Title: Plastics window frame weld cleaner - has tool support with contour miller and milling tools set according to the frame profile
Inventor: EISENBACH BERND
IPC: B27B33/20
Filed: 1990-06-06
Abstract: Appts. to clean window frames, is constructed from welded plastics profile sections, to remove surplus and projecting material at the welds, has a disc-shaped contour miller (5) at the tool carrier (4), generally parallel to the plane of the window frame, with an axial gap from at least one milling tool (2). At least two milling tools (2,3) are located above each other on a common shaft (6), parallel to the window frame plane, together with the contour miller (5), at the tool carrier (4) which also supports the motor-driven shaft (6). A control guides the tool carrier (4) to move the contour miller (5) round the outer corner contour of each frame (1) when in the operating position. The control has a sensor (7) at the tool carrier (4) to register at least one working surface (8) pref. at the working plane of the contour miller (5) when in the operating position at the outer contour of the frame (1). A profile identification unit (10) at the control moves at least one of the milling tools (2,3) or the disc-shaped contour miller (5) in the operating position using contacts (11,12) or sensors to register the frame (1) profile. The control system is pref. a computerised numerical control. The tool carrier (4) has a drill (13, 13a) at least at one free end of the shaft (6). The tool carrier (4) slides at right angles to the plane of the window frame through a support (15) running parallel to the frame plane on the base frame (14) of the appts.. Drives (22,23), operated by the control, push the tool and support carrier into their settings, using piston/cylinder units (22,23) operated by a pressure medium, or they are electrical systems with a step- or spindle-motor which can work at one of two speeds. ADVANTAGE - The appts. gives a reliable weld cleaning action and can be reset rapidly for a change of window frame, so that it can be prepared for the window frames most commonly processed.
