Abstract
The invention discloses a kind of holding method of honeycomb core, configure gypsum solvent in proportion first, then honeycomb core is placed in framework, gypsum solvent is filling in honeycomb core and framework and floating, finally remove moisture-curing.Gypsum increasing after the solidification rigidity of honeycomb core, can be prevented effectively from honeycomb core mismachining tolerance because caused by hanging.Honeycomb core is immersed in the water after processing, ultrasonic vibration can remove gypsum, gypsum can be recycled.The present invention has holding apparatus simple, high, harmless, the easy to operate advantage of fixing quality, realizes the seamless clamping of honeycomb, enhances the machinability of honeycomb core.
Description
Technical field
The present invention relates to a kind of special holding method, more particularly, to a kind of holding method of honeycomb core.
Background technology
Honeycomb core is a kind of thin-walled loose structure, and wall thickness is generally 0.03 ~ 0.1mm, and the cell length of side is generally 3 ~ 8mm, this
So that honeycomb core has larger rigidity along direction outside face, and the equivalent stiffness in direction is smaller in face.Due to honeycomb core knot
The particularity of structure so that once its direction stress in face is easy to be deformed even by conquassation, so the fixing of honeycomb core
Method is always the problem in honeycomb process.
Traditional holding method mainly has：Double-sided adhesive tape method, polyethylene glycol method and magnetic field absorption method.
Double-sided adhesive tape method is to complete the fixation of honeycomb core using a kind of special adhesive tape, and it is actually a kind of
" line " contact fixed form there is provided fixing power it is smaller, machining accuracy is low.
Polyethylene glycol method is that polyethylene glycol first is heated into molten condition, honeycomb core press-in to be processed wherein, is kept
Pressure solidifies until polyethylene glycol, and this is that one kind is the fixed form that " face " is contacted, and it is firm to hold, but is due to need to poly- second
Glycol is heated and cooled down, and cost is high, the cycle is long, and residue is harmful and is difficult to remove.
Magnetic field absorption method is to produce electromagnetic attraction to pouring into the iron powder in honeycomb core cell using high-intensity magnetic field platform so that iron
Powder is under the collective effect of self gravitation and magnetic attraction force, the friction between increase iron powder and honeycomb wall, iron powder and clamping platform
Power, this method fixing is reliable, automaticity is high, but there is iron powder can wear and tear stage property, reduce cutter life, fixing
The more complicated shortcoming of equipment.
The content of the invention
The present invention is in view of the above-mentioned problems, with reference to the particularity of honeycomb core structures, carried out research invention.The purpose of the present invention
It is to provide a kind of holding method of honeycomb core.
The present invention to achieve the above object, is adopted the following technical scheme that：
A kind of holding method of honeycomb core, step is：
Land plaster and water are mixed and are modulated into pasty state；
Honeycomb core part is put into the frame structure slightly larger than honeycomb core chi；
The gypsum of modulation is filling in honeycomb core and framework and floating；
Honeycomb core and frame structure are put into baking oven, make gypsum baking and curing；
After being machined to honeycomb core, it is dipped in water, ultrasonic vibration removes gypsum.
The configuration proportion of the land plaster is volume fraction 70-95%
The drying temperature is 100----120 DEG C.
The structural material of the honeycomb core includes titanium alloy, high temperature alloy, stainless steel.
The technical effects of the invention are that：A kind of holding method of honeycomb core of the present invention, can be increased using the gypsum of solidification
The rigidity of strong honeycomb core, it is to avoid the mismachining tolerance because of caused by honeycomb core pendulous tank.The holding method has holding apparatus
Simply, high, the easy to operate advantage of fixing quality, realizes the seamless clamping of honeycomb core, enhances adding for honeycomb core structures
Work.
