Information

Elbow is a complete set of bending die for bending, no matter what kind of machine equipment, most of them are used for oil, gas, infusion, etc., which plays an important role in aircraft and its engine. In such an important use, how much do we know about the processing method of elbow? The following Guanghe valve editor will tell you about the five methods commonly used in elbow processing.

1、 Stamping method: on a punch press, the end of the tube is expanded to the required size and shape with a tapered core.

2、 Bending forming method: there are three commonly used methods, one method is called stretching method, the other method is called stamping method, and the third method is roller method, which has 3-4 rollers, two fixed rollers, one adjustment roll, and adjusts the fixed roll distance. The finished pipe fittings are bent.

3、 Bulging method: one is to place rubber in the pipe, and the upper part is compressed with a punch to make the pipe protrude into shape; the other method is hydraulic bulge forming, in which liquid is filled into the middle of the pipe, and the liquid pressure bulges the elbow into the required shape. This method is used in most of the production of bellows

4、 Forging method: the end or part of the pipe is punched and stretched with a die forging machine to reduce the outer diameter of the pipe. The commonly used forging machines are rotary type, connecting rod type and rolling wheel type. 3. Roller method: the core is placed in the pipe, and the outer circumference is pushed by the roller, which is used for the processing of circular edge.

5、 Rolling method: generally without mandrel, it is suitable for the inner edge of thick wall pipe.
