Start press, in the punching hole by punch holder circular blank extrusion die seat, forms a semi-finished product；Then it extracts
Formed punch is inserted in button die on formed punch；Continue to squeeze semi-finished product by formed punch, while leading in the hydraulic expanding-forming recirculation hole of formed punch
Enter highly pressurised liquid, extruding and hydraulic expanding-forming by hydroforming hole to semi-finished product form branch pipe bulge, it is more that ball-type are thus made
Way pipe fitting semi-finished product；The diameter D and master of bushing outer diameter and thickness and finished product integral type ball-type multi-way pipe fitting circular straighttube cylinder
Thickness of pipe wall T-phase is same, and bushing height is 1.5~2.5 times of branch pipe height H；
(3), ball-type multi-way pipe fitting semi-finished product obtained in step (2) are taken out, branch pipe bulge cut being formed
Branch pipe, thus finished product integral type ball-type multi-way pipe fitting.
The utility model compared with prior art possessed by advantage are as follows: the integral type ball-type multi-pass pipe of the utility model
Part has abandoned branch pipe welding mode using the integrated structure of rounding off, avoids weld stress concentration, reduces leakage
Link improves the reliability of multi-way pipe fitting；Branch pipe is arranged on hemispherical cylinder in the utility model, can be by main line
Homogeneous media distribute and be transported to a plurality of bypass line, the homogeneous media of a plurality of pipeline can also be concentrated and be transported to one
Main pipeline.

Specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, a kind of integral type ball-type multi-way pipe fitting, it is characterized in that it includes being responsible for 1 and branch pipe 2,
The upper semisection of supervisor 1 is circular straighttube cylinder 1.1, and the lower semisection for being responsible for 1 is hemispherical cylinder 1.2, and circular straighttube cylinder 1.1 is straight
Diameter is equal to the diameter of hemispherical cylinder 1.2；On the integrally formed hemispherical cylinder 1.2 for being provided with supervisor 1 of 3 branch pipes, branch pipe 2 exists
It is circularly and evenly distributed on hemispherical cylinder 1.2, the angle α between branch pipe 2 is 90 °.
As shown in figure 4, stamping die comprising mold base 11 and formed punch 12 are equipped with a punching hole in mold base 11
11.1,11.1 top of punching hole is cylinder, and 11.1 bottom of punching hole is hemispherical, and circumference is equal in hemispheric mold base 11
3 hydraulic through-holes 11.2 of even distribution, the punch section shape of formed punch 12 is corresponding with 11.1 shape of punching hole in mold base 11, In
A hydraulic expanding-forming recirculation hole 12.1 is equipped in formed punch 12, it is corresponding hydraulic with hydraulic through-hole 11.2 being equipped with 12 bottom of formed punch
Shaped hole 12.2, hydroforming hole 12.2 are connected with hydraulic expanding-forming recirculation hole 12.1.
As shown in figure 5, when preparing integral type ball-type multi-way pipe fitting, first cut a circular blank, blank with a thickness of at
1.2 times of the supervisor wall thickness T of product integral type ball-type multi-way pipe fitting；The diameter of circular blank is equal to 2L+3.14*SR+2H+10,
Wherein L is the length of straight pipe of finished product integral type ball-type multi-way pipe fitting circular straighttube cylinder, and SR is the radius of a ball of hemispherical cylinder, H
For branch pipe height；The circular blank of well cutting is placed in above stamping die, blank center is aligned with mold center；Starting pressure
Machine squeezes into circular blank in the punching hole 11.1 of mold base 11 by formed punch 12, forms a semi-finished product；Then formed punch is extracted
12, button die 21 is inserted on formed punch 12；Continue to squeeze semi-finished product by formed punch 12, while circulating in the hydraulic expanding-forming of formed punch 12
It is passed through highly pressurised liquid in hole 12.1, extruding and hydraulic expanding-forming by hydroforming hole 12.2 to semi-finished product form branch pipe bulge
22, ball-type multi-way pipe fitting semi-finished product are thus made；Bushing 21 outer diameter and thickness and finished product integral type ball-type multi-way pipe fitting is round
