[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted" and "connected" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0021] like Figures 1 to 3 As shown, an embodiment of the present invention provides a tungsten rod sintering anti-deformation device, including a fixed plate 1 and a support rod 2. The fixed plate 1 is provided with a plurality of mounting holes 11 and a plurality of support holes 12 for the tungsten rod 3 to be sintered to pass through.
[0022] There are multiple fixing plates 1 , which are arranged in multiple layers. The supporting holes 12 on each layer of the fixing plates 1 are arranged opposite to each other, so that the tungsten rod 3 can pass through each layer of the fixing plates 1 in sequence.
[0023] A support rod 2 is provided under each layer of the fixed disk 1. The upper end of the support rod 2 passes through the mounting hole 11. The lower surface of the fixed disk 1 abuts against the support rod 2. The support rod 2 supports the fixed disk 1 upward. The mounting holes 11 on each layer of the fixed disk 1 are arranged relatively to each other up and down, so that the support rods 2 of each layer are also arranged relatively to each other up and down. The upper and lower adjacent support rods 2 can be detachably connected. Specifically, the lower end of the support rod 2 of the upper layer can be detachably connected to the upper end of the support rod 2 of the lower layer opposite to it.
[0024] Based on the above scheme, by setting up multiple layers of fixed disks 1, the support holes 12 on each layer of fixed disks 1 are arranged relatively up and down, so that the tungsten rod 3 can pass through the support holes 12 of each layer of fixed disks 1 in sequence. When the tungsten rod 3 is sintered, each layer of fixed disks 1 limits different parts of the length direction of the tungsten rod 3 respectively, thereby preventing the tungsten rod 3 from deforming; the fixed disk 1 is supported by setting support rods 2, and a support rod 2 is provided under each layer of fixed disk 1, and the upper end of the support rod 2 passes through the mounting hole 11. The mounting holes 11 on each layer of fixed disks 1 are arranged relatively up and down, and the upper and lower adjacent support rods 2 can be detachably connected. In this way, when installing the tungsten rod sintering anti-deformation device, each layer of support rods 2 and each layer of fixed disks 1 can be placed in sequence from bottom to top, and the support rods 2 can support and limit each layer of fixed disks 1.
[0025] Specifically, during installation, the bottom support rod 2 can be placed in the sintering furnace and positioned first, and then the bottom fixed plate 1 can be placed on the upper end of the support rod 2. The upper end of the bottom support rod 2 passes through the bottom fixed plate 1 upward, and then the second support rod 2 is connected to the bottom support rod 2, and then the second fixed plate 1 is placed on the upper end of the second support rod 2, and so on, until all layers of fixed plates 1 are installed.
[0026] The aforementioned tungsten rod sintering anti-deformation device, placed within the sintering furnace, limits the position of the tungsten rod 3, improving its support strength and reducing deformation during sintering. This eliminates the need for a subsequent straightening process. Typically, straightening requires heating the tungsten rod 3 to over 1600°C, taking 1-2 hours and requiring hydrogen protection. This consumes significant amounts of electricity, hydrogen, time, and manpower. Furthermore, the surface of the tungsten rod 3 oxidizes during straightening, significantly impacting production efficiency and reducing yield. Eliminating the straightening process saves labor, electricity, and hydrogen costs, reduces oxidation losses, and improves the yield of finished products.
[0027] In some embodiments, the upper and lower adjacent support rods 2 are plugged in, and the lower end of the upper support rod 2 is sleeved on the upper end of the lower support rod 2. Specifically, Figure 3 Shows different layers of support rods 2, combined Figure 1 and Figure 3 As shown, the diameter of the upper end of the support rod 2 is smaller than that of the other portions. This smaller diameter portion of the upper end of the support rod 2 can pass through the mounting hole 11, while the diameter of the other portions is larger than that of the mounting hole 11, thereby being able to abut the lower surface of the fixed plate 1. The lower end of the upper support rod 2 is provided with an opening into which the upper end of the lower support rod 2 can be inserted. In the figure, except for the support rods 2 in the bottom layer, which do not have an opening, the lower ends of the support rods 2 in the other layers are provided with an opening.
[0028] In some embodiments, as Figures 1 to 3 As shown, the fixing plate 1 has three layers, and accordingly, the supporting rods 2 also have three layers. Each layer of supporting rods 2 has six, and accordingly, each fixing plate 1 is provided with six mounting holes 11.
[0029] In some embodiments, as Figure 2 As shown, the fixing plate 1 includes two semi-circular plates 13, which are provided with a plurality of mounting holes 11 and a plurality of supporting holes 12. The fixing plate 1 is configured to have two semi-circular plates 13 for easy installation. During installation, the two semi-circular plates 13 are spliced into a circle in the sintering furnace.
[0030] In some embodiments, the fixing plate 1 and the support rod 2 are both made of tungsten material, thereby ensuring the purity of the environment in the sintering furnace when the tungsten rod 3 is sintered, and preventing impurities from affecting the product quality of the tungsten rod 3 .
[0031] An embodiment of the present utility model further provides a sintering device, comprising a sintering furnace and a tungsten rod sintering anti-deformation device as described in any of the above solutions, wherein the tungsten rod sintering anti-deformation device is arranged in the sintering furnace.
[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
