What Is Hand Forging?

Manual forging is a primitive and ancient method of forging processing. It has a history of 2,000 to 3,000 years in China. It is a forging that is completely relying on manpower and using some simple tools. Before humans entered industrial production, most metal utensils, especially daily utensils, were hand-forged, ranging from royal utensils such as gold and silver utensils used by the court to pots, basins, and pots used by ordinary people. The most suitable metal for forging is copper because it has the best ductility. During continuous tapping, the metal becomes harder and harder, but after annealing, it becomes softer. The thin copper sheet can be bent even by hand even after the fire has just finished. Sterling silver is also a very soft material, and its plasticity is also very strong during forging ^[1] .

Although the manual forging method is backward, due to the tools and

Hand forging tools can be divided into three categories according to their functions and uses; basic tools, auxiliary tools, and measuring tools.

Basic tool: The tool used to directly deform the blank is called the basic tool.

Auxiliary tools: Tools that are only used to grip, flip and move blanks or forgings. Such as various clamps.

Measuring tool: A tool used to measure the size or shape of blanks and forgings. Such as ruler, caliper, template, etc. ^[2]

Smoke and dust removal manual forging furnace belongs to the general stove for heating. The design uses a face-focusing reflection furnace roof consisting of a circular refractory furnace and an arc-shaped top ring, a swirling flue, a double cone smoke hood, and a swirling secondary air system consisting of coils, secondary air ducts and steam tubes And smoke albino system. It can eliminate most of the smoke and dust in the furnace, which not only improves the thermal efficiency and saves energy, but also has a good smoke and dust removal effect. From the start of ignition, it can meet the national environmental protection emission standards of GB3841-83 in the first to second regional targets. The smoke-removing and dust-removing hand-forged furnace built with refractory material is composed of a hearth, a flue, a double cone smoke hood, a furnace door, and a grate. Swirling secondary inner system consisting of tubes, steam tubes and coils; swirling vanes forming swirling flues; inner and outer smoke hoods forming double cone smoke hoods; water jacketed cone smoke boxes and safety The smoke exhaust albino system composed of pipes ^[2] .
