The working principle or the using method is as follows:

when the equipment starts to work, the parts are already fallen on the mold core of the turnover block 32, at the moment, the stamping plate 11 slides downwards to drive the piston rod 42 to slide downwards, at the moment, the switch device on the air inlet 412 is in a closed state, thereby generating a negative pressure in the piston tube 41, thereby generating a suction force through the suction cup port 322, therefore, the part is adsorbed on the mold core through the sucker port 322, so that the part is completely attached to the mold core, thereby completing the positioning and locking of the mold core, at the moment, the stamping plate 11 continues to move downwards, it pushes against the top touch rod 511, and drives it to slide downward, so as to drive the slide block 51 to slide downward, so that one end of the first link 53 moves downward, so that the other end thereof pushes the sliding shaft 321 to slide along the sliding groove 521, thereby rotating the turnover block 32, when the sliding shaft 321 abuts against the right end 3122, the turning block 32 is in a vertical state, and the punching hole 325 thereof is aligned with the punch 111.

The punching plate 11 continues to slide downwards, and one end of the first link 53 can not move any more, so the telescopic rod 531 thereon begins to retract into the telescopic sleeve 532, and the third elastic member 533 is compressed, so that the distance between the two ends of the first link 53 becomes small, and the punching plate 11 can continue to descend, and the punch 11 thereon passes through the punching hole 325 to perform punching operation on the side surface of the part locked in the turning block 32.

After the stamping plate 11 finishes stamping, the piston rod 42 just abuts against the press-contact switch, which controls the switch device on the air inlet 412 to open, so that the outside air enters into the piston tube 41, the negative pressure in the piston tube 41 disappears, and the adsorption force on the component disappears, at this time, the stamping plate 11 starts to move upwards, and drives the piston rod 42 to move upwards together, so that the switch device on the air inlet 412 is closed, and the piston rod 42 moves upwards, and the air in the piston tube 41 is discharged through the sucker port 322, and the stamping plate 11 slides upwards, so that the pressure on the abutting rod 511 disappears, and the abutting rod 511 abuts against the stamping plate 11 under the action of the first elastic member 54, and slides upwards along with the same, so that one end of the first link 53 moves upwards, so that the telescopic rod 531 on the first link 53 slowly extends out of the telescopic sleeve 532, and the position of the telescopic sleeve 532 remains unchanged under the action of the third elastic member 533, when the telescopic rod 531 and the telescopic sleeve 532 return to the initial state, the two are limited to each other, so that the distance between the two ends of the first connecting rod 53 cannot be increased, and one end of the first connecting rod 53 continues to move upwards, so that the other end moves along with the first connecting rod, and the turnover block 32 starts to turn back.

In the process that the distance between the two ends of the first connecting rod 53 is increased, the overturning block 32 is always kept in a vertical state, air extruded by the piston rod 42 acts on the part to enable the part to be separated from the mold core, and meanwhile, the part moves outwards under the most use of blown air and finally falls downwards under the action of self gravity.

When the stamping plate 11 moves upwards to be separated from the contact with the abutting rod 511, the rope 25 is just in a tensioned state, the stamping plate 11 continues to move upwards, one end of the rope 25 is driven to move upwards together, the other end of the rope pulls the sliding piece 232 to slide forwards, the rotating finger 231 is driven to move forwards together, when the part passes through the platform plate 311, the rotating finger 231 abuts against the part, the rotating finger 231 cannot rotate backwards due to the limiting piece 2321, so the part is driven to move forwards together, the part falls onto the mold core of the turnover block 32, after the part leaves the platform plate 311, the feeding belt 21 can automatically detect that the part on the platform plate 311 disappears, the part starts to rotate, the part on the part is supplemented onto the platform plate 311, when the stamping plate 11 punches downwards, one end of the rope 25 also moves downwards together, so the sliding piece 232 slides backwards under the action of the second elastic piece 24, when the rotating finger 231 moves backward along with the slider 232 and the rotating finger 231 abuts against the part on the platform plate 311, the rotating finger 231 rotates forward, thereby following the slider 232 to pass through the part on the platform plate 311, and after passing, under the action of its own gravity, the rotating finger 231 rotates downward to abut against the stopper 2321 again.

This concludes a cycle.
