[0002] The track core is also called the track tooth, which is a basic part of the rubber track. The existing track core is generally processed by forging. After the processing is completed, some waste will remain on the outside of the core.

[0003] However, due to the special structure of the track core, the cavity is often difficult to fill during forging, and there are defects such as missing corners. If more materials are used, materials will be wasted. Therefore, this scheme proposes a short-process precision forming device for the core to solve the above-mentioned technical problems.
