Rancang Bangun Alat Roll Bending Pipa 1/2 Inch Semi Otomatis Menggunakan Penggerak Motor Listrik 1 Phase

This study discusses the design and development of a semi-automatic pipe roll bending machine for ½ inch and 1 inch galvanized pipes, driven by a single-phase electric motor. The tool was developed to overcome inefficiencies and inaccuracies commonly found in manual pipe bending processes. The research stages include literature review, mechanical design, component selection, assembly process, and performance testing. Testing was conducted using galvanized pipes with diameters of ½ inch and 1 inch, and lengths of 1500 mm and 2000 mm. The test results showed that the tool was able to bend the pipes into a full circle (360°), with an average processing time of 1230 seconds for a 1500 mm pipe, and longer duration for 2000 mm pipes. These findings indicate that the tool operates effectively and more efficiently compared to manual methods. This machine is expected to be applicable for small to medium industries and serve as a practical implementation of appropriate technology.
