Description

Technical Field

[0001] This application relates to the technical field of cold pressing equipment, and in particular to a cold pressing equipment for diamond grinding wheel production. Background Technology

[0002] Diamond grinding wheels are circular bonded abrasive tools with a central through hole, made from diamond abrasive as raw material and using metal powder, resin powder, ceramic, or electroplated metal as binders.

[0003] When diamond grinding wheels are cold-pressed, the mixed metal powder raw materials need to be pressed. For example, Chinese patent CN116141217A discloses a cold-pressing device for the production of metal-bonded diamond grinding wheels. This device features a rotatable cold-pressing disc that rotates relative to the lower mold. This allows the raw material on the cold-pressing disc to be flattened without affecting the use of the lower mold. The hydraulic telescopic cylinder moves the upper mold downwards, simultaneously driving the drive component. This design effectively solves the problem of manual flattening before pressing, which is time-consuming and difficult to achieve even flattening.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Currently, diamond grinding wheel production mostly adopts the integral pressing method. Although this can improve pressing efficiency, this pressing method causes the raw material on the outer side of the grinding wheel to be easily squeezed by high pressure. This forces the binder in the raw material to flow outward, resulting in insufficient binder in the central area. This causes the edge of the grinding wheel to expand, while the center contracts due to insufficient pressure. Consequently, it is easy to cause uneven density distribution of the grinding wheel, with the outer ring having the highest powder density and the density gradually decreasing closer to the center. Moreover, the raw material will undergo elastic compression and plastic deformation under high pressure, and will rebound after the pressure is released. The difference in the amount of rebound between the inner and outer layers due to integral pressing can easily lead to internal stress concentration, forming microcracks or pores. This makes the grinding wheel prone to local breakage or chipping during grinding, seriously affecting the processing accuracy and life. Summary of the Invention

[0005] To address the problem that diamond grinding wheels are susceptible to high-pressure extrusion during cold pressing, which forces the binder in the raw material to flow outward, resulting in insufficient binder in the central area, causing the grinding wheel edges to expand while the center contracts due to insufficient pressure, thus easily leading to uneven density distribution of the grinding wheel and seriously affecting processing accuracy and lifespan, this application provides a cold pressing equipment for diamond grinding wheel production.

[0006] The cold pressing forming equipment for diamond grinding wheel production provided in this application adopts the following technical solution: A cold pressing forming device for diamond grinding wheel production includes a forming support, a cold pressing plate and a cold pressing seat movably disposed on the forming support, a cold pressing groove disposed on the cold pressing seat, a filling assembly for adding grinding wheel raw material to the cold pressing groove, and a cold pressing assembly for cold pressing the grinding wheel raw material in the cold pressing groove. The cold pressing assembly includes multiple cold pressing top rings movably mounted on the cold pressing plate, multiple cold pressing bottom rings movably mounted on the cold pressing base, an extrusion component for sequentially raising and lowering the multiple cold pressing top rings, a stamping component for sequentially raising and lowering the multiple cold pressing bottom rings, an adjustment component for adjusting the raising and lowering range of the multiple cold pressing top rings, a switching component for adjusting the raising and lowering range of the multiple cold pressing bottom rings, a synchronization component for synchronously driving the extrusion component and the stamping component, and a discharge component for discharging the grinding wheel raw material from the cold pressing tank. The discharge component is driven by the switching component. The packing assembly includes a packing element, a measuring element for adjusting the amount of grinding wheel material added to the connecting hose, a rotating element for rotating the cold press seat, and a lifting element for raising and lowering the cold press plate. The measuring element is automatically driven by the adjusting element.

[0007] By adopting the above technical solutions, the most common pressing method for grinding wheel raw materials during production is usually unidirectional pressing. Although this pressing method is simple to operate, it will lead to uneven density distribution of the grinding wheel. The density is high in the area close to the punch and low in the area far from the punch. This density gradient will cause the grinding wheel to warp, deform, or even crack after sintering. In addition, the hardness and wear resistance of different parts of the grinding wheel are inconsistent, which makes the grinding wheel have a high risk of breakage during use and affects the service life of subsequent diamond grinding wheels. Diamond grinding wheel sizes are typically identified by their diameter. Given a fixed diameter, different thicknesses are often required to accommodate various machining needs. Thick wheels are used for high cutting efficiency and good heat dissipation, thin wheels for high-precision machining or small-mass dressing, and medium wheels for versatility, balancing cutting efficiency and machining accuracy. However, existing cold-pressing equipment is not ideal for adjusting the amount of raw material and the groove thickness to achieve the desired wheel thickness, thus necessitating the production of wheels of varying thicknesses. In this process, different cold pressing equipment is required for processing, and workers need to adjust the amount of raw material added and the size of the pressing groove according to the different thicknesses of the grinding wheel. This not only increases the labor intensity of the workers but also reduces the work efficiency. Moreover, the frequent adjustments by the workers increase the complexity of the operation and the possibility of errors. If the workers adjust the amount of raw material added or the size of the pressing groove incorrectly, the quality of the processed grinding wheel will be seriously reduced, causing the manufactured grinding wheel to be scrapped, resulting in cost losses and failing to guarantee the effect of cold pressing of the grinding wheel. If grinding wheels of different thicknesses are processed on different cold pressing equipment, not only will the equipment investment and maintenance costs increase, but the production efficiency of the grinding wheel will also be affected. The filling assembly allows for the addition of grinding wheel material to the cold pressing tank. The amount of material added can be precisely controlled according to the required thickness and model of the diamond grinding wheel, preventing over- or under-addition and ensuring the effective pressing of the diamond grinding wheel. This also avoids waste of grinding wheel material. The cold pressing assembly allows for preliminary pre-pressing of all grinding wheel material in the tank, and can simultaneously press diamond grinding wheels of different thicknesses. This expands the application range of the cold pressing equipment, reduces operational complexity, and prevents mismatches between the amount of grinding wheel material added and the pressure applied during layered pressing, ensuring the pressing effect for grinding wheels of different thicknesses. Multiple cold pressing bottom rings and multiple cold pressing top rings sequentially and synchronously extrude layer by layer, effectively pressing the grinding wheel in the cold pressing tank. The grinding wheel material is extruded layer by layer from the outside in during pressing. This prevents uneven distribution of the binder in the grinding wheel material due to high pressure on the outside during pressing, which would result in a dense edge and a loose center. This allows for effective pressure transmission to the central area, ensuring a high degree of uniform density of the grinding wheel material from the outside to the inside, thus guaranteeing the quality of the diamond. Simultaneously, bidirectional extrusion of the grinding wheel material ensures uniform density distribution during pressing, maximizing the compression of both the top and bottom of the material. This prevents uneven distribution of the material during pressing, which could lead to inconsistent hardness and wear resistance across different parts of the grinding wheel, thereby extending its service life. The discharge device, in conjunction with the switching device, pushes the cold-pressed grinding wheel material out of the cold pressing tank, enabling rapid discharge of the grinding wheel material.

[0008] Optionally, the stamped part includes multiple compression springs and a first inner rod fixed in the cold pressing base, and two sets of fixed wedges movably disposed in the cold pressing base. The multiple compression springs are respectively fixedly connected to multiple cold pressing bottom rings. The multiple cold pressing bottom rings are all located in the cold pressing groove. The multiple cold pressing bottom rings are respectively a bottom outer ring, a bottom middle ring, and a bottom inner ring. The bottom middle ring is located between the bottom outer ring and the bottom inner ring. The bottom outer ring and the bottom inner ring are both movably connected to the bottom middle ring. The two sets of fixed wedges are movably fitted with the multiple cold pressing bottom rings. Each set of fixed wedges has three wedges. The thickness of the three fixed wedges is different. The two sets of fixed wedges are arranged symmetrically. The three fixed wedges in each set are respectively a first wedge, a second wedge, and a third wedge.

[0009] By adopting the above technical solution, the stamping part and the synchronizing part can extrude multiple cold-pressed bottom rings layer by layer. When the synchronizing part drives the two sets of fixed wedges to move relative to each other, the inclined surface of the fixed wedges can push multiple cold-pressed bottom rings upward in sequence, so that multiple compression springs are in a stretched state in sequence. With the extrusion part, the grinding wheel material in the cold pressing groove can be extruded layer by layer from the outside to the inside.

[0010] Optionally, the switching component includes two first turntables rotatably disposed within the cold pressing base, two first square rods and a first rotating rod, two movable screw plates movably disposed within the cold pressing base, and a drive motor fixed to the left movable screw plate. The two first turntables are rotatably connected to the two movable screw plates respectively, the two sets of fixed wedges are fixedly connected to the two first turntables respectively, the two first square rods are fixedly connected to the two first turntables respectively, the left first turntable is fixedly connected to the output shaft of the drive motor, and both first square rods are slidably connected to the first rotating rod.

[0011] By adopting the above technical solution, the switching component can adjust the position of the two sets of fixed wedges according to the required thickness of the grinding wheel material. The drive motor can sequentially drive the two first turntables, two first square rods, a first rotating rod, and the two sets of fixed wedges to rotate. The position of the first wedge, the second wedge, and the third wedge in each set of fixed wedges can be adjusted so that when the grinding wheel material is being pressed in layers, the designated fixed wedges can be controlled to press multiple cold-pressed bottom rings layer by layer. When pressing a thinner grinding wheel, two first wedges can be used to press multiple cold-pressed bottom rings layer by layer in sequence. When pressing a moderately thick grinding wheel, two second wedges can be used to press multiple cold-pressed bottom rings layer by layer in sequence. When pressing a thicker grinding wheel, two third wedges can be used to press multiple cold-pressed bottom rings layer by layer in sequence.

[0012] Optionally, the extrusion component includes multiple telescopic springs and a second inner rod fixed within the cold-press plate, a fixing groove disposed within the cold-press plate, and two sets of connecting wedges movably disposed within the cold-press plate. The multiple telescopic springs are respectively fixedly connected to multiple cold-press top rings, all of which are located in the fixing groove. The multiple cold-press top rings are respectively an outer top ring, a middle top ring, and an inner top ring. The middle top ring is located between the outer top ring and the inner top ring. Both the outer top ring and the inner top ring are movably connected to the middle top ring. The two sets of connecting wedges are movably fitted with the multiple cold-press top rings. Each set of connecting wedges consists of three wedges, each with a different thickness. The two sets of connecting wedges are arranged symmetrically. Each set of three connecting wedges consists of a fourth wedge, a fifth wedge, and a sixth wedge. The first wedge and the fourth wedge have the same thickness, the second wedge and the fifth wedge have the same thickness, and the third wedge and the sixth wedge have the same thickness.

[0013] By adopting the above technical solution, the extrusion component and the synchronization component can extrude multiple cold-pressed top rings layer by layer. When the synchronization component drives the two sets of connecting wedges to move relative to each other, the inclined surface of the connecting wedges can push multiple cold-pressed top rings to move downwards in sequence, so that multiple telescopic springs are in a stretched state in sequence. With the stamping component, the grinding wheel material in the cold pressing groove can be extruded layer by layer from the outside to the inside.

[0014] Optionally, the adjusting component includes two second turntables rotatably disposed within the cold press plate, two second square rods and a second rotating rod, two movable push plates movably disposed within the cold press plate, ring springs respectively fixed to the two movable push plates, and a servo motor fixed to the left movable push plate. Both ring springs are fixedly connected to the cold press plate, the two second turntables are rotatably connected to the two movable push plates respectively, the two sets of connecting wedges are fixedly connected to the two second turntables respectively, the two second square rods are fixedly connected to the two second turntables respectively, the left second turntable is fixedly connected to the output shaft of the servo motor, and both second square rods are slidably connected to the second rotating rod.

[0015] By adopting the above technical solution, the adjusting component can adjust the position of the two sets of connecting wedges according to the required thickness of the grinding wheel material. The servo motor can sequentially drive the two second turntables, two second square rods, the second rotating rod, and the two sets of connecting wedges to rotate. The position of the fourth, fifth, and sixth wedges in each set of connecting wedges can be adjusted so that when the grinding wheel material is being pressed in layers, the designated connecting wedges can be controlled to press multiple cold-pressing top rings layer by layer. When pressing a thinner grinding wheel, two fourth wedges can be used to press multiple cold-pressing top rings layer by layer in sequence. When pressing a moderately thick grinding wheel, two fifth wedges can be used to press multiple cold-pressing top rings layer by layer in sequence. When pressing a thicker grinding wheel, two sixth wedges can be used to press multiple cold-pressing top rings layer by layer in sequence.

[0016] Optionally, the synchronizing element includes a bidirectional motor fixed on the cold press base and two threaded rods rotatably mounted on the cold press base. The two threaded rods are respectively fixedly connected to the two output ends of the bidirectional motor, and the two threaded rods are respectively threadedly connected to two movable screw plates. Each of the two movable push plates is provided with a limit slot, and the two movable screw plates are respectively movably engaged with the two limit slots.

[0017] By adopting the above technical solution, the synchronizing component can drive the extrusion and stamping components synchronously. The bidirectional motor can drive two threaded rods to rotate. When the two threaded rods rotate, they can drive two movable screw plates, two first turntables, two first square rods, two discharge blocks, two sets of fixed wedges, two movable push plates, two second turntables, two second square rods, and two sets of connecting wedges to move relative to each other. Through the synchronous movement of the two sets of fixed wedges and the two sets of connecting wedges, multiple cold-pressing bottom rings and multiple cold-pressing top rings can be pushed to press the grinding wheel material in the cold-pressing tank layer by layer from the outside to the inside. The bottom outer ring and top outer ring can press the outermost grinding wheel material first, then the bottom middle ring and top middle ring can press the grinding wheel material in the middle position, and finally the bottom inner ring and top inner ring can press the innermost grinding wheel material, thus achieving the purpose of pressing the grinding wheel material layer by layer.

[0018] Optionally, the lifting component includes a hydraulic rod fixed to the forming support, and the cold pressing plate is fixedly connected to the output end of the hydraulic rod.

[0019] By adopting the above technical solution, the lifting component can perform preliminary overall pressing of the grinding wheel material in the cold pressing tank, and at the same time control the distance between the discharge head and the cold pressing tank. The hydraulic rod can sequentially drive the cold pressing plate, multiple cold pressing top rings and the discharge head to move up and down. The downward movement of multiple cold pressing top rings, in conjunction with multiple cold pressing bottom rings, can perform preliminary pre-pressing of all the grinding wheel material in the cold pressing tank.

[0020] Optionally, the discharge component includes discharge blocks fixed on two first turntables respectively, and the two discharge blocks are movably fitted with multiple cold-pressed bottom rings, and the two discharge blocks are arranged symmetrically.

[0021] By adopting the above technical solution, the discharge component can quickly remove the pressed grinding wheel material from the cold pressing tank to facilitate the processing of the next grinding wheel material. After the grinding wheel material is pressed, the switching component sequentially drives the two first turntables, two first square rods, a first rotating rod, two discharge blocks, and two sets of fixed wedges to rotate, so that the two discharge blocks abut against multiple cold pressing bottom rings. When the two discharge blocks rotate, they can push the multiple cold pressing bottom rings to move further upward. The multiple cold pressing bottom rings can push the cold-pressed grinding wheel material out of the cold pressing tank, completing the rapid discharge of the grinding wheel material.

[0022] Optionally, the filling component includes an electric push rod and a connecting hose fixed to the cold press plate, a support frame movably disposed on the cold press plate, and a discharge head communicating with the connecting hose. The discharge head is fixedly connected to the support frame, and the support frame is fixedly connected to the output end of the electric push rod. The rotating component includes a motor fixed to the forming support, and the cold pressing base is fixedly connected to the output end of the motor.

[0023] By adopting the above technical solution, the filling component, together with the rotating component, can evenly add the grinding wheel material into the cold pressing tank. First, the electric push rod drives the support frame and the discharge head to move in sequence, moving the discharge head to the top of the cold pressing tank. Then, the feeding machine can put the grinding wheel material into the inner side of the cold pressing tank through the connecting hose and the discharge head in sequence. At the same time, the motor can drive the cold pressing base and the cold pressing tank to rotate in sequence. When the cold pressing tank rotates, the material is evenly placed into the inner side of the cold pressing tank in conjunction with the material discharge from the discharge head, ensuring that the grinding wheel material in the cold pressing tank is evenly fed.

[0024] Optionally, the control component includes a control valve fixed to the connecting hose, a third rod fixed to the control valve, and a round rod fixed to the second turntable on the right side. The round rod is slidably connected to the third rod, the third rod is rotatably connected to the cold pressing plate, and the round rod is rotatably connected to the movable push plate on the right side.

[0025] By adopting the above technical solution, the control component can adjust the opening size of the control valve, and control the amount of grinding wheel material added according to the thickness to be processed. When the adjustment component is driven, it can drive the round rod and the third rod to rotate in sequence. When the round rod rotates, it can adjust the opening size of the control valve. When a thinner grinding wheel needs to be pressed, the opening of the control valve will be smaller; when a medium-thickness grinding wheel needs to be pressed, the opening of the control valve will be moderate; and when a thicker grinding wheel needs to be pressed, the opening of the control valve will be larger. The opening size of the control valve can be automatically adjusted according to the different models and thicknesses of the grinding wheel to be processed, avoiding the addition of too much or too little grinding wheel material.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The filling components, in conjunction with the rotating and lifting components, ensure that the discharge head accurately places the material into the cold pressing tank during feeding, preventing the grinding wheel material from being placed outside the cold pressing tank and ensuring the effectiveness of the grinding wheel material feeding. This allows the grinding wheel material to be evenly placed into the cold pressing tank, ensuring uniform distribution of the grinding wheel material within the tank, thus guaranteeing the effectiveness of subsequent grinding wheel material pressing. After the grinding wheel material is placed in the cold pressing tank, the lifting components drive multiple cold pressing top rings to move downwards, coordinating with multiple cold pressing bottom rings. This allows for preliminary pre-pressing of all the grinding wheel material in the cold pressing tank, removing large particle gaps and forming a uniform density distribution. This provides a stable foundation for subsequent layered pressing, ensuring the effectiveness of subsequent grinding wheel material cold pressing. 2. Based on the required thickness of the diamond grinding wheel to be cold-pressed, the switching component can adjust the positions of the two sets of fixed wedges, and the adjusting component can adjust the positions of the two sets of connecting wedges. This allows for layer-by-layer pressing of the grinding wheel material, controlling two designated fixed wedges to press multiple cold-pressed bottom rings layer by layer, and controlling two designated connecting wedges to press multiple cold-pressed top rings layer by layer. This facilitates the pressing of diamond grinding wheels of different thicknesses, expanding the application range of the cold-pressing equipment and eliminating the need for different cold-pressing devices. For grinding wheels of different thicknesses, the control components, in conjunction with the adjustment components, can automatically adjust the opening size of the control valve according to the type and thickness of the grinding wheel to be processed. This allows the feeding machine to precisely control the amount of grinding wheel material added based on the required thickness of the diamond grinding wheel, avoiding adding too much or too little material and ensuring the pressing effect of the diamond grinding wheel. When adjusting the two sets of connecting wedges, the control valve can also be adjusted simultaneously to reduce the complexity of operation and avoid mismatch between the amount of grinding wheel material added and the force during layered pressing, thus ensuring the pressing effect of grinding wheels of different thicknesses. 3. After the positions of the two sets of fixed wedges and the two sets of connecting wedges are adjusted, the synchronizing component, in conjunction with the stamping and extruding components, can push multiple cold-pressing bottom rings upward and multiple cold-pressing top rings downward. Through the sequential and synchronous layer-by-layer extrusion of multiple cold-pressing bottom rings and multiple cold-pressing top rings, the grinding wheel material in the cold-pressing groove can be extruded layer by layer from the outside to the inside, achieving the purpose of layer-by-layer extrusion of the grinding wheel material. Finally, the overall pressing, through uniform pressure and long holding time, ensures the overall density of the grinding wheel, avoiding uneven distribution of the binder in the grinding wheel material due to high-pressure extrusion on the outside during pressing, which would result in a dense edge and a loose center. This ensures that the density of the grinding wheel material is highly uniform from the outside to the inside, ensuring that each ring of powder in the grinding wheel material is fully compressed. Sufficient compaction is essential to minimize stress concentration caused by uneven rebound forces on the inner and outer sides of the grinding wheel material after pressing. This reduces the likelihood of cracks and pores in the grinding wheel, ensuring diamond quality. Furthermore, bidirectional extrusion of the grinding wheel material ensures uniform density distribution during pressing, guaranteeing that both the top and bottom of the material are compressed. Uneven distribution during pressing leads to inconsistent hardness and wear resistance across different parts of the grinding wheel, reducing breakage and extending its lifespan. The discharge mechanism, in conjunction with a switching mechanism, pushes the cold-pressed grinding wheel material out of the cold-pressing tank, facilitating rapid discharge for the next batch of material and improving processing efficiency.

[0042] The implementation principle of a cold pressing forming device for diamond grinding wheel production according to an embodiment of this application is as follows: (1) According to the required thickness of the diamond grinding wheel to be cold-pressed, the drive motor 34 can sequentially drive two first turntables 13, two first square rods 32, a first rotating rod 20, two discharge blocks 12 and two sets of fixed wedges 11 to rotate. When the two sets of fixed wedges 11 rotate, the positions of the first wedge, the second wedge and the third wedge in each set of fixed wedges 11 can be adjusted so that when the grinding wheel material is being pressed in layers, the designated fixed wedges 11 can be controlled to press multiple cold-pressed bottom rings 7 layer by layer. The servo motor 14 can sequentially drive two second turntables 16, two second square rods 31, a second rotating rod 19 and two sets of connecting wedges 17 to rotate. When the two sets of connecting wedges 17 rotate, the positions of the fourth wedge, the fifth wedge and the sixth wedge in each set of connecting wedges 17 can be adjusted so that when the grinding wheel material is being pressed in layers, the designated connecting wedges 17 can be controlled to press multiple cold-pressed top rings 6 layer by layer. Thus, by this method, when a thinner grinding wheel needs to be pressed, two first wedges can be used. Multiple cold-pressed bottom rings 7 are pressed layer by layer in sequence. Two fourth wedges can be used to press multiple cold-pressed top rings 6 layer by layer in sequence. When a moderately sized grinding wheel is required, two second wedges can be used to press multiple cold-pressed bottom rings 7 layer by layer in sequence. Two fifth wedges can be used to press multiple cold-pressed top rings 6 layer by layer in sequence. When a thicker grinding wheel is required, two third wedges can be used to press multiple cold-pressed bottom rings 7 layer by layer in sequence. Two sixth wedges can be used to press multiple cold-pressed top rings 6 layer by layer in sequence. Furthermore, depending on the type and thickness of the grinding wheel to be processed, when pressing the grinding wheel raw material layer by layer, two designated fixed wedges 11 are controlled to press multiple cold-pressed bottom rings 7 layer by layer, and two designated connecting wedges 17 are controlled to press multiple cold-pressed top rings 6 layer by layer in sequence. This allows for the pressing of diamond grinding wheels of different thicknesses, which can improve the application range of the cold-pressing forming equipment and eliminate the need to use different cold-pressing equipment to process grinding wheels of different thicknesses. (2) Simultaneously, when the second turntable 16 on the right rotates, it can also sequentially drive the round rod 24 and the third rod 25 to rotate. When the third rod 25 rotates, it can adjust the opening size of the control valve 30. Therefore, when a thinner grinding wheel needs to be pressed, the angle at which the second turntable 16 on the right rotates the third rod 25 is smaller, and thus the opening of the control valve 30 will also be smaller. When a moderately thick grinding wheel needs to be pressed, the angle at which the second turntable 16 on the right rotates the third rod 25 is moderate, and thus the opening of the control valve 30 will also be moderate. When a thicker grinding wheel needs to be pressed, the angle at which the second turntable 16 on the right rotates the third rod 25 is larger, and thus the opening of the control valve 30 will also be larger. The opening size of the control valve 30 can be automatically adjusted according to the different models and thicknesses of the diamond grinding wheels to be processed. This allows the feeder to accurately control the amount of grinding wheel material added when feeding the grinding wheel material, based on the required thickness of the diamond grinding wheel. This avoids adding too much or too little grinding wheel material, ensuring the pressing effect of the diamond grinding wheel. When processing grinding wheels of different thicknesses, the control valve 30 can also be adjusted synchronously when adjusting the two sets of connecting wedges 17, reducing the complexity of operation and avoiding mismatch between the amount of grinding wheel material added and the force when pressing the grinding wheel material in layers. This ensures the pressing effect of grinding wheels of different thicknesses and reduces the chance of grinding wheel scrap. (3) When cold pressing the grinding wheel material, the discharge head 29 can be moved horizontally by the electric push rod 26. The discharge head 29 can be moved to the top of the cold pressing groove of the cold pressing seat 4. The feeding machine can put the grinding wheel material into the inside of the cold pressing groove through the connecting hose 28 and the discharge head 29 in sequence. At the same time, the motor 5 can drive the cold pressing seat 4, the cold pressing groove, the bidirectional motor 8, the two threaded rods 9, the two movable screw plates 10, the two first turntables 13, the two first square rods 32, the first rotating rod 20, the multiple compression springs 23, and the multiple cold pressing bottom rings 7 in sequence. The first inner rod 33 and the two sets of fixed wedges 11 rotate. When the cold pressing trough rotates, it cooperates with the material discharge head 29 to make the grinding wheel material evenly put into the inner side of the cold pressing trough, ensuring that the grinding wheel material in the cold pressing trough is evenly fed, so as to ensure the pressing effect of the subsequent grinding wheel material. After the grinding wheel material in the cold pressing trough is filled, the motor 5 is stopped first, and then the electric push rod 26 can drive the support frame 27 and the material discharge head 29 to move horizontally in sequence, moving the material discharge head 29 away from the top of the cold pressing trough, so as to avoid the subsequent grinding wheel material being obstructed by the material discharge head 29 during pressing. (4) The hydraulic rod 2 can sequentially drive the cold pressing plate 3, the fixed groove, multiple telescopic springs 22, multiple cold pressing top rings 6, the second inner rod 21, two movable push plates 15, two second turntables 16, two second square rods 31, the second rotating rod 19, the servo motor 14, two ring springs 18, two sets of connecting wedges 17, the electric push rod 26, the support frame 27, the connecting hose 28, the discharge head 29, the control valve 30, the round rod 24 and the third rod 25 to move up and down, which can adjust the height of the cold pressing plate 3 and the discharge head 29, so that the height of the discharge head 29 can be controlled when feeding, and the discharge head 29 can be accurately placed into the cold pressing groove when feeding, avoiding the grinding wheel material being placed outside the cold pressing groove, and ensuring the effect of grinding wheel material feeding; (5) After the grinding wheel material is put into the cold pressing tank, the hydraulic rod 2 drives multiple cold pressing top rings 6 to move downwards and cooperate with multiple cold pressing bottom rings 7 to perform preliminary pre-pressing on all the grinding wheel material in the cold pressing tank, remove the gaps between large particles in the grinding wheel material, form a uniform density distribution, provide a stable foundation for subsequent layer pressing, and ensure the effect of subsequent cold pressing of grinding wheel material. (6) After the positions of the two sets of fixed wedges 11 and the two sets of connecting wedges 17 are adjusted, when the cold pressing plate 3 moves downward to drive multiple cold pressing top rings 6 to pre-press the grinding wheel material, the two movable screw plates 10 will respectively engage with the limiting slots on the two movable push plates 15. After the grinding wheel material is pre-pressed, the two threaded rods 9 can be driven to rotate by the bidirectional motor 8. When the two threaded rods 9 rotate, they can respectively drive the two movable screw plates 10, the two first turntables 13, the two first square rods 32, the two discharge blocks 12, the two sets of fixed wedges 11, the two movable push plates 15, the two second turntables 16, and the two second square rods 17. When rod 31 and two sets of connecting wedges 17 move relative to each other, the annular springs 18 on the two movable push plates 15 are in a stretched state. When the two adjusted fixed wedges 11 move relative to each other, the inclined surface of the fixed wedges 11 can sequentially push multiple cold-pressed bottom rings 7 upward, so that multiple compression springs 23 are in a stretched state. When the two adjusted connecting wedges 17 move relative to each other, the inclined surface of the connecting wedges 17 can sequentially push multiple cold-pressed top rings 6 downward, so that multiple telescopic springs 22 are in a stretched state. Thus, through the multiple cold-pressed bottom rings 7 and multiple cold-pressed top rings 6... The sequential, synchronous, layer-by-layer extrusion process allows for the extrusion of the grinding wheel material within the cold pressing tank from the outside in. This involves the bottom and top outer rings simultaneously pressing the outermost grinding wheel material first, followed by the bottom and top middle rings pressing the middle grinding wheel material, and finally the bottom and top inner rings pressing the innermost grinding wheel material. This achieves the goal of layer-by-layer extrusion of the grinding wheel material. Ultimately, the overall pressing, through uniform pressure and a long holding time, ensures the overall density of the grinding wheel. This prevents uneven distribution of the binder in the grinding wheel material due to high-pressure extrusion on the outer edges, which could lead to a dense edge and a loose center. Ensuring a high degree of uniform density in the grinding wheel raw material from the outside to the inside ensures that each ring of powder is fully compacted. This minimizes the risk of internal stress concentration due to differences in resilience between the inner and outer sides of the raw material after pressing, reducing the likelihood of cracks and pores in the grinding wheel and thus guaranteeing diamond quality. Furthermore, bidirectional extrusion of the grinding wheel raw material ensures uniform density distribution during pressing, maximizing the compression of both the top and bottom of the raw material. This prevents uneven distribution of the raw material during pressing, which can lead to inconsistent hardness and wear resistance across different parts of the grinding wheel, reducing the chance of breakage and extending its service life. (7) After the grinding wheel material is pressed, the hydraulic rod 2 can sequentially drive the cold pressing plate 3, the two movable push plates 15 and the multiple cold pressing top rings 6 to move upward, so that the multiple cold pressing top rings 6 can be separated from the pressed grinding wheel material. The two movable push plates 15 will also be separated from the two movable screw plates 10 respectively, so that the two movable push plates 15 lose their limit. Through the elastic force of the two ring springs 18, the two movable push plates 15, the two second turntables 16, the two second square rods 31 and the two sets of connecting wedges 17 can be driven to move in opposite directions, so that the connecting wedges 17 can be separated from the multiple cold pressing top rings 6. Then, through the elastic force of the multiple telescopic springs 22, the two sets of connecting wedges 17 and the multiple cold pressing top rings 6 can be restored to their initial state, so as to facilitate the cold pressing of the next material. (8) The cold-pressed grinding wheel material is located inside the cold pressing tank. At this time, the drive motor 34 can sequentially drive the two first turntables 13, the two first square rods 32, the first rotating rod 20, the two discharge blocks 12, and the two sets of fixed wedges 11 to rotate, so that the two discharge blocks 12 abut against the multiple cold pressing bottom rings 7. When the two discharge blocks 12 rotate, they can push the multiple cold pressing bottom rings 7 to move further upward, and then the multiple cold pressing bottom rings 7 can push the cold-pressed grinding wheel material out of the cold pressing tank, thus completing the rapid discharge of the grinding wheel material. After the grinding wheel material is processed, the two threaded rods 9 can be driven to rotate by the bidirectional motor 8. When the two threaded rods 9 rotate, they can drive the two movable screw plates 10, the two first turntables 13, the two first square rods 32, the two discharge blocks 12 and the two sets of fixed wedges 11 to move in opposite directions. This causes the two discharge blocks 12 to separate from the multiple cold-pressed bottom rings 7. Then, through the elastic force of the multiple compression springs 23, the multiple cold-pressed bottom rings 7 can be restored to their original positions to facilitate the cold pressing of the next material, thereby improving the efficiency of grinding wheel material processing.
