[0002] A vacuum sintering furnace is a furnace that performs protective sintering on heated objects in a vacuum environment. There are many heating methods, such as resistance heating, induction heating, microwave heating, etc. A vacuum sintering furnace is a furnace that uses induction heating to perform protective sintering on heated objects. It can be divided into industrial frequency, medium frequency, high frequency and other types, which can be classified as a subcategory of vacuum sintering furnaces.
[0003] The vacuum induction sintering furnace is a complete set of equipment that uses the principle of medium frequency induction heating to sinter carbide tool heads and various metal powder compacts under vacuum or protective atmosphere conditions. It is designed for the industrial production of cemented carbide, metal dysprosium, and ceramic materials. Choosing a suitable atmosphere for sintering will help the sintering process, improve the degree of product densification, and obtain products with good performance.
[0004] The problem that most bases are prone to cracking after being under pressure for a long time, affecting the normal operation of the airway and causing uneven heating of the material, and the carrier plate is not stably placed and is prone to tipping over, requiring frequent replacement of the base, has not been solved. The prior art proposes a sintering furnace support structure, as recorded in patent CN219572619U, a base, which is provided with a base, the base is provided with a mounting hole, a support column, which is arranged in the mounting hole, one end of the support column is connected to the base, the height of the support column is greater than the height of the base, a carrier plate, which contacts with the other end of the support column, a pressure-proof space is formed between the carrier plate and the base, the end of the support column close to the base contacts with the base, and the support column can be moved along the mounting hole. The hole moves in the direction of the hole, thereby separating from the base, and also includes a bushing, the bushing is arranged in the mounting hole and fixedly connected to the mounting hole, the support column is movably connected to the bushing, the support column is slidably connected to the bushing, the bushing is provided with an internal thread, the support column is provided with an external thread, the external thread of the support column is threadedly connected with the internal thread of the bushing, the base is a ceramic fiber part, the support column is an aluminum oxide part, the bushing is an aluminum oxide part, the height of the bushing is greater than the height of the base, the height of the support column is greater than the height of the bushing, the base is provided with an airway, the number of the mounting holes is at least two, and the two mounting holes are respectively located on both sides of the airway;
[0005] However, in this utility model, the carrier plate can only be connected to the support column in the form of contact with one end thereof when placed, and cannot achieve a good stabilization effect. In addition, the carrier plate is divided into blocks, which is not easy to position and needs to be aligned during installation, which affects work efficiency.
[0006] Therefore, there is an urgent need for a support structure for a sintering furnace that can effectively determine the position of the carrier plate during disassembly and replacement and reduce instability during installation and use. Utility Model Content
[0007] In view of the above technical problems, the utility model provides a support structure for a sintering furnace, which realizes the function of effectively determining the position of a carrier plate during disassembly and replacement, and reducing instability during installation and use.
[0008] The utility model is characterized in that it comprises a base structure, a column structure and a bearing structure, wherein the base structure is plugged with the column structure, and the bearing structure is plugged with the column structure.
[0009] The base structure is composed of a base and a pedestal. The base is installed on the base, and the base is provided with an airway and a plug hole.
[0010] The column structure consists of a bushing, a support column, and a threaded portion. A thread is provided inside the bushing. The bushing is threadedly connected to the threaded portion. The upper end of the threaded portion is connected to the support column. The threaded portion and the support column are integrally formed. The bushing can be inserted into the socket.
[0011] The bearing structure is composed of a carrier plate and a limiting sleeve. There are four carrier plates. A limiting sleeve is installed at the lower end of the carrier plate. There are multiple limiting sleeves. A limiting hole is arranged at the lower end of the limiting sleeve, and the surface of the limiting hole is an inclined surface.
[0012] The beneficial effects of the utility model are:
[0013] The utility model adds a limiting sleeve on the original basis, and opens a limiting hole at the lower end of the limiting sleeve, so as to effectively determine the position of the carrier plate when disassembling and replacing, and reduce the instability during installation and use.
[0014] The limiting sleeve, limiting hole and support column cooperate to position the carrier. The surface of the limiting hole is an inclined surface, which can guide the placement of the carrier. When the placement is inaccurate, the top of the support column can slide into the limiting hole along the inclined surface to avoid the operator's inconvenience in installing the support column and the resulting reduction in efficiency. The limiting sleeve can also effectively position the carrier to avoid the upper device driving the carrier off when moving, causing danger, and increase stability through the cooperation of the limiting sleeve and the support column.

[0019] Example 1
[0020] The utility model provides a supporting structure for a sintering furnace, comprising a base structure, a column structure and a bearing structure.
[0021] A base 12 is mounted on the base 11 , and an airway and a plug hole are provided on the base 12 .
[0022] The bushing 21 has a thread inside, and the bushing 21 is connected to the threaded portion 23 through the threaded thread. The upper end of the threaded portion 23 is connected to the support column 22. The threaded portion 23 and the support column 22 are integrally formed, and the bushing 21 can be inserted into the socket.
[0023] There are four carrier plates 3 , and a limiting sleeve 31 is installed at the lower end of the carrier plate 3 . There are multiple limiting sleeves 31 , and a limiting hole 32 is formed at the lower end of the limiting sleeve 31 . The surface of the limiting hole 32 is an inclined surface.
[0024] Example 2
[0025] When using the utility model, the operator screws the support column 22 into the bushing 21 through the threaded portion 23, covers the carrier plate 3, and the limiting sleeve 31 guides the placement of the carrier plate 3 through the inclined surface of the limiting hole 32. When the placement is inaccurate, the top end of the support column 22 can slide into the limiting hole 32 along the inclined surface of the limiting hole 32, thereby achieving accurate installation and positioning of the carrier plate 3 and increasing its stability.
[0026] When the operator places or removes items on the carrier 3, the limiting sleeve 31 can effectively limit the carrier 3 to prevent it from shifting with the movement of the items. As the device is used, the base 12 collapses due to heat. At this time, the support column 22 needs to be replaced to make the distance between the base 12 and the carrier 3 constant. Remove the carrier 3 to replace the support column 22. Since the surface of the limiting hole 32 is an inclined surface, the support column 22 will not be stuck in it and difficult to remove. Rotate the support column 22 to screw it out of the bushing 21 through the threaded portion 23, screw the replaced support column 22 in, cover the carrier 3, and complete the replacement of the support column 22.

The various components mentioned in the utility model are common technologies in the existing field. The technicians in this industry should understand that the utility model is not limited by the above embodiments.
