Abstract
The utility model discloses a pipeline bending forming die, and belongs to the field of stamping equipment. The pipeline bending forming die comprises an upper die base and a lower die base, wherein the lower die base is connected with a concave die through a pin, a V-type groove is formed in the middle of the concave die, and a first V-type pipeline groove with the cross section being semicircular is formed in the middle of the V-type groove; the upper die base is connected with a convex die through a pin; the convex die in of a V-type structure, and a second V-type pipeline groove is formed in the middle of the convex die and corresponds to the groove. According to the pipeline bending forming die, the concave die and the convex die which are respectively provided with one pipeline groove and matched with each other are adopted for bending and forming pipes, the phenomenon that the pipes deform because of uneven stress in the stamping process is avoided, and the pipeline bending forming die is reasonable in structural design, convenient to use, high in machining efficiency and good in stamping effect.
Description
Technical field
The invention belongs to pressing equipment field, more particularly, relate to a kind of pipeline bend forming die.
Background technology
When pipe fitting is carried out to Bending Processing, common die cannot meet the indeformable requirement of processing, for this reason, need to design a kind of mould of applicable punched pipefitting processing.
Summary of the invention
the problem that 1, will solve
For the above-mentioned problems in the prior art, the invention provides a kind of pipeline bend forming die, it is a kind of pipe fitting bending and harmless mould of being applicable to, reasonable in design, punching press are effective.
2, technical scheme
In order to address the above problem, the technical solution adopted in the present invention is as follows:
A kind of pipeline bend forming die, comprise upper bolster, die shoe, on described die shoe, by pin, be connected with die, the middle part of described die is provided with " V " type groove, and it is semicircular first " V " type pipe-line tank that the middle part of described " V " type groove has cross section; Described upper bolster is connected with punch by pin; Described punch is " V " font structure, and its middle part has second " V " type pipe-line tank corresponding with groove.
Further, the Si Jiaochu of described upper bolster is provided with hanger; The bottom of described die is provided with die backing plate.
Further, described punch is provided with several pilot pins.
3, beneficial effect
Than prior art, beneficial effect of the present invention is:
The present invention adopts the concave-convex mold with pipe-line tank cooperatively interacting to carry out bending and molding to pipe fitting, has avoided pipe fitting unbalance stress when punching press to produce distortion, reasonable in design, easy to use, and working (machining) efficiency is high, and punching press is effective.
