锻压法:用型锻机将管子端部或一部分予以冲伸,使外径减少,常用型锻机有旋转式、连杆式、滚轮式。
Forging method: The end or part of the pipe is stretched by a forging machine to reduce the outer diameter. The commonly used forging machines are rotary, connecting rod and roller.
冲压法:在冲床上用带锥度的芯子将管端扩到要求的尺寸和形状。
Stamping: The end of the pipe is extended to the required size and shape with a tapered core on the punch press.
滚轮法:在管内放置芯子,外周用滚轮推压,用于圆缘加工。
Roller method: Core is placed in the tube, and roller is used to push the edge.
滚轧法:一般不用芯轴,适合于厚壁管内侧圆缘。
Rolling method: generally no mandrel, suitable for thick-walled tube inside and outside the circular edge.
弯曲成形法:有三种方法较为常用,一种方法叫伸展法,另一种方法叫冲压法,第三种是大家较为熟悉的滚轮法,有3-4个辊,两个固定辊,一个调整辊,调整固定辊距,成品管件就是弯曲的。这种方法应用的较广,若生产螺旋管,曲率还可增大。
Bending forming method: There are three common methods, one is called stretching method, the other is stamping method, the third is the familiar rolling wheel method, there are 3-4 rollers, two fixed rollers, one adjusting roll, adjusting the fixed roll distance, the finished pipe is bent. This method is widely used. If spiral pipe is produced, the curvature can be increased.
鼓胀法:一种是在管内放置橡胶,上方用冲子压缩,使管子凸出成形;另一种方法是液压鼓胀成形,在管子中部充入液体,靠液体压力把管子鼓成所需要的形状,像我们常用的波纹管的生产大部分用的是这种方法。
Bulging method: one is to place rubber in the tube and compress it with a punch on the top to make the tube protrude; the other is to form the tube by hydraulic bulging, filling the liquid in the middle of the tube and bubbling the tube into the desired shape by the liquid pressure. This method is mostly used in our common bellows production.
