Abstract
The invention aims to provide an internally cooled drill with an automatic chip removal function. The internally cooled drill comprises a drill shank and an edge portion. The edge portion is mounted at an end of the drill shank. The internally cooled drill is characterized in that the drill shank is penetratingly provided with a water inlet channel and a chip removal channel, a parabolic chip groove is axially formed in the edge portion, a cooling water outlet and a chip removal opening are formed in the chip groove, the cooling water outlet is communicated with the water inlet channel, and the chip removal opening is communicated with the chip removal channel. The internally cooled drill with the automatic chip removal function has the advantage that good cooling effects can be realized; the chip removal opening and the cooling water outlet are formed in the internally cooled drill, so that chips generated during hole drilling can be smoothly discharged from the chip groove, cooling water generated during hole drilling can be smoothly drained from the chip groove, cooling water can assuredly smoothly flow out from the cooling water outlet all along, a drill bit can be continuously cooled by the cooling water, the cooling effects can be guaranteed, and the service life of the drill bit can be prolonged.
Description
Technical field
The invention belongs to bit technique field, specially refer to a kind of cold brill in chip removal of good cooling results.
Background technology
Drill bit can discharge a large amount of heat in boring procedure, if can not be cooling in time, likely can have influence on boring effect, even can damage drill bit.Interior cold brill can be introduced cooling water to the front end of drill bit from drillstock, thereby can in the process of boring, be drill bit cooling.But existing interior cold brill has only been realized cooling water has been caused to drill bit place, does not but consider and how to make cooling water flow out from drill bit more glibly.The chip producing in boring procedure is likely blocked the outlet of cooling water, affects cooling effect.
Summary of the invention
The object of the invention is to propose a kind of cold brill in chip removal of good cooling results.
Interior cold brill of the present invention comprises drillstock and is arranged on the blade of drillstock end, key is that described drillstock runs through and is provided with into aquaporin and channel of chip removal, described blade offers parabola shaped chip area vertically, and described discharge launder is provided with and enters the coolant outlet that aquaporin communicates and the chip removal mouth communicating with described channel of chip removal.
In boring procedure, cooling water drains into drill bit place from coolant outlet, and the chip that boring produces and the cooling water at drill bit place can drain into along chip removal mouth place channel of chip removal, and discharge along channel of chip removal, thereby avoid accumulation of debris boring in and coolant outlet is stopped up, cooling water can flow out from coolant outlet all the time swimmingly like this, cooling to drill bit enforcement constantly, has guaranteed cooling effect.For improving chip removal ability, channel of chip removal can be connected with a water pump.
Further, described coolant outlet and chip removal mouth are separately positioned on the both sides cell wall of discharge launder, and described chip removal mouth is arranged at the cell wall of the boring direction towards drill bit of discharge launder.The strength that can rotate by drill bit is like this pushed chip to chip removal mouth, improves chip removal ability.
Of the present invention in chip removal cold drilling through chip removal mouth and coolant outlet are set, chip and the cooling water that can successfully boring be produced are discharged in discharge launder, thereby guarantee that cooling water can flow out from coolant outlet all the time swimmingly, to drill bit, implement cooling constantly, guarantee cooling effect, extended the service life of drill bit.
Accompanying drawing explanation
Fig. 1 be of the present invention in chip removal the structural representation of cold brill.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail as the effect of the mutual alignment between the shape of each related member, structure, each several part and annexation, each several part and operation principle etc.
Embodiment 1:
As shown in Figure 1, the cold brill in chip removal of the present embodiment comprises drillstock 1 and is arranged on the blade 2 of drillstock 1 end, key is that described drillstock 1 runs through and is provided with into aquaporin 3 and channel of chip removal 4, described blade offers parabola shaped chip area 5 vertically, and described discharge launder 5 is provided with and enters the coolant outlet 6 that aquaporin 3 communicates and the chip removal mouth 7 communicating with described channel of chip removal 4.Wherein coolant outlet 6 and chip removal mouth 7 are separately positioned on the both sides cell wall of discharge launder 5, and described chip removal mouth 7 is arranged at the cell wall of the boring direction towards drill bit of discharge launder 5.
In boring procedure, cooling water drains into drill bit place from coolant outlet 6, and the cooling water at the chip that boring produces and drill bit place can drain into channel of chip removal 4 in eye chip removal mouth 7 places, and discharge along channel of chip removal 4, thereby avoid accumulation of debris in boring and by coolant outlet 6 obstructions, cooling water can flow out from coolant outlet 6 all the time swimmingly like this, cooling to drill bit enforcement constantly, has guaranteed cooling effect.And because chip removal mouth 7 is arranged at the cell wall of the boring direction towards drill bit of discharge launder 5, the strength that can rotate by drill bit be pushed chip to chip removal mouth 7, further improves chip removal ability.Certainly, channel of chip removal can also be connected with a water pump, further to improve chip removal ability.
Claims (2)
1. a cold brill in chip removal, comprise drillstock and the blade that is arranged on drillstock end, it is characterized in that described drillstock runs through is provided with into aquaporin and channel of chip removal, described blade offers parabola shaped chip area vertically, and described discharge launder is provided with and enters the coolant outlet that aquaporin communicates and the chip removal mouth communicating with described channel of chip removal.
According to claim 1 in chip removal cold brill, it is characterized in that described coolant outlet and chip removal mouth are separately positioned on the both sides cell wall of discharge launder, and described chip removal mouth is arranged at the cell wall of the boring direction towards drill bit of discharge launder.
