In-Die Tapping Units (FTU)

In-Die Tapping Units 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 sophisticated design and the...

In-Die Tapping Units 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. Spring Unit Types: FIBRO FTUs are classed into various types. Select an FTU to match the size...

In-Die Tapping Units 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.

In-Die Tapping Units Tables & Formulae: The press stroke required for a rotation of the tap is calculated with the values provided in the following table. Other transmission ratios can be provided for non-standard models. FTU 10 Drive wheel diameter (d1) recommended for thread sizes Overall length Z (marked as Z* in the type diagrams) changes depending on thread diameter and the associated standard length tolerances of the tap. Adjustments in regards to the relevant tool situation can be carried out via the spacer washer. FTU10-25 / 10-25-5 Required press stroke Ca for feeding with a feed angle...

In-Die Tapping Units Core Hole Diameter for Formed Threads: Due to material displacement, core hole diameters are larger than in thread cutting. The core hole diameters provided 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.
