Tungsten carbide material for high-performance wedge welding chopper and production method of tungsten carbide material
The invention relates to a tungsten carbide material for a high-performance wedge welding chopper, which comprises the following components in percentage by weight: 66 to 84.5 percent of WC, 10 to 20 percent of TiC, 2 to 10 percent of Co, 2 to 10 percent of Ni, 0.2 to 0.4 percent of Cr2C3, 0.2 to 0.4 percent of VC, 0.5 to 5 percent of MoC and 0.5 to 10 percent of K. K is at least one of tantalum carbide, hafnium carbide, niobium carbide, rhenium carbide, tantalum niobium carbide solid solution and tungsten titanium carbide solid solution; according to the production method of the tungsten carbide material, the vertical lead hole near-net mold pressing technology is adopted, the ultrasonic bonding efficiency and the bonding abrasion performance of the tungsten carbide wedge bonding chopper are improved, the method is further adapted to the hot-pressing ultrasonic working condition of wedge bonding, the service life of the wedge bonding chopper is greatly prolonged, and the tungsten carbide material can be used for manufacturing the wedge bonding chopper. A vertical lead hole near-net mold pressing technology is developed, 0.1-1.0 mm inner hole type tungsten carbide wedge bonding chopper blank production is achieved, part of precision machining procedures are reduced, the production process is shortened, and the wedge bonding chopper production cost is greatly reduced.
一种用于高性能楔焊劈刀的碳化钨材料，碳化钨材料的成分以重量百分比计，由以下组分组成：WC 66‑84.5%、TiC 10‑20%、Co 2‑10%、Ni 2‑10%、Cr2C3 0.2‑0.4%、VC 0.2‑0.4%、MoC 0.5‑5%、K 0.5‑10%，所述K为钽的碳化物、铪的碳化物、铌的碳化物、铼的碳化物、碳化钽铌固溶体、碳化钨钛固溶体中的至少一种；该碳化钨材料生产方法是采用垂直引线孔近净模压技术，提升了碳化钨楔焊劈刀的超声键合效率和键合磨损性能，进一步适配于楔焊键合的热压超声工况，大幅提升了楔焊劈刀的使用寿命，并对该碳化钨材料，开发出垂直引线孔近净模压技术，实现了0.1‑1.0mm内孔式碳化钨楔焊劈刀坯料生产，减少了部分精密加工工序，缩短了生产流程，大幅降低楔焊劈刀生产成本。
