Apparatus and method for cutting specific prepreg shape using ultrasonic cutter

Abstract

A device and method for cutting a specific prepreg shape using an ultrasonic cutter, including an ultrasonic cutter head, positioning pins, a cylinder, and a lead screw; the ultrasonic cutter head is provided with an ultrasonic cutter head; the ultrasonic cutter head is connected to a first drive motor; The ultrasonic tool fixture includes a connecting plate, a top plate is set on the top surface of the connecting plate, a bottom plate is set on the bottom surface of the connecting plate, and an upper end hole is opened on the top plate; a positioning pin hole is opened on the bottom plate, and a screw connection hole is opened on the side wall of the connecting plate , one end of the screw rod extends into the connecting hole of the screw rod and is connected with the positioning pin, and the other end is connected with the second driving motor. The present invention can drive the lead screw to rotate through the second drive motor, and the lead screw drives the ultrasonic cutter head fixture to move horizontally, and can cut out prepregs of a specific shape. The horizontal movement of the ultrasonic cutter head is combined with the motion of the prepreg, thereby cutting The required shape can be made to make up for the "triangular area" defect in engineering applications, so as to ensure that the performance of the prepared components meets the requirements for use.

Description

technical field [0001] The invention belongs to the field of automatic laying process equipment for resin-based carbon fiber prepreg, and in particular relates to a device and method for cutting a specific prepreg shape by using an ultrasonic cutter. Background technique [0002] The samples prepared by resin-based carbon fiber prepreg have the characteristics of high specific strength, high specific modulus, light weight, low density, high fatigue resistance, and high corrosion resistance. At present, resin-based carbon fiber reinforced composite materials have been widely used in the aviation industry. , wind power generation blades, automobile manufacturing and other large industrial fields. Automatic fiber laying technology is the collective name of automatic wire laying forming technology and automatic tape laying forming technology. It is an advanced fully automatic fiber laying technology developed on the basis of fiber winding technology, which can realize large curv...

AI Technical Summary

Problems solved by technology

[0003] The fiber automatic placement technology needs to achieve full pavement in engineering applications, but due to the "triangular area" in the laying process in the path planning, the width of the tape is too large to achieve the purpose of full pavement. Defects in the sample due to failure to achieve full paving, resulting in the consequence that the performance of the product does not meet the requirements for use
