Problems solved by technology

In the 1980s, NASA implemented the Advanced Composite Technology Research Program (ATC) and the Subsonic Stitched Wing Program (AST) to promote the development of suture composite material technology. The early automatic sutures mostly used bilateral sutures and the suture equipment was large in size, so not widely used
However, for sandwich struc

Abstract

The invention discloses a sandwich structure composite material preform sewing head with a pre-puncturing function, and belongs to the technical field of sewing devices. The sandwich structure composite material preform sewing head comprises a pre-puncturing mechanism, a sewing mechanism, a swinging mechanism and a presser foot mechanism, wherein the pre-puncturing mechanism drives a pre-puncturing crank disc to drive a pre-puncturing needle to realize pre-puncturing action by virtue of a servo motor and a speed reducer; the sewing mechanism drives a sewing crank disc to drive a sewing needleto realize sewing action by virtue of a servo motor; the pre-puncturing mechanism and the sewing mechanism are mounted on a swinging plate; the swinging mechanism pushes the swinging plate by virtue of an aluminum tube cylinder to realize replacement action of the pre-puncturing needle and the sewing needle; the presser foot mechanism drives a ball screw by virtue of a servo motor to drive a standard cylinder to horizontally move; and the cylinder drives a presser foot to move up and down. The sandwich structure composite material preform sewing head is compact in structure, realizes automaticsewing of a sandwich structure composite material, and improves production efficiency and product consistency.

Description

technical field [0001] The invention belongs to the technical field of suture devices, and in particular relates to a suture head for a composite material prefabricated body with a pre-puncture function. Background technique [0002] The sandwich structure composite material prefabricated body is composed of a sandwich layer and two surface layers. It has the characteristics of high strength, shock absorption and noise reduction, impact resistance, and light weight. It is currently widely used in various fields such as medical care, automobiles, aerospace, aviation, and construction. . Since the 1970s, foreign researchers have done a lot of research work on composite material sewing technology, and developed a variety of interlayer reinforcement methods to enhance the interlayer performance of composite materials. In the 1980s, NASA implemented the Advanced Composite Technology Research Program (ATC) and the Subsonic Stitched Wing Program (AST) to promote the development of...
