RIVCLINCH®

METAL JOINING WITHOUT FASTENERS

WHAT IS CLINCHING?

Upon clinching, double- or multi-layer joints of sheets and/or profiles are joined form-fittingly and non-positively in a push-button-like cold-forming process. With the RIVCLINCH® joining technology, apart from steel and stainless steel materials, also aluminum and other

non-ferrous materials can be joined efficiently and environment-friendly. Furthermore, coated as well as pre-coated sheets can be joined without any damage to the surface. Depending on the chosen RIVCLINCH® joining tools, round or rectangular joint points result.

 

THE JOINING TECHNOLOGY

The first step of RIVCLINCH® joining is to draw the materials to be joined through the punch into the die. As soon as the bottom material touches the die anvil, it starts flowing to the sides and forms a button. After that, the punch moves back into the initial position and the joined part can be removed. A form-fitting and non-positive joint results from local forming.

The advantages at a glance:

     ■  Form-fitting and non-positive joining of sheets and profiles in cold-forming

           ■   No additional fasteners

           ■   Low power consumption

           ■   No thermal load on the joining zone

           ■   No surface damage to coated workpieces

           ■   Films or adhesive as intermediate layer possible in most cases

           ■   No pre-working or reworking required

           ■   Very good reproducibility of the joint

           ■   Environment-friendly at the workplace since there is no gas or noise emission

           ■   Minimum maintenance costs

           ■   Non-destructive testing of the joint possible

THE HAND TOOLS

Our comprehensive RIVCLINCH® hand tool program provides you as the user with the possibility to use clinching technology in your business without high investment costs. The program structure allows to find the right solution for almost every application.

 

THE TOOL KITS

The central component of the RIVCLINCH® joining system is the tool kit.

It is individually adapted to every application. Böllhoff provides different

possibilities of integration into a clinch unit, presses or multistage tools.

 

 

MODULAR SYSTEMS

With the “Modular systems” product series, we have set up a standard clinching program from which we can combine individual clinching tools according to your desired application from different modular systems.

 

 

JOINT POINT GEOMETRY

 

Round point

For round points, the workpieces to be joined are formed locally.

A form-fitting and non-positive joint results which is also visually appealing.

 

Rectangular point

The rectangular point results from a combined cutting and forming process.

It is particularly suitable for hard materials as well as for stainless steel.

 

 

 

Join-able materials

With the RIVCLINCH® joining technology, apart from steel and stainless steel materials, also aluminum and other

non-ferrous materials as well as hybrid joints with foil or adhesive intermediate layers can be joined. Furthermore,

coated as well as pre-coated sheets can be joined without any damage to the surface.

THE DESIGN OF THE SEGMENTED DIE BODY

 

The RIVCLINCH® die comprises a basic die body and individual die ring segments, which are held in position by a steel spring. A safety cage secures the separate sections permanently to the die body preventing them from falling out.

 

The die ring can be divided into 2, 3 or 4 segments with die designs being selected according to the application requirements.
