How to choose pipe bending machine

Tube bending machine processing technology can be divided into many types, mainly including stretch bending, winding bending, push bending and other methods. These methods can be divided into two bending states: cold bending and hot bending. The processing technology applied to different elbows is different, and the characteristics of different elbows are also different.

Different types of roller bending machine

The intermediate frequency roller bending machine is used to connect two pipes with the same nominal diameter to make the pipeline make a 90-degree turn.

In addition to carbon, intermediate frequency roller bending machine generally contain a small amount of silicon, manganese, sulfur, and phosphorus. Carbon steel can be divided into three types: carbon structural steel, carbon tool steel and free-cutting structural steel according to its purpose. Carbon structural steel It is divided into two types: building structural steel and machine-made structural steel;

The crafting process of bending pipe

The forming process of the intermediate frequency elbow is complicated. It needs to be welded according to different materials and purposes, and gradually formed under a certain pressure. The forming of the intermediate frequency elbow needs to be carried out in accordance with a certain process and strictly abide by the corresponding process, otherwise the produced intermediate frequency pipe bending machine will have quality problems.

The material of intermediate frequency elbow has high viscosity and poor chip breaking performance. Therefore, in the process of tapping for stainless steel intermediate frequency tube bender, it is easy to cause the phenomenon of chip scratches on the workpiece thread or tap chipping, which affects the processing efficiency and thread quality. According to the material, the intermediate frequency elbow can be divided into: carbon steel intermediate frequency pipe bender, stainless steel intermediate frequency elbow, alloy steel intermediate frequency pipe bender; according to the standard can be divided into: national standard intermediate frequency tube bender, non-standard intermediate frequency elbow, international standard: German standard, Japanese standard, American standard, British standard intermediate frequency tube bender.

Features of different types of roller bending machine

Features of IF  pipe bending machine:

1. Use a power supply with vertical external characteristics, and use positive polarity when direct current (welding wire connects to negative pole)

2. Generally suitable for the welding of thin plates below 6mm, with the characteristics of beautiful weld shape and small welding deformation

3. The protective gas is argon with a purity of 99.99%. When the welding current is 50~50A, the argon flow rate is 8~0L/min, when the current is 50~250A, the argon flow rate is 2~5L/min.

4. The protruding length of the tungsten electrode from the gas nozzle is preferably 4~5mm, 2~3mm for fillet welding and other places with poor shielding, 5~6mm for deep grooves, and the distance from the nozzle to the working distance is general. No more than 5mm.

5. In order to prevent the appearance of welding pores, if there is rust and oil stains on the welding part, it must be cleaned up.

6. For welding arc length, 2~4mm is better when welding ordinary steel, and ~3mm is better when welding stainless steel. If it is too long, the protection effect will not be good.

7. In order to prevent the back surface of the bottom layer welding bead from being oxidized, the back surface also needs to be protected by gas.

8. In order to make the argon gas well protect the welding pool and facilitate the welding operation, the center line of the tungsten electrode and the welding workpiece should generally maintain an angle of 80~85*, and the angle between the filler wire and the surface of the workpiece should be as small as possible. -Generally around 0.

At present, petrochemical pipelines, electric power and other industries need a large number of pipe bending machine products,,also provide Saw Blade Sharpener, Chamfering Machine and the bending pipe market has a bright future. Pipeline storage and transportation company Petroleum Machinery Maple Plant has developed a large-caliber intermediate-frequency heating hydraulic propulsion pipe bender. Its successful development has filled the blank of this domestic project and has far-reaching significance. So choosing a good pipe bender is very important. Zhangjiagang King-Macc Machinery Manufacturing Company can provide you with the best products.
