Dengeln (also known as Dängeln , Dengelen , Tängeln , Demmeln , Dümmeln , Haren or Klopfen in regional parlance ) describes a process for sharpening the edge of a scythe , sight or sickle , in which it is driven out to a thin, sharp edge by hammering. The cutting edge produced is referred to as a dengel or regionally a dengel.

process

The scythe, sifting or sickle blade is drawn out and thinned and thus sharpened in a narrow strip along the cutting edge (the peg) through targeted blows. This thin cutting edge is worn away over time by the mowing work and the regularly required sharpening . A scythe that is used a lot therefore has to be re-gelled more often. A hammer and anvil are mostly used for peening, but an ordinary blacksmith's anvil with a well-preserved face can also be used. In addition, there are other tools, such as the dengeler (dengel apparatus) or a hammer to shape the dengel of the scythe leaf. Common to all tools is the driving of the scythe blade into a very thin 3–7 mm wide peg.

Reasons for Dengeling

Dengeling is used to permanently maintain, improve or rebuild a thin and thus sharp edge of the scythe or sifting blade or the sickle. At the same time, any nicks can be worked out of the blade during peening, which can easily arise when mowing through contact with foreign objects such as stones in the crop. The cold deformation of the blade during peening increases the hardness of the cutting edge. This is why the cutting edges of scythe blades, scythe blades or sickles have a much longer service life than those made by grinding.

Tool

Dengelhammer

The peening hammer , also known as the scythe hammer , is a hammer for peening. It has a head weight of 250–600 g. Due to the special shape of the hammer, the cutting edge of the scythe can be easily driven forward when peening. The Dengelhammer has two fins , sometimes also a fin and a track . The peening hammer should be hardened. The fin is offset towards the handle. The hammer fin and the possibly existing track are cambered so that only a small point of the cutting edge can be hit when peening.

Peening anvil

The dengel anvil is a comparatively small anvil with either a square, usually flat arched or narrow, cambered path. On the underside of the track there is a pin with which the peening anvil can be attached by hammering it into a wooden stake or peening stick . There are also pestle anvils that are suitable for direct use in the field. For this purpose, these have a corresponding bulge, which then rests on the ground and prevents deeper hammering into the ground. This is usually passed through the mandrel of the anvil. For the use of such an anvil, the hardness of the soil into which it is to be hammered is relevant, so that hold can be generated, but the anvil is no longer hammered into the soil.

In principle, when using a peening anvil and peening hammer, it should be noted that one side is always flat and one side is pointed, but the direction in which the combination is made is variable. The underside of the scythe blade points to the flat side, or the pointed side drives the peg out on the top of the scythe blade. The pointed side is always aligned parallel to the peg.

Devices

There are also devices in which a mechanically moved hammer is combined with an anvil in one machine. Sometimes a seat is also nailed to the wooden stake. This is called a peening stick or peening bench.

Dengeln in turbine construction

The surfaces of turbine blades , impellers or blisks are usually shot peened . The balls hitting the surface level any unevenness, harden the surface and thus fulfill the function of peening. To avoid shot peening, the finished surfaces can also be peened with a piezo hammer directly in the machining center. The process was developed in 2014 by the Starrag company.

Broader meaning

At the latest since its onomatopoeic use as an inflective in the Werner Comics (“dengel, dengel”), the verb dengeln has also been used in the figurative sense for processes that produce hammering noises.

So you would be back closer to the original word understanding of Dengeln or Tengeln as hammering or pounding in often faster rhythmic sequence and the resulting sounds. The name Dengelmännchen used to stand in Switzerland for the woodworm that creates noises in the wooden walls, ceilings and stairs that are reminiscent of the pecking of a clock or the passage of time. According to popular belief, this indicates a death in the house, which is why it was called the dead clock like the beetle . This, in turn, is closely related to the idea that death or the devil comes as a reaper and shortly beforehand dengles his tools (see also Dengelgeist , Dengelstein ).
