Specification are subject to change as we keep making improvements in design.

REMARKS:

  • The material of cut-off and forming shown above are for low/medium carbon steel and high-tensile alloy steel.

  • Max/Min. size & length under head indicate standard hexagonal bolt.

  • All machines are equipped with air clutch brake of 5.5-6.0 kg/Cm2 air pressure.

  • All machines are equipped with automatic circulate lubricating system.

  • The max. speed of output should be discussed in advance with stain steel and special trail.

  • Modification subjected to change without any notice.

  • DESCRIPTION OF BOLT FORMER

  • 1. The air clutch brake system has been designed to allow the motor to start from no load condition, and also able to actuate as "Inching", "Single Stroke"  and "Continuous Running". The main side will always stop at rear position when operating either "Single Stroke", or "Continuous Running" cycle.

  • 2. The solid cut off die and knife ensures a square cut and clean edges.

  • 3. The cut off cam follower is designed at the center of the cut-off carrier rod to avoid eccentric force occurred on the cam follower pin and to maintain the rigidity and longevity of the machine.

  • 4. The positive knock-out cam in the punch side was designed by computer to achieve simplicity and precision Punch side knock out timing coincides with the main slide movement to prevent spill out of materials from forming die before knock out.

  • 5. The last station rear knock out mechanism can do normal slow motion knock out by simply changing the knock out cam which is designed for easy replacement.

  • 6. The main machine parts like frame or main slide has been normalized to release the internal stress after casting. It means to avoid deformation in the future and keep precision forever.

  • 7. All cam diagram in this machine is designed by Computer program and machined through Machining Center (MC) to gain smooth surface and accuracy.

  • 8. The stability and precision of the main slide is secured by "Overran" designed and the application of harden alloy steel plates fixed to it will help maintain its precision for a long period of operation.

  • 9. This machine is equipped with automatic checking device, called Auto-Checker, which will sensitively stop the machine and to indicate to your operator in case of:  

    • » Mal-function of front punch knock out

    • » Mal-function of rear ejection

    • » Overload

    • » Materials short feed

    • » Production reach to counter pre set figure

A limit switch mounted in front of the straightened wheels will automatically stop the machine when the material runs out.

The cut-off mechanism and its drive have been simplified. The cut-off roller is supported on both ends for rigidity. The picture also shows the balancing weight on transmission gears.





OTHER FEATURES

The semi finished products are pushed out of the dies by three knock-out levers which are independently adjustable. They are controlled by a camshaft underneath. The third cam can be easily changes for trimmed or untrimmed bolts.

The main slide extends to the rear of the crankshaft for better balance. The yellow colored lever is the synchronized positive knock-out lever for the front punches. Since the motion is synchronized with the connecting rod, it is independent from the position of the main slide.

The picture shows that maximum working areas is provided. The longitudinal position and the alignment adjustment for the forming die and the three front punch are independently adjustable. The mounting and dismounting of the punch is affected by one screw.

Gripper transfer shaft is running freely and smoothly on Liner Bush. The Gripper mechanism can be swung up for die change and the cassette type gripper slide base can be taken off the machine for quick set up
