Elbow machine, also known as pipe elbow forming machine, is a kind of equipment used for pipe bending and forming. It is widely used in petroleum, chemical, natural gas, water supply, heating and other fields of pipeline installation and maintenance. The following is a detailed introduction to the basic knowledge of the elbow machine.
First, the basic principle and structure of elbow machine
The basic principle of the elbow machine is to use the principle of mechanics to bend the material into the desired Angle and shape by applying external force to it. Elbow machine is mainly composed of fuselage, hydraulic system, control system and mold.
1. Fuselage: Fuselage is the main structure supporting the various components of the elbow machine, which is generally welded by steel plates. The stability and bearing capacity of the fuselage have an important impact on the working effect of the machine.
2. Hydraulic system: The hydraulic system is the power source of the elbow machine, which drives the hydraulic cylinder by generating pressure to complete the forming of the elbow. The hydraulic system is usually composed of oil tank, oil pump, hydraulic valve and hydraulic cylinder.
3. Control system: The control system is a elbow machine, which controls the forming process of the elbow by controlling the work of the hydraulic system. The control system usually consists of a control panel, electrical components and sensors.
4. Mold: Mold is a key part of the elbow machine, which determines the shape and size of the elbow. Molds are generally made of special materials with high hardness and have certain strength and wear resistance.
Second, the working principle and operation process of the elbow machine
The working principle of the elbow machine is to use the power provided by the hydraulic system to achieve bending of the elbow material by changing the position of the hydraulic cylinder. The operation process generally includes the following steps:
1. Preparation: First of all, place the elbow machine on a smooth ground, and connect the power supply and hydraulic tubing. Then, according to the required elbow size and Angle, select the appropriate mold, and install.
2. Adjust the mold: Adjust the position and Angle of the mold as needed, so that it is parallel and aligned with the workbench. After the adjustment, tighten the mold to ensure that it is stable.
3. Turn on the hydraulic system: turn on the power switch of the hydraulic system and start the oil pump to make the hydraulic system work. Then, adjust the hydraulic valve so that the piston of the hydraulic cylinder moves slowly.
4. Elbow forming: Place the pipe to be bent on the mold and clamp it with a clamp. Then, by operating the control system, the position of the hydraulic cylinder is adjusted so that it applies the appropriate force to bend the pipe into the desired Angle and shape.
5. Check and adjust: After the pipe is bent, take out the elbow for check. If the size and Angle of the elbow meet the requirements, continue the next process. If it does not meet the requirements, it is necessary to adjust the mold and operating parameters and re-bend.
Third, the advantages and applications of elbow machine
Elbow machine has the following advantages:
1. High efficiency: The elbow machine is hydraulically driven, with high work efficiency and production capacity. Compared with traditional manual bending, its working speed is faster and the forming quality is more stable.
2. Accuracy: The elbow machine accurately controls the position and strength of the hydraulic cylinder through the control system, which can achieve highly accurate bending and ensure the consistency of the size and Angle of the elbow.
3. Versatility: The elbow machine can be applied to pipe bending of different materials and specifications, and has strong adaptability. At the same time, it can also make a variety of elbow shapes, such as 90 degree elbow, 45 degree elbow and so on.
Elbow machine is widely used in petroleum, chemical, gas, water supply, heating and other fields of pipeline installation and maintenance. It can be used to manufacture various types of pipe elbows, such as elbows, elbows, tees, four-way pipes, etc. At the same time, it can also be applied to the production of pipe fittings, pipe connections and other processes.
To sum up, the elbow machine is a kind of equipment for pipe bending and forming, and its basic principle is to use the power provided by the hydraulic system to achieve bending of the elbow material by changing the position of the hydraulic cylinder. It has the advantages of high efficiency, accuracy and versatility, and is widely used in pipeline installation and maintenance in various industries.
