Description
Technical field
The utility model is related to a kind of bulging devices, and in particular to a kind of bulging device of internal high pressure forming pipe fitting belongs to
Metal product technical field.
Background technology
Domestic automobile industry is always using the special-shaped tubing zero of the processes such as hot forming, welding, shaping, surface treatment manufacture
Part, performance and workmanship are significantly lower than products such as moral, Great Britain and Americas, and such processing technology is not only complicated, and efficiency is low, and most
The unstable product quality of final shaping unit, short life.
Hydroforming technology be the U.S., the German utility model nineties in last century novel forming technique, navigating at first
It is applied in the manufacture of the parts such as its satellite launcher, Airplane's Oil Way system, and extends to the row such as automobile, rail vehicle rapidly
Industry solves " split heat punching+welding+school shape " technology manufacture pipe（Shell）Class part performance shakiness, precision deficiency, inefficiency etc.
Technique bottleneck problem, internal high pressure forming technique make that part structure refinement, grain flow are controllable, performance is significantly improved, and are to become
Diameter becomes that wall thickness abnormal shape shell type component is high-quality, most effective technology of efficient, low consumption manufacture forming, be it is current it is international into
Shape research and application development new technology the most rapid.
The critical process of the pipe fitting of internal high pressure forming is hydroforming, and hydroforming is to be passed through height to inside pipe fitting
Calm the anger body, be expanded into using mold in tube surface it is variously-shaped, be finally made suitable for various occasions internal high pressure forming it is different
Type pipe fitting.Conventional hydroforming device is due to being often passed through high pressure gas, it is easy to and it damages, needs to be replaced frequently,
Cause cost higher；Pipe fitting bulging can only be gone out fixed shape by bulging device previous simultaneously, lead to manufactured shape tube structure
It is single.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, seal head need to be individually replaced by providing a kind of, reduce cost
Internal high pressure forming pipe fitting bulging device.
What the purpose of this utility model was realized in：
A kind of bulging device of internal high pressure forming pipe fitting, it includes a connecting rod, and one end and the end cap of connecting rod are fixed,
The other end is connected through a screw thread with seal head, wherein the external setting external screw thread of connecting rod, the inner wall setting internal thread of seal head,
The surface of the connecting rod opens up air-filled pore, and air-filled pore is connect with external high-pressure air pipe, in the connecting rod and seal head
Between be provided in the axial direction with central through hole, central through hole one end is connected with air-filled pore, and the other end leads to pipe fitting from the end of seal head
Interior, the outside of this outer end cap is also connect with the piston rod of hydraulic cylinder, is entered in pipe fitting by Hydraulic Cylinder seal head, the pipe
Part is placed in expanding die, which includes mold and lower mold, and mold and lower mold clamp pipe fitting, upper mold
Have, the surface of lower mold is provided with multiple recessed holes.
Compared with prior art, the beneficial effects of the utility model are：
The bulging device of the utility model internal high pressure forming pipe fitting is by setting dismountable seal head, due to only sealing
Head is stretched into pipe fitting, and the part outside seal head is hardly damaged, and screw thread dismounting is only needed just to be convenient for changing after seal head damage, is dropped
Low cost；In addition bulging device opens up recessed hole on upper/lower die surface, and recessed hole is made variously-shaped, is used to form pipe fitting
Bulging space, inside pipe fitting can form the scheduled shape of recessed hole after being passed through high pressure gas in bulging space, just can obtain
To the shape tube finished product of various structures.
