Detail
The used high-frequency tube mills is the core equipment of the entire HFW production line, and it is also the equipment with the highest technical requirements. If it is adjusted improperly, it will directly affect the quality of the welded pipe. This article takes five-roll extrusion welding as an example to introduce the used high frequency tube mills in detail. Common problems of high-frequency welding of machines (3)——According to the shape reason and adjustment method of the wrong edge.
The shape and adjustment of the wrong side
When the used high-frequency tube mills runs high-frequency welding, the wrong edge of the plate edge (also called lap welding) often occurs. In addition, the wrong edge of the plate edge is an important reason that affects the welding quality. If the adjustment is improper, the wrong edge will appear, which reduces the effective wall thickness of the welding seam, and it is easy to cause stress concentration here.
Fig. 9 shows the shape of normal docking.
Figure 10 shows the wrong edge caused by the different height of the board edge, which is a common welding wrong edge.
The reasons for the wrong edge in Figure 10 are:
(1) In most cases, the height of the two upper squeezing rollers is different. Therefore, it can be corrected by adjusting the height of one of the upper squeezing rollers.
(2) Sometimes it is caused by the different heights of the welding squeeze side rollers, which can be corrected by adding or subtracting metal gaskets at the bottom or side of the squeezing side roller frame.
Figure 11 shows the edge misalignment caused by the different angles of the welded plates. Such misalignment can easily cause the welding burrs to fall to one side. The metallographic test of high-frequency welding shows the bending of the fusion line or the asymmetrical angle of the left and right streamlines of the fusion line.
Reasons for such wrong edges:
(1) The roller position of the upper welding roller is asymmetrical along the rolling center of the welded pipe, which causes the two upper rollers to exert unequal force on the two plate edges. The upper roller frame can be adjusted horizontally to make the entire upper roller simultaneously Move to the left or right, and finally reach the center of the upper squeeze roller (Figure 12).
(2) The height of the two squeezing side rollers is different or the squeezing roller frame is inclined.
(3) Reasons for edge quality. The strip steel has defects such as sickle bends, wavy bends, etc., or the single side plate edge of the strip steel is worn out.
The above problems are the reasons for the shape and adjustment methods of the wrong side of the used high-frequency tube mills during high-frequency welding. I hope to give you effective help.

The Role of Roller Conveyor Motors in Used Pipe Welding Machines
Time of issue : 2025-03-05
Used pipe welding machines refer to welding equipment that has been previously used and is resold, typically for producing welded steel pipes. In used pipe welding machines, the roller conveyor motor is a critical component whose role runs through the entire production process, directly affecting the equipment's operational efficiency, processing accuracy, and product quality. Below is an analysis of the main functions and importance of roller conveyor motors in used pipe welding machines.
1. Transporting Pipe Materials
The primary function of the roller conveyor motor is to drive the rollers, transporting pipe materials from one process to the next. During pipe welding production, the pipe material needs to go through multiple stages, including uncoiling, forming, welding, cooling, sizing, and cutting. The roller conveyor motor ensures smooth and continuous movement of the pipe material by controlling the rotation of the rollers, preventing jams or deviations.
2. Ensuring Production Continuity
In used pipe welding machines, the stable operation of the roller conveyor motor is key to ensuring production continuity. If the motor fails, it may cause interruptions in material transportation, affecting the efficiency of the entire production line. Therefore, the reliability and durability of the roller conveyor motor are particularly important, especially in used equipment, where regular maintenance and care are essential.
3. Controlling Pipe Material Speed
The roller conveyor motor controls the speed of the rollers through a speed regulation device, thereby adjusting the transportation speed of the pipe material. During the welding process, the transportation speed of the pipe material must match the welding speed to ensure weld quality. The precise control capability of the roller conveyor motor directly affects welding results and production efficiency.
4. Improving Processing Accuracy
The smooth operation of the roller conveyor motor helps reduce vibrations and deviations during material transportation, thereby improving processing accuracy. In used pipe welding machines, the performance of the roller conveyor motor may decline due to equipment aging, so regular inspection and maintenance are necessary to ensure its operational precision.
5. Adapting to Multiple Specifications
Roller conveyor motors are typically equipped with speed regulation functions, allowing them to adapt to the production of pipes with different specifications. For example, when producing thin-walled and thick-walled pipes, the motor needs to adjust its speed to meet different processing requirements. This flexibility enables used pipe welding machines to fulfill diverse production needs.
6. Energy Saving and Efficiency
Modern roller conveyor motors are often designed for high efficiency and energy savings, reducing energy consumption and improving production efficiency. In used pipe welding machines, if the motor is aging or its performance declines, energy consumption may increase. Therefore, it is recommended to upgrade or replace the motor to enhance the overall energy efficiency of the equipment.
7. Reducing Equipment Wear
The smooth operation of the roller conveyor motor can reduce wear on other components of the equipment. For instance, if the motor operates unstably, it may cause premature wear on rollers, bearings, and other parts, increasing maintenance costs. Thus, in used pipe welding machines, the condition of the roller conveyor motor directly impacts the equipment's service life.
8. Automation Control
In modern pipe welding production lines, roller conveyor motors are often integrated with PLCs (Programmable Logic Controllers) and sensors to achieve automated control. In used pipe welding machines, if the roller conveyor motor supports automation functions, it can significantly improve production efficiency and product quality.
9. Safety
The stable operation of the roller conveyor motor is also closely related to production safety. If the motor fails, it may lead to material pile-ups, equipment jams, or even injuries. Therefore, in used pipe welding machines, the safety of the roller conveyor motor cannot be overlooked.
10. Maintenance and Care
In used pipe welding machines, the maintenance of the roller conveyor motor is particularly important. Since the equipment has been used for a certain period, the motor's performance may have declined. Regularly checking the motor's insulation, lubrication, and operating temperature can extend its service life and ensure stable equipment operation.
Conclusion
The roller conveyor motor plays a vital role in used pipe welding machines, with its functions covering material transportation, speed control, processing accuracy, energy efficiency, and more. For used equipment, the condition of the roller conveyor motor directly affects the overall performance and production efficiency of the equipment. Therefore,
