Highly efficient fastening technology for complex and highly precise connections
Short delivery times
ALFING crack and assembly modules were specifically developed for the cracking and assembly of connecting rods in smaller and medium quantities. The hand-loaded modules allow for all process sequences through their modular structure. The same technologies and equipment are used within the modules as with the fully automatic ALFING rotary transfer machines.
The pre-requisite for a precise fracture is the quality of the previously made fracture notch. Predominantly lasers are used to create this notch.
The newest generation of fiber lasers are used in ALFING machines.
The cracking mandrel is the component that decides the quality of every fracture machine. If there is a lack of experience, a lot of bad things may happen here. The result could be unclean breaks, break outs, strong deformation or partial breaks.
This cannot happen with cracking mandrels from ALFING. Due to our decades of experience and our high-speed crack equipment, we have the perfect solution for every connecting rod size and every material. Process monitoring that informs the user of the quality of the crack process at any time is also available if desired.
The bolts are inserted manually or optionally automatically and are pre-tightened. In the next step, the bolts are slightly loosened again and a vibrating unit can be activated to remove any loose particles from the joint faces. The final step is the tightening of the bolts with a defined torque.
The bushes are inserted automatically and - if necessary - aligned before insertion. The bushes are inserted with a servo pressing spindle with simultaneous monitoring of the insertion force and insertion depth.
The bush may also be calibrated.
Connecting rods are highly stressed components and subject to permanent technical development.
With our modernly equipped testing area, we support our customers during different phases of development:
