roller polishing.

[0051] like Figure 7 and Figure 8 As shown, a circular hole is coaxially opened at the right end of the shaft post 30, and an adhesive rod 31 is inserted into the circular hole. A disc 310 is coaxially fixedly installed on the adhesive rod 31. Limiting posts 311 are uniformly fixedly installed at the left end of the disc 310 along its circumference. Limiting holes 300 corresponding to the limiting posts 311 are opened on the shaft post 30. The limiting posts 311 are magnetically attracted to the inner wall of the limiting holes 300.

[0052] like Figure 3 , Figure 4 and Figure 7 As shown, a fixing frame 32 located above the adhesive rod 31 is fixedly installed on the fixing plate 11. A scraper 33 is fixedly installed on the fixing frame 32. The lower part of the scraper 33 is evenly provided with comb teeth, which are tangentially attached to the adhesive rod 31.

[0053] like Figure 1 and Figure 7 As shown, the linkage 6 includes synchronous pulleys 60 fixedly installed on the shaft column 30 and the roller shaft 25, and a transmission belt 61 is connected between the two synchronous pulleys 60.

[0054] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, during actual operation, the synchronous wheel 60 fixedly installed on the roller 25 rotates accordingly, and drives the synchronous wheel 60 on the shaft 30 to rotate through the transmission belt 61, so that the shaft 30 and the adhesive rod 31 installed on it rotate at a speed matching the movement direction of the sanding belt 26. The outer layer material of the adhesive rod 31 is an adhesive polymer material, which keeps in contact with the processing surface of the sanding belt 26, and adheres the chips and impurities that have been loosened by the jet to the surface of the sanding belt 26.

[0055] As the adhesive stick 31 rotates continuously, debris gradually accumulates on its surface. A scraper 33, fixedly mounted on a bracket 32 ​​above the adhesive stick 31, has evenly spaced comb teeth at its lower part that tangentially adhere to the surface of the adhesive stick 31. When the adhesive stick 31 passes the scraper 33, the comb teeth scrape away the debris adhering to the surface of the adhesive stick 31, restoring a clean adhesive surface and achieving continuous self-cleaning. The scraped debris falls under gravity into an external collection container (not shown in the figure) below the scraper 33.

[0056] After prolonged use, the outer layer material of the adhesive stick 31 will need to be replaced due to wear or decreased adhesion. The adhesive stick 31 can be quickly disassembled and assembled through a magnetic adsorption structure: a circular hole is coaxially opened at the right end of the shaft post 30, and the adhesive stick 31 is inserted into the circular hole. The limiting post 311 is magnetically adsorbed with the inner wall of the limiting hole 300. When replacing, the old adhesive stick 31 can be removed by manually pulling the adhesive stick 31 outward to overcome the magnetic attraction. The limiting post 311 of the new adhesive stick 31 is aligned with the limiting hole 300 and pushed in. The magnetic force automatically attracts and locks it in place, without the need for tools.
