Manufacturing Technology

Videx Machine Engineering, a manufacturer of machinery for the wire and fastener industry, is automating its cold heading and hot forging lines for greater production efficiency.

Videx states that its hot forging machine is now a complete line, starting from bars or coils. The line will feed the bars; shear them to length; chamfer and extrude their ends; forge a head in a closed die without trimming; followed by cooling and threading. The company’s forging machines are available in 100 metric tonne to 500 metric tonne configurations and can produce a thread range from M20 to M48 upwards, with part lengths from 250mm – 1,000mm. The production rate of the machines is 4 - 6 parts per minute and the automated lines will now automatically and efficiently manufacture long, headed fasteners without trimming.

Videx’s open die cold headers are now also offered as automatic lines, starting from coils or bars. The lines start with a wire straighten, cut and chamfer machine, after which the cut to length parts are fed into a
multi-operation transfer machine, which will turn, chamfer and face the ends, stamp them, drill them and even insert aluminium balls for weld studs. Once all these operations are complete, the parts are transferred to a dual station cold header, where they are headed on the opposite side.

These newly automated lines are an efficient solution for the production of such products as cold headed long bolts and weld studs.
