二十世纪60年代以后,锻造机械改变了从19世纪开始的,向重型和大型方向发展的趋势,转而向高速、***、自动、精密、专用、多品种生产等方向发展。
After 60s twentieth Century, forging machinery changed the trend from nineteenth Century to he***y and large direction, and turned to high speed, high efficiency,圣霖国际锻造, automatic, precision, special, multi variety production.
自由锻造是利用冲击力或压力使金属在上下砧面间各个方向自由变形,不受任何限制而获得所需形状及尺寸和一定机械性能的锻件的一种加工方法,简称自由锻。
Free forging is a processing method of forging parts,圣霖国际锻造厂, which can make metal in all directi*** of the anvil between the upper and lower anvil,圣霖国际锻造采购, and obtain the required shape and size and certain mechanical properties by the impact force or pressure, and the free forging is called free forging.
基本工序:自由锻造时,圣霖国际锻造生产,锻件的形状是通过一些基本变形工序将坯料逐步锻成的。自由锻造的基本工序有镦粗、拔长、冲孔、弯曲和切断等。
The basic process is: free forging, the shape of forging is gradually formed by some basic deformation processes. The basic process of free forging is upsetting, drawing, punching, bending and cutting.
