Problems solved by technology

[0004] However, it is not enough to absorb the heat generated during the friction process of the drill bit only through the heat-absorbing medium set inside, and this cooling method can only cool a little heat of the drill bit, and has no cooling effect on the workpiece rubbed against it, so the overall poor cooling

Abstract

The invention discloses a self-cooling type drill bit. A cavity is formed in the drill bit. The drill bit comprises a drill bit body at the top, a drill rod in the middle and a connecting portion with the tail pivoted to a drill bit seat. The drill bit body is in an inverted conical shape. The drill rod is in the shape formed by connecting at least two inverted circular truncated cones. The drill bit body and the drill rod are provided with multiple holes communicating with the cavity in the drill bit. A pivot joint segment body is connected with two pipes extending outwards, namely the grinding aid liquid pipe and the cooling gas pipe. The outer portion of the cooling gas pipe is connected with an air compressor. The outer portion of the grinding aid liquid pipe is connected with grinding aid equipment. The drill bit integrates drilling, lubricating and cooling, lubricating can be conducted while drilling, and no extra cooling and lubricating device needs to be designed for drilling equipment, so that the drill bit equipment is simplified. When the drill bit works, drilling and grinding efficiency can be improved through grinding aid, and the edges of drilled holes are smooth and not sharp and coarse.

Description

technical field [0001] The invention relates to a drill bit, in particular to a self-cooling drill bit, which belongs to the technical field of machining. Background technique [0002] Traditional drills are all solid drills. For example, the application number is 201520621081.7, and the name of the invention is a three-edged drill. When used with a drilling machine or a machine tool, it is necessary to add additional coolant and a cooling mechanism to the drilling machine or machine tool, which increases the capacity of the machine tool. Occupying an area, and placing cooling liquid tanks and liquid pipes outside the machine tool increases the burden on operators. [0003] For another example, the application number is 201420811478.8, and the title of the invention is a cemented carbide internal cooling drill. Cooling pipes are arranged inside the drill bit and the drill shank; the hollow cavity of the cooling pipe is filled with an absorption heat transfer medium; Both en...
