Basics of tungsten carbide molds and considerations

Tungsten carbide mold is made of tungsten carbide, which is an alloy material made of a hard compound of refractory metal and bonded metal through the powder metallurgy process. Tungsten carbide mold has a series of excellent properties such as high hardness, wear resistance, better strength, and toughness, heat resistance, corrosion resistance, etc. Especially its high hardness and wear resistance, even at a temperature of 500 ℃ also basically remain unchanged, at 1000 ℃ still has a high hardness. So do you know the machining process of carbide dies? Let's have a look.

Basic knowledge of carbide dies

In the metallurgical industry, tungsten carbide tooling replaces the common metal tooling, which can make the life of the tooling increase dramatically, and the tungsten carbide tooling has better benefits in the metallurgical industry production, and the tungsten carbide tooling has excellent performance.

Tungsten carbide molds are widely used in the processing of metals, mining development, engineering excavation, petroleum geological drilling, mechanical wear-resistant parts, diamond production, and so on.

In recent years, molds made of tungsten carbide have been widely used in the metallurgical industry, which is very meaningful to expand the application of tungsten carbide molds and accelerate the development of cemented carbide industry. Cemented carbide is divided into two categories: ordinary cemented carbide and steel-jointed cemented carbide gold, which are made of refractory metal compounds (such as WC, Tic, NBC, Vc, etc.) and bonded phases, and are produced by powder metallurgy methods. The bonding phase of ordinary cemented carbide is mainly nickel and cobalt, etc., while steel-junction cemented carbide is made of steel as the bonding phase. Because of the high melting point of the basic carbide elements, some properties are higher than those of various steel and other metallic materials produced by casting methods.

The tungsten carbide mold body includes a mold body with a cavity, the mold body is a split structure, and the mold body includes a plurality of side plates and a bottom plate, all of which are distributed along the circumference of the bottom plate, and all of which form a cavity between the side plates and the bottom plate, and the side plates and the bottom plate are made of steel plates, and the side plates are welded to the bottom plate, and two adjacent side plates are welded. The mold body also includes a ring-shaped enclosure plate, which is welded to all side plates, and the enclosure plate is made of steel plate. The side plates are welded with ribbed plates, said ribbed plates are made of steel plates. At least two side plates are welded with a casing and a trunnion is mounted in the casing, which is used to connect to the lifting device. The trunnion and the casing are interference fit. The trunnion is connected to the casing by a key. The side plate extends in the upper and lower directions, and the lower end of the side plate is welded to the bottom plate, and the cross-sectional area of the cavity gradually increases from the bottom to the top. The length of the upper end of the side plate is greater than the length of the lower end of this side plate.

Tungsten carbide mold selection considerations

According to the chemical composition, mechanical properties, physical properties, and other parameters of the stretching parts to choose the material of the tungsten carbide mold, the stretching parts production batch is small. Choose ordinary steel; choose good quality impact-resistant and wear-resistant steel for the large production batch.

High precision requirements of the parts, choose good quality, quenching deformation of steel, low precision requirements, choose general steel.

The shape of the tensile parts is complex and difficult to process, choose good quality steel. Also consider the processing performance of the tungsten carbide mold, heat treatment, and surface treatment performance. The possibility of change or breakage in the process of use, the change in the state of hot processing and heat resistance, cold resistance, assembly, welding, and riveting performance, but also consider the economics of tungsten carbide mold materials and market supply.
