Processing technology of medium frequency elbow machine

Medium frequency elbow machine is an important pipe processing equipment, used to manufacture all kinds of bends and elbows. In the process of the intermediate frequency elbow machine, it is necessary to master a number of technologies, including material selection, mold design, processing technology, equipment debugging, etc. These aspects are explained in detail below, in order to better understand the processing technology of the intermediate frequency elbow machine.

First, material selection

In the manufacture of elbow, the choice of material is important. Usually, stainless steel, carbon steel, alloy steel and other materials can be selected, and the specific material selection should be considered according to the application and workpiece requirements. Common stainless steel 304, 316, 321, etc., carbon steel Q235, 20#, etc., alloy steel P5, P9, P11 and so on.

In the selection of materials need to pay attention to the following points:

1. The wall thickness and material of the elbow need to match the wall thickness and material of the pipeline to ensure that the processed elbow meets the requirements of strength and pressure resistance.

2. Material analysis and metallographic structure analysis are required after material selection in order to carry out accurate process parameter design.

3. The hardness and toughness of the material should be moderate, too hard will lead to damage, too soft is not easy to maintain the shape.

Second, mold design

The mold is a tool used to make elbows, and the design of the mold needs to be comprehensively considered according to the size, shape and material characteristics of the workpiece.

The main points of mold design are as follows:

1. The structural design of the mold should be reasonable, and the shape, wall thickness and curvature radius of the elbow need to be considered in the design of the mold.

2. The material of the mold should be matched with the processing material, with high hardness and toughness to ensure the processing quality.

3. The machining accuracy and surface quality of the mold should meet certain requirements to ensure that the surface of the machined elbow is smooth and the dimensional accuracy is high.

4, the mold in the process of processing need to consider a certain margin, in order to carry out subsequent correction and adjustment.

Third, processing technology

In the process of machining medium frequency elbow, it is necessary to master a certain processing technology, including the bending mode of elbow, the optimization of processing parameters, and post-processing.

The specific processing technology is as follows:

1. Bending method of elbow: Under normal circumstances, the outer diameter bending method is used to bend the pipe to the required Angle to form a bend. There is also an inner diameter bending method, which uses compression force to bend the elbow to the required Angle according to the required radius. Both methods need to be mastered according to the hardness and toughness of the material to avoid breakage.

2. Optimization of processing parameters: including processing speed, bending force, beating times, cooling methods, etc., need to be comprehensively considered according to different materials and elbow shapes to ensure processing quality.

3. Post-treatment: After the processing is completed, the elbow needs to be post-treated, mainly including surface cleaning, grinding, fever, etc., to improve the corrosion resistance and mechanical properties of the elbow.

Fourth, equipment debugging

The equipment debugging of medium frequency elbow machine is one of the important links of processing, which plays a vital role in the normal operation of equipment and the guarantee of processing quality. The operation required in equipment commissioning includes equipment installation, electrical equipment commissioning, pneumatic and hydraulic system commissioning, etc.

Equipment debugging should pay attention to the following points:

1. The installation of the device must meet the requirements to ensure the stability and stability of the device.

2. The commissioning of electrical equipment requires high voltage test, wiring debugging, etc., to ensure the normal operation of electrical equipment.

3. The debugging of pneumatic and hydraulic systems requires the adjustment of air pressure and oil pressure to make the system work normally.

The above is the introduction of intermediate frequency elbow machining technology, which involves many aspects such as material selection, mold design, processing technology and equipment debugging. In the processing process, it is necessary to carry out precise operation according to the nature of the material and the process requirements to ensure that the processed elbow size is accurate, the surface is smooth, and the mechanical properties are excellent.
