Lightweight Handheld EMR with Spring-Damper Handle 2000-01-3013

Early versions of handheld (HH) electromagnetic riveters (EMR), while effective, were heavy. With the proven effectiveness of the EMR, the next step was to make the HH riveting system light and portable. To maintain the required output force in a small package, the upper limit of the voltage range was increased to 1000V, twice that of conventional 500V LVER systems. The 0-1000V range of the HH50s allows for the formation of rivets up to 3/16″ diameter. Due to the lower mass in the HH50s, the riveting actuator was developed to strategically maximize output force and minimize recoil. Recent developments have been made to drastically reduce recoil by incorporating a spring-damper system integral to the HH50 handle.
