The first circular cutter body 11 and the second circular cutter body 12 are arranged at intervals to flatten the surface of the cemented carbide strip 1 through the pressure between the first circular cutter body 11 and the second circular cutter body 12. In addition, in this embodiment, the heating element 2 is arranged on the first circular cutter body and / or the second circular cutter body to heat the cemented carbide strip 1 and change the hardness of the alloy. On the one hand, it can reduce the wear of the cemented carbide strip 1, and on the other hand, it can make the cut edge of the cemented carbide strip 1 smoother. The embodiment of the utility model provides a cemented carbide strip strip assembly, which heats the cemented carbide strip 1 by arranging a heating element 2 thereon, thereby adjusting the hardness of the cemented carbide strip 1, thereby solving the technical problem of low solder yield caused by the hard and catalytic characteristics of the alloy solder itself in the prior art.
