Description of the drawings: 1. the bending forming die comprises a bending bottom plate, 2 a bending lower die, 3 a bending lower die single-port cavity, 4 a bending lower die double-port cavity, 5 a bending upper die single-port cavity, 6 a bending upper die, 7 a die handle, 8 a bending lower die double-port cavity, 9 a T-shaped tee joint, 10 a bending upper die double-port cavity, 11 a T-shaped tee joint double port, 12 a T-shaped tee joint single port, 13 a T-shaped tee joint double port I, 14 a three-leg tee joint, 15 a sinking forming cavity.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

In the prior art, a T-shaped tee 9 is shown in figure 1, a T-shaped tee double-port 11, a T-shaped tee single-port 12 and a T-shaped tee double-port 13I are filled with lead, extruded, tempered and softened, and then secondary filling of media is carried out, and a three-leg tee 14 is formed by bending through forming equipment and is shown in figure 2.

The specific implementation of the utility model is as shown in fig. 3 and 4, the bending lower die is fixed on the bending bottom plate 1 by screws, the bending upper die 6 is fixed with the die handle 7 by screws, a cavity for placing the T-shaped tee is processed on the die body of the bending lower die, a cavity corresponding to the lower die is processed on the die body of the bending upper die, the cavity of the bending lower die is composed of a bending lower die single-port cavity 3, a bending lower die double-port cavity 4 and a bending lower die double-port cavity 8, and the upper die cavity is composed of a bending upper die single-port cavity 5 and a bending upper die double-port cavity 10;

and a sinking forming cavity 15 is reserved on the lower die plate at the centers of the single-opening cavity of the bending lower die and the double-opening cavity of the bending lower die which are processed on the die body of the bending lower die.

The bottom plate is fixed on a workbench of the punch press through a pressing plate, and the die handle 7 is fixed and installed below a sliding block of the punch press and locked by a wrench. The punch table and the punch slide are prior art and the structure is not described in detail here.

During working, the big gear of the punch press is manually moved until the bending upper die 6 is in contact with the bending lower die 2, the positions of the bending bottom plate 1 and the bending lower die 2 are adjusted until the bending lower die single-port cavity 3 and the bending upper die single-port cavity 5 are matched, and the bending lower die double-port cavity 8 and the bending upper die double-port cavity 10 are matched, so that the bending bottom plate 1 is locked. Starting a punch start-stop button, placing the double-port 11 and 13I of the T-shaped tee joint into the double-port cavities 4 and 8 of the bending lower die, simultaneously placing the single-port 12 of the T-shaped tee joint into the single-port cavity of the bending lower die, starting a foot switch, driving the bending die handle 7 and the bending upper die 6 to move downwards by a punch slide block until the single-port cavity of the bending upper die is contacted with the single-port of the T-shaped tee joint, driving the bending die handle 7 and the bending upper die 6 to continue to move downwards by the punch slide block after the double-port cavity of the bending upper die is contacted with the double-port of the T-shaped tee joint, enabling the T-shaped tee joint to deform in a closed cavity formed by the single-port cavity 3 of the bending lower die and the single-port cavity 5 of the bending upper die, the double-port cavity 8 of the bending lower die and the double-port cavity 10. The punch press sliding block drives the bending die handle 7 and the bending upper die 6 to drive the formed triangular tee joint to continuously move downwards to fall into the sinking forming cavity 15 and fall out of the bending lower die 2, and the punch press sliding block starts to move upwards until the punch press sliding block returns to the initial position and stops.
