Secondly, some devices require frequent mold replacement, but the installation or replacement of part molds will become difficult. Replacing and installing new models of part molds will become more time-consuming and complicated, and it is difficult to ensure a firm connection between the part mold and the bending table, which may lead to a loose connection and affect the forming quality. Finally, some devices make the connection process more complicated and difficult, and it is difficult to ensure the accuracy and reliability of the connection operation. Utility Model Content
