Description

A kind of internal layer is the composite air duct and its manufacture method in steel face
Technical field
The invention belongs to the sending of HVAC, return, the composite air duct production field of exhaust system, more particularly, in one kind Layer is the composite air duct in steel face and preparation method thereof.
Background technology
The sending, return of the HVAC of current various advanced composite material (ACM)s, the composite air duct of exhaust system is widely used to The air conditioning duct system of the large size city building bodies such as weaving, chemical fibre, automobile, electronics, medical purification air-conditioning and subway.Such as Fig. 1 and Shown in Fig. 2, existing internal layer is to be opened using 90 ° of special V-tools in internal layer for the processing method of the composite air duct in steel face Groove, close up shaping after glue special is painted in fluting face, then beating glass cement in four interior angles is sealed, finally in airduct two End installation special flange, for the connection between airduct.The shortcomings that prior art:
1st, because interior steel face has been turned off, bonding force of the blast bearing capacity inside airduct mainly by glue.
2nd, due to being sealed using glass cement, after long-play, the easy weathering of glass cement and aging.
3rd, because internal layer steel face alreadyes switch off, the integral rigidity and intensity of airduct substantially reduce.
4th, because the bonding force of glue is limited, easily failed after long-play, airduct service life shortens.
Based on disadvantages mentioned above, people, which need to find more preferably method, solves these problems.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of bulk strength is big, the internal layer of service life length is steel face Composite air duct and its manufacture method.
The technical solution used in the present invention is:
A kind of internal layer is the composite air duct in steel face, it is characterised in that:The composite air duct uses sheet material of the internal layer for steel face Manufacture, the composite air duct includes internal layer steel face, intermediate insulating layer and outer layer, on each medial surface of the composite air duct, Between per two adjacent sides, extend at an angle with being integrally formed on the steel face edge of one of side one end One section of overlap joint steel face, it is described to overlap above the overlapping steel face for snapping into another side in steel face, and in overlapping lap-joint using drawing The mode of rivet locks this overlapping two-layered steel plates two-by-two.
Preferably, the composite air duct is rectangular tube, more optimizedly, the overlap joint steel face is vertical from the edge of steel face Extend, its height is 2 times of the sheet metal thickness for manufacturing the composite air duct.
Preferably, the outer layer of the composite air duct is steel face or aluminium foil.
Preferably, in overlapping, riveted using two pulling rivets.
Preferably, the thickness for the sheet material that the composite air duct uses is 2-5cm.
Preferably, the composite air duct can also be shape tube.
Manufacture method the invention also discloses above-mentioned internal layer for the composite air duct in steel face, comprises the following steps:
Step 1), the internal layer for preparing to make composite air duct are the sheet material in steel face;
Step 2), the forming requirements according to composite air duct, the line of rabbet joint position of V-groove to be opened is determined on the internal layer of sheet material Put, two end lines of each V-groove to be opened are determined according to the line of rabbet joint;
Step 3), one of them V-groove to be opened is chosen, first with end line of the straight line knife along wherein one end of V-groove to be opened Place cuts off internal layer steel face, while the other end end line of V-groove to be opened is pushed down with nose bar, and the internal layer steel face between two end lines is rolled over 90 ° -180 ° are played, then carries out the fluting of intermediate insulating layer with V-tool again;
Step 4), on sheet material each at V-groove to be opened according to step 3)Described method carries out cutting for internal layer steel face Disconnected and intermediate insulating layer fluting is processed, and internal layer steel face is divided into some segmentation steel faces;
Step 5), glue has been brushed at V-groove, whole sheet material is then closed up into shaping, each V-groove turn up after it is adjacent Segmentation steel face has overlapping, and the internal layer steel face in the fluting face turned up is overlapping with the internal layer steel face progress of groove periphery, overlapping Place is by the way of pulling rivet riveting by this two layers of steel face locking.
Preferably, the step 3)In, the other end end line of V-groove is being pushed down with nose bar by the internal layer between two end lines Before steel face turns up 90 ° -180 °, with beading equipment at this end line beading, more optimizedly, bead depth is press-in internal layer steel face The 2/3 of thickness.
Preferably, the step 3)In when being slotted with automation equipment, the other end of V-groove is pushed down with nose bar Internal layer steel face between two end lines is turned up 90 ° -180 ° by end line, and when manually being slotted, the another of V-groove is pushed down with nose bar Internal layer steel face between two end lines is turned up 90 ° by one end end line.So handle, easily produced when allowing for automation equipment fluting Raw winding, when internal layer steel face is turned up more than 90 degree, it is possible to this problem is preferably avoided, when manually being slotted, There is no concern that this problem, and it is just 90 ° to turn up, and waits whole plate one to close up shaping, the internal layer steel face in the fluting face turned up and The internal layer steel face of groove periphery is just overlapping, as long as directly being locked.
Preferably, when the composite air duct for needing to make is square, 90 ° of V-grooves are opened in fluting, use 90 ° of V-types Cutter, it is 90 ° to push down the angle that the other end end line of V-groove turns up the internal layer steel face between two end lines with nose bar.
By adopting the above-described technical solution, the present invention has the following technical effect that:
After above-mentioned processing technology or method, glass need not be broken again at four interior angles of airduct outside glue adhesive surface Glue, had both eliminated the use of glass cement material, and by internal layer steel face is close, effectively connection is locked together, substantially increased The inside bulk strength and blast bearing capacity of airduct, while the service life of airduct is also effectively extended, can be by internal layer list The overall performance of the composite air duct product of face or double-side color-steel significantly improves one grade, and the structures and methods are except square airduct Outside, special-shaped airduct is equally applicable to, practicality is extremely strong, is worthy to be popularized.Meanwhile intensity of the steel face than in general internal layer for aluminium foil Height, repeatedly long-term cleaning can be stood, be damaged in the absence of aluminium foil during cleaning and cause the silty heat-insulation layer of centre Spill.
