[0052] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an independently driven trolley furnace for heat treatment.

[0053] A self-propelled trolley furnace for heat treatment includes a furnace body 1, a control panel 2, and further includes:

[0054] A drive assembly is disposed on the furnace body 1, and the drive assembly includes:

[0055] A drive motor 3 is mounted on the furnace body 1 and is fixedly connected to the furnace body 1;

[0056] A threaded rod 4 is disposed on the furnace body 1 and rotatably connected to the furnace body 1. The threaded rod 4 is fixedly connected to the output shaft of the drive motor 3.

[0057] Guide rod 5 is disposed on the furnace body 1 and fixedly connected to the furnace body 1. There are two guide rods 5, which are symmetrically distributed on the furnace body 1 with the threaded rod 4 as the axis.

[0058] The slider 6 is disposed on the guide rod 5 and slidably connected to the guide rod 5. The slider 6 is threadedly connected to the threaded rod 4. The slider 6 is made of ceramic fiber with high temperature resistance and thermal conductivity of 0.02-0.03 W / m·K.

[0059] The loading platform 7 is mounted on the slider 6 and is fixedly connected to the slider 6.

[0060] Start the drive motor 3. The output shaft of the drive motor 3 rotates, which drives the threaded rod 4, which is fixedly connected to the output shaft of the drive motor 3, to rotate. This drives the slider 6, which is threadedly connected to the threaded rod 4, to rotate. Since the slider 6 is restricted by the slidingly connected and symmetrically distributed guide rods 5, the slider 6 can only slide along the guide rods 5. The sliding of the slider 6 drives the loading platform 7, which is fixedly connected to the slider 6, to slide, which facilitates subsequent work.

[0061] With the arrangement of the drive motor 3, the threaded rod 4, the guide rod 5, the slider 6, and the carrying platform 7, the drive motor 3 rotates the threaded rod 4, causing the slider 6, which is mounted on the guide rod 5, to slide along the guide rod 5 as the threaded rod 4 rotates. This allows the carrying platform 7, mounted on the slider 6, to quickly and smoothly transport large-mass workpieces. Furthermore, because the slider 6 has a low thermal conductivity and slow heat conduction, the temperature difference between the part of the threaded rod 4 located in the heating assembly and other parts is reduced, extending the service life of the threaded rod 4. Consequently, the service life of the trolley furnace's drive assembly under heavy load and high-temperature conditions is extended.

[0062] Reference Figures 1 to 5 A sealing assembly, disposed on the furnace body 1, is used to increase the sealing performance of the bogie furnace. The sealing assembly includes:

[0063] Mounting slot 8 is provided on the furnace body 1;

[0064] A sliding groove 9 is provided on the furnace body 1;

[0065] The first servo motor 10 is mounted on the mounting slot 8 and is fixedly connected to the furnace body 1;

[0066] A sealing door 11 is disposed on the sliding groove 9 and slidably connected to the furnace body 1. The protruding part of the slider 6 is tightly fitted with the groove on the sealing door 11. The surface of the sealing door 11 is coated with a high-temperature resistant heat insulation coating.

[0067] The lead screw 12 is mounted on the output shaft of the first servo motor 10 and is fixedly connected to the output shaft of the first servo motor 10. The lead screw 12 is threadedly connected to the sealing door 11.

[0068] The first servo motor 10 is started by the control panel 2. The output shaft of the first servo motor 10 rotates, which drives the lead screw 12 fixedly connected to the output shaft of the first servo motor 10 to rotate, thereby driving the sealing door 11 threadedly connected to the lead screw 12 to rotate. Since the sealing door 11 is restricted by the sliding connection of the furnace body 1, the sealing door 11 can only slide along the sliding groove 9 on the furnace body 1 until the groove of the sealing door 11 is tightly fitted with the protrusion of the slider 6, so as to achieve the sealing effect.

[0069] Reference Figures 1 to 5A heating assembly, disposed on the furnace body 1, is used for heat treatment. The heating assembly includes:

[0070] Heating device 13 is mounted on the furnace body 1 and is fixedly connected to the furnace body 1;

[0071] The second servo motor 14 is mounted on the furnace body 1 and is fixedly connected to the furnace body 1;

[0072] The first rotating shaft 15 is disposed on the furnace body 1 and rotatably connected to the furnace body 1. The first rotating shaft 15 is fixedly connected to the output shaft of the second servo motor 14.

[0073] The first fan blade 16 is disposed on the first rotating shaft 15 and is fixedly connected to the first rotating shaft 15.

[0074] The heating device 13 is started by controlling panel 2, and the second servo motor 14 is started at the same time. The output shaft of the second servo motor 14 rotates, which drives the first rotating shaft 15 fixedly connected to the output shaft of the second servo motor 14 to move, thereby driving the first fan blade 16 fixedly connected to the first rotating shaft 15 to rotate. The airflow generated by the rotation of the first fan blade 16 will stir the heat in the furnace more evenly, so that the workpiece can be heated evenly.

[0075] Reference Figures 1 to 5 A cooling assembly, disposed on the furnace body 1, is used to cool the workpiece after heat treatment. The cooling assembly includes:

[0076] A heat dissipation vent 17 is provided on the furnace body 1;

[0077] The third servo motor 18 is mounted on the furnace body 1 and is fixedly connected to the furnace body 1;

[0078] The second rotating shaft 19 is disposed on the furnace body 1 and rotatably connected to the furnace body 1. The second rotating shaft 19 is fixedly connected to the output shaft of the third servo motor 18.

[0079] The second fan blade 20 is disposed on the second rotating shaft 19 and is fixedly connected to the second rotating shaft 19.

[0080] The third servo motor 18 is driven, and the output shaft of the third servo motor 18 rotates, which drives the second rotating shaft 19 fixedly connected to the output shaft of the third servo motor 18 to rotate, thereby driving the second fan blade 20 fixedly connected to the second rotating shaft 19 to rotate. The airflow generated by the rotation of the second fan blade 20 quickly carries away the heat on the workpiece and discharges it through the heat dissipation port 17, achieving the effect of rapid cooling after heat treatment.

[0081] Working principle: Refer to Figures 1 to 5Place the workpiece to be heat-treated on the loading platform 7, start the drive motor 3 through the control panel 2. The output shaft of the drive motor 3 rotates, which drives the threaded rod 4 fixedly connected to the output shaft of the drive motor 3 to rotate, thereby driving the slider 6 threadedly connected to the threaded rod 4 to rotate. Since the slider 6 is restricted by the slidingly connected and symmetrically distributed guide rods 5, the slider 6 can only slide along the guide rods 5. The sliding of the slider 6 drives the loading platform 7 fixedly connected to the slider 6 to slide until the loading platform 7 moves to the heating component. Then turn off the drive motor 3 through the control panel 2.

[0082] The first servo motor 10 is started by the control panel 2. The output shaft of the first servo motor 10 rotates, which drives the lead screw 12 fixedly connected to the output shaft of the first servo motor 10 to rotate, thereby driving the sealing door 11 threadedly connected to the lead screw 12 to rotate. Since the sealing door 11 is restricted by the sliding connection of the furnace body 1, the sealing door 11 can only slide along the sliding groove 9 on the furnace body 1 until the groove of the sealing door 11 is tightly fitted with the protrusion of the slider 6. The first servo motor 10 is then turned off by the control panel 2.

[0083] Reference Figures 1 to 5 The heating device 13 is started via the control panel 2, and the second servo motor 14 is started simultaneously. The output shaft of the second servo motor 14 rotates, which drives the first rotating shaft 15 fixedly connected to the output shaft of the second servo motor 14 to move, thereby driving the first fan blade 16 fixedly connected to the first rotating shaft 15 to rotate. The airflow generated by the rotation of the first fan blade 16 stirs the heat in the furnace more evenly, so that the workpiece can be heated evenly. After the heat treatment is completed, the second servo motor 14 and the heating device 13 are turned off. The sealing door 11 is opened via the control panel 2, and the drive assembly is started to transport the workpiece to the cooling assembly. The drive assembly and the sealing door 11 are turned off, and the third servo motor 18 is started. The output shaft of the third servo motor 18 rotates, which drives the second rotating shaft 19 fixedly connected to the output shaft of the third servo motor 18 to move, thereby driving the second fan blade 20 fixedly connected to the second rotating shaft 19 to rotate. The airflow generated by the rotation of the second fan blade 20 quickly carries away the heat on the workpiece and discharges it through the heat dissipation port 17, achieving the effect of rapid cooling after heat treatment.
