Description

Technical Field

[0001] The utility model relates to the technical field of production and processing of oxygen-free copper rods, in particular to a grinding device for production of oxygen-free copper rods using an upward drawing method. Background Art

[0002] At present, oxygen-free copper rods are mainly produced by the upward continuous casting method. Due to the characteristics of the upward continuous casting method, the oxygen-free copper rods produced will have obvious indentations after passing through the traction wheel, resulting in defects such as pores and indentations on the surface of the oxygen-free copper rods. Therefore, the surface of the copper rods needs to be polished during the subsequent processing.

[0003] However, since the oxygen-free copper rod is produced using the upward-pulling method, it cannot rotate like other objects during grinding, resulting in poor compatibility between the existing grinding device and the oxygen-free copper rod. In addition, the waste chips generated during grinding will adhere to the copper rod, making it inconvenient to clean.

[0004] Therefore, we propose a grinding device for oxygen-free copper rod up-drawing production to solve the above problems. Utility Model Content
