Familiar With The Machine Tool Structure Of The Band Saw Machine

The technical specifications of band saws are different, but their structures are similar. The working principle is basically the same as that of band saws used for material production. Now, taking the MJ346A machine tool as an example, its structural characteristics will be introduced.
The MJ346A fine woodworking band saw machine is mainly composed of a machine base (body), upper and lower saw wheels, worktable, adjustment handwheel, saw ratio, braking device, electric motor and other components. All transmission parts of the machine tool adopt a sealed structure to ensure operational safety. The machine base, upper and lower saw wheels, workbench, etc. are all made of cast iron. Two saw wheels with the same diameter are installed above and below the machine body, respectively. The upper saw wheel can be adjusted up and down to facilitate the installation and removal of saw blades and the adjustment of saw blade tension. The lower saw wheel is the driving wheel, which is transmitted through a belt pulley. In order to reduce the wear and noise of the saw blade and saw wheel, a layer of belt is wrapped around the rim of the saw wheel. The workbench is directly mounted on the machine body, with a gap in the middle serving as a passage for the saw blade. The saw is attached to the left side of the worktable, and the worktable can be tilted at a 40o angle. In order to prevent the saw blade from swinging left and right during sawing, there are two saw clips installed below and above the worktable. The lower saw clip is directly installed below the worktable, while the upper saw clip is installed on the machine body and can move up and down. There is a pulley behind the upper saw card, which acts as a restriction when the saw blade runs backwards, preventing it from falling off. The machine tool adopts the method of centralized discharge of sawdust to ensure the cleanliness of the work site.
