Machine to mill and drill the joining heads of wood or wood-metal profiles in the manufacturing of frames, in particular door and window frames

摘要

The invention consists in a drilling and milling machine which allows the drilling and milling of joining heads of wood and wood-metal profiles in manufacturing door/ window frames. The machine operates simultaneously on two miter cut profile sections so that the milling and drilling on both the joining heads match perfectly when they are coupled by means of positioning dowels inserted in the millings and of fixings inserted in two diameter holes. The machine consists of a structure bearing the positioning assembly (1) for two profile sections to be coupled, the two piece locking cylinders (6) and (9), the mill-motor assembly (11) and (8) mounted on roll-off horizontal sliding guide (7) moved by an extension cylinder (2), the lifting cylinder (3) which moves along the vertical axis the mill-motor assembly and also acts as its oscillating fulcrum, and two electric motors mounted on roll-off horizontal slide guides (4) and (12) which drive bits (4) and (10) to drill two diameter holes perpendicularly to the miter cuts.
