Additive equipment and additive method

Abstract

The invention provides a material additive equipment and a material additive method, and relates to the technical field of solid phase additive materials. The additive equipment includes a feeding device, a stirring device and mounting parts. The feeding device includes a feeding box and an extruder, and the discharge end of the feeding box communicates with the feeding end of the extruder. The discharge end of the extruder and the stirring end of the stirring device are arranged at intervals. Both the feeding box and the stirring device are connected to the mounting parts and move with the movement of the mounting parts, so that the materials extruded by the extruder are rubbed by the stirring device. After pressing, an additive layer is formed. The additive equipment can realize the automatic process of friction stir additive and increase the efficiency of friction stir additive. The additive method adopts the above additive equipment mainly according to the following steps: the material is fed from the feeding box to the extruder, and the material extruded by the extruder is rubbed and rolled by the stirring device. The method has the advantages of wide application range of materials, high efficiency, excellent structure and performance of the additive layer, high efficiency, green and pollution-free, small deformation, etc., and the final additive layer has small deformation.

Description

technical field [0001] The present invention relates to the technical field of solid-phase additives, in particular to an additive equipment and an additive method. Background technique [0002] Additive manufacturing is a technology that uses the method of gradually accumulating materials to manufacture solid parts. Compared with the traditional material removal-cutting technology, it is a "bottom-up" manufacturing method. [0003] Traditional additive manufacturing methods include laser additive, arc additive, plasma additive, etc., which have been widely used in aerospace. However, the traditional additive methods are all melting additives, which have disadvantages such as large deformation and low additive efficiency. Contents of the invention [0004] One of the objectives of the present invention includes providing an additive equipment, which can realize the automatic process of friction stir additive and increase the efficiency of friction stir additive.
