Fuente: WIPO "circular economy" The invention relates to the technical field of hard alloy wire drawing, in particular to a hard alloy wire drawing die and method. The wire drawing die comprises a die body, a die core, a fixing assembly and a self-locking assembly, the die core is detachably connected with the die body, the fixing assembly is arranged on one side of the die body, and the self-locking assembly is arranged on one side of the die body; the wire drawing method comprises the following steps: placing the mold core in the mold body; the fixing assembly is controlled to clamp and fix the mold core; the wire is inserted into the mold core from the end, with the large diameter, of the mold core, the area, with the small diameter, in the mold core is adopted for compressing the wire, and the wire is compressed and stretched; when the mold core is installed, the mold core is firstly placed in the mold body, then the mold core is fixed by controlling the fixing assembly, meanwhile, the fixing assembly is locked through the self-locking assembly, connection between the mold core and the mold body is enhanced, when the mold core is disassembled, the mold core can be disassembled only by controlling the self-locking assembly and the fixing assembly, and the mold core is convenient to replace.
