Description

Additive manufacturing mechanism suitable for continuous fiber reinforced composites of different sizes
TECHNICAL FIELD
The present invention relates to the field of additive manufacturing technology, and in particular, to an additive manufacturing mechanism suitable for continuous fiber reinforced composites of different sizes.
BACKGROUND
Additive manufacturing for continuous fiber reinforced composites is also referred to as 3D printing manufacturing, is different from conventional subtractive or equivalent manufacturing methods, and manufactures physical parts by layer-by-layer accumulation of materials. Its working principle is to discretize a three-dimensional computer model of a physical entity into a series of two-dimensional lamellae and superimpose and cure cladding forming materials through continuous physical layers using a precision nozzle or laser heat source according to lamella information under the drive of digital control, to generate three-dimensional physical products. Continuous fiber reinforced composites have the characteristics of high strength, high modulus, small specific gravity, good thermal stability, strong designability, and the like. Their excellent comprehensive performance is exactly what aerospace, national defense, and military products need to pursue maximum structural quality and efficiency.
Existing additive manufacturing devices for continuous fiber reinforced composites use a straight or oblique shear blade as a laying head. The straight shear blade has a large shear force and easily produces a large tensile force on a continuous fiber reinforced composite during shearing, making it difficult to cut off the continuous fiber reinforced composite. The oblique shear blade enables wrinkles or sliding out of a guide groove due to extrusion deformation of a continuous fiber reinforced composite, leading to a low overall cut-off rate of the continuous fiber reinforced composite.
Therefore, an additive manufacturing mechanism suitable for continuous fiber reinforced composites of different sizes is urgently needed to solve the above problems.

The continuous fiber reinforced composite passes through the ring blade body and is cut off by driving the plurality of blades to extend and retract. Since four sides of the continuous fiber reinforced composite are limited by the blades, the continuous fiber reinforced composite will not slide horizontally and its incision will not have significant deformation. Further, as the blades extend from an inner side of the ring cutter body towards a center during cutting, the continuous fiber reinforced composite is caught in the central channel of the ring cutter body and comes into contact with the blades, the continuous fiber reinforced composite slides in an extension direction of the blades, so that the continuous fiber reinforced composite is cut off more easily.
