Machine cutting-out wall section from end of box-tubing, includes blade in carrier supported during cutting stroke for rotary- rather than linear motion,

摘要

The blade carrier (5) is supported for rotation such that the tubular hollow body (3) and the cutting tool (4) inside it, execute a turning movement during the cutting operation. The axis of rotation (8) of the blade carrier is arranged in a mounting (7). The cutting blade (6) is located in a region of the cutting tool remote from the axis (8). The blade (6) forms a cutting gap with a lower cutter (9) of the matrix (10). The blade contour follows the geometric shape of the cut-out.
