Greetings to all lovers of homemade products and those who just looked at the site in search of interesting ideas that you can take note of. Today you will learn how to quickly and effortlessly make a press from scrap metal, the author uses a 10 ton hydraulic car jack as its main element. Yes, the idea is not new, and the site has many options for this device. But they are all different in performance, therefore, I think that this one is also quite worthy to replenish the model range of the presses presented here, if only because it is simple to perform and does not require special materials and tools. So even a beginner DIYer can make such a design. If you are interested in the idea of vases, you are welcome, read the article, watch the video below and take a note.
* hydraulic jack,
* section of channel, width 12-14 cm ,
* profile metal pipe with a cross-section of 50×25 mm,
* metal corner 50x50x5 mm,
* bolts and nuts, as well as long studs with a diameter of 7 mm,
* scrap sheet metal with a thickness of about 8-10 mm,
* two springs,
* spray paint for metal.
* welding machine,
* drilling machine,
* cutting disc machine,
* drill or screwdriver,
* magnetic corner,
* marking tool (marker, tape measure, square, vernier caliper),
First of all, the author starts by preparing the materials. First of all, he takes a channel of a suitable length (it is selected individually, it all depends on where the press will be used and installed, well, just do not forget about the stability of the structure). The author cleans the channel with a grinder and processes it with a cord-brush with a nozzle.
Next, the author takes a profile pipe. Looking ahead, I will say that the author will use it for the manufacture of racks. The author first butts the pipe on a cutting disc machine. Then he measures the first part with a tape measure. The length is about 1 m (here, too, everything is selected at your discretion). Cuts off. Then, using this part as a template, mark and cut off another one of the same.
Next, you need to cut a corner, in the photo there is a cross-section (maybe I could be mistaken). But before you cut it, you need to decide on the distance between the posts. Therefore, the author first marks the installation locations of the racks on the channel base. Having decided on the indents from the edges and the optimal distance between the posts, the author takes measurements and, guided by them, is determined with the length of the parts for the corner. Cuts six workpieces on a cutting machine. What they will see next.
At this stage, the author starts building. He takes the racks, puts them on the base and tries on the first pair of corners. Using a magnetic square, welds the parts to the upright in turn on both sides of the uprights, as shown in the photo. This will be the upper part of the structure.
The resulting frame, if you can call it that, the author installs on the channel-base, while fixing it only with a magnetic angle, here you need to properly mark everything, which he actually does. With the help of a tape measure, marks are applied to the racks, a fully divorced jack is inserted, the author places a corner under it and also puts the appropriate marks.
Next, the marked part of the frame is moved by the author to the drilling machine and drills two holes according to the marks in each rack, first with a step drill, then enlarges them with the usual metal for a hairpin with a diameter of 7 mm.
Re-installs the frame on the base and tries on the corner to it. Place marks on the shelf under the holes. Drills holes in the corners along the edges with a diameter of 7 mm. Further, the corners are attached to the racks with pins. This is the bottom fixed stop.
Here is the fitting of the jack on the base. The support metal plate for the tool is also visible here.
Next, the author removes the jack and plate and takes the last pair of corners. A movable stop will be made of them, on which the jack will rest. Their location is shown in the photo below.
Now you need to weld the corners together so that you get a movable part of the structure. To do this, the author cuts off from the departure of the 50×25 mm profile pipe two blanks with a length equal to the width of the corner shelf, that is, in this case 5 cm (but if I was not mistaken). The author also processed their edges on a grinding machine.
Setting aside the corners for now, the author welded the posts to the base. Then the author turned the already finished frame upside down and welded a stop plate under the upper part of the jack to the already welded corners. So that he does not accidentally jump off. I picked up a round pipe, cut off a sleeve from it and welded it onto a plate.
Now the author returns to the remaining corners. Fixes them on the racks with a clamp and welds the previously prepared inserts from the profile pipe between them.
Next, the author installs the second base plate. Already under the bottom of the jack. On the one hand, it welds a threaded rod with a nut to it, this working part of the press.
Then this part is turned upside down with a pin down, a jack is installed on the plate, everything is set evenly and welded.
At this stage, the author installs the springs. To fix them from below in pipe inserts, he drills holes. To fasten the springs from above, the author makes grips from threaded rods and metal plates. First, he welds nuts to the ends of the studs. As shown in the photo.
At this stage, the author installs a jack between the movable part of the press and the upper crossbars, by rotating the nuts on the upper studs, aligns the movable part strictly horizontally. All the press is ready.
At the final stage, the author paints the press frame. Then he proceeds to test the structure. First, the bearing is pressed in and out.
Then the author demonstrates his pressure.
Well, at the very end, the author changes the working part with a flat end, to the same one, but sharpened like a chisel. It can be used to cut through thick stranded cables. Something like this, below is the promised video.
