Protective gas device with reminding function for 3D printing

Abstract

The invention provides a protective gas device with a reminding function for 3D printing, and belongs to the technical field of protective gas devices for 3D printers, the protective gas device comprises a pair of circular guide columns with two through ends, the adjacent ends of the pair of circular guide columns with two through ends are fixedly connected with one end of a connecting opening, and a circular opening is reserved in a square frame; hoop sleeves are hooped on the peripheral surfaces of the pair of connecting openings, and clamping assemblies are arranged in the edges of the square frame. In the prior art, a protective gas device used as a protective gas system comprises a gas cylinder, pressure reducing equipment, steel pipes and the like, the pressure reducing equipment is an argon pressure reducing valve or a pressure regulating valve, protective gas overflows at the joints between the gas cylinder and the steel pipes, between the pressure reducing equipment and the steel pipes and between the steel pipes, and workers cannot be informed to process the protective gas; and if the treatment is too slow, the loss of the protective gas is caused, the concentration of the indoor protective gas is increased, and if the concentration is too high, the breathing discomfort of workers is caused.

Description

Technical field: [0001] The invention belongs to the technical field of protective gas devices for 3D printers, and in particular relates to a protective gas device for 3D printing with a reminder function. Background technique: [0002] 3D printing technology appeared in the mid-1990s and is actually the latest rapid prototyping device utilizing technologies such as light curing and paper lamination. The working principle of it is basically the same as that of ordinary printing. The printer is filled with "printing materials" such as liquid or powder. After connecting to the computer, the "printing materials" are superimposed layer by layer through computer control, and finally the blueprint on the computer is turned into a real object. The shielding gas system is an important part of SLM molding in 3D printing technology. The protective gas device as the protective gas system includes gas cylinders, decompression equipment and steel pipes, etc. The decompression equipment...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a protective gas device with reminding function for 3D printing, the purpose of which is to solve the problem of overflow of protective gas at the joints between gas cylinders and steel pipes, decompression equipment and steel pipes, and steel pipes in the prior art The situation cannot be informed to the staff to deal with it. If the treatment is too slow, the protective gas will be lost, and the concentration of the indoor protective gas will also increase. If the concentration is too high, the staff will suffer from breathing discomfort.
