Embodiment Construction

[0014] figure 1 A first embodiment of the invention is shown. The induction coil 1 forms a magnetic circuit in combination with the field concentrator 3 , the sleeve section 2 of the tool chuck and the field conductor arrangement 4 , said magnetic field lines heating the sleeve section 2 of the tool chuck.

[0015] The sleeve section 2 thus forms a cooling channel 5 together with the coil housing 6 surrounding the coil 1 . For example, water flows through the cooling channel, and the water is usually mixed with anti-corrosion inhibitors. Also, any other suitable fluid may be used, for example a fluid like glycol or a gas or liquefied gas. The cooling channel extends between the coolant supply pipe 10 and the coolant discharge pipe 11 . When the tool chuck is inserted, the cooling channels are at least substantially sealed against the surroundings.

[0016] A section of said cooling channel 5 extends between the inner surface of the induction coil 1 , which is protected by...

Abstract

The present invention relates to a device for tensioning or de-tensioning tools, having a tool shaft in a tool chuck which has a sheath section open on the free end thereof and which is made of electrically conductive material, for receiving the tool shaft in a friction connection, having an induction coil which surrounds the sheath section of the tool chuck, to which preferably high-frequency alternating current can be applied, and which is designed as a ring or cylinder coil, wherein the device has at least one channel running between the inner peripheral surface of the induction coil and the sheath section of the tool chuck, through which flows a cooling agent which cools the sheath section of the tool chuck.

Description

technical field [0001] The invention relates to a device for clamping and / or unclamping a tool comprising a tool shaft arranged in a tool chuck, said tool chuck and said tool shaft being connected by means of a shrink way to connect. Background technique [0002] A device of this type is known, for example, from German patent application DE 10348880 A1, which describes in detail the basic construction and function of such a device, and which is hereby incorporated by reference into the present patent application. [0003] A common problem with this type of equipment is cooling down the tool chuck that has been heated for clamping or unclamping. On the one hand, because the time required for cooling tends to increase the overall time required for a tool change before an operable tool is provided again, and on the other hand, because manually dismantling a still hot holding tool chuck will have Substantial accident hazard. [0004] Therefore, cooling with a solid cooling b...
