Henrob Overview Brochure

  1. 1. Henrob Self-Pierce Riveting Technology (HSPR) Our reputation as the pioneer of modern day self-pierce riveting has been built on providing creative products and joining solutions for our customers throughout the world. We invite you to take advantage of this service.
  2. 2. HSPR Technology How SPR Benefits Your Assembly Self-pierce riveting is a process of joining two or more layers using an engineered rivet. Unlike conventional riveting, HSPR does not require a drilled or punched hole. In terms of product design and ease of integration into your manufacturing process, HSPR is a very flexible system. Ensuring superior, consistent joint performance, HSPR can outperform both conventional riveting and welding. 1. 2.

Benefits of using self-pierce riveting technologies • Can fasten stacks of 2 or more layers; current applications include up to Benefits over welding 12mm total thickness in aluminum and • HSPR can join dissimilar materials 6mm in steel • HSPR installation equipment is operator- and • Will not damage coated or painted environment-friendly: applications – no cooling water or fume extraction is required • Provides repeatable joint strength – no waste products are generated • Eliminates hole preparation – noise levels are low, typically <80dBa • Can replace expensive, multi-piece • Riveted joints can be checked visually for proper fasteners fastening • Provides superior static and dynamic • HSPR is compatible with adhesives and sealants, load-carrying capabilities including layered sheets • Because the bottom layer is not pierced, • HSPR can be used on coated and painted surfaces, an HPSR joint can prevent the ingress of and will create better joints even on steel with liquids or gases through the fastened thicker coatings of zinc joint • Because HSPR is a cold form process, distortion due to heat-affected zones is eliminated
  3. 3. Equipment Henrob‘s philosophy is to design reliable, robust solutions for production. This is achieved with the aid of 3D computer-aided design (CAD) software allowing in-depth modeling of tools and product access studies. Finite Element Analysis (FEA) software is used to ensure adequate life expectancy of tools. Electric servo and hydraulic systems are available. The size, shape and configuration can be engineered to place the fasteners quickly and consistently. A lower-weight frame can be built to accommodate pre-existing equipment. Optional process monitoring equipment ensures proper, consistent placement with manual, pedestal or automated assembly. Many feed systems are available, including tape, mechanical cassettes and loose feed. Robotic placing arms and process monitoring equipment can be integrated as needed. Standard Systems • Rivlite Manual Tool • Single- and double-acting hydraulic tools • Pre-clamp systems Options/purpose-made systems • RivMon process monitor • Hydraulic pre-clamp-based systems • Electric-servo based systems • Mistake-proofing options • C-frames to meet your configuration • Handling accessories
  4. 4. Applications Whether developing a new product or streamlining assembly of an existing one, you can rely on Henrob’s experience and innovation in fastening technology. Henrob fastening systems have benefited applications in a wide variety of industries around the world. From standard tools to customised systems, from rivet joint design assistance to automated assembly cells, Henrob can find your optimal solution. Materials that can be fastened construction with HSPR • steel (including high strength steel) • aluminum • plastics such as nylon • composites • sheets with an intermediate layer of adhesive, insulation, sealants, etc. recreational automotive transportation industrial ductwork white goods agricultural electronics About the company Henrob’s principal activity is designing and manufacturing self-piercing rivets and installation systems, for which the company holdsa a number of patents.
