Experimental design and fabrication of a portable hydraulic pipe bending machine

Hydraulic operated equipments are used in various fields. Some of them include lowering and raising of chair hydraulically in Barber or Dentist shops, In an Automobile hydraulic jack is raised for grease job. Stepping on the brake pedal creates the hydraulic power, which stops the rotation of the four wheelers or two wheelers to stop. In order to bend pipes, rods and bars hydraulic bending machine is the most suitable equipment. The pipe or rod to be bent is supported between the holders and jack is actuated on pipe. It exerts force on the pipe and bends it to the suitable angle depending on the dies used. Actuation of hydraulic jack is simple and easy to maintain. In industries, they use presses and load appliers to bending applications. These are bulky and expensive. Hydraulic bending machine is portable, flexible and less expensive than those which are discussed earlier. Hence it is better to replace conventional machines by hydraulic pipe bending machine. It helps in reducing size, space occupied, cost employed can be minimized. Manually operated bending machine requires no maintenance and power consumption. During mass production it can be converted into automated or electrically operated jack so that the rate of production can be increased. Applications of bending machines are found to be in production industries, petroleum, chemical, automobile etc.
