在四冲程内燃机的运转过程中,汽缸内燃料燃烧爆发产生的能量,是通过连杆传递给曲轴带动飞轮而做功的。连杆在每个冲程中都受到交变的冲击、拉伸、扭转等各种应力的作用。因而,一旦在运转过程中发生断裂,就会酿成重大事故。为了确保连杆的产品质量,历来都是采用经过严格检查的优质高强度钢材以及生产成本高昂的锻造工艺进行制造。由于在内燃机行业中,有条件从事模锻生产的单位为数不多,再加
During the operation of the four-stroke internal combustion engine, the energy generated by the fuel combustion in the cylinder is produced by connecting the crankshaft to the flywheel through the connecting rod. Connecting rod in each stroke are subject to alternating impact, stretching, torsion and other stress. Therefore, once the operation in the process of fracture, it will lead to major accidents. In order to ensure the quality of the connecting rod, it has traditionally been manufactured using a rigorous inspection of high-quality, high-strength steels and a high-cost forging process. As in the internal combustion engine industry, the conditions for the production of die forging a few units, plus
