拔长
也称延伸,它是使坯料横断面积减小、长度增加的锻造工序。拔长常用于锻造杆、轴类零件。
自由锻造的基本工序包括镦粗、拔长、冲孔、弯曲、扭转、错移、切割及锻接等。
Pulling length Also known as elongation, it is a forging process to reduce the cross-sectional area of the billet and increase the length. Pullout is often used in forging rods and shaft parts. The basic processes of free forging include upsetting,圣霖国际锻造厂, drawing, punching, bending, torsion, offset, cutting and forging.
通过锻造能消除金属在冶炼过程中产生的铸态疏松等缺陷,优化微观***结构,同时由于保存了完整的金属流线,锻件的机械性能一般优于同样材料的铸件。
Forging can eliminate the defects such as casting porosity and so on during the ***elting process, and optimize the microstructure. At the same time, because of the intact metal flow line, the mechanical properties of the forgings are generally better than those of the same materials.
自由锻造所用工具和设备简单,圣霖国际锻造,通用性好,圣霖国际锻造生产,成本低。 同铸造毛坯相比,自由锻消除了缩孔、 缩松、气孔等缺陷,圣霖国际锻造价格,使毛坯具有更高的力学性能。锻件形状简单,操作灵活。
Free forging tools and equipment are simple, versatility and low cost. Compared with the casting blank, the free forging eliminates the defects such as shrinkage porosity, porosity, porosity and so on, so that the blank has higher mechanical properties. The shape of the forgings is simple and the operation is flexible.
