fasteners & spring production

A new line and a new range from Fenn Fenn Technologies has unveiled a new wire flattening and shaping line. Designed for high precision rolling and shaping of ferrous and non-ferrous wire, the line pictured is ideal for rolling high tensile stainless and alloy steels up to approximately 250m/min (800ft/min). The machine contains the a spool pay- off, two two-stand rolling mills, a coolant system, Turkshead, cleaning tank, four dancers, a skiving head, exhaust ducts for dust/mist collection, a Vollmer thickness gauge, Laser mic for width measurement, double capstan, traversing take-up winder and complete safety guarding. This highly adaptable line is easy to use with some or all of the noted components. Initially built for the US market, the line is also fully CE compliant. At the recent Casmi Spring Show, Fenn also demonstrated a Z11- 2 axes CNC constant force machine complete with tooling and die set, making a constant force spring from 12.7mm x0.38mm-301 high yield stainless steel strip. The spring had 508mm of feed length in the body, with a 20mm inner diameter and curled tail with formed end and punched hole.

Tooling and die set on the Z11 2-AXIS CNC constant force machine are determined by strip size and end configuration. Currently, Fenn offers three different Z series models, which are capable of covering a strip width range up to 50mm and thickness range up to 1mm. Feed roll adjustment is from the bottom, with built- in load cells for setting roll pressure.
