Specific implementation mode
It need to can by multi-drawing when in order to solve the deep parabola rotary body tensioning member of production existing in the prior art
Molding, the higher problem of cost provide a kind of stretching die, and concrete thought is as follows：Including top plate, at least two connecting poles, cavity plate,
Punch-pin, blank holder and bottom plate；Punch-pin includes integrally formed connecting pin and moulding end, and connecting pin is fixedly connected on bottom plate,
Blank holder is sheathed on the periphery wall of connecting pin, and moulding end forms parabolic shape cambered surface towards the gradual undergauge in top plate direction；Cavity plate with
Top plate by can elastic telescopic the connection of at least two connecting poles, cavity plate center offers the opening with connecting pin shape adaptation,
When treating tensioning member and being stretched, cavity plate is used to moved towards blank holder until abutting with to being sheathed on moulding end with blank holder
On part to be tensioned stretched.Stretching die provided by the utility model can effectively reduce production process, disposably stretch shape
At deep parabola rotary body tensioning member, reduce the cost.
As shown in Figure 1, the utility model provides a kind of stretching die, parabola rotary body tensioning member is formed for stretching,
Including top plate 1, at least two connecting poles 2, cavity plate 3, punch-pin 4, blank holder 5 and bottom plate 6, be provided with two companies in the present embodiment
Connect column 2；The punch-pin 4 includes integrally formed connecting pin 41 and moulding end 42, and the connecting pin 41 is fixedly connected on the bottom
On plate 6, the blank holder 5 is sheathed on the periphery wall of the connecting pin 41, and the moulding end 42 is gradual towards 1 direction of the top plate
Undergauge forms parabolic shape cambered surface；The cavity plate 3 and the top plate 1 are by can at least two connecting poles 2 described in elastic telescopic
Connection, 3 center of the cavity plate offers the opening 31 with 41 shape adaptation of the connecting pin, is stretched when treating tensioning member
When, the cavity plate 3 is used to moved towards the blank holder 5 until abutting with to being sheathed on the moulding end with the blank holder 5
Part to be tensioned on 42 is stretched.
In conjunction with shown in Fig. 1 and Fig. 2, in the present embodiment, top plate 1 and bottom plate 6 are all rounded, can also in other embodiment
