[0003] In the process of bending the two ends of the copper strip, a copper strip forming die is needed to support the lower part of the copper strip bending part to ensure that the copper strip can be bent into the required curvature; since the copper strip forming die is a follow-up structure rather than an active structure, after each copper strip is formed, the forming die needs to be manually reset; this is time-consuming and labor-intensive, and reduces the production efficiency of the copper strip;
