Schweißvorrichtung für rechteckige Rahmen, insbesondere Fensterrahmen

摘要

The invention relates to a device for producing rectangular frames, in particular window frames, from plastic, comprising four slides which can travel in relation to one another in a horizontal plane on cross slides, with a table divided into two supporting plates by a gap running at an angle of 45 DEG , with two outer stops arranged at right angles with respect to each other and receiving a welding shim, with a clamping unit and a welding unit and also comprising a raiseable transporting device, which carries the welded frames away in a horizontal position. To weld two frames simultaneously and in a single operation without excessive extra effort, and at the same time permit unhindered insertion of all the profiled pieces for forming the frame, above each table (4) there is arranged a raiseable and lowerable support plate (7) divided into two supporting plates (7a, 7b) by a gap (9) running at an angle of 45 DEG , with two outer stops (13) arranged at right angles with respect to each other and receiving a welding shim (12), at least the supporting plates (7a) located on the insert side of the device and the outer stops (13) assigned to the same are able to be horizontally swivelled separately with their welding shims (12), and each cross slide is assigned a stop (15) which can be brought into the gaps (9) above one another of table (4) and support plate (7), and the...
