I Built a Hydraulic Tube Bender, and It Works

I had been planning to build a tube bender for a long time, and I finally decided to make it happen! The project required a lot of work, especially when making the bending dies (which are sometimes called "stones" in my country) and guides. I managed to create four sets for tube diameters: 22 mm, 25 mm, 28 mm, and 32 mm. I wanted the machine to have its own hydraulic power supply, so I installed a 1.1 kW (1400 RPM) motor connected to a 6 l/min (4 cm³) hydraulic pump. The system operates at a maximum pressure of 140 bar, which is enough to efficiently power the hydraulic cylinder (28 mm rod, 350 mm stroke). The bender easily handles 32 mm tubes with thick walls, which encouraged me to design even larger bending dies and guides for bigger tubes. As for the angle gauge, I simply used a regular school protractor – and it turned out to be surprisingly accurate!
