A method for producing a helical spring and apparatus for producing a screws spring semifinished product

摘要

The invention relates to a method for producing a helical spring, in particular for a wheel suspension of a vehicle, comprising the steps of:– Providing a pliable, elongated semi-finished product (3) from a fiber composite material;– Providing a tube (4) made of an elastic material;– Movement of the semi-finished product (3) by means of a in the direction of a direction of movement of the semi-finished product (3) tapering funnel (5) and through an opening (10) on a with respect to the direction of movement of the semi-finished product (3) is connected downstream of the funnel (5), at a distance from the funnel (5) arranged guide element (8); and– Coating of the semi-finished product (3) with the hose (4), in that the hose (4) during the movement of the semi-finished product (3) in the same direction to the semifinished product (3) by means of an outer casing surface (7) of the funnel (5) and through the opening (10) is moved, with the movement of the hose (4) and the movement of the semi-finished product (3) are adapted to each other in such a way that, within the opening (10) a speed of movement of the hose (4) of a speed of movement of the semi-finished product (3) corresponds to.
