Abstract
The utility model discloses a kind of electric punch drill bit cutter head, it is protruding that this cutter head is formed with several pinnacles on the end face of tubular structure free end, the operation of putting the first edge on a knife or a pair of scissors before avoiding use, the medial surface of this external cutter head offers the first vertical chip removal and founds groove, the second scrap chute of inclination is offered at cutter head lateral surface, the scrap that cutter head is produced in drilling process is discharged automatically, and the situation of blocking can not be there is, avoid in drilling process and stop repeatedly to the situation that hole is cleared up, greatly improve rate of penetration, and saved time and cost of labor.
Description
Technical field
The utility model relates to a kind of electric punch instrument, particularly relates to a kind of electric punch drill bit cutter head, belongs to grooved bit part field.
Background technology
In currently available technology, plane in one bottom the cutter head of known grooved bit, usually need before use to use emery wheel or other article to put the first edge on a knife or a pair of scissors to cutter head, very inconvenient when urgent need; In addition two sides of the cutter head of existing grooved bit are all without chip area, cannot chip removal in the process that drill bit creeps into, and need repeatedly to stop to carry out cleaning to hole and could continue to creep into; Or be provided with chip area in an only side of existing grooved bit cutter head, but this kind of one side chip area be arranged on actual use time chip removal function unsatisfactory, chip still can block cutter head in drilling process, still repeatedly need stop in drilling process and clear up, otherwise very easily block, this just causes the use inconvenience of drill bit, and cleaning is wasted time and energy.
Utility model content
In order to overcome above-mentioned technological deficiency, the utility model provides a kind of electric punch drill bit cutter head, this cutter head without the need to putting the first edge on a knife or a pair of scissors, and automatically can carry out good chip removal in drilling process, and solving cannot chip removal and the susceptible to plugging problem of appearance in drilling process in prior art.
The utility model in order to solve the problems of the technologies described above adopted technical scheme is:
A kind of electric punch drill bit cutter head, location is fixedly arranged on the drilling rod of grooved bit, described cutter head is a tubular structure, one end of this tubular structure is located by connecting on described drilling rod, the other end of this tubular structure is free end, the end face of described free end is formed with several projections in waves, and the madial wall of this tubular structure offers some spaced first chip areas, the lateral wall of this tubular structure offers some spaced second chip areas.
Its further technical scheme is:
Described first chip area extends to bottom cutter head from the end face of tubular structure free end, and the centerline axis parallel of this first chip area and tubular structure.
Described second chip area extends to bottom cutter head from the end face of tubular structure free end, and the central axis of this second chip area and tubular structure has angle.
Described protruding uniform intervals is fixedly arranged on the end face of the free end of tubular structure.
The longitudinal cross-section of described projection is triangular in shape, and this leg-of-mutton base overlaps with the end face of free end.
Advantageous Effects of the present utility model is: it is protruding that this cutter head is formed with several pinnacles on the end face of tubular structure free end, the operation of putting the first edge on a knife or a pair of scissors before avoiding use, the medial surface of this external cutter head offers the first vertical chip removal and founds groove, the second scrap chute of inclination is offered at cutter head lateral surface, the scrap that cutter head is produced in drilling process is discharged automatically, and the situation of blocking can not be there is, avoid in drilling process and stop repeatedly to the situation that hole is cleared up, greatly improve rate of penetration, and save time and cost of labor.

Detailed description of the invention
Composition graphs 1 to Fig. 3 is described in further detail the utility model.
A kind of electric punch drill bit cutter head, location is fixedly arranged on the drilling rod of grooved bit, described cutter head 1 is in a tubular structure, one end of this tubular structure is located by connecting on described drilling rod, the other end of this tubular structure is free end 2, the end face of described free end is formed with several projections 3 in waves, and the madial wall 4 of this tubular structure offers some spaced first chip areas 5, the lateral wall 6 of this tubular structure offers some spaced second chip areas 7.
Described first chip area 5 extends to bottom cutter head from the end face of tubular structure free end, and the centerline axis parallel of this first chip area and tubular structure, first chip area 5 is positioned on cutter head tubular structure madial wall, and it is that the recessed structures of vertical state is convenient to cutter head in drilling process, is got rid of inner scrap.
Described second chip area 7 extends to bottom cutter head from the end face of tubular structure free end, and the central axis of this second chip area and tubular structure has angle, second chip area 7 is positioned on cutter head tubular structure lateral wall, and it is convenient in the recessed structures tilted the scrap that cutter head discharges outside in drilling process.
Described protruding 3 uniform intervals are fixedly arranged on the end face of free end 2 of tubular structure.The longitudinal cross-section of protruding 3 is triangular in shape, and this leg-of-mutton base overlaps with the end face of free end, and the top of this projection 3 is pinnacle, makes this cutter head not need before use to do any process of putting the first edge on a knife or a pair of scissors, can directly use.
