Description

Technical Field

[0001] The utility model relates to the technical field of metal powder sintering, in particular to a tungsten powder sintering furnace with an anti-oxidation function. Background Art

[0002] In the field of metal processing and materials science, tungsten powder, as a special metal powder with high melting point, high strength and corrosion resistance, is widely used in many key fields such as aerospace, military industry, and electronic devices. However, the sintering process of tungsten powder is complex and requires extremely high temperature control, which directly affects the performance and quality of the final product.

[0003] During the tungsten powder sintering process, the tungsten powder usually needs to be placed in a sintering furnace and heated to a specified temperature. However, since existing tungsten powder sintering furnaces usually adopt a closed structure, the changes in the tungsten powder cannot be directly observed during the sintering process. Researchers can only infer the sintering progress through indirect means such as temperature curve analysis. This greatly increases the uncertainty of the sintering process and easily leads to uneven sintering of the tungsten powder, affecting product quality.

[0004] Therefore, we want to develop a tungsten powder sintering furnace with anti-oxidation function, which can facilitate tungsten sampling during the sintering process, facilitate the control of the sintering process of tungsten powder, avoid uneven sintering of tungsten powder, and improve the sintering quality of tungsten powder. Utility Model Content

[0005] In order to overcome the shortcomings of existing tungsten powder sintering furnaces that usually adopt a closed structure, which makes it impossible to directly observe the changes of tungsten powder during the sintering process, easily leads to uneven sintering of tungsten powder and affects product quality, the utility model provides a tungsten powder sintering furnace with anti-oxidation function, which can facilitate tungsten sampling during the sintering process, facilitate the control of the sintering process of tungsten powder, avoid uneven sintering of tungsten powder, and improve the sintering quality of tungsten powder.

[0006] The technical solution of the utility model is: a tungsten powder sintering furnace with an anti-oxidation function, comprising a sintering furnace, a track, a heating wire, a closed door, an anti-oxidation component and a sampling component, the bottom of the sintering furnace is connected with the track, the top of the sintering furnace is connected with the heating wire, the front right side of the sintering furnace is rotatably connected with the closed door, the sintering furnace is provided with an anti-oxidation component that can prevent the tungsten powder from being oxidized during the sintering process, and the closed door is provided with a sampling component that is convenient for sampling the tungsten powder.

[0007] In one embodiment, the sealing door is provided with a handle.

[0008] In one embodiment, the anti-oxidation component includes a connecting pipe and a valve. The connecting pipe is connected to the left side of the front of the sintering furnace, and the valve is rotatably connected to the connecting pipe.

[0009] In one embodiment, a data display panel is further included, and the data display panel is connected to the front side of the upper portion of the sealed door.

[0010] In one embodiment, the sampling assembly includes a sampling rack and a cover plate. The sampling rack is slidably connected to the middle of the sealed door, and the cover plate is slidably connected to the sampling rack.

[0011] In one embodiment, a pull block is provided on the sampling rack.

[0012] The beneficial effect is that the utility model places the tungsten powder sample in the sampling rack and sinters it synchronously with the tungsten powder. When sampling is needed, the sliding cover plate takes out the tungsten powder sample on the sampling rack for observation, thereby facilitating the sampling of tungsten during the sintering process, facilitating the control of the sintering process of tungsten powder, avoiding uneven sintering of tungsten powder, and improving the sintering quality of tungsten powder.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0018] A tungsten powder sintering furnace with anti-oxidation function, such as Figure 1-Figure 3 As shown, it includes a sintering furnace 1, a track 2, a heating wire 3, a sealed door 6, a connecting pipe 4, a valve 5, a data display board 7, a sampling rack 8 and a cover plate 9. The bottom of the sintering furnace 1 is connected to the track 2, the top of the sintering furnace 1 is connected to the heating wire 3, the front right side of the sintering furnace 1 is rotatably connected to the sealed door 6, and the sealed door 6 is provided with a handle for easy opening. The left front part of the sintering furnace 1 is connected to the connecting pipe 4, and the connecting pipe 4 is rotatably connected to the valve 5.

[0019] When using the present invention, first place the device in the tungsten powder sintering area, then rotate and open the sealed door 6, place the tungsten powder to be sintered on the sintering car, and then push the sintering car from the track 2 into the sintering furnace 1, then rotate the sealed door 6 and the sintering furnace 1 to close, and start the heating wire 3 to heat the sintering furnace 1 to increase the temperature, thereby sintering the tungsten powder. When heating and sintering the tungsten powder, rotate and open the valve 5, extract the air in the sintering furnace 1 through the connecting pipe 4, and introduce inert gas into the sintering furnace 1 from the connecting pipe 4 to prevent the tungsten powder from contacting with the air at high temperature and oxidizing. The temperature in the sintering furnace 1 and the sintering time of the tungsten powder are observed through the data display panel 7 to facilitate the control of the sintering process of the tungsten powder. Before sintering, slide the cover plate 9 upwards, slide the sampling rack 8 out of the sintering furnace 1, place the tungsten powder sample on the sampling rack 8, and then slide the sampling rack 8 into the sintering furnace 1, and then slide the cover plate 9 to cover the sampling rack 8, and then start the heating wire 3 to heat and sinter the tungsten powder sample and the tungsten powder in the sintering car simultaneously. During the sintering process, the cover plate 9 can be slid open, the sampling rack 8 can be slid out, and the tungsten powder sample on the sampling rack 8 can be observed to judge the completion degree of the sintered tungsten powder, thereby facilitating the control of the sintering process of the tungsten powder, thereby facilitating the sampling of tungsten during the sintering process, facilitating the control of the sintering process of the tungsten powder, avoiding uneven sintering of the tungsten powder, and improving the sintering quality of the tungsten powder.
