Description
Technical field
The present invention relates to a kind of daggers and swords, and in particular to dragon's fountain day good fortune sword and its manufacture craft.
Technical background
During very long social development, substantially being made using medium carbon steel or high-carbon steel for traditional sword body is raw
The double-edged sword of production gets rusty easily corrosion during using and preserving.The riffled iron forged is exactly folded by hand this similarly be present
The problem of sample.Double-edged sword is during using this is collected, often because playing or being gone to touch the sword body of double-edged sword, sweat on hand with hand
Easily double-edged sword is set to get rusty.Plum rain season is run into use simultaneously and wet weather easily causes sword surface oxidisation.
In addition, existing double-edged sword have one it is obvious the characteristics of, be exactly that its bending resistance is often relatively low when its hardness is very high；And work as
When its flexural strength is very high, its hardness is again relatively low.Such as prior art Authorization Notice No.：CN103741051B Chinese invention
Patent, used by a kind of sword body preparation method sword body of the disclosure of the invention alloy have the chemistry of following degree into
Point：C 1.2-1.4%, Si 0.5-0.7%, Mn 0.10-0.20%, Cr 23.0-24.0%, Ni 0.3-0.5%, Ca 0.30-
0.50%, Mo 0.15-0.25%, V 0.2-0.4%, Nano diamond 0.4-0.6%, remaining for surplus Fe and total composition not
Impurity more than 0.1%.Sword body made of the invention is not easy corrosion, and elastic camber, hardness are more excellent.
The content of the invention
The present invention provides a kind of sword knife edge profit, hardness height, with forging the firm one kind of decorative pattern to solve above-mentioned technical problem
Dragon's fountain day good fortune sword and its manufacture craft.
It is of the invention to be for the taken scheme that solves the above problems：A kind of dragon's fountain day good fortune sword and its manufacture craft, including sword
Body and scabbard, wherein：
Alloy is made up of the chemical composition of following degree used by its Fujian sword body：Mo 0.15 ~ 0.25%, V
0.1 ~ 0.3%, Mn 0.12 ~ 0.20%, Si 0.3 ~ 0.5%, C 1.4 ~ 1.6%, Cr 20.0 ~ 24.0%, Ni 0.6 ~ 0.8%, Ca
0.2 ~ 0.4%, Nano diamond 0.6-0.9%, remaining is no more than 0.1% impurity for the Fe of surplus and total composition.
Nano diamond refers to the diamond particle that average path is 400nm ~ 500nm nanometers.
A kind of day good fortune sword manufacture craft, comprises the following steps：
The preparation of sword base：Alloy is made up of the chemical composition of following degree used by sword body：Mo 0.15~
0.25%, V 0.1 ~ 0.3%, Mn 0.12 ~ 0.20%, Si 0.3 ~ 0.5%, C 1.4 ~ 1.6%, Cr 20.0 ~ 24.0%, Ni 0.6 ~
0.8%, Ca 0.2 ~ 0.4%, Nano diamond 0.6-0.9%, remaining is no more than 0.1% impurity for the Fe of surplus and total composition,
Crude green body with the much the same shape of sword is made in steel raw material using punch press, then is placed in forge furnace and calcines, calcining heat is 649 DEG C ~
982 DEG C, soften to form sword base；
Water breakthrough：Sword base charge and attack by hand, while flicks sword body repeatedly, sword base is subjected to water breakthrough step after charging and attacking, then
It is repeated 1 times above step and calcines-charge and attack-water breakthrough；
See oil：Calcining heat is calcined-charged and attacked to sword base obtained by upper step process as 649 DEG C ~ 982 DEG C again, carries out seeing oil
Step, sword body is obtained, it is in order that double-edged sword is more flexible to see oil；
Normalizing：Sword body is put into forge furnace and reheats heating, normalizing temperature is 700 DEG C ~ 982 DEG C, is being allowed to cool down, normalizing
Purpose be granulation steel, after sword body is heated to certain temperature, it may occur that austenitizing, can so reduce due to sword body composition
It is irregular caused by stress, and ensure the consistent of whole sword body particle；
Annealing：Sword body obtained by upper step process is made annealing treatment with wrapped with insulation, annealing temperature is 700 DEG C ~
982 DEG C, the purpose of annealing is to allow steel to soften, and is easy to polish and cuts；
Grinding and buffing：Grinding-fine grinding-polishing；
Salt bath：Liquid is dissolved into salt heating, allows sword body to be suspended in 1 ~ 3h in salt bath, the use of salt bath, because of fusion temperature
The salt lower than the temperature of steel fusing, after this temperature, salt will remain in that liquid, thus be provided for blade splendid
" heating bath " condition, heat steel to salt uniform and complete；
Sword body obtained by upper step process is put into quenching tank, the purpose of quenching is that cementite is enclosed in ferrite, system
A kind of stone steel is produced, is called martensite；
It is tempered and produces sword body；
Wherein, during above-mentioned charge and attack, a small amount of alloy should be added on sword sword carry out folding and charge and attack.
The a small amount of alloy added on sword sword by following degree chemical composition：Obsidian 10 ~ 20%, In 0.10 ~
0.25%, Nano diamond 0.6-0.9%, remaining is no more than 0.1% impurity for the Fe of surplus and total composition, and increase sword sword is hard
Spend and allow sword sword sharpness to increase significantly, while surface has lines in layer, turn into that to forge decorative pattern firm, it is very attractive in appearance,
Reserve value is very big.
Normalizing temperature is 720 DEG C ~ 736 DEG C, temperature control, makes sword under austenitizing, with the tissue being stabilized；
Annealing temperature is 723 DEG C ~ 731 DEG C, temperature control, makes sword under austenitizing, with the tissue being stabilized；
Being tempered concrete operations is：Thick clay rib will be covered with whole sword, in the case where temperature is 649 DEG C ~ 727 DEG C, entered
Row tempering, keeps temperature quenching-annealing again for a period of time, repeats 3 ~ 6 times, wrapping portion should be than other portions of sword body
It is point slightly soft, pliability can be increased, and sword sword should then keep hard, repeatedly annealing obtains accurate hardness level, makes steel
Hardness keeps sharp sword sword enough, but hard must can not become fragile, because may so cause tipping or fragmentation.
Compared with prior art, advantage for present invention is：
1st, sword body of the present invention forms and forges riffled iron, has great reserve value.
2nd, sword knife edge of the present invention is sharp, elastic camber, hardness are superior, and is not easy corrosion.
