Optimasi Mesin Kombinasi Pelubang Dan Penekuk Pelat
ABSTRACT
The combination punch and bending machine is a machine that belongs to the press
type with the use of punch and die. This machine has a hydraulic drive with a
maximum pressure generated of 700 bar. While the engine performance is only able
to withstand a working pressure of 27.7 bar, therefore the utilization of the working
pressure that is owned needs to be increased so that the available working pressure
can be maximized. The analysis was carried out on the machine with two methods,
this is simulation and experiment. The simulation method is carried out using
Autodesk Inventor software to design and simulate in order to make it easier to find
out the critical points that occur on the machine when it is given working pressure
according to the permitted safety factor 1,5 The experimental method is carried out
by measuring the voltage using a Strain gauge sensor positioned at the critical
point obtained in the simulation and measuring the deflection using a dial indicator.
From these tests, it was found that the initial working pressure before being
optimized was 27,7 bar to 49,5 bar after being optimized.
