It is low, it is difficult often to meet requirement；In addition, during metal winding pipe bending, since the wall compression deformation of bending part is serious, by
Power is uneven, causes intraluminal passage to be crowded flat and be unable to normal use.
The content of the invention
The purpose of the present invention is overcome the deficiencies in the prior art, and a kind of punching press swan neck system is provided, it solves tradition
Manual bending steel pipe be difficult to control bending angle and dynamics, be easy to cause intraluminal passage and be crowded flat and be unable to normal use
The problem of.
The technical scheme is that：Punching press swan neck system, including circular arc external mold, circular arc internal model, jack, sliding block, cunning
Rail and bearing；Circular arc external mold is fixed on bearing in fan cylindricality, its lower face, its inner arc face is equipped with the arc groove of indent
B；Circular arc internal model is fixed on sliding block in fan cylindricality, its lower face, its outer arc face is equipped with the arc groove A of indent, arc
The arc groove B of groove A face circular arc external molds, its another side end face opposite with outer arc face are piston rod joint face；Jack
It is fixed on bearing, its piston rod protrudes horizontally up, and is connected on the piston rod joint face of circular arc internal model；Sliding block is movably arranged on
On slide；Slide is fixedly mounted on bearing；
When circular arc internal model, which is moved to, to be contacted with circular arc external mold, the arc groove A of circular arc internal model splices with the arc groove B of circular arc external mold
Close up to form steel pipe sizing chamber.
Further technical solution is the present invention：It further includes lengthening mould；Lengthen mould to be fixed on bearing, and be located at circular arc
The end of external mold, its inner face are equipped with the straight trough for the non-bending segment of steel pipe of shaping, and straight trough is with the arc groove B's of circular arc external mold
End docking coincide.
Further technical solution is the present invention：The arc groove A of circular arc internal model, the arc groove B of circular arc external mold, lengthen mould
Straight trough be section semicircular in shape groove.
Technical solution of the invention further is：Circular arc internal model, circular arc external mold and lengthening mould are bolted
On bearing.
The present invention has the following advantages that compared with prior art：
1st, starting jack closes up circular arc internal model and circular arc external mold, you can realize the bending of straight steel pipe, it is easy to operate.
2nd, in press bending process, the arc groove A of circular arc internal model, the arc groove B of circular arc external mold and straight steel pipe outer wall come into full contact with,
Effectively prevent bending part from occurring the phenomenon being locally crushed because of unbalance stress.
3rd, by replacing, circular arc internal model and circular arc external mold are suitable for different angle, the steel pipe of various outer diameter is bent.
Below in conjunction with figure, the invention will be further described with embodiment.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Fig. 2 is the A-A sectional views of Fig. 1.
Embodiment
Embodiment 1：
As shown in Figure 1, 2, punching press swan neck system, including circular arc external mold 1, circular arc internal model 2, jack 3, sliding block 4, slide 5 and branch
Seat 6.
