在管子表面进行波纹成型的工艺可以代替熔焊、钎焊和旋压加工,从而使工艺过程大大简化。管子波纹成型的方法介绍如下:1.较短零件可用图1模具成型。如管子直径在8毫米以上,可在冲床上完成;如管子直径在8毫米以下,可用一般手扳压力机或加压设备。 The corrugated process on the tube surface can replace the welding, brazing and spinning processes, which greatly simplifies the process. Pipe corrugated method is described below: 1. Short parts available Figure 1 mold forming. If the pipe diameter of 8 mm or more, can be done on the punch; such as the pipe diameter of 8 mm below the general arbor press or pressurized equipment available.
