Description

Technical Field

[0001] This utility model relates to the field of medium-frequency induction heating furnace technology, specifically a material turning mechanism for a medium-frequency induction heating furnace. Background Technology

[0002] A medium-frequency induction heating furnace is a device that uses the principle of electromagnetic induction to heat metal materials. It is widely used in metal heat treatment, forging, welding, and through-heating. The furnace generates a medium-frequency current through a medium-frequency power supply, which in turn generates an alternating magnetic field through an induction coil. When a metal workpiece is placed inside the induction coil, the alternating magnetic field induces eddy currents within the workpiece. These eddy currents cause free electrons within the workpiece to move at high speed within the metal lattice, thereby generating heat and heating the workpiece.

[0003] Currently, existing medium-frequency induction heating furnaces require pouring molten metal from the furnace into a mold to form the workpiece. However, during the furnace's unloading process, as the amount of molten metal in the mold increases, the furnace's rotation speed needs to be reduced to prevent the molten metal from overflowing from the outlet. Currently, the furnace's rotation is typically controlled by a geared motor, which has a fixed speed. Therefore, it is difficult to control the furnace's rotation speed later on, resulting in significant waste of molten metal. Utility Model Content

[0004] The purpose of this invention is to provide a material turning mechanism for a medium-frequency induction heating furnace to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A material-turning mechanism for a medium-frequency induction heating furnace includes:

[0007] Mobile vehicle;

[0008] The heating furnace body is located above the mobile vehicle and is capable of heating and melting the workpiece;

[0009] A blocking mechanism is disposed between two opposing sides of the heating furnace body, which can block the opening of the heating furnace body. The blocking mechanism includes a blocking plate that moves within the heating furnace body.

[0010] A moving mechanism, located at one end of the top surface of a moving vehicle, is capable of controlling the movement of the mold. The moving mechanism includes an adjusting component fixedly connected to the top surface of the moving vehicle. A fixing component capable of fixing the mold is fixedly connected to the top surface of the adjusting component. The adjusting component includes a placement plate that slides on the top surface of the moving vehicle. The fixing component includes a fixing ring fixedly connected to the top surface of the placement plate. The fixing ring has two symmetrical clamps that are in contact with the placement plate inside.

[0011] Furthermore, fixing blocks are fixedly connected to both opposite sides of the heating furnace body, a vertical rod is fixedly connected to the top surface of the blocking plate, a C-shaped plate is fixedly connected to the top of the vertical rod, and a hydraulic cylinder fixedly connected to the C-shaped plate is fixedly connected through the top of the fixing block.

[0012] Furthermore, the mobile vehicle has support plates fixedly connected to both sides of one end of its top surface. The top of the opposite side of the two support plates is connected to a rotating shaft that is fixedly connected to the heating furnace body. A reduction motor is fixedly connected to the side of one of the support plates. The output end of the reduction motor passes through the support plate at the corresponding position and is fixedly connected to the rotating shaft at the corresponding position.

[0013] Furthermore, the outer side of the clamping plate is rotatably connected to a bolt that screws through and engages with the fixing ring.

[0014] Furthermore, the top surface of the mobile vehicle is fixedly connected to two symmetrical support blocks, and a screw is rotatably connected between the two support blocks. The bottom surface of the placement plate is fixedly connected to a fixing plate that is screwed through the screw.

[0015] Furthermore, one end of the screw passes through a support block near the heating furnace body and is fixedly connected to a connecting rod. A round rod is rotatably connected between the two support plates. One end of the connecting rod is fixedly connected to a bevel gear one, and the outer wall of the round rod is fixedly connected to a bevel gear two that meshes with bevel gear one.

[0016] Furthermore, the top surface of the mobile vehicle is fixedly connected to both sides of a rectangular frame, and a sliding rod is fixedly connected between the two ends of the inner side of the rectangular frame. The bottom surface of the placement plate is fixedly connected to two fixed plates that slide through the sliding rod at the corresponding position.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. By blocking the opening of the heating furnace body with a blocking plate, the molten metal is prevented from overflowing from the opening, so that the molten metal can only flow out from the discharge nozzle at the top of the heating furnace body. This can avoid the waste of molten metal and prevent the molten metal from splashing out of the heating furnace body due to shaking, thereby preventing the molten metal from scalding the staff.

[0019] 2. The mold is clamped and fixed by two bolts and two clamping plates, which can prevent the mold from falling over due to external factors when pouring molten metal. When pouring molten metal, the rotation of the screw can control the movement of the placement plate. The moving placement plate can drive the mold to move, so as to control the distance between the mold and the heating furnace body according to the tilt angle of the heating furnace body, so that the workers can pour the molten metal into the mold more accurately.

[0025] 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.

[0026] Please see Figure 1-4 In this embodiment of the present invention, a material turning mechanism for a medium-frequency induction heating furnace includes a moving cart 1, a heating furnace body 2, a blocking mechanism 3, and a moving mechanism 4. The moving cart 1 supports the entire device and moves the entire device. The heating furnace body 2 for heating and melting workpieces is arranged above the moving cart 1. A blocking mechanism 3 is arranged between the two opposite sides of the heating furnace body 2 to block the opening of the heating furnace body 2. The blocking mechanism 3 includes a blocking plate 31 that moves inside the heating furnace body 2. A moving mechanism 4 for controlling the movement of the mold is arranged at one end of the top surface of the moving cart 1. The moving mechanism 4 includes an adjustment component fixedly connected to the top surface of the moving cart 1. A fixing component for fixing the mold is fixedly connected to the top surface of the adjustment component.

[0027] Specifically, firstly, the blocking plate 31 is removed from the interior of the heating furnace body 2. Then, the workpiece to be heated and melted is placed inside the heating furnace body 2. The workpiece is heated and melted by the heating furnace body 2. After the workpiece is completely melted, the mold is placed in the fixing assembly and fixed. Then, the heating furnace body 2 is rotated to slowly tilt the heating furnace body 2 and pour the molten metal inside into the mold. Since the molten metal inside the heating furnace body 2 decreases as it is poured, the heating furnace body 2 needs to be tilted at a greater angle. At this time, the mold movement can be controlled by adjusting the assembly to ensure that the molten metal poured into the heating furnace body 2... The molten metal can be poured into the mold. When pouring the molten metal, the opening of the heating furnace body 2 is blocked by the blocking plate 31 to prevent the molten metal from overflowing from the opening. This allows the molten metal to flow out only from the discharge nozzle at the top of the heating furnace body 2 (since the top of the heating furnace body 2 is an open structure, the workpiece to be melted is usually placed inside the heating furnace body 2, and the opening of the heating furnace body 2 usually has a pointed discharge nozzle to facilitate pouring the molten metal out of the heating furnace body 2). Therefore, waste of molten metal can be avoided, and molten metal can be prevented from splashing out of the heating furnace body 2 due to shaking, thereby preventing molten metal from scalding the workers.

[0028] Example 1

[0029] like Figure 3 As shown, in this embodiment, fixing blocks 21 are fixedly connected to both opposite sides of the heating furnace body 2, a vertical rod 32 is fixedly connected to the top surface of the blocking plate 31, a U-shaped plate 33 is fixedly connected to the top of the vertical rod 32, and a hydraulic cylinder 34 fixedly connected to the U-shaped plate 33 is fixedly connected through the top of the fixing block 21.

[0030] In this embodiment, the movement of the blocking plate 31 can be controlled by driving the two hydraulic cylinders 34, so that when the operator pours molten metal, the blocking plate 31 can block the opening of the heating furnace body 2 to prevent the molten metal from overflowing.

[0031] Example 2

[0032] like Figure 2 As shown, in this embodiment, support plates 12 are fixedly connected to both sides of one end of the top surface of the mobile vehicle 1. The top of the opposite side of the two support plates 12 is rotatably connected to a rotating shaft that is fixedly connected to the heating furnace body 2. A reduction motor 13 is fixedly connected to the side of one of the support plates 12. The output end of the reduction motor 13 passes through the support plate 12 at the corresponding position and is fixedly connected to the rotating shaft at the corresponding position.

[0033] In this embodiment, the furnace body 2 can be rotated between the two support plates 12 by the drive of the geared motor 13, which makes it easier to tilt the furnace body 2 to pour out the molten metal inside.

[0034] Example 3

[0035] like Figure 4 As shown, in this embodiment, the adjustment assembly includes a placement plate 41 that slides on the top surface of the mobile vehicle 1, and the fixing assembly includes a fixing ring 42 fixedly connected to the top surface of the placement plate 41. The fixing ring 42 has two symmetrical clamping plates 421 inside that abut against the placement plate 41. Bolts that penetrate and screw into the fixing ring 42 are rotatably connected to the outer sides of the clamping plates 421. Two symmetrical support blocks 11 are fixedly connected to the top surface of the mobile vehicle 1, and a screw 43 is rotatably connected between the two support blocks 11. A fixing plate 411 that penetrates and screws into the screw 43 is fixedly connected to the bottom surface of the placement plate 41. One end of the screw 43 passes through the support block 11 near the heating furnace body 2 and is fixedly connected to the connecting rod 431. A round rod 44 is rotatably connected between the two support plates 12. One end of the connecting rod 431 is fixedly connected to a bevel gear 432. A bevel gear 441 that meshes with the bevel gear 432 is fixedly connected to the outer wall of the round rod 44. A rectangular frame 45 is fixedly connected to both sides of the top surface of the moving vehicle 1. A sliding rod is fixedly connected between the two ends of the inner surface of the rectangular frame 45. A fixed plate 412 that slides through the sliding rod at the corresponding position is fixedly connected to both ends of the bottom surface of the placement plate 41.

[0036] In this embodiment, the mold is first clamped and fixed by two bolts using two clamping plates 421, which can prevent the mold from tipping over due to external factors when pouring molten metal. When pouring molten metal, the rotation of the screw 43 can control the movement of the placement plate 41. The moving placement plate 41 can drive the mold to move, thereby controlling the distance between the mold and the heating furnace body 2 according to the tilt angle of the heating furnace body 2, so that the operator can pour the molten metal into the mold more accurately.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
