A process for producing a rope-like spring element semi-finished product, of a spiral spring element, a tool for machining of a rope-like spring element semi-finished product, a shaping body for forming a rope-like spring element semi-finished product and a spiral spring element

摘要

The invention relates to a method for producing a rope-like spring element semi-finished product (10), in which a spring - core body (20) and a the spring - core body (20) surrounding the reinforcement fiber - covering (30), the at least one fiber - filament (32), is made available. At least the reinforcement fiber - covering (30), with a liquid or pasty, hardenable matrix material (78) and, as a result, a preliminary mutual arrangement of the spring - core body (20) and the reinforcement fiber - covering (30) is fixed, and a predetermined cross-sectional shape of the spring element (10) of the semi-finished product formed. A process for the production of a spiral spring element (200) by means of a spring element semi-finished product (10) comprises the steps of the winding of the impregnated and / or at least partially cured spring element semi-finished product (10) by a shaping body (100) with a surface, which on the final geometric shape of the spring element (200) is adapted and / or this and the complete curing (118) of the liquid or pasty, hardenable matrix material (78), as a result of which the spiral spring element (200) is formed. Furthermore, the invention relates to a tool (40) for processing a rope-like spring element semi-finished product (10) and a shaping body (100) for shaping a rope-like spring element semi-finished product (10) in a spiral spring element semi-finished product. Finally, the invention relates to a spiral spring element ..
