The cemented Carbide Punch is entirely made of cemented carbide round bar, which has the characteristics of high precision, high hardness and good bending strength.
The cemented carbide punch is a part on the cemented carbide die, also called the cemented carbide punch or the cemented carbide punch, mainly used for punching hardware parts or electronic parts, of course, other nonmetals can also be punched Parts, even belt holes, plastic holes, etc.
Cemented carbide, also known as tungsten steel, refers to a sintered composite material composed of at least one metal carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, and tantalum carbide are common components of tungsten steel. The grain size of the carbide component (or phase) is usually between 0.2 and 10 microns, and the carbide grains are bonded together using a metal binder. The binder usually refers to the metal cobalt (Co), but for some special purposes, nickel (Ni), iron (Fe), or other metals and alloys can also be used.
The matrix of cemented carbide consists of two parts: one part is the hardened phase; the other part is the bonding metal. The bonding metal is generally an iron group metal, and cobalt and nickel are commonly used. Therefore, there are tungsten cobalt alloys, tungsten nickel alloys and tungsten titanium cobalt alloys.
Production Process
Ingredients (Main ingredients: WC + TiC + TaC + Co + VC + --) → Full mixing → Crushing → Drying → Adding molding agent after sieving → Re-drying → Sieve to obtain the mixture → Granulate, press and mix → Low pressure sintering → blank after sintering → inspection (non-destructive ultrasonic flaw detection) → blank dimensional accuracy inspection → EDM (or wire cutting) → rough grinding → fine grinding → polishing → inspection → marking → packaging.
Product Usage
Its application field is very wide, because of its anti-acid and alkali, rust-proof and long service life, the pharmaceutical industry specially selects the punch used to make stamped tablets. The manufacturers that are used more in the pharmaceutical industry include Federal Pharmaceutical and Sanjin Pharmaceutical Industry, Sanjiu Pharmaceutical, etc.
