Abstract
A solenoid actuated blind rivet tool having pulling impulse intensifying apparatus co-acting with the mandrel pulling mechanism. One type of impulse intensifying mechanism is a slidable connection of the tool's nose housing, housing the assembly for engaging and tensioning the mandrel, and power chamber which comprises the remainder of the tool housing, which power chamber carries a solenoid for powering the tool. The solenoid pulls the nose housing rearwardly until it impacts against the power chamber, creating a high-magnitude impulse force to break the mandrel. In lieu of a slidably mounted nose piece, the tool may include a member linked to the pulling mechanism and a ram which is driven against the member by the solenoid thereby creating an impulse force which is transmitted to the pulling mechanism.
