Problems solved by technology

In addition, in the process of processing, the stability of the honeycomb cells is relatively weak, which may easily cause deformation of the honeycomb product, or even collapse of the honeycomb cells, which may directly lead to the scrapping of the product in severe cases
These factors have caused the high cost of honeycomb surface processing

Embodiment 1

[0025] (1) Place the aluminum honeycomb block (400mm×400mm×200mm) to be processed flat in the container, and fix it, fill the aluminum honeycomb cells with water (3°C), and ensure that the aluminum honeycomb block is submerged in water.

[0026] (2) Put the container into the cold storage to cool down, so that the water in the container is frozen, and the water is filled in the aluminum honeycomb cells in a solid form, and the aluminum honeycomb and the ice are integrated, and the aluminum honeycomb filled with ice cubes is removed from the mold. According to the size of the product, it is first sawn into a blank and then directly clamped on the CNC machine tool. It is subjected to various mechanical cutting processes with conventional tools (the ambient temperature of the processing is -6°C) to obtain the designed product shape.

[0027] (3) After the product processing is completed, the aluminum honeycomb product filled with ice cubes is melted at room temperature in a contai...

Abstract

The invention relates to a low-cost honeycomb curved face machining method. The low-cost honeycomb curved face machining method includes the steps that water and to-be-machined honeycomb blocks are placed into a container, and the honeycomb blocks are completely immersed in the water; the water in the container is iced, the honeycomb blocks filled with ice blocks are subjected to demolding and taken out, and are clamped to a numerical control machine tool after being firstly sawn into blank pieces, and mechanical cutting and machining are performed on the blank pieces; then thawing is performed, and after the ice blocks in honeycomb hole grids fall off, honeycomb products are taken out and dried; and the water is recycled and reused, and cutting particles generated in the machining processare collected and treated. According to the low-cost honeycomb curved face machining method, on the basis of the water phase changing icing principle, the honeycomb hole grids are filled with water in a manner that the water is in a solid state manner, a honeycomb and ice are integrated, the honeycomb can be directly clamped on a machining platform like a metal block, depending of the honeycomb curved face products on an auxiliary mold is effectively reduced, the mold preparing time is shortened, and the mold preparing cost is reduced.

Description

technical field [0001] The invention belongs to the field of flexible material processing, in particular to a low-cost honeycomb curved surface processing method. Background technique [0002] In order to further reduce energy consumption, energy saving and emission reduction, aerospace, rail transit and other fields have higher and higher requirements for lightweight. Honeycomb structure materials have excellent characteristics such as light weight, high strength, sound insulation and heat insulation, and fatigue resistance. Outstanding performance in light weight. [0003] The honeycomb core material is a flexible material with poor compressive strength on the side. It is not easy to clamp during CNC machining. It requires a specific mold for auxiliary processing and a special honeycomb tool for processing. In addition, during the processing process, the stability of the honeycomb cells is relatively weak, which may easily cause deformation of the honeycomb product, or ev...
