厂家解读弯管加工的常用五种方法介绍

发布时间:2019-05-17人气:93

专家解读弯管加工的常用五种方法介绍
一.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。 
二.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。 
三.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,液体压力把弯管鼓成所需要的形状,波纹管的生产大部分用的是这种方法
四.锻压法:用型锻机将管子端部或一部分予以冲伸,使管件外径减少,常用型锻机有旋转式、连杆式、滚轮式。 3.滚轮法:在管内放置芯子,外周用滚轮推压,用于圆缘加工。 
五.滚轧法:一般不用芯轴,适合于厚壁管内侧圆缘。

Experts interpret five commonly used methods of elbow machining:
Stamping method: expanding the pipe ends to the required size and shape with a taper core on the punch press.
Two. Bending forming: there are three methods more commonly used. One is called extension method. The other is called stamping and third roller methods. There are 3-4 rolls, two fixed rollers, one adjusting roller, fixed roll distance, and the finished pipe fittings bend.
Three. Bulging: one is to place rubber in the tube, and the top is compressed by a punch to make the tube bulge; the other is hydraulic bulging, filled with liquid in the middle of the tube, and the pressure of the liquid is drums into the desired shape. The production of the bellows is mostly used in this method.
Four. Forging and pressing method: forging the end or part of the pipe to be used to extend the outer diameter of the pipe. The common forging machine has revolving, connecting rod type and roller type. 3. roller method: put the core in the tube, push the roller around the periphery for the round edge processing.
Five. Rolling method: generally do not use mandrel, suitable for thick walled tube inner rim
