Abstract
The utility model relates to a processing equipment for machining metal intake of fan, which consists of a fixed mould and a moving mould, wherein the fixed mould shape is a taper tube type. The upside of the taper tube type and the moving mould form a flanging part of the intake of fan. The flanging part is shaped like a cylinder or other shapes. The other parts of the taper tube type have the same shapes as the other parts of the intake of fan. The moving mould is a ball with a circular arc. The circular are in accordance with the upper part of the intake of fan. The utility model makes the intake of fan have no welding gap, which has no phenomenon of embossment, puckering and breakdown; therefore the surface quality is obviously improved. The more simple processing equipment has more convenient operation, thereby saving investment on the device and equipment. The common machine works can process the equipment. The raw material can be saved by more than double and the work efficiency can be improved by more than 4 times.
Description
Technical field
The utility model relates to a kind of moulds of industrial equipment of blower fan metal air inlet processing.
Background technology
Blower fan metal air inlet as shown in Figure 7, is roughly cone barrel, and the upper oral part of cone barrel is the flange form.If material thickness is t, when t/B≤0.003, H/B 〉=0.38, A/B 〉=0.65 o'clock, it is quite complicated that its moulding process just becomes, and state inner blower producer adopts welding fabrication technology mostly, two kinds of methods is arranged: method one: blanking; The welding cone barrel; Press arc Ra; Press arc Rb.This method development size often is difficult to determine, can only be by rule of thumb.Crease easily easy fracture during Rb when pressing arc Ra.Needing frock is Ra, Rb pressure-shaped mould tool, must finish at the bigger hydraulic press of work top.Method two: air inlet is divided into three parts: flange, cone barrel, arc (flange position), three parts are processed separately, are shaped separately, and welding fabrication needs two cover pressure-shaped moulds and a cover weldering tire then.This method each several part is shaped easier, and shortcoming is that part quality is poor, and operation is loaded down with trivial details.
Summary of the invention
Technical problem to be solved in the utility model provides the moulds of industrial equipment of blower fan metal air inlet processing, and simple in structure, small investment can improve part quality, saves material consumption.
The moulds of industrial equipment of blower fan metal air inlet processing of the present utility model, it is characterized in that forming by fixed half and moving half, cover half be shaped as cone barrel, the top of this cone barrel is to cooperate with dynamic model to form air inlet flange suitable for reading position, cylindrical or other shape, the cone barrel remainder is identical with all the other position shapes of air inlet, and dynamic model is the spheroid of a band circular arc, and circular arc is consistent with the flange of air inlet upper oral part.
Can be divided into two parts for its shape of cover half, top is divided into formation air inlet top flange part, the lower part is identical with the remainder of air inlet, therefore cover half top can be cylindrical shape or other shape, as long as this shape can form the flange position on air inlet top by dynamic model spinning.
The utility model is used for the technology of blower fan metal air inlet processing, comprises the steps:
(1) blanking one flitch;
(2) make mold with cover half, flitch is processed into the cone barrel workpiece;
(3) shed cover half, the upper oral part of cone barrel workpiece is needed the part annealing of flange;
(4) upper oral part with cone barrel leans on a dynamic model upper overturning;
(5) edging, inloading part forms air inlet;
The processing mold that is combined to form air inlet of fixed half and moving half, so the corresponding size of the shape of cover half and dynamic model and size and air inlet is corresponding.So only adopting dynamic model is after flange is made, and dynamic model can be taken away, and workpiece is released.
The formation of cone barrel workpiece preferably under cover half rotates spinning finish.
During use, cover half can be fixed on and drive the cover half rotation on the lathe, flitch is fixed on the bottom surface of cover half, by known spinning wheel or spinning machine flitch is carried out spinning until forming cone barrel.Upper oral part to the cone barrel workpiece that forms carries out annealing in process then, to reduce its stress.The circular arc spheroid of dynamic model is embedded with bearing, and spheroid is connected with the outer ring of bearing, and the inner ring of bearing is fixed on the support bar.The fixedly connected mode of support bar is to drive the motion of dynamic model advance and retreat.When needs carried out flange, support bar drove the upper oral part of spheroid near cone barrel, makes the upper oral part of cone barrel consistent with the spheroid circular arc of dynamic model by spinning wheel.When spinning, spinning wheel rotates, and spheroid also rotates passively thereupon, can finish the flange action so better.After flange is finished, carry out the edging finishing, dynamic model withdraws from then.
Advantage of the present utility model:
1, mould is fairly simple, operate more convenient, saved equipment investment and mould the investment, common mechanical factory all can process.
2, the air inlet that obtains does not have weld seam, projection, fold, phenomenon of rupture can not occur, and surface quality obviously improves.
3, save raw material more than one times.
4, work efficiency improves, and can reach more than 4 times.

Among the figure: 1 cover half, 2 dynamic models, 3 spinning wheels, 4 base plates, 5 spheroids, 6 bearings, 7 steady pins, 8 support bars, 9 pressing plates
The specific embodiment
As Fig. 6, be the contour structures of blower fan metal air inlet.
Processing technology is:
1, blanking, according to the size of air inlet, blanking one circular flitch;
2, flitch is fixed on the bottom surface of cover half, cover half fixedly drives cover half and flitch rotation on the lathe, with spinning wheel 3 flitch is spun into the cone barrel workpiece;
3, the cone barrel workpiece is unloaded from cover half, be installed on the base plate 4, annealing in process is carried out at the cylinder position of upper oral part;
4, as Fig. 3, the cylindric position of the upper oral part of cone barrel is against on the dynamic model 2, make this position flange with spinning wheel 3 equally;
5, after flange is finished, carry out the edging finishing, dynamic model leaves workpiece, unloads the workpiece of making and is air inlet.
Cover half be shaped as cone barrel, the top of this cone barrel is cylindrical, and the workpiece that cylindrical shape forms is the workpiece that needs flange, and the remainder shape of remainder and air inlet adapts to, dynamic model is the spheroid of a band circular arc, and circular arc is consistent with the flange of air inlet upper oral part.The spheroid of dynamic model is embedded with bearing 6, and spheroid is connected with the outer ring of bearing, and the inner ring of bearing is fixed on the support bar 8.Can firm better spheroid in the spheroid by pressing plate 9 and steady pin 7.The fixedly connected mode of support bar can be any mode of all knowing that can drive the motion of dynamic model advance and retreat.
