By pass through slot.
The principle of this programme is as follows：
When upper die holder moves down, spacing collar and punch are downwards close to lower die mechanism.When initial, between adjacent arc block
Distance it is larger, after contact at the top of spacing collar bottom and arc block, spacing collar can not continue to move down, thus work as upper die holder after
Continuous when moving down, inflation cylinder is moved down with upper die holder, and spacing collar is moved up relative to inflation cylinder, and spacing collar pushes away
The piston of dynamic inflation cylinder is slided into inflation cylinder.The space for inflating the piston on the side that cylinder is located at inflation cylinder reduces, presses
Power increases, and the gas inflated in cylinder enters in fixed cylinder, and the pressure in fixed cylinder is made to increase, the piston of fixed cylinder to
It is slided outside fixed cylinder, pushes several arc blocks to far from one Slideslip of fixed cylinder, the distance between adjacent arc block reduces,
Last several arc blocks can form columned lower die, and extrusion chamber is formed between several arc blocks.
