Description

Technical Field

[0001] This utility model relates to the field of placement rack technology, and in particular to a placement rack for workpieces processed in a high-temperature resistance furnace. Background Technology

[0002] An electric resistance furnace is an industrial furnace that uses electric current to heat heating elements or a heating medium inside the furnace, thereby heating workpieces or materials. It utilizes the heat generated by the passage of electric current through a resistive material. In the machinery industry, electric resistance furnaces are used for heating metals before forging, heating metals during heat treatment, brazing, powder metallurgy sintering, glass and ceramic calcination and annealing, melting low-melting-point metals, and drying sand molds and paint films, among other applications.

[0003] Existing high-temperature resistance furnaces heat workpieces to extremely high temperatures, requiring extra care and posing a significant danger when removing them. Typically, clamps are used to hold the workpieces in place before removal. However, many workpieces soften after being exposed to high temperatures, and directly clamping them may cause surface deformation. Therefore, it is necessary to wait for the workpieces to cool down before removing them for the next batch of workpieces to be heated. This significantly impacts the processing efficiency of the high-temperature resistance furnace. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a workpiece placement rack for high-temperature resistance furnace processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A workpiece placement rack for high-temperature resistance furnace processing includes a high-temperature resistance furnace, a fixed frame fixedly installed on the outside of the high-temperature resistance furnace, a controller fixedly installed on the outside of the fixed frame, a connecting frame provided on the top of the fixed frame, a threaded rod movably installed in the middle of the connecting frame, a movable arm movably installed on the threaded rod, the threaded rod and the movable arm being threadedly connected, movable covers fixedly welded to the bottom of both ends of the movable arm, a fixed rod fixedly welded to the middle position of the bottom of the movable cover, a connecting ring movably sleeved on the outside of the fixed rod, and a placement tray fixedly installed on the outside of the connecting ring.

[0007] As a further embodiment of this utility model, a movable block is fixedly installed at the bottom of the connecting frame, a grooved block is fixedly installed at the top of the fixed frame, a groove is opened in the inner circle of the grooved block, the protrusion on the outer side of the movable block can be movably locked in the groove of the grooved block, and a first bevel gear is fixedly installed at the bottom of the movable block.

[0008] As a further embodiment of this utility model, a second bevel gear is provided on the lower right side of the first bevel gear, the second bevel gear meshes with the first bevel gear, and a servo motor is fixedly installed on the side wall of the fixing frame corresponding to the position of the second bevel gear, the output end of the servo motor penetrates the fixing frame and is fixedly connected to the second bevel gear.

[0009] As a further embodiment of this utility model, a fixing cover is fixedly installed on the outer side of the connecting ring, a limiting rod is movably installed in the fixing cover, the top end of the limiting rod extends through the connecting ring to the side wall of the fixing rod, a stop block is movably installed in the fixing cover, the stop block is fixedly installed on the side wall of the limiting rod, and a spring is fixedly installed between the right side of the stop block and the inner wall of the fixing cover.

[0010] As a further embodiment of this utility model, the side wall of the fixing rod is provided with vertically equidistant limiting grooves, and the top end of the limiting rod can be inserted into the limiting groove.

[0011] As a further embodiment of this utility model, a drive motor is fixedly installed on the top of the connecting frame, and the output end of the drive motor is fixedly connected to the top of the threaded rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, starting the drive motor rotates the threaded rod, which in turn moves the movable cover upward via the movable arm. The movable cover moves the placement tray upward as well, on which the heat-treated workpiece is placed. When the movable arm moves to the top of the connecting frame, the second bevel gear drives the first bevel gear to rotate, controlling the connecting frame to rotate 180°. This moves the movable cover on the right end of the movable arm above the high-temperature resistance furnace. The placement tray below this movable cover holds the untreated workpiece. The movable arm then moves the untreated workpiece into the high-temperature resistance furnace for heat treatment, while the treated workpiece on the placement tray below the left end of the movable arm cools outside the high-temperature resistance furnace. This eliminates the need to wait for the heated workpiece to cool before proceeding with the next batch of workpieces, thus avoiding affecting the processing efficiency of the high-temperature resistance furnace.

[0022] Reference Figure 1 - Figure 4A workpiece placement rack for high-temperature resistance furnace processing includes a high-temperature resistance furnace 1, a fixed frame 2 fixedly installed on the outside of the high-temperature resistance furnace 1, a controller 3 fixedly installed on the outside of the fixed frame 2, a connecting frame 4 set on the top of the fixed frame 2, a threaded rod 5 movably installed in the middle of the connecting frame 4, a movable arm 7 movably installed on the threaded rod 5, and a threaded connection between the threaded rod 5 and the movable arm 7. Movable covers 8 are fixedly welded to the bottom of both ends of the movable arm 7, a fixed rod 16 is fixedly welded to the middle position of the bottom of the movable cover 8, a connecting ring 9 is movably sleeved on the outside of the fixed rod 16, and a placement plate 10 is fixedly installed on the outside of the connecting ring 9. The threaded rod 5 and the movable arm 7 are threadedly connected, and the movable arm 7 is limited by the connecting frame 4 and cannot rotate. At this time, the threaded rod 5 can control the movable arm 7 to move up and down in the connecting frame 4 by changing the rotation direction. The movable arm 7 can drive the movable cover 8 to move up, and the movable cover 8 will drive the placement plate 10 to move up together.

[0023] In this embodiment, a movable block 13 is fixedly installed at the bottom of the connecting frame 4, and a groove block 12 is fixedly installed at the top of the fixed frame 2. The inner ring of the groove block 12 has a groove, and the protrusion on the outer side of the movable block 13 can be movably locked in the groove of the groove block 12. A first bevel gear 14 is fixedly installed at the bottom of the movable block 13, and a second bevel gear 15 is provided on the lower right side of the first bevel gear 14. The second bevel gear 15 meshes with the first bevel gear 14. A servo motor 11 is fixedly installed on the side wall of the fixed frame 2 at the position corresponding to the second bevel gear 15. The output end of the servo motor 11 penetrates the fixed frame 2 and is fixedly connected to the second bevel gear 15. When the servo motor 11 is started, it drives the second bevel gear 15 to rotate. Since the second bevel gear 15 meshes with the first bevel gear 14, the second bevel gear 15 will drive the first bevel gear 14 to rotate. The first bevel gear 14 is fixed on the movable block 13, so the movable block 13 can drive the connecting frame 4 to rotate.

[0024] In this embodiment, a fixing cover 18 is fixedly installed on the outer side of the connecting ring 9. A limiting rod 19 is movably installed in the fixing cover 18. The top end of the limiting rod 19 penetrates the connecting ring 9 and extends to the side wall of the fixing rod 16. A stop block 20 is movably installed in the fixing cover 18. The stop block 20 is fixedly installed on the side wall of the limiting rod 19. A spring 21 is fixedly installed between the right side of the stop block 20 and the inner wall of the fixing cover 18. Limiting grooves 17 are vertically and equidistantly opened on the side wall of the fixing rod 16. The top end of the limiting rod 19 can be inserted into the limiting groove 17. By pulling the top end of the limiting rod 19 out of the limiting groove 17, the movement of the connecting ring 9 on the outside of the fixing rod 16 can be controlled. This allows the distance between the placement trays 10 to be adjusted according to the height of the workpiece being processed, improving the flexibility of the equipment and increasing its application range.

[0025] In this embodiment, a drive motor 6 is fixedly installed on the top of the connecting frame 4. The output end of the drive motor 6 is fixedly connected to the top of the threaded rod 5. Starting the drive motor 6 can drive the threaded rod 5 to rotate.

[0026] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In use, after the workpiece in the high-temperature resistance furnace 1 has been heated, the controller 3 can control the drive motor 6 to start. Starting the drive motor 6 can drive the threaded rod 5 to rotate. Since the threaded rod 5 is threadedly connected to the movable arm 7, and the movable arm 7 is limited by the connecting frame 4 and cannot rotate, the threaded rod 5 can control the movable arm 7 to move up and down in the connecting frame 4 by changing the rotation direction. The movable arm 7 can drive the movable cover 8 to move up, and the movable cover 8 will drive the placement tray 10 to move up together. The placement tray 10 has the heated workpiece placed on it. When the movable arm 7 moves to the top of the connecting frame 4, the placement tray 10 with the workpiece will be completely removed from the high-temperature resistance furnace 1. Then, the servo motor 11 is started to drive the second bevel gear 15 to rotate. Because the second bevel gear 15 meshes with the first bevel gear 14, the second bevel gear 15 will drive the first bevel gear 14 to rotate. The first bevel gear 14 is fixed on the movable block 13. At this time, the movable block 13 can drive the connecting frame 4 to rotate. Control the connecting frame 4 to rotate 180°, so that the movable cover 8 at the right end of the movable arm 7 moves to the top of the high temperature resistance furnace 1. The unheated workpiece is placed on the placement tray 10 below the movable cover 8. Then, the drive motor 6 is started to reverse and control the movable arm 7 to move down. The movable arm 7 will carry the untreated workpiece into the high temperature resistance furnace 1 for heating. The treated workpiece on the placement tray 10 below the left end of the movable arm 7 will be cooled on the outside of the high temperature resistance furnace 1. This achieves the goal of not having to wait for the heated workpiece to cool down before heating the next batch of workpieces, thus avoiding affecting the processing efficiency of the high temperature resistance furnace 1.

[0027] By pulling the top of the limiting rod 19 out of the limiting groove 17, the movement of the connecting ring 9 and the outer side of the fixing rod 16 can be controlled, thereby adjusting the distance between the placement trays 10 according to the height of the workpiece being processed, improving the flexibility of the equipment and increasing its application range.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
