Henan Sifangda Superhard Materials Co., Ltd. (hereinafter referred to as “the companyâ€) recently obtained three utility model patent certificates issued by the State Intellectual Property Office. The details are as follows: No. Patent Name Patent No. Patentee Patent Type Authorization Day 1 Clamping Tool for EDM Chamfering ZL201120315345.8 Sifangda Utility Model April 18, 2012 2 A polycrystalline diamond enhanced pick ZL201120318686.0 Sifangda Utility Model April 18, 2012 3 A super hard material DTH drill bit ZL201120314953.7 Sifangda utility model April 18, 2012 "Clamping tool for EDM chamfering" utility model can The EDM machining chamfer replaces the machining chamfering, reduces the processing cost, ensures the chamfering precision of the super-hard material, avoids the edge and the gap, and ensures the service life of the material workpiece. "A polycrystalline diamond reinforced pick" The utility model is to apply the high wear resistance of the polycrystalline diamond composite sheet to the pick of the roadheader, accelerate the tunneling efficiency, improve the service life of the cutting head, and reduce the service life. Cost, which in turn reduces construction costs and shortens construction time. “A super-hard material DTH drill bit†The utility model not only incorporates the high wear resistance of the super-hard material column head, but also has the impact resistance, service life and rock drilling efficiency of the traditional hard metal down-the-hole drill bit. It is much higher than the traditional cemented carbide drill bit. The acquisition of the above patents will not have a major impact on the company's production and operation, but it will help protect the company's intellectual property rights, form a continuous innovation mechanism, and enhance the company's core competitiveness.
