Steel rings are used to decorate metal gates, fences, gates, balusters of stairs and balconies. They are welded between the rods, allowing you to get an original, beautiful lattice. Such rings are inexpensive, but since they often need hundreds of pieces, the purchase costs a significant amount. To save money, you can make a simple bending machine, and bend such rings from strips or rods, which is several times cheaper.
- Steel pipe equal to the diameter of the required rings;
- bar 8 mm;
- profile pipe 20×20 mm;
- corner 30×30 mm.
Machine manufacturing process
It is necessary to select a pipe equal to the diameter of the rings to be obtained. A workpiece with a width of 20-25 mm is cut from it.
It unfolds along and stretches to fit tightly on top of the pipe.
A profile pipe is welded to the resulting expanded ring over the gap. This will be the bending lever. The longer it turns out, the less effort will need to be applied when bending the rings.
A hole is drilled in the pipe in front of the ring. A piece of a rod with a diameter of 8-10 mm is inserted into it and welded. It should protrude 20 mm from the pipe on one side.
Next, you need to take a piece of a corner of 100 mm. A metal plate is welded to its edge at right angles to the entire width of the shelf. A pipe with a length of 150-200 mm is welded on top of the corner. The gap between it and the plate should be 10 mm.
Half of the machine with a corner is clamped in a vice. Then a ring with a lever is put on from the top of the fingers down. To perform bending, it is necessary to lay a strip of steel or a bar obliquely upwards between the pipe and the plate. The workpiece is caught by the lever finger and wound up.
The resulting spring cuts lengthwise.
As a result, you can get several rings at a time. They are trimmed with a hammer and their edges are welded. Then the rings can be used as intended.
