New insertion system for blind rivet nuts SBM25 – with four-fold benefits

Press information 04-2022 dated 11/07/2022

WEBER has thoroughly revised its successful model and is now offering an insertion system that is impressive due to its speed and flexibility | SBM25 celebrates its world premiere at the “automatica Munich” in June, and is a testament to the company’s expertise and experience

Wolfratshausen – WEBER Schraubautomaten GmbH presents the SBM25, the second generation of its completely revised insertion system for blind rivet nuts and studs, at the “automatica” international trade fair in Munich.

“The new SBM25 is our solution-based response to the customer requests we have received in recent years. We have invested our 20 years of intensive experience in this product area into the system,” explained Michael Steidl, Product Manager at WEBER.

Blind rivet nuts offer the user multiple benefits and are an indispensable component of modern fastening technology. With the innovative SBM25 insertion system, WEBER has created many more options for the fully automatic processing of blind rivet nuts and studs for a wide range of applications.

In line with customer requirements, the SBM25 has been further developed in terms of system flexibility. A wide range of commercially available blind rivet nuts and studs can now be processed. One of the stand-out features of the SBM25 is an alignment and clamping unit for all nut types. Multiple systems can be run with just one controller/feeder to achieve the greatest possible flexibility. Finally, a complete bus connection for the individual components has been achieved, making configuration of the SBM25 significantly easier and faster.

Transparent, time- and cost-efficient

With its new insertion system, WEBER is also redefining the speed of such systems: rivets and other fasteners are now fed via a push-in system, which reduces feed times. As with the previous model, threading and insertion of the components is carried out via two separate EC drives. The setting process can be freely configured via the operating panel. The device works according to the ‘spin-pull’ principle, so that symmetrical deformation of the shank and surface-friendly processing are guaranteed. The setting process takes place without hydraulic support.

Steidl: “WEBER’s competence and many years of experience with these insertion systems is consistently demonstrated in the SBM25. One of the results of this development work is the alignment and clamping unit for the fasteners, which is for all nut types, thus enabling us to set standards.”

Customers ordering the SBM25 will be able to seamlessly monitor the setting path and insertion force for the joint. In terms of process reliability, the system offers the added benefit of being able to visualise multiple displacement/force curves, significantly improving ease of use and error analysis. WEBER offers a global service for its systems consisting of 40 service specialists – spread over all continents and in the key sales markets.

When inserting blind rivet nuts, work is often carried out with exceptionally thin components, which are only accessible from one side or are already coated. This requires continuous monitoring of the work process. In this way, malfunctions can be ruled out. With the new SBM25, both the applied force and the feed rate are controlled. This ensures maximum process reliability, even in large-scale production.

The SBM25 can be used in all working directions – even where access is on one side. Hexagon and round nuts in the sizes M5, M6, M8, M10 are processed as standard. Customised solutions for other shapes and sizes are available on request. WEBER’s SBM25 insertion system for blind rivet nuts can be used separately as a work spindle at individual stations or as a robot spindle. The fasteners are fed via a hose.
