S3: the thickness face pressure tack goes out stock column far from the steel bar, and the steel bar in the discharge hole continues to stretch out, the width
The closely described steel bar of face bending head rest goes out stock column, and the thickness face of the steel bar is fastened on the thickness of the pedestal of the width face bending head
In the card slot of face, outer rotating seat rotation drives and keeps off curved column movement, the width face of steel bar described in third time bending, in the discharge hole
Steel bar continue to stretch out, outer rotating seat reversely rotates, drive and keep off curved column movement, the width face of steel bar described in the 4th bending；
S4: the width face bending head goes out stock column far from the steel bar, and the steel bar in the discharge hole continues to stretch out, the thickness
Bending column in face goes out stock column close to the steel bar, and the width face of the steel bar is arranged in the width face card slot of " youngster " shape, outer rotation
Seat rotation drives and keeps off curved column movement, the thickness face of steel bar described in bending；
S5: the thickness face bending head goes out stock column far from the steel bar, and a staking punch goes out stock column close to the steel bar, and liquidates
Hole pressing plate carries out punching press, so that the punching die of punching pressing plate is to the steel bar punching；
S6: the staking punch goes out stock column far from the steel bar, and discharge hole continues to stretch out steel bar, rushes after salient point to head and is rushing salient point just
Corresponding pressing is carried out to the closely described steel bar of head rest and centered on the steel bar to rush a little, will get salient point on the steel bar；
S7: described to rush after salient point to head and the salient point forward direction head that rushes far from the steel bar, another staking punch percussion cutting-off is beaten
Hole pressing plate, so that the cutter and perforating mold of cutting punching pressing plate cut off to the steel bar while connect for next wiper
The production of bar is punched.
