Low-density honeycomb plate sandwich manufacturing and stretching forming device and treatment method thereof

Abstract

The invention relates to a low-density honeycomb plate sandwich manufacturing and stretching forming device and a treatment method thereof. The forming device comprises a bearing table, a stretching limiting mechanism arranged on the bearing table, a stretching driving mechanism arranged on the bearing table and a pair of stretching clamping mechanisms arranged on the stretching driving mechanism,wherein the bearing table comprises two vertical side plates and a horizontal bearing plate positioned between the two side plates; the pair of stretching clamping mechanisms are arranged in a mirrorsymmetry mode relative to the symmetrical surfaces of the two side plates; the pair of stretching clamping mechanisms are positioned above the bearing plate; the stretching driving mechanism can drive the pair of stretching clamping mechanisms to move in the opposite direction or in the opposite direction; and the stretching limiting mechanism is used for limiting the distance between the pair ofstretching clamping mechanisms moving in the opposite direction. According to the forming device, limiting stretching can be realized, the stretching effect is good, the stretching is ensured to reach a preset stretching amount, and the stretching deformation is prevented.

Description

technical field [0001] The invention relates to the technical field of honeycomb plate processing, and specifically provides a low-density honeycomb plate sandwich manufacturing stretch forming equipment and a forming method. Background technique [0002] Honeycomb panel is a board made of two thinner panels firmly bonded on both sides of a thicker honeycomb core, also known as honeycomb sandwich structure; honeycomb core is a low-density honeycomb material. As the core material of the sandwich structure; more than 500 different materials can be used to manufacture, the main honeycomb core materials are aluminum alloy, glass fiber fabric impregnated with resin, aromatic fiber paper, kraft paper, graphite fiber and Kevlar fiber, etc. , The resin content is about 50%; honeycomb holes have many different shapes, such as hexagonal, rectangular, reinforced, etc., and their performance depends on the material, cell shape and size. [0003] In the process of honeycomb panel proces...

AI Technical Summary

Problems solved by technology

[0004] 1. During the stretching process, the stretching force is uneven, and stretching deformation is prone to occur, that is, the honeycomb cells formed by stretching are deformed;

[0005] 2. During the stretching process, it is difficult to control the amount of stretching, so that there may be insufficient stretching or excessive stretching
