Be further used as the improvement of technical solutions of the utility model, be connected and be provided with pre-sealed ager with pre-sealed pressure conduit, be connected and be provided with hole enlargement ager with hole enlargement pressure conduit, be connected and be provided with air bleeding valve with discharge duct.
Be further used as the improvement of technical solutions of the utility model, expand the maximum gauge that an external diameter at body middle part is less than position, seal groove place.
Be further used as the improvement of technical solutions of the utility model, the air inlet of discharge duct is positioned between two seals ring recess.
The beneficial effects of the utility model: this composite bimetal pipe pipe end hydraulic pressure set composite is inserted an expansion body in multiple tube, first pin and expand a body two ends and multiple tube sealing by the pressure of pre-sealed pressure conduit, carry out pipeline by the pressure of hole enlargement pressure conduit afterwards compound, the gas producing in recombination process is discharged by discharge duct, pipeline is compound to carry out pressure release after completing and can carry out the compound of next pipeline, this apparatus structure is simple, and be convenient to the automated production of multiple tube, can effectively enhance productivity.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure schematic diagram.
The specific embodiment
With reference to Fig. 1, the utility model is a kind of composite bimetal pipe pipe end hydraulic pressure set composite, comprise that maximum outside diameter is less than an expansion body 1 of multiple tube 10 internal diameters, expand in a body 1 and be provided with pre-sealed pressure conduit 2, hole enlargement pressure conduit 3 and discharge duct 4, the two ends that are positioned at multiple tube 10 parts on an expansion body 1 are equipped with seal groove 51, in seal groove 51, be provided with sealing ring 5, the delivery port of pre-sealed pressure conduit 2 is positioned at the inner side of sealing ring 5, and the delivery port of hole enlargement pressure conduit 3 is between two seals ring recess 51.
This composite bimetal pipe pipe end hydraulic pressure set composite is inserted an expansion body 1 in multiple tube 10, first seal by a pressure pinning expansion body 1 two ends and the multiple tube 10 of pre-sealed pressure conduit 2, carry out pipeline by the pressure of hole enlargement pressure conduit 3 afterwards compound, the gas producing in recombination process is discharged by discharge duct 4, pipeline is compound to carry out pressure release after completing and can carry out the compound of next pipeline, this apparatus structure is simple, and is convenient to the automated production of multiple tube, can effectively enhance productivity.
