Quality of Tricone Bit 

 

      Tricone bit must take into account the quality of the material of the capital and the strength of the set period, the mold material selection is necessary to meet customers' production of wind-induced volume requirements.

While still under the mold tricone bit example, the use of things essentials, processing speed, tension, etc. due to failure of the situation has always been selection. For example: Die tension failure situation is edge wear, we must select high hardness, good wear resistance material; stamping die tension suffered cyclic loading, easy to cause appearance of fatigue crack, causing the surface peeling, then to choose looks good toughness material; drawing die should choose particularly low coefficient of friction of the material; casting mold due to cyclic thermal stress, it should choose a strong thermal fatigue of the material; deal with injection mold, when the three-cone drill, the mold material optional pre-hardened quenched and tempered steel, when the plastic parts for the high-quality finish, transparent material, the optional corrosion resistant stainless steel, when large quantities of goods, you can choose quenched and tempered steels. Also it is necessary to consider the acceptance and other parts of the mold material smaller affinity to intensify anti-sticking mold parts wear, thus affecting the quality of the mold.
