Abstract
The utility model discloses a forging die for producing a fan shaft. The forging die comprises a shaft head forming die, a neck forming die and a heightener, wherein a through hole is formed in the middle of the shaft head forming die; an annular groove is formed outside the neck forming die; a neck forming hole is formed in the middle of the neck forming die; a conical hole is formed at the upper end of the neck forming hole; a through hole is formed at the lower end of the neck forming hole; and a through hole is formed in the middle of the heightener. The forging die is designed by adopting a segmented die so as to facilitate the production and use; by forging the die, the consumption of blanks and the repeated heating frequencies for forging are reduced, so that the cost is reduced; in addition, after forging, the outer surface of the fan shaft is ensured to be very smooth so as to facilitate the subsequent machining and increase the machining efficiency.
Description
Technical field
The utility model relates to a kind of production and uses forging mold, relates in particular to a kind of production blower fan axle and uses forging mold.
Background technology
As everyone knows, blower fan is the abbreviation of gas compression and gas conveying machinery, and the blower fan axle then is the main parts size of blower fan, and when fan starting, the blower fan axle will turn round under at a high speed, so just need the blower fan axle to have good physical and mechanical properties.At present more the blower fan axle adopts to forge and produces, but the blank materials are too much when forging, and needs repeated heating repeatedly, has caused the unnecessary wasting of resources, and it is uneven to forge the blower fan axle appearance of coming out, and influences follow-up mach operating efficiency.
The utility model content
The purpose of the utility model is to provide a kind of production blower fan axle to use forging mold, can improve product quality and production efficiency, and reduce cost.
The purpose of the utility model is to realize through following technical scheme:
A kind of production blower fan axle is used forging mold; Comprise spindle nose mould, neck mould and bed hedgehopping, have through hole in the middle of the said spindle nose mould, said neck mould outside has annular groove; The centre has neck moulding hole; Upper end, said neck moulding hole is a bellmouth, and the lower end is a through hole, has through hole in the middle of the said bed hedgehopping.
Said bed hedgehopping lower end is placed with packing ring.
Said spindle nose mould and neck mould adopt the 5CrMnMo steel.
Said bed hedgehopping adopts 45 steel.
The beneficial effect of the utility model does, said production blower fan axle is used forging mold, and it adopts the segmented die design, is convenient to produce and uses; Forge through mould, the number of times of the use amount that has reduced blank repeated heating when forging, thus reduced cost; And after having guaranteed to forge, blower fan axle outer surface is brighter and cleaner, and the machined after being convenient to has improved mach efficient.
Description of drawings
According to accompanying drawing and embodiment the utility model is done further explain below.
Fig. 1 is that the said production blower fan of the utility model axle is used the forging mold installation diagram.
Among the figure:
1, spindle nose mould, 2, the neck mould, 3, bed hedgehopping, 4, packing ring, 5, annular groove, 6, through hole, 7, bellmouth.
The specific embodiment
As shown in Figure 1, in present embodiment, produce the blower fan axle and use forging mold; Comprise spindle nose mould 1, neck mould 2 and bed hedgehopping 3, have through hole 6 in the middle of the said spindle nose mould 1, said neck mould 2 outsides have the annular groove 5 that is used to lift; The centre has neck moulding hole; Upper end, said neck moulding hole is a bellmouth 7, and the lower end is a through hole 6, has through hole 6 in the middle of the said bed hedgehopping; Said spindle nose mould 1 adopts the 5CrMnMo steel with neck mould 2, and said bed hedgehopping 3 adopts 45 steel.
During production, spindle nose mould 1, neck mould 2 and bed hedgehopping 3 are from top to bottom assemblied successively,, then blank is put into forging mold and forge at bed hedgehopping 3 held packing rings 4.
It adopts the segmented die design to said production blower fan axle with forging mold, is convenient to produce use, and has improved product quality and production efficiency, and has reduced cost.
