The elbow processing manufacturer tells you that the application and requirements of elbow processing are as follows:

(1) In practice, there are many different pipe bending processes for pipe bending processing.From this perspective, products can be divided into many different categories.In engineering, according to whether the elbow is heated, it can be divided into cold bending and hot bending.

(2) Depending on the number of bends of the elbow, it can be divided into cored elbows and centerless elbows with or without fillers.The stainless steel elbow is relatively thin, and the cold bending method is used in the bending process of stainless steel.

(3) Elbow products are inseparable from the use of stainless steel pipes in air conditioners, refrigerators, automobile oil circuits, heat exchangers, aerospace, etc.Elbow is one of the commonly used pipe fittings in pipeline installation projects.

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

(5) Each file on the pipe bender can set sixteen bending angles, and its memory can store sixteen sets of files.When used, it can be positioned according to its slow speed.The bending angle will not be disturbed, and the repeatability can reach ±0.1 degrees.

According to the elbow forming method, it can be divided into rolling bending, pressing bending, pushing bending and winding; according to whether a mold is used during bending, it can be divided into mold bending and non-mold bending; according to whether there is a mandrel during bending, it can be divided into core bending and coreless bending; according to whether it is heated during bending, it can be divided into cold bending and hot bending.In recent years, new bending technologies such as zero-radius bending, intermediate frequency induction bending, thermal stress bending and laser forming bending have emerged.

Rolling elbow is a method of bending a pipe with three rollers.Among them, roller 3 is the active wheel, and the other two are the driven wheels.The method and working principle of pipe bending are basically the same as that of sheet pipe bending, except that the rolls used for pipe bending have a working surface that conforms to the cross-section shape of the pipe billet.Only by changing the interval between the main roller and the slave roller can the bending of different radii of curvature be achieved.The tensile bending factory said that this method is particularly suitable for bending annular or spiral pipe fittings.However, rolling bending has certain requirements for the bending radius, and it is only applicable to thick-walled pipe fittings with a large radius of curvature, and it is powerless to bend with a small radius.

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