The New NX615 Fly-Over-Punch Transfer Module

In cold forming, every split second matters. During this process, parts must be transferred precisely from one station to the next for consistent quality and productivity. When transferring parts between stations, even a slight delay can cause a part to drop, rotate, or misalign, leading to interruptions in production.

For short or shoulder-type parts, this challenge becomes even more critical. That is why Nedschroef Machinery developed a new solution for the NX615 header: the Fly-Over-Punch (FOP) Transfer Module, designed to make every cycle faster, more precise, and more reliable.

In high-speed production, even a few degrees of movement can be the difference between a successful transfer and a dropped part. In high-speed production, even a few degrees of movement can be the difference between a successful transfer and a dropped part.

Improvement Opportunity on the Traditional Mechanical Transfer

The traditional mechanical transfer is a robust and reliable production asset. However, there’s one area where improvement is possible.

In this system, the transfer fingers must wait until the main slide (punch) moves back far enough to create clearance before the fingers can move sideways. That short delay limits the speed at which the next part can be safely grabbed and transferred.

The new FOP Transfer eliminates this waiting time.

By lifting the fingers over the punch upon opening, the sideways movement can begin significantly earlier. This means the transfer can grab the product faster than the traditional system, further reducing the unsupported time. As a result, parts are less likely to drop or rotate.

• In the traditional transfer, the fingers (red) wait for the punch to retract before they can start moving sideways.
• In the FOP design, the fingers (grey) are already moving to the next station — allowing earlier movement and ensuring faster, more reliable part handling.

• Traditional Mechanical Transfer: starts sideways movement 20° after the main slide’s Front-Dead Center (FDC).
• New FOP Transfer: starts 25° earlier, at 5° before FDC.
• Result: the transfer fingers close and grab the part sooner: 250° on the FOP vs. 270° on the traditional system.
• Gain: 47 mm of main slide movement, ensuring that even the shortest and most unstable products are secured quickly and reliably.

We didn’t stop at functionality. Drawing on extensive field experience with previous transfer implementations, the NX615 FOP Transfer was designed to maximize maintenance intervals and deliver industry-leading reliability.

Enhanced Flexibility and Support

• Timing Flexibility:
  Combine the FOP Transfer with our adjustment system to finely tune the sideways movement to your specific product requirements.
• Ultimate Short Product Reliability:
  Pair the FOP Transfer with the short product support feature to keep even the smallest parts supported immediately upon die ejection, guaranteeing the FOP can grab them with full confidence.

A Foundation for the Future

This new mechanical FOP design is modular and ready for further evolution, including integration with finger force monitoring and forming the groundwork for its deployment across the entire NedForm product family.

Conclusion: Fast, Flexible, Robust

The new NX615 FOP Transfer delivers tangible production benefits:

• Faster part grabbing
• Higher reliability
• Full readiness for your most challenging cold forming applications

Overall, the NX615 FOP Transfer provides a clear step forward in production control and precision. It offers all the benefits of a mechanical system but with faster handling, better stability, and lower downtime for modern cold forming operations.
