Automatic nut presenters

Product catalog summary
Overview
The document focuses on the automation of nut tightening processes using automatic nut presenters, which are designed to enhance productivity by reducing cycle times and operator fatigue in both manual and automatic assembly applications.
Specifications and Features
  • Automatic nut presenters provide a continuous supply of nuts, reducing cycle times by over 24% by eliminating manual pick-and-place phases.
  • Equipped with a high-capacity vibrating loader and adjustable feed speed controlled electronically.
  • Utilizes a pneumatic cylinder for nut insertion into a special socket on the screwdriver.
  • Compatible with straight air or electric screwdrivers with lever start.
Advantages
  • Increased productivity and reduced operator fatigue.
  • Higher quality of assembled products with no leftover nuts.
  • Long life and consistent performance, reducing maintenance and repair costs.
Assembly Process Examples
Examples are provided to illustrate time savings and efficiency improvements with and without nut presenters.
Technical Specifications
  • Dimensions and codes for various models, along with specifications for special sockets and retaining springs.
  • Recommended working pressure is 6.3 bar, with a 1/4” gas air inlet and a mains supply of 220 V, 50 Hz.
Additional Equipment
  • Reaction arms and linear slide rails improve ergonomics and precision.
  • Fastening slides can be integrated for fully automatic nut-tightening stations.
Conclusion
The document emphasizes selecting the right nut presenter and tools for specific production needs, with Fiam Technical Consultancy Service available for assistance.

When bench or line assembly requires the use of very small nuts, time is essential to increase production. The innovative systems for fastening with automatic nuts feed notably reduce the cycle-time and thus improve productivity. This is why: ^ They offer an easy and continuous supply of nuts to be tightened ^ For MANUAL use, they eliminate the phases of picking and placing the nut, making the operator's work easier, as they allow the nut to be picked up directly with the screwdriver without using the hands, while for AUTOMATIC use, they speed up tightening operations with effective and always...

N ED Tightening systems for Pick and Place for manual or automatic use The N ED “Nut EasyDriver” nut presenters can be used for both manual and automatic tightening systems and are designed to ensure extremely fast and smooth nut drafting for optimum operator convenience and comfort, resulting in improvements in cycle times and therefore productivity. The nut feed speed can also be adjusted thanks to the integrated electronic unit, a condition that is especially useful when using the presenter in automatic tightening stations. In fact, the innovative mechanical features make N ED presenters an...

NUT PICK UP AND RETAINING SOCKET The nut picking and retaining sockets, are designed with small radial encumbrance, which makes the system usable even in the tightest tightening points with restricted space and access. They pick up and retain the nut mechanically, thanks to a tweezer that holds the nut firmly internally, on the thread, during pick-up and translation steps, without risk of losing it on components. SOCKET GUIDE The socket guide (B) is always to be interposed between the nut picking and retaining socket (C) and the screwdriver or nutrunner motor (A). • in the manual version it prevents...

REACTION ARMS Fiam telescopic and cartesian arms completely counteract the reaction on the operator's hand, the force required to support the tool and the vibrations to the hand-arm system. They make it possible to keep the wrist in a good position with the tool perpendicular to the work point, improving working accuracy and production process quality. They are entirely designed and produced by Fiam as are all the accessories and numerous devices to improve the ergonomics of the workplace and safeguard the health of the operators. Available in several versions: • Telescopic arms • Cartesian arms...
