Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of carbon fiber reinforced resin-based composite component manufacturing technology, especially a kind of carbon fiber reinforced resin-based composite material additive manufacturing technology, specifically a kind of double-spindle mirror image horizontal automatic placement device. BACKGROUND

[0002] Carbon fiber reinforced resin-based composite material (CFRP) has light weight, high strength, toughness, impact resistance and other excellent performance, is the preferred material of high-end equipment performance leapfrogging in aerospace field.

[0003] At present, there are a large number of composite material components in aerospace field, such as inlet, rocket barrel section, fuselage cabin section, including flat plate and curved surface parts. Using traditional mold on the wrapping integrated manufacturing method, it is difficult to combine and demold, and the mold cost is high, the cycle is long, which seriously restricts the efficient development and high-quality manufacturing of components.

[0004] In view of the above problems, moldless manufacturing has become the research focus of relevant units at home and abroad in recent years, mainly two referenceable technologies, which are tool-less AFP proposed by German Aerospace Center / US NIAR Advanced Technology Laboratory and CN114013068A as a representative of a kind of annular silk laying machine tool and silk laying method. First, tool-less AFP uses traditional automatic placement head and supporting roller against it, which is carried by double mechanical arm in space to complete automatic placement, which can realize moldless automatic laying. But due to the drastic change of temperature, the non-equilibrium distribution of material, although there is a supporting wheel to ensure the laying track, there is still a lot of thermal stress and solidification deformation under the condition of no mold, which is difficult to realize accurate additive manufacturing in principle. Second, the annular silk laying machine tool and silk laying method, when the different surfaces of the mold need to be silk laid, only the circular ring needs to be controlled to drive the mechanical arm, and then the silk laying head is moved to the corresponding surface to be silk laid. It saves the time of turning over the mold, greatly improves the silk laying efficiency. However, this method still depends on the mold, and has the constraint of rotary deposition. Therefore, there is no equipment to realize the structure of general moldless additive manufacturing.

[0005] The utility model aims at solving the problem of fast and accurate manufacturing of composite laminated plate components in the current aerospace field, and proposes a double-spindle mirror horizontal automatic laying device. The device has 12 degrees of freedom through the combination of the screw slide module and the mechanical arm, and the double laying mechanism is symmetrically distributed on both sides of the component center surface and does not depend on a special mold. The double laying mechanism supports the component, and mirror additive manufacturing of flat and slightly curved components is realized by the form of counter-laying, which always maintains mirror symmetry along the center surface and thermal field, significantly reduces the warping deformation of the composite laminated plate component, and significantly shortens the manufacturing cycle due to the mold-independent feature. Utility model content

[0006] The utility model discloses a kind of double-spindle mirror horizontal automatic laying devices for the problem that the composite laminated plate component in the current aerospace field depends on mold, and mold manufacturing cycle is long, and easy warping deformation, break through the limitation of original mold manufacturing method, 12 degrees of freedom double laying mechanism mirror symmetry motion along center surface both sides, trajectory symmetry, temperature symmetry, interaction support, provide a new idea for the equipment realization of moldless additive manufacturing.

[0009] The motion control system is symmetrically installed on the two sides of the machine tool in mirror image, so that the laying mechanism always keeps mirror image symmetric movement on the two sides of the center surface.

[0010] The double laying mechanism is symmetrically distributed along the two sides of the component center surface, and the pressing direction is arranged along the normal direction of the center surface; the double laying mechanism moves along the laying track at the same time, and provides support force for each other, and the extruded material is stacked layer by layer along the center surface direction towards the two sides.

[0011] The double laying mechanism is composed of four basic mechanisms of re-feeding, heating, pressing and cutting.

[0012] The double laying mechanism is provided with a distance sensor for measuring the actual position of the laid material in real time, calculating the deviation of the actual position from the theoretical position of the component, and further compensating the deviation of the laying track in the normal direction of the center surface.

[0013] The beneficial effects of the utility model are:

[0014] The laying device can break away from the dependence on the mold in part manufacturing scenes, significantly reduce the warping deformation problem of the composite laminated plate component, and significantly shorten the manufacturing cycle. BRIEF DESCRIPTION OF DRAWINGS

[0028] Before manufacturing, a model of the micro-curved component is first obtained. Its geometric center plane is extracted from the model, and pre-additive manufacturing is performed using PEEK, the same matrix material as the component, to obtain a thin, weakly rigid resin layer with the exact same shape as the center plane. After the center plane layer is manufactured, it is clamped and fixed by eight clamping mechanisms to ensure that the center plane will not shift due to stress during manufacturing. After pretreatment, the initial placement position is set, and the two spindles are coordinated to ensure that the placement heads are collinear and collinear with the normal of the curved surface to be placed. The two placement mechanisms are symmetrically distributed apical to both sides of the center plane, and the necessary external conditions for molding are applied. During placement, the center plane layer is heated and melted by the placement heads, which press the material onto the center plane layer, compacting it and allowing it to solidify along with the center plane layer.

[0029] The parts of this utility model not covered herein are the same as those in the prior art and are implemented using existing technology.
