Fences can be defined as arrangement that provides an obstruction, enclosure, or a boundary, made up of posts or stakes linked together by boards, wire, or rails. The chains run vertically and are bent into a zigzag pattern so that each “zig” hooks with the wire immediately on one side and each “zag” with the wire immediately on the other. The manufacturing of chain-link fencing is called weaving.
Preparing zigzag shape wire is a quite challenging task and cannot be done using basic mechanisms. So here we design a smart mechanism to automatically bend wires in order to get zigzag shaped wire for mesh. These wires can then be linked together to create chain link or meshes. For this system we make use of a wire bobbin to supply raw wire to the system, a DC motor with shaft connected to a unique mechanism that achieves our bending requirements. The system is a small yet complex system that achieves the task with ease.
When the DC geared motor is powered it rotates thus rotating the rectangular rod attached to its shaft. Now this rectangular rod is fixed to rotate inside a hollow round tube. Milling operation is performed on this tube to achieve a spiral shaped cutout on this hollow tube.
So Now as the rectangular rod rotates inside this hollow tube. We now take the wire end from the bobbin and hook it on the inside rod through the hollow tube slot. We now turn on the machine. As the motor runs, the rod turns inside the hollow tube. As the hollow tube is cutout in a spiral shape, the wire moves with the rod spiralling around it and moving outwards.
So now we get a zig zag shaped wire coming out of the other end. Thus the system provides a fast and easy way to develop zigzag wires for chain link or mesh making.
