What is Tungsten Carbide Die?
Tungsten carbide dies are tools made from tungsten carbide, a very hard and durable material, used in a variety of machining and forming processes. Tungsten carbide is an alloy composed primarily of tungsten and carbon, and it is known for its exceptional hardness, which is second only to diamond. This makes it ideal for use in dies where high levels of abrasion resistance and strength are required.
Cemented carbide is a kind of tungsten carbide powder + cobalt points + other carbide powder, through powder metallurgy pressing sintered composite materials. Tungsten carbide is a kind of high hardness material, through high temperature sintering "glue" metal cobalt (nickel) melting tungsten carbide particles together, forming the tungsten carbide we use. The role of cobalt (nickel) in cemented carbide is similar to that of a "skeleton". Cobalt content changes the hardness of tungsten carbide will also change, the more cobalt content, the lower the hardness, and vice versa, the lower the cobalt content, the higher the hardness. The finer the particle size of tungsten carbide powder, the higher the hardness, and the coarser the particle size of tungsten carbide powder, the better the impact resistance.
Used as mold tungsten carbide is an excellent material. High hardness, good abrasion resistance, corrosion resistance, impact resistance and other characteristics make Cemented Carbide as mold material is almost a perfect material solution.
- Fine-grained cemented carbide grades, such as Yatech's YU20 tungsten carbide particle size of less than ≤1um, cobalt ≤8%, HRA92-94
Suitable for the manufacture of metal wire drawing, pipe drawing molds, but also suitable for the manufacture of powder metallurgy molds.
- Double crystal grains of cemented carbide grades, such as Yatech's YF40H tungsten carbide particle size less than 0.4-3.0um, cobalt ≤ 15%, HRA88-90
Suitable for the manufacture of motor cores, silicon steel sheets, metal lead frames and other high-speed stamping progressive mold punches, concave molds, inserts and so on.
- Coarse-grained carbide grades, such as Yatech's YF55H tungsten carbide particle size less than 0.4-3.0um, cobalt ≤15%, HRA88-90.
Carbide die material selection needs to be considered comprehensively, the hardness of the stamped material, thickness, stamping speed, mold precision, stamping equipment precision and other issues.
What are the machining methods for Tungsten Carbide Die?
Electrical discharge machining
Electrical Discharge Machining, wire erosion or spark erosion, is a non-traditional machining process that relies on electrical discharges (or sparks) to remove material particles from workpieces made of conductive materials. The process is particularly well suited for producing complex or fine holes and features in metal parts, as EDM machining is capable of achieving tolerances within +/- 0.005 mm and therefore provides high precision.
Unlike other machining technologies, EDM is characterized as a non-contact process. This means that the tool is never in physical contact with the workpiece. Instead, a series of successive electrical charges are sent from a power source through the tool (called an electrode), which creates an electric arc between the electrode and the workpiece. The sparks generated by this electrical reaction are highly targeted and erode particles on the workpiece in a controlled manner. Being submerged in a dielectric fluid, these particles can be safely flushed away from the electrode and workpiece surfaces.
Diamond tool cutting and grinding (machining centers)
- Electroplated Diamond Cutting Blades
Precision parts processing plant can not be separated from cemented carbide, we often see the cemented carbide processing technology is cutting. Cutting is one of the commonly used ways of undercutting cemented carbide rods, plates and wires. For grooving or cutting below 1mm, diamond ultra-thin cutting blades are commonly used for processing.
Diamond resin matrix type cutting discs, in which the outer ring band is the resin bond abrasive working layer, the center part of the high-strength and high rigidity of the metal material, generally used for medium and large depth of cut grooving and cutting.
In the process of turning carbide parts, the hardness of the tool itself must be higher than the hardness of the workpiece to be processed, so at present, the tool material for turning and processing carbide parts is mainly made of high hardness and high heat-resistant non-metallic binder and diamond.
When cutting carbide parts with hardness less than HRA90, we generally choose BNK30 CBN tools for large margin turning. When cutting carbide parts with hardness greater than HRA90, we generally choose PCD tools made of CDW025 or use resin bond diamond wheels for grinding.
- Electroplated diamond grinding head
When processing complex curved shapes, holes and threads, you can use electroplated diamond grinding head of high-speed CNC machining centers for grinding, which has the characteristics of high efficiency and high dimensional accuracy. - Other diamond tools
For the milling process of cemented carbide parts, according to the customer's demand, we can provide CVD diamond coated milling cutter and diamond inserted milling cutter for precision parts machining, which can replace the electrolytic corrosion and EDM process to improve the production efficiency, and product quality.
Laser processing
Laser perforation machine is currently the most outstanding of all perforation equipment, laser perforation through the laser generator focused high-density energy on the surface of the workpiece, so that the workpiece is irradiated on the region of local instantaneous melting and gasification, this process lasts a very short period of time, milliseconds within the completion of the process, you can quickly form holes or holes in the groove. Especially applied in
Carbide laser drilling do not have to worry about burrs, it is non-polluting, high-precision processing, processing of the perforated surface is very smooth, without the need for subsequent reworking and polishing, reducing the tedious process. Processing in non-touch processing, the laser head will not be in contact with the material surface, do not have to worry about scratching the workpiece, there is no mold loss, only need a simple package can be very convenient.
Cemented carbide stamping die refers to the use of cemented carbide to manufacture the upper or lower die, or upper die, lower die are made of cemented carbide stamping die. The upper die and lower die can be made of the whole piece of cemented carbide, or a piece of cemented carbide can be glued or set on the steel part as the working part for stamping, and a layer of cemented carbide can also be sprayed on the edge of the steel stamping die. Because of the high hardness and abrasion resistance of cemented carbide, the life of cemented carbide stamping die is several times to dozens of times higher than that of general steel stamping die. Because of the brittle nature of cemented carbide and the impact load in the stamping process, the cemented carbide commonly used in stamping dies are YF40H, YF50H, YF55H and so on.
The upper and lower molds are made of cemented carbide. The structural form of the stamping die is similar to that of general stamping dies, but it also has its characteristics. Now, according to the characteristics of cemented carbide itself, it explains the problems that should be paid attention to when designing the stamping die of cemented carbide.
Cemented carbide due to more brittle, can not have too much deformation force, all in the design of the material, need to pay attention to the location of the first cutter, can not only punch half a hole, so as to avoid the die bending fracture.
material belt than the normal stamping design to be larger, and should be greater than the material thickness, so as to avoid the material belt is too small in the stamping was squeezed into the die.
die clearance in the normal clearance on the basis of the appropriate increase in margin.
choose a good rigidity of the die frame, stamping molds on the selection of various parts and components to match the high life of the lower die. Such as the upper and lower die holder are made of steel, and to be about 1.5 times thicker than the general stamping die. Positioning nails, guide plate and other accessories made of 45 steel and quenched. The back of the upper and lower molds should be thickened and quenched.
The guiding accuracy and service life of the die holder should be high in order to be compatible with the high service life of the lower die. Often use rolling guide mold frame and interchangeable guide pillar, large or complex workpiece commonly used 4 guide pillars. Generally, floating die shanks are commonly used to overcome the influence of press error on guiding accuracy.
The upper and lower mold can be made of the whole piece of tungsten carbide, can also be used in the form of mosaic. Can also be bonded or welded on the steel parts.
If the unloading plate is used to unload the material, the unloading plate should be prevented from hitting the lower mold of cemented carbide, so that the lower mold is not uniformly loaded and cracks are produced. For this reason, the height of the unloading plate should be higher than the height of the guide plate – the height of the thickness of the material is 0.05-0.01mm lower, then the unloading plate only play a role in unloading the material does not play a role in the pressure of the material. Stamping thin material must be pressed stamping, can be in the unloading plate and the lower die or the upper die between the fixed plate to increase the guide column, guide the unloading plate uniformly pressed workpiece.
