Introduction:
As a typical representative of super-hard metal, the high hardness of hard alloy is a good choice for wear-resistant parts, especially valve core and valve core sleeve for the automation of precision equipment. It requires high precision and outstanding wear resistance performance. The cemented carbide produced by powder metallurgy technology has the advantages of high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance and small coefficient of linear expansion. It is one of the excellent tool materials, widely used in many industrial production and processing operations. The cemented carbides have particularly outstanding physical stability, especially its excellent wear resistance. Carbide wear parts are widely used for the core working parts of precision equipment. The valve core, the valve core sleeve, the plunger rod and the plunger sleeve used on the dispensing valve need to be slid back and forth frequently. It is a very good choice to use cemented carbide as the material.
Technical parameters:
The carbide alloy valve core used in the rubber control equipment has a high precision requirement. The position tolerance of the valve core φ8 diameter is -0.005 (negative 5 micrometers), and the position tolerance of the φ8 inner diameter is +0.005 (positive 5 micrometers), position concentricity of φ15 outer diameter and φ8 inner diameter is 0.002 (2 micrometers), verticality requires to be 0.002 (2 micrometers). The valve core and valve sleeve are used together, and there should be smooth and no obvious shaking. The geometrical tolerance should be well matched. The finish of the mating surface should be 0.2~0.4, and the precision of the mating surface should be 0.008mm~0.01mm. The precise dimensional tolerances are all in line with the long-term effective use of the rubber-controlled automation equipment. For the cemented carbide machining, the precision requirements for tungsten steel non-standard customization are relatively high.
Advantages:
We specialize in the production of wear-resistant parts and accessories for precision equipment, especially precision carbide products with high geometric tolerances. We can also provide non-standard customized production to meet the special requirements of customers, like the internal machining of carbide wear-resistant products. High wear resistance is the basic requirement of cemented carbide products. Especially for the requirements of progressive molds, combined molds and multi-station molds, cemented carbide products has the excellent performance of long-lasting operation.
