Fabrication of a Pneumatic Pipe & Rod Bending Mach

Abstract

Rod and pipe bending is widely used for various industrial purposes. Most of the rod bending machines are hydraulic or screw based that require a lot of time and energy for bending rods. So here we propose a compact and pneumatic based rod and pipe bending machine that bends pipes and rods as per angle set by user. This system uses pneumatic piston, pipes, valves, hinges, supporting frame and electronics mechanism to achieve accurate bending. It use pneumatic piston attached to a movable bed that is attached to the supporting frame using hinges for vertical movement. This bed is used to support the materials to be bent. Then use the supporting frame to mount the rod support and holders. Now here use electronic sensors to get reading of the bending angle. User is allowed to select the angle at which bending is needed. As per users settings made the system operates the pneumatic system once user starts bending process. The system now operates the pneumatic cylinder automatically until desired bending has been achieved. This machine demonstrates the concept of fully automatic pneumatic bending system. Here we mainly bend rod and pipe (3mm to 5mm stranded). This system is able to bend rod and pipe in three angle. This is 20 degree, 45 degree and 70 degree. We added 2 data table of our result chapter. This paper data table understand for rod and pipe bending takes same time but vary the pressur
