Abstract:
A spring forming apparatus is shown generally at (200), in which metal wire (220) is fed from a supply (not shown) by feed rollers (230), via irregularity-effecting rollers (240) to a forming station (250). The forming station comprises a first deflector (260) and a second deflector (270). When the spring S is complete, it separates automatically from the rest of the wire (220) due to the presence of an irregularity (280), without the need for a cutter device.
Abstract:
An exemplary embodiment provides a method of manufacturing a string of pocketed spring coils comprising: simultaneously making at least two spring coils; simultaneously transporting the at least two spring coils to a compressor: simultaneously compressing the at least two spring coils; simultaneously inserting the at least two compressed spring coils between top and bottom plies of a piece of fabric; welding the top and bottom plies of the fabric along an edge of the folded fabric parallel to the longitudinal axis of the fabric and opposite the folded edge of the fabric; welding the top and bottom plies of the fabric along lines transverse to the longitudinal axis of the fabric between each of the compressed spring coils to create a plurality of pockets, each pocket encompassing a compressed spring coil; and expanding each of the compressed spring coils within each of the plurality of pockets.
Abstract:
The invention relates to a method of manufacturing a coated spring, said method comprising the steps of - providing a steel wire; - coating said steel wire with a silane based coating in the range of 4 to 10 μm to provide a coated steel wire; - subjecting said coated steel wire to a mechanical deformation to obtain a coated and mechanical deformed steel wire; - subjecting said coated and mechanical deformed steel wire to a stress relief treatment. The invention further relates to a coated spring.
Abstract:
A wire coiling device for manufacturing pocketed springs (24) comprises a wire supply station located above or below the coiling device, to take up less footprint in the factory. The wire supply station comprises a container (34) in which the wire is retained in a multitude of pre-straightened loops of substantially the same diameter around a cylindrical inside surface of the drum. The wire (16) emerges from the drum (34) under no tension and substantially straight. It is then fed between guide or feed rollers (20) into the coiling head (12).
Abstract:
Provided are a hollow coil spring and a method for manufacturing the hollow coil spring, whereby inner surface corrosion can be prevented, and product appearance can be improved. In an end sealing step, the core material of an end (Wa) of a spring material (W) is gathered by machining to seal the end (Wa). Spinning is preferably carried out as the form of machining. While pressing the end of the spring material (W) with a squeezing roller (R), for example, toward the inside in the radial direction, the squeezing roller (R) is appropriately moved in the axial direction as necessary. The end (Wa) of the spring material (W) is thus occluded, as shown in figure 3, eliminating the need to use a separate member such as a lid member. Such an end sealing step can be carried out immediately after an inner surface processing step, for example. In a coil forming step performed after the end sealing step, even if the end (Wa) of the spring material (W) is gripped and the spring material (W) is wrapped around a rod, the formation of a gap at the end (Wa) will be prevented.
Abstract:
The present invention relates to a method of manufacturing a spring coil using a helicoid reduction mill, in which a wire shipped from a steel-making plant is further hot-rolled and simultaneously formed into a coil spring within several seconds, and thus the tensile strength of the formed spring coil becomes higher due to an ausforming effect occurring at the time of quenching special steel, and in which an austenite structure can be safely maintained at room temperature and can also be highly densified to obtain a high-stress product, so that the fatigue life of a coil spring can be increased, with the result that the length of a coil spring material can be greatly decreased at the time of manufacturing a coil spring requiring uniform strength, thereby decreasing the weight of a coil spring.
