Benefits of technology
[0005]An object of the present invention is to provide a device for cooling tool holders with shrink fit chucks, said device being versatile for use with all kinds of tool holders while simultaneously facilitating more efficient cooling of several tool holders, particularly in direct succession.
Problems solved by technology
The disadvantage of these heat sinks is that adapting them to different shrink fit chuck dimensions is very difficult and often thermally ineffective and therefore a plurality of heat sinks must be kept available for the different shrink fit chucks.
To be sure, the cooling device is highly versatile for use with all kinds of shrink fit chucks, but such a cooling device is unsuitable for cooling several shrink fit chucks in direct succession, especially in an automated process.

Embodiment Construction
[0030]The inventive cooling device 1 shown in a purely schematic plan view in FIG. 1 comprises a container 2, inside of which are arranged a feed station 3, a cooling station 4, a drying station 5, and a transfer station 6. Outside the container 2 connecting to the transfer station 6 is a parking station 7, which is capable of receiving two tool holder receptacles 8a, 8b. At the feed station 3 and the transfer station 6 are doors 9, 10, which are provided for closing the container 2 during operation of the cooling device but which can however be opened for loading and transferring the tool holder receptacles 8a, 8b, 8c, etc.
[0031]For transporting the tool holder receptacles 8a, 8b, 8c, etc. inside the cooling device 1 is provided a means for transporting 11 in the form of a chain with dogs. Inside the container 2, the chain 11 runs in a first transport direction and branches inside the transfer station 6 into a transport direction perpendicular to that. In this way, as clearly shown...

Abstract
The invention relates to a method and a device (20) for cooling tool holders comprising shrink fit chucks, said tool holders beings received in a tool holder seat. The invention provides an especially efficient and above all completely automatable cooling system which allows a successive cooling of a plurality of tool holders (36). The cooling device (20) is very economical and can be shaped in such a manner as to be perfectly adapted to the space available and to already present shrink-fit devices (42).
Description
FIELD OF THE INVENTION[0001]The present invention relates to a device and a method for cooling tool holders with shrink fit chucks.BACKGROUND OF THE INVENTION[0002]Tool holders with shrink fit chucks come in all variations. They serve to clamp piping, turning, milling, reaming and grinding tools and the like by a thermally induced shrinking process. Usually, such shrink fit chucks are thermally heated by inductive shrinking devices, as a result of which the inside diameter of the shrink fit chuck is enlarged. With the inside diameter enlarged, a tool to be clamped is inserted into the shrink fit chuck, with the ratio of the inner diameter of the shrink fit chuck to the shaft diameter of the tool designed such that, on subsequent cooling of the shrink fit chuck, the tool is firmly clamped by the shrink fit chuck and cannot rotate.[0003]To accelerate cooling, cooling devices with ring-like heat sinks are often used, with the heat sink having an internal geometry adapted to the shrink ...
