Description
Technical Field
The utility model relates to a drill bit field, more specifically say, relate to a novel but coping alloy drill bit.
Background
In the machining process, a drill bit is inevitably used for punching, and the drill bit generally comprises a connecting rod, a cutter head and a clamping head.
But the during operation drill bit of current drill bit structure mainly leans on percussion pressure, makes medium crushing speed slow, and the tool bit bursts apart easily moreover, unable coping, sets up single spiral blown down tank moreover, and discharging efficiency is lower, leads to the fact the interference to the tool bit easily to dress chuck is unfavorable for the location installation, and the result of use is unsatisfactory.
SUMMERY OF THE UTILITY MODEL
To the problem that exists among the prior art, the utility model aims to provide a novel but coping alloy drill bit sets up four cutting blades of pentagon structure on the tool bit surface, two plane cutting edges, makes things convenient for the coping to do benefit to the operation of punching, set up interval distribution's plane and arc surface on dress chuck surface moreover, do benefit to the location installation, can improve convenience and the stability of use like this greatly, guarantee the high security of punching.
In order to solve the above problems, the utility model adopts the following technical proposal.
The utility model provides a novel but coping alloy drill bit, includes the connecting rod, the surface of connecting rod is equipped with the blown down tank, the fixed welding of connecting rod front end has the tool bit, the tool bit surface sets to the pentagon structure, and the pentagon is structural to be four cutting blades, and two plane cutting edges set to the pentagon structure, do benefit to the different materials of cutting, and adaptability is wide, do benefit to the coping processing, the connecting rod front end is equipped with the interval groove of angle such as, connecting rod rear end center department is equipped with the clamping head, the surface of clamping head is equipped with plane and arc surface, angle interval distribution such as plane and arc surface is in the outside surface of clamping head.
Furthermore, the cutting blade is provided with a cross-shaped positioning at the vertex angle, so that the drilling positioning is facilitated.
Furthermore, the spacing grooves are provided with chamfering processing of the attached tool bits.
Compared with the prior art, the utility model has the advantages of:
(1) four cutting blades and two plane cutting blades of pentagon structure are set on the surface of the cutter head, so that the grinding treatment is convenient and the punching operation is facilitated.
(2) The cutting blade is provided with a cross-shaped positioning at the vertex angle, which is beneficial to positioning and installation.
(3) The surfaces of the clamping heads are provided with the planes and the arc surfaces which are distributed at intervals, so that the positioning and the installation are facilitated, the convenience and the stability of use can be greatly improved, and the high safety of punching is ensured.
