Of the present inventionly heat insulationly be rolled into template with multilayer and accomplish multilayer through following method and be rolled into template: utilize format roll (forming roll); Through several stages; The vertical projection that forms on the metallic plate more than two; Thereby these metallic plates are close to and moulding manufactures overlay mutually, are finally utilized roll the horizontal recessed song of said overlay.
The formation that the final multilayer of accomplishing of the present invention is rolled into template is shown in Fig. 2 (b); It is a kind of continuously structure of first projection 41 and second projection 42, the 3rd projection 43 repeatedly; Wherein, First projection 41 is through the symmetrical structure of format roll 100 and roll 200 moulding, and second projection 42, the 3rd projection 43 form to diagonal is outstanding at the left and right sides of said first projection 41.
Promptly; Said first projection 41 by format roll 100 after the tab-like one-tenth in top " II " type projection 20; The upper end of said " II " type projection 20 is expanded to the outside, both sides by roll 200; Be shaped to the form of the recessed song in the left and right sides (corrogate), thereby increase the surface area of thermo-contact, bring into play outstanding effect of heat insulation.At this moment, because therefore the symmetrical structure that the upper end of said first projection 41 is expanded about being forms certain space between first projection 41 and plate bottom surface in the forming process of first projection.
And, form second projection 42 in the left side of said first projection 41, form the 3rd projection 43 on the right side, said second projection 42 and the 3rd projection 43 are the structure that the center constitutes symmetrical shape with first projection 41 between them.In addition; Said second projection 42, the 3rd projection 43 through format roll 100 behind top tab- like triangularity projection 30a, 30b; Pushed downwards by roll 200; Thereby the upper end of said denation 30a, 30b is extended and outstanding formation to diagonal up, thereby form the form of recessed song laterally.At this moment, between the upper end part of second projection 42 that diagonal extends to form, the 3rd projection 43 and plate bottom surface, formed spatial portion 50 by roll extruding downwards.So, because shape that the surface area of second projection 42 of diagonal moulding, the 3rd projection 43 increases and the spatial portion 50 that between them, forms; Therefore can guarantee to be used for heat insulation more and space sound insulation; Thereby not only can improve heat insulation and sound insulation value; And when with forcing press (press) when format roll is pressed into template; Second projection 42 of on diagonal moulding, the shape of the 3rd projection 43 are acted on neatly, therefore carry out multiple processing and forming, thereby and make stable stickup of each metallic plate can prevent disengaging up and down according to the operation purpose.
At this moment, preferred said second projection 42, the 3rd projection 43 to the outstanding angle (α) of up diagonal at 5 °-30 °.When said angle (α) during less than 5 °; Because of the spatial portion 50 that forms between second projection 42, the 3rd projection 43 and the plate bottom surface diminishes; The effect of heat insulation and sound insulation is reduced, when angle (α) surpasses 30 °, because of the extension ledge of the upper end of second projection 42, the 3rd projection 43 forms excessive angle; Not only make the formation of said spatial portion 50 become difficult, and make the effect reduction that prevents that each metallic plate breaks away from.
In addition, shown in Fig. 2 (c), the spatial portion 50 that between said second projection 42, the 3rd projection 43, forms can also form conical projections 35, and said conical projections 35 can use format roll 100 to come moulding.Said conical projections 35 improves the effect that prevents that each metallic plate laterally breaks away from.
At this moment, preferably, said each metallic plate is made up of the thin plate below the thickness 0.5mm, and this is because its weight increases when the thickness of metallic plate surpasses 0.5mm, and mouldability and machining accuracy are reduced.And, for help processing, mouldability and product lightweight more preferably each metallic plate constitute by aluminium sheet.

Make at the overlapping metallic plate of said S10 step and pass through between the format roll 100 shown in Figure 4, thereby form to top outstanding " II " type projection 20 and denation 30a, 30b shape (S20 step).At this moment; When once property forms continuous " II " type projection 20 repeatedly with denation 30a, 30b on metallic plate; The possibility of metallic plate fracture improves, thereby hinders stability, therefore on the configuration structure of roller as shown in Figure 5 of the present invention; That kind as shown in the figure is not a plurality of projections of moulding simultaneously once; But, form a plurality of " II " type projection 20 and denation 30a, 30b through increasing a plurality of steps of hop count process of roller, obtain the effect of roll-forming metallic plate stably thus.
At this, shown in Fig. 6 (b), the spatial portion between said denation 30a, 30b also can form conical projections 35 (S25 step) together.Said conical projections 35 also be through with metallic plate through forming, can further improve the metallic plate that prevents to overlap to form between the format roll 100 in the horizontal effect of disengaging.
And make its recessed song with " II " type projection 20 that forms in the said S20 step of roll 200 extruding with denation 30a, 30b, thereby form: first projection 41, its upper end are expanded to the left and right and are formed symmetrical structure; Second projection 42, the 3rd projection 43, they are that the center makes the upper end extend and outstanding laterally to diagonal up in its both sides with said first projection 41; Spatial portion 50 is between the bottom surface of the upper end of said second projection 42, the 3rd projection 43 and metallic plate (S30 step).
At this moment, also can also push, make heat insulation that each metallic plate overlaps each other and be rolled into template with multilayer with 200 pairs of said conical projections 35 of roll.
Fig. 3 representes the heat insulation plan structure that is rolled into template with multilayer that manufacturing method according to the invention is produced; The multilayer of pushing by the format roll superpose-forming with roll is rolled into template; Thereby make the recessed bent cylinder shapes that become of " II " type projection 20, and to make denation 30a, 30b be the recessed song in the left and right sides, center with said " II " type projection 20.
