Young metallurgists, participants of the exhibition NTTM-78, developed a key for their production needs: screwing graphite electrodes Ø 300 mm electric steel furnaces. However, they believe that the principle laid down in its design, applicable and to create a tool with the other, but a close target (for example, for unscrewing the studs).
The proposed device is extremely simple in terms of device and method of use. It is a steel rim or tape, the ends of which are hinges; they are used to fasten a ribbon on the strap with holes and a handle. Depending on the diameter of the part Unscrew the bolts of the hinge ends of the rim are inserted in certain holes and the tool is ready to work.
Tape key:
1 — metal strip, 2 — hinge, 3 — plate with holes, 4 — arm, 5 — spikes.
When you turn the handle the other end of the rim rests in the detail, and the rim fits snugly around her, rotating in a predetermined direction. To improve the adhesion of it with the detail on the inner side of the rim welded steel spikes with a height of about 3 mm.
