In-Die Tapping Units (FTU)

subject to alteration▶ FIBRO 2

FIBRO In-Die Tapping Units allow the production of threads in a progressive die. This avoids additional expensive processes outside the die tool. The modular design of these FIBRO In-Die Tapping Units with flexible components allows a custom adaptation to any tooling situation. Furthermore, one or more threads can be tooled simultaneously at angles other than 90°. FIBRO In-Die Tapping Units can therefore be utilised in a broad spectrum of applications. All of the basic components are quickly and easily removed and can be reused in other tools. A sophis-ticated design and the use of robust parts guarantee a long life cycle and production reliability of all FIBRO In-Die Tapping Units. Threads are cold formed, not cut, which eliminates swarf. Cold formed threads are more durable than cut threads, as the grain structure of the material is not interrupted. FIBRO In-Die Tapping Units can produce threads up to M16. And by selecting the right components for the job, stroke rates of up to 200 strokes/min (depending on thread diameter) can be achieved.

Advantages of FIBRO In-Die Tapping Units: no additional processes required for threading modular, flexible design Threads can be produced in any angle position Several threads produced simultaneously Robust and safe mechanical solution

Examples for Application (see below):Left: Two FTUs in one progressive die.Right: Five FTUs with 14 chucking heads in one progressive die.Below: Sample parts

Functional Principle & Mode of Operation: When the FTU is integrated into a progressive die, the press stroke is transformed via the toothed rack and drive unit into a rotational movement. This rotational movement is then transferred to the chucking head via the drive mounted drive wheel and intermediate wheels. The press stroke provides the feed motion for the chucking head. The FTU is elastically supported to provide pitch compensation and spring pressure for gating the thread.

Multiple Tapping:By adding more gearwheels and chucking heads, several - even different - threads can be formed simultaneously (or with the next cycle) in one single FTU. The type table provided contains recommended values for max. numbers of threads for each of the FTUs indicated. Multiple Tapping in a progressive die:

Types: FIBRO FTUs are classed into various types. Select an FTU to match the size and number of threads to be produced.

Spring units:Depending on application, mechanical spring units for FTUs 10, 20, 30, and 30P (helical compression spring) should be replaced with pneumatic springs. For the FTUs 11, and 21, only double-action spring units can be used. The FTUs 40 and 40P come with a single-action pneumatic spring unit as standard.

Core Hole Diameter for Formed Threads:Due to material displacement, core hole diameters are larger than in thread cutting. The core hole diameters pro-vided here are guideline values only. The actual core hole diameter is to be determined during production, as it is dependent on the flowability of the material used, as well as the speed in which it can be formed.
