Project objectives
One of the stages of the pulley manufacturing process carried out by the company Gosan, consists of the union by welding the pulley throat, which is subsequently machined. The welding stage, which is done manually, causes the sizzle of material and sometimes part of that material is deposited inside the soul.
Esta viruta metálica de pequeñas dimensiones, provoca que, en la puesta en marcha en cliente, y durante el inicio del movimiento de la polea, ese material desprendido golpee contra el alma. El ruido que provoca se confunde con el ruido característico de un rodamiento en mal estado y la consecuencia es el rechazo de la unidad fabricada, disminuyendo la eficiencia de la producción.
La empresa no sabe cómo detectar el ruido provocado por dichas virutas por lo que Somorrostro colabora con dicha empresa.
Tasks performed
- Perform a technological check with the aim of being able to detect the manufacturing defect during the manufacturing process. For this, several technological alternatives are presented to be able to detect the chip inside the soul.
- Present different alternatives to the company:
- Ultrasonic technologies, which are used in existing failures in rolling equipment that rotate at speeds below 300 rpm.
- Vibration technologies, which are used in existing faults in rolling equipment that rotate at speeds above 300 rpm.
- Audio analysis technologies based on acoustic pattern recognition
- Advise on the choice of the best technology with the vision of ad-hoc subsequent development to automate the early detection of such anomaly during the manufacturing process prior to mechanization.
