Hello to all homemade products! In Today's article, I will try to describe and show you in detail the manufacture of one interesting homemade product, namely, we will assemble today such a useful tool as a manual metal plate bender. This is a rather useful tool for those who often work with metals; you yourself know about its usefulness in everyday life, and there is no need to talk about it again. Factory-made tools like these are quite expensive, and if you are not some kind of professional, you hardly want to spend a lot of money on a factory-made analog. In addition, our homemade instrument will already surpass most of its Solomon brethren. The tool itself will be assembled from the simplest possible materials. Well, well, I think you shouldn't delay with a long preface, let's go.
To make this homemade product, we need the following, namely:
– Long bolt with a diameter of 10-15mm (depending on your requirements for the finished tool)
– Also a long, but narrower bolt
– Nuts for the bolts you have taken
– A square metal rod 15-20mm wide (their width will also further affect the capabilities of the finished tool)
– Metal tube 15-20mm
– A metal tube of such a diameter that inside the canvas could get the tube mentioned earlier.
– Thick metal plate
– Ball bearings 5-6pcs (the simplest)
– Metal washers
From tools you will also need the following:
– Drilling machine
– Set of various drills
– Grinder with cutting and grinding discs
– Welding machine with all the attributes necessary for working with it
– Building corner
– Vise < br> – Some kind of paint to protect metal from corrosion (optional)
Making a metal strip bend:
First of all, as it usually happens, we need to start with the main part of our structure, in our homemade product the base itself will be the main part. We will use a bolt as a base. There are no exact bolt sizes, you can act on your own or use exactly what you have at hand. It is worth noting here that the wider the bolt is, the more reliable the structure will be. We need to put on some nuts on the bolt we took.
In the future, the handle will be welded to the nuts put on the bolt. The number of nuts depends solely on the size of the nuts themselves, if you have a large and thick bolt on which you can screw a large and thick nut, then you will naturally only need one single nut. But in the case of the author of this homemade product, he needed to fasten three nuts. It is also worth noting that there are various nuts in hardware stores and, accordingly, even a relatively narrow bolt can be screwed on one long nut. If you also have several nuts, then just weld them together in the same way as the author did it in the photo below.
After several nuts have been welded together, it is necessary to grind the welded seams and the nuts themselves, respectively. Grind them so that the nuts look like a single monolithic part. Otherwise, you just simply will have problems when assembling this homemade product in the future.
Then we need to take a square metal rod. As in the case with the bolt, with which we worked earlier, the capabilities of our existing tool depend on the width, that is, the wider the metal rods you take, the thicker the metal you can “take” for bending. But here it is worth noting the not unimportant fact that these two above-mentioned elements equally affect the properties of the finished tool, well, that is, if you take a narrow bolt, you will not need to look for a wide metal square rod, because there will be no use from it, since without bending the rod, you will bend the bolt itself. So make sure that the width of these elements matches each other.
As it was not difficult to guess from the square metal rod you took, it is necessary to saw off a couple of identical segments, the length of the segments, as well as the width of the rods themselves, we choose individually, the maximum width of the metal strips directly depends on the length of these rods, the strips of which will be possible to bend with the help of the future tool. Having cut off the rods, they must be welded to the bolt of length.
We will weld the newly cut square metal rods to the head of the bolt itself, so in order for us to do this and do it reliably, we need to cut one groove in the rods themselves. We apply the rods to the bolt as shown in the photo below, mark with a marker the place where the cap ends, the main thing is that everything is symmetrical. The depth of this “L” shaped groove will affect the width of the metal strips that can be bent with this tool.
Having marked the places for the saw cut on the square metal rods, we install our rods in the sheets and, using a grinder and a cutting disc, carefully saw off the groove along the contour. Again, I repeat, at this stage it is important to make two even and identical blanks. Having cut out the grooves, we immediately grind the workpieces with a grinding disc.
After grinding the blanks, we weld them in their place, namely to the head of the large bolt, just as shown in the photo below. Having welded the workpieces well, we grind the welded seams and the parts themselves, as before with the nuts to give a monolithic look.
Let's move on to the next step. For it we need a small piece of metal tube, preferably a thick-walled tube made of good metal, not silumin. The diameter of this tube should not exceed or not greatly exceed the size of the nuts screwed on the bolt, since it is to them that we will weld this tube.
Before welding this tube, one through hole must be drilled in it. The hole must be made a little, stepping back from the edge (see photo below). A second, narrower bolt will be inserted into this hole, which means that the diameter of this hole should be such that the bolt you took is sitting tightly in it. I advise you to drill using a drilling machine, as the author of the homemade product did it, so it will be easier to drill an even hole in the center.
Having drilled a through hole in the tube, we weld it to the nuts on a large bolt perpendicular to the bolt itself, in order to set a right angle and not beveled, I recommend using a construction angle. After welding, do not forget to grind the welded seams.
Next, we need to take care of securing our future instrument. No matter how difficult it is to guess, the load on our instrument will be quite large, which means that for it we just need to make some kind of solid fastening or go according to the “low resistance” method and do it like the author of a homemade product. Namely, he decided to fasten this tool in a vice, which, in turn, is already firmly fixed to the table. So, in order to fix our tool in a vice, you need to do the following. Take a small metal plate and weld it to the bolt on the back of the head, having previously cut a groove in the bolt for this very plate.
Next, we make the folding stop ourselves. Everything is simple here, we insert a long bolt into the welded tube, no less than the length of the square metal rods. We fix it with a nut, then we put several bearings on it, and on the other hand we fix them with a nut, not forgetting about the metal washers (see photo).
Everything is ready, it remains only to insert the second pipe into the welded pipe. This pipe is just a lever-handle. The longer the lever, the easier it will be for you to bend the metal strips. It remains to paint the homemade product in order to protect it from the harmful effects of corrosion. And you can safely use it. Below is a photo of a homemade product at work.
