Anvil
An anvil is a metalworking tool consisting of a large block of metal (usually forged or cast steel), with a flattened top surface, upon which another object is struck (or "worked"). Anvils are as massive as practical, because the higher their inertia, the more efficiently they cause the energy of striking tools to be transferred to the work piece. In most cases the anvil is used as a forging tool. Before the advent of modern welding technology, it was the primary tool of metal workers. The great majority of modern anvils are made of cast steel that has been heat treated by either flame or electric induction. Inexpensive anvils have been made of cast iron and low quality steel, but are considered unsuitable for serious use as they deform and lack rebound when struck. Structure The primary work surface of the anvil is known as the face. It is generally made of hardened steel and should be flat and smooth with rounded edges for most work. Any marks on the face w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Forge
A forge is a type of hearth used for heating metals, or the workplace (smithy) where such a hearth is located. The forge is used by the smith to heat a piece of metal to a temperature at which it becomes easier to shape by forging, or to the point at which work hardening no longer occurs. The metal (known as the "workpiece") is transported to and from the forge using tongs, which are also used to hold the workpiece on the smithy's anvil while the smith works it with a hammer. Sometimes, such as when hardening steel or cooling the work so that it may be handled with bare hands, the workpiece is transported to the slack tub, which rapidly cools the workpiece in a large body of water. However, depending on the metal type, it may require an oil quench or a salt brine instead; many metals require more than plain water hardening. The slack tub also provides water to control the fire in the forge. Types Coal/coke/charcoal forge A forge typically uses bituminous coal, ind ...

Blacksmith At Work02 Less Contrast
A blacksmith is a metalsmith who creates objects primarily from wrought iron or steel, but sometimes from other metals, by forging the metal, using tools to hammer, bend, and cut (cf. tinsmith). Blacksmiths produce objects such as gates, grilles, railings, light fixtures, furniture, sculpture, tools, agricultural implements, decorative and religious items, cooking utensils, and weapons. There was an historical distinction between the heavy work of the blacksmith and the more delicate operation of a whitesmith, who usually worked in gold, silver, pewter, or the finishing steps of fine steel. The place where a blacksmith works is called variously a smithy, a forge or a blacksmith's shop. While there are many people who work with metal such as farriers, wheelwrights, and armorers, in former times the blacksmith had a general knowledge of how to make and repair many things, from the most complex of weapons and armor to simple things like nails or lengths of chain.

Forging
Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer (often a power hammer) or a die. Forging is often classified according to the temperature at which it is performed: cold forging (a type of cold working), warm forging, or hot forging (a type of hot working). For the latter two, the metal is heated, usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.Degarmo, p. 389 Forging has been done by smiths for millennia; the traditional products were kitchenware, hardware, hand tools, edged weapons, cymbals, and jewellery. Since the Industrial Revolution, forged parts are widely used in mechanisms and machines wherever a component requires high strength; such forgings usually require further processing (such as machining) to achieve a finished part. Today, forging is a major worldwide industry. History Forging is one of the oldest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hardy Tools
Hardy tools, also known as anvil tools or bottom tools, are metalworking tools used in anvils. A hardy has a square shank, which prevents it from rotating when placed in the anvil's hardy hole.''The Complete Bladesmith'', p. 10 The term "hardy", used alone, refers to a hot cutting chisel used in the square hole of the anvil. Other bottom tools are identified by function. Typical hardy tools include chisels A chisel is a tool with a characteristically shaped cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on its end, for carving or cutting a hard material such as wood, stone, or metal by hand, s ... and bending drifts. They are generally used with a matching top tool. Different hardy tools are used to form and cut metal. The swage is used to make metal a specific cross section, usually round for final use as nails, bolts, rods or rivets. The fuller is used to stretch or help bend metal, and make dents and shoulders.

Hundredweight
The hundredweight (abbreviation: cwt), formerly also known as the centum weight or quintal, is a British imperial and US customary unit of weight or mass. Its value differs between the US and British imperial systems. The two values are distinguished in American English as the "short" and "long" hundredweight and in British English as the "cental" and the "imperial hundredweight". * The short hundredweight or cental of is used in the United States. * The long or imperial hundredweight of 8 stone or is defined in the imperial system. Under both conventions, there are 20 hundredweight in a ton, producing a " short ton" of 2,000 pounds and a " long ton" of 2,240 pounds. History The hundredweight has had many values. In England in around 1300, different "hundreds" (''centum'' in Medieval Latin) were defined. The Weights and Measures Act 1835 formally established the present imperial hundredweight of 112 lb.

Pritchel
A pritchel is a type of punch used in forging, particularly in making nail Nail or Nails may refer to: In biology * Nail (anatomy), toughened protective protein-keratin (known as alpha-keratin, also found in hair) at the end of an animal digit, such as fingernail * Nail (beak), a plate of hard horny tissue at the tip ... holes in horseshoes. The horseshoe is heated and a hole is punched through 90 percent of the steel with a forepunch or drift punch. The pointed end of the tool should be kept sharp and so that the burr is cut out smoothly. The punched hole is lined up over the pritchel hole and the pritchel is driven into the hole, knocking out the remaining metal at the bottom of the punched hole. The temperature of the pritchel should be always below the ''red-hot'' stage as the tool itself will bend and lose the temper. When over-heated it is advised to cool it in water intermediately. Back pritcheling The pritchel should normally be driven from the bottom of the shoe, si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Hammer
Power hammers are mechanical forging hammers that use an electrical power source or steam to raise the hammer preparatory to striking, and accelerate it onto the work being hammered. They are also called open die power forging hammers. They have been used by blacksmiths, bladesmiths, metalworkers, and manufacturers since the late 1880s, having replaced trip hammers. Design and operation A typical power hammer consists of a frame, an anvil, and a reciprocating ram holding a hammer head or die. The workpiece is placed on the lower anvil or die and the head or upper die strikes the workpiece. The power hammer is a direct descendant of the trip hammer, differing in that the power hammer stores potential energy in an arrangement of mechanical linkages and springs, in compressed air, or steam, and by the fact that it accelerates the ram on the downward stroke. This provides more force than simply allowing the weight to fall. Predecessors like trip hammers, steam drop hammers, bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metalworking
Metalworking is the process of shaping and reshaping metals to create useful objects, parts, assemblies, and large scale structures. As a term it covers a wide and diverse range of processes, skills, and tools for producing objects on every scale: from huge ships, buildings, and bridges down to precise engine parts and delicate jewelry. The historical roots of metalworking predate recorded history; its use spans cultures, civilizations and millennia. It has evolved from shaping soft, native metals like gold with simple hand tools, through the smelting of ores and hot forging of harder metals like iron, up to highly technical modern processes such as machining and welding. It has been used as an industry, a driver of trade, individual hobbies, and in the creation of art; it can be regarded as both a science and a craft. Modern metalworking processes, though diverse and specialized, can be categorized into one of three broad areas known as forming, cutting, or joining proc ...
