Products include pressure filters, return linefilters, elements, spin-on filters, suction strainers and filler breathers forvarious hydraulic, lubrication and fuel manufactures more than 10,000 different elements. Many ofthese are designed to fit into filter housings produced by other companieswhile maintaining or surpassing the original STAUFF hydraulic accessories program has been carefully designedto offer a range of components suited to the demands of buildinghydraulic systems in most industrial and mobile you require simple filler breathers or precise electrical levelswitches, flow control valves or complete filter units.

Due to theextraordinary wide product range, all areas of pipe, tube and hoseinstallation are covered:2142155 MbThe main requirements forhydraulic connections can besummarised in three words: Safety, as the most impor-tant aspect. Quality, without which per-manent freedom from leaksis not possible. Profitability, only aneconomical coupling canprevail on the new VOSSFormSQRtubecoupling system fulfils theserequirements with its innova-tive design based on theproven VOSS design contour is formed on at theend of a standard hydraulictube in the VOSSForm100pre-assembly machine.

3 Whena soft seal and the specialSQR nut are added, a simple,high-quality loadability andsafetyThe critical area is the transi-tion from the formed contourto the tube. Here the formingprocess can result in materialembrittlement. With theVOSSFormSQRsystem thisweak point is effectively re-lieved. On the one hand, theradiused transition minimisesthe notch effect. On the otherhand, the SQR nut with the in-tegrated clamping ring clampsin the tube radially on thecircumference, absorbing thedynamic loads before the criti-cal area and increases thepressure loading capacity andresistance to Information VOSSFormSQRTube CouplingsAbsorption of dynamic loads by integrated clamping ringradiusedStandard connecting piece in accordance with DIN 3861 / ISO 8434-1 Formed tube endStandard nut in accordancewith DIN 3870 / ISO 8434-1 Sealing ringClamping ring (pressed into nut)Assembly safety with surestopSafe assemblies mean safeconnections.

4 With the VOSS-FormSQRS ystem the face of thetube end strikes against thebottom of the standard DIN/ISO connecting pieceduring assembly. When thenut is tightened, the end ofassemblybecomes clear froma noticeable increase in and over-tightening canbe virtually eliminated. In addition, the assembly pathis reduced, and with it themounting time. The formed-oncontour is deeply inserted intothe 24 taper, ensuring pre-assemblyForming with the VOSS-Form100 pre-assembly deviceis extremely simple. The simplepushing in of the tube endagainst the stop and the moni-tored forming allows no errorsto occur. The inner mandrel onthe forming head preventsconstriction of the tube in theformed area. The inside tubediameter is completely retained,preventing pressure lossesdue to inward times from 12 to 15seconds particularly decreasethe assembly times in from leaks withsoft sealA soft seal offers considerableadvantages over a purelymetallic seal.

5 Leaks due to thecomponents settling undermechanical loading are com-pensated. This effectivelyprevents connection completely leak-tight con-nection even in the precisionarea is more economical, pro-tects the environment andemphasises the quality of theconnection, and therefore alsoof the entire concept of locating thesoft seal in the secondary area as with the ES-4 cuttingring minimises both staticand dynamic loading of theseal. The metallic primarythrottle on the face of the tubedampens the load duringpressure change loading. With static loading there is amajor time delay in chargingwith pressure. This type ofarrangement ensures the long-term stability of the leaks, minimising theassembly time and eliminatingmaintenance effort and ex-pense is an excellent basis foreconomy. Low material costsand simple parts handling alsomake VOSSFormSQRtube cou-plings an especially advanta-geous solution for series product rangeThe condition for the success-ful use of connection systems isa broad range of products.

The monitoredprocess in conjunction withoptimum tube guidance makesdefective forming as a result ofincorrect operation virtually tool changes consider-ably contribute to reducingprocessing times. The clamp-ing jaws and forming head canbe replaced without tools. The clear marking of bothtools prevents assembly errorsdue to incorrect combinationsof tools and tube forming processForming begins with the tubebeing pushed into the pre-assembly machine against thestop plate.

7 Pressing the Startbutton triggers the process(1.).The clamping jaws close andclamp the tube in place. The stop plate swivels out ofthe forming area (2.).The forming head movesforward and forms the VOSS-FormSQRcontour plastically onthe tube (3.).The forming head moves backand the clamping jaws open(4.).Removal of the tube is moni-tored. As a result, the devicecan automatically move intothe starting position again andbegin the next tube formingprocess without the necessityof manual resetting (5.).Ordering information for thepre-assembly machine and toolsets is available on request. 1.
