초록

An impact member for driven flywheel impact devices, such as nailers and staplers, is disclosed which may be configured to tailor the normal force as a function of ram position. A basic configuration is a constant taper, which, as soon as the impact member is actuated by a flywheel, assists in maintaining driving friction on the impact member. The taper may be linear, stepped or curved, and symmetric or asymmetric about the longitudinal axis of the ram, whereby to tailor the impact member speed for different purposes.

대표
청구항

An impact device having an impact member driven by means of a driven flywheel, wherein the improvement comprises an impact member whose thickness varies over its entire working length, thus varying the normal force of the flywheel against the impact member as a function of the position of the impact member in its working stroke.
