Device for maintaining pressure balance between inside and outside of glovebox during metal 3D printing

Abstract

A glovebox is needed for operating during metal 3D printing. But how to guarantee that pressure balance between inside and outside of a glovebox during the use of the glovebox is maintained is crucial for guaranteeing whether a metal part can be successfully formed or not, otherwise breakage of a glove may be caused, thereby influencing the printing forming process of a metal part. So, a device for maintaining pressure balance between inside and outside of a glovebox during metal 3D printing is one of core devices used during metal 3D printing forming. The present invention provides a device for maintaining pressure balance between inside and outside of a glovebox during metal 3D printing. The device comprises a vacuum box for metal part forming, and a glovebox in which gloves are placed, as well as the following units located within the glovebox: two one-way valves connecting the glovebox with the vacuum box; two metal elongated cylinders for actuating the two one-way valves. The device can maintain pressure balance between inside and outside of a glovebox during metal 3D printing, thereby allowing for normal and safe use of the glovebox.

Description

technical field [0001] The invention relates to a device, in particular to a device for maintaining pressure balance inside and outside a glove box during metal 3D printing. Background technique [0002] The metal 3D printing process needs to be operated with a glove box, but how to maintain the pressure balance inside and outside the glove box during the use of the glove box is the key to ensure the smooth formation of metal parts, otherwise it will cause the gloves to break and affect the printing of metal parts process. Therefore, the device that maintains the pressure balance inside and outside the glove box during the metal 3D printing process is one of the core devices in the metal 3D printing process.
