band sawing machine;
according to the operation, it is divided into manual type and automatic type;
according to the automation degree of using the controller, it can be divided into manual type, semi-automatic type and full-automatic type, and the automatic type can be divided into PLC logic control (numerical control) and stroke on-off control, etc.
according to the requirements of cutting angle, it can be divided into angle sawing machines (which can cut at an angle of ~6 degrees) to cut vertically without angle, that is, 9 degrees.
System function of band sawing machine:
The hydraulic transmission system is a hydraulic circuit composed of pumps, valves, oil cylinders, oil tanks, pipelines and other auxiliary parts, which can lift the sawing beam and clamp the workpiece under electrical control. The stepless speed regulation of feed speed can be implemented through the speed regulating valve to meet the sawing needs of workpieces with different materials.
the electrical control system is a control loop consisting of an electrical box, a control box, a junction box, a travel switch, an electromagnet, etc., which is used to control the rotation of the saw blade, the lifting of the saw beam, the clamping of the workpiece, etc., so as to realize the normal cutting cycle according to certain working procedures.
before starting, the lubrication system must be oiled according to the lubrication parts of the machine tool (wire brush shaft, worm gear box, active bearing seat, worm bearing, upper and lower shafts of lifting cylinder, sliding surface clamping screw rod of movable vice). The worm gear and worm in the worm gear box are lubricated by 3 # engine oil oil bath, and injected from the oil plug hole at the upper part of the worm gear box. The box surface is equipped with an oil mark. When the saw beam is at the lowest position, the oil level should be between the upper and lower limits of the oil mark. The oil should be changed after one month's use, and then every 3-6 months. The lower part of the worm gear box is provided with an oil drain plug.
the saw blade tensioning mechanism is responsible for tensioning the saw blade, and the tensioning force of the saw blade must be strictly controlled during use.
