Method and apparatus for manufacturing radiating ceiling plates and such radiating ceiling plates

摘要

The tubes (2) enclosed by the radiation plate (1) convey the heating or cooling media. A press tool used has a sub-tool (6) fixable to a press table comprising a locating part (6.2) movable relatively to a basic part (6.1) in a press direction and at least one tube holding part in a recess of the locating part (6.2), together with an upper tool (7) arranged on the press plunger (8). At least one central plunger (7.2) presses the radiation plate (1) on the tube (2) in the area of a tube holding part and two tongs plungers (7.3) are laterally arranged to the central plunger and on lowering of the upper tool on to the lower tool cause the radiation plate to bend around the tube.
