Automatic preparation device and method for composite honeycomb silencing cap blank

Abstract

The invention belongs to the technical field of intelligent manufacturing, and relates to an automatic preparation device and method for a composite honeycomb silencing cap blank. The invention provides the automatic preparation device and method for the composite honeycomb silencing cap blank. By setting the inside of a stamping knife as a hollow structure, air suction can be carried out to absorb the blank, and air blowing is carried out to blow down the blank so as to ensure that the blank is accurately transported out and meanwhile, is not adhered to the stamping knife, thereby solving problems of poor consistency, low efficiency and urgency of upgrading automatic equipment, which are caused by a case that currently, the composite honeycomb silencing cap blank is depended on manual shearing. The blank uses a woven fabric as a raw material, and has the characteristics that the blank is soft in texture, easy to generate burrs, easy to wrinkle, has static electricity and the like; thecut blank has problems that a falling position is random, the blank is easy to adhere to other articles in the falling process, the blank cannot be accurately blanked, the stamping knife is easy to take up the blank when moving up and the like; and the cut blank has problems that the blank is easy to fly off and the like in the blank transferring process; and automatic preparation of the composite honeycomb silencing cap blank is implemented.

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.
