Optimization of Speed Cylinder and Distance Speed Cylinder Hydraulic Movement of Kobelco Tire Curing Machine

摘要

The process of making tires is using the curing process, this process using the Kobelco curing machine. Press Unit Problem contribute 51.5% of the total problem in curing process. Press unit problems caused by dry time in press cylinder unit to open or close movement still takes long time which is not productive. Improvements made by modifying the speed cylinder and distance speed cylinder movement. Optimization of Speed Cylinder by modifying the setting of speed parameters on the cylinder selenoid valve, while optimizing the distance speed cylinder movement by modifying the PLC program to obtain optimal speed of movement distance. The results obtained after optimization obtained 100 mm/s of hydraulic speed cylinder, and 45° mechanical flow control. The problem of the press unit decreases, while the dry time reduced by 37% so that the production of tires increases 12 pcs tires/day/machine, so that total saving cost as much as IDR. 84,000,000.
