Production method of Damascus steel sword

Abstract

The invention discloses a production method of a Damascus steel sword. The method comprises the following steps that pig iron, puddling steel and iron meteorite are weighed according to a proportion of a raw material for a first time; high-temperature forging is conducted on the raw material to form a sword blank strip; the sword blank strip is repeatedly heated and bonded through transverse folding, and after the transverse folding is completed, the sword blank strip is forged to a length of a sword body to form the sword body; according to a pre-configured distance, pattern outlines of the same sizes are cut on the sword body from top to bottom; the pig iron, the puddling steel and the iron meteorite are weighed again according to a proportion of a raw material for a second time, and the proportion of the raw material for the second time is different from the proportion of the raw material for the first time; the raw materials are folded to cast parts with the same sizes with cut patterns; and the cast parts with the patterns are inserted into outlines left after the sword body is cut, and the whole sword body is returned to a furnace to be heated and forged, so that production is finished. According to the method, the raw materials with the two different proportions are adopted for forging combination, then different patterns can be generated, types of the patterns are rich, meanwhile, the production cost is greatly reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of knife forging, in particular to a production method of a Damascus steel sword. Background technique [0002] The distinctive feature of Damascus steel is the intricate water-like pattern on the surface of the steel. These patterns are commonly referred to as damascus patterns. The steel has excellent toughness and fracture resistance; the blade is extremely sharp, and has long been considered the king of weapons in the cold weapon era. [0003] At present, there are mainly two kinds of existing Damascus steels, namely domestic Damascus steels and imported Damascus steels. Domestic Damascus steel is made by folding and forging two kinds of stainless materials, and its forged pattern is naturally formed, which is also a natural irregular pattern. Its melting point is difficult, the cracking rate is 5 times that of carbon steel folding forging, the hardness is about 53, the cost is high, the output is low...
