过去我们在制作弯头(俗称虾米腰)、牛角弯、等径三通类的工件时,一直是沿用老的办法,即经过放样、制造样板、号料、手工气割、滚圆、组装等六道工序。这样不仅技术性强,新工人不易掌握,而且工序繁多质量也差,生产效率低。经过反复摸索制成了专门用于弯头等类工件的弯头放样切割机。弯头放样切割机具有结构简单、操作方便、容易掌握等优点,与旧工艺比较,可以省去放样、制造样板、号料等工序,并将手工气割改为半自动化,不但产品质量好,节约原材料,而且提高工效两倍。
In the past we used to make elbow (commonly known as shrimp waist), horns, such as three-way diameter of the workpiece, has been the use of the old way, that after the lofting, manufacture model, number, manual gas cutting, spheronization, assembly and other six processes . This is not only technically strong, not easy to grasp the new workers, but also the quality of many processes poor, low productivity. After repeated exploration made of a special elbow and other types of work piece elbow lofting cutting machine. Elbow lofting and cutting machine has the advantages of simple structure, convenient operation, easy to grasp, etc. Compared with the old process, it is possible to omit the procedures of setting out samples, manufacturing samples and materials and converting the manual gas cutting into semi-automatic, which not only has good product quality and saves Raw materials, but also improve work efficiency twice.
