Cold heading machines (also commonly referred to as “heading machines”) are specialized equipment based on the theory of metal plastic deformation. They operate by applying pressure to metal wire at room temperature using dies to perform heading forging. This causes plastic deformation within the die cavity, transforming the metal wire into parts with specific shapes and dimensions. This process enables the mass production of fasteners such as screws, bolts, and rivets. At room temperature, cold heading machines apply pressure to metal blanks, inducing plastic deformation within the die cavity to process the metal into parts of specific shapes and dimensions.
The basic workflow includes multiple sequential processes—cutting, heading, upsetting, and forming—which can be automatically completed in sequence.
Core Advantages：
1.High Production Efficiency: Utilizes automated continuous production, achieving speeds far exceeding traditional processing methods.
2.High Material Utilization: Multi-station automatic cold heading machines achieve material utilization rates of 80% to 90%, with minimal chip generation, significantly reducing material costs.
3. Stable Product Quality: Mechanical forming ensures high dimensional accuracy and consistent product quality.
4. Superior Surface Finish: Work hardening enhances surface strength and hardness of components.
5. User-Friendly Operation: Flexible inch-by-inch control facilitates easy debugging.
6. Wear-Resistant Key Components: The machine body is cast from alloy-enhanced ductile iron, while the main slide employs high-wear-resistant alloy steel plates, ensuring sustained precision and stability during prolonged high-speed operation.
7. Forced Lubrication System: An effective lubrication system minimizes mold wear during high-speed machine operation.
8. Eco-Friendly and Energy-Efficient: Room-temperature processing eliminates heating energy consumption and associated pollution.
