Abstract
The utility model discloses a bearing roller stamping three-combination base mould, which is mainly composed of an upper base, a lower base and an alloy moulding core, wherein the alloy moulding core is arranged in the center of the upper base, and the upper end face of the alloy moulding core is level with that of the upper base and the lower end face of the alloy moulding core is level with that of the upper base; the lower end face of the upper base tightly leans against the upper end face of the lower base; through push-out holes are formed in the centers of the upper base and the lower base; and the distance between two side walls of the upper base and the lower base is equal or is gradually increased from top to bottom. According to the utility model, since a base is divided into an upper part and a lower part from the bottom of the alloy moulding core, the phenomenon of base breakage caused by sharp corner existing at a juncture position of the moulding core and the base in the prior art can be prevented, and the alloy moulding core is more easily replaced after being worn and the upper base and the lower base do not need to be replaced, so that the service life is prolonged, the cost is saved and the working efficiency is improved.
Description
Technical field
The utility model relates to field of machining, and a kind of bearing makes up base moulds with roller punching press three specifically.
Background technology
Roller bearing is a kind of as bearing, be widely used in the fields such as various big machineries, vehicle, roller in the roller bearing utilizes pressing to produce in the prior art, then the shape and size of mould and roller to be processed coupling use drift and die that material is squeezed into predetermined shape.
Roller die of the prior art is made of middle mould and base etc., and base is generally two style structure, and one is base housing, and one is forming core.Namely be mounted to core in base, the bottom position that contacts with base at forming core is provided with grinding undercut; The effect of grinding undercut be for guarantee housing dress up cored hole and there is not fillet in the baseplane, thereby make forming core can be fully and the plane fit tightly.But the existence of grinding undercut has caused the appearance of wedge angle, and when heat treatment process, because the existence of wedge angle causes stress to concentrate easily, it is very thin that housing cracks crackle easily, only has in use housing to rupture and just knows.The housing of fracture has caused whole base to scrap.
The utility model content
Because concentrating, the heat treatment stress that the grinding undercut wedge angle produces causes the whole problem of damaging of base for solving in the prior art, the utility model provides a kind of bearing to make up base moulds with roller punching press three, this mould adopts split-type structural, the generation of effectively having avoided stress to concentrate has prolonged service life.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of bearing makes up base moulds with roller punching press three, mainly formed by upper bed-plate, lower bottom base and alloy forming core three parts, wherein, the alloy forming core is arranged on the center of upper bed-plate, and both upper and lower end faces are mutually concordant, the lower surface of upper bed-plate and the upper surface of lower bottom base are close to, the center of upper bed-plate and lower bottom base is provided with the introduction hole of perforation, and the distance between upper bed-plate and the lower bottom base two side equates or from top to bottom gradually increase.
In the utility model, the effect of introduction hole is that the roller after the moulding is released from the alloy forming in-core; Distance between upper bed-plate and the lower bottom base two side increases from top to bottom gradually, has not only guaranteed the stability of base when stamping roller, also can reduce the impulsive force that base is subject to simultaneously, prolongs the service life of base.
Beneficial effect: the utility model is divided into up and down two parts from the bottom of alloy forming core with base, not only avoided the base phenomenon of rupture that forming core and base junction exist the wedge angle to cause in the prior art, and the easier replacing of energy after the wearing and tearing of alloy forming core, the top and the bottom base then need not be changed, prolonged service life, provide cost savings, improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of existing two combination bearings with roller punching press base mould;
Reference numeral: 1, introduction hole, 2, lower bottom base, 3, upper bed-plate, 4, the alloy forming core.
The specific embodiment
As shown in the figure, a kind of bearing makes up base moulds with roller punching press three, mainly formed by upper bed-plate 3, lower bottom base 2 and alloy forming core 4 three parts, wherein, alloy forming core 4 is arranged on the center of upper bed-plate 3, and both upper and lower end faces are mutually concordant, and the upper surface of the lower surface of upper bed-plate 3 and lower bottom base 2 is close to, the center of upper bed-plate 3 and lower bottom base 2 is provided with the introduction hole 1 of perforation, and the distance between upper bed-plate 3 and lower bottom base 2 two sides equates or from top to bottom gradually increase.
In the utility model, first alloy forming core 4 is installed in the upper bed-plate 3, then upper bed-plate 3 and lower bottom base 2 being packed into middle mould just can be used for processing roller in the special overcoat.
