Heat-insulation aluminium alloy is called broken-bridge aluminum alloy, it be with the nonmetallic materials of lower thermal conductivity (heat insulating strip) by aluminium alloy both
An entirety is separated and closely connected into, a kind of heat-insulated aluminum profile of the heat transfer of aluminium alloy is blocked, according to its complex method
Difference can be divided into penetrating bar type heat-insulation aluminium alloy and glue injection type heat-insulation aluminium alloy.Compared to traditional aluminium alloy extrusions, heat insulation aluminium is closed
Gold heat preservation, sound insulation, impact resistance, air-tightness, in terms of have the promotion of matter, be the one kind for meeting building energy conservation requirement
New Building Materials.
Bar inserting type heat-insulated can be divided into " I " type heat insulating strip heat-insulation aluminium alloy type according to heat insulating strip shape difference
Material, " C " type heat insulating strip heat insulated shape bar of aluminum alloy, " O " type heat insulating strip heat insulated shape bar of aluminum alloy.The present invention is directed to " I " type heat insulating strip
Heat insulated shape bar of aluminum alloy and " O " type heat insulating strip heat insulated shape bar of aluminum alloy, there are double flutes for " I " type heat insulating strip heat insulated shape bar of aluminum alloy
Mouthful, at the same to two notch gear hobbings after, match double branch " I " heat insulating strips, " I " type heat insulating strip heat insulated shape bar of aluminum alloy aluminum amount compared with
More, technique is cumbersome, waste raw material and production auxiliary material；" O " type heat insulating strip heat insulated shape bar of aluminum alloy is single notch, mating to make
With single branch " O " type heat insulating strip, " O " type heat insulating strip heat insulated shape bar of aluminum alloy is compared to " I " type heat insulating strip heat insulated shape bar of aluminum alloy, no
It only reduces and uses aluminum amount (2 " I " type heat insulating strip middle sections), simplify production technology, and saving material (includes profile primary aluminum, type
Material accessory, the various aspects such as equipment part), cost significantly reduces, and has better application prospect.
But due to current gear hobbing technical reason, " O " type heat insulating strip heat insulated shape bar of aluminum alloy mechanical property is not up to standard, serious shadow
Ring its market prospects." O " type heat insulating strip heat insulated shape bar of aluminum alloy mechanical property reason not up to standard is removed heat-insulated by aluminium alloy and " O "
Outside the influence of item quality itself, production operation technique and parameter request are most important；And " O " type heat insulating strip heat-insulation aluminium alloy type
Can material Mechanical Characteristics value up to standard, and gear hobbing, rolling are emphasis, difficult point, the heat insulated shape bar of aluminum alloy mechanics after rolling forming
Or not that performance is up to standard depend on whether gear hobbing tooth depth is up to standard, and the more deep then tooth tip of gear hobbing is sharper, it is stronger to the occlusal ability of heat insulating strip,
I.e. mechanical property is better.According to standard, the tooth tip width of heat insulated shape bar of aluminum alloy adhesive tape groove mouth dentalation is 0.05-
0.10mm just can guarantee its Mechanical Characteristics value >=24N/mm, just can guarantee examination and test of products qualification.And at present in industry due to
Hobbing machine design limitation, after hobbing machine gear hobbing, the tooth tip width of section bar adhesive tape notch dentalation is generally higher than 0.30mm, from
And cause the mechanics properties testing using single " O " type heat insulating strip heat insulated shape bar of aluminum alloy not up to standard.

At present due to hobbing machine design limitation in industry, after gear hobbing, the tooth tip width of profile heat insulating strip notch dentalation
Generally higher than 0.30mm.After assembling heat insulating strip, since notch tooth tip is not sharp, cause notch dentalation to the occlusion energy of heat insulating strip
Power is not strong, and in single branch " O " type heat insulating strip assembling process, in order to promote mechanical property as far as possible, when assembly need to increase roll pan
The rolling power (more than 500Kg power) of application simultaneously rolls repeatedly, and the aluminum profile rolled out is caused to there is the phenomenon that " closing in " deformation.I.e.
Make in this way, its mechanical property is still not ideal enough.Present invention optimizes the structure of hobbing machine, hobbing machine is opened in rolling aluminum profile notch
When tooth, pre- tooth punching is first carried out, and further opens up widen deeply on this basis, so that the tooth rolled out on aluminum profile heat insulating strip notch
The tooth tip width of shape structure is reduced to 0.05mm, and assembly pit mouth dentalation significantly increases the occlusal ability of heat insulating strip, makes "
