  • @baconbots
    @baconbots 3 года назад +1

    this looks like it would be quite a convenient tool for binding belts together. At my shop we made something similar, consisting of a locking clamp with steel plates welded on the jaws, and holes drilled thorugh them to stack another plate on it. then we'd screw them together with the belts clamped between and use a heat gun to melt the ends and then lock the clamp in and wait to dry. the whole process only works half of the time because of misalignment. this tool is great, because it does that all so much better.

      This tool is used to weld PU belt profiles. These belts are used for industrial transport and conveying applications, e.g. conveying light goods in the food industry (cheese, sausage) or in intralogistics.
      The tool welds very quickly and, above all, very reliably. This means that there are no long downtimes in these applications.

      Not a pipe. It is a solid belt.

    Awesome, you could make a giant Hot Wheels racetrack without those plastic connectors that you always lose.

    so basically, your just melting one piece of rubber/plastic onto the other end of the same material and letting it cool, its legit no different than using a lighter to do the same thing but its much better at doing it but takes more steps.

    the most useful case I can make for this is for small waterline welding. But you couldnt weld pipe because the material would build up on the inside.

    • @littlejackalo5326

      It's not pipe. It's a solid piece that is used as a belt to transmit power between two (or more) pulleys.

      For that application it might be possible to design a tool that uses ultrasonic frequencies. That way the translation is kept low but the energy is maintained high enough to generate a weld. A tool like this would be expensive due to the engineering needed to optimize the piezo-crystal and horn.
