Specific embodiment
As shown in Figure 1, a kind of stamping die of integral type ball-type multi-way pipe fitting, it is characterized in that it includes mold base 11 and punching
First 12, a punching hole 11.1 is equipped in mold base 11,11.1 top of punching hole is cylinder, and 11.1 bottom of punching hole is hemisphere
Shape, even circumferential is distributed 3 hydraulic through-holes 11.2, the punch section shape and mold base of formed punch 12 in hemispheric mold base 11
11.1 shape of punching hole in 11 is corresponding, in formed punch 12 be equipped with a hydraulic expanding-forming recirculation hole 12.1, with 12 bottom of formed punch
Equipped with hydroforming hole 12.2 corresponding with hydraulic through-hole 11.2, hydroforming hole 12.2 and 12.1 phase of hydraulic expanding-forming recirculation hole
