Woodworking band saw machine is a sawing machine that uses a ring-shaped endless band saw blade as a saw, and is wound on two saw wheels to make a one-way continuous linear motion to cut wood. It is mainly composed of bed, saw wheel, upper saw wheel lifting and tilting device, band saw blade tensioning device, saw blade guide device, worktable, guide plate, etc. The bed is made of welded cast iron or steel plate.
The saw wheel is divided into a web type saw wheel and a web type saw wheel; vertical saw generally the lower saw wheel is the driving wheel, and the upper saw wheel is the driven wheel. The weight of the upper saw wheel should be 2.5 to 5 times lighter than the lower saw. The cutting speed of band saw blade is usually 30~60m/s. The upper saw wheel lifting device of woodworking band saw machine is used for loading and unloading and adjusting the elasticity of the band saw blade; the upper saw wheel tilting device is used to prevent the band saw blade from falling off the saw wheel during sawing. The band saw blade tensioning device can give the upper saw wheel elasticity to ensure the stable tension of the band saw blade in operation; the old type adopts a spring or lever hammer mechanism, and the new type adopts a pneumatic and hydraulic tensioning device. The guide device is commonly known as the saw card to prevent the band saw blade from twisting or swinging during sawing; the lower saw card is fixed at the lower end of the bed, and the upper saw card can be adjusted up and down along the vertical slide; the saw card structure has a roller type and a slider type , The slider type is made of hardwood or wear-resistant plastic. Band saws are widely used in the wood industry and have a wide range of models. According to the process, they can be divided into: large band saws, resection band saws and joinery band saws; according to the placement of the saw wheel: vertical and horizontal The vertical and the inclined type are divided into: right type and left type; according to the installation method of the band saw machine: fixed and mobile; according to the number of combination: ordinary band saw machine and multi-band saw Machine waiting.
