Metal surface treatment process

Abstract

The invention discloses a metal surface treatment process which comprises a bottom board. A column is fixedly arranged on the top end face of the bottom board. An installation seat is fixedly arrangedon the top end face of the column. A working frame is arranged at the left side end of the installation seat. First penetrating holes are bilaterally symmetrically formed in the bottom end face of the working frame. Adjustment cavities extending up and down are formed in the inner top walls of the first penetrating holes. Conic tooth frames are installed on the bottom walls of the adjustment cavities in a running fit mode. Outer gear rings are fixedly arranged on the peripheries of the conic tooth frames. Second penetrating holes opposite to the first penetrating holes are formed in the conictooth frames in an up-down run-through mode. Adjustment frames are installed in the adjustment cavities in a sliding fit mode. Bevel gears used for being engaged with the conic tooth frames are installed at the bottom ends of the adjustment frames in a running fit mode. Drill bits are fixedly installed on the bottom end faces of the bevel gears and extend into the second penetrating holes and thefirst penetrating holes. A through cavity is formed between the bottom ends of the adjustment cavities in the left side and the right side in a communicating mode.

Description

technical field [0001] The invention relates to the technical field of sheet metal processing, in particular to a metal surface treatment process. Background technique [0002] During the production and processing of sheet metal, the drilling of traditional sheet metal mainly relies on manual adjustment and replacement of the drill bit, which is less efficient. When the drill bit needs to be replaced repeatedly, it needs to be disassembled repeatedly, which greatly affects the quality and speed of the sheet metal preparation, and the traditional The punching equipment is inconvenient to adjust the rotation direction of the drill bit. Therefore, the punching has strong limitations and is inconvenient to use, which affects the production and processing efficiency of the metal sheet and needs to be improved. Contents of the invention [0003] The object of the present invention is to provide a metal surface treatment process for overcoming the above-mentioned defects in the p...
