Abstract

Electromagnetic actors (solenoids) are used in automotive and automation
technology as valve actors for pneumatics and hydraulics or as
actuating and pressure solenoids. During assembly there are often
press-in and caulking processes used. A central quality aspect of the
final control elements is the adherence to defined actuating force
ranges in order to ensure the switching process and at the same time to
keep wear within limits. These defined force ranges can currently only
be maintained by additional heat treatment of the parts. The hysteresis
of the assembled unit can be influenced by the caulking. The objective
of this paper is to propose the potential reduction of annealing
processes by revealing the interdependencies between the magnetic
interactions of the individual components and the assembly process
parameters. In addition, errors in the caulking process are detected and
prevented at an early stage. A magnetic characterization of the soft
magnetic components and assemblies before and during their assembly is
proposed. Furthermore, the integration of the measurement data into a
process control system is intended. The precondition is the development
and construction of measuring equipment and systems that can be used to
assess the magnetic properties at an early stage of assembly. The
assembly can then be adjusted in order to compensate batch fluctuations.
As a consequence new materials can be used to eliminate complex
annealing processes prior to assembly.
