BANDSAW MACHINE Russian patent published in 2018 - IPC B23D55/08 

FIELD: machine building.

SUBSTANCE: invention relates to machine tool building, namely to devices for bandsaw machines for cutting various materials. Bandsaw machine comprises a saw frame, two discs, one of which is driven, and the other one is tensioned, located on the saw frame, a band saw, stretched on the mentioned discs, stabilizing elements for damping the vibration of the band saw and two guides of the band saw, which turn it relative to the plane of the workpiece in the cutting zone and mounted on the saw frame. Each of the stabilizing elements consists of two rollers, one of which is metallic, and the second one is made of Caprolon. Guides are installed as a single unit on the saw frame. Each stabilizing element further comprises a turning mechanism, mounted on the saw frame, each of which is made with the possibility of rotation at an angle of 45–135° relative to the plane of the workpiece in the cutting zone in the opposite direction relative to each other, providing twisting the band saw and consisting of movable element and element fixed on the saw frame interconnected by means of a bolted joint. Bolt joint is placed in a through-hole, cut along the parabola's trajectory on the movable element, which is communicated with the rollers by means of axles. Triangular profile slots with a height of 3 to 5 mm are additionally cut on the mating surfaces of the movable and fixed elements.

EFFECT: result is the increased rigidity and durability of the cutting tool by reducing the vibration of the band saw and the decreased intensity of sound radiation during cutting at the source.
