A device and a method for the thermal reshaping of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the reshaping, the hose blank is arranged in a shell-like, single- or multi-piece molding tool with a hollow body, wherein the tempering of the molding tool that is necessary for reshaping occurs by means of clamp-like tempering elements which are shaped congruently to the outer surface of the mold and which close form-fittingly over the mold, while the molding tool itself does not comprise any tempering system at all, in particular no ducts or other hollow spaces for circulating a tempering medium, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a correspondingly constant temperature is positioned against the molding tool.
Method for the thermal reshaping of hose blanks consisting of elastic raw hose material, wherein the hose blank is located in a hollow, single- or multi-part molding tool during the reshaping, wherein the inner side of the hollow mold corresponds as a negative to the shape that is to be impressed upon the hose blank, characterized in that the tempering of the molding tool that is necessary for reshaping occurs by means of tempering elements with half or partial shells which close form-fittingly over the mold, and the inner sides of said shells that face the molding tool are congruent with the outer side of said molding tool, wherein no tempering device, no ducts or other hollow spaces for circulating a tempering medium at all are integrated into the molding tool itself, and wherein the temperature of each tempering element is kept constant during the process, while, to modify the temperature of the molding tool, a different tempering element with a different constant temperature is positioned against the molding tool.
Device for the thermal reshaping of hose blanks consisting of elastic raw hose material, comprising a hollow, single- or multi-part molding tool with a hollow mold for receiving at least one hose blank while it is being reshaped, wherein the inner side of the hollow mold corresponds as a negative to the shape that is to be impressed upon the hose blank, characterized in that the molding tool is free of internal ducts and other hollow spaces for the circulation of a tempering medium, while half or partial shells, which are separate from the mold and which close form-fittingly over the mold, are provided to temper the molding tool, wherein the inner sides of said shells which face the molding tool are congruent with the outer side of said molding tool and wherein the shells comprise an arrangement for keeping the temperature of each tempering element constant during the process, and wherein at least one mechanism is provided for selectively closing different tempering elements at different temperatures around the molding tool.
