Abstract

The invention relates to the technical field of 3D printing equipment, in particular to a quantitative powder supply device for metal 3D printing. The quantitative powder supply device comprises a seat body, a stepping motor, an encoder, a controllable groove type batcher, a connecting shaft and a controller, the top end and the bottom end of the seat body are correspondingly provided with a feedport and a discharge port, and the controllable groove type batcher is coaxially and rotatably arranged in the seat body; the connecting shaft is coaxially arranged at one end of the controllable groove type batcher, the driving end of the controllable groove type batcher is coaxially and fixedly connected with the connecting shaft, the encoder is arranged above the stepping motor, in the workingstate, the encoder is used for calculating the rotating angle of the stepping motor in real time, and the stepping motor and the encoder are both electrically connected with the controller. The devicequantitatively conveys powder through the controllable groove type batcher and is easy to operate.

Description

technical field [0001] The invention relates to the technical field of 3D printing equipment, in particular to a quantitative powder supply device for metal 3D printing. Background technique [0002] With the development of science and technology, metal 3D printing technology has become more mature, and its printing methods have become more diversified, among which laser selective melting is the most common application. The principle of laser selective melting technology is: the metal powder in the laser melting selected area is accumulated layer by layer to form the target sample. It can be seen that in the metal 3D printing laser melting selection technology, the powder supply device is very critical, and it is necessary to realize the effect of timely powder supply and quantitative powder supply. [0003] There is an urgent need in the market for a quantitative powder supply switch that can operate stably, is suitable for powders with a large particle size range, and has...
