Abstract
Description
Technical Field
[0001] This invention relates to the field of casting equipment technology, specifically to an integrated intelligent casting equipment for bearing rings. Background Technology
[0002] In the rapid development of industrial manufacturing, bearing rings, as key components, directly affect the performance of related equipment and manufacturing costs due to their casting quality and production efficiency. Traditional casting equipment suffers from problems such as low mold assembly precision, difficulty in controlling molten metal forming, and uneven cooling leading to fluctuations in casting quality, making it difficult to meet the modern industrial demand for high-precision, high-efficiency, and intelligent production of bearing rings.
[0003] For example, the national authorized patent announcement number CN115780782A discloses an integrated casting equipment, including a base, a mounting frame fixedly mounted on the top of the base, a moving mold assembly mounted on the top of the mounting frame, and a fixed mold assembly mounted on the top of the base; several demolding components are mounted on the outer side of the mounting frame, and the demolding components are equidistantly distributed around the mounting frame; a driving assembly is mounted on the top of the base, which can drive the demolding components. This invention uses the cooperation of the fixed mold and the moving mold to ensure the complete forming of the casting in the casting cavity, and then uses the driving assembly to cause the demolding components to eject the casting, allowing the casting to be smoothly ejected from the side.
[0004] However, the aforementioned integrated casting equipment requires the equipment to stop and wait for demolding and cooling of the special mold cavity for bearing rings. A large amount of time is consumed in non-casting operations, which greatly reduces the number of casting batches that can be completed per unit time and significantly reduces the overall production efficiency. It is difficult to meet the needs of large-scale and efficient bearing ring production. Due to the intermittent stoppage of the equipment, it is difficult to form a continuous and stable production cycle, which brings difficulties to the management of production planning, material distribution, and personnel scheduling. It is easy to have a situation where production is not well connected and resources are both idle and wasted. Summary of the Invention
[0005] The purpose of this invention is to provide an integrated intelligent casting equipment for bearing rings, so as to solve the problems mentioned in the background art, which are caused by the inability to achieve continuous casting operations, resulting in low production efficiency, increased costs, and difficulties in production management.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] An integrated intelligent casting equipment for bearing rings includes: a gantry frame, a first motor fixedly installed on one side of the gantry frame, a bidirectional lead screw fixedly installed at one end of the output shaft of the first motor, the end of the bidirectional lead screw away from the first motor being rotatably installed in a support plate, the support plate being fixedly installed on the upper surface of the gantry frame, and transmission blocks threadedly installed on the outer surfaces of both ends of the bidirectional lead screw, the lower ends of the two sets of transmission blocks sliding through the upper surface of the gantry frame into the interior of the gantry frame, and H-shaped plates fixedly installed on the lower surfaces, rotating rods fixedly installed at both ends of the H-shaped plates, and casting mechanisms rotatably installed on the outer surfaces of each set of rotating rods;
[0008] In this configuration, the other ends of each pair of horizontally opposing casting mechanisms are rotatably connected together, allowing the casting mechanisms to slide inward synchronously via the threaded transmission of the H-shaped plates and the bidirectional lead screws. This enables the two sets of H-shaped plates to drive the four casting mechanisms to slide inward synchronously. Two of the casting mechanisms are then driven to flip and fold inward relative to each other and can be assembled into a mold as they are pushed. At the same time, the two sets of pushed H-shaped plates also press against the two ends of the two casting mechanisms to clamp them inward. The other two casting mechanisms are driven to flip inward and outward relative to each other and are pushed to flip into a V-shape, thus turning the mold cavity so that it faces outward.
[0009] The mold assembly formed by the two casting mechanisms is flush with one of the two sets of filling pipes. The two sets of filling pipes are installed on both ends of the upper surface of the gantry frame. A ball three-way valve is installed between the two sets of filling pipes. The other end of the ball three-way valve can be connected to the molten metal supply equipment.
[0010] The two sets of H-shaped plates are each fixedly equipped with a cooling mechanism at both ends. This allows the cooling mechanism to be driven to touch one side of each of the two sets of casting mechanisms when the H-shaped plates push the two sets of casting mechanisms together, thus accelerating the solidification process during the injection of molten metal.
[0011] Preferably, guide rail blocks are fixedly installed at both ends of the upper surface of the two sets of H-shaped plates. The guide rail blocks are slidably installed on the lower half of the outer surface of the guide rail strip, and the guide rail strip is fixedly installed at both ends of the lower inner surface of the gantry frame.
[0012] Preferably, the outer surface of the bidirectional lead screw is fitted with a protective cover, which is fixedly installed on the upper surface of the gantry frame.
[0013] Preferably, the casting mechanism includes a first template and a second template, which are rotatably mounted on the outer surfaces of rotating rods fixedly mounted at both ends of the H-shaped plate. The other ends of the first template and the second template, which are rotatably mounted at both ends of the two sets of horizontally opposite H-shaped plates, are rotatably connected to the other ends of the first template and the second template on another set of H-shaped plates.
[0014] Preferably, a transmission column is rotatably mounted on the lower surface of both sets of the second templates. The transmission column slides within the U-shaped shell, and a threaded rod is rotatably mounted within the U-shaped shell. The threaded rod passes through both sets of transmission columns and one end is fixedly connected to the output shaft of the second motor. The second motor is fixedly mounted at one end of the U-shaped shell. Thus, when the bidirectional lead screw drives the two sets of H-shaped plates to move towards each other, the threaded rod also drives the two sets of transmission columns to slide to one side within the U-shaped shell. The sliding transmission column pulls the second template and drives the first template, forming a rotation fulcrum through the rotating rod, allowing them to be linked and hinged so that the four sets of templates can complete the flipping action synchronously. Finally, under the constraint of the guide rail, precise mold alignment is achieved, allowing the second template and the first template to drive the bearing ring special mold cavity opened at one end to assemble into a mold groove. The other set of the second template and the first template are pushed out to the outer end of the gantry to form a V-shape, thereby flipping the bearing ring special mold cavity to face outward.
[0015] Preferably, after the bearing rings are cast, the first and second motors can be synchronously reversed to drive the two sets of H-shaped plates to slide outwards synchronously, so as to stretch the first and second templates into a horizontal position. Then, the first and second motors can be restarted again, and the second motor can be reversed, so that the uncast first and second templates can be flipped into the gantry to complete the mold closing. The cast first and second templates will have the side with the special mold cavity for the bearing rings pushed to the outer end of the gantry to form a V shape again.
[0016] The first and second templates are provided with filling ports on their upper surfaces. The filling ports are connected to the special mold cavity for bearing rings, so that when the first and second templates are pushed together, the filling ports will also be driven together and can be perpendicular to one of the filling tubes.
[0017] Preferably, the cooling mechanism includes two sets of heat-conducting plates, which are embedded and fixedly installed at both ends of an H-shaped plate. Each heat-conducting plate has four sets of copper pipes inserted inside it, and the other end of each set of copper pipes extends out of the heat-conducting plate and is connected to a converging pipe. The two sets of converging pipes are fixedly installed at one end of the H-shaped plate, and a T-shaped pipe is installed between the upper and lower surfaces of the two sets of converging pipes. The remaining set of pipes of the two sets of T-shaped pipes is connected to the inlet and outlet of a water pump, respectively. The water pump is fixedly installed at one end of the H-shaped plate.
[0018] Preferably, the copper pipe stores coolant, so that the water pump can supply the coolant into the heat-conducting plate through the copper pipe. The coolant absorbs heat and then flows through the copper pipe into the converging pipe, and is finally drawn back by the water pump inlet to form a circulation.
[0019] Preferably, the heat-conducting plate can fit into the heat-conducting groove as the H-shaped plate is pushed, and the heat-conducting groove is formed on one side of the first template and the second template.
[0020] Preferably, a heat dissipation fin is fixedly installed at one end of the heat-conducting plate, and a cooling fan is fixedly installed at one end of the heat dissipation fin.
[0021] Compared with the prior art, the beneficial effects of the present invention are:
[0022] 1. Through the design of the first motor, filling pipe, ball-type three-way valve, double-acting screw, H-shaped plate, transmission block, cooling mechanism, and casting mechanism, in use, the first motor and casting mechanism can be started simultaneously. The started first motor will drive the double-acting screw to rotate. Since the screw threads at both ends of the double-acting screw turn in opposite directions, the two sets of transmission blocks with threads installed on their outer surfaces will slide synchronously inward along the screw axis when the screw rotates. This allows the two sets of transmission blocks to drive the two sets of H-shaped plates fixed to them to slide synchronously towards the center within the gantry. During the movement, the rotating rods fixed at both ends drive the casting mechanism mounted on its outer surface to move together. Because the other ends of each pair of laterally opposite casting mechanisms are connected by rotation, the H-shaped plate, as it slides inward, is driven by the casting mechanism, causing two of the casting mechanisms to flip and fold inward relative to each other, gradually assembling into a complete mold. Simultaneously, the other two casting mechanisms flip outward relative to each other due to the pushing direction, ultimately unfolding in a V-shape, turning the mold cavity so that its facing direction is outward. And when the mold formed by the two sets of casting mechanisms... When the entire assembly is flush with one of the sets of injection pipes installed at both ends of the upper surface of the gantry frame, the molten metal supply equipment will inject molten metal into the mold through the selected injection pipe by connecting to the ball three-way valve. At this time, the cooling mechanism fixedly installed at both ends of the H-shaped plate will press against one side of the two casting mechanisms as the H-shaped plate moves, thereby transferring low temperature to the casting mechanism and accelerating the solidification of the molten metal in the mold. After the casting has cooled and solidified, the first motor and the casting mechanism can reverse together, causing the bidirectional lead screw to rotate in the opposite direction, thereby driving the transmission block and the H-shaped plate to move outward synchronously. The sliding mechanism gradually stretches out the two casting mechanisms after casting and causes them to flip outward into a V-shape due to continuous pushing, facilitating demolding. At the same time, the other two casting mechanisms in the V-shape can be pushed inward to flip and close, starting a new round of casting and achieving continuous production. This dual-station alternating casting design eliminates the idle time of traditional equipment waiting for demolding and cooling, realizing uninterrupted casting operation. When one set of molds is casting, the other set is simultaneously demolded and cooled, ensuring seamless production cycle and meeting the needs of large-scale production of bearing rings.
[0023] 2. Through the design of the second motor, threaded rod, first template, second template, special mold cavity for bearing rings, filling port, and transmission column, during the casting of bearing rings, the first and second motors can be started simultaneously to drive the double-acting lead screw and threaded rod to rotate respectively. When the double-acting lead screw rotates, it drives two sets of H-shaped plates to slide synchronously inward along the screw axis. Simultaneously, the threaded rod drives two sets of transmission columns to slide to one side within the U-shaped shell. As the transmission columns are pushed by the threaded rod, they simultaneously pull the second template to rotate around the rotating rod as a fulcrum. Through the hinge structure, the first template moves synchronously, ensuring that the first and second templates fold inwards synchronously. Guided by the guide rails and guide blocks, the H-shaped plates gradually push the two sets of templates until they fold and assemble together. Simultaneously, the two sets of H-shaped plates abut against one end of the first and second templates, clamping them together. After the first and second templates are assembled, the special mold cavity for bearing rings at one end is precisely assembled into a complete casting mold. The filling ports on the first and second molds will automatically align with the filling pipes due to the folding, thus completing the mold closing and preparing for casting. At the same time, another set of first and second molds will be pulled to the outer end of the gantry by the transmission column and gradually unfolded and flipped into a V shape. After the casting has solidified, the first and second motors can be controlled to reverse synchronously, so that the bidirectional screw drives the H-shaped plate to slide outward, and at the same time, the threaded rod pulls back to stretch both sets of first and second molds into a horizontal position. Then, the first and second motors can be restarted again, and the second motor can be reversed, so that the uncast first and second molds can be flipped into the gantry to complete the assembly and mold closing. The cast first and second molds will be pushed to the outer end of the gantry with the side with the special mold cavity for bearing rings, forming a V shape again for demolding. This achieves the synchronous operation of mold closing and casting and demolding and cleaning, without waiting for a single set of molds to cool and demold before starting the next cycle, greatly reducing non-production time and adapting to the continuous and large-scale production rhythm of bearing rings.
[0024] 3. Through the design of water pump, T-junction, converging pipe, copper pipe, heat-conducting plate, cooling fan, and heat dissipation fins, after the first and second templates are synchronously pushed inward and flipped to complete the assembly process, the two sets of H-shaped plates can drive the heat-conducting plates fixed on both sides to fit into the heat-conducting grooves opened at one end of the first and second templates. Then, the water pump can be started to pump out the coolant stored in the copper pipes, allowing it to be transported through the water pump outlet and T-junction to the converging pipe, and then distributed through the converging pipe to the four sets of copper pipes installed in the heat-conducting plate. When the copper pipe flows through the heat-conducting plate, the first and second molds can quickly absorb the heat generated during casting. After heat exchange, the coolant flows back to the converging pipe through the copper pipe, and then is drawn back through the water pump inlet via the tee pipe, realizing coolant circulation. At the same time, the heat dissipation fins at one end of the heat-conducting plate increase the heat dissipation area and work with the cooling fan to accelerate airflow, assisting the heat-conducting plate and copper pipe in heat dissipation, improving the cooling efficiency of the coolant, ensuring the continuous and stable operation of the cooling cycle, and providing support for the rapid removal of heat and accelerated solidification of the molten metal during the casting process of the bearing ring.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0036] Please see Figures 1-9 This embodiment provides an integrated intelligent casting equipment for bearing rings, including: a gantry frame 1, a first motor 101 fixedly installed on one side of the gantry frame 1, a bidirectional lead screw 106 fixedly installed at one end of the output shaft of the first motor 101, the end of the bidirectional lead screw 106 away from the first motor 101 being rotatably installed in a support plate 4, the support plate 4 being fixedly installed on the upper surface of the gantry frame 1, and transmission blocks 107 are threadedly installed on the outer surfaces of both ends of the bidirectional lead screw 106, and the lower ends of both sets of transmission blocks 107 slide through the upper surface of the gantry frame 1 to the interior of the gantry frame 1, and H-shaped plates 105 are fixedly installed on the lower surfaces, rotating rods 110 are fixedly installed at both ends of the H-shaped plates 105, and casting mechanism 3 is rotatably installed on the outer surface of each set of rotating rods 110;
[0037] In this configuration, the other ends of each pair of horizontally opposing casting mechanisms 3 are rotatably connected together, so that the casting mechanism 3 can be driven to slide inward synchronously through the threaded transmission of the H-shaped plate 105 and the double-acting screw 106. This allows the two sets of H-shaped plates 105 to drive the four sets of casting mechanisms 3 to slide inward synchronously. Two sets of casting mechanisms 3 will be driven to flip and fold inward relative to each other and can be assembled into a mold as they are pushed. At the same time, the two sets of pushed H-shaped plates 105 will also press against the two ends of the two sets of casting mechanisms 3 to clamp them inward. The other two sets of casting mechanisms 3 will be driven to flip inward and outward relative to each other and pushed to flip into a V-shape, so that the mold cavity is flipped to face outward.
[0038] Among them, the mold assembly formed by the two sets of casting mechanisms 3 will be flush with one of the two sets of filling pipes 103 at the same time, and the two sets of filling pipes 103 are installed on both ends of the upper surface of the gantry frame 1. A ball three-way valve 104 is installed between the two sets of filling pipes 103, and the other set of pipes of the ball three-way valve 104 can be connected to the molten metal supply equipment.
[0039] The two sets of H-shaped plates 105 are each fixedly equipped with a cooling mechanism 2. When the H-shaped plates 105 push the two sets of casting mechanisms 3 to flip and assemble together, the cooling mechanism 2 can be driven to touch one side of the two sets of casting mechanisms 3 respectively, so that the solidification can be accelerated during the process of injecting molten metal.
[0040] Among them, guide rail blocks 109 are fixedly installed at both ends of the upper surface of the two sets of H-shaped plates 105. The guide rail blocks 109 are slidably installed on the lower half of the outer surface of the guide rail 108. The guide rail 108 is fixedly installed at both ends of the inner lower surface of the gantry frame 1. The outer surface of the bidirectional lead screw 106 is fitted with a cover 102, which is fixedly installed on the upper surface of the gantry frame 1.
[0041] Through the design of the first motor 101, filling pipe 103, ball three-way valve 104, double-acting lead screw 106, H-shaped plate 105, transmission block 107, cooling mechanism 2, and casting mechanism 3, in use, the first motor 101 and casting mechanism 3 can be started simultaneously. The started first motor 101 will drive the double-acting lead screw 106 to rotate. Since the threads at both ends of the double-acting lead screw 106 turn in opposite directions, the two sets of transmission blocks 107 with threads installed on its outer surface will slide synchronously inward along the axis of the lead screw when the lead screw rotates. This allows the two sets of transmission blocks 107 to drive the two sets of H-shaped plates 105 fixedly connected to them to rotate. The gantry 1 slides synchronously towards the center, and during the movement of the H-shaped plate 105, the rotating rods 110 fixed at both ends drive the casting mechanism 3 rotatably mounted on its outer surface to move together. Because the other ends of each pair of laterally opposite casting mechanisms 3 are rotatably connected, the H-shaped plate 105, when sliding inward, is driven by the casting mechanisms 3, causing two of the casting mechanisms 3 to flip and fold inward relative to each other, gradually assembling into a complete mold assembly. Simultaneously, the other two casting mechanisms 3 will flip outward relative to each other due to the pushing direction, ultimately unfolding in a V-shape, turning the mold cavity to face outwards. And when the two sets of... When the mold assembly formed by the casting mechanism 3 is flush with one of the sets of injection pipes 103 inserted at both ends of the upper surface of the gantry frame 1, the molten metal supply equipment will inject molten metal into the mold through the selected injection pipe 103 by connecting with the ball three-way valve 104. At this time, the cooling mechanism 2, which is fixedly installed at both ends of the H-shaped plate 105, will press against one side of the two sets of casting mechanisms 3 as the H-shaped plate 105 moves, thereby transferring low temperature to the casting mechanism 3 and accelerating the solidification of the molten metal in the mold. After the casting has cooled and solidified, the first motor 101 and the casting mechanism 3 can reverse together, causing the bidirectional lead screw 106 to rotate in the opposite direction. This causes the transmission block 107 and the H-shaped plate 105 to slide outward synchronously, so that the two sets of casting mechanisms 3 that have been cast are gradually pulled out and will flip outward into a V shape due to continuous pushing, which facilitates demolding. At the same time, the molds of the other two sets of casting mechanisms 3 that are in the V shape can be pushed inward to flip and close the mold, and start a new round of casting, realizing continuous production. Moreover, through this dual-station alternating casting design, the idle time of waiting for demolding and cooling of traditional equipment is eliminated, realizing uninterrupted casting operation. When one set of molds is casting, the other set is demolded and cooled simultaneously, so that the production cycle is seamlessly connected, meeting the needs of large-scale production of bearing rings.
[0042] The casting mechanism 3 includes a first template 304 and a second template 305. The first template 304 and the second template 305 are respectively rotatably installed on the outer surface of the rotating rods 110 fixedly installed at both ends of the H-shaped plate 105. The other ends of the first template 304 and the second template 305 rotatably installed at both ends of the two sets of horizontally opposite H-shaped plates 105 are respectively rotatably connected to the other ends of the first template 304 and the second template 305 on another set of H-shaped plates 105.
[0043] Both sets of second templates 305 have rotatably mounted transmission columns 308 on their lower surfaces. The transmission columns 308 slide within a U-shaped shell 301. A threaded rod 303 is rotatably mounted within the U-shaped shell 301, and the threaded rod 303 threadedly passes through both sets of transmission columns 308, with one end fixedly connected to the output shaft of a second motor 302. The second motor 302 is fixedly mounted at one end of the U-shaped shell 301. Thus, when the bidirectional lead screw 106 drives the two sets of H-shaped plates 105 to move towards each other, the threaded rod 303 also drives the two sets of transmission columns 308 to slide to one side within the U-shaped shell 301. The sliding transmission column 308 pulls the second template 305 to drive the first template 304 and forms a rotation fulcrum through the rotating rod 110, so that the four sets of templates can be linked and the flipping action can be completed synchronously. Finally, under the constraint of the guide rail 108, the precise mold alignment is achieved, so that the second template 305 and the first template 304 can drive the bearing ring special mold cavity 306 opened at one end to be assembled into a mold groove. The other set of second template 305 and first template 304 will be pushed out to the outer end of the gantry 1 to form a V shape, so as to flip the bearing ring special mold cavity 306 to face the outward end.
[0044] After the bearing rings are cast, the first motor 101 and the second motor 302 can be synchronously reversed to drive the two sets of H-shaped plates 105 to slide outwards synchronously, so as to stretch the first template 304 and the second template 305 into a horizontal position. Then the first motor 101 and the second motor 302 can be restarted again, and the second motor 302 can be reversed, so that the uncast first template 304 and the second template 305 can be flipped into the gantry 1 to complete the mold closing. The cast first template 304 and the second template 305 will push the side with the special mold cavity 306 for the bearing rings to the outer end of the gantry 1 to form a V shape again.
[0045] The first template 304 and the second template 305 are both provided with filling ports 307 on their upper surfaces. The filling ports 307 are connected to the special mold cavity 306 for bearing rings. This allows the first template 304 and the second template 305 to be pushed and assembled together, and the filling ports 307 will also be assembled together and can be perpendicular to one of the filling tubes 103.
[0046] Through the design of the second motor 302, threaded rod 303, first template 304, second template 305, bearing ring special mold cavity 306, filling port 307, and transmission column 308, during the casting of bearing rings, the first motor 101 and the second motor 302 can be started simultaneously to drive the bidirectional lead screw 106 and the threaded rod 303 to rotate respectively. When the bidirectional lead screw 106 rotates, it drives two sets of H-shaped plates 105 to slide synchronously inward along the lead screw axis. At the same time, the threaded rod 303 drives the two sets of transmission columns 308 to slide to one side within the U-shaped shell 301. As the transmission columns 308 are pushed by the threaded rod 303, they are pulled together. The second template 305 rotates around the pivot rod 110, and the first template 304 moves synchronously through a hinge structure. This ensures that the first template 304 and the second template 305 fold inwards simultaneously. Guided by the guide rails 108 and 109, the H-shaped plates 105 gradually push the two sets of templates until they are folded and assembled together. As the first template 304 and the second template 305 are assembled, the two sets of H-shaped plates 105 will also abut against one end of the first template 304 and the second template 305 respectively, clamping the two sets of templates. After the first template 304 and the second template 305 are assembled, a special mold for bearing rings is opened at one end. Cavity 306 will be precisely assembled into a complete mold, while the filling ports 307 on the first mold 304 and the second mold 305 will automatically align with the filling pipe 103 due to folding, thus completing the mold closing and preparing for casting. At the same time, the other set of first mold 304 and second mold 305 will be pulled to the outer end of the gantry 1 by the transmission column 308 and gradually stretched and flipped into a V shape. After the casting has solidified, the first motor 101 and the second motor 302 can be controlled to reverse synchronously, so that the bidirectional screw 106 drives the H-shaped plate 105 to slide outward, and at the same time, the threaded rod 303 pulls back, so that both sets of first mold 304 and second mold 305 are stretched. In a horizontal position, the first motor 101 and the second motor 302 can be restarted, and the second motor 302 can be reversed. This allows the uncast first template 304 and the second template 305 to flip into the gantry 1 to complete the assembly and mold closing. The cast first template 304 and the second template 305 will push the side with the special mold cavity 306 for bearing rings to the outside of the gantry 1 to form a V shape again for demolding. This achieves the simultaneous execution of mold closing and casting and demolding and cleaning, without waiting for a single set of molds to cool and demold before starting the next cycle. This greatly reduces non-production time and adapts to the rhythm of continuous and large-scale bearing ring production.
[0047] The cooling mechanism 2 includes two sets of heat-conducting plates 205, which are embedded and fixedly installed at both ends of the H-shaped plate 105. Each heat-conducting plate 205 is fitted with four sets of copper pipes 204, and the other end of each set of copper pipes 204 extends out from the heat-conducting plate 205 and is connected to a converging pipe 203. The two converging pipes 203 are fixedly installed at one end of the H-shaped plate 105. A three-way pipe 202 is installed between the upper and lower surfaces of the two converging pipes 203. The remaining pipe of each of the two three-way pipes 202 is connected to the inlet and outlet of the water pump 201, respectively. The water pump 201 is fixedly installed at one end of the H-shaped plate 105.
[0048] The copper pipe 204 stores coolant, allowing the water pump 201 to supply the coolant into the heat-conducting plate 205 through the copper pipe 204. The coolant absorbs heat and then flows through the copper pipe 204 into the converging pipe 203, and is finally drawn back through the inlet of the water pump 201 to form a circulation. The heat-conducting plate 205 can fit into the heat-conducting groove 309 as the H-shaped plate 105 is pushed, and the heat-conducting groove 309 is opened on one side of the first template 304 and the second template 305. A heat dissipation fin 207 is fixedly installed at one end of the heat-conducting plate 205, and a cooling fan 206 is fixedly installed at one end of the heat dissipation fin 207.
[0049] Through the design of water pump 201, T-pipe 202, converging pipe 203, copper pipe 204, heat-conducting plate 205, cooling fan 206, and heat dissipation fins 207, after the first template 304 and the second template 305 are pushed inward and flipped to complete the assembly process, the two sets of H-shaped plates 105 can drive the heat-conducting plates 205 fixed on both sides to fit into the heat-conducting grooves 309 opened at one end of the first template 304 and the second template 305. Then, the water pump 201 can be started to pump out the coolant stored in the copper pipe 204, allowing it to be transported through the outlet of the water pump 201 and the T-pipe 202 to the converging pipe 203, and then distributed through the converging pipe 203 to the parts installed in the heat-conducting plates 205. Among the four sets of copper pipes 204, when the copper pipes 204 flow through the heat-conducting plate 205, the first template 304 and the second template 305 can quickly absorb the heat generated by the casting of the bearing ring. After the heat exchange is completed, the coolant flows back to the converging pipe 203 through the copper pipes 204, and then is drawn back through the water pump 201 inlet through the three-way pipe 202 to realize the circulation of coolant. At the same time, the heat dissipation fins 207 at one end of the heat-conducting plate 205 increase the heat dissipation area and, together with the cooling fan 206, accelerate the air flow, assisting the heat-conducting plate 205 and the copper pipes 204 in heat dissipation, improving the cooling efficiency of the coolant, ensuring the continuous and stable operation of the cooling cycle, and providing support for the rapid removal of heat and accelerated solidification of the molten metal during the casting process of the bearing ring.
[0050] Specifically, the integrated intelligent casting equipment for bearing rings in this embodiment also includes a dual-station time-temperature coordinated control method, the control equation of which is as follows:
[0051] ;
[0052] in:
[0053] : Complete cycle time of dual-station operation (s);
[0054] : Pouring time (s);
[0055] Total heat capacity of castings (J);
[0056] k: Equivalent heat transfer coefficient of the mold-heat-conducting plate system (W / (m²·K));
[0057] A: Effective heat transfer area (m²);
[0058] : Effective temperature difference (K) between the mold and the coolant;
[0059] Demolding time (s);
[0060] Cleaning and preparation time (s);
[0061] The mechanical synchronization compensation time (s) is determined by the linkage accuracy between the H-shaped plate movement and the template flipping mechanism.
[0062] Equation derivation process:
[0063] This equation is constructed based on the principle of thermal equilibrium and the dual-station temporal coupling constraint:
[0064] 1. Cooling time term: The time required for the casting to cool is obtained by simplifying the heat conduction equation:
[0065] ;
[0066] in m is the mass of the casting. For specific heat capacity, This is the difference between the pouring temperature and the demolding temperature.
[0067] 2. Process Time Item: Casting, demolding, and cleaning are sequential processes, and their total time is:
[0068] ;
[0069] 3. Dual-station collaborative constraint: To ensure seamless connection, the longer of the cooling time and process time determines the single-station occupancy period, i.e.:
[0070] ;
[0071] 4. Mechanical Synchronization Compensation: Due to the movement time of mechanisms such as H-shaped plates and template flipping, a synchronization compensation item needs to be added. This ensures that there are no conflicts in the connection between the two workstations.

[0086] 2. Substitute into the equation to calculate the current optimal value. ;

[0088] 4. The two stations alternate between pouring, cooling and demolding, and cleaning to achieve seamless connection.
[0089] Based on the above technical solution, the working steps of this solution are summarized as follows: During the casting of the bearing rings, the first motor 101 and the second motor 302 can be started simultaneously to drive the bidirectional lead screw 106 and the threaded rod 303 to rotate respectively. When the bidirectional lead screw 106 rotates, it drives two sets of H-shaped plates 105 to slide synchronously inward along the lead screw axis. Simultaneously, the threaded rod 303 drives two sets of transmission columns 308 to slide to one side within the U-shaped shell 301. During the process of the transmission columns 308 being pushed by the threaded rod 303, they simultaneously pull the second template 305 to rotate around the rotating rod 110 as a fulcrum. Through the hinge structure, the first template 304 moves synchronously, thereby ensuring that the first template 304 and the second template 305 fold inward synchronously. Guided by the guide rails 108 and 109, the H-shaped plates 105 gradually push the two sets of templates until they fold and assemble together. Simultaneously, as the first template 304 and the second template 305 assemble, the two sets of H-shaped plates 105 abut against one end of each template, clamping them together. At the same time, the two sets of H-shaped plates 105 also drive the heat-conducting plates 205 fixedly installed on both sides to fit into the heat-conducting grooves 309 at one end of the first template 304 and the second template 305. After the first template 304 and the second template 305 are assembled, the bearing ring-specific mold cavity 306 at one end is precisely assembled into a complete casting. The first template 304 and the second template 305... The filling port 307 will automatically align with the filling pipe 103 due to the folding, thus completing the mold closing and preparing for casting. After casting, the water pump 201 can be started to pump out the coolant stored in the copper pipe 204, allowing it to be transported through the outlet of the water pump 201 and the tee pipe 202 to the converging pipe 203. Then, through the converging pipe 203, it is distributed to the four sets of copper pipes 204 installed in the heat-conducting plate 205. When the copper pipes 204 flow through the heat-conducting plate 205, the first mold 304 and the second mold 305 can quickly absorb the heat generated by the casting of the bearing ring. After heat exchange, the coolant flows back to the converging pipe 203 through the copper pipes 204, and then is drawn back through the inlet of the water pump 201 through the tee pipe 202, realizing coolant circulation and quickly removing heat during the casting process of the bearing ring. The process involves increasing the volume and accelerating the solidification of the molten metal. Simultaneously, the other set of first mold plates 304 and 305 are pulled to the outer end of the gantry frame 1 by the transmission column 308 and gradually unfolded and flipped into a V-shape. After the casting has solidified, the first motor 101 and the second motor 302 can be controlled to reverse synchronously, so that the bidirectional lead screw 106 drives the H-shaped plate 105 to slide outward. At the same time, the pullback of the threaded rod 303 is coordinated to stretch both sets of first mold plates 304 and 305 into a horizontal position. Then, the first motor 101 and the second motor 302 can be restarted, and the second motor 302 can be reversed, so that the uncast first mold plates 304 and 305 can be flipped into the gantry frame 1 to complete the assembly and mold closing.The first mold plate 304 and the second mold plate 305, once cast, will have their sides containing the special mold cavity 306 for the bearing rings pushed to the outer end of the gantry frame 1, forming a V shape again for demolding. This allows for simultaneous mold closing, casting, and demolding / cleaning.
[0090] In summary, this dual-station alternating casting design eliminates the idle time of traditional equipment waiting for demolding and cooling, achieving uninterrupted casting operation. When one set of molds is being cast, the other set is simultaneously demolded and cooled, ensuring seamless production cycle and meeting the needs of large-scale production of bearing rings.
