Precision Cold Heading at Its Best.
The Four-station cold heading machine is a device used to manufacture fasteners, especially suitable for producing bolts, nuts, nails, rivets and steel balls. It uses the cold heading process to sequentially complete the processes of cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and trimming on a dedicated cold heading machine to achieve continuous, multi-station and automated production

The main working principle of the four-station cold heading machine is to complete different processing steps in sequence through multiple stations. Each station has its specific function, such as cutting, heading, forming, etc. The machine adopts air clutch and inverter, which can realize multiple operation modes such as inching, single operation and continuous operation, ensuring mold safety and maximizing operation and debugging space. In addition, the four-station cold heading machine is usually equipped with advanced feeding system and clamping system to ensure accurate feeding and stable clamping.
