Abstract

The invention relates to a cooling system for cooling a tool via cooling sites (6), these being composed of a capilla-ry tube (64) associated with a supply pathway and of an expansion space (65) which is associated with a return pathway (41) and into which the capillary tube (64) leads, so that a coolant conducted in liquid form to the cooling sites (6) evaporates and is con-ducted away in the form of gas. A distributor block (1, 11), which can be connected to a coolant source and to a coolant sink, and into which coolant channels (3,31,4,41) have been moulded in at least one plane, has been designed so that it can be flanged onto a tool.

Claims (7)

1. Coolant distribution for the cooling of a tool through cooling points (6) that consists of a capillary tube (64) connected to a feeding loop (31) and an expansion chamber (65) connected to a return loop (41) into which the outlet of the capillary tube (94) opens so that a coolant conveyed in a liquid state to the cooling points (6) evaporates and is drawn off as a gas, characterized by the fact that a hermetically sealed distribution block (1, 11) attachable to a coolant source and a coolant sump is fitted with coolant channels (3, 31, 4, 41) carved out in at least one plane and conformed to be attachable to a tool by a flange, the coolant channels (3, 31, 4, 41) are conformed as feeding loops (3, 31) branching out to the cooling points (6) and as return loops (41) leaving the cooling points (6) to be joined in a collective conduit (4), the coolant feed occurs from the coolant source to the feeding loops (3, 31) through a first hose (321) attached to an inlet conformed as a hose coupling (32) and at least one magnetic switching unit (2) mounted after the inlet, and the coolant discharge occurs from the collective return conduit (4) through a second hose (421) to the coolant sump, where the outlet of the collective return conduit (4) is conformed as a hose coupling (42) to which the second hose (421) is attached.
2. Coolant distribution according to claim 1, characterized by the fact that the coolant channels (3, 31, 4, 41) are boreholes introduced into the distribution block (1), which lead to crossings forming connecting points and/or directly to the cooling points (6), and are hermetically sealed toward the outside.
3. Coolant distribution according to claim 1, characterized by the fact that the distribution block (1, 11) consists of at least two plates and the coolant channels (3, 31, 4, 41) and are conformed in at least one plate (1) as groove-like recesses and covered by another plate (11).
4. Coolant distribution according to claim 1, characterized by the fact that the coolant channels (3, 31, 4, 41) are realized so that grove-like recesses are carved out in the distribution block (1), in which the tubes conveying the coolant are set in an irremovable manner.
5. Coolant distribution according to claims 1, 2, 3 or 4, characterized by the fact that at least one magnetic switching unit (2) is attached to the feeding loop (3, 31) by plug-in connectors (5).
6. Coolant distribution according to claims 1, 2, 3, 4 or 5, characterized by the fact that the capillary tube (64) is fastened to a connecting element (62) with an inlet and an outlet, so that the capillary tube (64) is tightly connected to the feeding loop (31) by the inlet, and the expansion chamber (65) is tightly connected to the return loop (41) by the outlet.
7. Coolant distribution according to claim 6, characterized by the fact that the connecting element (62) is conformed as a supporting bushing (61) set in the distribution block in a plug-in manner.
