No welding seams exist on the obtained wind inlet of the fan by the technology and the mould of the present invention, the phenomena of prominence, corrugation and rupture can not occur, and the surface quality is obviously improved. The present invention has the advantages of simple mould and convenient operation; equipment investment and mould investment are saved, and the metallic wind inlet of a fan can be processed by common mechanical factories; the raw material can be saved by more than one time, and the work efficiency can be improved by more than four times.
Description
Technical field
The present invention relates to a kind of blower fan metal air inlet processing technology and equipment thereof.
Background technology
Blower fan metal air inlet as shown in Figure 6, 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 by this invention provides blower fan metal air inlet processing technology and processing unit (plant) thereof, improves part quality, and material consumption is saved in saving equipment and frock investment.
Blower fan metal air inlet processing technology of the present invention is characterized in that comprising 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 the cone barrel workpiece 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 above-mentioned cone barrel workpiece preferably under cover half rotates spinning finish.
Processing unit (plant) of the present invention mainly comprises a cover pattern, pattern is made up of fixed half and moving half, cover half be shaped as cone barrel, cylindrical or other shape in the top of this cone barrel, the cone barrel remainder is identical with all the other position shapes of air inlet, 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.
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 the cone barrel workpiece, makes the upper oral part of cone barrel workpiece 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 was finished, dynamic model withdrawed from, and carried out the edging finishing then.
Advantage of the present invention:
1, part does not have weld seam, projection, fold, phenomenon of rupture can not occur, and surface quality obviously improves.
2, mould is fairly simple, operate more convenient, saved equipment investment and mould the investment, common mechanical factory all can process.
3, save raw material more than one times.
4, work efficiency improves, and can reach more than 4 times.

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 workpiece 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.
