Abstract
The utility model is in the prior art, diamond bit is in drilling glass process because cooling water supply is insufficient, arrange powder not in time, the high cutting heat generated is easy to burn out drill bit, the problem of influencing glass quality, provides a kind of new structural diamond bit, since the drill bit cutting end is provided with annular abrasive layer, the chip-removal hole provided circumferentially about of abrasive material, around the axis of abrasive material, helically type is arranged chip-removal hole, screw type chip-removal hole can reduce cutting resistance, the discharge of powder easy to process, chip-removal hole penetrates abrasive material, communicate with the outside world the inner cavity of abrasive material, after injecting cooling water, processing powder can be discharged with cooling water by chip-removal hole, cutting heat can be reduced rapidly, diamond bit is avoided to burn out, extend the service life of diamond bit, improve the processing quality of work piece.
Description
Technical field
The utility model relates to a kind of new structural diamond bits.
Background technique
Diamond bit is mainly used for drilling vehicle glass, and vehicle glass thickness is generally 3.2-6.0mm.Due to drill bit
It is to work under high speed rotation, and drilling gap very little between drill bit and glass, when operation is easy to generate cutting heat.In cooling
Drill bit cooling can be made bad when water supply is insufficient, not in time, the high cutting heat moment of generation can burn drill bit row's powder.Buddha's warrior attendant
Aiguille and vehicle glass can be generated quality problems by cutting heat affecting.Diamond bit is in the cooling undesirable feelings of high cutting heat
Under condition, abrasive material carcass becomes blue or brown, diamond carbonization occurs, the mechanical performance of diamond bit is reduced, when serious
It will cause the case where diamond abrasive layer carcass falls off.Occur burning side, chip, sliver to cause to be processed product vehicle glass
Quality risk.
Utility model content
The purpose of this utility model is that, in the prior art, diamond bit is in drilling glass process because cooling
Water supply is insufficient, and not in time, the high cutting heat of generation is easy to provide the problem of burning out drill bit, influence glass quality a kind of new row's powder
The diamond bit of type structure.
The purpose of this utility model is achieved through the following technical solutions:
The one of knife handle is arranged in a kind of new structural diamond bit, cutter head and knife handle including coaxial arrangement, cutter head
End, cutter head cutting end are provided with annular abrasive layer, the chip-removal hole provided circumferentially about of abrasive material, and chip-removal hole surrounds the axis of abrasive material
Helically type is arranged；
The abrasive material is in stepped ramp type, the inclined face of shoulder；
The helix of the chip-removal hole is in 60 degree of lift angles；
The chip-removal hole is by abrasive material cutting end end to abrasive material shoulder；
The chip-removal hole is arranged to three, and the same rotation direction of three chip-removal holes is evenly distributed on abrasive material；
The diamond bit further includes cooling water injection hole, and cooling water injection hole penetrates axle center and the chip-removal hole of cutter head and knife handle
It communicates.
Using a kind of new structural diamond bit provided by the utility model, due to the end of drill bit annular abrasive layer
Provided with screw type chip-removal hole, chip-removal hole penetrates abrasive material, communicates with the outside world the inner cavity of abrasive material.Screw type chip-removal hole can be with
Reduce cutting resistance, the discharge of powder easy to process avoids diamond bit from burning out, prolongs so as to quickly reduce cutting heat
The service life of long diamond bit improves the processing quality of work piece.

Specific embodiment
The utility model is further described through combined with specific embodiments below:
As shown in Figure 1 to Figure 3, the utility model provides a kind of new structural diamond bit, the diamond bit packet
The cutter head 1 and knife handle 5 of coaxial arrangement are included, cutter head 1 is connected to one end of knife handle 5.Knife handle 5 is used for connecting cutting apparatus, cutter head 1
In cutting work piece.Cutting end is provided with annular abrasive layer 2 on cutter head 1.The excircle of abrasive material 2 can be cylinder,
Can be in stepped ramp type, the end abrasive material outer diameter above step is less than the root abrasive material outer diameter below step, step surface be to
The inclined inclined surface of path step.
Screw type chip-removal hole 3 is set on abrasive material 2, and the inner cavity of abrasive material 2 is communicated with the outside world by chip-removal hole 3, chip removal
Hole 3 is arranged along the axis of annular abrasive layer.Rotation status is in when due to bit operation, screw type chip-removal hole can reduce drill bit
Cutting resistance, while be conducive to cut powder discharge.Chip-removal hole 3 can be by end to the root of abrasive material 2, still, this
Scheme will affect drill bit intensity.Preferred embodiment is chip-removal hole 3 by the end of abrasive material 2 to 2 shoulder of abrasive material.Chip-removal hole 3 is preferred
It is arranged to three, three same rotation directions of chip-removal hole 3 are evenly distributed on the circumference of abrasive material 2, and the width of chip-removal hole 3 is preferably
1.5mm.The helical angle of chip-removal hole 3 is preferably 60 degree.
Preferentially, axial cooling water injection hole 4 is set on cutter head 1 and knife handle 5, and cooling water injection hole 4 penetrates cutter head 1 and knife handle
5.The free end of knife handle 5 is arranged in the water injection end of cooling water injection hole 4, and water outlet is communicated with the inner cavity of drill bit abrasive material 2.Due to mill
The inner cavity of the bed of material 2 is communicated with the outside world by chip-removal hole 3, so, cooling water can enter abrasive material 2 along cooling water injection hole 4
Inner cavity is simultaneously overflowed from chip-removal hole 3, so that processing the powder of generation can be discharged with cooling water.
In addition, the circular hole in bit cutting glass, using the lesser part of 2 outer end diameter of abrasive material to glass cutting out
For cylindrical circular hole.But it sometimes according to the technological requirements, needs to process buried via hole on glass, is suitable for the installation of fixing piece,
At this time, it may be necessary to continue to process the buried via hole suitable for installation to bore edges using the step surface of abrasive material 2.
