Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of casting production, and relates to a pouring device and a pouring production system with the same. Background Art
[0002] Centrifugal casting, an advanced metal forming technology, focuses on injecting liquid metal into a high-speed rotating mold. Using centrifugal force, the molten metal is evenly distributed throughout the mold, forming a casting of the desired shape. This process not only enhances the molten metal's ability to fill the mold but also significantly improves the density and mechanical properties of the casting, reducing common defects such as porosity and slag inclusions in traditional castings. The technology's origins can be traced back to the production of cast pipes. Due to its significant process advantages, such as high yield rates, simplified production processes, and excellent casting quality, centrifugal casting has rapidly gained widespread application in multiple industrial fields, particularly in metallurgy, mining, transportation, irrigation and drainage machinery, aviation, and defense. Centrifugal casting has demonstrated its irreplaceable value in the production of complex shaped parts such as tubular, sleeve-shaped, and ring-shaped parts.
[0003] However, within the framework of existing technologies, there are still some urgent problems to be solved in the pouring system of centrifugal casting. Traditionally, pouring systems mostly use integrally movable tundishes and croissant bags as transfer tools for molten metal raw materials. Although this design meets production needs to a certain extent, when faced with roller production lines of different lengths, since the pouring position of the pouring robot or vehicle is relatively fixed, it is often necessary to extend the robot arm or adjust the position of the vehicle for pouring, which not only increases the complexity of the operation, but also easily leads to inaccurate pouring position, thereby affecting the dimensional accuracy and overall quality of the casting. Especially in industrial production that requires high precision and high consistency, the instability of this pouring method has become a key factor restricting production efficiency and product quality. Utility Model Content
[0004] In view of this, the purpose of the present invention is to provide a casting equipment and a casting production system having the same. By dividing the production system into a smelting area and a pouring area, and effectively isolating them through electric doors, the independence and safety of the two areas are ensured. The smelting area is responsible for heating the metal raw materials to a molten state, while the centrifuge in the pouring area is responsible for evenly distributing the molten metal into the mold, achieving a clear division of labor and efficient collaboration in the production process. By independently setting up the tundish and croissant, the problem of inaccurate pouring caused by the pouring RGV extending itself for pouring is avoided, thereby improving the production quality of the product.
[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

An electric door is provided at the junction of the charging and maintenance area and the smelting area to control the on and off of the two. The smelting area is provided between the casting area and the charging and maintenance area. The charging and maintenance area is used to park the casting RGV.

[0016] Optionally, an RFID reader is also provided on the casting RGV, and an RFID tag is provided on the track. When the casting RGV runs on the track, the RFID reader reads the position information on the RFID tag and transmits the position information to the casting production system.
[0017] The beneficial effect of this utility model lies in: by dividing the production system into a smelting area and a pouring area, effectively isolating them through electric doors, the independence and safety of the two areas are ensured. The smelting area is responsible for heating the metal raw materials to a molten state, while the centrifuge in the pouring area is responsible for evenly distributing the molten metal into the mold, achieving a clear division of labor and efficient collaboration in the production process.

[0026] RGVs, short for Rail Guided Vehicles, are automated transport equipment that travel along fixed tracks. They rely on onboard sensors and laser or magnetic guidance systems to identify and locate the track, allowing them to accurately transfer cargo between stations.
[0027] AGV, short for Automated Guided Vehicle, is a transport vehicle equipped with an automatic guidance device, such as an electromagnetic or optical one, that can travel along a prescribed path and features safety protection and various transfer functions.
[0028] See also Figure 1 , a casting production system, comprises adjacent smelting and pouring areas, physically separated by an electrically operated door 4 to ensure safety and independence during the production process. The smelting area houses one or more smelting furnaces 2, which heat the raw metal to a molten state. The pouring area is equipped with a centrifuge 5, which evenly distributes the molten metal into the mold, resulting in high-quality castings.
[0029] Optionally, the casting production system also includes a charging and maintenance area. The charging and maintenance area is used to park and maintain the casting RGV1 (Robot Guided Vehicle) in a non-working state. An electric door 4 is also provided between the charging and maintenance area and the smelting area to ensure safety during the maintenance process. In order to guide the casting RGV1 to move efficiently between various areas, the casting production system has laid a track 3 that runs through the charging and maintenance area, the smelting area and the casting area. An RFID tag is embedded in the track 3, and the casting RGV1 is equipped with an RFID reader. When the casting RGV1 runs along the track 3, the RFID reader can read the RFID tag information on the track 3 in real time, and transmit the location data to the control center of the casting production system to achieve precise navigation and scheduling.
[0030] Optionally, the smelting area is also equipped with a furnace front operation station 9. This allows operators to monitor the operating status of the entire production line, including the working conditions of the smelting furnace 2, pouring RGV 1, centrifuge 5, and other auxiliary equipment. Based on the production plan and order information, the furnace front operation station 9 can automatically or manually schedule various production equipment to ensure a smooth production process. During the pouring preparation phase, operators must confirm the completion of pouring preparations at the furnace front operation station 9, confirming that all safety doors 8 are locked, the pouring area is clear, and no personnel are present. After confirmation, the furnace front operation station 9 sends instructions to the pouring RGV 1 and smelting furnace 2 and proceeds with the smelting of the metal raw material. During the production process, in the event of an emergency or equipment failure, operators can quickly shut down the system through the furnace front operation station 9 to ensure the safety of equipment and personnel. Furthermore, the furnace front operation station 9 can display fault information to guide operators in troubleshooting or contact maintenance personnel for assistance.
[0031] The casting production system includes multiple casting equipment. Figure 2As shown, the casting equipment includes a casting RGV1, a transfer component and a centrifuge 5. The casting RGV1 can move relative to the centrifuge 5 and the transfer component. The casting RGV1 is used to transport molten metal raw materials. The transfer component is arranged on the side of the centrifuge 5 close to the casting RGV1. The transfer component can move relative to the casting RGV1 and the centrifuge 5. When the casting RGV1 moves to the centrifuge 5, the transfer component is located between the casting RGV1 and the centrifuge 5 to receive the metal raw materials in the casting RGV1 and transfer the metal raw materials to the centrifuge 5.
[0032] Furthermore, the transfer component includes a tundish 10 and a croissant 11, which are movably arranged on one side of the centrifuge 5 close to the pouring RGV1; the croissant 11 is located between the tundish 10 and the centrifuge 5, and its outlet extends toward the centrifuge 5, and the outlet corresponds to the feed port of the centrifuge 5. The metal raw material in the pouring RGV1 flows into the croissant 11 through the tundish 10, and is further transported to the centrifuge 5 through the croissant 11.
[0033] In the casting production system, multiple casting RGVs (1) reciprocate between the smelting area and the casting area, transporting molten metal. Each casting RGV is equipped with a specially designed ladle 13, which is internally equipped with a telescopic mechanism, a lifting mechanism, and a tilting mechanism. The telescopic mechanism allows the ladle 13 to be moved horizontally toward or away from the centrifuge 5 to accommodate different casting positions; the lifting mechanism adjusts the ladle 13's position vertically to ensure accurate casting; and the tilting mechanism flips the ladle 13 upon reaching the casting position, ensuring accurate pouring of the molten iron.
[0034] Specifically, if Figure 2 As shown, the lifting mechanism is a lifting column mounted on the RGV base, capable of adjusting the position of the ladle 13 along the Z-axis. The telescopic mechanism is a telescopic beam connected to the lifting column and extending toward the centrifuge 5. This mechanism can adjust the position of the ladle 13 along the Y-axis, moving it closer to or further away from the tundish 10. The tilting mechanism is a tilting bracket hinged to the side of the telescopic beam near the tundish 10, to which the ladle 13 is attached. The tilting mechanism rotates the ladle 13 about the R-axis, thereby dumping the raw metal from the ladle 13 into the tundish 10.
[0035] During the specific implementation process, the pouring RGV 1 moves in front of the centrifuge 5 via the track 3 and ensures that the ladle 13 is aligned with the tundish 10. In the Y-axis direction, the telescopic beam connected to the lifting column is extended, so that the tilting bracket on the telescopic beam drives the ladle 13 toward the tundish 10. When the ladle 13 approaches the tundish 10 to the appropriate position, the tilting mechanism is activated, and the tilting bracket rotates around the R-axis, driving the ladle 13 to tilt, so that the molten metal raw material in the ladle 13 flows into the tundish 10 through a pouring action. After the metal raw material is completely poured from the ladle 13 into the tundish 10, the tundish 10 begins to automatically move toward the croissant 11. This movement is driven by a servo motor. After the tundish 10 moves to the appropriate position, the tundish 10 can pour the metal raw material therein into the croissant 11. The design of the croissant 11 allows its outlet to closely align with the feed port of the centrifuge 5, ensuring that the metal raw material can flow smoothly into the centrifuge 5. As the metal raw material flows into the centrifuge 5, the centrifuge 5 starts to rotate at high speed, so that the metal raw material is evenly distributed into the mold under the action of centrifugal force, and finally forms the desired casting.
[0036] Optionally, a centrifuge protective cover 12 is provided on the centrifuge 5. A stainless steel accordion cover 15 is provided on the telescopic mechanism. The centrifuge protective cover 12 can prevent the splashing objects generated by the centrifuge 5 when rotating at high speed from injuring people, such as metal fragments, hot molten iron, etc. Through physical isolation, the risk of personal injury caused by improper operation of the centrifuge 5 or equipment failure is significantly reduced. Before pouring, the centrifuge protective cover 12 is closed to ensure that the centrifuge 5 operates in a closed environment. After the pouring is completed, wait until the centrifuge 5 stops rotating completely and the temperature drops, and then open the protective cover to proceed to the next step. The stainless steel accordion cover 15 can prevent the splashing of molten iron, heat radiation, etc. from damaging other equipment or lines on the casting RGV1, thereby reducing the damage to the casting RGV1 caused by external environmental factors (such as high temperature, humidity, corrosion, etc.). The stainless steel accordion cover 15 can significantly improve the durability and reliability of the equipment and reduce the failure of the casting RGV1 caused by external environmental factors. When designing the casting RGV1, the stainless steel accordion cover 15 is installed as part of the telescopic mechanism. During the pouring process, the stainless steel accordion cover 15 expands or contracts with the movement of the telescopic mechanism and always covers the top of the telescopic mechanism.
[0037] In one possible embodiment, the pouring RGV 1 is also equipped with a weighing display 14. During the pouring process, the operator can use the weighing display 14 to check the weight of the molten iron ladle 13 at any time, ensuring the accuracy of the molten iron amount and avoiding product quality issues caused by insufficient or excessive molten iron. The data on the weighing display 14 can be compared in real time with the weighing data of the tundish 10 in the centrifuge 5, enabling precise control of the pouring process. If the weighing data on the pouring RGV 1 differs significantly from the weighing data of the tundish 10, the weighing display 14 can serve as an alarm to promptly notify the operator to check for possible fault points. The provision of the weighing display 14 enables the pouring production system to monitor and display the molten iron weight in real time, ensuring the accurate amount of molten iron for each pour, thereby improving product quality and consistency. The provision of the weighing display 14 allows the operator to promptly detect and address any abnormal molten iron weight, avoiding safety hazards such as overflow or spattering caused by excessive molten iron. Automated and precise pouring control reduces the need for human intervention, speeds up the production process, and improves overall production efficiency.
[0038] Furthermore, an electrical control box 16 is installed on the RGV1. This box provides a stable and reliable power supply to the various motors, sensors, displays, and other components on the RGV1. It also has overcurrent and overvoltage protection functions to ensure the safe and stable operation of the electrical system.
[0039] To further enhance pouring accuracy and safety, the pouring RGV1 is equipped with a lidar sensor 17 and an infrared ranging sensor 18. The lidar sensor 17 detects in real time whether there are any obstructions in the pouring RGV1's path. If an obstacle is detected, emergency braking is triggered to prevent a collision. The infrared ranging sensor 18 monitors the distance between the pouring RGV1 and the tundish 10, ensuring precise control of the pouring process.
[0040] In the specific workflow, when the pouring production system receives the start signal, two pouring RGVs (1) each head to the smelting area to receive molten metal. They then move along track 3 to the pouring area and, following a predetermined sequence and path, accurately pour the molten iron into the centrifuge 5 via the tundish 10 and croissant 11. During the pouring process, the molten iron first enters the tundish 10 and is then transported to the feed port of the centrifuge 5 via the croissant 11. After completing a pouring cycle, the other pouring RGV (1) continues the same operation to ensure the continuity and stability of the pouring process. Once both pouring RGVs (1) complete their pouring tasks, they automatically return to their initial positions or to the recharging and maintenance area, awaiting the next task.
[0041] In one possible embodiment, a remelting trough 6 is further provided in the pouring area of the pouring production system. The remelting trough 6 is used to collect and process raw metal that fails to enter the centrifuge 5, or to collect excess raw metal generated during the pouring process. This raw metal can be remelted and reused, thereby reducing waste and improving production efficiency.
[0042] In one possible embodiment, the casting production system is further provided with a mold transfer AGV 7, which is used to transfer molds (casting molds) within the casting area or between other areas. After casting is completed, the mold transfer AGV 7 can transfer the mold containing the finished product to the next production stage (such as cooling, cleaning, inspection, etc.), or return the empty mold to the casting area for subsequent use.
[0043] In one possible implementation, the pouring production system integrates a dynamic metal raw material weight compensation algorithm. If the weight of the first pour (outer layer of molten iron) is insufficient, the pouring production system automatically adjusts the second pour (inner layer of molten iron) according to preset compensation rules to ensure a consistent total product weight. This function is achieved by acquiring real-time weighing data from the pouring RGV 1 and the tundish 10 of the centrifuge 5, combined with the product weight requirements specified in the production order.
[0044] In one possible embodiment, the pouring production system has a pre-set program. This program controls the pouring sequence and time interval between the two pouring RGVs 1. For example, the first pouring RGV 1 pours the outer layer of molten iron. After a certain period of time, the second pouring RGV 1 pours the inner layer of molten iron. The amount of molten iron poured each time is monitored in real time by a load cell and compared with the preset pouring amount to ensure the accuracy of the pouring amount.
[0045] In one possible implementation, the casting production system includes a status monitoring module that can collect and record key parameters of each device in real time, such as the power and position of the pouring RGV 1, the weight of the molten iron, the status and speed of the centrifuge 5, and the position of the tundish 10. This data is transmitted to the casting production system via the workshop's wireless or wired network.
[0046] In one possible implementation, the pouring production system installs cameras at key locations on the production line and connects them to a server for real-time monitoring. The cameras have night vision and motion detection capabilities, ensuring 24 / 7 monitoring of the production line's operations.
[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
