The FUL number of spring coiling devices from WAFIOS meets the highest standards. In combination having a higher diploma of consumer-friendliness, the machines are intended with utmost productivity and high-quality in your mind. The versions that close in the “6”, which involve the new FUL 166, depict the most up-to-date stage of progress and have chopping-edge mechanical techniques and Manage technologies. There were Formerly 7 types out there, covering spring wires ranging from 0.twelve to 8 mm: FUL 16 to FUL 86 (see Fig. 1). Together with the current addition of the FUL 166 for wires from six.one to 16 mm, WAFIOS is significantly growing the upper conclude on the variety. The features are largely just like Those people of the more compact sister types.
Wire is transported through feed rollers with pneumatic clamping for all equipment – the FUL 16 is the only design exactly where the operator carries out clamping manually employing spring assemblies. The larger sized the equipment or the wire diameter, the more feed rollers are employed (FUL 16 to FUL 46: 2 pairs, FUL 56 to FUL 86: four pairs). The pneumatic Call strain can be altered within the display for each pair of rollers. This concept makes it achievable to accomplish feed speeds of approximately 220 m/min. The lack of hydraulic methods right here offers a significant benefit: Pneumatic elements involve significantly considerably less maintenance. Because of this, the chopping and coiling device has also been made with no use of hydraulics.The FUL 166 is the 1st WAFIOS spring coiling device with six pairs of feed rollers. The complete complement is, however, only expected for wires using a thickness greater than fourteen mm. For thinner wires, the device fitter equips the machine with fewer rollers as is suitable. “There are two possibilities in terms of the amount and structure of the feed rollers are involved,” clarifies Andreas Sigg from the design Office at WAFIOS. “Possibly less pairs with a big diameter, or more using a smaller sized diameter. Significant rollers are significant. So as to make managing as straightforward as you can, we decided on 6 pairs of rollers which were lesser in diameter.”
In combination with the new FUL 166, other WAFIOS products accessible for the manufacture of suspension springs tend to be the FUL one hundred seventy five product (around seventeen mm), FUL 183 (approximately eighteen mm), and – as the most important suspension spring device thus far for up to twenty mm oil hardened and tempered wire – the FUL 203.The feed rollers are fastened for their shaft in two ways: by using positive locking with a few driving pins and via force locking with a preloaded central nut. While in the function of dress in or In case the spring wire thickness is changed, it is incredibly simple to carry out the mandatory modifications.Preserving the (dis)assembly operate to the bare minimum is often a layout theory that runs from the total device. This also relates to the slip Manage, such as, which only ought to be moved out from the get the job done place in lieu of being dismantled. The essential thought is clear: limit changeover time to maximize equipment availability.The machine safety strategy is completely in keeping with this theory, at the same time giving large accessibility and the very best safety for operators. The protective hood opens electropneumatically. The reduced protecting go over can be used in a few positions: about the considerably left for usage of the coiling and cutting unit, to the far proper for use of the feed rollers and chopping device, As well as in the middle for generation operation.
The FUL 166 is a real powerhouse – it must be, with wire thicknesses of as much as 16 mm. The infeed power may be improved to this kind of an extent that even the smallest of spring indexes might be recognized. When extreme forces are concerned, security is an complete must. The entire modular device assembly comprehensive with infeed and coiling body is therefore connected to The bottom. A crossbeam also serves to increase rigidity. Furthermore, The form and slicing slides are intended in a particularly sturdy method. The mandrel box now functions exchangeable dress in plates, which appreciably enhances the service automatic spring coilling machine daily life.The FUL x6 devices give 8 CNC axes as common, covering equally The fundamental features and options to go well with buyer needs: infeed, Reduce, vertical pitch, parallel pitch, height adjustment of mandrel slides, mandrel displacement, and condition/coiling unit (2 axes). Supplemental axes could be put in on most types, one example is a 4-axis coiling device (two axes), a spring leg unit, or maybe a 3D former for difficult torsion springs, or alternatively a PTP coiling finger (two axes) for different the spring pitch. The FUL 166, however, will not be meant for torsion springs; this option is only obtainable for the smaller types.
To be able to Reduce the wire to measurement, the FUL 166 offers the straight cut and the extra torsion Lower variant. This continues to be probable If your spring index is tight (wm<4) (suggest spring diameter/wire diameter), nevertheless it does require a CrSi spring metal with a certain brittleness. With the extra scoring capabilities – a WAFIOS patent – torsion chopping is feasible Despite a value of wm>4. The scoring process utilizes a carbide-tipped, CNC-controlled mandrel. Torsion cuts leave powering burr-free, Practically flat cuts which can be perpendicular towards the wire axis, that’s an advantage for many programs.The equipment also satisfy higher standards when it comes to top quality Handle. This job is entrusted to your WAFIOS Vision Technique (WVS). The springs developed are measured with regard to duration and diameter using a camera and backlight through creation Procedure and the process is regulated. Th
