Temperature transfer in assembly technology - provides controllable temp transfer over given, spatially defined temp transfer sections

摘要

Temperature transfer from a temp. transfer unit (2) to a workpiece (4) takes place only over given transfer sections (7) to achieve given dimensional changes. The relative position of the transfer unit and workpiece is defined, and the temp. over the temp. transfer sections (7) is controlled by means of a temp. control unit. The temp. transfer is determined by the area and type (point, line etc.) of contact between the temp. transfer unit (2) and the workpiece (4). Heating of the workpiece takes place by means of continuous or pulsed radiation (infrared, laser, etc.), while cooling is effected with the use of air or water baths, or with the use of coils or similar devices carrying cooling liquid. The appts. (1) has at least one temp. transfer unit (2), which, in its working position (6), is positionable relative to a workpiece (4). The transfer unit partially mates with the workpiece, and is provided with at least one temp. transfer section. The appts. includes spring elements for pressing the temperature transfer unit, which is rapidly interchangeable, against the workpiece. USE/ADVANTAGE - In assembly technology. Energy savings are obtd. through controlled temperature transfer between the transfer unit and workpiece.
