Straightening, cutting & welding Advantages of ultrasonic welding Ultrasonic welding is said to offer important advantages to manufacturers. It creates solid-state metallurgical bonds without the need for filler metal materials or for clipping, soldering, crimping, or dipping. The welding process is also accomplished without producing arcs, sparks, or fumes and without melting wires. The Dual Head SpliceRite™ ultrasonic wire splicer – like other Sonobond Ultrasonics metal spot welders – utilises the patented Wedge-Reed system. This system combines

Flying shear straighten and cut machinery In 2002 Videx launched its first paten- ted servo-operated straighten and cut machine, which enabled cutting of both short and long parts at high speeds without clutches or hydraulics. Following the success and the improved reliability of this line, Videx is now launching its flying shear straightening and cut-off machine with the same patented servo-drive. Servo machines are quieter and more reliable, need less floor space and allow higher cut-off rates. The wire speed and cut-off rate are programmed on an HMI screen that stores the data and displays all possible interface and fault messages. fully mechanical, combining the advantages of the reliable mechanical cut with the benefits of the servo-drive that replaces the traditional clutch used by other machines. The VC-MSR machines are

high vibratory force with low amplitude coupling. During the welding pro- cess, the unit directs high frequency ultrasonic energy via the welding tip to the surface between the metals to be bonded. The vibratory energy disperses the oxides and surface films, creating a true metallurgical weld. There is no melting of materials. In addition to creating a very reliable bond, the process is environmentally friendly, produces no waste, and consumes minimal energy.

Sonobond’s Dual Head SpliceRite™ ultrasonic wire splicer accommodates ▲ ▲ bundles with cross-sectional areas up to 100mm 2

True to its name, the Dual Head SpliceRite has two welding heads, one on each side of the weld area. As a result, larger wire bundles – those up to 100mm 2 – can be spliced in just one quick step. This is true even when wires are tinned or heavily oxidised. The resulting welds have excellent conductivity. In addition, the unit has a 3,500-watt power supply and a microprocessor controller that can store and recall up to 250 jobs. Welds can be controlled by height, by energy or by time. All Sonobond metal spot welders feature heat-treated, tool steel taper lock tips. These tips can last for 100,000 welds or more. They are designed for quick tooling changes and foolproof placement. Sonobond units also have an important advantage in that they require only minimal training, being easy to operate.

The product, named Condorlube S 300, is water-based and free of hydrocarbon solvents or mineral oil. The straightened surface appears clean, dry and protected for in-house storage. Condorlube S 300 straightening solution can be continuously purified and regenerated using the Athena unit supplied by Condoroil Chemical’s sister company, Condoroil Impianti.

Chamfered rods using Videx technology ▲ ▲

The run-off guide is made from stainless steel, requiring no adjustment when changing wire diameters within the machine range. The gate of the run-off guide is pneumatically operated, and supports the wire during cut-off to assure a square cut face. The wire transmits the cut-off signal, just before it hits the positive stop. The positive stop itself is mounted on a carriage that rides along the run-off guide. When the flag “feels” the wire, it actuates the cut-off cam to cut the wire and return to rest until the next time the wire hits the positive stop. The VC machines are offered with an integral chamfer station that can chamfer, face and turn the bars after chamfering.
