Adjusting Stroke

Length

The stroke length of the beam and attached tool- ing is adjusted by moving the position of the limit stops. The typical benefit of adjusting the stroke length is to shorten the distance the tooling moves away from the workpiece to decrease the amount of cycle time needed between cuts.

Keep in mind that most tooling requires that the die or punch passes entirely through the workpiece.

Turn the machine off, then use a 10mm wrench to remove the hex bolts and the access panel to the limit stop assembly. Become familiar with the dif- ferent parts of the assembly, as shown in Figure 42, and their descriptions listed below.

NOTICE

Damage to the machine, tooling, or stock that is a result of incorrect settings made to the limit stops will not be covered under warranty. DO NOT change the factory set- tings of the limit rings.

C.	Limit Bar: Moves with the beam and enables
	the limit stops to engage the limit switches.
D.	Limit Stop Set Screw: When loosened,
	allows the limit stop to be re-positioned.
E. Limit Stop: Engages the limit switch as the
	limit bar moves with the beam.
F.	Punch Limit Switch: When engaged by the
	left limit stop, reverses the beam movement
	and lifts the punch up and away from the
	punching station (in Punch mode), or stops
	the beam (in Notch mode).

G. Notch Limit Switch: When activated by the

right limit stop, reverses the beam movement

and lifts the top die up and away from the

notching station (in Notch mode), or stops

the beam (in Punch mode).

H. Limit Bar Support Bracket: Provides sup-

port for the limit bar as it moves from side to

side.

Figure 42. Limit stop assembly.

A.Beam Attachment: Moves the limit bar and limit stops from side-to-side with the move- ment of the beam.

B.Limit Ring: Stops the limit stop from moving past the maximum outbound setting. The limit ring is set at the factory and should not be moved.
