In our production process, we must pay attention to the mechanical performance and structure design of the induction quenching. Therefore, we should first understand the main purpose of the mechanical parts induced quenching, first know why we have to pay attention to the mechanical parts to quench, we can In-depth understanding of the mechanical properties and structural design of inductive quenching parts.
1. Improve the abrasion resistance induction quenching rental of the part surface is applied to the crank neck surface, and the purpose is to improve the wear resistance of the journal, where the crankshaft is used, the induction quenching makes the abrasion neck Greatly improve.
2. Improve the fatigue intensity of the part is further application to improve the fatigue strength of the quenching parts, such as the EQ1092 automobile half-axis, under + 3000n.m torque, the fatigue test is 2 million, still intact, and the original tuning process However, the half-axis fatigue life is less than 300,000; if it turns to the pallow head, the original process is 18 Grmnti steel infosing, and then the 45 steel induction is quenched, and the bending fatigue life of the parts is increased from 80,000 times to 2 million times. The above; the crankshaft round-sensitive quenching increases the fatigue strength of the crankshaft by 1 to the crankshaft; some product crankshaft fatigue strength reaches 700 MPa.
3. Reduce the distortion of the carburized gear due to long process time, the distortion after quenching; the gear sensing quench, especially the synchronous dual-frequency (SDF) gear quenching, short process time, small distortion, and increase the accuracy of the gear, and the noise reduction.
4. Energy saving, pumping, saving labor and environmental protection use parts such as low-quenching steel to make gears, and perform induction quenching. It is firstly the steel no-alloy element, saves material costs; induction heating is partial heating quenching, short time, therefore great energy saving; induction quenching can be automated online production, save labor; no oil, no harmful gas emissions, more protection surroundings.
5. Replace the deep penetration deep penetration is a process of long cycle and electricity consumption. In recent years, we have replaced deep infiltration in foreign countries in recent years, and it has achieved good results.
