SHEAR ASSEMBLY

OPERATION

Push the SHEAR DOWN button to activate the shear cycle and cut material. IN CASE OF

AN EMERGENCY: Push the SHEAR UP button during the down cycle to immediately

send the shear up to the home position.

The shear is electrically activated and hydraulically driven.

The two Top Limit Switches and single Bottom Pressure Switch control the cycle of the shear.

The Top Limit Switches electronically lock out the drive system when the shear is in motion.

The Bottom Pressure Switch sends the shear back up once the set pressure is reached.

SHEAR ADJUSTMENTS

Bottom Shear Dies (Detail A - Figure 20)

1. Bottom dies should be adjusted 1/32” below the bottom corners of the panel. Loosen the (2)

“A” bolts on the left and right Front Vertical Plates. Loosen the (2) lock nuts on the (2)

Height Adjustment bolts “B”.

2. Tightening bolts “B” will lower the shear, and loosening them will raise it. Adjust each side

as needed to properly set the bottom dies to the correct spacing from the bottom corners of

the panel.

3. After adjustments have been made, tighten (2) “A” bolts and (2) Lock Nuts on Height

Adjustment Bolts “B”.

CHANGING ENTRY AND EXIT SHEAR DIES

(Figure 19 & Figure 20)

The Entry and Exit Shear Dies are specific to each roller set and must be changed when changing

profiles. Refer to the PROFILE CHANGEOVER PROCEDURE for instruction on changing dies.

ADJUSTING THE ENTRY AND EXIT SHEAR DIES

(Figure 19 & Figure 20)

1. The Male and Female entry and Exit Shear Dies must be adjusted to the proper distance from

the vertical legs of the panel. The outside vertical leg of the male and female Entry Dies

should be approximately 1/32” away from the outside of the vertical legs of the panel. The

Exit Dies should be slightly to the outside of the male and female Entry Dies so that after a cut

is made, the panel does not hang up on the Exit Dies.

2. Each Shear Die Holder is held in position by (2) “C” bolts passing through slotted holes at the

bottom edge of the holder, and threaded into the Entry and Exit Shear Plates.

3. Visually sight thru the male and female entry dies. Rough align them to the forming tool “line

of fire” by moving them side-to-side. If necessary, remove bolts “C” and slide the Die

Holders left or right until you find two mounting holes that will work for proper alignment,

then re-install bolts “C”. Tighten them just enough to hold the dies in position.

4. Jog the material through the machine and stop about 2 inches from the Entry Shear Dies.

Now re-sight the alignment of the Male and Female Dies to the actual legs of the panel and

move them accordingly to assure the panel will pass through without hanging up. Carefully

jog material through the shear dies. Final adjust Entry and Exit Dies as follows: The Male
