Clinching - Import export

TriPress® is a triangular rapid fastening system that can be clinched into plastic and light metals. During the clinching operation, the two components of the TriPress® fastener connect together quickly and economically. It is available in the following designs: Triangular shank and knurl parallel with axis provide greater torsional strength. Circumferential locking flutes on triangular shaft generate high pull-out resistance. Combination of grooves and knurls permit positive-fit fastenings and achieve high torsional torques and pull-out forces (figure 4). So the fastener can be clinched into pre-prepared holes or injected as inserts into plastic housings.

How the fastener functions The material is peeled and a collar formed so that a flush and positive fit of the fastener is created with the sheet metal material. This can either transfer very high forces (e.g. AX 20x14) or with the version that is flush with the sheet, the fastener can be used to directly mount connected parts (e.g. AX 16x4). This principle can be applied to almost every material. The benefits of the RIVORM® HR clinch nut one nut for all sheet metals up to 4.5 mm cost-saving due to fewer variants high-strength, press-hardened and hot-stamped steels very good torsional strength regardless of metal strength high pull-out force The benefits of the RIVORM® TR rivet for fitting ties and springs fully automated processing possible in the subsequent composite tool can be applied universally for different assembly jobs, such as fastening electrical control units, or other plastic parts, simply by clipping them in

With PIAS® pierce-clinch nuts (square) and RIVTEX® (ROUND) a non-detachable metal fastening can be created at optimum cost. The pierce-clinching technology is suitable for steel and aluminium sheets, causes very little cost for inspection and control, and allows several pierce-clinch screws to be processed in a single stroke. PIAS® and RIVTEX® pierce-clinch nuts offer the following advantages over welded nuts: corrosion-resistant no weld spatter on the thread no thermal weakening at the fastening position self-piercing higher torque requirements high process reliability in fully-automated processing flush-mounted processing processing can be manual, semi or fully automated self-locking thread possible

A non-detachable fastening for sheet metals can be produced at optimum cost by using self-clinching screws under the brand names of RIVTEX® (for sheet thicknesses between 0.75 and 2.00 mm) and STRUX® (for sheet thicknesses between 2.0 and 5.00 mm). The clinching technology is suitable for steel and aluminium sheets, causes very little cost in inspection and control, and allows several clinch screws to be processed in a single stroke.
