Description

Technical Field

[0001] This utility model relates to the field of vacuum furnaces, and in particular to a vacuum furnace with a multifunctional auxiliary electrode. Background Technology

[0002] Vacuum furnaces are important equipment for heating and processing materials in a vacuum environment. They are widely used in many fields such as material heat treatment, ceramic sintering, and semiconductor material preparation. With the continuous development of science and technology and the increasing demands of industrial production, the performance and functions of traditional vacuum furnaces are gradually becoming unable to meet the complex process requirements.

[0003] In traditional vacuum furnaces, parts are stationary within the placement frame, and they may be stacked. When parts are stacked, the heat transfer received by the parts at the bottom of the stack is hindered compared to the parts above. This results in significant differences in the degree of heating received by parts in different positions during the vacuum furnace heating process. Furthermore, since some surfaces of the parts are in contact with the placement frame, the heat received by different surfaces of the same part also varies, which affects the processing quality.

[0004] Traditional vacuum furnaces typically connect a voltage source to the shell. In this voltage connection method, ions are transferred from the edge of the shell towards the center. However, this transfer method can lead to uneven ion distribution between the inner and outer rings. This uneven ion distribution severely affects the processing efficiency and product quality of the vacuum furnace. For example, during heat treatment of materials, uneven ion distribution may cause uneven heating of different parts of the material, resulting in inconsistent material properties and affecting the overall quality and performance of the product.

The vacuum furnace body 2 and the vacuum furnace cover 3 are existing technologies and can be implemented by those skilled in the art. As they are existing technologies, they will not be described in detail in this case. A control cabinet 4 is mounted on the left surface of the vacuum furnace body 2. The control cabinet 4 is... The existing technology, which can be implemented by those skilled in the art, will not be described in detail in this case. The control cabinet 4 is directly installed on the ground. The upper surface of the control cabinet 4 is equipped with a conductive component, which enables ions to be transferred from the center to the edge of the shell, making the ion distribution in the inner and outer rings more uniform and ensuring that the material is heated evenly. The upper surface of the vacuum furnace cover 3 is equipped with a leveling component, which can flatten the parts and avoid stacking. The inner wall of the vacuum furnace cover 3 is equipped with a placement component, which facilitates the placement of parts. When the device is in use, it can shake the parts in conjunction with the leveling component, so that the parts are heated evenly.

[0033] Reference Figure 2 , Figure 4 The leveling assembly includes a motor 61, which is existing technology and can be implemented by those skilled in the art. As it is existing technology, it will not be described in detail in this case. The output shaft of the motor 61 is fixedly connected to a connecting rod 62. Starting the motor 61 can drive the connecting rod 62 to rotate. A sprocket 63 is fixedly connected to the outer wall of the connecting rod 62. The connecting rod 62 can drive the sprocket 63 to rotate synchronously. A sprocket 64 is rotatably connected to the lower surface of the vacuum furnace cover 3. The leveling assembly also includes a rotating rod 66. A positioning plate 67 is fixedly connected to the left surface of the rotating rod 66. When the rotating rod 66 rotates, it will drive the positioning plate 67 to rotate. The upper surface of the rotating rod 66 is fixedly connected to the lower surface of the sprocket 64. A round hole is opened on the outer wall of the rotating rod 66 to allow heat to circulate evenly.

[0034] Reference Figure 2 , Figure 4The placement component includes a fixing rod 71, and a placement frame 72 is fixedly connected to the outer wall of the fixing rod 71. The parts can be placed in the placement frame 72. The inner wall of the placement frame 72 is elastically connected to a slide plate 74 through a compression spring 73. The slide plate 74 slides longitudinally. A positioning block 75 is fixedly connected to the upper surface of the slide plate 74. The positioning block 75 and the slide plate 74 slide synchronously.

[0035] Reference Figure 1 , Figure 3 The conductive components include a connecting pipe 51, a support plate 52 fixedly connected to the upper surface of the connecting pipe 51, a conductive rod 53 fixedly connected to the lower surface of the support plate 52, and a hook 54 fixedly connected to the upper surface of the vacuum furnace cover 3. The hooks on the external hangers or lifting devices can be hung on the hooks 54 to lift the vacuum furnace cover 3.

[0036] Reference Figure 2 , Figure 4 The motor 61 is mounted on the upper surface of the vacuum furnace cover 3, which provides support for the motor 61. The connecting rod 62 passes through and is rotatably connected to the upper surface of the vacuum furnace cover 3. The connecting rod 62 and the vacuum furnace cover 3 are in contact. The outer wall of the first sprocket 63 is connected to the second sprocket 64 via the chain 65. The first sprocket 63 and the second sprocket 64 rotate synchronously. The first sprocket 63, the second sprocket 64, and the chain 65 are made of metal and can withstand high temperatures.

[0037] Reference Figure 2 , Figure 4 The upper surface of the fixing rod 71 is fixedly connected to the inner wall of the top of the vacuum furnace cover 3. The rotating rod 66 passes through the upper surface of the slide plate 74 and the upper surface of the placement frame 72. The slide plate 74 is slidably connected to the inner wall of the placement frame 72 and slides longitudinally. One end of the compression spring 73 is fixedly connected to the lower surface of the slide plate 74, and the other end of the compression spring 73 is fixedly connected to the inner wall of the bottom of the placement frame 72. When the slide plate 74 slides down, it will squeeze the compression spring 73 to generate a reaction force. The front surface of the positioning block 75 is set as an arc surface. When the arc surface of the positioning block 75 is squeezed, the positioning block 75 will move downward.

[0038] Reference Figure 1 , Figure 3 The connecting pipe 51 is located on the upper surface of the control cabinet 4. The connecting pipe 51 has an internal circuit for connecting with the conductive rod 53. The middle section of the connecting pipe 51 is a folding pipe that can be folded and unfolded. The conductive rod 53 passes through and is fixedly connected to the upper surface of the vacuum furnace cover 3. The conductive rod 53 passes through the upper surface of the sprocket 64 and the upper surface of the rotating rod 66. The right surface of the support plate 52 is fixedly connected to the left surface of the vacuum furnace cover 3. The support plate 52 and the vacuum furnace cover 3 will move synchronously.

[0039] Working principle: When using this device, first hang the vacuum furnace cover 3 on the hook 54 through the hook on the external hanger or lifting device and open it, and place the parts to be heat treated on the slide plate 74 in the placement frame 72.

[0040] After placing the parts, cover the vacuum furnace cover 3 onto the vacuum furnace body 2 and fix it with bolts to ensure that the sealing material at the connection is sealed. Then start the vacuum furnace body 2 to put the inside of the device into a vacuum state.

[0041] Then, motor 61 is started. The output shaft of motor 61 drives connecting rod 62 to rotate, thereby causing sprocket 1 63 to rotate synchronously. Sprocket 1 63 drives sprocket 2 64 to rotate through chain 65. Sprocket 2 64 drives rotating rod 66 to rotate. Positioning plate 67 on rotating rod 66 rotates accordingly. During rotation, positioning plate 67 intermittently presses the arc surface of positioning block 75, causing positioning block 75 and slide plate 74 to move downward. Sprocket plate 74 presses compression spring 73. When positioning plate 67 and positioning block 75 separate, the reaction force of compression spring 73 pushes slide plate 74 upward, causing slide plate 74 to be in a shaking state, shaking and flattening the parts to avoid stacking. In addition, during the shaking process, different sides of the parts are rotated, so that the parts are heated evenly.

[0042] During the operation of the device, the control cabinet 4, through the connecting pipe 51, conductive rod 53 and other conductive components, enables ions to be emitted from the conductive rod 53. The ions will be transferred from the center to the edge of the shell. Then, in the prior art, the vacuum furnace body 2 is connected to the shell with voltage, and the ions will be transferred from the edge of the shell to the center. This enables the synchronous transfer of ions in the inner and outer rings, making the ion distribution in the inner and outer rings more uniform, ensuring that the material is heated evenly, so as to realize the heat treatment operation of the parts.

[0043] After heat treatment, unscrew the bolts, and then lift and open the vacuum furnace cover 3 by hanging it on hook 54 using the hooks on the external hanger or lifting device, and then remove the parts.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
