Abstract
The utility model discloses a small-port retaining ring continuous die, which comprises an upper die base, a lower die base and a driving mechanism, wherein the continuous die is provided with a punching die with a plurality of working station stages, and the driving mechanism is connected with the punching die in a driving way. The small-port retaining ring continuous die has the advantages that the structure is simple, the utilization rate of material is improved, and the edge of the produced small-port retaining ring is smooth.
Description
Technical field
The utility model relates to back-up ring processing technique field, relates in particular to a kind of osculum back-up ring progressive die.
Background technology
The Main Function of back-up ring is the cast parts that are fastened on axle, can prevent from being contained in other part plaies on axle, belongs to a kind of securing member, is conventional machine components.Existing osculum technology for processing retainer ring is progressively to excise rim charge, finally goes out part.According to above-mentioned processing technology, carry out in process, mould and die accuracy improves in any case, all can have the vestige that connects cutter, and scrap (bridge) surplus is many at the joining place of front and back work step, and not only affecting outward appearance also wastes sheet material, and also has certain quality risk.
Utility model content
In order to solve the technical problem existing in background technology, the utility model proposes a kind of osculum back-up ring progressive die, for the making processing of osculum back-up ring, it is simple in structure, has improved availability ratio of the armor plate, and the osculum back-up ring limit portion producing is smooth.
A kind of osculum back-up ring progressive die the utility model proposes, comprises upper bolster, die shoe, driving mechanism, is provided with the grading diel of multistation on the described progressive die, and described driving mechanism drives and connects described diel.
Preferably, described diel adopts SKD12 board making, and the case hardness of described diel is that 2200～3600HV, surface smoothness are less than Ra0.2.
Preferably, the shut height of described diel equates.
Preferably, the feeding line height of described diel is consistent.
Preferably, described diel comprise blanking punch that stamping-out is used and with described blanking punch to the punching and blanking die coordinating, described punching and blanking die is fixed on described die shoe, described blanking punch is arranged on described upper bolster.
Preferably, be provided with the guide pillar of upper bolster and described die shoe described in balance between described upper bolster and described die shoe, described upper bolster and described die shoe are respectively equipped with a plurality of pins for fixed punch compression mould.
In the utility model, drive diel to carry out punch forming make osculum back-up ring by driving mechanism, by adopting the grading diel of multistation, a blanking, has improved the layout density of diel, has significantly improved the utilization rate of sheet material; Meanwhile, adopt continuous stamping to substitute segmental resection, made the osculum back-up ring limit portion that obtains of processing without machined trace, smooth and easy smooth.
Accompanying drawing explanation
Fig. 1 is the structural representation under a kind of osculum back-up ring progressive die duty the utility model proposes.
The specific embodiment
As shown in Figure 1, Fig. 1 is the structural representation under a kind of osculum back-up ring progressive die duty the utility model proposes.
With reference to Fig. 1, a kind of osculum back-up ring progressive die the utility model proposes, comprises upper bolster, die shoe, driving mechanism, is provided with the grading diel of multistation on the progressive die, and driving mechanism drives and connects diel.
In the present embodiment, diel adopts SKD12 board making, and the case hardness of diel is that 3000HV, surface smoothness are Ra0.1; The shut height of diel equate and feeding line height consistent; Adopt the diel of SKD12 board making, make diel not only have fine intensity, hardness, the toughness also simultaneously having possessed, can meet the condition of a stamping-out and greatly improved the service life of mould; The shut height of diel equate and feeding line height consistent, make whole punching press neat, and layout is convenient.
In specific design process, diel comprise blanking punch that stamping-out is used and with blanking punch to the punching and blanking die coordinating, punching and blanking die is fixed on die shoe, blanking punch is arranged on upper bolster.
In specific design process, between upper bolster and die shoe, be provided with the guide pillar 2 of balance upper bolster and die shoe, upper bolster and die shoe are respectively equipped with a plurality of pins 3 for fixed punch compression mould; By being set, lead can improve the stability in stamping-out process.
In the present embodiment, drive diel to carry out punch forming make osculum back-up ring by driving mechanism, by adopting the grading diel of multistation, a blanking, has improved the layout density of diel, has significantly improved the utilization rate of sheet material 1; Meanwhile, adopt continuous stamping to substitute segmental resection, made the osculum back-up ring limit portion that obtains of processing without machined trace, smooth and easy smooth.
The above; it is only the preferably specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; according to the technical solution of the utility model and utility model design thereof, be equal to replacement or changed, within all should being encompassed in protection domain of the present utility model.
