Elbow machine is a kind of mechanical equipment commonly used in pipeline processing, which is used for bending, bending and forming elbows of metal pipes. The basic process includes pipe preparation, bending operations and finished product handling. The basic process of the elbow is described in detail below.
First, pipeline preparation
Pipe preparation is a step in elbow machining, which mainly includes pipe selection, cutting and cleaning.
1. Pipeline selection
Choosing the right pipe material is an important factor to ensure the quality of the finished product. According to the actual needs to choose the appropriate material, common carbon steel, stainless steel, copper, aluminum and so on. According to pipe diameter and wall thickness and other parameters, determine the appropriate elbow model number and process parameters.
2. Pipe cutting
Depending on the desired bend shape and length, use a pipe cutter or hand cutting tool to cut the pipe. Ensure that the incision is smooth and free of burrs for subsequent operations.
3. Pipe cleaning
After cutting, use a metal brush or other cleaning tools to clean the surface of the pipe to remove impurities such as dust, oil, and oxides generated during cutting to ensure that the surface of the pipe is smooth and clean for subsequent operations
Bending operation is the core of elbow machining, which mainly includes the steps of bending pipe clamping, elbow setting, bending and elbow measurement.
1. Clamp the bent pipe
Put the cut and clean pipe into the clamp of the elbow machine and clamp the pipe to ensure that it is fixed. Clamps are usually hydraulically or mechanically clamped to ensure that the pipe does not slip or deform during bending.
2. Elbow setting
Adjust the setting parameters of the elbow machine according to the required elbow Angle and radius. By controlling the hydraulic system or electronic control system of the elbow machine, the bending Angle, radius and speed are set to ensure the precision and smoothness of the bending.
Step 3 Bend
Start the elbow machine to bend the pipe in the clamp by hydraulic or mechanical force. During the bending process, maintain appropriate speed and pressure to avoid pipe or rupture. Depending on the type and control of the bending machine, the bending process can be automated or manual.
4. Bend measurement
According to the bent pipe, the Angle and radius of the bend are measured by measuring instruments such as Angle meter and radius gauge. Through the measurement results, the parameters of the bending machine are adjusted to make the bending meet the expected requirements.
Third, finished product processing
Finished product treatment refers to the painting, rust removal and packaging of pipes that have been bent to protect the pipes and improve the quality of the product.
Step 1 Paint
Solid elbows are painted to prevent oxidation, corrosion and wear of pipes. Select the appropriate coating and coating process, coating the coating evenly on the surface of the pipeline to form a protective film.
2. Remove rust
For the pipes that need to be removed, rust remover or mechanical tools are used to remove rust on the surface of the pipes to remove the rust and oxides on the surface to ensure the surface finish and quality of the pipes.
Step 3: Packaging
The finished elbow is packaged to prevent damage and contamination during transportation. Common packaging methods include cartons, wooden cases, woven bags, etc., to ensure the integrity of the finished product and the quality of the product.
The above is the basic process of the elbow machine, which includes three main links: pipeline preparation, bending operation and finished product treatment. The quality and accuracy of the finished product of elbow machining can be guaranteed by strictly controlling the quality and operation specifications of each link. It should be noted that there may be some subtle differences between different types of elbow machines, and the specific operation and parameter Settings should be carried out according to the instruction manual and actual operating experience of the equipment.
