Description
Technical field
The utility model relates to mould pressing apparatus field more particularly to a kind of springback compensation knots for spinning machine core model
Structure.
Background technique
Spinning is a metal forming technology, has the characteristics that small material loss, simple process, is readily produced, especially
It is when shaping cone-shaped product with its original advantage.Existing spinning machine is mostly that plate blank is clipped in mandril and core model
Between, core model is driven by machine tool chief axis, while blank is rotated with core model, stresses on blank with spinning roller, is allowed to generate part
Plastic deformation.Under the feed motion of spinning roller and the rotary motion collective effect of blank, make local plastic deformation step by step
The all surfaces of blank are expanded to, and are tightly attached to core model, complete the rotary pressing processing of blank.Cone-shaped product after mould pressing is universal
There is a problem of that rebound causes final size bigger than normal.
202803825 U of Chinese patent Authorization Notice No. CN, authorized announcement date 2013.03.20, it is entitled " numerical control without
The rebound of mould spinning machine spinning, type face are in machine automatic checkout system ", spinning process can accurately be monitored in machine by disclosing one kind
The system of the characteristic informations such as middle part type face and rebound, but this device still not can solve the cone-shaped product after mould pressing
The problem for causing final size bigger than normal because of rebound.
Utility model content
The purpose of this utility model is to overcome the cone-shaped products after mould pressing in the prior art because springing back problem most
Whole size deficiency bigger than normal provides a kind of springback compensation structure for spinning machine core model, can rebound to cone-shaped product into
Row compensation, meets the requirements its final size.
To achieve the goals above, the utility model uses following technical scheme:
A kind of springback compensation structure for spinning machine core model, including
The end of shaft and skeleton, the shaft is equipped with scratch diskette, and skeleton is surrounded by several shaped bars, shaped bar
The hinged scratch diskette in one end edge, the spacing of shaped bar and shaft by close to scratch diskette to the direction far from scratch diskette gradually
Increase, shaft is equipped with the sliding sleeve that can be moved axially along shaft, be hinged on sliding sleeve and several support correspondingly with shaped bar
Bar, support rod and corresponding shaped bar are hinged；
The skeleton is equipped with several and coaxially arranged forming ring of shaft, and forming ring includes shaping ring body and along forming
Several rod sets that the circumferential direction of ring body is sequentially distributed, rod set are hinged in forming ring body, and rod set and shaped bar correspond, at
Shape bar passes through corresponding rod set.It slides over when being moved in shaft, shaped bar is lifted or put down by support rod, controls entire skeleton
Contraction, forming ring fills up the gap between the circumferentially upper shaped bar of skeleton, makes the cone-shaped product better quality obtained, can revolve
Cone-shaped product is manufactured into the springback capacity at smaller size, after making up tapered formed product when pressing formation, the ruler after final rebound
It is very little to be consistent with actual size.
Preferably, each forming ring is sequentially distributed along the axial direction of shaft, the outer diameter of each forming ring by close to scratch diskette to remote
Direction from scratch diskette is sequentially increased.Forming ring plays a supportive role to skeleton, while when blank is attached on skeleton, forming ring is to base
Material also has forming effect.
Preferably, the sliding sleeve is equipped with locking pin, shaft is equipped with several pin holes, and locking pin is inserted in one of pin
Kong Zhong.For adjusting skeleton to locking sliding sleeve after suitably sized, skeleton is made to keep stablizing.
Preferably, the number of the shaped bar is 4 ~ 20.
Preferably, the number of the forming ring is 3 ~ 12.
The beneficial effects of the utility model are: (1) can control the flexible of skeleton, in mould pressing by moving sliding sleeve
Before adjust skeleton to suitably sized, the springback capacity after compensation cone-shaped product forming, so that the final size of cone-shaped product accords with
It closes and requires；(2) forming ring fills up the gap between the circumferentially upper shaped bar of skeleton, while also playing styling to skeleton, is being spun into
It is indeformable during shape, and forming ring can move on shaped bar with stretching for skeleton, adapt to the life of different cone-shaped products
It produces.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of common spinning machine；
Fig. 2 is the structural schematic diagram of the utility model；
Fig. 3 is the structural schematic diagram of forming ring in the utility model；
Fig. 4 is the enlarged drawing in Fig. 3 at A.
In figure: mandril 1, core model 2, spinning roller 3, blank 4, shaft 5, scratch diskette 51, shaped bar 6, sliding sleeve 7, support rod 71, lock
Rationed marketing 72, pin hole 73, forming ring 8, forming ring body 81, rod set 82.
Specific embodiment
The utility model is further described in the following with reference to the drawings and specific embodiments.
The structure of common spinning machine is as shown in Figure 1, include that mandril 1, core model 2 and spinning roller 3, mandril and core model press from both sides blank 4
In centre, three rotates with machine tool chief axis together, and spinning roller stresses on blank, is allowed to generate the plastic deformation of part, in spinning roller
Under the rotary motion collective effect of feed motion and blank, local plastic deformation is made to expand to whole tables of blank step by step
