Perancangan Dan Analisis Kekuatan Konstruksi Mesin Tekuk Plat Hidrolik
Abstract: Manufacturing
business has developed very rapidly this year; not only large companies but
also small companies contribute to developing manufacturing business.
Small-to-medium scale enterprises still use simple instruments compared with
large companies. The example is bending process. The small-to-medium scale
enterprises still use conventionalmethod, such as knocking the material or
clamping it, until the bended material and meet the objective. This process is
not efficient and effective, because of much cost, time, and energyuses, but
the quality of result is not guaranteed. Learning from that problem, the
small-to-medium scale enterprises should reduce the expense using several
affordable bending machines but have good quality to improve their
productivity. This research aimed to get a plate bending machine design with
low cost and high quality so that the small companies could compete with the
large ones. The designed bending machine should pass through calculation, 3D
imaging and be simulated to get a safe bending machine design. The design
process was conducted by obtaining the design concept developed by the
respondents. The calculation of each component comprising it was conducted by
using simulation feature of Solidwork 2012 software. From the design,
calculation, and simulation processes, the strength of every machine component
could be estimated, so that the selection of shape, size, and material of every
component could be decided more effectively. The result of design constituted
bending machine work image in 2 m (length) x 1 m (width) x 2.6 m (height)
dimension. The machine employed a hydraulic mechanic system with two actuator
cylinders having 90 ton capacities and would be used to bend the material with
ultimate strength to 370 N/mm2 with the maximum thickness of 7 mm. From the
result of simulation using Solidwork 2012 software, the design of machine could
restrain the load of bending strength to 882 kN without construction failure.
