Description

Technical Field

[0001] The utility model belongs to the technical field of fine steel material preparation, in particular to a novel grinding device for copper rod production. Background Art

[0002] Copper rods are raw materials for the production of wires and cables. After the oxygen-free copper rods are forged, many burrs will be generated on their surfaces. The burrs and uneven places on their surfaces need to be polished smooth to facilitate subsequent water washing, pickling, polishing, drying and painting. In the copper rod polishing process, manual polishing and mechanical polishing are generally used. Manual polishing has low work efficiency and is not applicable to the existing copper rod production process. Mechanical polishing, as the current mainstream polishing method, also has the following defects. First, the copper rod introduction of the existing polishing equipment requires manual auxiliary feeding. The copper rod must be fixed on the turntable fixture before the polishing equipment can be started to polish the surface of the copper rod. After the work is completed, it needs to be manually disassembled from the turntable fixture, which is cumbersome. Second, during the polishing process, the polished copper wire falls directly on the bottom surface and cannot be collected uniformly. Two to three shutdowns are required for cleaning every day, which affects work efficiency. Therefore, a device that can automatically feed, reciprocately polish the copper rod, and collect the polished copper wire is designed. Utility Model Content

The grinding mechanism is an important component for copper rod grinding. In order to realize reciprocating grinding of the internal copper rod, the entire grinding structure is arranged on the movable bracket 5, wherein the movable bracket 5 can be moved under the rotation of the screw 6, and the screw 6 here can be replaced with a reciprocating screw as needed, and driven by the drive box; and the roller 28 is arranged on the upper part of the movable bracket 5, and can rotate the entire roller 28 under the drive of the first drive group.
