Description

Technical Field

[0001] The invention relates to a dust control system and an operating method for hot processing of space metal materials, belonging to the technical field of redundant object protection control in space environment. Background Art

[0002] During this period, the space station will continue to be tested by the space environment, especially the impact of space debris. Although the outer side of the space station cabin structure adopts a protective structure, there is still a risk of damage by impact, and there is a need for in-orbit repair of the metal structure cabin.

[0003] As space vehicles and space structures become increasingly larger, in-orbit in-situ construction has become a technical challenge that urgently needs to be solved. Space metal connection and additive manufacturing are the necessary means for in-orbit in-situ construction of large structures.

[0004] Electron beams have the advantages of high energy utilization, high equipment reliability, and good adaptability to vacuum environments, and are considered to be the most suitable space heat source for on-orbit manufacturing. The weightless transition of metal droplets in the space environment, the instability of the molten pool, the separation and solidification of the molten pool during cutting, and the control mechanism of interlayer bonding are quite different from those in the ground gravity environment, and it is difficult for simulation to fully simulate the actual on-orbit working conditions. At present, the space station's extravehicular test environment can be used to carry out experimental verification of electron beam on-orbit manufacturing technology and optimize the multifunctional electron beam thermal processing process technology. However, the conduction of space electron beam thermal processing experiments will produce excess materials such as metal vapor, which will cause safety hazards if leaked outside or inside the cabin.

[0005] In order to eliminate the potential safety hazard of excess materials generated by space electron beam thermal processing experiments contaminating equipment inside or outside the cabin, it is necessary to propose a space metal material thermal processing dust control system to protect the excess materials generated by the metal hot processing experiment from leaking out of the test device during the entire process from the start of the test to the return to the earth.

The front panel is designed with grooves and openings for installing the sealed storage part and removing the test piece. The remaining panels provide installation interfaces for other single machines and mechanisms for hot working.

[0082] The test box 1 is formed by splicing six frame panels at the front, rear, left, right, top and bottom. Sealing gaskets are installed on the fitting surfaces of each panel to ensure the sealing of each splicing point.

[0083] The front panel is designed with grooves and openings for installing the seal 2, the specimen storage bag 4 and the end cover 3.

[0084] The sealing storage part is composed of a sealing member 2, an end cover 3 and a specimen storage bag 4, etc. Its main function is to block the specimen removal channel on the test box to prevent thermal processing dust from leaking out of the test box. Figure 6 shown.

[0086] The size of the specimen storage bag 4 is designed according to the maximum outer envelope and operating space of the hot-processed specimen, ensuring that the specimen can be completely placed in the bag and leaving an operating margin for two seals.

[0087] The end cover 3 and the sealing member 2 solidify the assembly state of the specimen storage bag 4, ensuring that the storage bag will not fall out of the assembly position when the pressure difference between the inside and outside of the test box changes.

[0088] The specimen part is composed of an unlocking component 6, a specimen 7, a locking column 8, a locking column spring 9, a specimen box 10, a first spring component 11, a locking component 12, a limiting component 13 and a second spring component 14.

Its main function is to serve as a channel connecting the inside and outside of the test chamber to achieve gas medium exchange. It ensures that in the process of achieving internal and external pressure balance, the excess in the test chamber will not leak into the cabin or space. The position of filter 5 can be adjusted according to the layout of the interior of different test chambers.

[0098] The working steps of the entire hot processing dust control method are as follows:

[0099] Step 1: After the heat treatment of the specimen 7 is completed, the XY motion mechanism 26 moves the specimen part 15 to the unlocking position, triggering the unlocking assembly 6, the specimen 7 is unlocked, popped out of the specimen box 10, and the specimen storage bag 4 is pushed to contact the end cover 3;

[0100] Step 2: Remove the end cover 3, and the test piece 7 is ejected from the test piece box 10 by the spring assembly for a certain distance, protruding out of the outer surface of the test box; Figure 4 As shown;

[0101] Step 3, manually take out the test piece 7 from the test piece storage bag 4, and seal the test piece storage bag 4 at two places with a cable tie, and then cut it between the two places; Figure 5 As shown;
