Abstract

The present invention relates to a method for forming a reinforcement bar coupler and a mold thereof. The forming method comprises three steps, of which step one is pre-forming of a small-sized blank, step two is forging operation wherein the small-sized blank is put in a mold of the forging operation for proceeding with forging operation so that each blank is formed with a joint bore, and step three is tapping operation, wherein the joint bore of the blank is tapped to complete the formation of the reinforcement bar coupler. In addition, the forming mold of the present invention comprises a plurality of dies associated with respective forging processes and also comprises a plurality of punches associated with respectively forging processes. With such an arrangement, forging can be used in a non-material-wasting manner and mass and efficient production of reinforcement bar coupler can be realized. Also, internal structure of the reinforcement bar coupler can be enhanced to increase the overall strength of the reinforcement bar coupler.
