Riveting Hammer

a hand-held percussion machine used to drive rivets. They are small, weighing 1.5 to 4 kg, and facilitate riveting in poorly accessible spots of structural frames, inside articles being assembled, and in assembly jigs. Compressed air is used to drive a piston enclosed in the housing of a riveting hammer. The piston delivers strokes to a riveting die placed on the rivet. In actual operation the hammer is held by a riveter. A helper holds a riveting dolly, which is placed on the head of the rivet. The quality of the joint depends to a great extent on the operator’s skill. Riveting hammers are currently being replaced by heavier riveting machines in order to achieve better working conditions and to improve the quality of output.
