For the first time ever, a fully automated process to produce beads with no holes, one hole or very small holes directly from a tube
Until now, these beads could only be produced from a forged plate by furnace welding the two halves of the bead. Tube production means that the waste resulting from cutting the halves, the subsequent forging, and the work needed to join them can be avoided. Moreover, it is possible not to use a welded plate.
High production flexibility thanks to the combined use of specific moulds and machine programming.
Bead drilling by means of cutting tools. The bead is drilled by a high-speed milling cutter, so that it is possible to choose among a wide range of hole diameters.
1. Obtaining closed beads directly from the tube.
2. Drilling a single side of the beads obtained from the tube.
3. Making two or more staggered holes with a 90° or 180° precision increment which can be obtained by means of drill cutters.
We have designed progressive molds which allow a drastic deformation of the tube, up to the point where it closes on itself. (closed beads). We have furthermore created an extra device which allows the cutting and drilling of the beads as soon as they are removed from the molds, thus making it possible to get to the final product within the machine cycle.
