[0004] As shown in the above technology, after the aluminum alloy profile melting furnace is finished melting the aluminum alloy profile, the molten metal needs to be discharged. The existing method is to drive the melting furnace to rotate and tilt to discharge the metal. During the tilting process, the melting furnace is stabilized by contact with the rotating component. However, the motor in the rotating component is subjected to a large external force, which is not conducive to long-term use. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a melting furnace for producing aluminum alloy profiles, which solves the problem that the rotating parts of existing melting furnaces are subjected to large external forces when tilted, which is not conducive to long-term use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: A melting furnace for producing aluminum alloy profiles includes a frame and a furnace body. The furnace body is rotatably mounted on the frame. A rotary drive component is provided on the frame to drive the furnace body to rotate. When the furnace body rotates, it discharges the molten aluminum profile metal inside. The frame is internally equipped with two left and right limiting mechanisms, each including:
[0007] A limiting component is used to limit and stabilize the melting furnace body during rotation. The limiting component includes a rotating rod, a limiting tooth, and a torsion spring.

[0008] The locking component is used to lock the position of the limiting component after it has been limited, that is, to lock the position of the melting furnace body after it has stopped rotating, thereby reducing the external force on the rotating drive component.
[0009] Preferably, the limiting component further includes a fixed seat, one side of which is fixedly connected to a fixed rod, and the other end of the fixed rod is rotatably connected to the middle part of the rotating rod.

[0014] Beneficial effects
[0015] This invention provides a melting furnace for producing aluminum alloy profiles. Compared with the prior art, it has the following advantages:
[0016] 1. The melting furnace for producing aluminum alloy profiles uses a limiting component to stabilize the furnace body during rotation. The limiting component includes a rotating rod, limiting teeth, and a torsion spring. The limiting teeth are fixed at the end of the rotating rod. During the rotation and tilting of the melting furnace, the limiting teeth on the rotating rod and the torsion spring in the limiting component stabilize the rotation of the melting furnace and lock its position when the melting furnace stops rotating, thereby reducing the external force on the rotating drive component and facilitating the long-term use of the device.
[0017] 2. The melting furnace for producing aluminum alloy profiles has a pressure sensor fixedly connected to the end of the driven gear by bolts. A controller is installed on the frame, and the signal output terminal of the pressure sensor is connected to the signal input terminal of the controller. When the rotary drive drives the melting furnace to rotate, it rotates to the limit position when the drive gear contacts the pressure sensor, thereby controlling the rotary drive to stop working in time, which improves the automation level of the device.

[0023] 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.
[0024] Please see Figures 1-4 The melting furnace for producing aluminum alloy profiles offers two technical solutions:
[0025] The first embodiment includes a frame 1 and a melting furnace body 2. The melting furnace body 2 is rotatably mounted on the frame 1. The frame 1 is equipped with a rotary drive 3 for driving the melting furnace body 2 to rotate. When the melting furnace body 2 rotates, it discharges the molten aluminum profile metal inside. The frame 1 is equipped with two left and right limiting mechanisms inside. The limiting mechanisms include:
[0026] The limiting component 4 is used to limit and stabilize the melting furnace body 2 during rotation. The limiting component 4 includes a rotating rod 43, a limiting tooth 44, and a torsion spring 45. The limiting tooth 44 is fixed at the end of the rotating rod 43 and can reciprocate under the action of the torsion spring 45. The limiting component 4 also includes a fixed seat 41. A fixed rod 42 is fixedly connected to one side of the fixed seat 41. The other end of the fixed rod 42 is rotatably connected to the middle part of the rotating rod 43. The torsion spring 45 is sleeved on the surface of the fixed rod 42. One end of the torsion spring 45 is fixedly connected to one side of the rotating rod 43, and the other end of the torsion spring 45 is fixedly connected to the surface of the fixed rod 42.
[0027] Locking component 5 is used to lock the position of the limiting component 4 after it is limited, that is, to lock the position of the melting furnace body 2 after it stops rotating, thereby reducing the external force on the rotating drive component 3. Locking component 5 includes a support frame 51, a hydraulic cylinder 52 is fixedly connected to one side of the support frame 51, a guide rod 53 is fixedly connected to the telescopic end of the hydraulic cylinder 52, and two fixing rings 54 are fixedly connected to the surface of the guide rod 53. A guide groove 55 is opened inside the rotating rod 43, and the guide rod 53 passes through the inside of the fixing ring 54. The two fixing rings 54 are distributed on the upper and lower sides of the rotating rod 43.
[0028] During the rotation and tilting of the melting furnace, the limiting teeth 44 on the rotating rod 43 in the limiting assembly 4 cooperate with the torsion spring 34 to stabilize the rotation of the melting furnace and lock its position when the melting furnace stops rotating, thereby reducing the external force on the rotating drive component 3 and facilitating the long-term use of the device.
[0029] The second embodiment differs from the first embodiment in that the rotary drive component 3 includes a drive motor, a drive gear, and a driven gear. The driven gear is fixedly connected to the melting furnace body 2, the drive gear is fixedly connected to the output end of the drive motor, and the drive gear and the driven gear mesh and transmit power. The limiting tooth 44 is located in the tooth gap of the driven gear. A pressure sensor 6 is fixedly connected to the end of the driven gear by bolts. A controller 7 is installed on the frame 1, and the signal output end of the pressure sensor 6 is connected to the signal input end of the controller 7.
[0030] When the rotary drive 3 drives the melting furnace to rotate, it rotates to its limit position when the drive gear contacts the pressure sensor 6, thereby controlling the rotary drive 3 to stop working in time and improving the automation level of the device.
[0031] In operation, the drive motor operates and drives the drive gear to rotate. The drive gear transmits power to the driven gear, which rotates and drives the melting furnace body 2 to rotate, thus tilting the furnace. When the driven gear rotates, its teeth contact the limiting tooth 44 and push the rotating rod 43 to rotate. The rotating rod 43 rotates and causes the torsion spring 45 to twist. The teeth of the driven gear can pass over the limiting tooth 44. After the driven gear stops rotating, the limiting tooth 44 enters the gap between the teeth of the driven gear, thus limiting the rotation. Then, the hydraulic cylinder 52 is activated to make the fixing ring 54 contact the rotating rod 43, thereby making the limiting tooth 44 abut against the driven gear and locking the position of the driven gear, that is, locking the melting furnace body 2. In addition, when the limiting tooth 44 contacts the pressure sensor 6, it indicates that the melting furnace body 2 has rotated to the limit position, thus quickly controlling the drive motor to stop or rotate back.
