工业上广泛采用各种薄壁管材(壁厚为2.5mm以下)做零件。通常管材的切断是采用手锯、锯床或砂轮机切断。采用这些方法只能沿直线方向切断。呈曲线形的切断需要用气割或锉刀修磨,生产效率低、质量也难以保证。应用管材剪切技术可以保证质量,大大地提高生产效率,对大量采用管材做零件的工业部门(如汽车、拖拉机、自行车等)更有其经济和技术上的优越性。管材的剪断或切口是用剪切模来实现的。剪断模的凸模形状 Widely used in the industry a variety of thin-walled tubes (wall thickness of 2.5mm below) to do the parts. Usually pipe cutting is to use hand saws, sawing machine or grinder off. Using these methods can only be cut along a straight line. Curved cutting need to use gas cutting or file grinding, production efficiency is low, the quality is difficult to guarantee. The application of pipe cutting technology can ensure the quality and greatly improve the production efficiency. It is more economical and technical superior to the industrial departments (such as cars, tractors, bicycles, etc.) that make pipe fittings as parts. Pipe cutting or incision is to use shear mode to achieve. Cut the punch punch shape
