Split sliding type width-adjustable fiber placement head method and device

Abstract

The invention discloses a split sliding type width-adjustable fiber placement head method and a device. The device comprises a fiber placement head left mounting frame, an electric cylinder is mounted at the upper part of the fiber placement head left mounting frame, the output of the electric cylinder is connected with a fiber placement head right mounting frame, an optical axis, a slidable channel and a sliding support are mounted between the fiber placement head left mounting frame and the fiber placement head right mounting frame, a compression roller is mounted on the optical axis at the bottom and matched with the slidable channel above the compression roller, and the slidable channel is matched with an air cylinder module mounted on a slidable support above the slidable channel. The electric cylinder operates to drive the fiber placement head right mounting frame to move on a polished rod, the slidable channel slides relatively, the width of the channel is changed to adapt to prepreg tapes with different widths, the slidable support slides relatively, the cylinder module freely slides on the guide rail, and it is guaranteed that the cylinder module is located in the center of the fiber placement head and is aligned with the channel below, according to the split sliding type width-adjustable fiber placement head method and the device, waste caused in the cutting process of the prepreg tapes can be reduced, and the influence of non-uniform width of the prepreg tapes caused by cutting is eliminated.

Description

technical field [0001] The invention relates to the technical field of a variable-width silk laying head, in particular to a method and a device for a split-sliding adjustable-width silk laying head. Background technique [0002] Advanced composite materials represented by continuous carbon fiber reinforced resin-based composite materials have the advantages of high specific modulus and high strength, and are widely used in aerospace and other fields, and show an increasingly important position. Composite material automatic placement technology is a low-cost, automated, and numerical advanced manufacturing technology. Due to its advantages of high precision, high speed, and high material utilization rate, it has become the main manufacturing technology of composite material components in the aerospace field. The width of the prepreg tape has a great influence on the laying process, and the design of the corresponding laying head according to the width of the prepreg tape is ...

AI Technical Summary

Problems solved by technology

However, due to the reason of the preparation process, the width of the prepreg tape is difficult to accurately match the width of the laying head. A prepreg tape with a suitable width can be obtained by cutting, but unusable surplus material will be generated, resulting in waste

At the same time, during the cutting process, the direction of the prepreg fiber usually does not match the cutting direction, resulting in uneven width of the cut prepreg

There is a gap between adjacent prepreg tapes during the laying process, which affects the quality of the final product
