Patent No. EP3225325 (titled "Coiling Tool For Spring Coiling Machine") was filed by Wafios on Feb 15, 2017. The application was issued on Mar 9, 2022.
A coiling tool for a spring coiling machine comprises a tool holder (15) and an interchangeable coiling insert (18). The insert features a cylindrical base (21) and an axially adjacent coiling body (22, 28). In the assembled state, the cylindrical base sits on a bearing surface (16) at the tool holder's front end region and bears against a circular segment supporting step (17) delimiting said surface. The insert is rotationally fixed and secured to the tool holder via a central clamping means (19). To ensure precise positioning, a detent (24) acting in the circumferential direction of the cylindrical base is attached to the side facing the bearing surface, engaging a corresponding counterpart latching element (26) on the tool holder.
