Brief introduction of band sawing machine related knowledge

Metal band saws are machine tools used for sawing various metal materials. They are mainly divided into horizontal band saws and vertical band saws.

The main components are: base, bed, column, saw beam and transmission mechanism; saw blade guide device; workpiece clamping device; saw blade tension device; feeding mechanism (automatic series); hydraulic transmission system; electrical control system; lubrication and cooling system .

Band saws are mainly used for sawing various alloys and metal materials such as carbon structural steel, low alloy steel, high alloy steel, special alloy steel, stainless steel, acid-resistant steel, etc. With the development of saw blade technology, ordinary glass, single crystal silicon, The stone blank gradually enters the sawing menu.

　　According to the structure, it is divided into horizontal band sawing machine and vertical band sawing machine. Horizontal type is divided into scissors type, double column and single column type band sawing machines; vertical type can be divided into pulley and sliding table band sawing machines;

　　 is divided into manual type and automatic type according to use operation;

　　 According to the degree of automation of the controller, it can be divided into manual type, semi-automatic type, fully automatic type, and automatic type is divided into PLC logic control (numerical control) and travel switch control, etc.;

　　According to the cutting angle requirements, it is divided into angle sawing machine (can saw the angle of 0-60 degrees) without angle, that is, 90 degrees vertical cutting.

　　 System function of band sawing machine:

　　Hydraulic transmission system consists of a hydraulic circuit composed of pumps, valves, cylinders, tanks, pipelines and other auxiliary parts. The saw beam is lifted and lowered and the workpiece is clamped under electrical control. Through the speed control valve, the stepless speed regulation of the feed speed can be implemented to meet the needs of sawing workpieces of different materials.

The electrical control system consists of a control loop composed of an electrical box, a control box, a junction box, a travel switch, an electromagnet, etc., used to control the rotation of the saw blade, the lifting of the saw beam, the clamping of the workpiece, etc., to make it follow a certain working procedure Realize the normal cutting cycle.

　　 The lubrication system must be lubricated according to the lubrication parts of the machine tool (wire brush shaft, worm gear box, active bearing seat, worm bearing, lifting cylinder upper and lower shaft, sliding surface clamping screw of movable vise) before starting. The worm gear and worm in the worm gear box are lubricated by a No. 30 oil bath, which is injected from the oil plug hole on 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 on the upper side of the oil mark. Between the lower limit. The oil should be changed after one month of 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 the tension of the saw blade, and the tension of the saw blade must be strictly controlled during use.
