Abstract
The utility model relates to a coining die for decreasing the inner and outer diameters of outer rings of forgings, comprising a backing plate; a die sleeve is fixed right above the backing plate; the forgings drop out from an inner hole at the lower part of the die sleeve; a coining concave die is embedded in an inner hole at the upper part of the die sleeve; a punch is arranged above the coining concave die; and a feeding guide groove plate is arranged at one side of the upper end of the coining concave die. By increasing the inner and outer diameters of outer rings of bearing blanks, matched production can be carried out on the bearing blanks and inner-ring forgings on a high-speed upsetter; and by using the coining die, the inner and outer diameters of the forgings, which are increased, can be decreased through a press, and then the decreased extruded blanks become required forgings.
Description
Technical field
The utility model belongs to the forging technology field, relates to a kind of shape invariance that keeps forging that is adapted to have, and the pressure-sizing mould that dwindles the inside and outside footpath of forging outer shroud that the inside and outside footpath of the outer shroud of forging is diminished.
Background technology
The taper roll bearing of part model can't be organized cover to forge on the high speed upsetter and produce, and these products have L68149/11, L45449/10 and 32004-32010 series etc.Reason is that hole dimension is too approaching with the maximum outside diameter size of interior ring in outer ring minimum, or even the minimum interior hole dimension of the maximum outside diameter size of interior ring serious offense outer ring.
Original solution is that the two is forged separately respectively; Perhaps it is made disjunctor forging (inner and outer rings is swaged into a blank, through the method that car adds inner and outer rings is separated then); These two kinds of Forging Technologies exist the phenomenon that production efficiency and stock utilization reduce significantly, have caused the rising of production cost.
The utility model content
In order to overcome the above-mentioned shortcoming of prior art, the utility model provides a kind of pressure-sizing mould that can the inside and outside footpath of forging outer shroud be dwindled through pressing equipment.
The utility model solves the technical scheme that its technical problem adopted: a kind of pressure-sizing mould that dwindles the inside and outside footpath of forging outer shroud; Comprise backing plate; Middle part above backing plate is fixed with die sleeve, and forging drops out from the bottom endoporus of die sleeve, in the endoporus of the top of die sleeve, is embedded with the pressure-sizing die; Above the pressure-sizing die, be provided with drift, one side is equipped with the charging guide groove plate in the upper end of pressure-sizing die.
In the inboard of said charging guide groove plate and the pressure-sizing die below the drift, the pressure-sizing base is housed.
Said pressure-sizing die endoporus is a cone-shaped inner hole.
The beneficial effect of the utility model is: adopt the inside and outside footpath of the outer shroud of bearing blank is done greatly; Make it the explained hereafter that can on the high speed upsetter, form a complete production network with interior ring rolling spare; Use this pressure-sizing mould; Can dwindle through forcing press the forging that has done greatly in this inside and outside footpath with the inside and outside footpath of forging, the extruded stock after dwindling just become needed product forging.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-drift, 2-pressure-sizing base, 3-charging guide groove plate, 4-die sleeve, 5-forging, 6-pressure-sizing die, 7-backing plate.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Referring to Fig. 1; A kind of pressure-sizing mould that dwindles the inside and outside footpath of forging outer shroud comprises backing plate 7, and the middle part above backing plate 7 is fixed with die sleeve 4; Forging 5 drops out from the bottom endoporus of die sleeve 4; In the endoporus of the top of die sleeve 4, be embedded with pressure-sizing die 6, above pressure-sizing die 6, be provided with drift 1, a side is equipped with charging guide groove plate 3 in the upper end of pressure-sizing die 6; In the inboard of charging guide groove plate 3 and the pressure-sizing die 6 below the drift, pressure-sizing base 2 is housed.
During practical implementation; The said pressure-sizing mould of the utility model is installed on the forcing press, pressure-sizing base 2 is imported in the pressure-sizing die 6, when drift 1 (punch) is descending through charging guide groove plate 3; Force pressure-sizing base 2 to pass through from pressure-sizing die 6 endoporus of band tapering; Make pressure-sizing base 2 reduced diameter, endoporus is also corresponding to be dwindled, and the pressure-sizing base 2 after dwindling has just become needed product forging 5.The utlity model has advantage simple in structure, convenient disassembly, when changing kind, only need to change drift 1, charging guide groove plate 3 and pressure-sizing die 6 and get final product.
Claims (3)
1. pressure-sizing mould that dwindles the inside and outside footpath of forging outer shroud; Comprise backing plate; It is characterized in that: the middle part above backing plate is fixed with die sleeve, and forging drops out from the bottom endoporus of die sleeve, in the endoporus of the top of die sleeve, is embedded with the pressure-sizing die; Above the pressure-sizing die, be provided with drift, one side is equipped with the charging guide groove plate in the upper end of pressure-sizing die.
2. dwindle the pressure-sizing mould in the inside and outside footpath of forging outer shroud according to claim 1, it is characterized in that: in the inboard of said charging guide groove plate and the pressure-sizing die below the drift, the pressure-sizing base is housed.
3. dwindle the pressure-sizing mould in the inside and outside footpath of forging outer shroud according to claim 1, it is characterized in that: said pressure-sizing die endoporus is a cone-shaped inner hole.
