DESCRIPTION OF THE MACHINE
Semiautomatic machine with hydraulic manipulation.
The machine is designed for cutting of material in vertical and angle cuts, angle cuts are possible to set
fluently from 60° right to 45° left.
It is suitable for piece production and small series production. The machine is so durable that it can be used
to cut a wide range of profiles and materials, including piece production and small series production.
The machine is designed to saw steel materials, but also non-ferrous and light metals. However, we
recommend consulting the manufacturer about this option.
No other materials may be sawn without approval from the manufacturer.
2.1
OPERATING CYCLE
After manual adjustment of the jaws the operator starts the cycle with a switch on the control panel. The
hydraulic cylinder of the vice grips the material and the saw starts working. The cutting speed of the arm is
controlled by a throttle valve. Arm and vice movements after cut following set users parameters. The vice
opens and the operator can handle the material.
2.2
CONTROL SYSTEM
The machine features a Mitsubishi PLC control system, which features an automatic feed control
BRP.
Control panel MITSUBISHI as standard equipment. It uses touch display and PLC, which enable
semi-automatic cutting (basic setting encluded) as well as communication with operator.
The control system displays information about the cutting process:
o
Cutting cycle indication,
o
indication BRP,
o
indication – blade tightening,
o
time of the cut,
o
loading of blade in amperes,
o
speed of the blade,
o
cutting times measuring,
o
list of error messages.
User´s setting:
o
autostop of hydraulic unit
o
mode of arm moving after end of the cut
o
mode time lag of shift speed
o
mode blade moving
o
mode jaw moving after cutting cycle finish
o
diagnostic of inputs and outputs
STOP function – cutting : it enables to stop cutting by pressing STOP button at any time. The Frame
goes up with the running blade without opening the vice.
Regulation of shaft speed (moving to cut) is manual and uses throttle valve placed beside control
panel. Automatic (safety) regulation of shift speed BRP. Principle: Machine will stop after exceeding
set loading (defined in ampers).
Extenally situated controlling panel - its position does not depend on the position of turntable position
during angular cuts. There is equipped with a safety button, which stops the saw. There is also a
feed regulator and buttons which controls the various available movements.
