[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0040] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example 1

[0041] Please see Figure 1-5 This utility model provides a technical solution:

[0042] like Figure 1 and Figure 2 As shown, the energy-saving fully automatic metal ingot preparation device provided by this utility model includes a sealed furnace body assembly, a molten material turning device, and a resistance furnace heating device 2. The sealed furnace body assembly includes a sealed tank 1 with a vacuum system; the sealed tank 1 is a cylindrical horizontal structure, and its bottom is fixed to a support frame 4; a saddle 5 connected to the support frame 4 is welded to the bottom side wall of the sealed tank 1. The cooperation between the saddle 5 and the support frame 4 achieves stable fixed support for the tank body of the sealed tank 1, ensuring that the tank body has no displacement deviation during equipment operation. The top of the sealed tank 1 is provided with a raw material inlet, and a first sealed furnace cover 6 is provided on the raw material inlet. The first sealed furnace cover 6 is a head-type end cap structure, which can effectively ensure the sealing performance of the inlet.

[0043] The bottom of the sealed tank 1 is equipped with a casting outlet, from which the molten material in the vacuum melting chamber 201 is poured out. The side wall of the sealed tank 1 is provided with a vacuum pipeline connection port and a wiring pre-reservation port. The vacuum pipeline connection port is used to connect to the vacuum system of the equipment to create a vacuum environment inside the sealed tank 1. The wiring pre-reservation port is used to run heating, temperature measurement, and other related wiring. A heating furnace tilting shaft hole is also provided on the side wall of the sealed tank 1. This tilting shaft hole is used to connect the molten material tilting device, providing structural support for the subsequent rotation and tilting of the resistance furnace heating device 2 driven by the molten material tilting device.

[0044] like Figure 3 As shown, the resistance furnace heating device 2 is rotatably installed inside the sealed container 1. The sealed chamber inside the resistance furnace heating device 2 is a vacuum melting chamber 201, and a crucible with a volume of 14.5L is installed inside the vacuum melting chamber 201. The crucible is made of magnesium-aluminum material and serves as the core carrier for melting the metal raw materials. The resistance furnace heating device 2 also includes a heating resistor and a thermocouple installed inside the heating furnace body 203. The heating resistor uses a silicon molybdenum rod heating tube to surround the crucible for heating, with a heating range of 0~1300℃, which can precisely control the temperature to ensure that the metal raw materials are fully melted. The thermocouple collects temperature data in real time during the heating process, providing monitoring and assurance for the stability of the melting process parameters.

[0045] The resistance furnace heating device 2 specifically includes a heating furnace body 203 and a second sealing cover 202. The top opening of the heating furnace body 203 is aligned vertically with the raw material inlet, which facilitates the direct entry of the raw material into the vacuum melting chamber 201 inside the heating furnace body 203 from the inlet. The first sealing cover 6 is equipped with an automatic lifting structure connected to the second sealing cover 202. The opening and closing of the second sealing cover 202 can be controlled synchronously through the automatic lifting structure, further enhancing the sealing effect of the vacuum melting chamber 201.

[0046] like Figure 4 As shown, in order to achieve stable rotation of the resistance furnace heating device 2, resistance furnace supports 16 are provided on the front and rear side walls inside the sealed tank 1. The front and rear sides of the outer shell of the heating furnace body 203 are respectively rotatably hinged to the resistance furnace supports 16 via support shafts 10. The support shafts 10 are installed on the resistance furnace supports 16 via seated bearings 11. After the support shafts 10 pass through the seated bearings 11, they are radially limited by bolts passing through them, which effectively prevents the support shafts 10 from radially shifting during rotation and ensures the stability of the overall installation structure.

[0047] The molten material turning device配套 with the resistance furnace heating device 2 includes a tilting drive mechanism 3 connected to the resistance furnace heating device 2. The tilting drive mechanism 3 drives the resistance furnace heating device 2 to rotate and tilt, so as to control the operation of pouring out the molten material in the crucible. The tilting drive mechanism 3 includes a first servo motor 301, the output shaft of which is flush with the rotating shaft hole of the heating furnace. The output shaft of the first servo motor 301 is connected to the support rotating shaft 10 on one side through a universal coupling 7 passing through the rotating shaft hole of the heating furnace. The central axes of the support rotating shafts 10 on the front and rear sides of the outer shell of the heating furnace body 203 coincide, and the support rotating shafts 10 are arranged at a position below the middle of the heating furnace body 203. This position design can make the heating furnace body 203受力均衡 when rotating, greatly improving the stability of the molten material pouring process. The first servo motor 301 and the reducer are installed on the outer bracket of the circumference of the heating furnace body 203. The torque is transmitted between them by two gears, a small gear and a large gear. Among them, the small gear is connected to the output end of the reducer, and the large gear is installed on the outer shaft head of the rotating shaft of the first servo motor 301. Through the transmission method of gear meshing, the torque output of the first servo motor 301 can be accurately controlled, and finally the accurate control of the automatic turning and casting process of the crucible in the heating furnace body 203 can be realized, ensuring the uniformity and process controllability of the molten material pouring. Embodiment 2

[0048] As Figure 4 Shown, the energy-saving full-automatic metal ingot preparation device of the present utility model further includes a furnace cover opening and closing mechanism, which cooperates with the second sealing cover 202 of the resistance furnace heating device 2 to form a double-sealing protection. The furnace cover opening and closing mechanism includes a first sealing furnace cover 6, a rotating mechanism, and a lifting mechanism. Among them, the lifting mechanism is the core power component for realizing the opening and closing of the first sealing furnace cover 6. Specifically, it includes a lifting cylinder 8 and a horizontal bracket 9. The lifting cylinder 8 is vertically arranged on the sealing tank 1 near the raw material feeding port. One end of the horizontal bracket 9 is connected to the piston rod end of the lifting cylinder 8, and the other end bottom is fixedly connected to the first sealing furnace cover 6. The lifting cylinder 8 drives the horizontal bracket 9 to move up and down, so as to control the opening and closing of the first sealing furnace cover 6. When it is necessary to open the raw material feeding port, the piston rod of the lifting cylinder 8 extends upward,带动 the horizontal bracket 9 to move up synchronously, and then牵引 the first sealing furnace cover 6 to脱离 the raw material feeding port to实现开启; when it is necessary to seal, the piston rod of the lifting cylinder 8 retracts downward, the horizontal bracket 9 moves down随之, and the first sealing furnace cover 6贴合 the raw material feeding port to完成关闭. The whole process实现自动化操作 through cylinder drive, reducing manual intervention.

[0049] To achieve synchronous opening and closing of the first sealed furnace cover 6 and the second sealed cover 202 of the resistance furnace heating device 2, the first sealed furnace cover 6 controls the simultaneous opening and closing of its internal second sealed cover 202 via an automatic lifting structure. The automatic lifting structure includes a third servo motor 14 and a rotating gear 12 mounted on the first sealed furnace cover 6, and a chain 13 connected to the second sealed cover 202. The output shaft of the third servo motor 14 is connected to the rotating shaft of the rotating gear 12. By controlling the forward and reverse rotation of the rotating gear 12 through the third servo motor 14, the lowering height of the chain 13 is controlled, thereby controlling the rising opening and lowering closing of the second sealed cover 202. When the furnace lid is opened, the third servo motor 14 drives the rotating gear 12 to rotate forward. The gear meshes and drives the chain 13 to wind upward, thereby pulling the second sealing cover 202 upward and opening the top opening of the heating furnace body 203. When the furnace lid is closed, the third servo motor 14 drives the rotating gear 12 to rotate in the opposite direction, the chain 13 slowly lowers, and the second sealing cover 202 descends and fits against the top opening of the heating furnace body 203, completing the secondary sealing of the vacuum melting chamber 201. Through the coordinated control of the lifting mechanism and the automatic lifting structure, the first sealing furnace lid 6 and the second sealing cover 202 can be opened and closed synchronously, which not only ensures the degree of automation of the operation, but also further enhances the sealing reliability of the vacuum melting chamber 201 and avoids vacuum leakage problems caused by asynchronous opening and closing of the sealing covers. Example 3

[0050] like Figure 3 and Figure 5 As shown, the energy-saving fully automatic metal ingot preparation device of this utility model has a cylindrical horizontal sealed tank, which includes end caps 101 at both ends and a main tank body 102 in the middle. The end caps 101 and the main tank body 102 are connected by flanges. This connection structure facilitates the assembly of components during the equipment installation and commissioning stage, and also enables quick disassembly and assembly during subsequent maintenance. At the same time, the flange connection and sealing components can effectively ensure the sealing performance of the inner cavity of the tank and avoid leakage in the vacuum environment.

[0051] Both end caps 101 and the main tank 102 in the middle are double-layered shells with cooling water introduced inside. During equipment operation, the cooling water continuously circulates inside the double-layered shell, which can quickly remove the heat transferred from the sealed tank 1 to the shell due to the high temperature of internal melting. This avoids damage to the outer parts of the tank due to high temperature and ensures the safety of operators when contacting the outside of the tank. At the same time, it maintains a stable temperature environment inside the tank, providing suitable external conditions for the vacuum melting process.

[0052] The intermediate main tank 102 has a double-layer hollow jacket structure, with both the inner and outer layers made of stainless steel. Stainless steel is suitable for the high-temperature environment and corrosive gases that may occur during metal smelting, while also ensuring the structural strength of the main tank and preventing shell deformation after long-term use. The end caps 101 at both ends of the sealed tank 1 also have a double-layer structure, including an outer end cap and an inner end cap. The inner and outer end caps work together to form a dual protection of sealing and heat insulation. Together with the double-layer jacket structure of the intermediate main tank 102, they construct a complete integrated sealing and cooling protection system for the sealed tank 1, providing reliable support for the stable operation of the resistance furnace heating device 2 inside the tank and the efficient operation of the vacuum system. Example 4

[0053] like Figure 2 As shown, the energy-saving fully automatic metal ingot preparation device of this utility model is further equipped with a mold rotation device 15 at the bottom that matches the casting outlet. The mold rotation device 15 includes an ingot mold 1501, a turntable 1502, a cooling water tank, a rotary drive device 1503, and a weighing device. Multiple ingot molds 1501 are axially evenly distributed and limited on the circumference of the turntable 1502. Mold positioning points are set on the turntable 1502 and heat insulation cotton is added. The mold material is 310S. A rotary drive device 1503 is provided below the turntable 1502. Its rotation angle and speed are preset and controlled by a second servo motor in conjunction with a detection switch. It can drive the turntable 1502 to rotate steadily according to the casting requirements, so that the ingot molds 1501 are precisely positioned one by one below the casting outlet to receive the molten material, realizing continuous casting operation of multiple molds. A weighing device is installed below the rotary drive device 1503. This device uses a cantilever beam load cell with a range of 0.5-1t and an accuracy of 0.2-0.5. It can detect the weight of the molten material in the ingot mold 1501 in real time, realize the quantitative measurement of the molten material, and ensure the consistency of the weight of each metal ingot.

[0054] This utility model discloses an energy-saving fully automatic metal ingot preparation device, which also includes a vacuum system to provide a stable vacuum environment for the vacuum melting chamber 201 inside the tank. The system comprises a vacuum pump 17, vertical pipes, and horizontal pipes. The lower end of the vertical pipe is sealed to the vacuum pump 17, and the upper end is connected to the horizontal pipe via a baffle valve. The other end of the horizontal pipe is fixedly connected to the vacuum pipe connection port on the side wall of the sealed tank 1, forming a complete vacuum extraction channel. Simultaneously, a venting valve and a pressure sensor are installed on the horizontal pipe. The baffle valve controls the opening and closing of the vacuum pipe; after the vacuum pump 17 starts, opening the baffle valve extracts air from the sealed tank 1. The pressure sensor monitors the vacuum level in the pipe in real time and provides feedback data, with a pressure range of -0.1 MPa to atmospheric pressure, ensuring that the vacuum level inside the tank meets the melting requirements. After melting is completed, opening the venting valve quickly balances the air pressure inside and outside the tank, facilitating subsequent opening of the sealing cover.

[0055] The energy-saving fully automatic metal ingot preparation device of this utility model also includes a loading and unloading transfer device, which consists of a six-axis robot, a base frame, grippers, and a controller; the metal raw material is transported by the robot into the material bin of the feeding component; the metal ingot after casting and cooling is transported by the robot into the transfer cylinder, and then the transfer cylinder is moved onto the feeding and upgrading machine. Example 5

[0056] The method of using this energy-saving fully automatic metal ingot preparation device includes the following steps:

[0057] Step S1: In the initial material feeding stage, a six-axis robot in the hot chamber grabs the metal raw material and accurately pours the material into the feeding port at the top of the equipment according to the preset motion trajectory.

[0058] Step S2: Material conveying process. After the material is poured into the feeding port, the ultra-high vacuum pneumatic slide valve between the feeding port and the crucible is opened, so that the material is stably conveyed along the preset channel to the crucible in the vacuum melting chamber 201 inside the sealed tank 1.

[0059] Step S3: Start the vacuum melting preparation and heating program. First, close the ultra-high vacuum pneumatic slide valve to cut off the connection between the feeding channel and the outside. Then, turn on the vacuum system and use vacuum pump 17 to extract air from the sealed tank 1. The pressure sensor monitors the vacuum level in the tank in real time until the required vacuum level is reached. After the vacuum level is reached, turn on the medium frequency induction heating device to heat the material in the crucible and gradually melt the material.

[0060] Step S4: Molten material casting operation. After the material is completely melted, open the lower casting valve at the bottom of the sealed tank 1, and at the same time start the tilting drive mechanism 3 of the molten material tilting device to drive the crucible to automatically tilt with the heating furnace body 203. After the molten material is tilted by the crucible, it is guided by the chute to flow precisely into the ingot mold 1501 of the sealed tank 1, and then undergoes preliminary cooling in the hot chamber.

[0061] Step S5: Casting quantity control is completed through the interlocking control of the weighing device and the flipping drive mechanism. The rotary drive device 1503 drives the turntable 1502 to rotate, and accurately positions the eight ingot molds 1501, which are evenly distributed on the turntable 1502, one by one below the chute. At the same time, the cantilever beam weighing sensor below the rotary drive device 1503 detects the weight of the mold currently receiving the molten material in real time.

[0062] Step S6: Finished product transfer. After the molten material in the mold has completely cooled and solidified into a metal ingot, the six-axis robot in the hot chamber is restarted to transport it into the transfer cylinder. After the transfer cylinder is full, the robot continues to move the transfer cylinder and places it stably on the hot chamber inlet / outlet elevator. The elevator then transports the transfer cylinder to the subsequent processing or storage stage, completing the entire metal ingot preparation process.

[0063] In summary, the energy-saving fully automatic metal ingot preparation device of this utility model has a simple and ingenious structure. Through the servo motor driving the molten material turning device and the universal coupling transmission structure, the automatic lifting system of the furnace cover opening and closing mechanism, and the precise positioning and weighing module of the mold rotating device, the core processes are integrated into an integrated automatic process, realizing the automated closed-loop control of the entire metal ingot preparation process. It has a high degree of integration and excellent functional module synergy. It can complete the entire process test without additional auxiliary equipment, significantly improving the efficiency of ingot preparation and the stability of test data, while saving space, simplifying the process connection, and effectively reducing labor and production equipment costs.

[0064] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
