A blacksmith using pliers Slip joint pliers Cutting wire with diagonal pliers/side cutters. Pliers are a hand tool used to hold objects firmly, possibly developed from tongs used to handle hot metal in Bronze Age Europe. [1] They are also useful for bending and physically compressing a wide range of materials.
In metalworking, forming is the fashioning of metal parts and objects through mechanical deformation; the workpiece is reshaped without adding or removing material, and its mass remains unchanged. [1] Forming operates on the materials science principle of plastic deformation, where the physical shape of a material is permanently deformed.
Press tools are commonly used in hydraulic, pneumatic, and mechanical presses to produce the sheet metal components in large volumes. Generally press tools are categorized by the types of operation performed using the tool, such as blanking, piercing , bending , forming , forging , trimming etc.
A red-hot metal workpiece is inserted into a forging press. Plastic deformation involves using heat or pressure to make a workpiece more conductive to mechanical force. Historically, this and casting were done by blacksmiths, though today the process has been industrialized. In bulk metal forming, the workpiece is generally heated up. Cold ...
The slapper is great for working metal over a T-stake, or for gouging and planishing. A good slapper can make radius bends and crowns quite well. A slapper works well with forming stakes and post dollies for lightly planishing and pulling cold shrinks. [1]
