Abstract

The invention discloses a hydraulic punching and flanging device used between concentric pipe piece cylinders. The hydraulic punching and flanging device is characterized in that the inner and outer concentric pipe piece cylinders can be simultaneously positioned and installed on a core seat through a positioning core seat and a positioning plug. An oil through hole and a piston cavity are formed in the positioning core seat, and the oil through hole is communicated to the piston cavity. A punching and flanging piston is installed in the piston cavity, and the head portion of the piston is step-shaped for punching and flanging achievement. When the cylinders are machined, high-voltage hydraulic oil acts on the piston, and the piston produces high pressure to jack the inner cylindrical wall of a concentric pipe piece. A turnup is connected with the outer cylindrical wall after the inner cylindrical wall is stressed to deform. Accordingly, the inner cylindrical turnup of the concentric pipe piece is located on a reserved hole formed in the outer cylindrical wall to enable the inner cylinder and the outer cylinder to be connected together. By means of the hydraulic punching and flanging device, the production efficiency of punching and flanging connection can be greatly improved, meanwhile the connection cost of the concentric pipe piece cylinders is saved, and the difficulty of punching and flanging connection of the concentric pipe piece cylinders is overcome.
