Abstract
The utility model discloses an integral axial flow fan. Air barrels and flanges in existing axial flow fans are normally welded by air barrels coiled by steel plates and flanges made of steel plates, current collectors and air barrels are also connected through welding, welding influences the integral strength of fans to a certain extent, the production efficiency is reduced, and the production cost is increased. The integral type axial flow fan comprises a flange, an air barrel and a current collector and is characterized in that the flange, the air barrel and the current collector are in an integral structure, and the air barrel is arranged between the flange and the current collector. The flange, air barrel and current collector of the integral axial flow fan are arranged in the integral structure, thereby requiring no welding, improving the integral strength of the air fan and the production efficiency, and lowering the production cost.
Description
Technical field
The utility model relates to ventilation equipment, specifically a kind of integrated shaft flow fan.
Background technique
According to the development trend of present domestic various ventilating engineerings, the underground systems engineering of each big and medium-sized cities is more and more.Axial-flow blower is owing to have advantages such as simple in structure, easy for installation, so the scope of using more and more widely, its market demand also constantly increases, and for the supply producer of axial-flow blower, optimizes the production processing technology and becomes extremely urgent work.
Air duct in the existing axial-flow blower and flange generally are to be welded through the flange that the air duct of steel plate reel moulding and steel plate are made, and slip ring and air duct also adopt and be welded to connect, and are welded on the bulk strength that has influenced blower fan to a certain extent; Each typhoon machine all will pass through operations such as reel, welding, has reduced manufacturing efficiency, has increased cost of production.
The model utility content
The utility model technical problem to be solved is to overcome the defective that above-mentioned existing technology exists, and a kind of integrated shaft flow fan is provided, and with the bulk strength of raising blower fan, and enhances productivity, reduces production costs.
For achieving the above object, the technological scheme below the utility model adopts: the integrated shaft flow fan, comprise flange, air duct and slip ring, it is characterized in that described flange, air duct and slip ring are monolithic construction, air duct is between flange and slip ring.
As preferably, described flange becomes an angle of 90 degrees with the end of air duct.
As preferably, said flange, air duct and slip ring three's consistency of thickness.
The utility model is arranged to monolithic construction with flange, air duct and slip ring, does not need welding, has improved the bulk strength of blower fan, and has improved manufacturing efficiency, reduced cost of production.
Below in conjunction with Figure of description and embodiment the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Integrated shaft flow fan as shown in Figure 1, flange 1, air duct 2 and slip ring 3 are monolithic construction, and air duct 2 is between flange 1 and slip ring 3, and described flange becomes an angle of 90 degrees with the end of air duct.Flange, air duct and slip ring three's consistency of thickness.
The utility model moulding process is the rotary press modelling of circular steel plate cutting, the moulding of hydraulic pressure air duct, slip ring end.Described circular steel plate cutting is for becoming a circle according to calculating good blank size with steel plate cutting; The air duct that described hydraulic pressure air duct is shaped to the circular steel plate materials that will descend through hydraulic equipment comes out from the planar stretch of flange, and stretch position is 4 places among Fig. 1; Described slip ring end rotary press modelling is for becoming the shape of slip ring through spinning machine with the stretching end straight flange spinning of air duct, and the spinning position is 5 places among Fig. 1.
Claims (3)
