坡口的一次切割成形法,是一种先进的切割工艺。它具有加工成本低、生产效率高、适用范围广等优点。目前,在国外已有定型的切割设备,并广泛用于生产,如苏联的C—4型与ⅡC—2型切割机以及日本产的PC—10型与PC—11型切割机均属此类。近两年来,我厂通过对江南造船厂生产的半自动切割机的改装,在坡口的一次成型工艺方面进行了大量的试验工作,并取得了较大收获。设备的改装及试验条件在江南造船厂生产的半自动切割机上,做了如下改装:①设计并安装一个能固定三只割
Groove a cut forming method is an advanced cutting process. It has the advantages of low processing cost, high production efficiency and wide application. At present, there are stereotypical cutting equipment abroad, and is widely used in the production, such as the Soviet C-4 and Ⅱ C-2 cutting machine and the Japanese-made PC-10 and PC-11 cutting machine are such . In the past two years, our factory has carried out a large number of tests on a molding process of bevel through the modification of semi-automatic cutting machine produced by Jiangnan Shipyard and achieved great gains. Equipment modification and test conditions In Jiangnan Shipyard’s semi-automatic cutting machine, made the following modifications: ① design and installation of a fixed three cut
