THE CLUTCH MECHANIZM OF AXIAL HEAD

THE CLUTCH MECHANIZM OF AXIAL HEAD

 

          Axial-head has the crutch in it, and automatically release the work-piece after the rolling process finished. Due to this function, the head can return speedy to home position without touching work-piece.

          * The left picture is indication the rotational direction of "F TYPE" head.

          Rotational Direction will be false with "G TYPW" head.

 

Ways to OPEN / CLOSR the head
How to… HEAD METHOD DETAIL
OPEN F TYPE  Use "Stop Screw" "Stop Screw" is a tool to regulate the length of thread  processing. The clutch will be released , and the head will be open when the work-piece touches ths "Stop Screw"
G TYPE
R TYPE
F TYPE  Stop the feeding movement of machine  With stopping the feed and keeping the spindle turning, the front side of head keep moving forward automatically by the friving jpower of rolling until the clutch to be released.
G TYPE
R TYPE  Stop the rotation with holding from outside  Need to attach the "York" on the head. When the "York" touches the "Stopping Nut", the head opens at once.
CLOSE F TYPE  Manual Rotate the handle on the front-side until the clutch to be close.
 AUTO <CNC Turrent Lathe> Rotating the handle until the clutch to be close, with pushing by actuator, or with reaversing the head and press the handle to obstacle. Handle can be modified with using bearings.
G TYPE  Use the moment of the head rotation  Increase the head's turning speed extensionally
 Use the "G-TYPE Closing System" Attach the "York" with braking shoe, and reduce the rotating speed of head's front side while the head turning until its clutch to be closed.
R TYPE  In case the head fixed / work piece turning Turn the handle until the clutch to be close.
 In case the head turning / work piece fixed Slow down the head rotation with pushing the "York"until the head to be closed.

*Only significant sizes are indicated above. Please freely inquire for the other sizes and thread standard. special rolls including "Trapezoid thread" "Burnishing roll" and more are provided.   

          Thread Rolls of ALCO has basically 1K (one thread0 of incomplete thread at the approaching side as its standard.
          Specialized rolls as below are also provided other than standard.
          - 2K ROLL
          * The duration of roll can be improvedby increasing the incomplete gap.          - 0.6 K ROLL
          - 0.3 K ROLL
          * It is also possible to reduce the incomplete gap. However, the duration will be get shorter as the gap increaseing .
