Device for cleaning the inner corners of window or door frames

摘要

A device for cleaning the inner corners of window or door frames fabricated from butt-welded profiled bars is mounted on a corner-cleaning machine. A horizontal carriage (2) of the corner-cleaning machine carries, in addition to the devices (6, 7) for cutting off the weld beads (5a, 5b) on the visible surfaces of the frame corner (5) and a milling cutter (9) for the outer corner of the frame, also a vertically movable vertical carriage (10) on which is arranged a milling and cutting device (12) for machining the inner corner of the frame. A stop means (15) mounted on the vertical carriage (10) bears on the inside of the tail (5e) of the frame corner (5) and determines the vertical adjustment. All profiled members of a series of profiles whose tails (5e) are in each case identical but which are located at different points on the profile can be machined without any special adjustment measures (Fig. 1). <IMAGE>
