低塑性拔长时,应注意选择合适的送进比,送进比太小时,变形集中在上下部,forging生产厂家,中心都锻不透,并沿轴向产生拉锻造应关于锻件的一些基本知识力,导致内部横向裂纹产生。在镦粗时,常用软衬垫镦粗或叠镦(用于锻薄饼形零件),以改善变形的不均匀性,防止产生表面裂纹。
When low plasticity is pulled out, attention should be paid to selecting suitable delivery ratio, sending too much time, deformation on the upper and lower parts, and the center can not be built,通化forging, and forging along the axial direction should be related to some basic knowledge of forging, resulting in the occurrence of internal transverse cracks. In the upsetting, commonly used soft liner (for upsetting or folding upsetting forging thin pancake, uneven parts) to improve the deformation, prevent the generation of cracks on the surface.





锻造设备是指在锻造加工中用于成形和分离的机械设备。锻造设备包括成形用的锻锤、机械压力机、液压机、螺旋压力机和平锻机,以及锻造操作机、开卷机、矫正机、剪切机、等辅助设备。
Forging equipment is the mechanical equipment for forming and separating in forging. Forging equipment includes forging hammer, mechanical press, hydraulic press, screw press, forging machine, forging machine, coiler,forging谁家好, straightening machine, shearing machine, and other auxiliary equipment.
在锻造时,金属的脆性杂质被打碎 ,顺着金属主要伸长方向呈碎粒状或链状分布;塑性杂质随着金属变形沿主要伸长方向呈带状分布 ,forging报价, 这样热锻后的金属***就具有一定的方向性。
When forging, the brittle metal impurities to be broken down, the main direction of elongation is like particles of metal or plastic chain distribution; impurities with metal deformation distributed along the main direction of elongation, so after hot forging metal organization has certain direction.
