Description

Bar processing rust removal device and rust removal method

Technical Field

The invention relates to a bar processing rust removal device and a rust removal method.

Background

The bar stock after mechanical processing is not processed efficiently because of the coating processing speed before the subsequent coating processing (usually, a production workshop is only provided with one coating process, and a plurality of processing machines are matched with the coating process). For this reason, stock backlogs of bar stock are created. During the stock overstock, the surface of the bar stock with part of the stock overstock time is rusted. In the plating process, rust removal of the surface is required. The existing processing mode adopts a large polishing machine, and the inner part of the polishing machine rotates, so that the surface of a bar can be damaged, and even the bar can be bent.

Therefore, the rod processing rust removal device and the rust removal method capable of achieving surface rust removal and polishing without rotation are designed.
