Abstract
A kind of slotting drill bit, relate to a kind of drill bit, described drill bit comprises drill bit shaft (1), mill bar (2), cutting blade (3), hole slot (4), hole slot passage (5), drill bit shaft (1) bottom is connected with mill bar (2), mill bar (2) bottom connects cutting blade (3), mill bar (2) has strip hole slot (4) in circular one week, cutting blade (3) has hole slot passage (5) in the inner circle of mill bar, cutting blade (3) correspondence position has hole slot (4) in one week on the cylindrical of outer, hole slot on mill bar, hole slot passage on cutting blade and the hole slot on cutting blade are on the same line.Described hole slot (4) is longitudinally strip, and hole slot cross section is 5-15 ° of angle with mill bar and the outer tangent line circumferentially of cutting blade.Lubricant, by being shaped with hole slot on mill bar and cutting blade, can import when realizing cutting operation by this drill bit, improves cutting efficiency, improves the service life of drill bit simultaneously.
Description
Technical field
The utility model relates to a kind of drill bit, particularly relates to a kind of slotting drill bit.
Background technology
Drill bit is conventional fluting or boring bar tool, at present conventional on the market drill bit has drilling hole type and shaped grooved etc., shaped grooved drill bit is used for slotting to base material, such as slot at building and ornament materials plate back, body of wall is fixed on for connecting connector, this drill bit is made up of mill bar and circular cutting blade usually, but common slotting drill bit is owing to running up, due to frictional force effect during cutting base material, wearing and tearing are larger on the one hand, easy by substrate damage on the other hand, reduce service life and the cutting efficiency of drill bit.
Utility model content
The purpose of this utility model is to provide a kind of slotting drill bit, by being shaped with hole slot on mill bar and cutting blade, lubricant can be imported when realizing cutting operation, improves cutting efficiency, improves the service life of drill bit simultaneously.
The purpose of this utility model is achieved through the following technical solutions:
A kind of slotting drill bit, described drill bit comprises drill bit shaft, mill bar, cutting blade, hole slot, hole slot passage, mill bar is connected with bottom drill bit shaft, cutting blade is connected bottom mill bar, mill bar circle has strip hole slot in one week, cutting blade has hole slot passage in the inner circle of mill bar, and cutting blade correspondence position had hole slot in one week on the cylindrical of outer, and hole slot, the hole slot passage on cutting blade and the hole slot on cutting blade on mill bar are on the same line.
Described a kind of slotting drill bit, hole slot described in it is longitudinally strip, and hole slot cross section is 5-15 ° of angle with the outer tangent line circumferentially of mill bar and cutting blade.
Described a kind of slotting drill bit, hole slot described in it and hole slot passage offer 1-15 for one week along mill bar and cutting blade.
Advantage of the present utility model and effect are:
1, the utility model by offering the consistent hole slot in direction and hole slot passage on mill bar and cutting blade, can when cutting operation by lubricant as water etc. sends into rubbing surface, play cooling effect while reducing frictional force.Or do not add lubricant, increase the air passage rates of cut surface, improve cutting efficiency.
2, the utility model slotting drill bit has cutting speed soon, and wear-resistant, long service life a little.
3, the utility model slotting drill bit production cost is low, high efficiency, and applicable industrialization is upper on a large scale produces.
Accompanying drawing explanation
Fig. 1 is the front view of the utility model adjustable connecting piece;
Fig. 2 is the top view of the utility model adjustable connecting piece.
Detailed description of the invention
Below in conjunction with Figure of description Fig. 1 to Fig. 2, the utility model is described in further details.
Annex in figure: 1 is drill bit shaft, 2 is mill bar, and 3 is cutting blade, and 4 is hole slot, 5 hole slot passages.
As depicted in figs. 1 and 2, the utility model is a kind of slotting drill bit.Drill bit diamond used, metal or macromolecular material are made.The utility model slotting drill bit comprises drill bit shaft 1, mill bar 2, cutting blade 3, hole slot 4, hole slot passage 5.Drill bit shaft 1 bottom welding or die casting have mill bar 2, and mill bar 2 bottom welding or die casting have cutting blade 3, and the circle of mill bar 2 opens several for one week hole slot 4, and this hole slot is upper and lower standard-sized sheet form.Cutting blade 3 has hole slot passage 5 in the inner circle of mill bar with on mill rod aperture groove correspondence position, and this hole slot passage is only top and has strip passage, and bottom is shut.The cylindrical of cutting blade 3 near outer above and on hole slot passage correspondence position has hole slot 4 in one week, and hole slot, the hole slot passage on cutting blade and the hole slot on cutting blade on mill bar are on the same line.Hole slot 4 be longitudinally strip, and hole slot cross section and mill bar and cutting blade outward tangent line circumferentially at an angle, are generally 5-15 ° of angle.Hole slot and hole slot passage can offer several in one week according to actual needs along mill bar and cutting blade.Hole slot passage on cutting blade and hole slot length ratio can change according to actual needs.
During site operation, drill bit shaft is inserted on electric drilling, switch on power, cutting blade high-speed rotation, cutting operation is carried out to base material.Water or other lubricants can be sent on cut surface along hole slot and hole slot passage during cutting operation, reduce friction, the temperature of cutting blade and cut surface while increasing lubricant effect, can be reduced.Or do not add water or other lubricants, directly carry out cutting operation, increase the air flowing of the scope of operation.Due to hole slot and cut surface at an angle, scrap can be taken out of, improve the service life of improving drill bit while efficiency of construction.
Claims (3)
1. a slotting drill bit, it is characterized in that, described drill bit comprises drill bit shaft (1), mill bar (2), cutting blade (3), hole slot (4), hole slot passage (5), drill bit shaft (1) bottom is connected with mill bar (2), mill bar (2) bottom connects cutting blade (3), mill bar (2) has strip hole slot (4) in circular one week, cutting blade (3) has hole slot passage (5) in the inner circle of mill bar, cutting blade (3) correspondence position has hole slot (4) in one week on the cylindrical of outer, hole slot on mill bar, hole slot passage on cutting blade and the hole slot on cutting blade are on the same line.
