ntroducing the processing method of Concrete Pump Pipe

There are many kinds of processing methods for Concrete Pump Pipe, many of which are also in the category of machining. The most used are stamping, forging, roller processing, rolling, bulging, stretching, bending, and combination. Processing method.
Concrete Pump Pipe processing is an organic combination of machining and metal pressure processing.
Concrete Pump Pipe is illustrated as follows:
Forging method: The end or part of the pipe is punched out by a swaging machine to reduce the outer diameter. The common forging machine has a rotary type, a link type and a roller type. Stamping: The tube ends are expanded to the required size and shape with a tapered core on the press.

Roller method: The core is placed in the tube, and the outer circumference is pressed by a roller for round edge processing.
Rolling method: Generally, the mandrel is not used, and it is suitable for the inner edge of the thick-walled pipe.
Bending forming method:
There are three methods that are more common.
One method is called stretching method, the other method is called stamping method, and the third method is the roller method which everyone is familiar with. There are 3-4 rollers, two fixed rollers, one adjusting roller, and the fixed roller distance is adjusted. The finished pipe fitting is Bent.
This method is widely used, and if the spiral tube is produced, the curvature can be increased.
Inflating method: one is to place rubber in the tube, and the upper part is compressed by a punch to make the tube convex and convex; the other method is to form a hydraulic bulge, fill the middle of the tube with liquid, and the liquid pressure drums the tube into a desired shape. Most of the production of bellows like ours is used in this way.
