Abstract
A device for cooling a shrink-fit chuck with a cooling head, which contains a cooling attachment that can be mounted on the shrink-fit chuck and an intake tube connected to the cooling attachment for the drawing of air at an input of a passage opening in the cooling attachment. In order to make possible a limited noise emission, the cooling head includes a cooling air feed at least partially insulated by a sound insulation device to supply air to the input of the passage opening on the cooling attachment.
Claims19
A cooling device for cooling a shrink-fit chuck, the cooling device comprising:
- a cooling head having a cooling air feed;
- a cooling attachment configured and arranged for mounting on at least a part of the shrink-fit chuck;
- and
- an intake tube connected to the cooling attachment, the intake tube configured and arranged for intake of air at an input of a passage opening in the cooling attachment;
- wherein the cooling device further includes a sound insulation device configured and arranged to surround the intake tube at least partially insulate the cooling air feed to dampen sound resulting from the cooling air feed supplying air to the input of the passage opening;
- wherein the cooling air feed has two feed lines for air flow in a flow direction, the two feed lines including a first feed line and a second feed line connected to the first feed line, the second feed line configured and arranged downstream the first feed line such that air flows through the first and second feed lines in the same flow direction which is opposite to the direction of flow in the intake tube.
