BUILDING THE BENDING MACHINE.
There are only a few main important points to consider in building this bending machine.
Firstly, if not using particle board as we did, at least use a strong, rigid wood or metal for the main base and folding parts. Any flex of the base or clamp boards will degrade the quality of metal bends, especially in thicker sheet materials.
We would not recommend using particle board thicknesses anything less than 15mm (and if done again from wood, we would possibly double up the 15mm board, or use a 30 mm thick particle board).
Secondly, use extremely sturdy metal hinges with little or no give in the joints (ie: backlash).
The hinges need recessing into both the base board and the folding board such that the axis of the hinge joint sits flush with the line of fold (between the base board and the folding board). A wood router or CNC machine will be a great help in cutting this recess if available, but the job can also be done manually with a little careful chisel work.
While the cutout doesn’t have to fit the hinge area exactly, it is important that the depth is at least accurate and that the folding edge between the base boards is positioned to be close and well seated. The more accurate this is, the sharper, cleaner and more precise the final bends will be.
Screw the hinges into the base board and folding board with solid screws!
A standard drill can be used to make the required bolt holes in the base board and clamping board.
When drilling the holes, use wood clamps to fix both boards tightly together in position and ensure the clamp board edge and the intended folding edge are aligned correctly before drilling through both boards at the same time. Remember to allow for the width of the aluminum strengthening strip.
Keep the holes tight around the bolts so the thread is able to grip in the wood of the base board. Glue the bolts in if necessary. We don’t want the bolts to turn or fall out through the bottom of unit when the clamping board nuts are loosened or removed from the top of the unit.
Screw or glue additional lengths of particle board to the underside of the base board (as in the photos) to allow the unit to sit flat on a table without the bolt hexagonals protruding through the bottom.
The clamping board holes then need to be drilled out to be slightly larger than the M8 bolts. This allows the clamp board to slip over the top of the bolt threads easily.
Use round drill holes in the clamp board only if your bending machine is going to be used for relatively thin sheets of metal or plastic (eg: 0.5mm to 2mm thick).
If wanting a unit which also handles thicker acrylics and plastics, use adjustable slots in the clamp board instead. The slotted holes allow us to adjust the inner folding edge away from the bending point of the base board when bending thicker acrylics and plastics.
We built a machine with the slotted hole clamp board option. The slots were made using a CNC machine.
RESULTS.
We were impressed with what we had produced in such a short time and by great job it did!
2:30 - Example of Bending Machine.
I like to diy very much. A lot of handmade things are very usefull in ordinary life. How to make different things? What craft of crafts should I choose? Constuction is anothe side of creativity. In this field you must be able to make insulation and padding, waterproofing and repair or reperation, fix and pluster ect.
