A low-stress tensioning and drive system for band saws.

Abstract

This invention relates to an innovative tensioning and drive system aimed at improving the performance and efficiency of band saws. The system incorporates a special mechanism that provides drive to the saw by applying pressure to pulleys while creating the necessary tension on the band. The band tensioning and drive system utilizes one or more surfaces with low friction and low point pressure; these surfaces may consist of a structure with water channels or wheels (8) surrounded by multiple flexible materials placed along a back plate (2), depending on different configurations. Water channels prevent wear and increase the durability of the saw blade by aquaplaning through hydrodynamic and / or hydrostatic pressure on the surface, while the wheels (8) surrounded by flexible materials minimize point pressures and friction during movement, preventing wear on the mechanism and the saw blade. The system ensures long service life and superior cutting performance in band saws.

Multi-wire cutting developed for cutting into sheets. It is related to the machine. The tension of each diamond wire is independent. It has a tensioning system that can be adjusted accordingly. 3 The tensioning system generally consists of pulley sets and hydraulic systems. for lubrication of cylinders, guide and sliding elements It includes niches. This system controls the tension of each diamond wire. by adjusting the wire efficiently during the cutting process. It enables it to function. Thus, it relieves excessive tension. 5 wire breakage or looseness that may result from Cutting errors that may result from this are prevented.
