This paper discusses about design and characteristics of hydraulic sheet metal benders. Today, there are many different versions of hydraulic presses for bending sheet metal, which work with larger material thicknesses and smaller ones. Most hydraulic sheet metal bending presses work on the same or similar principle with different designs, and the paper describes in detail the construction design with all parts and characteristics of the machine, mode of operation and assembly. The processing of the material by means of hydraulic bending presses takes place without separating the sawdust under pressure loading. Hydraulic benders are the strongest bending machines and have much higher pressures and power than mechanical presses. The paper describes the divisions of the performance of hydraulic presses for circular bending, angular bending and profile bending, which depend on the purpose of the material. The machine is operated manually or using a program that can be corrected at any time. Manual-driven machines are mostly used in single production for simple constructions up to a certain sheet thickness, while program-driven machines are used in more complex workpieces where high accuracy of bending angle is required. The hydraulic control scheme of the machine are shown with all parts and calculation of hydraulic press of given dimensions.
