A molding device for equal-height honeycomb sandwich structure

Abstract

The invention discloses a molding device of a honeycomb sandwich structure of equal height, which comprises a base, a pressure equalizing cover plate and a sliding block, a depression is arranged in the center of the base, steps are arranged on the left and right sides of the base, and the front and rear sides of the depression in the center of the base are arranged Fixed baffles; sliding baffles are set on the steps on the left and right sides of the base and fitted with the steps; pressure equalizing cover plate; the base, the sliding baffles on the left and right sides and the fixed baffles on the front and rear surround a cuboid depression, equal height honeycomb The sandwich structure is placed in the cuboid depression, and the pressure equalizing cover plate is placed above the equal-height honeycomb sandwich structure. The molding device of the present application is surrounded by integrated stoppers, which can prevent the shrinkage and collapse of the honeycomb core structure in the X and Y directions; the pressure equalizing cover plate provides uniform pressure during molding, ensuring the bonding strength of the workpiece; the cavity area It can be adjusted in the Z direction and can be used to form workpieces of different heights and sizes; the detachable sliding stops on the left and right sides are convenient and fast to install and disassemble.

Description

technical field [0001] The application relates to a molding device of an equal-height honeycomb sandwich structure, which belongs to the technical field of composite material manufacturing and molding. Background technique [0002] The composite honeycomb sandwich structure has been widely used in the aerospace field because of its high specific strength, high specific stiffness, good thermal insulation and vibration isolation, and strong designability, especially in modern aircraft structures. The core structure has gradually become the main load-bearing structure. As a load-bearing structural component of an aircraft, it is necessary to determine whether its mechanical properties meet the requirements of design technical indicators before use. For the honeycomb sandwich structure, the commonly used method to determine its mechanical properties is to test the plate-core tensile strength of the furnace parts corresponding to the parts. The structure of the furnace parts is ...

AI Technical Summary

Problems solved by technology

Due to the influence of factors such as the size / material of the bar and the proficiency of the operator, the traditional method cannot completely solve the shrinkage and collapse of the honeycomb core structure after being compressed in the X and Y directions of the honeycomb core with equal heights, especially for the molding pressure.
