METHOD FOR THE PRODUCTION OF A ROPE-TYPE SEMIFINISHED SPRING ELEMENT AND A HELICAL SPRING ELEMENT, TOOL FOR MACHINING A ROPE-TYPE SEMIFINISHED SPRING ELEMENT, SHAPING MEMBER FOR SHAPING A ROPE-TYPE SEMIFINISHED SPRING ELEMENT, AND HELICAL SPRING ELEM

摘要

The invention relates to a method for producing a rope-type semifinished spring element (10). In said method, a spring core member (20) and a reinforcing fiber cover (30) which surrounds the spring core member (20) and has at least one fiber filament (32) are provided. At least the reinforcing fiber cover (30) is impregnated with a liquid or pasty, curable matrix material (78), whereby a temporary mutual arrangement of the spring core member (20) and the reinforcing fiber cover (30) is defined and a predetermined cross-sectional shape of the semifinished spring element (10) is formed. A method for producing a helical spring element (200) by means of a semifinished spring element (10) encompasses the following steps: the impregnated and/or at least partially cured semifinished spring element (10) is wound around a shaping member (100) having a surface that is adjusted to and/or reproduces the final geometrical shape of the spring element (200); and the liquid or pasty, curable matrix material (78) is completely cured (118) such that the helical spring element (200) is formed. The invention further relates to a tool (40) for machining a rope-type semifinished spring element (10) and a shaping member (100) for shaping a rope-type semifinished spring element (10) into a helical semifinished spring element. The invention finally relates to a helical spring element (200) comprising a hollow, tube-type fiber composite spring element member as well as a method and a device for producing a helical spring element (200).
