Videx Machine Engineering Ltd has recently completed the updated design of a wheel bolt machine that is capable of thread rolling 320 – 360 wheel bolts per minute.
The Videx dual-spindle machine accepts headed parts directly from the header or from a vibratory feeder. It thread rolls in the first station and knurls under the head in the second station. The thread and knurl rolling operations are independent of each other, eliminating any influence of one rolling operation on the other. Thus enabling faster production rate, better quality parts and the use of simple and economical rolling dies.
Individual adjustments on the machine require less operator skills and also enable better control of the quality of each rolling operation. Separate rolling operations also assure better quality of the knurl and thread. The machine also features higher production speeds with the second operation not slowing down. Other advantages include less handling, eliminating the possibility of mixing parts, as well as lower cost tooling – the dies are replaced in minutes and only when needed.
Both stations are equipped with controlled thread rolling feed-start, auto die clamping, zero-taper mechanism for parallel threads and micrometric thread pressure screws, as well as full speed control, automatic air shut-off and two operator control panels.
