Abstract (en)
[origin: CN107262632A] A coiling tool (11) for a spring coiling machine includes a tool support (15) and a replaceable coiling part (18). The coiling part is fixed to the tool support (15). The coiling part (18) includes a cylindrical pedestal (21) and a coiling body (22) positioned next to the pedestal in an axial direction. In a mounted state, the cylindrical pedestal (21) is arranged on a supporting face (16) configured in a front end region of the tool support (15). The pedestal (21) is pressed against, relative to the area of the front end region, a supporting step (17) that defines the supporting face (16) and extends in an arc manner. The coiling part (18) is prevented from being mounted rotatably and is fixed to the tool support (15) through a central fastener (19).
