When using honing tubes, attention should be paid to:
When the honing tube is dented, the life of key components will be affected, and most cylinder components will also affect the normal use of the entire system. What is the reason for the indentation. There are several possibilities:.
1. During the cold drawing process, the diameter of the Steel Pipe is reduced too much, or the steel pipe hammer head transitions too quickly.
2. The thickness of the pipe wall is uneven and the local thickness is too thin.
3. The honing equipment is too old and cannot meet the processing requirements of the pipeline.
When the honing tube is dented, the life of key components will be affected, and most cylinder components will also affect the normal operation of the entire system. The reasons for the concave fold are as follows:.
1. During the cold drawing process, the diameter of the steel pipe is too large and the hammer head of the steel pipe transitions too quickly.
2. The thickness of the pipe wall is uneven and the local thickness is too thin.
3. The honing equipment is too old and cannot meet the processing requirements of the pipeline.
In view of the concave bending problem of the honing tube, a specific processing method was proposed based on the need to reasonably distribute the shrinkage of the honing tube during the cold drawing process. Eliminate defects in hammer heads and pipes and replace traditional honing equipment. After all these improvements, similar flaws should also be improved.
Honed tubes do not have the following advantages:
1. Improve processing efficiency: the processing speed is nearly twenty times that of honing.
2. Improve surface hardness: surface hardness is increased by more than 50%.
3. Processing accuracy: The processing accuracy can reach IT level 8, and the surface roughness can reach Ra 0.05 -0.4μm.
4. Working environment: low noise, no pollution, saving labor costs5. Reasonable processing procedures: After other processes (such as oil drilling, welding, thread processing, etc.) are completed, scraping and rolling can be used as the last process. The processing principle of pipe rolling: It is a kind of calendering finishing. It uses the cold plastic properties of metal at normal temperature and uses rolling tools to exert a certain pressure on the surface of the workpiece to cause the metal on the metal surface to flow plastically and fill the original material. Some grooves reduce the surface roughness of the workpiece. No matter how the rolled pipe is processed, tiny protrusions and uneven marks will appear on the surface of the part.
