Forming device of equal-height honeycomb sandwich structure

Abstract

The invention discloses a forming device of an equal-height honeycomb sandwich structure. The forming device comprises a base, a pressure equalizing cover plate and sliding stop blocks. A pit is formed in the center of the base, steps are arranged on the left side and the right side of the base, and fixed baffles are arranged on the front side and the rear side of the pit in the center of the base; the sliding baffles are arranged on the steps on the left and right sides of the base and embedded with the steps; the pressure equalizing cover plate, the base, the sliding stop blocks on the leftside and the right side and the front and rear fixed baffles define a cuboid recess, the equal-height honeycomb sandwich structure is placed in the cuboid recess, and the pressure equalizing cover plate is placed above the equal-height honeycomb sandwich structure. The integrated stop blocks are arranged on the periphery of the forming device, and shrinkage and collapse of the honeycomb core structure due to stress in the X direction and the Y direction can be prevented; the pressure equalizing cover plate provides uniform pressure during forming so that the bonding strength of a workpiece isensured; the cavity area is adjustable in the Z direction and can be used for forming workpieces with different heights and sizes; and the detachable sliding stop blocks on the left side and the rightside are convenient and rapid to install and detach.

Description

technical field [0001] The application relates to a molding device for a honeycomb sandwich structure of equal height, 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 heat and vibration insulation performance, 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 design specifications 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 an equal-height hone...

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.
