TOOL FOR PRESSURE CONFORMATION AND PROCEDURE FOR THE PRODUCTION OF A PART BY PRESSURE CONFORMATION.

摘要

Ethyl forming of pressure for the production of a piece from at least a first layer of material (1) and a second layer of material (2), with at least a first part of tool (11) and a second part of useful (12) presenting in each case a three-dimensional conformal contour, useful in which, when the first layer of material (1) and the second layer of material (2) are introduced into the device, the contour of the first tool part (11) looks towards the first layer of material and the forming contour of the second part of tool (12) looks towards the second layer of material and in which the tool parts (11, 12) are held in a presser to produce the conformation of the first layer of material (1) and the second layer of material (2) and the union of both layers of material with each other by an approach of the first and the second part of the tool, as well as with a tensioning frame device for, during the pr Forming, holding the layers of material outside the contour area of the tool in its closed position, the pressure forming tool comprising a cutting device (300) with a blade (330) which, seen in the opening direction and closing, it extends along the periphery of the useful parts (11, 12) by segments or completely surrounding it, it is provided to cut a projecting part of the layers of material (1, 2) existing in the pressure forming together with the first and the second part of the tool and can move relative to the first or the second tensioning frame element (22, 23), characterized in that the tensioning frame device has a first tensioning frame element (22), which can be moved by means of a first adjustment device (31) in relation to the first tool part, and a second tensioning frame element (23), which can be moved by a second adjustment device (32) in relation to the second pa useful, the tensioning frame elements (22, 23) being arranged to hold at least two layers of material and at least one spacer frame element (22, 23) being arranged at least one spacer element to separate the tensioning frame elements (22, 23) from each other in their closing position, so that, in the closing position of the tensioning frame elements (22, 23) and during a compression operation realized by means of the tool parts (11, 12), a subsequent flow of at least one of the material layers (1, 2) introduced is allowed.
