Abstract (en)

[origin: WO2015162490A1] The invention relates to a device and a method for the thermal transforming of hose blanks from preferably pre-extruded elastic raw hose material, wherein during the transformation the hose blank is arranged in a shell-like, single- or multi-piece moulding tool with a hollow body, wherein the inside of the hollow body corresponds as a negative to the shape to be impressed in the hose blank, wherein the required temperature control of the moulding tool for transformation is performed by jaw-type temperature control elements which close interlockingly over the tool and which are shaped congruently to the outer surface of the tool, while the moulding tool itself does not have any temperature control device, in particular no channels or other cavities for circulating a temperature control medium, and whereby the temperature of each temperature control element is kept constant during the course of the process, while another temperature control element with a corresponding constant temperature is moved up to the moulding tool to change the temperature of the moulding tool. With the device according to the invention, the moulding tool is free from inner channels and other cavities for the circulating of a temperature control medium; while for temperature control, the moulding tool temperature control elements separated therefrom are provided with semi- or part shells which close interlockingly over the tool, the insides of said temperature control elements, which insides face the moulding tool, are formed congruently to the outside of the moulding tool, and the temperature control elements comprise a device in order to keep the temperature of each temperature control element constant during the course of the process, and wherein at least one mechanism is provided so that the various temperature control elements with different temperatures can be selectively closed around the moulding tool.
