11.5.4 peeling electronic cam Profile
Brief introduction
Electronic cam is fundamentally a function of the cam computer-implemented, the entire
system generally consists of two parts, hardware and software. The system hardware includes a
microprocessor, a memory device, D / A converter, a controller and actuators. The encoder signals
the microprocessor to obtain from the storage device corresponding to the displacement signal
calculated from the formula or a displacement value, then the input of the cam displacement value
D / A converter, the converted signal processing to achieve the corresponding actuator is driven by
the controller exercise.
Applications
Electronic cam having a wide range of applications in the mechanical industry material field
cut to length, for example cut to length steel, wood
Material for coil, aluminum strip for cutting fixed-length, the corrugated crop, laterally
sealing the packaging bags slitting, punching,
Embossing. Electronic cam application flying shear, peeling, cut recovery, and stop
discharging collectively called shear cut the wheel, called transverse.
Relative to the longitudinal cross terms, refers to vertically cut the material in the material
transport direction, cutting length is generally fixed.
(1) Peeling
In this mechanism, mounted on a roller (or the number of the shearing blades), driven by
movement of the shearing blades rotating roll, the roll motion of the severing one week once (or
several times).
(2) Flying Shear
And peeling in the same definitions section, but in some special shear, for example shear
plate, the eccentric shaft
Mounting the blade holder about the fixed shearing blade rotary movement, to achieve the
purpose of the cut to length [5].
(3) to recover shears
Cut recovery is characterized by: the sync area set pulling speed of the shearing member and
feeding same feed rate, shear motion in the sync area is completed, and different lengths of the cut
by adjusting the speed to accommodate non-synchronous zone. Chase cut and peeling, the biggest
difference is flying shear: Shear chase reciprocating motion, and peeling, flying shear is a
movement in the same direction. Another application of shear to catch flying saw, flying saw
cutting means that when synchronization feed mechanism, the material for cutting.
(4) stop cutting
And said cutting different ways, stop feeding the control shaft shear, rapid feed in the
shearing blade is lifted off time and cut to stop. Several different from the previous, stop feeding
the cut feed gap, so that the shear stop control simple, low processing efficiency.
