Aviation composite part forming tool with blocking frame

Abstract

The invention discloses an aviation composite material part forming tool with a blocking frame. The aviation composite material part forming tool comprises a tool body, the blocking frame and a magnetic attraction structure, the blocking frame is arranged on a working molded surface of the tool body along the paving edge, the blocking frame is connected with the tool body through the magnetic attraction structure, prepreg is paved on the working molded surface, and the blocking frame is used for supporting the edge of the prepreg. According to the forming tool, the application size can be controlled when the prepreg is applied, application operation contrast alignment is facilitated, then the size of a cured and formed part is controlled, edge shrinkage caused by lateral pressing of a honeycomb core material can be prevented through the arrangement of the blocking frame, and the tool body and the blocking frame are connected through the magnetic attraction structure, so that connectionis reliable, dismounting is flexible, operation is convenient, and damage is not prone to happening after frequent use.

Description

technical field [0001] The invention relates to a molding tool for aviation composite parts. Background technique [0002] When manufacturing aerospace composite parts, it is necessary to lay prepreg on the forming tooling first, and then enter the autoclave for curing and molding. When laying prepreg, the size of the laying should be basically controlled, so as not to be too long or too short, resulting in unqualified parts after curing and molding. For the honeycomb core material, it is also necessary to prevent lateral compression and other defects such as edge shrinkage. Some forming tooling does not have such functions and effects. Contents of the invention [0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a molding tool for aerospace composite parts with a stop frame, which can control the size of the parts and prevent edge shrinkage. [0004] Technical solution: A forming tooling for aerospace comp...
