Description

Technical Field

[0002] The regulating valve assembly is mainly composed of a valve body, a valve core, a valve stem, etc., among which the valve stem is one of the most important metal components in the regulating valve and plays an important role in the normal operation and performance of the regulating valve. The valve stem is usually made by cutting a carbide rod and then performing turning, milling, heat treatment and other steps.

[0003] The cutting method of cemented carbide rods is usually to first fix a single cemented carbide rod or multiple cemented carbide rods with a clamp, and then cut the cemented carbide rods in sequence with a cutting blade. After cutting, the clamp is released, the cemented carbide rod is moved to the required cutting length, and then the cutting process is performed again.

[0004] However, the current cemented carbide rod cutting process has the following problems: manual operation of the fixture is required to clamp and loosen the cemented carbide rod during cutting, resulting in low processing efficiency; and because the cemented carbide rods are cut one by one, the cutting blade will idle after each cemented carbide rod is cut, and will move a certain distance before cutting the next cemented carbide rod, further reducing the overall efficiency of the cemented carbide rod cutting process.
