Continuous feeding, stirring and friction additive manufacturing device and additive manufacturing method thereof

Abstract

The invention provides a continuous feeding, stirring and friction additive manufacturing device and an additive manufacturing method thereof. The device comprises a hydraulic ejector rod mechanism, a disc type feeding mechanism, an upper clutch module, a lower clutch module, a constant-speed feeding mechanism, an additive stirring head and an additive manufacturing component which are arranged from top to bottom; a plurality of additive raw materials are evenly arranged in the disc type feeding mechanism, the disc type feeding mechanism replaces the next additive raw material under the condition that the disc type feeding mechanism does not stop rotating, the two clutch modules are matched to guide the new additive raw material and the previous additive raw material to be introduced into the additive stirring head in a phase synchronization mode, and the hydraulic ejector rod mechanism pushes the new additive raw material to be introduced into the upper clutch module; and the constant-speed feeding mechanism drives the additive raw materials to move downwards, and the stirring head drives the additive raw materials to rotate and perform friction thermal plasticizing deposition with the additive manufacturing component, so that continuous feeding additive manufacturing is achieved. The device breaks through the current situations that continuous feeding of traditional stirring friction material increase is difficult, layer-by-layer clamping is needed, defects are prone to being generated, and secondary machining is needed after material increase, and solves the problem that interruption restarting is difficult.

Description

technical field [0001] The invention belongs to the technical field of solid-phase additive manufacturing, and in particular relates to a continuous feeding and feeding friction stirring additive manufacturing device and an additive manufacturing method. Background technique [0002] Additive manufacturing technology, commonly known as 3D printing technology, is a digital manufacturing technology that achieves moldless and precise forming of components by adding and accumulating materials layer by layer. It manufactures three-dimensional complex shape components into simple two-dimensional planar shapes. It avoids a large amount of material and energy waste in traditional machining and precise forming manufacturing, and provides a new design idea for the realization of high-performance or super-performance key components. At the same time, this technology can greatly shorten the production cycle, reduce production costs and processing and manufacturing costs, making it possi...
