Main structure
The machine tool consists of a base part, a guide part, a main
transmission system, a saws tensioning device, a feed positioning
system, a hydraulic system, an electrical system, a protection
device, and a cooling system; A series of command actions are
performed through the cooperation of each part to complete the
material feed, positioning and sawing.
1 Base section
The entire base is a box-shaped structure welded by A3 steel
plates. The left side of the base is a hydraulic tank, and the
right side is a cooling tank. After the base is welded, it is
subjected to vibration aging to remove the welding internal stress.
2 Orientation
The guide part is divided into saw beam guide and saw bar guide
part. The guide part of the saw beam is composed of a large
diameter column and an auxiliary square column. Through the lifting
cylinder, the action direction of the saw cutting feed and the
cutting knife is made. The reasonable structure layout makes the
sawing guide more stable and the accuracy higher. Saw guide
It consists of a pair of guide arms and a guide head. The guide
head distorts the saw bar around the edge of the saw wheel into a
vertical state with the work table, making the cut material cut
vertical.
3 Main transmission system
The main transmission system consists of a worm gear reducer, a
triangular belt wheel, and a main motor. The worm wheel is made of
tin bronze materials and is processed on a precision roller hob
using a precision worm hob. After harrowing, the worm is ground in
a precision worm grinder with high surface finish and high
precision. The box body adopts HT250 cast iron, which guarantees
the processing accuracy with the special boring mode, and the worm
wheel has a long service life. The output end of the worm wheel box
is connected with the active wheel, and the slave wheel is rotated
by a saw bar around the rim to perform rotary cutting.
4 Saw bar tensioning device
It consists of tensioning handle, Zhangjinsi rod tensioning drawing
board, tensioning sliding block, hollow adjusting screw, etc.. By
tightening the wire bar adjustment, the saw bar can be tightened
and relaxed and replaced. It is also possible to adjust the angle
relationship between the saw wheel and the beam plate through
hollow adjusting screws.
2.5 Material feed positioning system
The feed positioning system consists of a feed bed, a cylindrical
guide rail, a drum, and a sawing machine. When it is sent to the
sawing setting data, the feed is stopped and sawn. One-time feed
trip: 420mm,
6 Hydraulic system
The hydraulic system consists of a hydraulic motor, a pump, an
electromagnetic valve, a speed regulating valve, an oil cylinder, a
tubing, and a fuel tank. The required operation is completed
through the output of the electrical system.
7 Electrical systems
The electrical system consists of Transformers, contactors, touch
screens, PLCs, relays, proximity switches, wires and switches. By
entering data and parameter settings into the touch screen, and the
hydraulic system, to complete a series of sawing action
requirements.
8 Protective devices
The protective devices are divided into safety protection and
electrical system protection. The safety protection devices include
saw wheel Shields, belt wheel Shields and other facilities. These
facilities are facilities for the protection of personal safety and
must not be demolished at will. Electrical system protection
includes the main circuit overload protection, motor overload
protection, saw bar break stop protection.
9 Cooling system
The cooling system is divided into saw-cut cooling and hydraulic
oil cooling. By pumping the coolant into the cooling line, the saw
strip is cooled and the sawdust is washed so that it is sawn more
smoothly. Hydraulic oil is cooled by the hydraulic oil flowing back
through the tubing through the cooler and then back to the
hydraulic fuel tank, so that the oil temperature remains stable and
does not rise during work, so as to ensure that the hydraulic
system is working normally and steadily.
