Description

Technical Field

[0001] The present invention relates to the technical field of material preparation, and particularly to a high-throughput alloy sintering device. Background Art

[0002] In the field of modern materials science, the research and production of alloy materials play a crucial role. As the core link among them, the sintering process plays a decisive role in the final properties of alloy materials.

[0003] Facing the increasing demand for material research and development, traditional alloy sintering devices have gradually revealed many limitations. In terms of sample preparation, the number of sintered samples is extremely limited, unable to meet the requirements of large-scale and high-throughput preparation. This makes it difficult to obtain a sufficient number of diverse samples for comprehensive research in a short time when exploring new alloy materials. In terms of process parameter regulation, the lack of flexibility leads to the inability to quickly and accurately change various parameters during the sintering process, such as temperature, pressure, atmosphere, etc., seriously restricting the in-depth exploration of alloy properties under different process conditions. In terms of the precision of raw material powder mixing, traditional devices are difficult to achieve high-precision powder mixing operations, easily causing deviations in alloy composition, thereby affecting the performance consistency and stability of alloy materials. In addition, the inconvenience of data collection and analysis also makes it extremely difficult to monitor the sintering process in real time and conduct subsequent evaluations, and it is impossible to provide timely and accurate data support for the optimization of alloy materials.

[0004] With the rapid development of technology and the continuous in-depth research of materials science, the demand for exploring new alloy materials is becoming increasingly urgent. In many industries such as aerospace, automotive manufacturing, and electronic information, the expectation for high-performance alloy materials prompts the R & D work to quickly and efficiently prepare a large number of alloy samples with different compositions and different process parameters. Only through the screening and analysis of numerous samples is it possible to discover alloy materials with excellent properties to meet the ever-increasing requirements of various industries for material performance. This current situation urgently requires innovative improvements to traditional alloy sintering devices to adapt to the efficient and precise needs of modern material research and development.

[0055] To facilitate the understanding of the technical solution of the present invention, the process of material preparation of the above-mentioned high-throughput sintering equipment is described here:

[0056] When in use, different metal powders are added into the four-way powder feeder 1. The computer control system 13 accurately controls the powder feeding speed and flow rate of each powder feeder 1 according to the input target alloy composition ratio information, and sends the raw materials to be mixed into the mixing chamber 3 through the first powder feeding pipe 2, so as to realize powder blending in proportion.

[0057] The powder in the mixing chamber 3 drives the stirring shaft 32 through the stirring motor 31 installed in the mixing chamber 3, so that the stirring shaft 32 drives the stirring roller 33 to rotate. At the same time, the vibration motor 34 installed in the mixing chamber 3 drives the vibration motor transmission shaft 35, so as to vibrate and stir the powder conveyed in the mixing chamber 3 to make the powder fully mixed and uniform.

[0058] After the powder mixing is completed, the uniformly mixed metal powder in the mixing chamber 3 is sent into the screw feeding device 10 through the second powder feeding pipe 4. The telescopic rod 5 extends, and the screw feeding device 10 is sent into the sintering chamber 9.

[0059] At the same time, the computer control system 13 accurately adjusts the moving distance and rotation angle of the first slide rod 15, the second slide rod 16, the telescopic rod 5, the rotating shaft 51 and the rotating shaft 52. Through this all-round and refined control, the screw feeding device 10 can realize precise positioning and movement in three-dimensional space, so as to ensure that the powder can be accurately pushed into each sintering mold 11.

[0060] After the spiral feeding device 10 moves to the corresponding position, the rotating motor 101 installed on the spiral feeding device 10 drives the conveying shaft 102, so that the conveying shaft 102 drives the spiral plate 103 to rotate. Under the rotational pushing action of the spiral plate 103, the powder is stably conveyed into the sintering mold 11. At the same time, the computer control system 13 precisely controls the pushing amount and pushing speed of the powder, so that the powder amount and powder composition ratio in each sintering mold 11 can be effectively controlled and guaranteed;

[0061] After the powder feeding is completed, the spiral feeding device 10 rises to the designated area above the sintering chamber 9 under the precise control of the computer control system 13. After the sintering chamber 9 is completely sealed, the computer control system 13 can precisely control the atmosphere type of the atmosphere control system 14, such as inert gases (argon, nitrogen, etc.), reducing gases (hydrogen, etc.) or oxidizing gases (oxygen, etc.), so that the sintering chamber 9 can switch the atmosphere environment in real time according to different process requirements during the sintering process.

The accuracy of the atmosphere flow rate control can reach ±0.1 L / min, and the sintering chamber 9 can be evacuated to 0.1 Pa;

Each heating unit 91 can be independently temperature-controlled, which can make the heat evenly and efficiently diffuse in the chamber, avoid abnormal local temperature differences, and ensure that the samples in each sintering mold 11 are heated evenly. The computer control system 13 precisely monitors the temperature change in real time through the temperature sensor 92 and flexibly and precisely controls the sintering temperature according to the feedback information. The temperature range is between 500 °C and 2000 °C to meet the requirements of various alloy systems.

[0064] After the sintering is completed, the sample is cooled to room temperature, and then the power supply of each part is turned off to end the experimental process.

[0065] Through the high-throughput alloy sintering equipment of the present invention, a large number of alloy samples with different compositions and process parameters can be processed simultaneously in a single sintering experiment, greatly improving the R & D efficiency of alloy materials, shortening the R & D cycle, and with the precise automatic powder feeding module and advanced control system, it can accurately control various parameters during the sintering process, providing strong technical support for the development of high-performance alloy materials.
