Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] refer to Figure 1 to Figure 6 :

[0048] A method for manufacturing a non-equal diameter closed square tubular carbon fiber beam of an unmanned aerial vehicle, comprising the following steps:

[0049] Step 1) Processing upper female mold 3 and lower female mold 4:

[0050] CATIA software is used to optimize the design of the non-equal diameter closed square tubular carbon fiber beam 10 that needs to be processed, divide it into upper beam 1 and lower beam 2, and make corresponding beams according to the divided upper beam 1 and lower beam 2. Upper female mold 3 and lower female mold 4, both ends of upper female mold 3 and lower female mold 4 lengthwise are open type.

[0051] Step 2) Use the upper female mold 3 to process the upper beam 1:

[0052] Clean the upper female mold 3 and apply a release agent, then spread the carbon fib...

Abstract

In order to effectively solve the technical problems of narrow application range, difficult demoulding, low yield of airbag core film, short service life, complicated process and high cost of the existing manufacturing method of non-equal-diameter closed square tubular carbon fiber beams of unmanned aerial vehicles, the present invention A method for manufacturing a UAV non-equal closed square tubular carbon fiber beam is proposed, including steps: 1) processing an upper die and a lower die; step 2) using the upper die to process an upper beam; step 3) Using the lower female mold to process the lower beam; step 4) gluing the upper beam and the lower beam with the gluing and joining tool; step 5) removing the gluing and joining tool to obtain the required non-equal diameter closed square tubular carbon fiber beam. The invention divides the integral component into two parts and forms them separately. Compared with integral forming, the requirements for forming process and forming tooling are lower, and the problem of difficult demoulding of non-equal-diameter closed square tube beams is solved.

Description

technical field [0001] The invention relates to a method for manufacturing a carbon fiber beam for an unmanned aerial vehicle, in particular to a method for manufacturing a non-equal diameter closed square tubular carbon fiber beam for an unmanned aerial vehicle. Background technique [0002] With the development of UAVs, the shape of UAVs is changing with each passing day, and the structural forms of UAV beams are also various. Among them, the non-equal-diameter closed square tubular carbon fiber beam has a better fit than the equal-diameter square tubular carbon fiber beam. The advantages of unmanned vehicle type and superior load-bearing performance. At present, non-equal-diameter closed square tubular carbon fiber beams are mostly manufactured as integral components, and there are generally disadvantages such as difficult demoulding, high production costs, complicated processing, and long processing cycles during molding, and have high requirements on the molding process...
