Abstract
The utility model relates to an internal-cooling drill bit comprising a cutter handle and a cutter edge, wherein the cutter edge is arranged at the front end of the cutter handle; the rear end of the cutter handle is provided with a clamping groove; a coolant through hole runs through a transverse central line of the cutter handle; and a filtering net is arranged in the coolant through hole at the front end of the cutter handle. The coolant through hole of the internal-cooling drill bit is not blocked easily. In the internal-cooling drill bit, the cooling effect is good the service life is long.
Description
Technical field
The utility model relates to a kind of drill bit, specifically, relates to a kind of interior cold drill bit.
Background technology
Existing drill bit is provided with cooling passage in order to increase cooling effect in handle of a knife, increase the film-cooled heat of cooling fluid.Because in the drilling cuttings process, chisel edge portion can produce a large amount of chips, and these chips are easy to enter in the cooling passage, stop up cooling passage, make cooling fluid to circulate, cause cooling failure, cause the drill bit high-temperature operation, bring serious accident.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
The utility model content
The purpose of this utility model provides a kind of not susceptible to plugging interior cold drill bit.
The technical solution adopted in the utility model is:
Cold drill bit in a kind of comprises handle of a knife and blade, and described blade is arranged on the front end of handle of a knife, and described handle of a knife rear end is provided with draw-in groove, runs through cross central line on the described handle of a knife and has the cooling fluid through hole, is provided with screen pack in the cooling fluid through hole of described handle of a knife front end.
Described screen pack is detachable screen pack.
The aperture of described screen pack is 1-2mm.
The utility model is provided with screen pack in the cooling fluid through hole of handle of a knife front end, this screen pack can stop chip to enter in the cooling fluid through hole effectively, has avoided the obstruction of chip to the cooling fluid through hole.
The utility model has the advantages that: the cooling fluid through hole is difficult for stopping up.Good cooling results, long service life.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is a side view of the present utility model.
Wherein: 1, handle of a knife, 2, blade, 3, draw-in groove, 4, the cooling fluid through hole, 5, screen pack.
The specific embodiment
As shown in Figures 1 and 2, cold drill bit in a kind of, comprise handle of a knife 1 and blade 2, blade 2 is arranged on the front end of handle of a knife 1, handle of a knife 1 rear end is provided with draw-in groove 3, runs through cross central line on the handle of a knife 1 and has cooling fluid through hole 4, is provided with screen pack 5 in the cooling fluid through hole 4 of handle of a knife 1 front end, this screen pack 5 can stop chip to enter in the cooling fluid through hole 4 effectively, has avoided the obstruction of chip to cooling fluid through hole 4.Clean for the ease of screen pack 5, screen pack 5 is designed to detachable, in order reasonably to increase the flow of cooling fluid, with the limited aperture of screen pack 5 in the 1-2mm scope.
