Abstract

PURPOSE:To form end hooks of a coil spring by simultaneously operating a forming tool and feeding a spring wire with a simple mechanism. CONSTITUTION:A wire (W) is fed by rollers 21 through a guide quill 20. A cam 3 pushes a slider 11 through a cam roller 7, a universal joint 8 attached on the end of an swing lever 5, a connecting rod 9 and a universal joint 10 against a spring 14. A forming tool 17 attached to the slider 11 by means of a holder base 19 and a tool holder 18 is pushed before the guide quill 20 forming the wire (W) into coils.
