Abstract
The utility model provides an intercooling drill which is good in cooling effect. The intercooling drill comprises a drill shank and a blade portion which is arranged on the end portion of the drill shank, wherein the drill shank is provided with a water inlet channel in a communicated mode; the blade portion is provided with a chip discharging groove which is in a parabola shape along the axial direction; and the chip discharging groove is provided with a cooling water outlet which is communicated with the water inlet channel. The intercooling drill is characterized in that the cooling water outlet is inclined to the direction of the drill shank. According to the intercooling drill, the cooling water outlet with the reasonable position is formed to enable chips which are produced by drilling to be smoothly discharged out of the chip discharging groove, so that cooling water can always smoothly flow out of the cooling water outlet, cooling can be continuously performed on a drill bit, the cooling effect is ensured, and the service life of the drill bit is extended.
Description
Technical field
The utility model belongs to the bit technique field, specially refers to a kind of interior cold brill of good cooling results.
Background technology
Drill bit can discharge a large amount of heat in boring procedure, if can not in time cool off, might have influence on the 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 the drill bit cooling.But existing interior cold brill has only been realized cooling water is caused the drill bit place, does not consider but cooling water is flowed out from drill bit more glibly.The chip that produces in boring procedure might be blocked the outlet of cooling water, influences cooling effect.
The utility model content
The purpose of this utility model is the interior cold brill that proposes a kind of good cooling results.
Cold brill comprises drillstock and the blade that is installed in the drillstock end in of the present utility model, described drillstock runs through and is provided with into aquaporin, described blade offers parabola shaped chip area vertically, described discharge launder is provided with and goes into the coolant outlet that aquaporin communicates, and key is the oblique drillstock direction of described coolant outlet.
The oblique drillstock direction of coolant outlet, can be in boring procedure, push the chip that produces to the drillstock direction along discharge launder, thereby chip is discharged boring, avoid accumulation of debris boring in and coolant outlet is stopped up, cooling water can flow out from cooling off water out all the time swimmingly like this, constantly drill bit is implemented cooling, has guaranteed cooling effect.
Further, the both sides cell wall of described discharge launder is equipped with several coolant outlets, the coolant outlet of both sides cell wall is staggered, the staggered coolant outlet in cell wall both sides sprays cooling water simultaneously in discharge launder like this, can avoid accumulation of debris at the cell wall place of any side, influence chip and discharge.
Cold drilling through arranges suitable coolant outlet in of the present utility model, the chip that can successfully boring be produced is discharged in discharge launder, thereby guarantee that cooling water can flow out from cooling off water out all the time swimmingly, constantly drill bit is implemented cooling, guarantee cooling effect, prolonged the service life of drill bit.
Description of drawings
Fig. 1 is the structural representation of interior cold brill of the present utility model.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and operation principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, the interior cold brill of present embodiment comprises drillstock 1 and is installed in the blade 2 of drillstock 1 end, described drillstock 1 runs through and is provided with into aquaporin 3, described blade 2 offers parabola shaped chip area 4 vertically, described discharge launder 4 is provided with and goes into the coolant outlet 5 that aquaporin 3 communicates, key is the direction of described coolant outlet 5 oblique drillstocks 1, and the both sides cell wall of described discharge launder 4 is equipped with several coolant outlets 5, and the coolant outlet 5 of both sides cell wall is staggered.
Coolant outlet 5 oblique drillstock 1 directions can be in boring procedure, push the chip that produces to the drillstock direction along discharge launder 4, thereby chip is discharged boring, avoids accumulation of debris in boring and with coolant outlet 5 obstructions.And the staggered coolant outlet in cell wall both sides 5 ejection cooling waters in the discharge launder 4 simultaneously, can avoid accumulation of debris at the cell wall place of any side, influence the chip discharge.Cooling water can flow out from cooling off water out all the time swimmingly like this, constantly drill bit is implemented cooling, has guaranteed cooling effect.
Claims (2)
1. cold brill in a kind, comprise drillstock and the blade that is installed in the drillstock end, described drillstock runs through and is provided with into aquaporin, described blade offers parabola shaped chip area vertically, described discharge launder is provided with and goes into the coolant outlet that aquaporin communicates, and it is characterized in that the oblique drillstock direction of described coolant outlet.
