鍛造是一種利用鍛壓機(jī)械對(duì)金屬坯料施加壓力，使其產(chǎn)生塑性變形以獲得具有一定機(jī)械性能、一定形狀和尺寸鍛件的加工方法，鍛壓（鍛造與沖壓）的兩大組成部分之一。

Forging is a kind of forging process that uses pressure forming machinery to exert pressure on metal billet and make it produce plastic deformation to obtain certain processing methods of forging, which has certain mechanical properties, shape and size, and is one of the two components of forging, forging and stamping.

鍛件是金屬被施加壓力，通過(guò)塑性變形塑造要求的形狀或合適的壓縮力的物件。這種力量典型的通過(guò)使用鐵錘或壓力來(lái)實(shí)現(xiàn)。鍛件過(guò)程建造了精致的顆粒結(jié)構(gòu)，并改進(jìn)了金屬的物理屬性。

A forged piece is an object that is applied to the metal by pressure to shape the required shape or the appropriate compression force by plastic deformation. This force is typically achieved by using a hammer or pressure. The process of forging has built a fine particle structure and improved the physical properties of the metal.

在芯棒上拔長(zhǎng)。鍛造時(shí)，先芯棒插入沖好孔的坯料中，然后當(dāng)作實(shí)心坯料進(jìn)行拔長(zhǎng)。拔長(zhǎng)時(shí)，一般不是一次拔成，先將坯料拔成六角形，鍛到所需長(zhǎng)度后，再倒角滾圓，取出芯棒。為便于取出芯棒，芯棒 的工作部分應(yīng)有1：100 左右的斜度。

Pull on the mandrel. When forging, insert the mandrel into the billet of the hole and then pull it out as a solid billet. When drawing, it is not usually drawn at one time. First, the blank is drawn into a hexagonal shape, forged to the required length, then chamfered and rounded, and the mandrel is removed. To facilitate the removal of the mandrel, the working part of the mandrel should have a slope of about 1:100.
