Description
Technical field
The present invention relates to fan rotor and flange technology of pressure mounting field, it is especially that a kind of fan rotor is press-fited with flange
Mould.
Background technology
As shown in figure 1, the decomposition texture schematic diagram for fan rotor and flange.When this fan rotor and flange press-fit, lead to
Often press-fited under the impulse force of stamping machine using mould.At present, more common mould is by the upper die and lower die structure of cylindrical shape
Become, integral press mounting effect is undesirable, such as: before press-fiting, because upper die and lower die are made by steel cylinder, overall weight is non-
Often weigh it is more difficult to move upper die and lower die: when upper die and lower die press-fit, impact can be produced on flange, flange is not smooth；Pressure
After installing, upper die and lower die are less susceptible to removal from the workbench below press-connection machine drift.
Content of the invention
The technical problem to be solved in the present invention is to provide one kind and can carry out treating selvedge to flange, and effectively reduces weight, just
In carrying, and the fan rotor easily moving and flange press-fitting mould.
For solving above-mentioned technical problem, the technical scheme that the present invention provides is: includes hollow and is used for press-fiting fan rotor
With the upper die and lower die of flange, the inner hole wall of lower mould is provided with the step for supporting fan rotor, the external diameter of upper mould middle and upper part
Less than the external diameter of upper mould bottom, upper mould lower surface width is more than or equal to flange width, and the external diameter of lower mould middle and lower part is less than down
The external diameter on mould top, lower mould upper surface width is more than or equal to flange width, and upper mould lower surface is additionally provided with prevents end face pressure
Damage the annular groove of flange mounting hole stiffening ring.
Upper mould middle and upper part intersects connection with upper mould bottom by inclined-plane, and lower mould middle and lower part and lower mould top are also by inclined-plane phase
Commissure connects.
After above structure, the present invention has the advantage that the fan rotor of the present invention and flange press-fitting mould are due to upper
The external diameter of mould middle and upper part is less than the external diameter of upper mould bottom, the external diameter of lower mould middle and lower part be less than lower mould top external diameter that is to say, that
Upper die and lower die are connected and composed by two sections that original cylindrical shape is designed to small one and large one, thus makes upper die and lower die
Weight is reduced, and carrying is got up gently a lot, leicht fallen D/A, simultaneously in carrying because there being different two sections of external diameter, compares original
By external diameter identical, one section is constituted, and during carrying, that big section of external diameter will prevent hand from skidding and play position-limiting action, be easy to make power, separately
The bottom of outer upper die and lower die load-bearing and upper thickness keep constant, have ensured weight capacity, have in addition gone up mould lower surface width big
In or be equal to flange width, lower mould upper surface width be more than or equal to flange width, upper mould lower surface and lower mould upper surface
When press-fiting, flange just will not be made to upwarp, width is more than or equal to the lower mould upper surface of flange width and upper mould lower surface
The lower of flange will be pressed against carry out treating selvedge to flange, make flange become very smooth above, and on upper mould lower surface
It is additionally provided with the annular groove preventing end face crushing flange mounting hole stiffening ring, when press-fiting, flange mounting hole stiffening ring is recessed positioned at annular
In groove, the setting of this annular groove protects flange mounting hole stiffening ring directly by upper mould lower surface crushing.
Further, upper mould middle and upper part intersects connection with upper mould bottom by inclined-plane, lower mould middle and lower part and lower mould top
Intersected by inclined-plane and connect, inclined-plane intersects connection makes the straight miner diameter end of bigger diameter end form smooth transition connection, it is to avoid because of wall during shaping
Thick mutation and impact is produced on upper die and lower die.

Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
As illustrated, the fan rotor of the present invention and flange press-fitting mould, including hollow and be used for press-fiting fan rotor 5 and method
Blue 6 upper mould 1 and lower mould 2.The inner hole wall of lower mould 2 is provided with the step 2.4 for supporting fan rotor.
The external diameter of upper mould middle and upper part 1.1 is less than the external diameter of upper mould bottom 1.2, and upper mould lower surface 1.3 width is more than or equal to
Flange 3 width.The external diameter of lower mould middle and lower part 2.1 be less than lower mould top 2.2 external diameter, lower mould upper surface 2.3 width be more than or
Equal to flange 3 width.The annular groove preventing end face crushing flange mounting hole stiffening ring 4 is additionally provided with upper mould lower surface 1.3
1.31.
Upper mould middle and upper part 1.1 intersects connection with upper mould bottom 1.2 by inclined-plane, lower mould middle and lower part 2.1 and lower mould top 2.2
Intersect also by inclined-plane and connect.
Upper die and lower die are made by steel material, by the design of an above-mentioned big outer diameter section and a small outer diameter section,
Largely alleviate weight, save cost simultaneously.In addition the setting of annular groove, by Upper Die-sleeve on fan rotor
When holding and being pressed on flange, can directly by be embossed on flange, placement need not be directed at, because under upper mould in prior art
The not annular groove of end face setting, but the bar extending along upper mould radial direction with flange mounting hole stiffening ring mathematics identical
Shape groove, so by be embossed on flange when, then need to be placed bar-shaped trough alignment flange installing hole stiffening ring,
Position slightly deflection will not push down flange mounting hole stiffening ring, and the present invention is annular groove because set, directly places.
When press-fiting, first cover upper flange in fan rotor upper end, then the fan rotor being cased with flange be placed in lower mould,
The lower end of fan rotor is supported on the step 2.4 of lower mould endoporus simultaneously, now by Upper Die-sleeve at the upper conical end of fan rotor
On, and so that the upper mould lower surface with annular groove is pressed on flange, now by above-mentioned assemble be integrally placed at stamping machine
Below drift, then start stamping machine, mould on stamping machine drift fast ram, upper punch pressure flange makes flange tightly be sleeved on wind
The lower end that machine rotor is relatively large in diameter.
