An automatic preparation device and method for composite honeycomb sound-absorbing cap blank

Abstract

The invention belongs to the technical field of intelligent manufacturing, and relates to an automatic preparation device and method for composite honeycomb sound-absorbing cap blanks. The invention provides an automatic preparation device and method for composite honeycomb sound-absorbing cap blanks. By setting the inside of the punching knife as hollow, the blanks can be sucked to absorb the blanks, and the blanks can be blown down to ensure that the blanks are accurately transported out, and at the same time It does not stick to the punching knife, which solves the problem that the composite honeycomb sound-absorbing cap blank currently relies on manual shearing, which has poor consistency and low efficiency, and is in urgent need of automatic preparation and upgrading; the raw material of the blank is woven fabric, which is soft, easy to burr, It is easy to wrinkle and have static electricity, etc. The blanks that are cut have random falling positions, and they are easy to stick to other objects during the falling process. The blanks are easy to fly out and other problems, and the automatic preparation of the composite honeycomb sound-absorbing cap blanks is realized.

Description

technical field [0001] The invention belongs to the technical field of intelligent manufacturing, and relates to an automatic preparation device and method for composite honeycomb sound-absorbing cap blanks. Background technique [0002] Composite honeycomb is a honeycomb-shaped composite material profile, which is the most widely used in the aerospace field because of its outstanding mechanical property stability, corrosion resistance, flame retardancy, environmental resistance and wave transparency. Composite honeycomb is mainly used in the field of aerospace manufacturing for sound absorption, noise reduction and wave absorption. In the process of processing, it is necessary to prepare an anechoic cap at a specified depth of the honeycomb hole. The quality of the anechoic cap directly determines the quality of the composite honeycomb. Sound absorption and noise reduction effect. [0003] At present, the blanks of composite honeycomb sound-absorbing caps are manually cut,...

AI Technical Summary

Problems solved by technology

[0003] At present, the blank of the composite honeycomb sound-absorbing cap adopts the method of manual shearing, which has poor consistency and low shearing efficiency. There is an urgent need for automatic cutting of the blank.

[0004] The raw material of blanks is woven cloth. Due to the characteristics of soft, easy to wrinkle, easy to burr, and easy to generate static electricity in woven fabrics, there are the following problems in the automatic cutting process of blanks: it is easy to stick to other objects during the falling process, and the blanks Problems such as inaccurate blanking, easy movement of the punching knife to lift the blank, and easy flying of the blank during the transfer of the blank, etc.
