Manufacturing method of wear-resistant threaded block suitable for flaw detection wear-resistant block

The invention discloses a manufacturing method of a wear-resistant threaded block suitable for a flaw detection wear-resistant block. The wear-resistant threaded block comprises a contact part and a threaded part, one side surface of the contact part is inclined at an angle of 20-35 degrees relative to the direction of the thread part; and a transition surface is arranged at the junction of one side surface adjacent to the inclined surface and the top surface. Alloy with the Rockwell hardness larger than 90 is machined, the integrated wear-resistant threaded block made of the super-hard material is directly formed, the wear resistance of the whole wear-resistant block is improved, the number of times of thread replacement is reduced, and the wear resistance of the wear-resistant block is matched with that of the wear-resistant threaded block. 本发明公开了一种适用于探伤耐磨块的耐磨螺纹块制造方法，包括：接触部和螺纹部；所述接触部的一侧面相对于螺纹部方向呈20-35°倾斜；与倾斜面相邻的一侧面与顶面交界处设有过渡面。本申请对洛氏硬度大于90的合金进行加工，直接形成一个一体化的超硬质材料耐磨螺纹块，增加了整体耐磨块的耐磨性，减少更换螺纹的次数，使得耐磨块与耐磨螺纹块的耐磨性相匹配
