Embodiment Construction
[0015] In order to deepen the understanding of the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, which are only used to explain the present invention and do not limit the protection scope of the present invention.
[0016] The invention is a method for post-processing the automatic laying track of the hemming area, and the method comprises the following steps:
[0017] S1. The pressure roller presses the prepreg narrow tape and advances on the first surface, so that the prepreg narrow tape is completely laid on the first surface;
[0018] S2. The main pressure roller presses the prepreg narrow strip and leaves the first surface, and continues to advance in the preset direction of the first surface, so that the prepreg narrow strip extends out of the first surface, and the distance of the pressure roller extending out of the first surface is as follows Calculate as follows:

The invention relates to an automatic wire laying track post-processing method of an edge folding area. The automatic wire laying track post-processing method includes the following steps that S1, a pressing roller presses a prepreg narrow strip and advances forward on a first surface to make the prepreg narrow strip completely lay on the first surface; S2, a main pressing roller presses the prepreg narrow strip and leaves the first surface, and continues to advance in the predetermined direction of the first surface, so that the prepreg narrow strip extends out of the first surface; and S3, the pressing roller moves to a second surface along a preset edge folding track to complete the automatic wire laying of the edge folding and the second surface. According to the automatic wire layingtrack post-processing method of the edge folding area, the flat laying of the prepreg narrow strip located at the edge folding position of a mould can be realized, and the technical problem that the pressing roller warps when encountering the folding edge and consequently the prepreg narrow strip cannot be compacted is solved.
Description
technical field [0001] The invention relates to the field of automatic wire laying and forming of advanced composite materials, in particular to a method for post-processing automatic wire laying tracks in the hemming area. Background technique [0002] Advanced composite materials have the characteristics of high specific strength and high specific modulus, so that they can significantly reduce the structural quality compared with traditional materials on the premise of meeting the same strength requirements, and their status has been unanimously recognized by the aerospace industry. The technology of automatic material laying prepreg narrow tape has the advantages of high forming precision, strong adaptability to curved surface, large laying freedom, etc., and can realize independent cutting, refeeding and compaction of prepreg narrow tape, especially suitable for large curvature Precision automatic molding of large composite components with complex curved surfaces, but ...
