Abstract
The present invention relates to a kind of spiral winded type sheet metal elbow, the elbow is connected by a strip spiral winding and formed.The strip thickness is the sheet metal of 0.4 2.0mm.The strip is galvanized sheet, stainless steel plate, color steel or aluminium alloy plate.Advantage is：Using a strip spiral winding connection structure, can continuous automatic production, raise labour productivity.With making by hand than 40 times of efficiency can be improved, cost of manufacture is greatly reduced.Product quality can be guaranteed simultaneously.Elbow uses the structure of spiral winding, rigidity enhancing, and vibrating noise reduces during use, and air tight, it is arc-shaped that this kind of structure can be more nearly the radian of elbow, therefore reduces resistance, reduce Oscillation Amplitude, thereby reduce noise, saved the energy.
Description
Technical field
The invention belongs to building ventilation field of air conditioning more particularly to a kind of circular metals such as air-conditioning, dedusting, smoke evacuation that are used for lead to
The spiral winded type sheet metal elbow of wind pipeline.
Background technology
Mainly circular pipe is made with sheet metal in ventilation, air-conditioning, dedusting, smoke evacuation, the light material conveying of building interior, also referred to as
Air hose circulates for two places gas.Most popular air hose is closed with galvanized sheet, stainless steel plate, aluminium in construction market at present
Golden plate, color steel make, and are connected at pipeline turning with the elbow of same material.Common elbow is curved for more piece in present construction market
Head is commonly called as dried shrimp waist, sees Fig. 1, Fig. 2.This elbow mainly makes of pure manual or manual plus Simple mechanical, low there are efficiency,
It is of poor quality, the problem of rigidity is inadequate, building interior using when in the presence of vibration is big, noise is big, gas leakage, energy loss is big asks
Topic, and add construction engineering cost.
The content of the invention
For overcome the deficiencies in the prior art, the object of the present invention is to provide a kind of spiral winded type sheet metal elbows, use
It is connected in air hose turning, improves rigidity, vibration is reduced during use, avoids gas leakage.
To achieve the above object, the invention is realized by the following technical scheme：
A kind of spiral winded type sheet metal elbow, the elbow are connected by a strip spiral winding and formed.
The strip thickness is the sheet metal of 0.4-2.0mm.
The strip is galvanized sheet, stainless steel plate, color steel or aluminium alloy plate.
Strip the widest part L1 is not more than 250mm, and most narrow place L2 is 30~70mm.
The strip both sides of the edge are wavy curve.
Compared with prior art, the beneficial effects of the invention are as follows：
Spiral winded type sheet metal elbow use a strip spiral winding connection structure, can continuous automatic production,
It raises labour productivity.With making by hand than 40 times of efficiency can be improved, cost of manufacture is greatly reduced.Product quality can be with simultaneously
It is guaranteed.Elbow uses the structure of spiral winding, rigidity enhancing, and vibrating noise reduces during use, air tight, this kind of structure
The radian of elbow can be made to be more nearly arc-shaped, therefore resistance is reduced, reduce Oscillation Amplitude, thereby reduce noise, save
The energy.

Specific embodiment
The present invention is described in detail with reference to Figure of description, it should be noted that the implementation of the present invention is unlimited
In following embodiment.
See Fig. 3, a kind of spiral winded type sheet metal elbow, the elbow is connected by 1 spiral winding of strip and formed.
See Fig. 4, junction uses molding machine, bending is carried out continuously to strip, spiral winding reel forming, seaming, cutting formed it is curved
Head enhances the rigidity of elbow, and vibrating noise reduces during use, air tight.This elbow can be 90 °, 45 °, 60 °, 30 ° etc. it is more
Kind camber, diameter can be any specification, and typical diameters specification is 100-2000mm.
See Fig. 5, for 1 two sides of strip along being waveform, strip 1 is the sheet metal that thickness is 0.4-2.0mm.According to elbow and
Diameter is different, it is preferable that elbow widest part width L1 is not more than 250mm, and most narrow place's width L2 is 30-70mm.The material of strip 1 can
For sheet metals such as galvanized sheet, stainless steel plate, color steel, aluminium alloy plates.
See Fig. 3-Fig. 6, the making of spiral winded type sheet metal elbow comprises the following steps：
1) blanking is carried out according to elbow expanded view, edge is made as waveform using laser cutting machine or plasma cutting machine
The strip 1 of 0.4-2.0mm thickness, is shown in Fig. 5, and the length of strip 1 is determined according to the diameter of elbow and quantity, and strip 1 can disposably most
Long 2000 meters of blanking；Strip is batched to form strip volume, in order to subsequent continuous production；
2) when making elbow, with machine by 1 waveform side flanging of strip, formed while upwarping, another side has a downwarp, by-level
Shape, see Fig. 6, by 1 continuous winding reel of strip formed helical structure, adjacent strip 1 upwarp end with have a downwarp end be engaged, company
Continuous rolling forms single-lock welt structure and is fitted on elbow outer wall, sees Fig. 3, Fig. 4, through this Continuous maching up to one elbow of completion
It makes, then along 2 cutting plate band 1 of cutting line, then second elbow of Continuous maching, until the strip coiled strip is use up.
Spiral winded type sheet metal elbow use a 1 spiral winding connection structure of strip, can continuous automatic production,
It raises labour productivity.With making by hand than 40 times of efficiency can be improved, cost of manufacture is greatly reduced.Product quality can be with simultaneously
It is guaranteed.Elbow rigidity enhances, and vibrating noise reduces during use, and air tight, resistance is small, has saved the energy.
