The band saw machine uses an endless band saw blade as a saw A saw machine that revolves around two saw wheels and makes a linear motion at intervals to cut wood. The band saw machine mainly consists of a bed, a saw wheel, an upper saw wheel lifting and tilting device, a band saw blade tensioning device, a saw blade guide device, a workbench, a guide plate, etc. The bed is made of cast iron or welded steel plate. What types of band saws are there? The editor above will introduce you to the classification and principle knowledge of band saw machines.

Horizontal band saw machine has an upper saw wheel and a lower saw wheel, usually the lower saw wheel It is an immediate wheel, and the upper saw wheel is an automatic wheel. A thin steel strip with saw teeth on one side is hung on this pair of saw wheels - the band saw blade. When the saw wheel rotates, the band saw blade also gradually rotates, so the saw teeth on the saw blade After a while, Yu moved rapidly, and the wood came into contact with it and was sawed open by it.

Woodworking band saw machine: The woodworking band saw machine is mostly small. It uses the power of the machine to replace part of the manual labor of sawing wood when workers are making various appliances, improving production efficiency. The structure of the band saw machine for woodworking is relatively simple, and the requirements for operating skills are by no means low. The saw wheel diameters are 610mm and 914mm, which are commonly used band saw machines for woodworking. The band saw used in the lumber factory is different from the nature of the operation in the woodworking factory - cutting a huge log into square logs or boards may be more expensive than the woodworking factory converting it into square logs or boards. The requirements for sawing the board into large-sized square logs or wooden boards are different, so the band saw machine used for lumber production has a strong mechanism, relatively small horsepower, and low requirements for operating technology. According to the structure and performance of the band saw machine, it can be divided into: a band saw machine with a workbench (large band saw); a band saw machine with a trolley, which is also a sports car band saw machine; and a band saw machine with both a workbench and a trolley. machine.

A band saw machine with a workbench places one end of the wood to be processed on the workbench, and uses human power to hold the other end. Make the wood contact the saw blade and push it forward at intervals to saw it according to the required specifications. There is an adjustable baffle on the workbench. This baffle is called a "saw wall". Turn the handle wheel on the screw to adjust the distance between the saw wall and the saw blade according to the required size. One side of the wood is tightly sawn against the wall, and the other side is pushed forward to be sawed according to the required size. This type of band saw machine belongs to the category of small band saw machines in lumber factories. It is not suitable for processing relatively small logs, so it is suitable for large square wood or plates processed by large band saw machines. The saw wheel diameters are usually 813mm, 914mm, 1067mm, and 1118mm.
