Problems solved by technology

The advantage of this material conveying device is that it works smoothly and can quantitatively control the amount of material conveyed. The disadvantage is that it needs to add a sufficient amount of material to the powder box at one time, and it cannot be supplemented during work, which results in a large space for the entire equipment and increases the cost of the whole machine.

Abstract

A material conveying system and its control method, and additive manufacturing equipment, wherein the material conveying system includes a material conveying pipe and a closed material storage tank, and the conveying pipe is sequentially provided with a discharge end, a first groove, a second Groove and feeding end, there is a movable first plugging ball on the first tank and a movable second plugging ball on the second tank in the feeding pipe, and the top of the feeding pipe is provided with a piston rod , the feeding pipe is located between the first tank and the second tank and is provided with a branch pipe connected with the feeding pipe, and the end of the branch pipe far away from the feeding pipe is provided with a push rod, and the feeding end is connected with the storage The cylinders are connected, and at least one gas inlet is provided on the storage cylinder. The material conveying system and its control method, and the additive manufacturing equipment of the present invention control the amount of material conveyed each time by controlling the moving distance of the push rod in the branch pipe, and the control method is not only simple, but also more accurate.

Description

technical field [0001] The present application relates to the technical field of additive manufacturing, in particular to a material conveying system and its control method, and additive manufacturing equipment. Background technique [0002] Additive Manufacturing technology (Additive Manufacturing, referred to as AM) is an advanced manufacturing technology with distinctive features such as digital manufacturing, high flexibility and adaptability, direct CAD model drive, fast speed, and rich and diverse material types. The degree of limitation does not require any tooling and molds, so the application range is very wide. As one of the additive manufacturing technologies, Selective Laser Melting (SLM for short) has developed very rapidly in recent years. Its main process is: the material conveying device sends a certain amount of material to the work surface, and the powder spreading device will A layer of material material is spread on the upper surface of the formed part o...
