Embodiment Construction

[0024] FIGS. 1 to 4 show a cylindrical housing 1 in the form of an open shell on one side, which is provided with a flat leveling 2 on one side, which is parallel to the central axis 3 of the housing 1. extend. Here, the central chamber 4 of the housing 1 is closed on the open side by a cover plate consisting of a cover ring 5 with a flattened part aligned laterally with the flattened part 2 and a screw. The cover disk 6 is screwed into the thread 7 of the cover ring 5 and is provided with a laterally parallel engagement surface 8 for a tool for the assembly process. Countersunk screws 9 fix the cover ring 5 on the housing 1 .

[0025] As shown in FIG. 3 , the leveling part 2 is provided with connections for the medium to be sprayed in the area of ​​the housing 1 and, for example, a connection 10 for a cooling liquid, a connection 11 for a liquid lubricating medium and a Connection 12 for compressed air. As shown in dotted lines in Figures 1 and 2, a flange 13 can be mounte...

Abstract

Disclosed is a device which can constitute the spraying tip used for lubricating and cooling the mould in the modeling technique, especially for the die and the tool, wherein a transfer passage for cooling the medium, compressing the air and lubricating the medium, is disposed in a common and compact case (1), but are spread dividually, and the divided flow path is provided with a nozzle (20,17), especially used in the spraying for lubricating the medium and the spraying for cooling the medium. The spraying process is best provided by the measure, and makes the consumption of the lubricating medium and the cooling medium keep small.

Description

technical field [0001] The invention relates to a device for lubricating and cooling dies, in particular forging dies and tools, in forming technology, which device has flow channels for conveying lubricating medium and cooling medium, and a device for spraying lubricating medium and cooling medium of the nozzle. Background technique [0002] It is known that in order to accurately shape die forgings, and to release these die forgings from the die, and to reduce tool wear, it is necessary to lubricate the cavity of the die and cool it to The working temperature of the forging die is kept within a limited temperature range. (EP-PS 0 724 486) discloses a plate spray head which can be adapted by the combination of the profile of the forging die shape and has in a plate facing the die cavity a Composition of the mixture through the hole. Such spray heads are relatively complex and have the disadvantage that the lubricant-water mixture cannot be sprayed optimally, so that the ...
