Latest Patents

One of Nakao's latest patents is a punch unit designed for punching holes in soft metal sheets. This punch unit features a punch that is reciprocally driven during the punching operation, working in conjunction with a die to create precise holes in the workpiece. The design includes punch guides and a die that are integrally formed into a punch block. A critical aspect of this invention is the radial clearance set between the punch and the die, which ranges from 4 to 15% of the thickness of the soft metal sheet being processed. Additionally, the punch unit is equipped with a sheet hold-down mechanism that secures the soft metal sheet during the punching process.

Another innovative aspect of Nakao's punch unit is the inclusion of a cleaning mechanism. This feature scrapes off any fragments of the soft metal sheet that may stick to the punch during operation. The cleaning means operates by reciprocally moving the punch, ensuring that fragments do not remain attached and interfere with subsequent punching operations. Furthermore, the punch drive and control circuit allows for lost motion at predetermined intervals, enhancing the efficiency of the cleaning process.
