The working principle of the cold heading machine is that at room temperature, the metal material is deformed in the mold by applying an impact force, so that the parts with the required shape and size can be obtained.

The specific working process is as follows:

1. Material feeding: feeding the metal wire into a cold heading machine.

2. Impact forming: the punch exerts an impact force on the material to make it form in the mold.

3. Mold function: The mold determines the shape and size of the parts.

4. Continuous processing: high-efficiency continuous production can be realized.

The characteristics of the working principle of cold heading machine include:

1. Efficient production: fast and suitable for mass production.

2. High accuracy: ensure the dimensional accuracy and shape accuracy of parts.

3. Material saving: high material utilization rate.

4. Improve performance: improve the mechanical properties of the parts.

When using the cold heading machine, you should pay attention to the following points:

1. Select appropriate materials: according to the requirements of parts.

2. Mold design and maintenance: ensure the quality and stability of the mold.

3. Equipment debugging: reasonably set process parameters.

4. Safe operation: prevent accidents.

5. Quality inspection: quality inspection of the parts produced.
