一般化工设备和容器中有許多小型封头(頂盖或底盖),如图1所示。在自由鍛錘上采用如图2所示的模具热压这种封头,效果很好。这种方法不仅能比用手工鍛打的方法,提高生产率5倍以上,而且改善了劳动条作,提高了封头質量。現在把模具結构和操作方法介紹如下: 模具結构如图2所示,由五个主要零件組成。在压制时,把毛坯加热到1100℃左右,放在模具的下 There are many small heads (top or bottom) in a typical chemical plant and container, as shown in Figure 1. In the free forging hammer as shown in Figure 2, the mold pressing the head, the effect is very good. This method can not only improve the productivity by more than 5 times compared with the method of hand forging, but also improve the workmanship and improve the quality of the head. Now the mold structure and method of operation are described below: Mold structure shown in Figure 2, consists of five major components. In pressing, the rough heating to 1100 ℃, on the mold
