Specific implementation mode
As shown in Figure 1 and Figure 2, the present embodiment includes：Upper die mechanism 1, lower die mechanism 2 and mandril protection mechanism 3, wherein：On
Mold mechanism 1 is movably set in the top of lower die mechanism 2, and mandril protection mechanism 3 is set to the inside of upper die mechanism 1.
The upper die mechanism 1 includes：Upper mold outer cushion block 101, inner punch 103, punch centre circle 104,105 and of punch outer ring
Cushion block 106 in upper mold, wherein：The upper end of the outer cushion block of upper mold 101 is equipped with the groove 102 for air inlet, the upper end of inner punch 103 with
The lower end of cushion block 101 is fixedly linked outside upper mold, and cushion block 106 is set in turn in punch centre circle 104, punch outer ring 105 and upper mold
