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.
