DESIGN AND DEVELOPMENT OF HYDRAULIC POWER HAMMER

Blacksmithing processes is one of the most ancient craft and forerunner of all metal forming processes used in almost fading out in Nigeria because of the quality and the quantity of the products[3].This paper presents the result of work carried out in improving the design, construction and testing of hammer mill by addressing some lapses associated with the design and construction of the existing ones. These improvement involves redesigning and construction of the hammer mill beater, hammer mill chamber, redesigning and construction of the hammer mill shaft, incorporating a piston cylinder directly to the hammer therebyproviding the means of varying the speed of the hammer [5].The developed cam operated flywheel driven blacksmith forge hammer is used in rural areas. The energy is stored in the form of flywheel. This paper present the design of flywheel and modification of semicircular cam, used for machine which make convenient for rural areas[2].
