Dual-spindle thread rollers
Videx dual-spindle thread rollers will roll threads above and below
the shoulder; the threads can be either different or similar. The two
heads are independent, eliminating any influence of one on the
other and enabling the use of simple and economical rolling dies.
The advantages are said to include:
Independent adjustment assures better quality of each thread •
Higher production speeds, as the second operation does not •
slow the machine
Reduced handling, eliminating the possibility of mixing parts
•
Inexpensive tooling and full control of the quality of each rolling •
operation. Tools can be replaced in minutes
Both stations have controlled thread
rolling start, hydraulic clamping, zero-taper
mechanism for parallel threads and
micrometric thread pressure screws. Other
features include speed controller, automatic
air shut-off and dual operator control panel.
Main features:
Closed frame - the main spindle is pivoted
•
on both sides for parallel threads on long
and high tensile fasteners, preventing
breathing and resulting in extended die
life
Hydraulic clamping of the thread rolling •
dies and micrometric screws for precise
adjustment of the thread rolling dies
Controlled feed, equalising the line speed of the blank to the •
rotary die speed, eliminating slippage and resulting in improved
quality threads
Stainless steel feed rails are manually adjusted, needing no •
wrenches. A spring-loaded upper rail over a wide hold back
finger, provides parallel feed and precise thread length
Automatic air shut-off to the feeder and the feed rails
•
Fine thread match on each station. Independent and precise •
die match at the touch of a finger
AC speed controller enables running at the highest possible •
rate
High speed vibratory feeder with fine adjustment settings. •
To change thread length, the whole feeder is lifted, from one
point, with the feed rails
Computer with digital screen for messages and data •
No maintenance as there are no clutches, slides or hydraulics •
