Briefly introduce the band saw machine

A circular endless band saw machine  is used as a sawing tool to perform a one-way continuous linear motion on two sawing wheels to saw the sawing machine. Mainly by the bed, saw wheel, saw wheel lifting and tilting device, band saw tensioning device, saw blade guide device, table, guide plate and other components. The bed is made of cast iron or steel plate welded.

The saw wheel is divided into a strip-type upper saw wheel and a web-type lower saw wheel; the lower saw wheel is a driving wheel and the upper saw wheel is a driven wheel. The weight of the upper saw wheel should be 2.5-5 times lighter than the lower saw. The cutting speed of the band saw blade is usually 30~60m/s. The upper saw wheel lifting device 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 when sawing. The band saw blade tensioning device can give the upper saw wheel elasticity to ensure the stability of the band saw blade in operation; the old type uses the spring or the lever weight mechanism, and the new type uses the pneumatic and hydraulic tensioning device. The guiding device is commonly known as a sawing card to prevent the saw blade from twisting or swinging when sawing; the lower sawing card is fixed at the lower end of the bed, and the upper sawing card can be adjusted up and down along the vertical slide; the sawing structure has a roller type and a slider type The slider type is made of hardwood or wear-resistant plastic. Band saw machines are widely used in the wood industry and have a wide range of models.
