Abstract
A method for sawing a metal tube (3) or hollow section using a band-saw machine which has a stationary lower saw part (1) having a saw table (2) for placing and fixing a metal tube (3) to be sawn, and an upper saw part (4) which is movable in relation to the lower saw part (1) and which has a revolving saw band (5). The revolving saw band (5) via a feed motion (13) of the upper saw part (4), which is performed in relation to the lower saw part (1), penetrates the metal tube (3) and, for performing a saw cut, is guided through said metal tube (3). The feed motion is carried out substantially counter to the force of gravity.
Claims7
A method for sawing a metal tube or hollow section, comprising using a band-saw machine which has a stationary lower saw part (1) having a saw table (2) for placing and fixing a metal tube (3) or hollow section to be sawn, and an upper saw part (4) which is movable in relation to the lower saw part (1) and has a revolving saw band (5) equipped with a series of saw teeth (12), the revolving saw band (5) by a feed motion (13) of the upper saw part (4), which is performed in relation to the lower saw part (1), penetrating the metal tube (3) or hollow section and, guiding the saw band (5) through said metal tube (3) or hollow section for performing a saw cut, and carrying out the feed motion (13) substantially counter to a force of gravity.
A band-saw machine for sawing a metal tube or hollow section, comprising a stationary lower saw part (1) having a saw table (2) for placing and fixing a metal tube (3) or hollow section to be sawn, an upper saw part (4) which is movable in relation to the lower saw part (1) and which has a revolving saw band (5) equipped with a series of saw teeth (12), and an actuator (16′) that generates a feed motion (13) of the upper saw part (4) which is performed in relation to the lower saw part (1), so as to cause penetration by the saw teeth (12) of the saw band (5) into the metal tube (3) or hollow section, and to cause a saw cut, the actuator (16′) configured to lift the upper saw part (4) counter to a force of gravity and a vertical component of a cutting force generated during the saw cut.
