Abstract
An objective of the invention is to provide an inner-cooling stepped drill. The inner-cooling stepped drill comprises a drill handle and an edge portion. The edge portion is arranged at the end of the drill handle. A plurality of sections of spiral-shaped drilling blades, having gradually increased diameters, are sequentially arranged between the end of the edge portion and a connection portion which is arranged between the edge portion and the drill handle. A water inlet channel penetrates the drill handle. A cooling water outlet is formed in the end of the edge portion and communicated with the water inlet channel. A chip removing channel penetrates the drill handle. A chip removing outlet is formed in a connection position between each two adjacent drilling edge sections and communicated with the chip removing channel. Through reasonably arranged the chip removing outlets and the cooling water outlets, chips generated in drilling and cooling water are smoothly discharged from a discharging groove, thus the cooling water is guaranteed to flow out of the cooling water outlet smoothly to continuously cool the drill, cooling effect is guaranteed, and service life of the drill is prolonged.
Description
Technical field
The invention belongs to bit technique field, specially refer to a kind of interior cold step drill of good cooling results.
Background technology
Although traditional interior cold step drill is provided with the intake tunnel that runs through drillstock, and is provided with delivery port in the end of blade, thereby cooling water is entered from intake tunnel, from delivery port, flow out, for carrying out cooling in the position of boring.Therefore but because the blade of step drill is stepped, the cooling water and the chip that accumulate in boring are difficult to discharge, affected the effect of the cooling and boring of step drill.
Summary of the invention
The object of the invention is to propose a kind of interior cold step drill of good cooling results.
Interior cold brill of the present invention comprises drillstock and is arranged on the blade of drillstock end, the end of described blade to the joint of blade and drillstock is disposed with the some sections of boring swords that diameter increases gradually, described drillstock runs through and is provided with into aquaporin, and the end of described blade is provided with and the coolant outlet that enters aquaporin and communicate; Key is that described drillstock also runs through and is provided with channel of chip removal, and the joint of described adjacent two sections of boring swords is provided with the chip removal mouth communicating with described channel of chip removal.
In boring procedure, cooling water drains into the end of blade 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.Chip removal mouth is arranged to the joint of adjacent two sections of boring swords, can be by drill bit progradation, the larger boring sword of back segment diameter, to accumulating in the pressure of the cooling water of leading portion boring sword, is pressed into chip and cooling water in chip removal mouth, thereby improves the effect of chip removal and draining.For improving chip removal ability, channel of chip removal can be connected with a water pump.
Further, the joint chamfered transition of described adjacent two sections of boring swords, can avoid diameter sudden change because of adjacent two sections of boring swords to cause boring sword that diameter is larger and the active force between hole wall to increase suddenly like this, makes hole wall produce too much burr.
Interior cold step drill of the present invention is by the rational chip removal mouth of setting position and coolant outlet, 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 is the structural representation of interior cold step drill of the present invention.
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 interior cold step drill of the present embodiment comprises drillstock 1 and is arranged on the blade 2 of drillstock 1 end, the end of described blade 2 to blade 2 and the joint of drillstock 1 is disposed with the some sections of boring swords 3 that diameter increases gradually, described drillstock 1 runs through and is provided with into aquaporin-4, and the end of described blade 2 is provided with and the coolant outlet 5 that enters aquaporin-4 and communicate; Key is that described drillstock 1 also runs through and is provided with channel of chip removal 6, and the joint of described adjacent two sections of boring swords 3 is provided with the chip removal mouth 7 with described channel of chip removal 6.
In boring procedure, cooling water drains into the end of blade 2 from coolant outlet, and the chip that boring produces and the cooling water at drill bit place can drain into along chip removal mouth 7 places channel of chip removal 6, and discharge along channel of chip removal 6, thereby avoid accumulation of debris in boring and by coolant outlet 5 obstructions, cooling water can flow out from coolant outlet 5 all the time swimmingly like this, cooling to drill bit enforcement constantly, has guaranteed cooling effect.Chip removal mouth 7 is arranged to the joint of adjacent two sections of boring swords 3, can be by drill bit progradation, 3 pairs of the boring swords that back segment diameter is larger accumulate in the pressure of the cooling water at leading portion boring sword 3 places, chip and cooling water are pressed in chip removal mouth 7, thereby improve the effect of chip removal and draining.For improving chip removal ability, channel of chip removal 6 can be connected with a water pump.
The joint chamfered transition of adjacent two sections of boring swords 3, can avoid diameter sudden change because of adjacent two sections of boring swords 3 to cause boring sword 3 that diameter is larger and the active force between hole wall to increase suddenly like this, makes hole wall produce too much burr.
Claims (2)
1. cold step drill in a kind, comprise drillstock and the blade that is arranged on drillstock end, the end of described blade to the joint of blade and drillstock is disposed with the some sections of boring swords that diameter increases gradually, described drillstock runs through and is provided with into aquaporin, and the end of described blade is provided with and the coolant outlet that enters aquaporin and communicate; It is characterized in that described drillstock also runs through is provided with channel of chip removal, and the joint of described adjacent two sections of boring swords is provided with the chip removal mouth communicating with described channel of chip removal.
2. interior cold step drill according to claim 1, is characterized in that the joint chamfered transition of described adjacent two sections of boring swords.
