Abstract
The utility model discloses a lengthened hard alloy spiral supper hole cutter. The lengthened hard alloy spiral supper hole cutter comprises a cutter body and a cutter handle. The cutter body comprises a cutter bar and a drilling portion. The drilling portion is provided with a plurality of spiral chip grooves. A drill point portion which protrudes axially is arranged at the center of the end face of the top of the drilling portion. Round cutting edges are evenly distributed on the end face of the top and the edge of the top of the drilling portion with the drill point portion as the center of a circle. According to the lengthened hard alloy spiral supper hole cutter, due to the facts that the cutter body is composed of the cutter bar and the drilling portion, the drilling portion is provided with the drill point portion, and the round cutting edges are distributed on the periphery of the drilling portion, a wall is cut in a multi-layer mode, the effects of stable opening and good concentricity are achieved through integrated feeding, the drilling accuracy is improved, the drilling working face is enlarged, and the work efficiency is improved. Compared with the prior art, the lengthened hard alloy spiral supper hole cutter further has the advantages of being simple in structure and low in manufacturing cost. The lengthened hard alloy spiral supper hole cutter can be used for drilling holes in the wall when an air conditioner, a smoke exhaust ventilator and the like are installed, the diameter of each machined hole ranges from 25 mm to 110 mm, and the machining depth ranges from 280 mm to 1100 mm.
Description
[technical field]
The utility model relates to boring bar tool technical field, particularly a kind of hard alloy screw super hole cutter that lengthens.
[background technology]
At present domestic installing an air-conditioner, the drill bit that need to punch on metope such as smoke exhaust ventilator or the finishing of living in peace generally comprises cutter hub and handle of a knife, cutter hub and handle of a knife link into an integrated entity, because the cutter hub of this device is vertical bar type, can cause when punching drill bit to be offset, the hole of getting be not justify very much and centering poor, some even can produce and destroy metope, and apex point is easy to wear, working (machining) efficiency is low, and at present wall opening apparatus length is not on the market very long, is difficult to meet the need of market.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of hard alloy screw super hole cutter that lengthens, and can improve the boring degree of accuracy, expands perforate working face, increases work efficiency, and prevents from damaging, and increases the service life.
For achieving the above object, the utility model proposes a kind of hard alloy screw super hole cutter that lengthens, comprise cutter hub and handle of a knife, described cutter hub is connected with handle of a knife and is one-body molded, described cutter hub comprises knife bar and drilling portion, in described drilling portion, be provided with some helical flutes, the center of the top end face of drilling portion is provided with axial raised apex point portion, on the top end face of drilling portion and edge, is evenly distributed with circular cutting edge taking apex point portion as the center of circle.
As preferably, described apex point portion is V-type location apex point.
As preferably, in described drilling portion, offer groove, described circular bite is fixedly mounted in described groove.
As preferably, described circular cutting edge and drilling portion are welded and fixed.
As preferably, described cutter hub adopts tapering to be connected with handle of a knife.
The beneficial effects of the utility model: the utility model knife bar is by forming cutter hub by knife bar and drilling portion, the distribute mode of multiple circular cutting edge of apex point portion and surrounding that arranges in drilling portion is cut at many levels to body of wall, directly promoting comprehensively, it is steady to have realized opening, the effect of good concentricity, improve the boring degree of accuracy, expand perforate working face, thereby increase work efficiency, compared with prior art, the utility model also has simple in structure, the advantage of low cost of manufacture, can be used for installing an air-conditioner, the use that smoke exhaust ventilator etc. need to punch on metope, realize the aperture processing between processing pore diameter range 25-110mm size, working depth can be in 280-1100mm scope.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
[brief description of the drawings]
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model.
In figure: 1-cutter hub, 2-handle of a knife, 3-knife bar, 4-drilling portion, 5-helical flute, 6-apex point portion, 7-circular cutting edge, 8-groove.
[detailed description of the invention]
Consult Fig. 1 and Fig. 2, the utility model comprises cutter hub 1 and handle of a knife 2, described cutter hub 1 is connected with handle of a knife 2 and is one-body molded, described cutter hub 1 comprises knife bar 3 and drilling portion 4, in described drilling portion 4, be provided with some helical flutes 5, the center of the top end face of drilling portion 4 is provided with axial raised apex point portion 6, on the top end face of drilling portion 4 and edge, be evenly distributed with circular cutting edge 7 taking apex point portion 6 as the center of circle, described apex point portion 6 is V-type location apex point, in described drilling portion 4, offer groove 8, described circular bite 7 is fixedly mounted in described groove 8, described circular cutting edge 7 is welded and fixed with drilling portion 4, described cutter hub 1 adopts tapering to be connected with handle of a knife 2.
Operation principle of the present utility model: the utility model knife bar is by forming cutter hub by knife bar 3 and drilling portion 4, some helical flutes 5 are set in drilling portion 4, can not only in the time of deep hole processing, discharge swimmingly bits dirt, can also reach the effect of heat radiation, improve the service life of drill bit, on the top end face of drilling portion 4 and edge, be evenly distributed with circular cutting edge 7 taking apex point portion 6 as the center of circle, by changing the position of circular cutting edge 7, make it to have expanded the working face of perforate in the situation that impacting rotation, realize one-time formed object, because apex point portion 6 is V-type location apex point, by means of the centering location of V-type location apex point, when punching, drill bit can not be offset, the Kong Jiyuan getting again can centering, can metope not produced and be destroyed, and the utility model is cut at many levels to body of wall in the mode of V-type location apex point and circular cutting edge, directly promoting comprehensively, it is steady to have realized opening, the effect of good concentricity, improve the boring degree of accuracy, thereby increase work efficiency, V-type location apex point 5 and circular cutting edge 4 all adopt Hardmetal materials to be welded on cutter hub by money base or copper base, can improve the service life of drill bit, cutter hub 1 is connected by employing tapering with handle of a knife 2, can ensure in the situation that drill bit entirety is lengthened to 1.2 meters of length, to also have enough intensity, compared with prior art, the utility model also has simple in structure, the advantage of low cost of manufacture, can be used for installing an air-conditioner, the use that smoke exhaust ventilator etc. need to punch on metope.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
