Abstract
The utility model discloses an internal circlip sleeved row continuous mould which comprises an upper mould base, a lower mould base and a driving mechanism, wherein multistage grading stamping moulds are arranged on the continuous mould; the driving mechanism is in driving connection with the stamping moulds; and a stamping mould with an opposite opening direction is sleeved between two adjacent stamping moulds in each row of stamping moulds. The internal circlip sleeved row continuous mould disclosed by the utility model has a simple structure, the stock utilization is increased and the edge of the produced internal circlip is smooth.
Description
Technical field
The utility model relates to back-up ring processing technique field, relates in particular to a kind of hole shield ring sleeve and arranges the 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.As shown in Figure 1, it is progressively to excise rim charge that existing hole is arranged as single and processing technology with back-up ring, finally goes out part.According to above-mentioned processing technology, carry out in process, because hole is arranged as loose with back-up ring 3 three, make stock utilization low, simultaneously, 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, not only affecting outward appearance also wastes 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 hole shield ring sleeve and arrange the progressive die, the making processing for hole with back-up ring, it is simple in structure, has improved stock utilization, and the hole producing is smooth with back-up ring limit portion.
A kind of hole shield ring sleeve the utility model proposes is arranged the progressive die, comprise upper bolster, die shoe, driving mechanism, on the described progressive die, be provided with the grading diel of multistation, described driving mechanism drives and connects described diel, is socketed with a described diel that opening direction is contrary in the described diel of every row between adjacent two described diels.
Preferably, on the described progressive die, be provided with the described diel of two rows.
Preferably, described diel adopts SKD12 material to make, 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 multiple pins for fixed punch compression mould.
In the utility model, drive diel to carry out punch forming make hole 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 material; By employing, overlap row's mode and arrange diel, improved the layout density of diel, thereby further promoted stock utilization; Meanwhile, adopt continuous stamping to substitute segmental resection, made the hole that processing obtains use back-up ring limit portion without machined trace, smooth and easy smooth.
Accompanying drawing explanation
Fig. 1 is the Layout of prior art mesopore back-up ring;
Fig. 2 is the structural representation under a kind of hole shield ring sleeve row progressive die duty the utility model proposes.
The specific embodiment
As shown in Figure 2, Fig. 2 is the structural representation under a kind of hole shield ring sleeve row progressive die duty the utility model proposes.
With reference to Fig. 2, a kind of hole shield ring sleeve the utility model proposes is arranged the progressive die, comprise upper bolster, die shoe, driving mechanism, on the progressive die, be provided with the grading diel of multistation, driving mechanism drives and connects diel, in every row punching mould, between adjacent two diels, is socketed with a diel that opening direction is contrary.
In specific design process, on the progressive die, be provided with two row punching moulds, thereby further improve stock utilization.
In the present embodiment, diel adopts SKD12 material to make, 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 SKD12 material to make diel, 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 overall 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 of balance upper bolster and die shoe, upper bolster and die shoe are respectively equipped with multiple pins 2 for fixed punch compression mould; By being set, lead can improve the stability in stamping-out process.
In the utility model, by driving mechanism, drive diel to carry out punch forming and make back-up ring 1 for hole, by adopting the grading diel of multistation, a blanking, has improved the layout density of diel, has significantly improved the utilization rate of material; By employing, overlap row's mode and arrange diel, improved the layout density of diel, thereby further promoted stock utilization; Meanwhile, adopt continuous stamping to substitute segmental resection, made the hole that processing obtains use back-up ring limit portion 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; any be familiar with those skilled in the art the utility model disclose technical scope in; 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.
