Protection against electrical surges

Stamped and formed parts as well as assemblies manufactured on Bihler production systems simplify our daily lives and offer safety and security. For instance, circuit breakers. In the event of a short circuit, they guarantee a safe shutdown and protection against overload.

A central component of circuit breakers is the unalterable trip-free mechanism. This assembly ensures immediate triggering in the event of a short circuit, even with the control lever actuated or held in the ON position.

The freely moving component is manufactured on a GRM 80P stamping and forming machine by one of our customers at a rate of 200 parts per minute. This high productivity is also achieved for the remaining components of the circuit breaker, which can be smoothly manufactured using various other Bihler production systems.

Safe mains supply

NEMA sockets are a common type of mains power receptacle used in the United States, Canada and parts of Asia. NEMA receptacles are designed for voltages of 125-600 volts and currents of 15-50 amps. It goes without saying that safe and simple use is the number-one priority. A key part in these receptacles is the connecting piece that carries the mains current to an attached electrical appliance or other load.

In the USA, this connecting piece is made on a GRM 80 mechanical stamping and forming machine and a BZ/2 processing center. Together, they carry out all the necessary steps, from punching and bending to thread cutting, screw insertion and assembly. These two Bihler systems, working in three lines, produce roughly 300 of these receptacle parts. There are around 80 variants of the final product. The Bihler machines, running 24/7, excel in terms of their reliability. They also operate as smart network, which allows them to buffer production – a valuable capability.

Reliable power connections

Terminal clamps like this are made in a Bihler BZ 2/4 processing center. Its modular, open design places almost no constraints on how processing units needed in a manufacturing process can be integrated, making it ideal for the production of high-quality precision parts – parts like battery terminal clamps, which require a range of steps (specifically, punching, bending, stamping, assembly and feeding) to be performed on a single system. The output rate runs to around 150 parts per minute. The BZ 2/4 processing center combines this kind of high processing speed with exceptional precision while minimizing offcut and scrap.
