The specific embodiment
In order to overcome the swollen machine drawing mechanism of existing composite bimetal pipe high pressure liquid complicated in mechanical structure, the discharging process coordinating is poor, control accuracy is low, discharge system not only cost is high, and production process is safeguarded the very problem of inconvenience,, the present embodiment provides the composite bimetal pipe high pressure liquid shown in a kind of Fig. 1,2 swollen machine drawing mechanism, comprises left swollen mould 2, stirring arm 3, right swollen mould 4, major axis 5, fixed mandril 6 and hydraulic cylinder 7; The right-hand member of left swollen mould 2 and right swollen mould 4 is arranged on major axis 5; Stirring arm 3 is the bend arm identical with the inner surface radius of the swollen mould 2 in a left side, is arranged on the end face of the swollen mould 2 in this left side, and the left end top 8 of this stirring arm 3 is hinged with this end face; Hydraulic cylinder 7 is placed in the left side of left swollen mould 2, and its end cap 9 is hinged with ground, and the top 11 of its piston rod 10 is hinged with the left side of the bottom surface 12 of left swollen mould 2; Fixed mandril 6 is fixed on before this end face and is placed between the below, left side and hydraulic cylinder 7 of stirring arm 3, when the swollen mould 2 in a left side under the driving of hydraulic cylinder 7 to left down in switching process pushing tow live stirring arm 3.
By Fig. 2, be not difficult to find out, in the present embodiment, the left end top 8 of stirring arm 3 is hinged with the inside top 13 of left swollen mould 2 end faces, and thus, stirring arm 3 can rotate flexibly.Discharging stand 1 is positioned at left swollen mould 2 left sides, and it has certain gradient, and discharging steel pipe 14 can be rolled forward under Gravitative Loads; Fixed mandril 6 is positioned at same perpendicular with stirring arm 3, is directly fixed on ground, and in the discharging process, stirring arm 3 contacts with fixed mandril 6 tops; Elongation by hydraulic cylinder 7 drives left swollen mould 2 to rotate around major axis 5 with contraction.
