锻件加工通过塑性变形塑造需求的形状或适宜的压缩力的物件。通过运用铁锤或压力来完成。金属通过铸造加工后能改进其安排构造和力学性能，铸造加工能确保金属纤维安排的连续性，使锻件的纤维安排与锻件外形保持共同，金属流线完整，可确保零件具有良好的力学性能与长的运用寿命。

　　An object used to shape a desired shape or a suitable compressive force by plastic deformation. Finish by using a hammer or pressure. Metal by casting processing can improve its arrangement structure and mechanical properties of casting processing can ensure the continuity of the metal fiber arrangement, the fiber arrangement and shape forging forging Co, metal streamline integrity, can ensure that the parts have good mechanical properties and long service life.

　　热模锻的工艺流程为：锻坯下料;锻坯加热;辊锻备坯;模锻成形;切边;冲孔;纠正;中心查验，查验锻件的尺度和外表缺陷;锻件热处理，用以消除铸造应力，改进金属切削性能;整理，主要是去掉外表氧化皮;纠正;查看，锻件要通过外观和硬度查看，还要通过化学成分剖析、机械性能、剩余应力等查验和无损探伤。　铸造用料主要是各种成分的碳素钢和合金钢，其次是铝、镁、铜、钛等及其合金。资料的初始状况有棒料、铸锭、金属粉末和液态金属。铸造可分为自由锻、镦粗、挤压、模锻、闭式模锻、闭式镦锻。

　　The process of hot die forging for forging billet heating; forging; forging billet preparation; forging; trimming; punching; correction; Center for inspection, inspection scale and appearance defects of forging; forging heat treatment to eliminate casting stress, improve the cutting performance of metal finishing, mainly to remove the appearance; oxide skin; correct; see, to see through the appearance and hardness of forgings, but also through chemical composition analysis, mechanical properties, residual stress and NDT inspection etc.. The casting materials are mainly carbon steel and alloy steel of various components, followed by aluminum, magnesium, copper, titanium and their alloys. The initial conditions of the data are rod, ingot, metal powder and liquid metal. Casting can be divided into free forging, upsetting, extrusion, die forging, closed die forging, closed upsetting.

　　锻模的运动方法，铸造又可分为摆辗、摆旋锻、辊锻、楔横轧、辗环和斜轧等方法。摆辗、摆旋锻和辗 环也可用精锻加工。锻件加工需要每片都是共同的，没有任何多孔性、多余空间、内含物或其他的瑕疵。锻件的长处有可扩展的长度、可收缩的横截面;可收缩的长度、可扩展的横截面;可改动的长度、可改动的横截面。柴油机所用的锻件有汽缸盖、主轴颈、曲轴端法兰输出端轴、连杆、活塞杆、活塞头、十字头销轴、曲轴传动齿轮、齿圈、中心齿轮和染油泵体等十余种。

　　The movement method of forging die can be divided into swing rolling, swing forging, roll forging, cross wedge rolling, ring rolling and cross rolling. Rotary forging, swing forging and ring rolling can also be made by precision forging. The forging process requires that each piece is common without any porosity, excess space, inclusions, or other defects. The advantages of a forging include an expandable length, a contracted cross section, a contracted length, an expandable cross section, an adjustable length, and a variable cross section. The diesel engine cylinder cover, shaft forgings, crankshaft end flange output shaft, connecting rod, piston rod, piston head, crosshead pin shaft, crankshaft gear, gear, gear center and more than ten kinds of dye pump body.
