Products Introduction

3 Die 6 Punch Cold Heading Machine is an advanced cold forming system equipped with three dies and six punches, specifically designed for manufacturing complex fasteners with high dimensional accuracy. It performs multiple sequential forming steps within a single cycle, making it ideal for producing intricate parts such as special bolts, long screws, and stepped shafts. The working principle involves feeding and cutting metal wire, then progressively shaping the part through coordinated punches and dies. This machine is widely used in automotive, aerospace, and precision hardware industries where performance, complexity, and production efficiency are critical.

Working Principles of 3 Die 6 Punch Cold Heading Machines

“3 Die” → The machine has three forming dies (stations). Each die progressively shapes the workpiece, allowing for multi-stage forming in a single cycle.

“6 Punch” → There are six punches distributed across the three dies, enabling multiple forming operations such as upsetting, trimming, piercing, or knurling at each stage.

Here are its basic working principles:

Wire Feeding and Cutting

The machine automatically feeds wire from a coil and cuts it to the required length.

First Die – Initial Forming

One or more punches perform the first stage of shaping, typically forming the head or preforming the workpiece.

Second Die – Intermediate Forming

Additional punches carry out further forming, such as creating diameter transitions, shaping the shank, or punching holes.

Third Die – Final Forming

The last set of punches completes the head shape, trims excess material, or adds final features.

Ejection and Collection

After forming, the finished part is automatically ejected, ready for the next process or packaging.
