Description

Technical Field

[0001] This utility model relates to the field of silicon nitride heating elements, specifically to a tungsten filament treatment device for silicon nitride heating elements. Background Technology

[0002] Silicon carbide heating elements are high-temperature electric heating elements made primarily of high-purity silicon carbide. They are characterized by high temperature resistance, corrosion resistance, and long lifespan. Silicon nitride electric heating elements are electric heating elements made with silicon nitride as the substrate and tungsten wire as the heat source. They are widely used in industrial and household appliances.

[0003] In the production and processing of silicon nitride heating elements, a tungsten wire treatment device is usually used to pre-heat treat the tungsten wires used in the silicon nitride heating elements, thereby ensuring that the tungsten wires have better properties and can be better matched with the silicon nitride substrate.

[0004] Traditional silicon nitride heating element tungsten filament processing devices are cumbersome to fix, making it difficult for operators to quickly and easily fix tungsten filament discs of different specifications onto the processing device for heat treatment. This results in poor flexibility. Furthermore, the distance adjustment between the arc-shaped heating plates in traditional silicon nitride heating element tungsten filament processing devices is complex, making it difficult for operators to easily adjust the distance between the arc-shaped heating plates. Consequently, the arc-shaped heating plates cannot effectively heat treat tungsten filament discs of different specifications fixed on the device, which is detrimental to practical use. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a tungsten wire treatment device for silicon nitride heating elements, so as to solve the technical problems that the existing tungsten wire treatment devices for silicon nitride heating elements have cumbersome fixing operations and complicated distance adjustment operations between arc-shaped heating plates.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tungsten filament treatment device for silicon nitride heating elements, comprising a base, with wheels connected to the four corners of the bottom of the base, support plates on both sides of the top of the base, threaded rods at the center of one side of each of the two support plates, movable holes at the center of the inner cavities of each of the two support plates, one end of each of the two threaded rods penetrating the inner cavity of an adjacent movable hole and connected to a drive plate, an arc-shaped heating plate on one side of each of the two drive plates, the center of the edge of each of the two arc-shaped heating plates being connected to the center of one side of an adjacent drive plate, and a fixing component on one side of each of the two arc-shaped heating plates; the fixing component includes a support plate located at the bottom of one side of the two arc-shaped heating plates, a drive motor at the bottom of the support plate, the bottom of the drive motor being connected to the center of the top of the base, and the top of the drive motor's power output shaft being connected to the center of the bottom of the support plate.

[0007] By adopting the above technical solution, the effect of quickly fixing the tungsten wire disc is achieved, and the effect of conveniently adjusting the distance between the two arc-shaped heating plates is also achieved.

[0008] The present invention is further configured such that a vertical rod is connected to the center of the top of the support plate, and trapezoidal slots are provided on both sides of the vertical rod near the center of the top. Trapezoidal plates are movably connected to the inner cavity of the two trapezoidal slots near the top. One side of each of the two trapezoidal plates passes through the inner cavity of the adjacent trapezoidal slot and is connected to a chuck.

[0009] By adopting the above technical solution, two trapezoidal plates can be pushed into two trapezoidal slots, thereby quickly fixing the chuck to the top of the tungsten wire disc sleeved on the vertical rod. This allows workers to quickly fix tungsten wire discs of different specifications onto the processing device for heat treatment.

[0010] The present invention is further configured such that a grooved wheel is fitted on one end of each of the two threaded rods, and the two grooved wheels are movably connected to the center of one side of an adjacent support plate. A drive hole is opened at the center of the inner cavity of each of the two grooved wheels, and the inner wall of each drive hole is opened with an internal thread that matches the threaded rod. A grooved wheel is also movably connected to the center of the top of one side of each of the two support plates. A belt is provided on both of the two grooved wheels on both sides, and the two grooved wheels on both sides are connected by an adjacent belt drive.

[0011] By adopting the above technical solution, two threaded rods can be driven to move towards an adjacent end. When the two threaded rods move towards an adjacent end, the two drive plates can drive the two arc-shaped heating plates to close together, thereby achieving the purpose of conveniently adjusting the distance between the two arc-shaped heating plates.

[0012] The present invention is further configured such that an adjustment motor is provided on one side of each of the two grooved wheels located at the top, and one end of the power output shaft of each of the two adjustment motors is connected to the center of one side of the adjacent grooved wheel.

[0013] By adopting the above technical solution, when the staff starts the two regulating motors through an external power supply, the two regulating motors can quickly drive the two grooved wheels at the top to rotate in opposite directions when powered on.

[0014] The present invention is further configured such that a connecting rod is connected to the center of one side of each of the two adjusting motors, a positioning plate is connected to one end of each of the two connecting rods, and one side of each of the two positioning plates is connected to the center of one side of an adjacent support plate.

[0019] By adopting the above technical solution, the positions of the two support plates can be defined, so that the components on the two support plates can work stably.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model uses a chuck to place two trapezoidal plates at the top of two trapezoidal slots, and then presses the chuck down to push the two trapezoidal plates into the two trapezoidal slots. This allows the chuck to be quickly fixed to the top of the tungsten wire disc on the vertical rod, thus achieving the effect of quickly fixing the tungsten wire disc. This allows workers to quickly fix tungsten wire discs of different specifications on the processing device for heat treatment, which is highly flexible and easy for workers to operate.

[0022] 2. This utility model drives two grooved wheels at the bottom to rotate in opposite directions, enabling them to move two threaded rods towards an adjacent end.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] Tungsten filament treatment device for silicon nitride heating elements, such as Figures 1-4 As shown, the system includes a base 1, with wheels attached to the four corners of the base 1. Support plates 4 are located on both sides of the top of the base 1. A threaded rod 14 is located at the center of one side of each support plate 4. Movable holes are opened at the center of the inner cavity of each support plate 4. One end of each threaded rod 14 passes through the inner cavity of the adjacent movable hole and is connected to a drive plate 5. An arc-shaped heating plate 6 is located on one side of each drive plate 5. The center of the edge of each arc-shaped heating plate 6 is connected to the center of one side of the adjacent drive plate 5. A fixing component 8 is located on one side of each arc-shaped heating plate 6. The fixing component 8 includes a support plate 81 located at the bottom of one side of each arc-shaped heating plate 6. A drive motor 7 is located at the bottom of the support plate 81. The bottom of the drive motor 7 is connected to the center of the top of the base 1, and the top of the power output shaft of the drive motor 7 is connected to the center of the bottom of the support plate 81.

[0031] When using this processing device to pre-heat treat the tungsten wire used in the silicon nitride heating element, the operator places the tungsten wire disc to be heat-treated onto the vertical rod 82. The operator then fixes the vertical rod 82 to the top of the tungsten wire disc, thus quickly securing it. After fixing the tungsten wire disc onto the base 1, the operator starts two adjusting motors 12 via an external power supply. This moves two drive plates 5 to an adjacent side, causing the two arc-shaped heating plates 6 to close together. This allows for convenient adjustment of the distance between the two arc-shaped heating plates 6, enabling the operator to easily heat the two arc-shaped heating plates. The distance between the plates 6 is adjusted so that the two arc-shaped heating plates 6 can be quickly adjusted to a position where they are close to contacting the tungsten wire disc fixed on the base 1. This allows the two arc-shaped heating plates 6 to better heat treat the tungsten wire disc fixed on the base 1. After the distance between the two arc-shaped heating plates 6 is adjusted, the operator starts the drive motor 7 and the two arc-shaped heating plates 6 through an external power supply. When the two arc-shaped heating plates 6 are powered on, they can perform heat treatment on the tungsten wire disc fixed on the base 1. When the drive motor 7 is powered on, it can drive the tungsten wire disc fixed on the vertical rod 82 to rotate through the support plate 81, thereby enabling heat treatment of the tungsten wire disc over a wide range and improving the heat treatment efficiency of the tungsten wire disc to a certain extent.

[0032] like Figure 1 As shown, each of the two support plates 4 has a support rod 2 connected to its bottom center. The two support rods 2 are symmetrically arranged with the center of the inner cavity of the base 1 as the axis of symmetry, and the bottom ends of the two support rods 2 are respectively connected to the center of the top two sides of the base 1.

[0033] Two support plates 4 are fixed to the center of the top two sides of the base 1 by two support rods 2, thereby limiting the position of the two support plates 4 and enabling the components on the two support plates 4 to work stably.

[0034] like Figure 1 As shown, two T-shaped limiting rods 3 are connected to the center of one side of each of the two drive plates 5, and two limiting holes are opened at the center of one side of each of the two support plates 4. The two T-shaped limiting rods 3 located on both sides are movably connected to the adjacent limiting holes near one end.

[0035] When the two drive plates 5 move toward an adjacent side, they can drive the two adjacent T-shaped limiting rods 3 to slide inside the adjacent limiting holes, thereby limiting the position of the two drive plates 5 and enabling the two drive plates 5 to move smoothly.

[0036] like Figure 1 and Figure 3As shown, each of the two threaded rods 14 is fitted with a grooved wheel 11 near one end, and both grooved wheels 11 are movably connected to the center of one side of the adjacent support plate 4. The center of the inner cavity of each of the two grooved wheels 11 is provided with a drive hole, and the inner wall of each drive hole is provided with an internal thread that matches the threaded rod 14. The center of the top of one side of each of the two support plates 4 is also movably connected with a grooved wheel 11. Both grooved wheels 11 on both sides are provided with a belt 9, and the two grooved wheels 11 on both sides are connected by a transmission through the adjacent belt 9.

[0037] After the worker fixes the tungsten wire disc onto the base 1, the worker starts the two adjusting motors 12 via an external power supply. When energized, the two adjusting motors 12 drive the two top grooved wheels 11 to rotate in opposite directions; the left grooved wheel 11 rotates in the forward direction and the right grooved wheel 11 rotates in the reverse direction. When the two top grooved wheels 11 rotate in opposite directions, they drive the two bottom grooved wheels 11 to rotate in opposite directions via adjacent belts 9. This causes the two bottom grooved wheels 11 to move the two threaded rods 14 towards their adjacent ends. When moving towards the adjacent end, the two drive plates 5 can drive the two arc-shaped heating plates 6 to close together, thereby achieving the purpose of conveniently adjusting the distance between the two arc-shaped heating plates 6. This allows the operator to easily adjust the distance between the two arc-shaped heating plates 6, so that the two arc-shaped heating plates 6 can be adjusted to a position that is close to contacting the tungsten wire discs of different specifications fixed on the base 1. This allows the two arc-shaped heating plates 6 to better perform heat treatment on the tungsten wire discs of different specifications fixed on the base 1, thus facilitating practical use.

[0038] like Figure 1 and Figure 3 As shown, an adjustment motor 12 is provided on one side of each of the two grooved wheels 11 located at the top, and one end of the power output shaft of each of the two adjustment motors 12 is connected to the center of one side of the adjacent grooved wheel 11.

[0039] The staff can start the two regulating motors 12 by connecting an external power source, so that the two regulating motors 12 can quickly drive the two grooved wheels 11 at the top to rotate in different directions when they are powered on.

[0040] like Figure 1 and Figure 3 As shown, each of the two adjusting motors 12 has a connecting rod 13 connected to the center of one side, and each of the two connecting rods 13 has a positioning plate 10 connected to one end. Each of the two positioning plates 10 has one side connected to the center of the adjacent support plate 4.

[0041] Two adjusting motors 12 are fixed to the top of one side of two support plates 4 by two positioning plates 10, thereby limiting the position of the two adjusting motors 12 and enabling the two adjusting motors 12 to work stably.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, a vertical rod 82 is connected to the top center of the support plate 81. Trapezoidal slots are provided on both sides of the vertical rod 82 near the top center. Trapezoidal plates 84 are movably connected to the inner cavity of the two trapezoidal slots near the top. One side of each trapezoidal plate 84 passes through the inner cavity of the adjacent trapezoidal slot and is connected to a chuck 83.

[0043] When workers need to fix tungsten wire discs on the processing device for heat treatment, they first place the discs onto the vertical rod 82. Then, they place two trapezoidal clamping plates 84 at the top of the two trapezoidal clamping slots. Next, they press down on the clamps 83, pushing the two clamping plates 84 into the slots. This quickly fixes the clamps 83 onto the top of the tungsten wire discs on the vertical rod 82, achieving the goal of quickly fixing the tungsten wire discs. This allows workers to quickly fix tungsten wire discs of different specifications onto the processing device for heat treatment, offering high flexibility and ease of operation.
