They are divided into single-hole, double-hole, socket, hook, etc., and are divided into copper-plated silver, copper-plated zinc, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity. In order to adapt to different installation environments, traditional wiring terminals need to be bent at a certain angle, and the bending angle is usually within ninety degrees. The bending operation usually involves placing the terminal into a mold in a bending machine, and then using a punch to squeeze the terminal. However, in actual use, the bent terminal is easily stuck in the mold, which makes it inconvenient to lower and remove the terminal, and there are deficiencies in use. For this reason, we propose a terminal shaping and bending device. Summary of the invention
