Abstract
Aiming at forging machines for bolts and nuts with up to 61% market share, adding piezoelectric sensing units to the mold forging is discussed in this study. In the research process, it attempts to develop a sensing element with low cost, practicable limited space, acceptable performance stability, and real-time measurement of forging load by a five-stage forming system for special nuts matched with the theory of plastic forming, the CAD/CAE design and numerical analysis, and the installation of a piezoelectric unit. It aims to assist fastener businesses in the intelligentization, networking, and systemization of machines and further integrate into the Internet service manufacturing system to enhance the overall competitiveness of fastener industry.
Highlights
Intelligent manufacturing is the inevitable product of mechanized, automated, and informatized application to the mature stage
Intelligent manufacturing refers to the establishment of digitized factories and intelligentized factories/manufacturers, through various intelligent manufacturing systems and automated or intelligentized production lines, to present multiple sensing devices for avoiding possible risks and reaching zero worry for enterprises [1,2]
Fastener industry in Taiwan still exists in following technology gaps [1], when developing intelligent equipment
Summary
Intelligent manufacturing is the inevitable product of mechanized, automated, and informatized application to the mature stage. (1) Sensing technology for molds, principal production equipment (e.g. forming machines, rolling machines), and sieve sorters has not been developed to real-time monitor the quality of fasteners in the process. There have been several researchers proposing various studies on fastener forging forming to solve the practical problems on sites, the introduction of sensing technology to the promotion of intelligent manufacturing, attempting to proceed real-time monitoring and diagnosis technology on fastener molds and principal production equipment (e.g. forming machines, rolling machines) matched with sensing units, is still at the beginning stage. The theory of plastic forming is matched with the CAD/CAE design and numerical analysis to design and develop a piezoelectric measurement unit, expecting to real-time measure the forging load to assist fastener businesses in promoting intelligentized manufacturing and to further enhance the overall competitiveness of the industry
