Extensively.
The segmentation die mould technique of blower fan wheel cap molding of the present invention, wheel cap one is spliced by four pieces of wheel covers,
Wheel cover is in fan ring-shaped, and along circular arc direction through repeatedly segmentation die mould, wheel cap is spliced into wheel cap two again and again
Shape also reaches requirement, and concrete technology comprises the following steps:
1. by good slab under wheel cover to be formed；
2. the die mould of plate is carried out by casted die mould: be positioned on casted die mould by one side of something of wheel cover, and wheel cover
The justified margin of one end and casted die mould, forcing press work will the part die mould being placed on mould of wheel cover until reaching
Qualified size, then wheel cover is rotated along circular arc direction, forcing press work is by the part pressure being placed on mould of wheel cover
Type is until reaching qualified size, and the rest may be inferred, until monoblock wheel cover die mould is fully completed.
3. the wheel cover splicing composition wheel cap one that four pieces of die moulds complete, wheel cap shapes with wheel cap two splicing again and again.
This technique, by wheel cover and the justified margin of mould, carries out die mould after fixing position, and after die mould, becomes
Wheel cover can be realized the most fixing directly against being combined on down-pressing type face by the part of type, and this mould can be by small-sized
Casted die mould realizes the multistage die mould of large fan wheel cap, is applicable to size and the pressure of close other blower fan wheel caps of shape
Type, applied widely, sufficiently lower the cost of manufacture of mould, shorten the production duration, and die mould is for 3 times under normal conditions
Can complete the die mould of one piece of wheel cover, production efficiency is high.
In above-mentioned segmentation die mould technique:
Described casted die mould includes upper plate, lower shoe, punch insert, die plate insert, and described punch insert is sagging with on die plate insert
Directly being arranged symmetrically with, described punch insert is spliced by some pieces of upper vertical plates, and described die plate insert is spliced by some pieces of lower risers
Forming, the upper die mould face of described punch insert is in the cambered surface being bent upwards, and the down-pressing type face of described die plate insert is reclinate arc
Face, described punch insert is fixed on upper plate, and the outside of described punch insert is provided with on outside and mends plate, described punch insert
Inner side be provided with inner side on mend plate, described die plate insert is fixed on lower shoe, the outside of described die plate insert be provided with outside
Lower benefit plate, the inner side of described die plate insert is provided with under inner side and mends plate.
The design of this casted die mould structure is simple, and Design of Dies volume is little, and punch insert and die plate insert are spelled by some pieces of risers
Connect and form, processing simplicity, mend plate and be used for solid punch core and die plate insert, make sound construction, not only shorten the production duration, reduce
Die cost, and it is fully able to meet the die mould needs of wheel cover, wheel cover can be real with the justified margin of mould
Now position, and after die mould is crossed once, the part of wheel cover die mould bending is stuck in the down-pressing type face of die plate insert, accurate positioning.
In above-mentioned segmentation casted die mould:
Punch insert, die plate insert, upper plate, lower shoe all can be according to the shape independent design of cover plate, outside upper plate is with lower shoe
Shape can determine according to the size of punch insert with die plate insert, and punch insert is fixed by welding on upper plate, and die plate insert is by welding
It is fixed on lower shoe.
Punch insert and die plate insert in the projection of horizontal plane all in fan ring-shaped, it is simple to matched moulds.
Punch insert is spliced by 9 pieces of upper vertical plates and passes through to be welded and fixed, and die plate insert is spliced by 9 pieces of lower risers and is led to
Cross and be welded and fixed.
The present invention compared with prior art has the advantage that
1, the present invention can realize the shaping of large fan wheel cap by a set of little mould, sufficiently lower being fabricated to of mould
This, shorten the production duration.
2, instant invention overcomes large mold single cavity die limited by press tonnage, workbench, the problem of location difficulty, fixed
Level is true, and formed precision is high.
3, the present invention can be according to product design requirement, it is achieved multistage die mould, is applicable to size and close other of shape
The die mould of blower fan wheel cap, applied widely.
4, present invention die mould under normal conditions can complete the die mould of one piece of wheel cover for 3 times, and production efficiency is high.

Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the invention are described further:
As it is shown in figure 1, wheel cap 1 is spliced by four pieces of wheel covers 2, wheel cover 2 is in fan ring-shaped, and along circular arc direction
Through repeatedly segmentation die mould, wheel cap 1 shapes with wheel cap 23 splicing and reaches requirement again, and concrete technology includes following
Step:
1. by 2 times good slabs of wheel cover to be formed；
2. the die mould of plate is carried out by casted die mould: be positioned on casted die mould by one side of something of wheel cover 2, and wheel cover
One end of 2 and the justified margin of casted die mould, forcing press work will take turns the part die mould being placed on mould of cover 2 until reaching
To qualified size, then being rotated along circular arc direction by wheel cover 2, forcing press work is by the portion being placed on mould of wheel cover 2
Dividing potential drop type is until reaching qualified size, and the rest may be inferred, until monoblock wheel cover 2 die mould is fully completed.
3. the wheel cover 2 splicing composition wheel cap 1 that four pieces of die moulds complete, wheel cap 1 shapes with wheel cap 23 splicing again.
This technique, by the justified margin of wheel cover 2 with mould, carries out die mould after fixing position, and after die mould,
Wheel cover 2 can be realized the most fixing directly against being combined on down-pressing type face 11 by the part of molding, and this mould can be by little
The casted die mould of type realizes the multistage die mould of large fan wheel cap, is applicable to size and close other blower fan wheel caps of shape
Die mould, applied widely, sufficiently lower the cost of manufacture of mould, shorten production duration, and die mould 3 times under normal conditions
