（2）Metal flitch advances certain under the action of feeding mechanism
（3）Lower template rises under the action of cam so that and metal blank is pressed on the lower surface of upper stamping knife by lower piston II, by
The air pressure of II lower part of lower piston provides pressure-plate-force during blanking shearing；
（4）Lower template continues to rise, and the compression metal blank of lower piston II is motionless, the outer cutting edge of lower stamping knife and the inner cutter hole of upper stamping knife
It is mutually twisted, sheet stock is cut from metal blank；
（5）Lower stamping knife continues to rise with lower template, and holding pad provides required when stretching for the first time under the promotion of actuator
Pressure-plate-force；
（6）Lower stamping knife continues to rise with lower template, the endoporus of lower stamping knife and the outer circle phase for the outer ram being fixed in middle template
Under interaction, sheet stock is done and is stretched for the first time；
（7）After completing to stretch for the first time, lower template, by the far point straight angle curve of cam, stops under the support of cam
At peak, while cope plate moves downward under the drive of connecting rod, and punch is as jumper bar is along jumper bar channel downlink；
（8）The metal flitch for completing first order stretching is pressed on the lower surface of outer ram, the lower surface of upper piston I by lower piston I
Metal flitch is also pressed on to the upper surface of interior stretch ring, lower piston I and upper piston I provide the pressure-plate-force when second level stretches；
（9）Punch is continued traveling downwardly with cope plate, under the collective effect of the endoporus of the periphery of punch and interior stretch ring, to cup body
Do second level stretching；
（10）Punch goes downwards to minimum point, completes second level pulling action, and cup body is molded completely；
（11）Pressure-air is poured to cup body inside by jumper bar, cup body is made to come off from punch；
（12）Cup body after coming off leaves cup press by glass channel that goes out in lower template；
（13）Lower template under the action of cam downlink until minimum point, cope plate under the action of carriage uplink until highest
Point completes a working cycles.
