Progressive Tool Modernization Using Sensor Technology in Automotive Parts Manufacturing

Abstract

In this research presented an experimental study, which extends usage of eddy current sensors in outdated progressive stamping tool and overall press system in automotive parts manufacture. During the test various tool sections were modified in order to implement sensor’s and keep optimal design principle. Experiments were carried out using 4 mm thickness, cold rolled steel material. The purpose of the research was to automatically detect material scrap before it leaves imprints on part and stop the press in order not to damage stamped part of tool itself. Scrap thickness that needs to be detected was established by experimental way and was 0.1 mm. Research results were consist of separate detection steps and conclusion taken only after serial type production with simulated more severe conditions than actual production. Overall results were influenced by the design of the existing tool; however, scrap detection on any place of strip was achieved and additional scrap detection map was created. Determinate that detection is influenced by tool dimensions, existing design and used sensor’s type.
