Description
Technical field
The present invention relates to hold down gag, relate in particular to a kind of pre-compressing device of honeycomb flexible material processing and fixing.
Background technology
Honeycomb flexible material is a kind of advanced person's an aviation composite, have lightweight, high-strength, advantage such as density is low, and can in a big way, select and adjust as required according to density, with the Nomex honeycomb is the sandwich structure piece that core is made, its specific strength, specific stiffness are about 9 times of steel, and simultaneously honeycomb flexible material has corrosion-resistant, shock resistance, antifatigue, absorption vibrational energy and Heat stability is good and a series of good characteristics such as good insulating properties and saturating electromagnetic wave.The application of honeycomb flexible material has had three significant historical events at first from aerospace field since it drops into application.First is No. 2100, first eight commercial aircraft-Lille virtue of the U.S., the only heavy 567kg of this airplane, and it is small and exquisite, in light weight and express one's surprise, wonder, etc in generation with structure; Second is shuttle Columbia; The 3rd is the Boeing-767 airliner.Honeycomb flexible material is in these several carry-on successful Application, shown the serviceability that honeycomb flexible material is good and the maturation of manufacturing technology, and these achievements have promoted composite and apply paces on important engineering structure.
Be accompanied by industrial expansions such as Aero-Space, honeycomb core structures is as a kind of novel structural composite material, and its number of applications and range of application increase day by day.In building trade, adopt honeycomb core structures to make body of wall, can alleviate casualties and property loss that earthquake causes greatly; In auto industry, honeycomb flexible material is mainly used in vehicle body exterior skin, body structure, body frame structure for automotive, bumper, seat, car door etc. and locates; In shipping industry, it is heavy to reduce ship to adopt honeycomb flexible material to make bulkhead, improves the flexibility and the stability of ship; A new generation is progressively adopting in the high-speed train compartment honeycomb core structures to replace FRP, steel plate, aluminium sheet.Italy ETR460 of new generation, 470,500 high-speed trains, the Hexlite310 honeycomb flexible material that adopts Hexel company to provide is made side plate, top board and the luggage compartment etc. in compartment, thereby make carriage weight from original 12 tons/reduce to 4 tons/joint, reduced the load of the weight in compartment and axletree, track, make still to reach high-speed target (the ERT500 speed of a motor vehicle is greater than 200km/h) when old track travels continuing to use, and reduced power consumption and maintenance cost effectively.
Honeycomb flexible material is as a kind of novel composite material, owing to have various good physical properties, its application is also in continuous expansion, but because this new material unique appearance structure and special anisotropy mechanical property make its holding method that is adopted in the high-speed milling process also be different from general metal material fully.Common honeycomb core part is similar to the plate parts in the metal material processing, and the part area is very big, very thin thickness, and the rigidity of part itself is relatively poor.In metallic plate class material processing, the holding method that adopts usually is vacuum suction method and magnetic field absorption method at present.The vacuum suction method is mainly used in the Milling Process of plate parts, and the magnetic field absorption method is mainly used in the grinding of plate parts.Effect by vacuum pressure or magnetic field force makes the bottom surface of metal plate parts and the surface of fixing platform fit tightly, thereby reaches clamping, fixing to the metal plate parts.At present, be applicable to that the main holding method of honeycomb core part has following four kinds: (1) polyethylene glycol method, (2) double-sided adhesive tape method, (3) diaphragm process, (4) magnetic field and friction absorption method (the patent of invention ZL of Zhejiang University 01135679.0).During methods such as employing polyethylene glycol, double-sided adhesive tape, barrier film, the workman needs constantly with sandbag the honeycomb core part to be patted in fixing part process, is fitted in honeycomb core part bottom surface and fixing platform surface as far as possible.But this method uses acetone as cleaning agent, can cause environmental pollution, and this type of material of Long contact time also has carcinogenic danger.A large amount of production practices show that also the retain strength that this holding method provides is little, fixing reliability, poor stability.The diaphragm process cost is high, is seldom adopted by factory generally speaking.The holding method based on magnetic field and friction absorption that Zhejiang University proposes belongs to the honeycomb holding method of pure physical process, has simple to operate, advantages such as fixing is reliable, with low cost, green.A kind of spring attachment based on arranged in arrays that the present invention proposes is mainly used in the supporting use of patent of invention ZL 01135679.0, and the honeycomb that solves before the filling ferrous powder particle compresses problem in advance, thereby further improves the machining accuracy of honeycomb flexible material.
