Abstract
The invention relates to an integrated mould of a fan impeller. The integrated mould comprises an outer wheel disc mould, a blade mould and an inner wheel disc mould. The integrated mould is characterized in that the blade mould is divided into an upper part and a lower part; the upper part forms a concave part (4) which is recessed to the inside of the blade mould; the concave part (4) is used for placing the inner wheel disc mould; and the lower part is provided with a preformed blade mold cavity (2). As the blade is directly formed on an inner wheel disc and an outer wheel disc of the impeller by the blade mold cavity, the fan impeller manufactured by the mould has the characteristics of high geometrical precision, high integration and corrosive resistance.
Description
Technical field
The present invention relates to a kind of integrated mould, particularly relate to a kind of integrated mould of draught fan impeller.
Background technology
Impeller is the critical piece of centrifugal fan, interior wheel disc, blade, outer wheel disc, consists of.In prior art, the manufacture method of the centrifugal fan impeller of composite is that interior wheel disc, blade, outer wheel disc are processed respectively, and then three is formed it into an integral body by methods such as welding, bonding, riveted joints, and in three junction, carry out suitable reinforcement and process.The impeller forming by described method, it adopts between interior wheel disc, blade, outer wheel disc owing to not being global formation, but purely rely on the interlaminar shear strength existing between three, its adhesive surface is weakness, therefore impeller globality is poor, bonding strength is low, on-stream being easy to thrown off damage, also has the shortcoming that geometric accuracy is not high, thereby causes the problem that fan efficiency is low.
Summary of the invention
The object of this invention is to provide a kind of for the manufacture of draught fan impeller, high, good integrity, the corrosion resistant integrate shaped type mould of geometric accuracy.
For solving the problems of the technologies described above, the present invention takes following technical scheme: a kind of integrated mould of draught fan impeller, comprise outer wheel disc mould, blade mold and interior wheel disc mould, and it is characterized in that: described blade mold is divided into two of upper and lowers part; Described top forms to the recess of described blade mold internal recess, and described recess is used for placing described interior wheel disc mould; Described bottom has preformed blade die cavity.
Because described blade is to be directly formed on the inside and outside wheel disc of impeller by described blade die cavity, therefore by described mould, manufacture draught fan impeller and there is high, good integrity, the corrosion resistant feature of geometric accuracy.
Accompanying drawing explanation
Fig. 1 is the front view of blade mold.
Fig. 2 is the A-A cutaway view of blade mold.
Fig. 3 is the front view of outer wheel disc mould.
Fig. 4 is the A-A cutaway view of outer wheel disc mould.
The specific embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is elaborated.
Fig. 1-2 shows the structure of the blade mold of mould in the present invention, and Fig. 3-4 show the structure of outer wheel disc mould.
As Figure 1-4, the mould in the present invention comprises outer wheel disc mould, blade mold and interior wheel disc mould (not shown).
Described blade mold is a cylinder, and it is divided into two of upper and lowers part; Described top for that form by endless member 1, to the recess 4 of described blade mold internal recess, described recess 4 is for placing described interior wheel disc mould; Described bottom is one to have the solid cylinder of preformed blade die cavity 2, and preferably, described blade die cavity 2 is 10; Top center from described blade die cavity 2 is given prominence to and is formed with an axial region 3 to the inside of described recess 4, and preferably, described axial region 3 is projected into outside described top.
As shown in Figure 3-4, described outer wheel disc mould has a square base Cuo 5, is formed with the die body 6 with reinforcement die cavity 7 on described pedestal 5, and described reinforcement 7 radially distributes; The center of described outer wheel disc mould has the power transmission shaft die cavity 8 that runs through described die body 6 and pedestal 5, and it is used to form the axis hole of impeller, and motor transmission shaft is placed in described axis hole, drives described vane rotary.
Described interior wheel disc mould is placed in described recess 4, wheel disc die cavity in forming between itself and described blade mold.
Between described outer wheel disc mould, blade mold and interior wheel disc mould, by connector, fix formation as a whole, preferably, described connector is bolt.
Claims (5)
