Mechanical Shear with Automatic Gap Control
For Use in Cut-to-Length Line
Strip Thickness: 0.060" - 0.500" (Mild Steel)
Blade: Carbon Steel Knife, Single Rake
Blade Gap Control: Motorized
Lubrication: Centralized and Manual Grease
Kick out Roll: Hydraulic Gear Motor
The Shear consists of the main housing, over driven clutch/brake
flywheel arrangement, camshaft, sliding frame, top and bottom blade
holder, gap control and kick-out roll assembly.
The main housing and base are of fabricated steel construction. The
housing incorporates cam rollers to support and guide the sliding frame
in its travel. The main housing also supports the camshaft, clutch and
brake assembly and drive.
The upper and lower blade holders are of heavy steel plate construction,
machined to accept the blade. The (upper) sliding frame is connected
to the camshaft via pitmans running in large bronze bushings.
The alloy precision machined camshaft is supported in roller bearings in the
housing and, in turn supports the clutch-brake and flywheel assembly. The
camshaft drives the pitmans which give the vertical motion to the sliding
Automatic Gap Control:
The blades will automatically be set, by input from the PLC, to the
proper clearance for the material being processed. An operator override
The Flywheel is driven via vee belts and a pulley mounted on the drive motor.
The flywheel has the clutch/brake assembly mounted to it which when actuated
will turn the camshaft to initiate the cut cycle.
Pinch Rolls are mounted ahead of the shear blades to assist transporting the
tail of the strip through the shear. The rolls run in grease lubricated
bearings and are supported in fabricated steel housings.
The lower roll is full width and the upper roll partial width, pivoted up
and down through a pneumatic cylinder. The lower roll is driven via a hydraulic
This shear is controlled by a rotary electronic limit switch blade position
system. The cut signal when received from the measuring control system
will initiate the shear cycle. After the cut, the shear will cycle back
to its ready position.
