AXIAL ROLLING HEAD RC4014: FILLING A GAP
Fast processes, high-precision threads, perfect surfaces - the advantages of thread-forming with LMT Fette rolling systems are overwhelming. But what are you supposed to do when there isn?? enough room available around an external thread - for example, at the bolt on a common rail pipe - and the rolling head is too large? LMT Fette is offering the perfect solution for this and similar threading tasks in the shape of the new RC 4014 axial rolling head.
Take a common rail pipe, for example. These components have several bolt immediately next to each other with little distance between them. Conventional rolling heads could not be used for such applications in the past, because a tool with a diameter of approximately 100 millimetres would not fit in the space between. ??he gap is simply too small. So instead other processes had to be used, often cutting techniques, which, however, have disadvantages with regard to the surface quality of the thread and the processing time,????says Tilo Knobelsdorff, who is responsible for the development of thread rolling tools at LMT Fette. "That was also why there was a concrete customer request for a smaller, much more compact rolling head that can be used on a common rail pipe."
So the experts decided to enter this new territory. The existing standard tool was reduced in diameter from 100 to only 40 millimetres. A special challenge here was the tool?? mechanism. In a standard model, it ensures that the thread rollers inside the rolling head open after the thread rolling process to allow the tool to be withdrawn from the finished thread without making further contact. ??his solution is very difficult to realize in such a compact rolling head. Its mechanical components would have to be much smaller and more delicate. However, that would have a negative impact on the system?? stability - and that is unacceptable in a rolling head. After all, this system has to withstand extremely powerful forces," explains Knobelsdorff.
Small rolling head with great market potential
LMT Fette?? solution is as simple as it is effective: the new RC 4014 axial rolling head makes do without the conventional mechanism to open the rollers. Instead the tool is simply removed from the thread in the opposite direction after the forming process. In order to do that the tool must be able to turn in both directions on the machine. ??hat?? not a problem for modern CNC equipment," says Knobelsdorff. All the advantages of thread rolling remain untouched: it is possible to produce an M14x1.5 thread with a length of 12mm in less than two seconds ????with a polished, burr-free surface. ??he result is far superior to using a cutting process for all the well-known reasons,????reports Knobelsdorff. |
