Woodworking band saw machine is one of the main equipment of wood processing machinery. It uses a band saw blade to perform linear sawing on wood. Its main structure consists of five parts: machine base, fuselage, upper and lower saw wheels, saw card, and saw blade tensioning structure. This product has the characteristics of reasonable structure, reliable performance, stable operation, simple operation and high production efficiency. And a wide range of adaptation. The band saw machine can be used to cut square wood or round wood with corresponding plane when it is equipped with a workbench, and it can also cut the board or edge material to cut the shaped material for use, improving the utilization rate of wood. Larger logs. It is especially suitable for collective work and individual processing, and is an ideal woodworking machine for the wood processing industry and wood product manufacturing industry.
The technical specifications of woodworking band saw machines are different, but the structure is similar. The working principle is basically the same as that of material band saws. Now take the MJ316 machine tool as an example to introduce its structural characteristics. MJ316 joinery band saw machine is mainly composed of machine base (body), upper and lower saw wheels, work surface, adjusting hand wheel, saw card, brake device, motor and other components. All transmission parts of the machine tool are sealed to ensure safe operation. The machine base, the upper and lower saw wheels, and the work surface are made of cast iron. Two saw wheels with the same diameter are installed above and below the fuselage, respectively. The upper saw wheel can be moved up and down in order to load and unload the saw blade and adjust the tension of the saw blade. The lower saw wheel is a driving wheel and is driven by a pulley.
In order to reduce the wear and noise of the saw blade and saw wheel, a layer of belt is wound around the rim of the saw wheel. The work surface is directly mounted on the fuselage, with a gap in the middle for the path of the saw blade. The saw card is attached to the left side of the table, and the table can be tilted at an angle of 40o. In order to prevent the saw blade from swinging left and right during sawing, a saw clip is installed below and above the table top. The lower saw card is directly installed below the work surface, and the upper saw card is installed on the body, which can be moved up and down. There is a pulley behind the upper saw card. When the saw blade runs backwards, it plays a limiting role and does not cause the saw blade to fall. The machine uses a method of centralized discharge of sawdust to ensure the cleanliness of the work place.
The main structural feature of small woodworking band saws is the use of two saw blades, namely the main saw blade and the scribe saw blade. When cutting, the scribe saw is cut in advance to ensure that the edge of the cutting edge will not tear when the main saw blade is cut, so as to obtain good cutting quality. Scribing saw blades have a small diameter, usually around 120mm, and are driven by a separate motor. The speed of the saw blade is generally above 9000r / min, and the cutting speed is generally 56-60m / s. It is required that the scribe saw blade and the main saw blade are aligned in the same vertical plane. Driven by the main motor through a V-belt. According to the process, it can be divided into: large band saw, resection band saw machine and joinery band saw machine.
