Problems solved by technology

[0004] However, the current research on the 3D printing process of continuous fiber reinforced composite materials is still in its infancy, and there are still some technical difficulties. To realize it with a device, not only the motion structure is huge, but also complex motion control algorithms are required, which greatly limits the molding speed of continuous fiber composite 3D printing

Abstract

The invention discloses a 3D printing head and a using method of continuous fiber reinforced materials, which relate to the technical field of fused deposition, and include a base frame, a feeding mechanism, a printing nozzle and a shearing mechanism arranged on the base frame, wherein the The printing nozzle includes a throat, a heating pipe and a nozzle, the throat has a first cavity along the length direction, the nozzle is connected to the lower end of the throat, and the heating pipe is sleeved between the throat and the nozzle. The outer wall of the nozzle, the first cavity communicates with the nozzle outlet of the nozzle, the shearing mechanism includes a power part and a pendulum ball, and the pendulum ball is arranged between the first cavity and the Between the outlets of the nozzles and the pendulum ball has a second cavity communicated with the first cavity, one end of the power element is connected to the pendulum ball, and the other end is connected to the base frame; The power part is used to drive the pendulum ball to rotate at a certain angle, so that the pendulum ball switches between the first working state and the second working state.

Description

technical field [0001] The invention relates to the field of fused deposition technology, in particular to a 3D printing head for continuous fiber reinforced materials and a method for using it Background technique [0002] Continuous fiber composites have excellent properties such as high modulus, high strength, low specific gravity, and wear resistance, and have important application prospects in aerospace, national defense and military industries, and civil industries. Traditional continuous fiber composite molding processes include thermocompression molding, RTM molding, winding molding, pultrusion molding, lamination molding, etc., which have played a very important role in promoting the development and application of continuous fiber composite materials, but there have always been some The disadvantages cannot be overcome. For example, most molding processes require special molds. The molding process is complicated and the processing cost is high. It is difficult to ac...
