The engine also occupies a very important position

When the pipe is bent, the stamping method is used: on the punching machine, a tapered core is used to expand the pipe end to the required size and shape; afterwards, the bending forming method is also used. There are three methods that are commonly used. One method is called stretching. The method, the other method is called the stamping method, the third roller method, there are 3-4 rollers, two fixed rollers, an adjusting roller, adjusting the fixed roller distance, the finished pipe is curved.

    The bulging method is also used in the bending process: one type of rubber is placed in the tube, and the upper part is compressed with a punch so that the tube is convexly formed; the other method is hydraulic bulging forming. The middle part of the tube is filled with liquid and the liquid pressure bends. The shape of the tube drum is required for most of the production of the bellows.

    Finally, we must also pay attention to daily life and work. Inevitably you will encounter straight tubes that are bent into various shapes for use. The bent pipe is bent using a complete set of bending dies. No matter which type of machine or equipment is used, most of them are used for bent pipes. They are mainly used for oil transportation, gas transmission, infusion, and so on. They also play an important role in aircraft and its engines. status.
