Design And Fabrication Of A Manually Operated Hydraulic Press And Pull Machine

ABSTRACT

A hydraulic press and pull machine comprising of: a frame, cylinder and piston, two threaded studs, hydraulic pump and hose, pulling clamp and a work piece support was designed, fabricated and simulated. The machine is operated manually. The maximum shear force, maximum bending moment and maximum displacement of the machine work piece support were determined as 74.9491N, 16.6335N-m and 4.367e3mm for a simulated load of 580N. Maximum axial stress, bending stress and torsional stress where also determined as 0.00359, 701998 and 0.00653N/m2 respectively using Solid works simulation. The machine which was fabricated with locally sourced standard materials will reduce the time and stress associated with installation and removal of bearings, and other forms of force fits in machine assemblies. 1-Jence, leading to an overall improvement in the standard of machines/equipment fabricated within the country.
