Description

Technical Field

[0001] The present invention belongs to the technical field of wire laying machines, and in particular relates to a wire laying unit that is compatible with both thermoplastic and thermosetting materials. Background Art

[0002] With the continuous development of technology, large aircraft and large spacecraft are widely adopting lightweight design to obtain a greater thrust-to-weight ratio and improve load-carrying capacity. In addition, the requirements for structural strength are constantly increasing. Ensuring strength while reducing mass has become the core issue of lightweight design. Carbon fiber placement molding technology is one of the best ways to solve this problem. Automatic fiber placement technology has changed the traditional manufacturing process and improved the manufacturing speed of composite components. It has the characteristics of stable placement accuracy, reliable quality, small and uniform fiber bundle gap, and can adapt to the placement of complex curved surfaces in space.

[0003] Fiber placement technology is one of the important means to achieve "low-cost" manufacturing of composite materials. It combines the advantages of fiber winding technology and automatic tape laying technology. Through a placement head that can complete the functions of tow clamping, re-feeding and cutting, the prepreg tow is placed on the surface of the product at a certain angle. It is mainly used for the automatic forming and processing of carbon fiber for complex parts such as large aerospace spherical crown components, vertebral components, load-bearing cylinder components, wall panel components, S-type air inlets, large aircraft fuselages, etc.

[0004] When the wire laying unit in the prior art is in use, the wire laying head is mostly fixedly installed. When it is necessary to switch between thermoplastic and thermosetting materials for laying and winding, it is not possible to switch flexibly. Different wire laying units need to be replaced to switch between laying and winding of different materials. This is not only inefficient and affects the progress of wire laying, but also increases the workload and is not convenient for long-term use.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0006] The object of the present invention is to provide a wire placing unit that is compatible with both thermoplastic and thermosetting materials, which can solve the problem that the wire placing heads of existing wire placing units cannot be flexibly switched, which is not only inefficient but also increases the workload.

[0029] A pair of positioning closed compression rings are fixedly installed on the lower side of the wire placement replacement positioning bin, which can cooperate with the positioning closed spring to enable the positioning closed sealing ring to seal the wire placement head installation tube, so that the wire placement head installation tube will not leak after switching.

[0030] In one or more embodiments of the present invention, a positioning and sealing ring is installed between the positioning and sealing lifting ring and the positioning and sealing compression ring, thereby improving the sealing performance of the positioning and sealing lifting ring and the positioning and sealing compression ring.

[0031] The positioning and closing mounting frame is fixedly provided with a positioning and closing telescopic rod, which can squeeze the extrusion and closing compression plate so that the extrusion and closing compression plate no longer closes the wire placement replacement positioning bin.

[0032] In one or more embodiments of the present invention, the extrusion sealing mechanism includes an extrusion sealing mounting frame, which facilitates the installation of the extrusion sealing balance pole and provides corresponding support for the installation of the extrusion sealing balance pole;
