METHOD AND DEVICE FOR MANUFACTURING A BLANK FOR A TOOL

摘要

The present invention relates to a method and a device for manufacturing a tool and a tool according to the method. The device shall be mounted to a machine for extrusion of a tool for chip removing machining. The device (20) comprises a housing (21), which is intended to be fastened to the machine for extrusion. The housing (21) has a through-going recess (24) through which a mixture shall be extruded in a feed direction (F). The recess (24) includes a restriction (27) in a nozzle (28) and a hole (30) in a die (29). The die (29) is rotatably journalled relative to the nozzle (28). A core (33) is firmly secured in the nozzle (28). The pins (35) are secured to the core. The pins (35) are provided axially distant from the rotatable die (29).
