Abstract

PURPOSE: To improve operation of a solenoid type plunger hammer, by making its hammer shafts with austenitic stainless steel and and its bearings with polyimide resin, and thereby minimizing wear of the hammer shafts and bearings.
CONSTITUTION: Hammer shafts 6A, 6B are extended on the opposite sides of plunger 5 which is disposed in a hollow space in exciting coil 2 in axially movable manner. Shaft 6A is loosely fitted in front bearing 7A disposed on the inside of outer sleeve 4, and shaft 6B is loosely fitted in rear bearing 7B disposed on the inside of yoke 3. The unitary body of shaft 6A, plunger 5 and shaft 6B is thus supported in axially movable manner between bearing 7A and bearing 7B. In the above arrangement, hammer shafts 6A, 6B are made of austenitic stainless steel and bearings 7A, 7B are made of polyimide resin, whereby it is enabled to mininize wear of shafts 6A, 6B and bearings 7A, 7B and thus to operate the hammer shafts as a high speed.
