Fastener & spring production

“ ACID-FREE PROCESS FOR STEEL ROD CLEANING & SURFACE PREPARATION” “New Way to Draw Steel Wire in the 21 st Century”

Rolling technology for production of spring wire DEM’s ProfileWire Rolling line (PWR) for the production of spring wire consists of a payoff for wire unloading, a pre-straightener, three motorised high-precision rolling stands, a laser for dimensional deviation control and a take-up system such as coiler, spooler, calander or facilities for cutting, straightening and unloading of straight bars. The lines can cover any range of product size up to 500mm 2 , with speeds of up to 1,200m/min, and can be customised to specific requirements. The core of the system is the latest generation DEM rolling stand, which allows demanding tolerances to be achieved thanks to a new tool arrangement design, accurate profile measurement and self-adjustment on closed loop control.

DCCD process features: • Eliminates acid, borax and precoatings • Zero energy consumption • Direct drawing from bare rod with no speed limitation, for H/C and L/C • New Lubricant Viscosity Control provides exceptionally adherent coating • Adjustable lubricant residual • Zero lubricant waste • Recommended for severe drawing applications (spring, rope, bead, CO 2 welding, PC strand, plating quality) • H/C wire drawn at 18 m/s (3600 ft/min) • Up to 8 times longer die life • Exiting wire temp. 45°C (113°F) • Greatly improved wire ductility

Profile wire rolling line from DEM

▲

Line operation is controlled by user-friendly supervisor software. All production and set- up parameters can be stored in the automation system and retrieved as required for repeating production campaigns. DEM provides advanced rolling solutions for the cold rolling industry, for ferrous and non-ferrous metals. In addition to complete profile wire rolling lines, DEM can supply complete rolling lines for flat wire; complete rolling lines for the production of concrete reinforcing wire in coils at high speed; complete rolling lines for the production of concrete reinforcing wire in bundles at high speed; rolling cassettes for wire rolling and rope compacting; micro-cassettes to replace traditional dies in drawing lines; and tube forming technology for flux cored wire (welding wire).

Bacchetti and manufactures motor driven decoilers, for both coils and reels, for the wire and cable industry for the feeding of spring making machines, straightening machines and cable cutting machines. TheHDTV1000decoiler has beendesigned for wire in coils or bundles, with minimum loading diameter of 300mm, and for springs wire diameter from 0.6 to 5.5 mm. The decoiler allows easy positioning of the coil on the horizontal loading plate, which has a 1,200mm external diameter. The material to decoil goes from the coil to a first diversion device, then to a moving arm, and finally to an external tacho- dynamo device. The rotation of the motor of the decoiler can be controlled by both Motor driven decoiler sas, Italy, designs

the moving arm and the tacho-dynamo device. All operating parameters of the decoiler can be set on the control panel. Maximum speed is 55rpm and the maximum capacity is 1,000kg. The height of the loading plate from ground is 870mm, and the overall dimensions are 2,000 x 1,250mm. Thecompanyproduces a rangeof decoilers with vertical axis of rotation, for wires from 0.2 to 16mm diameter, feed capacity from 30 to 2,500kg, plate diameters from 600 to 2,500mm, and maximum rotating speed from 18 to 90rpm, on request.
