DETAILED DESCRIPTION

[0027] Although the present invention may be described with respect to a specific application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those skilled in the art will recognize that terms such as "above," "below," "upwardly," "downwardly," and the like are used to describe the drawings and are not intended to limit the scope of the present invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and are not intended to limit the scope of the present invention in any way.

[0028] A copper-magnesium alloy smelting and processing device, such as Figure 1 and Figure 2 As shown, it includes a mounting plate 1, a mounting frame 2, an insulation frame 3, a smelting crucible 4, a smelting mechanism 5 and a dumping mechanism 6. The left and right sides of the mounting plate 1 are connected to the mounting frames 2. The sides of the mounting frames 2 that are close to each other are rotatably connected to the insulation frame 3. The smelting crucible 4 is connected inside the insulation frame 3. The front end of the smelting crucible 4 is designed with a guide nozzle to facilitate the outflow of the copper-magnesium alloy liquid. The insulation frame 3 can block the heat emitted by the smelting crucible 4 to prevent excessive heat from causing burns to workers. The smelting crucible 4 is used to smelt the copper-magnesium alloy. The left mounting frame 2 is provided with a smelting mechanism 5 for heating the smelting crucible 4. A dumping mechanism 6 is provided on the right mounting frame 2, which can adjust the unloading method according to the required amount of alloy; when the copper-magnesium alloy needs to be smelted and processed, this device can quickly assist people in processing and unloading the copper-magnesium alloy. First, the copper-magnesium solid is poured into the smelting crucible 4, and then the smelting crucible 4 is heated and heated by the smelting mechanism 5, so that the copper-magnesium alloy is melted and liquefied. In this process, the insulation frame 3 can prevent the heat emitted by the smelting crucible 4 from scalding people around it. Then, the smelting crucible 4 is rotated by the dumping mechanism 6, so that the copper-magnesium alloy liquid in the smelting crucible 4 can be automatically poured out and unloaded.

[0029] like Figure 1 and Figure 3 As shown, the smelting mechanism 5 includes a fixed plate 51, a control cabinet 52, a connecting line 53 and an inductor 54. The left side of the left mounting frame 2 is welded with a fixed plate 51, and the top of the fixed plate 51 is connected to the control cabinet 52 by bolts. The control cabinet 52 is used to control the power supply. The inductor 54 is wound around the outer side of the lower part of the smelting crucible 4 to heat the smelting crucible 4. Two connecting lines 53 are connected between the inductor 54 and the control cabinet 52 for conducting current. When the smelting crucible 4 needs to be heated quickly, the current is released through the control cabinet 52. All of the current will be conducted to the inductor 54 through the connecting wire 53, so that the inductor 54 starts to heat up, thereby heating the melting crucible 4. Since the inductor 54 is wrapped around the melting crucible 4, the temperature of the melting crucible 4 is relatively uniform. At the same time, the current heating method will also accelerate the heating speed. When the heating is completed, the current can be turned off by operating the control cabinet 52. In summary, the current is released through the control cabinet 52, so that the inductor 54 can be energized for heating, thereby achieving the effect of quickly and evenly heating the melting crucible 4.

[0030] like Figure 1 and Figure 4As shown, the dumping mechanism 6 includes a mounting shell 61, a worm gear 62, a worm 63, a rocking member 64 and a motor 65. The upper part of the right mounting frame 2 is connected to the mounting shell 61, and the bottom of the mounting shell 61 is rotatably connected to the worm 63. The right side of the melting crucible 4 is connected to the worm gear 62, and the right side of the melting crucible 4 passes through the mounting shell 61. The worm gear 62 and the worm 63 are meshed with each other. The rear end of the worm 63 is connected to the rocking member 64, which is convenient for people to slowly rotate the melting crucible 4 so that the smelted alloy liquid slowly flows out. The top of the right mounting frame 2 is connected to the motor by bolts. 65, the output shaft of the motor 65 is connected to the worm 63, and the motor 65 can quickly dump the melting crucible 4; when the copper-magnesium alloy solid is heated and melted into liquid by the melting mechanism 5, the copper-magnesium alloy liquid needs to be poured out and collected. Because the melting crucible 4 is always in a heated state, manually pushing the melting crucible 4 may cause injuries to workers. Therefore, the speed of unloading needs to be selected according to the needs. If the copper-magnesium alloy liquid needs to be poured out slowly and the amount to be poured out each time is small, the shaking piece 64 is manually rotated to The worm 63 drives the worm wheel 62 to rotate, thereby causing the smelting crucible 4 to slowly rotate forward and tilt, so that the copper-magnesium alloy liquid in the smelting crucible 4 can flow out. By rotating the rocking member 64, it is convenient for people to control the amount of liquid poured out. After the material is unloaded, the rocking member 64 is rotated in the opposite direction, so that the worm 63 drives the worm wheel 62 to rotate and reset, thereby causing the smelting crucible 4 to rotate and reset. If it is necessary to pour out all the solution directly, the motor 65 is directly started, and the output shaft of the motor 65 drives the worm 63 to rotate, thereby causing the worm wheel 62 to drive The smelting crucible 4 rotates to achieve the effect of pouring out all the liquid in the smelting crucible 4. After the unloading is completed, the output shaft of the motor 65 is controlled to rotate in the opposite direction, so that the worm 63 drives the worm wheel 62 to rotate in the opposite direction, and then the smelting crucible 4 is rotated backward and reset. In summary, people can choose the pouring method according to the amount of copper-magnesium alloy to be poured out. The rocking member 64 and the motor 65 can both turn the smelting crucible 4 over to pour out the copper-magnesium alloy liquid. The former is suitable for pouring a small amount of high-precision, and the latter is suitable for pouring out all the liquid.

[0031] like Figure 1 and Figure 5As shown, a closing mechanism 7 is also included. The closing mechanism 7 includes a first fixing frame 71, a guide member 72, a second fixing frame 73, a torsion spring 74, a cover 75 and a first spring 76. The first fixing frame 71 is connected to the upper side of the rear portion of the mounting frame 2 by bolts. The first fixing frame 71 is connected to the left and right symmetrical guide members 72. The rear side of the insulation frame 3 is rotatably connected to the second fixing frame 73. Two torsion springs 74 are connected between the second fixing frame 73 and the insulation frame 3. The torsion springs 74 are all wound around the second fixing frame 73. The torsion springs 74 all play a reset role for the second fixing frame 73. The front side of the second fixing frame 73 is slidably connected A cover 75 is connected, and the cover 75 is used to seal the melting crucible 4, so that the melting crucible 4 can be heated up faster. The front ends of the guide members 72 are all hook-shaped, so that they can receive the cover 75. The guide members 72 can press the cover 75. The guide members 72 are arc-shaped. Two first springs 76 are connected between the cover 75 and the second fixing frame 73. The first springs 76 are wound around the cover 75. The top ends of the first springs 76 are connected to the cover 75, and the bottom ends of the first springs 76 are connected to the second fixing frame 73. The first springs 76 play a buffering and resetting role for the cover 75.When the crucible 4 is heated, the cover 75 can effectively form a sealed environment for the crucible 4, thereby allowing the temperature in the crucible 4 to rise rapidly. Then, as the crucible 4 drives the insulating frame 3 to flip and tilt forward, the second fixing frame 73 will move. During the movement of the second fixing frame 73, the cover 75 will move forward. Due to the arc design of the guide member 72, the cover 75 will no longer be squeezed by the guide member 72 during the forward movement. In the initial state, the first spring 76 is in a compressed state. When the cover 75 is no longer squeezed, the cover 75 will slide upward under the action of the first spring 76, and thus contact the guide member 72 again. When the hook on the front side of the guide member 72 contacts the cover 75, it will support the cover 75. At this time, as the crucible 4 and the insulating frame 3 continue to rotate, the cover 75 will no longer move, thereby causing the second fixing frame 73 to rotate backward under force, thereby causing the torsion spring 74 to be deformed under force. At this time, the cover 75 will not The top of the melting crucible 4 is then closed, and the copper-magnesium alloy liquid in the melting crucible 4 can flow out smoothly. After the lower material is poured, as the melting crucible 4 and the insulation frame 3 are rotated backward and reset, the second fixing frame 73 will be driven to move backward and reset. In this process, the cover 75 will be disengaged from the hook on the front side of the guide member 72, and then move backward and reset under the guidance of the guide member 72. At this time, the second fixing frame 73 will rotate backward and reset under the action of the torsion spring 74. As the cover 75 continues to move backward, the guide Component 72 presses against cover 75, thereby compressing first spring 76 and allowing cover 75 to once again seal and cover the top of crucible 4. In summary, by sealing and covering crucible 4 with cover 75, the temperature inside crucible 4 can be rapidly increased. The thermal insulation frame 3 then drives the second fixing frame 73 to move, causing cover 75 to gradually and automatically disengage from crucible 4, no longer sealing and covering crucible 4, and facilitating the pouring out of the copper-magnesium alloy liquid in crucible 4.

[0032] like Figure 1 and Figure 6As shown, it also includes a moving mechanism 8, which includes a moving plate 81, a sliding frame 82, a second spring 83, a first guide wheel 84, a second guide wheel 85, a pull rope 86, a third spring 87 and a connecting piece 88. The upper sides of the left and right parts of the mounting plate 1 are connected to the sliding frames 82 by bolts, and the moving plate 81 is slidably connected between the sliding frames 82. The moving plate 81 is used to place the loading mold. Two second springs 83 are connected between the moving plate 81 and the sliding frame 82. The second springs 83 are all wound around the sliding frame 82. The front ends of the second springs 83 are connected to the moving plate 81, and the rear ends of the second springs 83 are connected to the sliding frame 82. The two springs 83 both play a buffering and resetting role for the movable plate 81. The rear side of the mounting plate 1 is rotatably connected to a first guide wheel 84. The rear side of the mounting frame 2 is rotatably connected to a second guide wheel 85. The bottom of the melting crucible 4 is connected to a connector 88, which passes through the heat insulation frame 3. A pull rope 86 is connected between the connector 88 and the movable plate 81. The pull rope 86 is wound around the first guide wheel 84 and the second guide wheel 85. The rear side of the movable plate 81 is connected to two third springs 87, which can play a buffering role for the movable plate 81. When the melting crucible 4 is rotating to unload, the melting crucible 4 will rotate continuously, so the receiving mold also needs to be The first spring 83 is pressed against the second spring 84 and the second spring 85 is pressed against the first spring 84 and the second spring 85 is pressed against the second spring 85. The second spring 83 is pressed against the second spring 85 ... There is a stroke for continued movement to prevent the pull rope 86 from being stretched too much and causing the pull rope 86 to break. Then, as the melting crucible 4 rotates and resets, the connecting member 88 will also move and reset. At this time, the connecting member 88 will release the pull on the pull rope 86. At this time, the pull rope 86 will be in a relaxed state. Under the action of the second spring 83, the movable plate 81 will slide forward and reset, thereby straightening the pull rope 86 again. In summary, the rotation of the melting crucible 4 drives the connecting member 88 to move, so that the pull rope 86 drives the movable plate 81 to slide backward, thereby preventing the copper-magnesium alloy liquid in the melting crucible 4 from spilling out and being able to be stably received and collected.

[0033] like Figure 1 and Figure 7As shown, an exhaust mechanism 9 is also included. The exhaust mechanism 9 includes an exhaust pipe 91, a cooling tank 92 and a valve 93. The top of the cover 75 is connected to the exhaust pipe 91, and the cooling tank 92 is connected to the exhaust pipe 91. The exhaust pipe 91 passes through the cooling tank 92, and the cooling tank 92 can cool the gas in the exhaust pipe 91. Two valves 93 are rotatably connected to the rear side of the cooling pipe. The upper valve 93 is used for water intake and the lower valve 93 is used for drainage. First, the upper valve 93 is rotated to open and condensed water is added to the cooling tank 92. When the melting crucible 4 starts to heat and melt the copper-magnesium alloy, a large amount of hot gas will be generated. The hot gas will enter the cooling tank 92 through the exhaust pipe 91. Under the cooling effect of the condensed water, the gas discharged from the exhaust pipe 91 is cooled. When the melting crucible 4 is finished, the lower valve 93 is rotated to open and the condensed water can be discharged. In summary, the hot gas discharged from the exhaust pipe 91 is cooled by the cooling tank 92 to prevent the hot gas from being directly discharged and increasing the ambient temperature.

[0034] like Figure 1 and Figure 8 As shown, it also includes a positioning mechanism 10, which includes a rotating frame 101, a positioning rod 102 and a fourth spring 103. The rotating frame 101 is rotatably connected to the movable plate 81, and the positioning rod 102 is slidably connected to the rotating frame 101. The positioning rod 102 can position the bearing mold on the movable plate 81 so that the bearing mold can be located in the middle of the movable plate 81. The rear end of the positioning rod 102 is conical in design, which can facilitate the clamping and positioning of the mold. A fourth spring 103 is connected between the positioning rod 102 and the rotating frame 101, and the fourth spring 103 is wound around the positioning rod 102. The front end of the fourth spring 103 is connected to the positioning rod 102, and the rear end of the fourth spring 103 is connected to the rotating frame 101. The fourth spring 103 is fixed The positioning rod 102 plays a buffering and resetting role; in order to avoid the position of the supporting mold placed on the movable plate 81 from being offset, the rotating frame 101 is rotated backward and upright after placing the mold, and then the positioning rod 102 is pressed downward so that the fourth spring 103 is compressed. Under the positioning of the positioning rod 102, the supporting mold can be located in the center position of the movable plate 81 to prevent the liquid from being spilled and wasted due to the offset of the mold position during the discharge process. After the positioning is completed, the rotating frame 101 is rotated forward and reset, and then the positioning rod 102 is released. Under the action of the fourth spring 103, the positioning rod 102 will slide forward and reset. In summary, the supporting mold is positioned by the positioning rod 102 to prevent the position of the mold from being offset, which causes the liquid to be spilled and wasted.
