随着电动机的发明，十九世纪末出现了以电为动力的机械压力机和空气锤，并获得迅速发展。第二次世界大战以来，七十五万千牛的模锻水压机、一千五百千焦的对六万千牛的板料冲压压力机、十六万千牛的热模锻压力机等重型锻压机械，和一些自动冷镦机相继问世，形成了门类齐全的锻造机械体系。
With the invention of motor， the mechanical press and air hammerpowered by electricity appeared at the end of nineteenth Century，and developed rapidly. Since the Second World War， the forgingwater press， one thousand and five hundred thousand char，圣霖国际锻造，the punching press of Liu Wanqian cattle， the hot forging press ofsixteen thousand thousand cattle， and some automatic cold headingmachines have come out in succession， forming a complete system offorging machinery.
在芯棒上拔长。锻造时，先芯棒插入冲好孔的坯料中，当作实心坯料进行拔长。拔长时，一般不是一次拔成，先将坯料拔成六角形，锻到所需长度后，圣霖国际锻造价格，再倒角滚圆，取出芯棒。为便于取出芯棒，芯棒的工作部分应有1：100 左右的斜度。
Pull onthe mandrel. When forging，圣霖国际锻造采购， insert the mandrel into thebillet of the hole and then pull it out as a solid billet. Whendrawing， it is not usually drawn at one time. First， the blank isdrawn into a hexagonal shape，圣霖国际锻造厂， forged to the requiredlength， then chamfered and rounded， and the mandrel is removed. Tofacilitate the removal of the mandrel， the working part of themandrel should have a slope of about 1:100.
锻造设备种类很多，按照工作部分运行方式不同，锻造设备可分为直线往复运动和相对旋转运动两大类。直线往复锻造设备1、动载撞击的锻造设备2、动静载联合的锻造设备3，高效能冲击的锻造设备。
There are many kinds of forging equipment. According to thedifferent operation modes of the working part， the forgingequipment can be divided into two categories: straightreciprocating motion and relative rotation motion.
Linear reciprocating forging equipment
1， forging equipment with dynamic load impact
2， forging equipment combined with static and static load
3， high efficiency impacting forging equipment
