Description

Technical Field

[0001] This invention relates to the field of hydraulic forming technology for grinding wheels, and specifically proposes a demolding device for hydraulic forming of grinding wheels. Background Technology

[0002] Grinding wheels, also known as bonded abrasives, are abrasives made by bonding ordinary abrasive grains into a specific shape (mostly circular with a central through-hole) using a binder, giving them a certain strength. They are the most important type of abrasive in grinding processes. The forming of a grinding wheel generally includes the following steps: Raw material preparation: Prepare the raw materials for the abrasive and binder; Material mixing: Mix the abrasive and binder together in a certain proportion; Mold filling: Fill the mixed material into the grinding wheel mold; Pressing and forming: Place the filled mold into a press and compact the material under certain pressure; Hardening and sintering: Place the formed grinding wheel into a furnace for hardening and sintering; Cooling and dressing: After the grinding wheel cools, remove it and dress it.

[0003] However, the following problems still exist in the current process of manufacturing grinding wheels: 1. In the process of manufacturing grinding wheels, a release agent is applied to the mold in advance to facilitate demolding. The application of the release agent is usually done manually. Manual application of the release agent reduces work efficiency and increases labor costs. Moreover, manual application of the release agent cannot accurately control the amount of release agent used, which easily leads to uneven application and affects the molding quality of the grinding wheel.

[0004] 2. After the grinding wheel is formed, the traditional method is to directly eject the formed grinding wheel and remove the upper and lower mold bases to complete the grinding wheel unloading. Directly ejecting the formed grinding wheel and separating the mold from the grinding wheel may damage the grinding wheel or cause certain defects on the surface of the formed grinding wheel, thus failing to guarantee the accuracy of the grinding wheel forming.

[0005] Therefore, in order to avoid affecting the forming quality and work efficiency of the grinding wheel during the manufacturing process, the present invention provides a grinding wheel hydraulic forming demolding device. Summary of the Invention

[0006] Therefore, it is necessary to provide a hydraulic forming and demolding device for grinding wheels, which aims to solve the problems of existing technology affecting the forming quality and work efficiency of grinding wheels during the manufacturing process.

A stepped rod is fixedly installed on the top of the driving member. Limiting grooves are symmetrically opened on the left and right sides of the side wall of the annular cylinder. An annular push plate is slidably arranged on the annular cylinder. A limiting block that cooperates with the limiting groove is fixedly installed on the inner side wall of the annular push plate. An arc-shaped stepped groove that is slidably connected to the stepped rod is symmetrically opened on the left and right sides of the bottom of the annular push plate. The top left and right sides of the annular push plate are symmetrically fixedly connected to the bottom of the lower circular plate through cylindrical rods.

[0014] According to one embodiment of the present invention, the extrusion assembly includes an annular frame with an opening facing downwards, which is fixedly installed by a rotating rod rotatably disposed on the left bottom of a horizontal plate. A pressing plate with an annular structure is fixedly installed at the bottom of the annular frame. An annular groove is formed at one end of the pressing plate located on the inner annular surface of the annular frame.

[0016] According to one embodiment of the present invention, the stirring assembly includes a second motor fixedly installed at the bottom right side of a horizontal plate, a disc block fixedly installed at the bottom of the output shaft of the second motor, a stirring rod uniformly fixedly installed at the bottom of the disc block along the circumference, and a plurality of stirring blades uniformly fixedly installed at the bottom of the stirring rod along the circumference.

[0017] The above-described one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects:

[0018] According to the molding mechanism provided in the first aspect of the present invention, before molding the grinding wheel, the operation of applying the release agent can be completed by moving the circular plate, which can achieve rapid application. Compared with manual application, this method can greatly improve work efficiency, save time and labor costs, and can more accurately control the amount of release agent, avoid excessive use of release agent, reduce waste, and at the same time ensure the uniformity of release agent during application, avoiding uneven application, which would affect the molding quality of the grinding wheel.

[0019] Furthermore, according to the cooperation of the molding mechanism and the moving mechanism provided in the second aspect embodiment of the present invention, when the grinding wheel is unloaded after molding, the moving component first drives the pressed grinding wheel to rotate left and right, so that the grinding wheel separates from the molding cylinder first, which can reduce the adhesion force. By setting the first vibration component and the second vibration component, the surface in contact with the grinding wheel is separated first by vibration, which can ensure the accuracy of separation and ensure that the grinding wheel can be demolded smoothly during molding, avoiding the occurrence of adhesion or damage on the surface of the grinding wheel.

[0020] Furthermore, the stirring assembly provided in the third aspect embodiment of the present invention can uniformly stir the material for making the grinding wheel inside the molding cylinder. Stirring can uniformly mix the various components in the grinding wheel material and eliminate air bubbles, which helps to ensure the uniformity of the material inside the grinding wheel and improve the quality and performance of the grinding wheel. The binder in the grinding wheel material is usually mixed with the granular material. The stirring process can increase the contact area between the binder and the granular material and improve the activity of the binder. At the same time, stirring can also effectively promote the more uniform dispersion of the particles in the grinding wheel material.

[0021] 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

Detailed Implementation

[0033] 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.

[0034] See Figure 1 A grinding wheel hydraulic forming demolding device includes a worktable 1, on which forming mechanisms 2 are symmetrically arranged on the left and right sides of the top of the worktable 1, and a moving mechanism 3 is arranged between the two forming mechanisms 2 on the top of the worktable 1.

[0035] See Figure 1 and Figure 2The molding mechanism 2 includes a fixed frame 20 mounted on a workbench 1. The fixed frame 20 consists of a circular block with an annular structure and two vertical plates with arc-shaped structures on the left and right. A molding cylinder 21 with an annular structure is fixedly installed on the inner wall of the circular block with an annular structure. A top rod 22 is fixedly installed at the center of the molding cylinder 21 on the top of the workbench 1. An annular cylinder 23 is rotatably mounted on the top of the workbench 1 and sleeved on the outside of the top rod 22. An annular plate 24 is slidably mounted on the top rod 22 near the top. Circular plates 25 of the same size are symmetrically arranged on the upper and lower sides of the annular plate 24. An applicator 26 for applying release agent to the inner wall of the molding cylinder 21 is mounted on the lower circular plate 25. A first vibration assembly 27 for easy demolding is also arranged between the upper and lower circular plates 25. A moving assembly 28 for controlling the rotation of the annular cylinder 23 is mounted on the workbench 1. A drive assembly 29 for controlling the up and down movement of the circular plate 25 is also mounted on the workbench 1.

[0036] See Figure 2 The moving mechanism 3 includes an intermittent motor fixedly installed at the top center of the workbench 1. The output shaft of the intermittent motor is fixedly installed with a support column 31. The top of the support column 31 is provided with an installation groove. A cylinder is fixedly installed in the installation groove. A horizontal plate 32 is fixedly installed at the moving end of the cylinder. A second vibration component 34 for easy demolding is provided on the left bottom of the horizontal plate 32 through the extrusion component 33. A stirring component 35 for stirring the mixed material for making the grinding wheel is provided on the right bottom of the horizontal plate 32.

[0037] In its initial state, the drive assembly 29 positions the upper circular plate 25 above the molding cylinder 21 and the application assembly 26 within the molding cylinder 21 (e.g., Figure 9(As shown) At this time, the cooperation of the drive component 29 and the moving component 28 allows the application component 26 to evenly apply the release agent to the inner wall of the molding cylinder 21. The release agent can effectively reduce the adhesion between the mold and the grinding wheel, making it easier for the molded grinding wheel to detach from the mold, which helps protect the shape and surface quality of the mold. After the release agent is applied to the inner wall of the molding cylinder 21, the circular plate 25 located on the upper side is positioned inside the molding cylinder 21. At this time, the mixed material to be used to make the grinding wheel can be placed into the molding cylinder 21 on the left fixed frame 20. After placement, start... The cylinder moves the horizontal plate 32, along with the stirring assembly 35, downwards into the molding cylinder 21 containing the mixed material for making the grinding wheel. The stirring assembly 35 evenly mixes and flattens the mixed material into the molding cylinder 21, facilitating subsequent pressing and molding. After the stirring assembly 35 finishes mixing, the cylinder moves the horizontal plate 32 back to its original position. At this point, the intermittent motor is activated, causing the horizontal plate 32 on the support column 31 to rotate intermittently. This positions the stirring assembly 35 on the right and the extrusion assembly 33 on the left, allowing the grinding wheel to be formed. The mixed material is placed into the molding cylinder 21 on the right-side fixed frame 20. Next, the cylinder is activated for the second time, causing the horizontal plate 32 to move the extrusion assembly 33 into the molding cylinder 21 containing the mixed material on the left. Simultaneously, the stirring assembly 35 moves downwards to the molding cylinder 21 containing the mixed material for making the grinding wheel on the right. This allows the extrusion assembly 33 to press and shape the mixed material on the left, while the stirring assembly 35 stirs and flattens the mixed material on the right. After the mixed material on the left is pressed and shaped, the moving assembly 28 first moves the pressed material... The grinding wheel is twisted left and right, so that the formed grinding wheel is no longer in close contact with the inner wall of the forming cylinder 21, allowing the grinding wheel to separate from the forming cylinder 21 first. This reduces adhesion and friction during separation, thus avoiding damage to the grinding wheel surface and maintaining the forming accuracy. Then, the second vibration component 34 set on the extrusion component 33 makes the formed grinding wheel no longer in close contact with the extrusion component 33. At the same time, the stirring component 35 completes the mixing of the material on the right side. After stirring, the cylinder is activated to return to its original position. Finally, the set drive component 29 drives the formed grinding wheel to move upward, returning it to its original state (e.g., Figure 9 As shown), at this time, the No. 1 vibration component 27 makes the formed grinding wheel no longer stick tightly to the upper circular plate 25, which facilitates the feeding of the grinding wheel. After feeding, the release agent is evenly applied to the inner wall of the forming cylinder 21 by the coating component 26, and the mixed material to be made into the grinding wheel is placed into the forming cylinder 21 coated with the release agent. Finally, the above steps are repeated from the position of starting the intermittent motor.

[0038] See Figure 2 and Figure 8 The stirring assembly 35 includes a second motor fixedly installed at the bottom right side of the horizontal plate 32. A disc block 351 is fixedly installed at the bottom of the output shaft of the second motor. A stirring rod 352 is evenly fixedly installed at the bottom of the disc block 351 along the circumference. A plurality of stirring blades 353 are evenly fixedly installed at the bottom of the stirring rod 352 along the circumference.

[0039] After the stirring assembly 35 moves downward into the molding cylinder 21 containing the mixed material for making the grinding wheel, the second motor is started, causing the disc block 351 to simultaneously drive multiple stirring rods 352 to rotate. This, in turn, causes the stirring rods 352 to drive the stirring blades 353 to rotate, thereby causing the stirring blades 353 to uniformly stir the grinding wheel material inside the molding cylinder 21. Stirring can evenly mix the various components in the grinding wheel material and eliminate air bubbles, which helps to ensure the uniformity of the material inside the grinding wheel and improve the quality and performance of the grinding wheel. The binder in the grinding wheel material is usually mixed with granular materials. The stirring process can increase the contact area between the binder and the granular materials, improve the activity of the binder, and at the same time, stirring can also effectively promote the more uniform dispersion of particles in the grinding wheel material.

[0040] See Figure 4 , Figure 5 and Figure 7 The coating component 26 includes an arc-shaped groove evenly opened circumferentially on the top of the lower circular plate 25. A hollow, arc-shaped material holding plate 261 is slidably disposed in the arc-shaped groove. An openable cover plate is provided on the top of the material holding plate 261. A release agent is placed inside the material holding plate 261. The outer arc surface of the material holding plate 261 is evenly provided with leakage holes that communicate with the hollow part of the material holding plate 261. A replaceable coating cloth 262 is installed on the outer arc surface of the material holding plate 261. A ring-shaped movable plate 263 is fixedly installed on the top of the lower circular plate 25 by multiple support springs. The left and right sides of the top of the lower circular plate 25 are symmetrically fixedly connected to the bottom of the movable plate 263 by electric push rods. Multiple swing blocks 264 are evenly hinged circumferentially on the outer wall of the movable plate 263 by pins. The end of the swing block 264 away from the movable plate 263 is hinged to the inner arc surface of the material holding plate 261.

[0041] When it is necessary to apply release agent to the inner wall of the molding cylinder 21, the electric push rod is first activated, causing the moving plate 263 to move downward. At this time, under the limit of the arc groove, the moving plate 263 simultaneously causes multiple swing blocks 264 to squeeze multiple material holding plates 261 to open outward in sync, so that the coating cloth 262 on the material holding plate 261 comes into contact with the inner wall of the molding cylinder 21. At this time, with the cooperation of the set drive component 29 and the moving component 28, the coating cloth 262 on the material holding plate 261 evenly applies the release agent to the inner wall of the molding cylinder 21, so as to avoid the grinding wheel being difficult to demold after molding. After the coating is completed, the electric push rod returns to its original position, so that the coating cloth 262 on the material holding plate 261 no longer comes into contact with the inner wall of the molding cylinder 21.

[0042] See Figure 8 The moving component 28 includes a fixed block 281 fixedly installed on the workbench 1 near the front side. A rack plate 282 is fixedly installed on the rear end face of the fixed block 281 via an electric telescopic rod. A rotating gear 283 that meshes with and drives the rack plate 282 is fixedly installed on the annular cylinder 23.

[0043] See Figure 2 The driving assembly 29 includes driving components symmetrically fixedly installed on the top of the worktable 1 on the left and right sides of the annular cylinder 23. A stepped rod 291 is fixedly installed on the top of the driving component. Limiting grooves are symmetrically opened on the left and right sides of the side wall of the annular cylinder 23. An annular push plate 292 is slidably arranged on the annular cylinder 23. A limiting block that cooperates with the limiting groove is fixedly installed on the inner side wall of the annular push plate 292. Arc-shaped stepped grooves that slide and connect with the stepped rod 291 are symmetrically opened on the left and right sides of the bottom of the annular push plate 292. The top left and right sides of the annular push plate 292 are symmetrically fixedly connected to the bottom of the lower circular plate 25 through cylindrical rods 293.

[0044] When the application component 26 is used to apply the release agent to the inner wall of the molded cylinder 21, the electric telescopic rod is activated to drive the rack plate 282 to move back and forth, which in turn causes the rotating gear 283 to drive the annular cylinder 23 to rotate. During the rotation, the cylindrical rod 293 on the annular push plate 292 drives the lower circular plate 25 to rotate. At this time, by sliding the step rod 291 set in the arc-shaped stepped groove, the circular plate 25 drives the application component 26 to rotate and apply the release agent to the inner wall of the molded cylinder 21. At the same time, the drive component (electric push rod or electric telescopic rod) is activated to move downward at a constant speed, which in turn causes the cylindrical rod 293 on the annular push plate 292 to drive the lower circular plate 25 to move downward at a constant speed. This causes the circular plate 25 to drive the application component 26 to gradually apply the release agent downward to the inner wall of the molded cylinder 21. By moving the circular plate 25, the application process can be completed. The application of release agent allows for rapid application, significantly improving work efficiency and saving time and labor costs compared to manual application. It also allows for more precise control of the release agent dosage, preventing overuse and reducing waste. After the grinding wheel is pressed into the material inside the molding cylinder 21, the electric telescopic rod is activated to move the rack plate 282 back and forth, causing the rotating gear 283 to rotate the annular cylinder 23. This causes the formed grinding wheel to no longer adhere tightly to the inner wall of the molding cylinder 21. Simultaneously, when the second vibration component 34 prevents the formed grinding wheel from adhering tightly to the extrusion component 33, the driving component (electric push rod or electric telescopic rod) moves upward at a constant speed. This causes the cylindrical rod 293 on the annular push plate 292 to move the lower circular plate 25 upward at a constant speed, which in turn moves the formed grinding wheel upward at a constant speed, causing the grinding wheel to detach from the molding cylinder 21.

[0045] See Figure 2 and Figure 3 The extrusion assembly 33 includes an annular frame 331 with an opening facing downwards, which is fixedly installed by a rotating rod that is rotatably set at the bottom left side of the horizontal plate 32. A pressing plate 332 with an annular structure is fixedly installed at the bottom of the annular frame 331. An annular groove is opened at one end of the top of the pressing plate 332 located on the inner annular surface of the annular frame 331. An annular limiting plate 333 is fixedly installed on the inner annular surface of the annular frame 331. A second impact plate 334 is fixedly installed at the bottom of the annular limiting plate 333 by multiple second spring rods. Multiple square blocks 335 with a wedge-shaped structure that penetrate the annular limiting plate 333 are fixedly installed on the top of the second impact plate 334 along the circumferential direction.

[0046] Continue reading Figure 2 and Figure 3The second vibration component 34 includes a sliding groove evenly opened circumferentially on the inner end face of the annular frame 331. A structural block 341 that cooperates with the square block 335 is slidably connected in the sliding groove by a compression spring. A ring-shaped stabilizing plate 342 is provided in the annular frame 331. Multiple push blocks 343 that are fixedly connected to the structural block 341 are evenly slidably arranged on the stabilizing plate 342 along the circumferential direction. One end of the push block 343 located in the annular surface of the stabilizing plate 342 is wedge-shaped. A trapezoidal block 344 that cooperates with the push block 343 is fixedly installed at the center of the inner end face of the annular frame 331 by a driving component.

[0047] By fixing the pressing plate 332 at the bottom of the annular frame 331, when the cylinder moves the horizontal plate 32 downward, the annular frame 331 drives the pressing plate 332 to press the material for making the grinding wheel mixed inside the forming cylinder 21. After the moving component 28 causes the formed grinding wheel to no longer be tightly attached to the inner wall of the forming cylinder 21, the driving component (electric push rod or electric telescopic rod) drives the trapezoidal block 344 to move up and down reciprocally. When moving downward, the trapezoidal block 344 pushes the push rod... Block 343 opens synchronously, causing pusher block 343 to push multiple structural blocks 341 to compress the compression spring. When moving upward, under the reaction force of the compression spring, structural block 341 causes multiple pusher blocks 343 to synchronously retract and return to their original positions. During this process, square block 335 pushes the second impact plate 334 to impact the pressing plate 332 back and forth, causing the pressing plate 332 to generate a certain amount of aftershock. This facilitates the separation of the grinding wheel from the pressing plate 332 through vibration.

[0048] By using vibration to separate the pressing plate 332 and the grinding wheel, the accuracy of the separation can be ensured. Vibration can help loosen the contact between the grinding wheel and the pressing plate 332 and ensure that there is no pressure between the grinding wheel and the pressing plate 332. This can ensure that the grinding wheel can be demolded smoothly during molding and avoid the occurrence of adhesion or damage to the surface of the grinding wheel.

[0049] See Figure 4 , Figure 5 and Figure 6The first vibration assembly 27 includes an annular groove at the bottom of the upper circular plate 25. A first impact plate 271, located within the annular groove, is fixedly mounted on the top of the lower circular plate 25 via multiple first spring rods. A first wedge block 272 is uniformly fixedly mounted circumferentially at the bottom of the first impact plate 271. Displacement grooves are uniformly opened circumferentially on the top of the lower circular plate 25. A rectangular block 273 is slidably disposed within the displacement groove via a return spring. A round-headed plate 274 is fixedly mounted on the top of the rectangular block 273. The top of the head plate 274 is fixedly installed with a second wedge block 275 that cooperates with the first wedge block 272. The annular plate 24 is rotatably provided with a flower-shaped plate 276 that cooperates with multiple round head plates 274. The bottom of the irregular plate 276 is fixedly installed with an annular block 277. The driven gear 278 is fixedly installed on the annular block 277. The top of the lower circular plate 25 is fixedly installed near the left side with a first motor. The output shaft of the first motor is fixedly installed with a driving gear 279 that meshes with the driven gear 278.

[0050] When the grinding wheel is no longer in close contact with the pressing plate 332, and the drive assembly 29 causes the formed grinding wheel to move upward (e.g. Figure 1 As shown), starting the first motor causes the driving gear 279 to drive the annular block 277 on the driven gear 278 to rotate, which in turn causes the annular block 277 to drive the irregular plate 276 to rotate. During the rotation of the irregular plate 276, when the arc-shaped part of the round head plate 274 contacts the concave part of the irregular plate 276, the rectangular block 273, under the action of the return spring, causes the second wedge block 275 on the round head plate 274 to press the first wedge block 272. When the arc-shaped part of the round head plate 274 contacts the concave part of the irregular plate 276... When the convex part of 276 contacts, the round head plate 274 drives the rectangular block 273 to squeeze the return spring, thereby causing the second wedge block 275 to return to its original position. At this time, under the action of the first spring rod, the first wedge block 272 always cooperates with the second wedge block 275. In this process, the first wedge block 272 pushes the first impact plate 271 to hit the upper circular plate 25 back and forth, so that the upper circular plate 25 generates a certain aftershock, so that the grinding wheel is no longer in close contact with the upper circular plate 25.

[0051] In specific work:

[0052] In the first step, in the initial state, the drive assembly 29 positions the upper circular plate 25 above the molding cylinder 21, and positions the coating assembly 26 inside the molding cylinder 21 (e.g., Figure 9(As shown) At this time, the cooperation of the drive component 29 and the moving component 28 enables the coating component 26 to evenly coat the release agent on the inner wall of the molding cylinder 21. After the release agent is coated on the inner wall of the molding cylinder 21, the circular plate 25 located on the upper side is placed inside the molding cylinder 21. At this time, the mixed material to be made into a grinding wheel can be placed into the molding cylinder 21 on the left fixed frame 20. After placement, the cylinder is activated so that the horizontal plate 32 drives the stirring component 35 to move downward into the molding cylinder 21 containing the mixed material to be made into a grinding wheel. The stirring component 35 evenly stirs and mixes the mixed material to be made into a grinding wheel and spreads it into the molding cylinder 21. After the stirring component 35 has finished stirring, the cylinder drives the horizontal plate 32 to return to its original position.

[0053] The second step involves starting the intermittent motor, which causes the horizontal plate 32 on the support column 31 to rotate intermittently. This positions the mixing component 35 on the right and the extrusion component 33 on the left. The mixed material to be used to make the grinding wheel is then placed into the forming cylinder 21 on the right-side fixed frame 20. Next, the cylinder is activated a second time, causing the horizontal plate 32 to move the extrusion component 33 into the forming cylinder 21 containing the mixed material on the left. Simultaneously, the mixing component 35 moves downwards to the forming cylinder 21 containing the mixed material for making the grinding wheel on the right, allowing the extrusion component 33 to press and shape the mixed material on the left. This allows the mixing component 35 to stir and flatten the mixed material on the right side. After the mixed material on the left side is pressed into shape, the moving component 28 first drives the pressed grinding wheel to rotate left and right, so that the formed grinding wheel is no longer in close contact with the inner wall of the forming cylinder 21. Then, the second vibration component 34 set on the extrusion component 33 makes the formed grinding wheel no longer in close contact with the extrusion component 33. At the same time, the mixing component 35 completes the stirring of the mixed material on the right side. After stirring, the cylinder is started to return to its original position. Finally, the driving component 29 drives the formed grinding wheel to move upward, returning it to its original state (e.g., Figure 9 As shown), at this time, the No. 1 vibration component 27 makes the formed grinding wheel no longer stick tightly to the upper circular plate 25, which facilitates the feeding of the grinding wheel. After feeding, the release agent is evenly applied to the inner wall of the forming cylinder 21 by the coating component 26, and the mixed material to be made into the grinding wheel is placed into the forming cylinder 21 that has been coated with the release agent.

[0054] The third step is to repeat the second step. The left and right positions of the stirring component 35 and the extrusion component 33 can be changed according to the position of each rotation.
