Dynamic production line can parallel lines transmission, to overcome bulky pressing pedestal to avoid and mobile disadvantage.
In addition, in the necking die involved in the application, it is preferable that lower die includes that lower slider and the first tooth are sliding
Seat, the first tooth slide are mounted on lower slider, and mold tooth is mounted on the first tooth slide.
In addition, in the necking die involved in the application, it is preferable that upper die includes that upper saddle and the second tooth are sliding
Seat, the second tooth slide are mounted on upper saddle, are cooperated with the first tooth slide, and mold tooth is mounted on the second tooth slide
On.
In addition, in the necking die involved in the application, it is preferable that further include being separately mounted to lower die and upper die
On tooth backplate, for stopping mold tooth to be detached from from lower die and the upper die.
In the necking die involved in the application, tooth backplate is set, can both have been guaranteed steady when mold tooth works
It is qualitative, it is also easily removable, is conveniently replaceable.
In addition, in the necking die involved in the application, it is preferable that laminating mechanism includes pressing oil cylinder.

Specific embodiment
Hereinafter, the preferred embodiment of the application is described in detail with reference made to the accompanying drawings.In the following description, for identical
Component assigns identical symbol, and the repetitive description thereof will be omitted.Scheme in addition, attached drawing is only schematical, the mutual size of component
Ratio or the shape of component can be with actual difference.
Fig. 1 a shows the structural schematic diagram of necking die involved by the application specific embodiment.Fig. 1 b shows this Shen
Please upper die and lower die involved by specific embodiment structural schematic diagram.Fig. 1 c shows the application specific embodiment institute
It is related to the structural schematic diagram of necking die stitching state.
As shown in Fig. 1 a, Fig. 1 b and Fig. 1 c, necking die 01 involved in the application specific embodiment includes pressing base
Body 10, laminating mechanism 20, upper die 30, lower die 40, mold tooth 50 and tooth backplate 60.Laminating mechanism 20 and lower die 40
It is mounted on pressing pedestal 10, upper die 30 is mounted on the top of laminating mechanism 20, can cooperate with lower die 40 and carry out necking
Operation.Mold tooth 50 is mounted on upper die 30 and lower die 40.Tooth backplate 60 is separately mounted to upper die 30 and pushes
On mould 40, stop to prevent the disengaging of mold tooth 50, if remove tooth backplate 60 can more preferable different model mold tooth
50.When tooth backplate 60 is installed, for example by two screw installations, it can be positioned by semicircle, it is easy to operate.
Pressing pedestal 10 includes that pedestal 10a, two side arm 10b and crossbeam 10c, two side arm 10b are mounted on pedestal 10a
On, crossbeam 10c is then crossed on side wall 10b.Laminating mechanism 20 is arranged in crossbeam 10c, and laminating mechanism 20 can be realized as pressing oil
Cylinder.
Upper die 30 includes that upper saddle 30a and the second tooth slide 30b, the second tooth slide 30b is mounted on upper saddle 30a
