Problems solved by technology

In China, honeycomb clamping and positioning mainly adopt the method of sticky buckle and adhesive, which has low work efficiency and high labor intensity, and the honeycomb is easily subjected to milling force during processing to produce horizontal deformation (vertical fiber direction), which ultimately affects Machining accuracy

Embodiment Construction

[0011] Newly design (or use existing) a clamping platform (ferromagnetic material), set induction coils on the clamping platform, generate a magnetic field parallel to the fiber direction during work, magnetize the iron powder, and make the iron powder generate downward pressing force (able to control). The honeycomb is placed on the platform according to the clamping requirements, and then an appropriate amount of iron powder is evenly poured into the honeycomb. The maximum height of the magnetic material is smaller than the lowest processing surface of the workpiece, and then a layer of aluminum powder is poured on the iron powder. Through several times of alternating magnetic field, the effect of compaction is produced on the iron powder. Then pour a layer of material that can effectively isolate the magnetic field on the iron powder. At this time, the stress state of the iron powder in the honeycomb is shown in Figure (3). Under the action of a strong magnetic field forc...

Abstract

A method for machining the flexible material with cellular structure includes putting said cellular flexible material vertically on a fixture platform with induction coil, filling magnetic material into the cavities of honeycomb, adding a layer of non-magnetic material on the field magnetic material, turning on said induction coil on the fixture platform, and machining according to technological requirement. Its advantages are simple equipment, high machining accuracy and high productivity.

Description

technical field [0001] The invention relates to a processing method of a honeycomb flexible structural material. Background technique [0002] In aircraft construction, composite materials are increasingly used. As a composite material, honeycomb has the advantages of light weight and high fiber direction strength, so it has been widely used in the aviation field. Foreign countries keep these key processes and tooling technologies related to the application of new materials and specific manufacturing secret. At present, it is still difficult for us to obtain such core manufacturing technologies from technical literature, patents or foreign inspections. Therefore, how to solve the problem of clamping, positioning and processing of honeycomb composite materials that has puzzled my country's aviation manufacturing field for many years is of great significance and value for shortening the development cycle of new models and accelerating the pace of model production. ...
