Product Introduction

Our multi-station cold heading machine is a fully automatic high-efficiency cold forging equipment, specially developed for large-scale production of standard and non-standard fasteners as well as complex cold-formed parts. It integrates automatic wire feeding, straightening, cutting, multi-station upsetting and finished product discharging into one continuous production process, which significantly improves production efficiency and forming precision compared with single-station cold heading equipment.

This machine series offers 4-station, 5-station and 6-station options, suitable for manufacturing hex bolts, carriage bolts, flange bolts, hex nuts, blind rivets, step pins, self-tapping screws and various special-shaped metal parts. It is an ideal core equipment for fastener manufacturing factories and metal forming enterprises.

Key Features & Advantages

1. Rigid & Durable Machine Body The whole machine bed adopts one-piece high-grade cast iron structure with excellent shock absorption and deformation resistance. All core transmission components are made of high-quality alloy steel, processed by high-precision CNC machine tools and treated with vacuum heat treatment, ensuring long service life and stable long-term operation.
2. High Precision Forming With precision crankshaft transmission system and die positioning structure, the forming tolerance of finished products can be controlled within ±0.02mm. The multi-station progressive forming design effectively reduces internal stress of workpieces, and guarantees consistent product quality and high material utilization rate.
3. Intelligent & Easy Operation Equipped with a well-known brand PLC control system and color touch screen HMI, the machine supports intuitive parameter setting, real-time production data monitoring, automatic fault alarm and diagnosis. The variable frequency feeding system realizes stepless speed regulation, which can be flexibly adjusted according to different materials and product processes.
4. Comprehensive Safety Protection Built-in multiple safety mechanisms including overload protection device, material shortage alarm, safety door interlock and emergency stop button, which fully protect the safety of operators and avoid equipment damage caused by abnormal operation. The automatic centralized lubrication system delivers lubricant to each friction point accurately, reducing wear and daily maintenance cost.

Application Fields

This series of cold heading machines can process carbon steel, alloy steel, stainless steel, copper, aluminum and other common metal wires. Its finished products are widely used in automotive manufacturing, construction engineering, electronic appliances, aerospace, railway transportation, furniture hardware and other industries.
