It can adjust；The height of rear leg 62 can be adjusted so that be connected between the driving wheel 20 in the timing belt of rear leg 20
Distance can be adjusted；The height of middle leg can be adjusted so that be connected between the rolling wheel set 40 in the timing belt of middle leg
Distance can be adjusted.
In the present invention, it is designed by the running part to zero Poisson's ratio flexible honeycomb manufacturing equipment, to reach reality
The purpose of the operating of existing equipment.It is to be appreciated that driving wheel 20 in the present invention is using lazy-tongs or synchronous double drives
Dynamic system is driven, it is ensured that the feed speed of timing belt 11, and driven pulley 30 and rolling wheel set 40 can be not provided with motor, only
Rotated by internal tooth 12.Driving wheel 20 and driven pulley 30 are provided with the leg of wheel spacing regulatory function, to adapt to not
With the processing of the flexible honeycomb of size.
During processing, surface treated paper tinsel plate material is first cut into specified width, which width, one section is sent into from feeding mouth 14.
Machine, driving wheel 20 drives timing belt 11 to rotate, and paper tinsel plate material is involved in zero Poisson's ratio flexible honeycomb manufacturing equipment.Roll-in
Forming process is divided into two regions：Roll-in progressive area A1 and formation zone A2, twoth area are boundary with first rolling wheel set 40.
It is to be had angle up and down between timing belt in the progressive area of roll-in, this region first, when aluminium foil enters from feeding mouth 14
When entering roll nip, the crown of external tooth 13 of timing belt 11 starts to extrude paper tinsel plate material, but not at a fully engaged.With paper tinsel plate
Material is fed, and mesh degree is increasing, to level rolling wheel set at it is at a fully engaged.
Next to that it is at a fully engaged between timing belt above and below in formation zone, this region, and clamping force is provided by level rolling wheel set,
Paper tinsel plate material is further pressed into required shape.The final flexible honeycomb individual layer core shaped is spread out of from delivery outlet 15, is passed
The flexible honeycomb individual layer core gone out is as shown in Figure 7.
Finally, to the straight wall lateral surface gluing of the flexible honeycomb individual layer core after shaping, by the individual layer core heap after gluing
It is folded, honeycomb is formed after carrying out solidification by cement, as shown in Figure 6.
It is to be appreciated that in order to produce flexible honeycomb individual layer core as shown in Figure 7, zero Poisson in the present invention
Parameter than each parts of flexible honeycomb manufacturing equipment can carry out the flexible honeycomb for being suitably adapted to need to make
Physical dimension.Below with flexible honeycomb parameter (α=40 °, β=28 °, l=2mm, t=0.05mm, the L=shown in Fig. 1
300mm, W=600mm, H=300mm) the flexible aluminium honeycomb of zero Poisson's ratio exemplified by, introduce zero Poisson's ratio flexible honeycomb manufacturing equipment
Installation and manufacturing process.
1st, the adjustment of zero Poisson's ratio flexible honeycomb manufacturing equipment
Zero Poisson's ratio flexible honeycomb manufacturing equipment includes rolling band 10, driving wheel 20, driven pulley 30, rolling wheel set 40 and feeding
Mechanism 60 etc., each part is demountable structure, facilitates the installation of different parameters timing belt.
Before processing, each driving wheel 20, driven pulley 30 and level rolling wheel set are first removed, is respectively mounted after timing belt 11 is inserted in each
Wheel, and regulate wheel spacing so that when level rolling wheel set is compressed, timing belt 11 is in tensioned state.The regulation spacing of driven pulley 30 makes
Upper and lower tooth at mouth 14 must be sent into not engage completely, two level rolling wheel sets are compressed.
The size of driving wheel 20 and driven pulley 30 is in this exampleEffectively wheel width 300mm.
During processing, first 300mm width will be cut into by the aluminium foil for being surface-treated and drying, its one end is sent from feeding mouth 14
Enter.Machine, driving wheel 20 drives synchronous 11 band to rotate, and aluminium foil is involved in roll-in.Nipping process is divided into two regions：Roll-in
Progressive area A1 and formation zone A2.
In the progressive A1 areas of roll-in, have angle θ between timing belt up and down, when aluminium foil enters roll nip from feeding mouth 14,
The crown of external tooth 13 of timing belt 11 starts to extrude aluminium foil, and as aluminium foil is fed, mesh degree is increasing, until roll-in
It is at a fully engaged at wheel.
The progressive area A1 of roll-in includes m=15 cell length, and cell element length is a width of：
X=l (4cos α -2sin β)=4.25mm
Y=l (2+4sin α+2cos β)=12.674mm
Thus
It is at a fully engaged between formation zone A2, upper and lower timing belt, and provide clamping by wheel spacing for 3Y level rolling wheel set
Power, by a fully engaged, the shape needed for further aluminium foil is pressed into of n=15 cell length.The final flexibility shaped
Honeycomb individual layer core is from the output of delivery outlet 15.
2nd, the two-sided special tooth profile dimensional parameters of timing belt 11
The flexible honeycomb of manufacture is needed to use aluminium foil to be material, and its cell element is shaped as three sections of slope wall types, therefore need design
The two-sided special tooth profile timing belt of correspondingly-sized shape.Timing belt 11 is made of rubber strip, and it is firm to improve stretching containing textle layers
Degree, its internal tooth 12 is common tooth form, is engaged with gear as transmission；External tooth 13 is the shape of flexible honeycomb individual layer core, and it is joined
Number is α=40 °, β=28 °, l=2mm.According to the roll-in stroke needed for progressive molding, the timing belt girth of design need to reach：
C=2 (m+n) Y+2 π φ=1012mm
Add 1 by C/Y round numbers part and be the external tooth number of cells of timing belt 11, the timing belt external tooth number of cells of design is 80,
Its width is 300mm.
3rd, lamination solidification by cement shaping is carried out to the flexible honeycomb individual layer core after shaping.
To the straight wall lateral surface gluing of flexible honeycomb individual layer core, the individual layer core after gluing is stacked, after being solidified
Form honeycomb.
The zero Poisson's ratio flexible honeycomb manufacturing equipment of the present invention uses adjustable progressive rolling equipment, and it is to paper tinsel plate material
Rolling formation process is progressive, it is to avoid impression that direct geared roll-in is produced, curved arc, distortion, wide asked to quality such as bendings
Topic, has the advantages that form stable, technological process are simple, and regulation rolling wheel set is adapted to such various sizes of special-shaped grid honeybee
The manufacture of nest.
More than, it is only the optimal embodiment of the present invention, but protection scope of the present invention is not limited thereto, and it is any
Those familiar with the art the invention discloses technical scope in, the change or replacement that can be readily occurred in, all should
It is included within the scope of the present invention.Therefore, protection scope of the present invention should be defined by scope of the claims.
