Abstract
A kind of glass perforating drill with chamfering, including drill main body, the drill main body lower section is provided with chamfering device, and the chamfering device lower end is provided with drilling, the drilling external diameter is less than drill main body bottom external diameter, and the drilling upper end is peripheral to form chamfering inclined-plane with drill main body bottom periphery.The beneficial effects of the utility model are：（1）The utility model drill main body and chamfering device be integral type structure, it is to avoid connects situation loosely during punching between drill main body and chamfering device；（2）Phenomenon of the glass orifice that the drill bit is got without chip；（3）Using the drill bit to glass punching after, glass is also easy to from the mesopore of drill bit out, improve operating efficiency.
Description
Technical field
The utility model is specifically related to a kind of glass perforating drill with chamfering.
Background technology
During existing glass punching, in order that it is not sharp at glass angled, increase its accessible property, or in order to remove
Because of the burr of processing generation and for the ease of component assembly on part, often all chamfering can be made in bore ends.Chamfering is generally
45 °, it is also possible to as 30 ° or 60 °, when needing chamfering due to existing glass punching, drill bit and chamfering device can be respectively used, this
Can cause that the hole chip for typing it out, than more serious, occurs phenomenon loosely when chamfering device is connected with drill bit if sample, while falling
The non-round of the wall top of drill bit can be caused the phenomenon that glass can't get out, in chamfering by angle device when being screwed when being connected with drill bit
Need workman to shut down afterwards again to take out glass, cause low production efficiency.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, there is provided a kind of glass punching with chamfering
Drill bit, there is chamfering device on the drill bit, punching realizes chamfering simultaneously, and the device drill bit and chamfering device after sintering are one
Body formula, so avoiding the phenomenon that glass after chamfering can't get out.
In order to solve the above technical problems, the technical solution of the utility model is：
A kind of glass perforating drill with chamfering, including drill main body, the drill main body lower section are provided with chamfering device, institute
State chamfering device lower end and be provided with drilling, the drilling external diameter is less than drill main body bottom external diameter, the drilling upper end periphery with
The drill main body bottom periphery forms chamfering inclined-plane.
Preferred scheme, the drill main body is integral type structure with the chamfering device.
The beneficial effects of the utility model are：（1）The utility model drill bit and chamfering device be integral type structure, it is to avoid is beaten
Situation loosely is connected during hole between drill bit and chamfering device；（2）Phenomenon of the glass orifice that the drill bit is got without chip；（3）
Using the drill bit to glass punching after, glass is also easy to from the mesopore of drill bit out, improve operating efficiency.

Specific embodiment
To make have a better understanding and awareness to architectural feature of the present utility model and the effect reached, to compared with
Good embodiment and accompanying drawing coordinate detailed description, are described as follows：
A kind of glass perforating drill with chamfering, including drill main body 1, the lower section of the drill main body 1 are provided with chamfering device
2, the lower end of the chamfering device 2 is provided with drilling 21, and 21 external diameters of the drilling are less than the bottom external diameter of the drill main body 1, the drilling
21 upper ends are peripheral to form chamfering inclined-plane 22 with the bottom of the drill main body 1 periphery, and most of chamfering inclined-plane is 45 °, as needed
30 ° or 60 ° can also be made, below the utility model architectural feature can be illustrated according to 45 ° of chamfering inclined-planes.The drill bit
Main body 1 and the chamfering device 2 be integral type structure, it is to avoid connects situation loosely during punching between drill bit and chamfering device.
Specific embodiment one
The band chamfering glass perforating drill that chamfering inclined-plane is 45 ° is provided in the present embodiment, falling with the angle is made
Angular bit head needs former, bushing, plug, steel pole, the former to be provided with several through holes；Bushing A is slightly wider than at the bushing E
Place, E is in parallel and spacing at A, and, for a adds b, in the embodiment, spacing a is 4mm, and spacing b is 18mm, two ends and spacing a at E
There is inclined-plane at vertical place, and bevel angle α is 45 °；The plug is inverted T shape, and upper end is slightly wider than at the B of lower end, and spacing c is 30mm,
Spacing d is 13mm.Specifically, first being put into down at the above-mentioned bushing E for processing in advance in former at C, make at bushing A with
Bottom is overlapped at former C, then above-mentioned plug is put into above-mentioned bushing, is made than being higher by 8 to 10mm at the A of bushing at the B of plug,
Then load work powder with the gap of above-mentioned plug in above-mentioned bushing, will be finally put at above-mentioned steel pole D and install work powder
At former C, then it is sintered cooling and can obtain the glass perforating drill with chamfering that chamfering inclined-plane is 45 °, this punching
Through oversintering, drill bit and chamfering device are integral type structure to drill bit, it is to avoid connect insecure between drill bit and chamfering device during punching
The phenomenon for causing both separate.
The beneficial effects of the utility model are：（1）The utility model drill bit and chamfering device be integral type structure, it is to avoid is beaten
Situation loosely is connected during hole between drill bit and chamfering device；（2）Phenomenon of the glass orifice that the drill bit is got without chip；（3）
Using the drill bit to glass punching after, glass is also easy to from the mesopore of drill bit out, improve operating efficiency.
It should be understood by those skilled in the art that, the utility model is not restricted to the described embodiments, above-described embodiment and
Simply principle of the present utility model, this practicality on the premise of the utility model spirit and scope are not departed from described in specification
New also to have various changes and modifications, these changes and improvements are both fallen within the range of claimed the utility model.This
The protection domain of utility model requirement is defined by appending claims and its equivalent.
