Common faults in copper pull-out mainly include the following:
? The welding is not strong ? :
The material of big drawn copper rod is soft, and it is easy to have the problem of unstable welding. This is usually caused by insufficient weld cleanliness,
welding current or time. In order to ensure welding strength, it is necessary to ensure that the weld is clean, and use sufficient current and welding time,
while avoiding overheating during the welding ?.
? stomata ? :
In the welding process, the formation of porosity is also a common problem. This may be due to reasons such as unclean welding materials, low welding
current or inappropriate electrodes. In order to solve this problem, it is necessary to ensure the cleanliness of the welding material, select the appropriate
electrode and current, and use argon as a protective gas during the welding process to prevent the generation of pores ?.
? disconnection ? :
Broken wire is another common fault in copper drawing process. It can be caused by a variety of factors, such as excessive oxygen content in the copper rod,
inclusions, poor wire drawing equipment (such as inappropriate eye mold entry Angle) and so on. These factors may cause the copper rod to be affected by
stress during the drawing process, resulting in distortion or small cracks, and finally breaking in the subsequent drawing process ?.
? uneven drawing ? :
Uneven drawing is also a common problem in the copper drawing process. This may be caused by die wear, uneven drawing speed or unstable drawing
temperature. The wear of the die will lead to the change of resistance during the drawing process, which will affect the uniformity of the drawing. The
instability of the drawing speed and temperature may cause uneven deformation of the copper rod during the drawing process ?.
? Equipment failure ? :
In addition to the above failures directly related to copper rods and materials, equipment failures are also problems that cannot be ignored in the copper
drawing process. For example, the motor does not work, the control system failure, etc., may cause the normal operation of the wire drawing machine to
be affected. For this kind of failure, it is necessary to carefully check the power line, motor status and electrical connection of the control system to ensure
the normal operation of the equipment ?.
In summary, the common faults in the copper drawing process include unstable welding, porosity, broken wire, uneven wire drawing and equipment failure.
In order to ensure the smooth progress of copper pulling and product quality, it is necessary to take corresponding preventive measures and coping strategies
for these failures.
