Abstract

This application discloses a high-temperature alloy powder recycling fixture for additive manufacturing, belonging to the field of high-temperature alloy powder recycling technology for additive manufacturing. The fixture includes a recycling mechanism. A screen is placed inside a mounting plate, and a connecting block at the bottom of a fixed plate is inserted into a connecting hole inside the mounting plate, thus fixing the screen inside the recycling tank. Alloy powder is placed above the screen. A servo motor drives a connecting rod to rotate, which in turn drives a pushing block to push the bottom of the recycling tank. This causes the recycling tank to be under force, causing a moving rod to slide inside the fixed plate. The recycling tank stretches a spring at its bottom, causing the tank to oscillate back and forth. The screen then filters the alloy powder, removing impurities and ensuring the purity of the powder, thus facilitating its recycling. The fixture is simple, quick, and easy to use.

Description

Technical Field

[0001] This application relates to the field of additive manufacturing high-temperature alloy powder recycling technology, specifically an additive manufacturing high-temperature alloy powder recycling tooling. Background Technology

[0002] High-temperature alloys are typically based on iron, cobalt, and nickel, with the addition of numerous alloying elements to achieve excellent high-temperature mechanical properties. Therefore, they are widely used in the manufacture of hot-section components for aero-engines. Based on forming processes, high-temperature alloys can be divided into wrought high-temperature alloys, cast high-temperature alloys, and powder metallurgy high-temperature alloys. Powder metallurgy high-temperature alloys mainly refer to high-temperature alloys produced through powder metallurgy processes. They possess advantages such as uniform microstructure, fine grains, and no macroscopic segregation, and are widely used in additive manufacturing and other fields. Currently, the main manufacturing methods for powder metallurgy high-temperature alloys are gas atomization powder production and plasma rotating electrode powder production. Among these technologies, gas atomization powder preparation has become the most widely used powder preparation technology due to its advantages such as high production efficiency, low production cost, and controllable powder particle size. Additive manufacturing technology has particle size requirements for the required powder raw materials: the required powder particle size range for laser melting forming technology is (15-53) μm. Excessively large powder size will lead to incomplete powder melting during laser scanning, resulting in metallurgical defects in the printed parts; the required powder particle size range for electron beam selective melting technology is (60-150) μm. In addition, there are requirements for powder composition, morphology, and flowability. Currently, the overall powder yield of gas atomization powder preparation in China is generally no more than 50%. With the continuous development of additive manufacturing technology, the amount of waste powder obtained in the production process is increasing, resulting in huge resource waste. For waste powder with the required composition, it can be used as raw material for secondary remelting and powder spraying, realizing the reuse of resources.

[0003] Existing alloy powder recycling equipment mainly collects alloy powder together, but the alloy powder contains impurities, so it still needs to be screened afterward. The operation steps are cumbersome and inconvenient to use.

[0004] Therefore, this application provides a tooling for recycling high-temperature alloy powder from additive manufacturing to solve the above problems. Utility Model Content

[0005] This application provides a high-temperature alloy powder recycling tooling for additive manufacturing, which aims to solve the problems of existing alloy powder recycling tooling in the background art, which collect alloy powder together, but the alloy powder contains impurities and still needs to be screened afterward, making the operation steps cumbersome and inconvenient to use.

[0006] To achieve the above objectives, this application provides the following technical solution: a tooling for recycling high-temperature alloy powder from additive manufacturing, the tooling including a recycling mechanism;

[0007] Preferably, to address the problem that existing alloy powder recycling fixtures often collect alloy powder together, but the powder contains impurities and still requires subsequent sieving, resulting in cumbersome and inconvenient operation, the recycling mechanism includes a base. A fixed rod is fixedly connected to the top of the base. A movable rod is located inside the fixed rod, and a recycling trough is located at the top of the movable rod. An installation plate is located inside the recycling trough, and a fixed plate is located at the top of the installation plate. A screen is installed between the slots on opposite sides of the installation plate and the fixed plate. The installation plate is mounted on top of the installation block, and the screen is placed inside the installation plate. The screen is connected to the fixed plate via a connecting block at the bottom. The mounting plate has internal insertion holes for attaching the screen, allowing it to be fixedly installed inside the recycling tank. Alloy powder is placed on top of the screen. Activating the servo motor rotates the connecting rod, which in turn pushes the bottom of the recycling tank against a push block. This force causes the recycling tank to slide within the fixed plate, pulling a spring at the bottom. The spring causes the recycling tank to oscillate back and forth, sieving the alloy powder through the screen. This process facilitates the removal of impurities from the alloy powder, ensuring its purity and making it easy to recycle. The operation is simple, quick, and convenient.

[0008] Preferably, to address the issue of easy movement of the recycling bin, a servo motor is fixedly connected to one side of the base, a connecting rod is fixedly connected to the output end of the servo motor, and a pushing block is fixedly connected to the outside of the connecting rod. The pushing block is located at the bottom of the recycling bin. The servo motor drives the connecting rod to rotate, and the pushing block outside the connecting rod pushes the recycling bin, thereby facilitating the shaking of the recycling bin and making it convenient to use.

[0009] Preferably, to solve the problem of reciprocating movement of the recycling trough, the moving rod is slidably connected to the fixed rod, and a spring is fixedly connected between the top of the base and the outside of the recycling trough. The spring is set outside the fixed rod and the moving rod. The recycling trough drives the moving rod to slide inside the fixed rod, and the recycling trough stretches the spring. Through the spring, the recycling trough can reciprocate, which is convenient to use.

[0010] Preferably, in order to solve the problem of easy installation of the mounting plate, an mounting block is fixedly connected to the inner wall of the recycling tank. The mounting block is inserted into the mounting plate. By inserting the mounting plate into the mounting block, the mounting plate can be easily installed and fixed inside the recycling tank.

[0011] Preferably, in order to solve the problem of easy installation and disassembly of the screen, a plug-in block is fixedly connected to the bottom of the fixing plate, and a plug-in hole is opened inside the mounting plate. The plug-in block is adapted to the plug-in hole, and the plug-in hole is plugged into the plug-in block, and the plug-in block is plugged into the plug-in hole. This can easily fix the screen inside the mounting plate and the fixing plate, thereby facilitating installation and disassembly.

[0012] Preferably, in order to solve the problem of convenient use of the recycling tank, a sealing groove is fixedly connected to both sides of the recycling tank, and a sealing plate is provided inside the sealing groove. The sealing plate is slidably connected to the sealing groove, and the sealing groove is slidably connected to the sealing plate, which can facilitate the discharge of the sieved alloy powder into the interior of the recycling tank, making it convenient to use.

[0013] This recycling mechanism mounts a mounting plate on top of a mounting block, places a screen inside the mounting plate, and secures the screen inside the recycling tank by inserting a connecting block at the bottom of the mounting plate into a connecting hole inside the mounting plate. Alloy powder is placed above the screen. Activating the servo motor rotates the connecting rod, which in turn pushes a push block against the bottom of the recycling tank. This force causes the moving rod to slide inside the mounting plate, stretching a spring at the bottom of the recycling tank. The spring causes the tank to oscillate back and forth, allowing the screen to sieve the alloy powder. This sieving process removes impurities from the alloy powder, ensuring its purity and facilitating recycling. The operation is simple, quick, and convenient. Attached Figure Description
