椭圆管加工常用方法1.锻压法:用型锻机将椭圆管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。2.冲压法:在冲床上用带锥度的芯子将椭圆管端扩到要求的尺寸和形状。3.滚轮法:在管内放置芯子,外周用滚轮推压,用于圆缘加工。4.滚轧法:一般不用芯轴,适合于厚壁管内侧圆缘。

Common methods of elliptical tube processing 1. Forging: Elliptical tube end or part is stretched by a forging machine to reduce the outer diameter. Common forging machines include rotary, connecting rod and roller type. 2. Stamping method: The elliptical tube end is expanded to the required size and shape with a tapered core on the punch press. 3. Roller method: the core is placed in the tube, and the outer part is pushed by the roller for the edge processing. 4. Rolling method: generally without mandrel, suitable for thick-walled tube inside and outside the circular edge. 5.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。6.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,液体压力把椭圆管鼓成所需要的形状,波纹椭圆管的生产大部分用的是这种方法。

5. Bending forming method: There are three commonly used methods, one is called stretching method, the other is stamping method, the third is roller method, there are 3-4 rollers, two fixed rollers, one adjusting roll, adjusting the fixed roll distance, the finished pipe is bent. 6. Bulging method: one is to place rubber in the tube and compress it with a punch on the top to make the tube bulge; the other is to fill the middle of the tube with liquid, and the liquid pressure makes the elliptical tube bulge into the desired shape. This method is mostly used in the production of corrugated elliptical tubes.
