和每臺(tái)車輛一樣，鑄鋼件樣子及數(shù)量也各不相同。

依據(jù)開(kāi)啟式自由鍛時(shí)，鑄鋼件主中心線與別的兩方位規(guī)格的關(guān)聯(lián)，可將鑄鋼件分成兩類七種，即短軸類鑄鋼件和短軸類鑄鋼件。閉試自由鍛時(shí)，按金屬材料流動(dòng)性分壓擠和鐓擠，即第三類別是壓擠類鑄鋼件，此外也有頂鐓(鐓鍛)類鑄鋼件，頂鐓又分成兩類，即構(gòu)件頂鐓件和管材頂鐓件，各種鑄鋼件均有自身的煅造特性。煅造時(shí)鍛擊方位與主中心線平行面，金屬材料沿長(zhǎng)、寬、高三個(gè)方位與此同時(shí)形變流動(dòng)性，歸屬于容積形變

2.短軸類鑄鋼件以及煅造特性

短軸類鑄鋼件主中心線方位的規(guī)格遠(yuǎn)高于別的兩方位規(guī)格，其又分成直長(zhǎng)中心線類、彎折中心線類、幼葉類、叉類，例如中間軸、前軸、發(fā)動(dòng)機(jī)曲軸、離合拔叉、分離出來(lái)叉、曲軸、臥鍛轉(zhuǎn)向拉桿等

煅造時(shí)鍛擊方位與主中心線豎直，形變金屬材料沿長(zhǎng)短(主中心線)方位的形變流動(dòng)性較少，可以類似當(dāng)做是平面圖形變.

Like every car, the shape and number of forgings vary.

According to the relationship between the main axis of the forging and the dimensions in the other two directions during the open die forging, the forgings can be divided into two categories and seven types, that is, short-axis forgings and long-axis forgings. During closed die forging, extrusion and upsetting are divided according to metal flow, that is, the third category is extrusion type forgings, and there are also top-forging (upsetting) types of forgings. Top-up is divided into two categories, namely rods. Forging pieces and pipe pieces, various types of forgings have their own forging characteristics. When forging, the forging direction is parallel to the main axis. The metal deforms and flows simultaneously in three directions: length, width and height, which is a volume deformation.

2. Long shaft forgings and forging characteristics

The dimensions of the long axis forgings in the main axis direction are much larger than those in the other two directions. They are further divided into straight and long axis types, curved axis types, branch and bud types, and fork types, such as intermediate shafts, front shafts, crankshafts, clutch forks, and separation. Forks, connecting rods, horizontal forged knuckles, etc.

When forging, the forging direction is perpendicular to the main axis, and the deformation flow of the deformed metal along the length (main axis) is less, which can be regarded as a plane deformation.
