在芯棒上拔长。锻造时,先芯棒插入冲好孔的坯料中,然后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,辽宁forging,再倒角滚圆,forging哪家好,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 on the mandrel. When forging,forging厂家, 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 h***e a slope of about 1:100.
自由锻造分手工自由锻和机器自由锻。手工自由锻生产效率低,劳动强度大,仅用于修配或简单、小型、小批锻件的生产。
Manual free forging is inefficient and labor intensive. It is only used for the production of repair or simple, ***all and ***all forgings.Free forging c***ists of manual free forging and machine free forging.
自由锻造的设备分为锻锤和液压机两大类。生产中使用的锻锤有空气锤和蒸汽-空气锤,有些厂还使用结构简单,***少的弹簧锤、夹板锤、杠杆锤和钢丝锤等。
The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The forging hammers used in production are air hammer and steam-air hammer. Some factories also use spring hammer, splint hammer, lever hammer and steel wire hammer with simple structure and low investment.
