Problems solved by technology

The traditional tape laying head adopts the mechanical interlocking of rollers and shoes to achieve the above actions. However, the redundant linkage mechanism added by mechanical interlock is contrary to the lightweight design concept of the tape laying head. In addition, the mechanical interlock lack of reliability

Abstract

The invention relates to a tape laying head suitable for automatic laying and forming of composite materials with variable trajectory, and belongs to the technical field of automatic forming equipment design of composite materials. The invention realizes the electric interlocking function of the pressure roller and the pressure shoe during automatic laying, avoids the redundant structure caused by mechanical interlocking, and realizes the lightweight requirement of the tape laying head. The invention precisely controls the pressing force of the pressing shoe through the cylinder to ensure the close fit of the prepreg and the metal shell, and at the same time, the metal shell will not be deformed due to excessive pressing force. Compared with mechanical interlocking, the present invention has higher reliability by adopting electrical interlocking. It is verified by practical application that the application of the invention to laying the special-shaped composite material structure fully satisfies the self-adaptive laying of complex surfaces.

Description

technical field [0001] The invention relates to a tape laying head and a tape laying method suitable for composite material variable track automatic laying and forming, which belongs to the technical field of composite material automatic forming equipment design, and specifically discloses a composite material variable track automatic laying forming The tape laying head is installed on the mechanical arm, which can realize the automatic follow-up laying of composite materials. Background technique [0002] The special-shaped composite material-metal section is a kind of composite material-metal integrated section formed after the prepreg is automatically laid on the outer layer of the metal shell supported by the inner metal shell, and cured. During the laying process, the tape laying head needs to realize a series of functions such as the first automatic laying of the tape - the separation of the backing paper - the secondary compaction of the tape. The traditional tape la...
