Description

Technical Field

[0001] This utility model relates to the field of copper craft production and processing technology, and more specifically, to a medium-frequency furnace with automatic loading and unloading. Background Technology

[0002] Copper handicrafts are items with artistic and aesthetic value, made primarily of copper and processed through various techniques. In the modern production process of copper handicrafts, copper blanks are placed in an induction furnace to melt them. The molten copper is then poured into a prepared mold to obtain the rough copper handicraft blank.

[0003] In existing medium-frequency furnaces, the inner liner of a traditional medium-frequency furnace is fixed to the furnace body. The entire furnace needs to be tilted by a machine to allow the molten copper inside to flow out. This design not only makes it easy for the molten copper inside to spill when tilting, but also, because the furnace body is fixed, once the copper block is melted into molten copper, it can only be poured out at a fixed location, which restricts operation and results in low production efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide an intermediate frequency furnace with automatic loading and unloading.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0007] The technical solution described above in this application example has at least the following technical effects: This medium-frequency furnace features a detachable inner liner within the outer shell. When the copper billet is melted, the inner liner is gripped by a clamping mechanism and carried out of the outer shell. Then, a moving mechanism transports the inner liner to the casting location, improving processing flexibility. Simultaneously, the movement of the inner liner via the clamping and moving mechanisms eliminates the need for manual operation, preventing workers from being burned and ensuring their safety.

[0008] In some embodiments, the automatically loading and unloading medium-frequency furnace further includes an induction heating element disposed between the outer shell and the inner liner, and located on the inner sidewall of the outer shell, for heating the copper blank.

[0010] In some embodiments, there is a gap between the magnetic coil and the inner liner.

[0011] In some embodiments, a plurality of the hooks are arranged in a ring at equal intervals on the top of the inner liner.

[0012] In some embodiments, the outer casing has a bottom end formed within the outer casing for securing the inner liner.

[0013] In some embodiments, the inner liner further includes a positioning hole disposed at the bottom end of the inner liner for cooperating with the positioning pin to fix the inner liner.

[0014] In some embodiments, the mobility mechanism includes: A support frame is positioned above the inner liner; A horizontal conveying assembly is mounted on the support frame, and its power output end is connected to the clamping mechanism for driving several clamping mechanisms to move horizontally.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1 and Figure 2 This utility model provides an automatic loading and unloading medium-frequency furnace, comprising: an outer shell 10; an inner liner 20, detachably disposed within the outer shell 10 for holding copper billets; a plurality of hanging ears 21 on the top of the inner liner 20; a moving mechanism 30 disposed above the inner liner 20 for moving the inner liner 20; and a plurality of clamping mechanisms 40 disposed between the moving mechanism 30 and the hanging ears 21, and connected to the output end of the moving mechanism 30 for clamping the inner liner 20. The plurality of clamping mechanisms 40 are arranged in a one-to-one correspondence with the plurality of hanging ears 21.

[0020] Understandably, the inner liner 20 is a container for holding the copper billet. Since the copper billet needs to be heated to melt it, the inner liner 20 uses a material with a melting point higher than the copper billet. For example, it could be a graphite inner liner 20, or a silicon carbide refractory inner liner 20, but it is not limited to these. The inner liner 20 can be removed from either the outer shell 10 or from within the inner liner 20, so there can be relative movement between the inner liner 20 and the outer shell 10. For example, the inner liner 20 and the outer shell 10 can be clearance-fitted and not in contact, with the inner liner 20 stationary inside the outer shell 10. Alternatively, the outer shell 10 and the inner liner 20 can be detachably connected by threads, but it is not limited to these. The moving mechanism 30 is a component that linearly transports the inner liner 20 in the horizontal direction. For example, it could be a sliding moving mechanism 30, or a rolling moving mechanism 30, but it is not limited to these. The clamping mechanism 40 is a component that fixes the inner liner 20 to the moving mechanism 30. For example, it could be a finger-type clamping mechanism 40, or a chuck-type clamping mechanism 40, but it is not limited to these.

[0021] As can be seen from the above, this medium-frequency furnace detachably sets the inner liner 20 in the outer shell 10. When the copper billet is melted, the inner liner 20 is clamped by the clamping mechanism 40 and taken out of the outer shell 10. Then, the inner liner 20 is transported to the casting location by the moving mechanism 30, which improves the processing flexibility. At the same time, the inner liner 20 is moved by the clamping mechanism 40 and the moving mechanism 30 without manual operation, avoiding workers being burned and ensuring the safety of workers' lives.

[0022] Optionally, in some embodiments, please refer to Figure 2 The medium-frequency furnace with automatic loading and unloading also includes an induction heating element 50 disposed between the outer shell 10 and the inner liner 20 and located on the inner side wall of the outer shell 10 for heating the copper blank.

[0023] Understandably, the induction heating element 50 is a component that heats and melts the copper blank without contacting it. For example, it can be an electromagnetic heating coil or a multi-turn conductive ring, but it is not limited to these.

[0024] With this configuration, the alternating magnetic field generated by the induction heating element 50 directly acts on the copper blank, causing the copper blank to heat up under the influence of the magnetic field, thereby melting the copper blank, reducing heat transfer, lowering energy consumption, and improving heating efficiency.

[0025] Optionally, in some embodiments, please refer to Figure 4 The induction heating element 50 is a magnetic coil 51 spirally wound around the inner wall of the outer shell 10. There is a gap between the magnetic coil 51 and the inner liner 20.

[0026] Understandably, the magnetic coil 51 is a component that is spirally wound around the inner wall of the outer casing 10 to generate an alternating magnetic field that heats the copper blank itself. For example, it can be a set of long coils spirally wound around the inner wall of the outer casing 10, or it can be multiple sets of magnetic coils 51 spaced apart on the inner wall of the outer casing 10, etc., but it is not limited to these. Since the first arrangement can heat the copper blank more evenly, the first arrangement is preferred. The magnetic coil 51 and the inner liner 20 cannot be in direct contact. For example, the magnetic coil 51 and the inner liner 20 can be spaced apart, or the magnetic coil 51 can be wrapped with a layer of outer casing 10, etc., to separate the magnetic coil 51 and the inner liner 20, but it is not limited to these.

[0027] This arrangement, which separates the magnetic coil 51 from the inner liner 20, prevents the magnetic coil 51 from coming into contact with the high-temperature inner liner 20, thus preventing the insulation layer on the surface of the magnetic coil 51 from aging and falling off, and reducing the lifespan of the equipment.

[0028] Optionally, in some embodiments, please refer to Figure 1 Several loops 21 are arranged in a ring at equal intervals on the top of the inner liner 20.

[0029] Understandably, the hook 21 is a convenient clamping mechanism fixed on the inner liner 20 to lift the handle of the inner liner 20. For example, it can be integrally formed with the inner liner 20, or it can be fixed to the top of the inner liner 20 by welding, etc., but it is not limited to these.

[0030] Optionally, in some embodiments, please refer to Figure 2 and Figure 3 The outer shell 10 has a bottom end formed inside the outer shell 10 for fixing the inner liner 20. The inner liner 20 also includes a positioning hole 22 provided at the bottom end of the inner liner 20 for cooperating with the positioning pin 11 to fix the inner liner 20.

[0031] Understandably, the positioning pin 11 and positioning hole 22 are used to position the inner liner 20 and prevent it from shaking. For example, there can be one positioning pin 11 and one positioning hole 22. The positioning pin 11 is installed in the center inside the outer shell 10, and the positioning hole 22 is installed in the center of the bottom of the inner liner 20. Alternatively, there can be multiple positioning pins 11 and multiple positioning holes 22, which are installed in a ring in the center inside the inner shell, with each positioning hole 22 corresponding to a different positioning pin 11 installed at the bottom of the inner shell.

[0032] This configuration, through the cooperation of the positioning pin 11 and the positioning hole 22, keeps the inner liner 20 stable inside the outer shell 10, preventing the inner liner 20 from shaking and touching the magnetic coil 51, which would cause the insulation layer of the magnetic coil 51 to age and fall off due to high temperature, thus reducing the product's service life.

[0033] Optionally, in some embodiments, referring to Figure 2, the moving mechanism 30 includes: a support frame 31 disposed above the inner liner 20; and a horizontal conveying assembly 32 disposed on the support frame 31 and connected to the lifting assembly 41, for driving several clamping mechanisms 40 to move left and right.

[0034] Understandably, the horizontal conveying assembly 32 is a component used to transport the inner liner 20. For example, it can be an electrically driven horizontal conveying assembly 32 or a hydraulically driven horizontal conveying assembly 32, but it is not limited to these.

[0035] Optionally, in some embodiments, please refer to Figure 1 The clamping mechanism 40 includes: a lifting assembly 41, which is disposed between the moving mechanism 30 and the hanging ears 21 and connected to the output end of the horizontal conveying assembly 32. A plurality of grippers 42 are disposed one-to-one above the plurality of hanging ears 21 and connected to the output end of the lifting assembly 41 for clamping the hanging ears 21. The lifting assembly 41 drives the grippers 42 to perform lifting and lowering movements.

[0036] Understandably, the lifting assembly 41 is the component that drives the gripper 42 to descend and grasp the inner liner 20. For example, it can be a pneumatically driven lifting assembly 41 or an electrically driven lifting assembly 41, but it is not limited to these. The gripper 42 is the component that holds the inner liner 20 in place by gripping the hanging ear 21. For example, it can be a three-finger gripper 42 or a multi-finger gripper 42, but it is not limited to these.

[0037] With this configuration, the lifting component 41 drives the gripper 42 to descend and grab the inner liner 20, allowing for more flexible control over the movement of the inner liner 20.

[0038] As can be seen from the above, when the copper billet is melted into molten copper, the lifting component 41 drives the gripper 42 to descend, the gripper 42 holds the hanging ear 21, the lifting component 41 rises and brings the inner liner 20 out of the outer shell 10, and then the moving mechanism 30 moves to bring the inner liner 20 to the pouring location.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
