Why is the fiber laser cutting machine deformed during rolling and cutting?

by:Lxshow     2021-05-19

During the planning process of the fiber laser cutting machine, a detailed and rational selection was made for the relevant process parameters, tool styles, parameters, rolling temperature and smoothing conditions, and the actual selection of the fiber laser will be confirmed. The cutting machine process request can get ample contentment.

When the fiber laser cutting machine is rolling and cutting, following the rolling in of the wedge-shaped blade, the steel tube undergoes violent and complicated deformation under the use of radial pressure. This deformation, It is caused by the use of the blade edge and the use of both sides on the steel pipe. The cutting edge is used for steel pipes to produce deformations such as radial shrinkage, tangential expansion, and axial extension. The radial shrinkage includes the radial shrinkage of the copper pipe and the radial shrinkage of the material itself. The former refers to the reduction purpose caused by the movement of the material into the steel pipe, and the latter is the critical deformation of rolling and cutting. Only this steel pipe can be Plastic severance. After the knife edge rolls the workpiece, the one-sided material moves in the tangential direction, making the workpiece elliptical. The material at the lower part of the blade will also be deformed along the axial direction. At this time, tensile stress will be generated in the leather material, which will become the resistance of the deformation. The side of the blade is used for steel pipes to cause deformations such as radial contraction, tangential expansion, axial contraction and outer diameter expansion of the material. Here, the radial shrinkage and tangential expansion are similar to the deformation environment generated when the cutting edge is used. Axial contraction makes the lower part of the edge of the edge of the rhyme link leather produce a tensile force, and the expansion of the outer diameter means that the oblique surface is compressed. The material moves toward the outer diameter of the tube, so that the edge of the outer diameter of the workpiece is slightly raised and elliptical. All the above elliptical deformation caused by tangential enlargement and outer diameter enlargement. During the entire rolling and cutting process, it is found that the continuous overlap along the entire circumference will gradually weaken with the increase of the rolling depth, and even close to dissipate. The protruding shape caused by the expansion of the outer diameter will gradually flatten out under the application of roller rolling.

In the initial stage of rolling and cutting, the deformation is mainly caused by the use of the cutting edge of the blade. With the increase of the cutting depth, the use of both sides of the blade for deformation is increasing. Bigger. In the later stage of rolling and cutting, the continuous skin becomes thinner and thinner, so the resistance to radial shrinkage and deformation becomes smaller and smaller. At this time, the axial tensile stress generated by the axial shrinkage and deformation of the blade on both sides plays an important role. When the stress exceeds the tensile strength of the material, the steel pipe is cut.

Ten advantages of portable fiber laser cutting machine innovations

1. Greatly improve and weaken assembly safety and fire safety;

2. Closely open, both sides of the tube are flat after cutting, easy to follow the tail

3, high safety, no need to move the tube by hand during homework;

4 , It will not produce sparks and dust to the outside world when it is cut;

5, the efficiency is complete, it can cut all the established pipelines of the power system;

6. Short, fast, and save a lot of homework time;

7, provide portable homework facilities, you can plan and make decisions based on your homework (on-site);

8, cut All pipe materials such as steel, stainless steel, cast iron, copper, plastic, and multilayer pipes can be cut;

9. There is no detailed request for pipe diameter and homework channels;

10. Good quality and low price, high cost performance.

The safety application of fiber laser cutting machine is more important than all work

Living is the endless price of life. For the safety of life, please strictly obey the association Delineation.

Before applying the fiber laser cutting machine, it is necessary to ensure that the operators can safely operate the fiber laser cutting machine without causing work-related accidents. This is a hard work for the manufacturers, but also for me.

The safety application of fiber laser cutting machine must strictly obey the following points:

1. Wear one-sided protective equipment. What is required to be worn must be worn, and what cannot be worn must not be worn. For example, a female worker is required to wear a protective cap during the processing of a fiber laser cutting machine. If not, the hair will probably be twisted in. At the same time, it is requested not to wear gloves. If they are worn, the twisting of the fiber laser cutting machine may twist the gloves in, which will easily cause the hands to be twisted.

2. Before operating the fiber laser cutting machine, it is necessary to conduct a safety inspection of the fiber laser cutting machine equipment. Run it empty and confirm that it is normal before it can be put into operation.

3. During the operation of the fiber laser cutting machine, safety inspections must also be carried out according to regulations. Especially for fastened objects, check whether they are loose due to vibration, and re-fasten them in real time.

4. When the equipment belt is obstructed, it is absolutely impossible to combine applications to prevent chaos.

5. When the fiber laser cutting machine is running, it is strictly forbidden to adjust it by hand, and it is also not allowed to measure the parts by hand, or smooth, remove debris, etc. If necessary, immediately turn off the stopper.

6. The knives, fixtures and processed parts of the fiber laser cutting machine must be installed firmly and not loose.

7. The safe assembly of the machine must be used in accordance with the regulations, and it must not be removed or used.

8. When the fiber laser cutting machine is working, the operator shall not leave the working post, so as to prevent no one from taking punishment when there is doubt.

9. After the work is over, the switch should be closed, the tools and workpieces should be withdrawn from the working position, and the work field should be cleared, and the parts, fixtures, etc. should be placed neatly and cleaned Good fiber laser cutting machine equipment sanitation.

Guarding good talents is the real purpose of doing a good job.
