REMARKS

The company keeps the right to revise above parameters. If there is any alterations , advance notice won't be given then.

The products' most applicable production speed is decided by the product shape, size and material.

Maximum material shearing diameter and product size listed in the table can be calculated according to medium carbon alloy steel. It is equal to 10.9 grade high Intensity screw.

Features of QLBF Series 3 Station Bolt Former

01

Compatible Reversible Nuts and Fixed Bolt Clips

Reversible nuts and fixed bolt clips that match with RBF serial multi-station parts forming machine.
02

Swing Transfer Conveyance

Transfer conveyance of rotary swing mode and transfer force of adjustable pneumatic mode ensures stable and reliable work-piece conveyance and high speed operation of the machine. The first station clip can automatically loose short dimension feeding, stop and alarm.
03

Coordinated Reciprocating Movement

Reciprocating movement of clipping table and opening/closing actions of the clips are both driven by a jpint intermediate shaft to ensure the coordinated actions.
04

Optional CNC Type Adjusting Mechanism

Is rear knock-out mechanism. Rear knock-out mechanism of various stations can be respectively and independently adjusted. Last station can. Before being kicked out, dead - point position of all models keeps the same. Some models can choose to add hand - wheel type or CNC type rear knock-out threaded pipe adjusting mechanism.
05

Independent Adjustment and Overload Protection

Is punch knock - out mechanism of RBF serial model. Punch knock - out coincides with back action of machine slider. After the work piece is shaped, it stays in the mould and then being kicked out by rear knock - out mechanism. It avoids being talken away by the punch and then get deformed, Various stations of front knock - out positions can be independently adjusted. All the front lead - out mechanism have knock - out force over- load protection devices.
06

Automatic Pawl Lifting and Noise Reduction

Is electric feeding mechanism, In return stroke, pawl can be automatically raised by air cylinder and be separated from ratchet wheel. It not only removes friction and noise, but also prevents ratchet wheel from reversal operation.
