Features of RBF Series 6 Station Bolt Former

01

Coordinated Clipping Table Movement

To achieve synchronized movements, a j-pint intermediate shaft drives both the reciprocating movement of the clipping table and the opening/closing of the clips.
02

Adjustable Rear Knock-Out Mechanism

Rear knock-out mechanisms can be individually and separately adjusted for different stations. The last station is. All models' dead-point positions remain the same prior to being removed. Rear knock-out threaded pipe adjustment mechanisms can be added to some models using a hand wheel or a CNC machine.
03

Overload Protection

RBF serial model's punch knock-out mechanism. Punch knockout occurs at the same time as the machine slider's back movement. The work piece remains in the mold after being moulded before being knocked out by a rear knock-out mechanism. It avoids getting distracted by the punch and being malformed. The placements of different front knock-out stations can be individually changed. All of the front lead-out mechanisms feature provisions to protect against knock-out forces exceeding loads.
04

Quiet and Efficient Electric Feeding Mechanism

Is the feeding mechanism electric, During the return stroke, the air cylinder has the ability to lift the pawl and detach it from the ratchet wheel. In addition to removing friction and noise, this bolt forging machine also stops the ratchet wheel from turning in the other direction.
