Spring Making / Wire Bending Machine

Well, this machine is not only about making springs. It is a wire bending machine capable of bending 0.8/0.9/1 mm wire into any 2D shape. But yeah, the coolest thing I was able to make with it so far was the spring. How cool is that?Get more news about spring forming machine producer,you can vist our website!

The main goal was to make it quite precise. Other DIY wire bending machines are not very precise and their bends tend to have quite a big radius. I like to work with nice sharp bends!

The second goal was to make it as easy to build as possible with commonly available parts and components. All the structural parts are 3D-printed and all the metal parts are available in most of the hardware stores.

Why I build this? Check out my other creations. I am a passionate free-form electronic circuits artist and this awesome machine will ease my job when doing repetitive tasks or when there are a need identical parts.

I've tried to record the whole build to help you understand it. It's always better to see the build in action. Continue with steps below to collect all the material and start building step by step!
All the STL files for the plastic parts are available in the project's GitHub repository. Download them and start printing. I always design the parts to omit the need for using supports so the post-processing is much easier and parts are cleaner.

I was printing with 0.15mm layer height, 3 perimeters and 40% infill with Gyroid pattern setup. It does not matter if you use PLA or PETG. The parts will not get hot so PLA is just fine. Below is a list of all the parts that you will need for the build. See you in 2 days! (That's the print estimated time).
While you are printing the plastic parts let's have a look at how the wire bender works and what components it consists of (from right to left):

Spool holder - it holds the spool of wire for the machine to process.
Straightener rollers - set of 7 rollers to make the wire as straight as possible. Working with straight wire is crucial. That's also why there are 2 of them in a row.
Feeder - you can find a similar mechanism in your 3D printer. A set of gears that pull the wire from the spool, through the rollers and pushes it to the bending head. The feeding gear must have enough drag on the wire so it will not slip thus making the machine inaccurate. More on that later.
Bender - by rotating the pin on its head it bends the wire into programmed shape.
It is all controlled by a single Arduino UNO with a CNC shield. Arduino takes commands from computers and translated them into movements of the stepper motors. Like any other CNC machine.
