The anvil is one of the oldest basic tools of humanity. Even before metal processing, hard, durable and specially shaped stones and rocks served as work surfaces. In order to be able to bend and round off workpieces, the typical asymmetrical anvil shapes developed.
Four basic moldings
Anvil molds are based on the workpieces that are to be processed on them. The greatest possible versatility makes versatility possible. The more different angles and rounding curves are present, the easier it is to bring workpieces exactly into the desired shape.
The actual work and work surfaces consist of four anvil parts. The upper bearing surface is referred to as anvil path. The two tapering and pointed ends of the ends of the band are the horns. They can be rectangular or rounded. In a so-called Voramboss is a laterally protruding Bahnnase. The upsetting anvil is an additional block attached to the lower part of the foot.
Anvil and workpiece shapes
The combination of all elements is suitable for the universal workshop. Typical anvil shapes consist of a one-sided circular horn. On the opposite side the horn runs out into a triangular shape. The weight ratio between the horns and the middle part must be selected so that the outer edges and tips of the horns are guaranteed to remain secure during massive loading. Many anvils have cantilever feet for increased stability.
Of course, the anvil forms were created primarily for the forging work with hot or glowing metals. However, the different application and lay-up options and angles make it possible to process every malleable material. The classic shapes that are possible for workpieces are:
- Rounding and arching
- Bending components with selectable bending angles
- Right-angled creases
- Fastening and connection by riveting
- Making funnel patterns
Load carrying capacity and resistance
An anvil is normally made of heavy iron and has hardened surfaces. Therefore it serves as a support for all changes of shape made with great force. Usually, the workpiece is machined with a hammer. Therefore, in particular, the tips of the horns must be able to deliver unbreakable resistance to the impacts.Tips & TricksYou must consider the impact of force on the working environment both in the anvil substructure as well as the self-construction or substitute use of anvil-like work surfaces. A useful anvil weighs at least a hundred kilograms.
