Description

Technical Field

[0001] The present invention relates to the technical field of intelligent casting islands, and more specifically, to an automatic switching device for multi-station casting of agricultural machinery parts in an intelligent casting island. Background Art

[0002] An intelligent casting island is a highly integrated and intelligent casting production unit. By integrating industrial Internet of Things, robot automation, digital twin, and artificial intelligence technologies, processes such as melting, casting, cooling, and inspection in traditional casting processes are integrated into a modular collaborative system. Its core is data-driven flexible manufacturing capabilities, which can dynamically adjust process parameters, monitor equipment status in real time, and achieve seamless switching between multiple stations and optimal allocation of resources, significantly improving the consistency of casting quality, production efficiency, and energy utilization rate. It is the core solution to promote the transformation of the casting industry towards unmanned, green, and customized production.

[0003] Multi-station casting of agricultural machinery parts refers to the metal liquid forming process of agricultural machinery parts (such as gearboxes, plowshares, harvester blades, etc.) completed through the coordinated cooperation of multiple functional stations (such as melting, casting, cooling, demolding, etc.) within the same casting production unit.

[0004] Existing multi-station casting devices for agricultural machinery parts have two significant drawbacks in the automatic switching structure: Firstly, in the mechanical transmission system that uses a motor to drive a rotating platform, components such as gears and bearings are prone to wear and generate gaps during long-term operation, resulting in positioning deviations between the rotating seat and the mounting seat, affecting the accuracy of station alignment and the accuracy of casting positions. Although servo control or cam indexers improve accuracy, the servo system has cumulative errors and requires regular origin resetting, increasing the complexity of maintenance. Secondly, the devices generally lack an effective circulating cooling structure (such as the base and mold not being equipped with cooling water chambers). Prolonged continuous casting is likely to cause components to overheat, accelerating material aging and posing safety risks such as misoperations or burns, restricting the reliability of the equipment and production safety. Summary of the Invention

[0005] The present invention provides an automatic switching device for multi-station casting of agricultural machinery parts in an intelligent casting island. Through improvements to the cooling component and the rotating component, when the rotating component drives the mold component to rotate, it can stir the liquid inside the cooling component to circulate and flow, and self-cool the mold component after casting. Moreover, structural designs such as rolling elements and elastic elements are used to reduce the gaps caused by wear of mechanical components, making the positioning of the mold component more accurate during station switching and reducing the influence of cumulative errors in the servo system, thereby solving the problems raised in the above background art, namely: In the existing device, mechanical components driven by a motor to rotate the platform are prone to wear and cause positioning deviations, the servo system needs to be reset to the origin regularly, increasing the complexity of maintenance, and the lack of an effective circulating cooling structure leads to overheating of components.

[0006] To achieve the above object, the automatic switching device for multi-station casting of agricultural machinery parts includes legs, and a cooling component is fixedly connected between the tops of the plurality of legs. A rotating component is provided between the inside and the top of the cooling component. A plurality of mold components are provided inside the rotating component. A pouring machine is provided between one outer wall of the rotating component and the cooling component; The pouring head of the pouring machine is located above the rotating component. The pouring machine is used for pouring into the inside of the mold component. The rotating component is used for switching the working positions of the pouring operations of the plurality of mold components; During the rotation of the rotating component, the mold component ascends and descends by itself inside the cooling component. The cooling component is used for cooling the poured mold component. While driving the mold component to rotate, the rotating component also stirs the liquid inside the cooling component to circulate.

[0007] In the above technical solution, the cooling component includes a condensation box, and the condensation box is fixedly connected between the tops of the plurality of legs. A circulation component is provided between the outer walls of the condensation box.

[0008] On this basis, two annular grooves are provided inside the condensation box. Coolant is provided inside the groove of the condensation box close to the outer wall. A rotating component is provided between the inside of the groove of the condensation box close to the inner wall and the top.

[0009] The circulation component includes water pipes. The two water pipes are respectively fixed at both ends of the outer wall of the condensation box. A one-way valve is provided between the two water pipes.

[0010] Among them, the one-way valve includes a valve housing. The valve housing serves as the main frame, and a fluid channel and an installation cavity are provided inside. A piston is provided inside the valve housing. One end of the piston is fixedly connected with a push rod. The other end of the push rod is fixedly connected with a pressing plate. A spring piece is provided between the pressing plate and the fluid channel of the valve housing.

[0011] In another technical solution, the rotating component includes a motor. The motor is fixedly connected to the bottom of the condensation box. The output shaft of the motor is fixedly connected with a switching plate. The switching plate is movably connected to the top of the condensation box. Rolling parts are provided inside the groove of the condensation box close to the inner wall.

[0012] The rolling parts include ball bearings. The ball bearings are movably placed inside the groove of the condensation box close to the outer wall. A rotating rod is fixedly connected to the outer wall of the ball bearings. The rotating rod is movably connected inside the condensation box.

[0013] A plurality of grooves are provided inside the switching plate close to the outer wall. The plurality of grooves of the switching plate are all provided with mold components.

[0014] On this basis, the mold assembly includes a mold base. The outer wall of the mold base is designed with an arc shape near the bottom. The mold base is movably clamped inside the groove of the switching plate, and a lifting member is provided between the mold base and the inner wall of the groove of the switching plate.

[0015] The lifting member includes sliders. The three sliders are respectively fixedly connected to the three inner walls of the groove of the switching plate. The sliders are slidably connected inside the sliding grooves on the outer wall of the mold base, and an elastic member is provided between the sliders and the mold base.

[0016] In this technical solution, through the integrated design of the cooling component and the rotating component and the improvement of the elastic lifting structure of the mold assembly, the device has both high-efficiency cooling performance and high-precision station switching ability. Specifically, because: by setting a double-layer annular groove inside the condensation box, the inner layer groove is used to install the rotating component, and the outer layer groove accommodates the coolant. And when the rotating component drives the mold assembly to rotate, the rotation of the mold assembly inside the condensation box can stir the coolant to circulate, and natural convection can be realized without additional power, so as to continuously cool the poured mold assembly, solving the problem of overheating of components caused by the lack of a circulating cooling structure in the traditional device; by setting a lifting structure composed of sliders and elastic members between the switching plate and the mold base, using the pre-tightening force of the elastic member to compensate for the gap generated by wear during the mechanical transmission process, and cooperating with the rolling members to reduce the rotational friction, the mold assembly can maintain the positioning accuracy through elastic self-adaptation during the station switching, avoiding the problems of gap accumulation in the traditional gear bearing transmission and cumulative error of the servo system. At the same time, there is no need for regular origin reset, reducing the maintenance complexity.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. In an automatic switching device for multi-station casting of agricultural machinery parts in an intelligent casting island, by setting a double-layer annular groove inside the condensation box, the outer layer groove accommodates the coolant. When the rotating component drives the mold assembly to rotate to switch the casting station, the mold assembly synchronously stirs the coolant to circulate during the switching process, forming a natural convection cooling system without additional power, continuously cooling the poured mold assembly, avoiding overheating of the base and the mold caused by long-term casting, effectively delaying the aging of the material, eliminating safety risks such as scalding, and significantly improving the reliability of the equipment in a high-temperature environment.

[0018] 2. In an automatic switching device for multi-station casting of agricultural machinery parts in an intelligent casting island, through the cooperative design of the arc-shaped mold frame of the mold assembly and the end of the condensation box, the automatic seamless switching between the casting and cooling processes is achieved: when the mold assembly rotates with the rotating assembly to the lower part of the casting machine, the arc-shaped structure at the bottom of the mold frame contacts the end of the condensation box and is automatically pushed upward by the limiting action of the condensation box, so that the mold is accurately aligned with the casting head, and the station switching and casting preparation can be completed without an additional driving mechanism; after casting, the mold assembly continues to rotate with the rotating assembly, disengages from the end limit of the condensation box, and the mold frame descends into the coolant inside the condensation box by relying on its own gravity and the restoring force of the elastic member, realizing the automatic immersion cooling of the mold after casting. This design eliminates the complex lifting driving components in the traditional device, and uses the mechanical structure linkage to complete the lifting action of the mold, which not only ensures the accurate docking of the casting station, but also realizes efficient cooling through the direct contact of the coolant, avoids manual intervention and additional energy consumption, solves the problem of overheating of components caused by the lack of an effective cooling structure in the existing device, and improves the smoothness and automation degree of multi-station switching at the same time.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Currently, for the problems that the mechanical components of the motor-driven rotating platform in the existing device are prone to wear and cause positioning deviation, the servo system needs to be reset to the origin regularly, increasing the maintenance complexity, and the lack of an effective circulating cooling structure leads to overheating, the present invention provides an automatic switching device for multi-station casting of agricultural machinery parts in an intelligent casting island. Refer to Figures 1 - 10 As shown in the figure, it includes legs 1. A cooling component 2 is fixedly connected between the tops of multiple legs 1. A rotating component 12 is provided between the inside and the top of the cooling component 2. Multiple mold components 13 are provided inside the rotating component 12. A pouring machine 11 is provided between the rotating component 12 and one side outer wall of the cooling component 2. The pouring head of the pouring machine 11 is located above the rotating component 12. The pouring machine 11 is used for pouring into the inside of the mold component 13. The rotating component 12 is used for switching the working positions of the pouring operations of multiple mold components 13. The mold component 13 self-ascends and descends inside the cooling component 2 during the rotation of the rotating component 12. The cooling component 2 is used for cooling the poured mold component 13. While driving the mold component 13 to rotate, the rotating component 12 also stirs the liquid inside the cooling component 2 to circulate.

[0023] During implementation, refer to Figure 7 As shown in the figure, the cooling component 2 includes a condensation box 20. The condensation box 20 is fixedly connected between the tops of multiple legs 1. A circulation component 21 is provided between the outer walls of the condensation box 20. Two annular grooves are provided inside the condensation box 20. Coolant is provided inside the groove of the condensation box 20 close to the outer wall. A rotating component 12 is provided between the inside of the groove of the condensation box 20 close to the inner wall and the top.

[0024] Refer to Figure 8 As shown in the figure, the circulation component 21 includes a water pipe 210. Two water pipes 210 are respectively fixed at both ends of the outer wall of the condensation box 20. A check valve 211 is provided between the two water pipes 210.

[0025] In the automatic switching device for multi-station casting of agricultural machinery parts in this intelligent casting island, the cooling component 2 plays a crucial cooling role. First of all, the tops of multiple legs 1 are fixedly connected to the condensation box 20, forming the basic framework of the entire cooling structure. There are two annular grooves inside the condensation box 20. The groove near the outer wall is for placing the coolant, and the groove near the inner wall is for placing the rotating component 12, so that when the rotating component 12 drives the mold component 13 to rotate, it can be associated with the space where the coolant is located. Two water pipes 210 in the circulation component 21 are respectively fixed at both ends of the outer wall of the condensation box 20, and a one-way valve 211 is arranged between them. During operation, when the rotating component 12 drives the mold component 13 to rotate, the mold component 13 stirs the coolant, causing the coolant to flow in the outer groove of the condensation box 20. During the flow of the coolant, it will circulate through the water pipe 210, and the one-way valve 211 plays a role in controlling the flow direction of the coolant, ensuring that the coolant flows stably in the predetermined direction, avoiding abnormal situations such as backflow, thus forming a complete and stable circulating flow system, realizing continuous and efficient cooling of the mold component 13 after casting, so as to ensure that the entire device can effectively avoid overheating during operation, improve the reliability of the equipment operation and the stability of each station operation.

[0026] Among them, referring to Figure 9 As shown, the one-way valve 211 includes a valve housing 2110. The valve housing 2110 serves as the main framework, with a fluid passage and an installation cavity inside. There is a piston 2111 inside the valve housing 2110. One end of the piston 2111 is fixedly connected to a push rod 2114, and the other end of the push rod 2114 is fixedly connected to a pressure plate 2113. There is a spring piece 2112 between the pressure plate 2113 and the fluid passage of the valve housing 2110.

[0027] When the coolant circulates, if the coolant flows through the one-way valve 211 along the predetermined forward flow direction, the fluid pressure generated will push the piston 2111 to move inside the valve housing 2110. The piston 2111 drives the pressure plate 2113 to squeeze the spring piece 2112 through the push rod 2114, causing the spring piece 2112 to deform, so as to make way for the fluid passage, and the coolant can pass through the one-way valve 211 smoothly, realizing normal forward flow.

[0028] When the coolant shows a reverse flow trend, under the action of the elastic restoring force of the spring piece 2112 itself, the pressure plate 2113 will be pushed back to the initial position, and then the push rod 2114 is pushed to reset the piston 2111, blocking the fluid passage, thus preventing the reverse flow of the coolant, ensuring that the coolant can only flow stably between the water pipes 210 of the circulation component 21 in the set direction, maintaining the normal operation order of the entire cooling circulation system, and ensuring the continuous realization of the effective cooling function of the mold component 13 after casting.

[0029] In addition, refer to Figure 5 As shown, the rotating assembly 12 includes a motor 120, the motor 120 is fixedly connected to the bottom of the condensation box 20, the output shaft of the motor 120 is fixedly connected to a switching plate 122, the switching plate 122 is movably connected to the top of the condensation box 20, and rolling members 121 are arranged inside the groove near the inner wall of the condensation box 20.

[0030] Refer to Figure 6 As shown, the rolling member 121 includes a ball 1210, the ball 1210 is movably placed inside the groove near the outer wall of the condensation box 20, and a rotating rod 1211 is fixedly connected to the outer wall of the ball 1210, and the rotating rod 1211 is movably connected inside the condensation box 20.

[0031] Among them, the motor 120 is used as the power source and is fixedly connected to the bottom of the condensation box 20, and its output shaft is fixedly connected to the switching plate 122. When the motor 120 starts to operate, it will drive the output shaft to rotate, thereby driving the switching plate 122 to rotate movably on the top of the condensation box 20; and rolling members 121 are arranged inside the groove near the inner wall of the condensation box 20, and the balls 1210 in the rolling members 121 are movably placed in the groove near the outer wall of the condensation box 20, and the rotating rod 1211 is fixedly connected to its outer wall and the rotating rod 1211 is also movably connected inside the condensation box 20; during the rotation of the switching plate 122, relying on the rolling structure formed by the balls 1210 and the rotating rods 1211, the rotation action can be carried out in the way of rolling friction, reducing the large friction force and mechanical wear that may be generated by the traditional transmission method; the balls 1210 can roll flexibly in the groove, and the rotating rods 1211 play a role in auxiliary support and connection to ensure that the entire rotation process is smooth and stable. In this way, not only can the function of switching the working positions of multiple die assemblies 13 be accurately realized, but also problems such as easy wear of mechanical parts and positioning deviation caused by long-term operation can be effectively avoided, ensuring the reliable operation of the device and the high precision of the working position switching.

[0032] In addition, refer to Figure 2 As shown, a plurality of grooves are provided near the outer wall inside the switching plate 122, and die assemblies 13 are arranged in each of the plurality of grooves of the switching plate 122.

[0033] Refer to Figure 10 As shown, the die assembly 13 includes a die carrier 130, the outer wall of the die carrier 130 is arc-shaped near the bottom, the die carrier 130 is movably clamped inside the groove of the switching plate 122, and a lifting member 131 is arranged between the inner wall of the groove of the die carrier 130 and the switching plate 122.

[0034] Therefore, the multiple grooves provided inside the switching board 122 near the outer wall play an important role in carrying the mold assembly 13, and the mold assembly 13 is placed in each groove; the outer wall of the mold base 130 in the mold assembly 13 is designed to be arc-shaped near the bottom. This special arc-shaped structure enables the mold base 130 to be movably clamped inside the groove of the switching board 122, thus achieving a relatively stable connection while having a certain amount of movement space. A lifting member 131 is provided between the inner wall of the groove of the mold base 130 and the switching board 122. When the entire device operates, as the rotating assembly 12 drives the switching board 122 to rotate, during the operation of some specific workstations, relying on the cooperation between the arc-shaped structure of the mold base 130 and the external structure (such as the end of the condensation box 20, etc.), the mold base 130 will be subjected to corresponding external forces; at this time, the lifting member 131 can flexibly change the height position of the mold base 130 relative to the groove of the switching board 122 based on the external force situation and its own structural characteristics, realizing the self-lifting action of the mold assembly 13; for example, at the pouring workstation, the mold base 130 is jacked up by the lifting member 131 under the influence of external limits and other factors, and is accurately aligned with the pouring head to complete pouring; after pouring, it can descend relying on its own gravity and the reset action of the lifting member 131 and immerse in the coolant to achieve cooling. Through such a structural cooperation, the automatic and seamless connection of the mold assembly 13 between different processes such as pouring and cooling is realized, ensuring the smooth progress of the operation of each workstation of the entire device and the effective realization of its functions.

[0035] Among them, referring to Figure 10 As shown, the lifting member 131 includes sliders 1310. The three sliders 1310 are respectively fixedly connected to the three inner walls of the groove of the switching board 122. The sliders 1310 are slidably connected inside the chute on the outer wall of the mold base 130. An elastic member 1311 is provided between the sliders 1310 and the mold base 130.

[0036] Specifically, the three sliders 1310 in the lifting member 131 are respectively fixedly connected to the three inner walls of the groove of the switching board 122. They form a sliding connection relationship with the chute on the outer wall of the mold base 130, enabling the mold base 130 to slide up and down relative to the sliders 1310; and the elastic member 1311 provided between the sliders 1310 and the mold base 130 is the key factor for realizing the lifting function. When the device runs to a specific station, such as the pouring station, the mold base 130 is subjected to an external force due to the interaction between its arc-shaped structure and the external structure, and will slide upward along the slider 1310. At this time, the elastic member 1311 is compressed and stores elastic potential energy. With this process, the mold base 130 is jacked up relative to the groove of the switching plate 122, so that the mold assembly 13 can accurately align with the pouring head to complete the pouring operation; when the corresponding operation is completed, the external force disappears, and under the action of the elastic restoring force of the elastic member 1311 itself, the elastic member 1311 releases the stored potential energy, pushes the mold base 130 to slide downward along the slider 1310 to reset, and at the same time combines with the gravity of the mold base 130 itself to make it descend to a suitable position, such as being immersed in the coolant to achieve cooling; through the sliding cooperation between the slider 1310 and the chute and the elastic action of the elastic member 1311, the flexible and automatic lifting of the mold assembly 13 under different station requirements is realized, ensuring the smoothness and automation of the connection of each process of the entire device.

[0037] Working principle: First, after the device is started, the motor 120, as a power source, drives the switching plate 122 to rotate, driving the mold assembly 13 installed in the groove of the switching plate 122 to rotate along a preset trajectory, passing through the pouring station and the cooling area in turn; the rotation of the switching plate 122 is realized by means of the rolling members 121 (ball 1210 and rotating rod 1211) in the inner groove of the inner wall of the condensation box 20. When the ball 1210 rolls in the groove, through the supporting action of the rotating rod 1211, the traditional sliding friction is converted into low-resistance rolling friction, significantly reducing mechanical loss and ensuring the smooth rotation and accurate positioning of the switching plate 122; When the mold assembly 13 rotates with the switching plate 122 to the lower part of the pouring machine 11, the arc-shaped structure at the bottom of the mold base 130 contacts the limit structure at the end of the condensation box 20, and is pushed by the external force to slide upward along the slider 1310 on the inner wall of the groove of the switching plate 122, compressing the elastic member 1311 between the slider 1310 and the mold base 130 and rising, so that the mold gate is accurately aligned with the pouring head of the pouring machine 11 to complete the pouring preparation; after the molten metal is injected into the mold, the switching plate 122 continues to rotate, the mold assembly 13 is separated from the limit of the condensation box 20, and the elastic member 1311 pushes the mold base 130 to descend along the slider 1310 under the action of the restoring force. At the same time, the gravity of the mold base 130 itself assists it to be immersed in the coolant in the outer groove of the condensation box 20 to realize the automatic cooling of the mold after pouring; During the rotation of the mold assembly 13 with the switching plate 122, its outer shape structure synchronously agitates the coolant in the outer grooves of the condensation box 20 to form a flow driving force; the coolant enters the circulation assembly 21 through the water pipe 210. When flowing in a predetermined direction, the fluid pressure pushes the piston 2111 in the one-way valve 211, drives the pressing plate 2113 to compress the spring piece 2112 through the push rod 2114, and opens the fluid passage to enable the smooth circulation of the coolant; if there is a reverse flow tendency, the elastic restoring force of the spring piece 2112 pushes the piston 2111 to block the passage, ensuring that the coolant only flows in a single direction, forming a stable convective cooling system and continuously removing the heat of the mold; In the above process, the low-friction characteristic of the rolling member 121 and the clearance compensation function of the elastic member 1311 cooperate with each other: the former reduces the mechanical wear during the rotation of the switching plate 122, and the latter automatically compensates for the possible fine clearances generated during the transmission process through the elastic pre-tightening force, enabling the mold assembly 13 to maintain high-precision positioning through the self-adaptation of the mechanical structure without relying on the servo system to frequently reset to the origin during the station switching; ultimately, through the integrated design of "rotary drive - station switching - automatic lifting - fluid circulation - elastic positioning", the device realizes the seamless automation connection of multi-station pouring and cooling, and systematically solves the problems of positioning deviation, overheating loss and complex maintenance of the existing device.
