Abstract

A metal 3D printer air inlet and outlet structure with stable airflow is used to be installed on the metal 3D printer equipment, including an air inlet and an air outlet. The air enters from the air inlet and is discharged from the air outlet. The air outlet part includes an air outlet, an air outlet channel and an air outlet connection port, and the air outlet port communicates with the air outlet connection port through the air outlet channel; the air inlet part includes an upper air inlet, a lower air inlet, an air inlet The air passage and the air inlet connection port, the upper and lower air inlets communicate with the connection port through the air inlet passage; the air outlet, the upper and lower air inlets are all square, and the flow rate of the upper air inlet is less than the The flow of the lower air inlet, the total flow of the upper and lower air inlets is less than the flow of the air outlet. In the present invention, upper and lower air inlets are arranged on the air inlet, and one air inlet is changed to two air inlets, and the flow rate of the air outlet is greater than the flow rate of the upper and lower air inlets, so that the air inlet and outlet of the metal 3D printer The airflow of the structure is stable.

Description

technical field [0001] The invention relates to the technical field of the air inlet and outlet structure of a 3D printer, in particular to a metal 3D printer air inlet and outlet structure with a smooth airflow. Background technique [0002] Metal 3D printing is an emerging technology that is rapidly developing in the manufacturing field, especially in developed countries in Europe and America, there are already many types of metal 3D printers. Metal 3D printing is a kind of additive manufacturing technology. It is based on digital model files, sintering metal powder by laser, and printing three-dimensional objects layer by layer. Therefore, it is necessary to arrange a wind guide and heat dissipation device for cooling down. However, the air inlet and outlet structures of existing printers usually have disadvantages such as complex structure, difficult disassembly, and large loss of gas in the circulation flow. [0003] The Chinese patent application number is 2016103330...
