BANDSAW Russian patent published in 2021 - IPC B23D55/08 

FIELD: machine tool engineering.

SUBSTANCE: invention relates to machine tool engineering and in particular to devices for bandsawing machines for cutting various materials. The bandsaw has a saw frame, two discs located on the saw frame, a bandsaw stretched on the discs, stabilizing elements for damping the vibration of the bandsaw and two guides for the bandsaw. Each of the stabilizing elements consists of two rollers, one of which is made of metal and the other one is made of caprolon. The guides are installed in a single block on the saw frame, and each stabilizing element contains an additional rotary mechanism installed on the saw frame, made with the possibility of turning through an angle of 45-135° relative to the plane of the workpiece in the cutting zone. On the mating surfaces of the movable and stationary elements, slots with a height of 3 to 5 mm are additionally cut into a triangular profile. The axles are made of a stepped shape and the free ends are interconnected by means of a connecting plate installed at a distance from the end face of the rollers with the possibility of changing the standard sizes of bandsaws and fixed on the axles by means of lock washers and nuts.

EFFECT: increase in the rigidity and stability of the tool.
