Abstract

The invention relates to an automatic-water-feeding cooling twist drill. Existing domestic twist drills are respectively of an external cooling type structure, so that the cutting temperature is high, scraps are not discharged smoothly, abrasion of drill bits is fast, the requirement for improvement of the drilling and cutting speed of a numerical control machine tool, a machining center and the like can not be satisfied, and the work efficiency is low. The automatic-water-feeding cooling twist drill comprises a drill handle (1). The drill handle is connected with a drill body (2). A radial through hole (3) is formed in the drill body. An axial through hole (4) is formed in the drill handle and communicated with the radial through hole. Two parallel spiral holes (5) are formed in the drill body and communicated with the radial through hole. The axial through hole is connected with a water inlet pipe (6). The water inlet pipe is connected with a pump (7). The pump is connected with a water tank (9) through a flow controller (8). The automatic-water-feeding cooling twist drill serves as a drilling and cutting tool.

Description

The cooling fluted drill of self water feeding
Technical field
The present invention relates to a kind of drilling cutters, be specifically related to the cooling fluted drill of a kind of self water feeding.
Background technology
At present domestic existing fluted drill is external-cooling type structure, causes cutting temperature high, and chip removal is not smooth, and bit wear is fast, and very limited of the life-span that causes cutter, even if the lubricant of practical oil-containing or to smear certain layer effect at tool surface also not obvious.The cooling and lubricating effect of cutting fluid is poor, often causes the embrittlement of drill bit, has reduced the durability of drill bit, makes the application of carbide drill be subject to certain limitation; Because feedwater is insufficient, make drilling speed be subject to certain limitation simultaneously, can not meet the requirement that Digit Control Machine Tool, machining center etc. improve drilling speed, inefficiency.
Summary of the invention
The object of the invention is provides a kind of self water feeding cooling fluted drill for the problem of above-mentioned existence, and during cutting, cooling fluid reaches cutting point and cutting region carried out fully cooling by automatically reaching, and improves stock-removing efficiency, and bit life is increased substantially.
Above-mentioned object realizes by following technical scheme:
The cooling fluted drill of self water feeding, comprise drillstock, described drillstock connects drill body, on described drill body, there is a radial direction through hole, on described drillstock, have axially extending bore and be communicated with described radial direction through hole, have two parallel spiral-shaped orifices and be communicated with described radial direction through hole on described drill body, described axially extending bore connects water inlet pipe, described water inlet pipe connects pump, and described pump connects water tank by flow controller.
The cooling fluted drill of described self water feeding, described radial direction through hole is positioned at the position apart from point of a knife 135mm, and the diameter of described radial direction through hole is 5mm.
Beneficial effect:
1. the present invention arranges axially extending bore on drillstock, two parallel spiral shape holes and radial direction through hole are set on drill body, Shi San hole connects, heat the techniques such as the system of turning round and form Cooling Holes fluted drill in spirality, this structural design makes cooling fluid or lubricating fluid in cooling procedure, not only can be entered by the radial direction through hole of drill body drill body and can directly enter from afterbody axially extending bore, the drillstock of flowing through enters the effect that threaded hole reaches cooling and lubricating, and cooling fluid can supply with automatically, easy to operate.
2. fluted drill drill bit material provided by the invention is carbide alloy, when processing work because cooling fluid can directly be delivered directly to cutting region by the axially extending bore on drillstock by drillstock afterbody, make cooling abundant and easy to operate, reduce cutting edge wearing and tearing, therefore tool flank wear is less than common fluted drill, thereby obviously improved the life-span of drill bit, than common fluted drill, improved 3-4 doubly.When cooling fluid flows out, contribute to chip removal, improved operating efficiency.
Accompanying drawing explanation
Fig. 1, plan structure schematic diagram of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention.
Embodiment 1:
As shown in Figure 1: the cooling fluted drill of self water feeding of the present invention, comprise drillstock 1, described drillstock connects drill body 2, on described drill body, there is a radial direction through hole 3, on described drillstock, have axially extending bore 4 and be communicated with described radial direction through hole, have two parallel spiral-shaped orifices 5 and be communicated with described radial direction through hole on described drill body, described axially extending bore connects water inlet pipe 6, described water inlet pipe connects pump 7, and described pump connects water tank 9 by flow controller 8.
Embodiment 2:
The cooling fluted drill of described self water feeding, described radial direction through hole is positioned at the position apart from point of a knife 135mm, and the diameter of described radial direction through hole is 5mm.

Claims (2)
