Abstract

The invention discloses a punching device for wooden-door stainless steel fittings. The punching device comprises a bench drill (1), wherein a clamping head (2) is fixed to a main shaft of the bench drill (1), a drill bit (3) is clamped on the clamping head (2), a cooling device (10) connected with the drill bit (3) is arranged below the clamping head (2), vertical convex ribs (4) are arranged onthe clamping face of the clamping head (2), and the clamped face of the drill bit (3) is provided with grooves (5) matched with the convex ribs (4); and the lower end of the drill bit (3) extends downwards to sequentially penetrates through a first through hole (102), a second through hole (108) and a third through hole (111), and the drill bit (3) is screwed through a screw (105) and then connected with a fixed plate (101). The punching device for the wooden-door stainless steel fittings has the advantages that the drill bit is not prone to be ablated and damaged, the stainless steel fittingscannot be smeared and scratched, and the punching efficiency is high.

Description

technical field [0001] The invention belongs to the field of punching equipment for wooden door hardware fittings, in particular to a punching device for wooden door stainless steel fittings. Background technique [0002] Workers generally use bench drills to drill holes on stainless steel fittings on wooden doors. However, due to the poor cutting performance of stainless steel, it is difficult to drill holes with bench drills. Grinding, causing the drill bit to be easily ablated and damaged. In order to avoid the ablation damage of the drill bit, workers can also use coolant or compressed air to cool the drill bit, but the coolant will adhere to the stainless steel fittings and dirty the stainless steel fittings; while the compressed air flow speed is fast, it will blow the chips to the surface of stainless steel fittings, thereby scratching the stainless steel fittings. In addition, due to the poor cutting performance of stainless steel, the drill bit receives a large re...
