News Technology Fasteners return for owner

David Wiesenfeld, founder and owner of Videx Machine Engineering, started his way in the fastener industry 50 years ago, as a plant engineer in an Israeli fastener plant. He gained his experience in hot forging at that time and had always dreamed of returning to this business. His dream was fulfilled last year and Videx has added hot forging lines to its portfolio. The Videx hot forging lines are the first fully automatic lines for long and large bolts. The forging machines are available in 300, 400 and 500 metric tons, covering the thread range of M-20 to M-48 (¾" to 2") in the smallest machine and up to M-80 (3") in the largest machine. The length range is 200-1,000mm (8"-36") under the head. The hex is formed in a closed die and it does not need trimming. The production rate is four to six parts per minute.

The complete line consists of the following machines: • Impact cutter, cutting long bars to length • Chamfer machine, accepting cut-to-length bars from the impact cutter or from a one-row magazine • Extrusion machine, extruding the chamfered side • Induction heating machine (not made by Videx) • Forging machine with solid die, double blow, with 300/400/500 metric tons capacity The forging machine has five stations – one feed station, two forging stations and two ejecting stations. The chamfered and extruded bars are fed into the die by a pneumatic piston. Then, the dial indexes the parts to the first forging station, which upsets the parts and breaks the scale. In the next station, the hex is formed in a slide-closed die. After heading, the parts are indexed to the ejection position, where they are ejected to a conveyor which takes them out of the machine area. The machine is supplied with a spray system for cooling and lubricating the die and punch. Additionally, Videx offers the machines as self-standing independent units.
