Hello to all lovers homemade. In this article I will tell you how to make a hole punch for metal do it yourself, which is useful in creating holes in sheet metal, as well as other materials.
In the assembly of this homemade product you do not need any hard-to-reach parts, enough automotive parts.
Before you start reading the article, I suggest watching a video in which the assembly process and testing of a homemade tool are shown in detail.
In order to make a hole punch for metal with your own hands, you will need:
* Car steering rod
* Valve
* Cutting from turning tools
* Disc mill
* Metal Lathe
* Welding machine
* Welding mask, gaiters
* Hammer
* 2 mm thick metal plate
* Two M6 bolts
* Spring, washer
* Gloves, safety glasses, earphones
* Angle grinder, cutting disc
Step one.
We install a disk mill in a three-jaw chuck of a lathe for metal with a special mandrel, but if you have a milling machine, you can make a groove on it.
Then, in the tool holder, we fix a segment of an unnecessary cutter and milling a groove in it. In the process of milling, we drip a little technical oil onto the cutting edge, so the cutter will last longer and will not wedge into the parts.
As a result, upon completion of milling, such a groove is obtained.
Step Two
We clamp the steering rod into the tool holder and make the same groove with a disk mill on a lathe.
Then we set the thrust in a vice and, using a drilling machine, make a hole with a diameter of 6 mm.
The result is such a hole, with a larger drill we make a small chamfer.
In the cutter section with the groove, we make the same hole as in the tie rod. In two workpieces in one of the two holes we cut the M6 thread using a tap.
Step Three
Next, you need to make the movable part of the hole punch. To do this, a broken drill, tap or, as in this case, an automobile valve, is suitable. The valve is clamped in a vice and, using an angle grinder with a cutting disc, saw off a stock about 3 cm long. When working with the angle grinder, be careful when wearing safety glasses, gloves and earphones.
On this rod we make a small recess for fastening in the handle from two sides, and also sharpen its reverse side in the manner shown in the photo.
Step Four
To install the rod in the handle, we make a recess using a drilling machine, drill smaller holes on the sides, pins made of ordinary nails will be installed in them.
You also need to cut a 2 mm thick plate from sheet metal, and then drill two holes in them with a 6 mm drill.
Step Five
It's time for welding.
We weld two cuts of the cutter to the steering link with a small gap relative to each other, and one should be about 15 mm longer than the other.
When working with the welding machine, be careful and use a welding mask and gaiters.
After welding, remove the slag with a hammer and clean the seam with a metal brush mounted on a screwdriver.
Next, you need to drill a hole in the welded sections of the cutters on a drilling machine with a metal drill of 6 mm. All the details of this homemade product are ready, now you can assemble the tool and test it in real conditions.
Step Six
After assembly, you get such a hole punch made by yourself.
We will check it on paronite with a thickness of 2 mm, the holes are made easily and without much effort, and the installed spring on the movable rod returns the handle to its original working position.
We try the tool on a sheet of metal, it copes with this task quite well. When folding the sheet in half, the hole punch also makes holes perfectly, despite the fact that there is no big lever here.
This hole punch is useful when working with sheet materials in which it is necessary to quickly and evenly make holes of the same diameter. In this case, the diameter of the holes made with a home-made hole punch is 6 mm; if necessary, this parameter can be changed if a rod of the required diameter is made.
That's all for me, thank you all for your attention and creative success.
