Detail

In the production process of making steel pipes on the high frequency welded pipe machine production line, three links of raw materials, welding technology and roll adjustment should be focused on control.

 

High frequency welded pipe machine

 

The high frequency welded pipe machine must control the roll adjustment at last

It can be seen from the causal analysis diagram of steel pipe waste produced during the production of the high frequency welded pipe machine that roll adjustment is a steel pipe operation process. In the production process, when the rolls are damaged or worn severely, some rolls need to be replaced on the unit, or a certain variety has been continuously produced in sufficient quantities, and the entire set of rolls needs to be replaced. At this time, the rolls should be adjusted to obtain good steel pipe quality. If the rolls are not adjusted properly, it is easy to cause the torsion, lap welding, edge waves, bulging and indentation or scratches on the surface of the pipe body, and large ovality of the steel pipe. Therefore, the roll adjustment should be mastered when changing the rolls. Skill.

 

(1) To change the steel pipe specifications, the complete set of rolls is generally replaced. The method of roll adjustment is: use a steel wire to pull a center line from the unit entrance to the exit, and adjust so that the hole pattern of each frame is on a center line and the bottom line of the forming meets the technical requirements. After changing the roll specifications, first make a comprehensive adjustment of the forming roll, guide roll, squeeze roll, and sizing roll, and then focus on the closed pass, guide roll, and squeeze roll adjustment of the forming roll.

 

(2) The role of the guide roller is to control the direction of the pipe seam of the steel pipe and the height of the bottom line of the pipe blank, ease edge extension, control the rebound of the pipe blank edge, and ensure that the pipe seam is straight and does not twist into the squeeze roller. If the guide roller is not well adjusted, it is easy to cause welding defects such as torsion, lap welding, and edge waves during the welding of the steel pipe.

 

High frequency welded pipe machine

 

(3) The squeeze roller is the key equipment of the pipe welding unit, and its function is to complete the pressure welding of the pipe body with the edge heated to the welding temperature under the squeeze force of the squeeze roller. In the production process, it is necessary to control the size of the opening angle of the squeeze roller. If the squeezing force is too small, the strength of the weld metal will decrease and cracks will occur after the force is applied; if the squeezing force is too large, the welding strength will be reduced, and the amount of external burrs will increase, which is likely to cause welding defects such as lap welding.

 

(4) During the slow start process of the high frequency welded pipe machine, pay close attention to the rotation of the rollers at all parts, and adjust the rollers at any time to ensure that the welding quality and process dimensions of the welded pipe meet the specified requirements.

 

High frequency welded pipe machine

 

The three important links of raw material, welding and roll adjustment in the production process of welded steel pipes are carried out on the high frequency welded pipe machine. If strict control is implemented, the quality of welded pipes will be effectively improved.

Apply of Bedroom screw looping
Apply of Bedroom screw looping
Time of issue : 2024-12-03
Bedroom screw looping (generally used in the field of metal working, such as steel rolling) is a device used for specific processing operations. Used roller bedroom spiral looper can still work effectively after proper maintenance and debugging. Its operation mainly includes the following aspects:

1.Basic construction: A typical roller type bedroom spiral hoop usually consists of two sets of rollers that form a spiral shaped channel for guiding and supporting the metal strip.

2.Operation principle: When the metal strip passes through the looper, the strip is guided and supported in the spiral path. Due to the spiral structure of the looper, the strip can be smoothly transmitted under the condition of uneven strip speed to ensure the normal progress of the subsequent process.

3.Commissioning and maintenance: Used equipment needs to be inspected and maintained in detail before use. Includes:
Cleaning: Remove oil, dust and so on from the surface.
Lubrication: Check and add lubricating oil to ensure the normal operation of each transmission component.
Calibration: Ensure that the neutralization pressure of the roller is set correctly.
Replacement parts: Check for wear and replace necessary parts.

4.Application process: In the process of use, it is necessary to pay attention to the operation specifications, monitor the operating status of the equipment, and adjust the equipment parameters in time to meet the strip specifications and process requirements. In addition, it is also necessary to pay attention to safe operation to prevent accidents.

Through the above methods, the used roller bedroom spiral looper can continue to play its function and provide support for metal processing production.
