PLASTIC DEFORMATION OF PROFILED STRUCTURAL ELEMENT MADE FROM COMPOSITE PLASTIC SEMI-FINISHED PRODUCT Russian patent published in 2017 - IPC B29C70/44 

FIELD: construction.

SUBSTANCE: plastic deformation device for manufacturing a profiled structural element comprises the laying device, the clamping device, and the pressure-transferring device. Wherein the laying device comprises the support surface for placing the preform to be moulded thereon. The clamping device is provided for pressing the preform to be moulded against the support surface. The pressure-transferring device on the side facing the preform comprises the non-rigid shell for abutting against the preform in the undeformed first state and for abutting in the deformed second state, as well as pressure-transferring and deformable filler. Wherein the non-rigid shell is made with the possibility to hold the volume covered by the pressure-transferring device. The pressure-transferring device is made with the possibility to be arranged between the clamping device and the preform to be moulded. The clamping device comprises the non-rigid surface which is adjacent to the pressure-transferring device, and wherein the non-rigid surface transfers the force for plastic deformation to the pressure-transferring device.

EFFECT: simplification of manufacturing a profiled structural element with the improved quality of structural elements.
