Once the cut is complete, the inlet port fluid pressure decreases. The clamp return
spring forces the piston ram inward and the relief valve opens to channel fluid out
of the inlet port. Once the fluid pressure decreases past the activation setting of
the control valve, the valve opens to channel excess fluid out the suction hose.
f. Retarding valves. Located in the plumbing to the clamp cylinder and the
clutch ram. During the upward clamp movement, the valve allows hydraulics to flow
back to the reservoir at an even pressure to allow smooth return of the clamp. When
hydraulics are flowing to the clutch ram, the other retarding valve allows for a
smooth and even flow of hydraulic fluid.
mechanical components of the paper cutter. (Refer to Table 5-3 for the sequence of
operation of circuitry in response to basic operations.) It is comprised of:
a. Power connection box. Supplies 220 V ac, three-phase power to machine. The
machine is hard-wired to a breaker/fuse box and protected by a 25 amp fuse.
The power connection box contains a terminal block where the input lines, labelled
R, S and T, and a ground wire are connected. Wires connected to the other side of
the terminal block carry the input power to the main distribution PC card HP via the
main power switch.
