Abstract
The invention discloses a bending progressive die for rolling an alloy bush. The bending progressive die comprises an upper die body and a lower die body. The upper die body comprises an upper die body seat, a die handle arranged on the upper portion of the upper die body seat, a workpiece pre-bending upper pressing die set and a workpiece pressing bending upper die set. The workpiece pre-bending upper pressing die set and the workpiece pressing bending upper die set are arranged on the lower portion of the upper die body seat. The lower die body comprises a lower die body seat which is provided with a workpiece pre-bending lower pressing die set and a workpiece pressing bending lower die set. The bending progressive die has the beneficial effects that firstly, the technological process for shaft sleeve machining is simplified, and after the die is improved, the pre-bending and large-bending working procedures are combined into one working procedure, so that one working procedure is reduced; secondly, the cost of shaft sleeve machining is reduced, and due to the fact that an original single-working-procedure die is designed to be the multi-working-procedure progressive die, the work efficiency is improved by one time compared with the original work efficiency; and thirdly, the rejection rate is lowered. A guide pillar is designed for the bending progressive die, so that assembly and adjustment are simpler, and work is more stable.
Description
Technical field
The present invention relates to one and roll mould, especially relate to a kind of bending progressive die rolling alloy bushing。
Background technology
At present, along with the development of modern industry, roll lining and get more and more in the application of machinery industry, but in its course of processing, there is operation more, the factors such as product shaping prescription is high, to manpower, equipment, frock input also bigger。This adds the processing cost of axle sleeve undoubtedly, is unfavorable for the long-run development of enterprise。Devise in this context and the single die that original two procedures, two punch presses, two manpowers just can complete can be designed as multi-station progressive die。And originally the general processing technique of axle sleeve is: blanking-pressure oil groove-rush hasp-pre-bending (curved two)-curved greatly (U-bend is bent)-full circle-extruding-face work, chamfering-cylindrical grinding-test package。
Summary of the invention
It is an object of the invention to provide a kind of bending progressive die rolling alloy bushing, solve in one set of die, be provided with the pre-bending rolling alloy bushing and the mould bended。
The technical solution adopted for the present invention to solve the technical problems is: a kind of bending progressive die rolling alloy bushing, including upper die and lower die, described upper mould includes upper bolster, is arranged on the die shank on upper bolster top, it is arranged on workpiece pre-bending top die group and the upper module of workpiece press-bending of upper bolster bottom, described counterdie includes die shoe, and described die shoe arranges workpiece pre-bending dip mold group and the lower module of workpiece press-bending。
Concrete, described workpiece pre-bending top die group includes the upper pre-bending module being arranged on upper bolster bottom, the bottom of described upper pre-bending module is provided with pre-bending punch briquetting, the described lower module of workpiece press-bending includes the pre-bending die cushion block being arranged on die shoe, the slotted eye of described pre-bending die cushion block arranges ejection block, side guide before the top of pre-bending die cushion block is provided with, described pre-bending die cushion block also sets up guide pillar。
Concrete, the described workpiece upper module that bends includes being arranged on the contiguous block of upper bolster, being arranged on the plug that bends of contiguous block bottom, and the described workpiece lower module that bends includes: press-bending die, is arranged on the outer baffle outside press-bending die, arranges rear side stock guide on the top of press-bending die。
Beneficial effects of the present invention: one is a simplified axle sleeve processing process, after die improvement, unites two into one pre-bending and big curved operation, decreases one procedure。
Two: reducing axle sleeve processing cost, because being designed to original single die for multiple operation progressive die, work efficiency was doubled than originally。
Three: reduce and scrap。Design of Dies guide pillar so that assembling and setting is simpler, works more stable。
Below with reference to drawings and Examples, the present invention is described in detail。

Detailed description of the invention
Embodiment 1, as shown in Figure 1, 2, a kind of bending progressive die rolling alloy bushing, including upper die and lower die, described upper mould includes upper bolster 1, is arranged on the die shank 2 on upper bolster 1 top, being arranged on workpiece pre-bending top die group and the upper module of workpiece press-bending of upper bolster 1 bottom, described counterdie includes die shoe 3, and described die shoe arranges workpiece pre-bending dip mold group and the lower module of workpiece press-bending。
Concrete, described workpiece pre-bending top die group includes the upper pre-bending module 4 being arranged on upper bolster 1 bottom, and the bottom of described upper pre-bending module 4 is provided with pre-bending punch briquetting 5,
The described lower module of workpiece press-bending includes the pre-bending die cushion block 6 being arranged on die shoe 3, the slotted eye of described pre-bending die cushion block 6 arranges ejection block 7, side guide 8 before the top of pre-bending die cushion block 7 is provided with, described pre-bending die cushion block 6 also sets up guide pillar 9。The slotted eye of pre-bending die cushion block 6 also sets up back-moving spring 15.
Concrete, the described workpiece upper module that bends includes being arranged on the contiguous block 10 of upper bolster 1, being arranged on the plug 11 that bends of contiguous block 10 bottom, and the described workpiece lower module that bends includes: press-bending die 12, is arranged on the outer baffle 13 outside press-bending die 12, arranges rear side stock guide 14 on the top of press-bending die 12。
5. pre-bending punch briquetting, 6. pre-bending die cushion block, 7. ejection block, 8. before side guide, 9. guide pillar, 10. contiguous block, 11. bend plug, 12. press-bending dies, 13. outer baffles, stock guide on rear side of 14.。
During Design of Dies, die for fisrt forming being placed on the first station, the second station is bending die。Mould both sides band guide pillar 8, pre-bending punch briquetting 5 upper, pre-bending die cushion block 6 under。Mould is contained on 16 tons of punch presses, after having debugged stroke, made sheet stock is delivered to the first station of progressive die with needle-nose pliers, and plate longitudinal register is two front side guides 8, rear side stock guides 14 being contained in the second station, and lateral register is the location-plate being contained in the first station。After punch press first time punching press, plate completes two bending forming (pre-bending) at the first station, now due to the effect of ejection block in mould, it is parked in ejection block after material forming without being stuck in pre-bending die cushion block 6, when second piece of plate is sent into, plate after first piece of shaping is pushed in the second station press-bending die 12, now plate is longitudinally installed in two pieces of striker plate (scalable after mould, it is suitable for different in width product) block longitudinal register, lateral then spacing by two pieces, left and right location-plate (fine-tuning), after now punch press punching press again, the plate of station two is parked in after completing U-bend song and bends on plug, when plate is fed again into station for the moment, each station plate is sequentially released by the plate of rear feeding, complete stamping。Both ensure that product quality, improve yield simultaneously, save various resource。
Above embodiments is only that the preferred embodiment of the present invention is described; not the scope of the present invention is defined; under the premise designing spirit without departing from the present invention; various deformation that technical scheme is made by this area ordinary skill technical staff and improvement, all should fall in the protection domain that claims of the present invention are determined。
Part that the present invention does not relate to is all same as the prior art maybe can adopt prior art to be realized。
