Abstract
本发明公开了一种发动机平衡轴及其锻造方法,其化学成分以重量计算,构成为:0.47-0.55%碳、0.17-0.37%硅、0.50-0.80%锰、0.01-0.03%钒、0.001-0.002%铌、磷不大于0.035%、硫不大于0.035%、铜不大于0.17%、余量为铁。其锻造方法是:首先将平衡轴采用的按上述比例制成的碳素钢材料进行截料,再对该截料进行加热及制坯、成型工序制成平衡轴坯料;然后切除平衡轴坯料的毛边及坯料两端头的拔模斜度,将切边后的平衡轴坯料通过输送带输送使该坯料自然冷却而再进行热处理工艺、热校正、表面处理工序而制得发动机平衡轴锻件。此构成和制造方法显著改善了钢的金属组织结构,提高了锻件的机械强度、冲击韧性,且节约了能源。从而提高了产品的质量,延长了产品的使用寿命。The invention discloses an engine balance shaft and a forging method thereof. Its chemical composition is calculated by weight, and consists of: 0.47-0.55% carbon, 0.17-0.37% silicon, 0.50-0.80% manganese, 0.01-0.03% vanadium, 0.001- 0.002% niobium, phosphorus not more than 0.035%, sulfur not more than 0.035%, copper not more than 0.17%, and the balance being iron. The forging method is as follows: first cut off the carbon steel material used for the balance shaft according to the above ratio, then heat the cut material, make a billet, and form a blank of the balance shaft; then cut off the balance shaft blank The draft angle of the raw edge and the two ends of the billet, the trimmed balance shaft billet is transported by the conveyor belt, the billet is naturally cooled, and then the heat treatment process, heat correction, and surface treatment processes are performed to obtain the engine balance shaft forging. The composition and manufacturing method significantly improve the metal structure of the steel, increase the mechanical strength and impact toughness of the forging, and save energy. Thereby improving the quality of the product and prolonging the service life of the product.
