在鍛錘上进行自由鍛造的时候,拔長(伸展)和甩圓的工作特別多。坯料在平砧上拔長以后,为了使它的形狀規矩、尺寸精确,往往要在甩子中甩圓。一般工厂使用的甩子,結構比較陈旧,用起来很笨很吃力。下面介紹的兩种机械化甩子,是由一位苏联鍛工同志設計出来的。这种甩子裝在鍛錘上使用非常方便,可以大大地减輕咱們的劳动强度。 圖1表示甩圓头的机械化甩子,圖2表示甩圓杆的甩子,用它們来鍛制 In the forging hammer free forging time, pull (stretch) and rejection of the round of work in particular. After the billet draws on a flat anvil, in order to make it the shape of the rules, the size is accurate, often rejection of rejection in the circle. General factory use of rejection son, the older structure, it is stupid with very difficult. The two types of mechanized nudges described below were designed by a Soviet forge comrade. This rejection is mounted on the forging hammer is very easy to use, can greatly reduce our labor intensity. Fig. 1 shows a mechanized rejection of a round head, Fig. 2 shows a rejection of a round bar, forging with them
