Hello everyone, I'm going to make myself a fence, the total length is 68 m. And it's time to make a gate and a gate, I decided not just to do it as it goes, but also to make it beautifully with decorative elements and forging. I am not an expert in this matter, but I think the Internet will help me with this. I was looking for a suitable pattern for a long time and finally I found it.
To repeat such a pattern, elements of semi-arcs and rings are needed. In the network I saw that using a special device like a pipe bender to make such elements. Well, I decided to assemble a pipe bender for myself. There are many manufacturing options on the network, both with and without turning work, just then the case turned up and they turned the shafts to me, gave me a yoke with bearings, well, it seems that everything is there now, it just remains to collect everything in a heap.
I need a pipe bender mainly to bend a 20 mm profile, but I decided to make a semi-serious machine right away. The most problem is to find a yoke and grind the shafts, and everything else can be found under your feet and so I consider the preface complete, I proceed to execution.
You will need a tool
- Electric welding
- Locksmith's toolbox
- Protruba or I-beam
- Yoke and shaft
- Rod from car pillar
- Round timber for handle
- Old jack is desirable hydra
For the main frame, I use a profiled tube 20 x 40 mm. The length of the frame itself will turn out to be 70 cm, and the width is 10 cm. I roughly figured out how the two extreme yokes would stand, I weld everything with Electric Welding. To fasten the bushels themselves, I weld eight bolts of m 10. The extreme shafts have a diameter of 32 mm so that they go into the bearing on a lathe, a little unnecessary amount of metal is removed. I put everything in its place and tighten the bolts so that nothing dangles during further work. I do everything along the way, so there is no size, what I came up with, I welded it on. The pipe bender itself will not be disassembled, only the bearings will be removed for replacement, otherwise I will simply put it on the table and firmly fix it and it will not move anywhere else. If suddenly I made a powerful machine, I would have to use thick-walled metal or even an I-beam, I will bend decorative parts with a wall thickness of up to 2 mm.
The main roller is experiencing a load and if you make it from ordinary metal it will wear off very quickly and that is why I decided to make it from the rod of the rack. Everyone says that the rod is made of shx15 steel with surface cementation, which means that it will be strong and less wear-resistant. My stock got hollow, I cut off a piece of the required length and, to make the handle, I picked up a round timber according to the inner diameter of the stock, hammered it into the stock and welded it around the edges, then made cuts in the place of bending, heated it and bent it, then welded it. So all such a roller will last longer than ordinary steel, I think this is a good option, but I am confused by the place of welding, I think it will fall off someday I hope not in my hands.
For the mechanism of movement, I used an old threaded jack; there is no better, of course, to take a hydra, it will press harder and there will be less strength left. On the jack itself there is a sole, which rests on the ground, I weld on it pieces of the profile to hold the jack. For the main mechanism, I cut off 4 pieces of a square 20 by 20 mm by 40 cm and welded onto the frame, welded thoroughly because there will be a considerable load.
To fasten the yokes of the main roller, I welded a profile of 20 by 40 mm and two of the same profile across and welded the whole thing onto the upper sole of the jack. I welded everything, everything works, it rises and is released to fasten the yoke, but I pre-welded the bolts to the pile place. I put it in its place and I thoroughly boil everything to bequeath with a clear and where I did not boil it again. Well, that's all that remains to bring the appearance of the structure in order and you can create. After the locksmith work, I degrease and paint with a grinder. That's all the pipe bender from the trash is ready, it remains to buy the profile you need and you can work. In the meantime, I tried on different pieces everything bends as it should, one minus is the effort of the jack, I still have it under the tired, then I will replace it with a hydraulic one so it will be easier and this one until the main thing comes off, it works. I uploaded a video about the assembly on YouTube, please, support the newbie. In general, I am satisfied with the work, everything works beautifully, and most importantly it is free and necessary in the household. Thank you all for your attention and friends before new homemade products.
