With the rapid development of fastener industry, in order to meet the needs of high speed production, Cemented Carbide Cold Heading Die has gradually replaced the initial alloy tool steel die is widely used, it is mainly used for direct contact with the parts of the workpiece, the Cemented Carbide as a mandrel pressed into the steel material coat, its more wear-resistant, more efficient, and service life is increased dozens of times to dozens of times, it is to improve the enterprise's production efficiency and economic efficiency of the choice! Choice.
Cemented Carbide Cold Heading Die is a kind of mold used in cold heading process, usually made of Cemented Carbide / Tungsten Carbide. Cold heading is a kind of metal forming process, by applying pressure to the metal blank in cold state, making it undergo plastic deformation in order to manufacture various shapes of parts. Cemented Carbide, due to its high hardness, abrasion and impact resistance, is very suitable for use as a cold heading mold material, especially when processing high strength metals.
Characteristics of Cemented Carbide cold heading dies include:
High hardness: the hardness of Cemented Carbide can reach HRC 70 or above, enabling the mold to maintain its shape under high pressure.
High abrasion resistance: suitable for processing large quantities of workpieces, it can maintain dimensional accuracy for a long time and reduce the need for frequent mold replacement.
Good impact resistance: In the process of cold heading, the molds need to withstand great impact, and Cemented Carbide has high impact resistance.
Corrosion resistance: Cemented Carbide has excellent corrosion resistance and can be used in harsh environments.
Application field
Cemented Carbide cold heading molds are widely used in the manufacture of bolts, nuts, rivets, shaft parts and other high-strength fasteners and other parts. These molds are especially important in automotive manufacturing, aerospace, machinery manufacturing and other industries.
1. All kinds of metal and non-metallic powder molding and stamping, compression rate of steel bars, steel pipe stretching, the amount of work under greater stress top forging, piercing and stamping molds, machine parts, mold core, making stamping molds, such as stamping watch parts, musical instruments spring sheet, and so on;
2. Stamping molds for battery shells, toothpaste skins;
3. Stamping dies for small-sized steel balls, screws and nuts, impact-resistant forging dies and making cold heading, cold punching and cold pressing dies for standard parts, bearings, tools and other industries;
4. Stamping dies for bullets and cartridge cases.
