ElbowThe processing factory tells you the application and requirements of bending pipe processing are as follows:

(1) In practice, there are many different bending processes for bending pipe processing. From this point of view, products can be divided into many different categories. In engineering, according to whether the elbow is heated or not, it can be divided into cold bending and hot bending.

(2) According to the different bending times of the elbow, whether there is filler or not can be divided into cored elbow and centreless elbow. Stainless steel pipe bending is relatively thin, stainless steel pipe bending process using cold bending method.

(3) elbow products are inseparable from the use of stainless steel pipes in air conditioners, refrigerators, automobile oil circuits, heat exchangers, aerospace and other aspects.ElbowIt is one of the pipe fittings commonly used in pipeline installation engineering.

(4) The elbow mainly uses its touch screen and CNC module to play and shut down, and adopts its dialogue mode. The product adopts the program setting, the use process is simple and easy. The bed structure of the whole equipment is stable and not easy to deform.

(5)ElbowEach file on the machine can set sixteen bending angles, and its memory can store sixteen groups of files. When in use, it can be positioned according to its slow speed. The bending angle will not be disordered, and the repetition accuracy can reach ± 0.1 degrees.

According to the bending forming method, it can be divided into roll bending, press bending, push bending and winding bending. According to whether the mold is used during bending, it is divided into mold bending and non-mold bending. According to whether there is a mandrel during bending, it can be divided into cored bending and coreless bending. According to whether heating is used during bending, it can be divided into cold bending and hot bending. In recent years, new bending technologies such as zero radius bending, medium frequency induced bending, thermal stress bending and laser forming bending have emerged.

Roll bending is a method of bending a pipe with three rollers. The roller 3 is a driving wheel, and the other two are driven wheels.ElbowThe method and working principle are basically the same as the sheet bending, except that the roll used for pipe bending has a working surface that conforms to the cross-sectional shape of the tube blank. Only by varying the spacing between the master and slave rollers can bends of different radii of curvature be achieved. The stretch bending plant shows that this method is particularly suitable for bending circular or spiral pipes. However, rolling bending has certain requirements for bending radius, which is only applicable to thick-walled pipe fittings with large radius of curvature, and is powerless for small radius bending.

ElbowThe bending process method. It uses a mold to bend the tube blank on a hydraulic press. The elbow has the advantages of simple mold adjustment and high production efficiency, so it has been widely used in production, generally used for elbow or straight elbow.
