Spatial multi-degree-of-freedom additive manufacturing equipment based on continuous fiber reinforcement

Abstract

The invention discloses spatial multi-degree-of-freedom additive manufacturing equipment capable of realizing continuous fiber reinforcement manufacture, and a continuous fiber reinforcement technology is introduced to the field of additive manufacture. The spatial multi-degree-of-freedom additive manufacturing equipment is composed of five parts in total: a base, a turntable, a vertical shaft anda feeding and molding unit; a mobile unit is designed on the base and is combined with the vertical shaft to change a spatial position for a printing head; the turntable is used for changing a spatial posture for a material plate for processing a workpiece; due to the change of relative positions of the printing head and a workbench, spatial multidirectional fiber laying can be realized; the feeding and molding unit comprises the printing head, a wire feeding mechanism and a scroll; and additive manufacture is realized by using a fused deposition technology. Continuous fibers in a spatial multi-dimensional direction can be laid in an additive manufacture process according to the requirements for performances such as appearances and mechanics of parts, and meanwhile, various base materialsare laid, so that all performances of the parts are enhanced.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a spatial multi-degree-of-freedom additive manufacturing equipment based on continuous fiber reinforcement. Background technique [0002] Additive manufacturing technology has become a hot direction in recent years. It adopts the principle of discrete stacking and becomes a new type of manufacturing method. Compared with traditional subtractive manufacturing and equal material manufacturing, additive manufacturing has the characteristics of rapid prototyping and easy realization of complex configuration parts. [0003] Fusion accumulation technology is a kind of additive manufacturing technology, which melts hot-melt materials, extrudes them through small nozzles, and accumulates them into shapes. Fast forming, simple manufacturing, and relatively high-precision complex configuration parts can be manufactured. However, it is limited by the material, most of whic...
