Abstract

The invention provides an airflow-smooth air inlet / outlet structure for a metal 3D printer, and the airflow-smooth air inlet / outlet structure is used for metal 3D printer equipment. The airflow-smooth air inlet / outlet structure comprises an air inlet piece and an air outlet piece. The airflow enters the structure from the air inlet piece and is discharged from the air outlet piece. The air outlet piece comprises an air outlet, an air outlet channel and an air outlet joint. The air outlet communicates with the air outlet joint through the air outlet channel. The air inlet piece comprises an upper air inlet, a lower air inlet, an air inlet channel and an air inlet joint. The upper air inlet and the lower air inlet communicate with the corresponding joint through the air inlet channel. Each of the air outlet, the upper air inlet and the lower air inlet is square. The flow of the upper air inlet is smaller than that of the lower air inlet. The total flow of the upper air inlet and the lower air inlet is smaller than the flow of the air outlet. According to the airflow-smooth air inlet / outlet structure for the metal 3D printer, the upper air inlet and the lower air inlet are formed in the air inlet piece, one-way air inlet is changed into two-way air inlet, the flow of the air outlet is larger than the total flow of the upper air inlet and the lower air inlet, and thus the airflow of the air inlet / outlet structure for the metal 3D printer is smooth.

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...
