The working principle of hot forging die is as follows:

1. Blank punching: the metal coil to be forged is introduced into a punching machine through a customized servo feeder, and the blank with sharp corners at two ends is punched out.

2. High-temperature heating: the blank is clamped into high frequency furnace with pliers and heated to burn red.

3. Put into the mold: clamp the red-hot workpiece into the guide chain at the front end of the mold with pliers.

4. Hot forging: the heated blank is continuously forged on three faces in the die, and then braked and pushed out of the die after bending.

5. cooling: after the forging process is completed, the product is completely cooled and taken away.

The characteristics of its working principle include:

1. Using the plastic deformation of metal: At high temperature, metal has good plasticity, which is convenient for deformation processing.

2. Impact force: plastic deformation and shape change of metal are realized by applying high pressure.

3. The guide plate with chain structure leads the semi-finished product into the next process step by step until the finished product is obtained.

In practical application, we should pay attention to the following points:

1. Select appropriate mold materials to withstand high temperature and high pressure.

2. Control the heating temperature and forging speed to ensure good forging quality.

3. Maintain and overhaul the mould regularly to ensure its accuracy and service life.

4. Carry out quality inspection on forgings, which meets the technical requirements.
