Description

Technical Field

[0001] The utility model relates to the technical field of cold drawing machine material collection, in particular to a dividing type cold drawing machine calibration mechanism. Background Art

[0002] Hafnium wire is obtained by drawing metal hafnium. In nature, hafnium often coexists with zirconium. All zircon-containing minerals contain hafnium. Hafnium and zirconium are isomorphous. Hafnium is mainly found in zircon. The amount of HfO2 in zircon used in industry is 0.5-2%. The HfO2 content of beryllium zircon in secondary zircon ore can be as high as 15%. There is also a metamorphic zircon, qubilicate, which contains more than 5% HfO2. The reserves of the latter two minerals are small and have not yet been used in industry. Hafnium is mainly recovered in the process of zircon production. Cold drawing machines are required for drawing hafnium wire.

[0003] In the prior art, after the hafnium wire is drawn, the cold drawing machine needs to wind the hafnium wire on the surface of the receiving roller. However, the position of the receiving roller is fixed, which causes the hafnium wire to be wound only on one place on the surface of the receiving roller and cannot evenly cover the surface of the receiving roller, making it inconvenient to finally receive the wire.
