Sewing machine-About Sewing machine:

In the sewing machine manufacturing, enterprises are using alloy cutting tools for the job, the advantage of easy to wear, more stable size, processing speed, is the processing center and special machine an ideal tool used more.

How can we improve the tool life of it? Here we introduce some effective way. Our welding blade, the weld is generally placed in the air after cooling, insulation is not the tool for cooling, which would speed up the phenomenon of thermal expansion and contraction tool, the tool produces fission of soft tissue, the structure is not close, there are numerous small cracks and other tools, this is the tool does not lead to durable, easy to wear and tear of the main blade.

We all know that the tool is in the process can not be used coolant, so easily lead to methods of operation increased blade cracking, and this phenomenon can not see the eyes alone. The temperature in the welding tool should be above 1000 ℃, if suddenly cooled in the air, which is faster but the cold heat faster tool processing operations process (cutting tool in the processing operations in the heat of about 400 ℃ -500 ℃) suddenly increases coolant for cooling the truth is the same, easily lead to the powder structure of the tool becomes unstable.

Blade is made of metal alloy powder composed of over 100 tons of press by pressing and then sintered at high temperature. This is our common stone on top after long-term wind and rain, sun Ye Lu, the large stone into small stones, but also numerous loose "weathering" process, so too alloy blade is very fragile, but also because of this principle.

Tool for thermal processing in the application of industrial furnace conditions, the welding tool immediately placed in a good furnace (furnace temperature should not be less than 600 ℃) with the furnace temperature slowly cooling down; no conditions available lime thermal cooling, the welding tool immediately buried in a good lime slowly cooling, heat 6 hours.
