Abstract
The utility model is related to it is a kind of can quick chip removal alloy bit, it is characterised in that be provided with the fixed card slot equal with alloy cutter head cutting edge quantity in described drilling rod top ends, the cutting edge of described alloy cutter head is respectively placed in fixed card slot and is welded as a whole；The discharge groove parallel with drill rod axis is respectively equipped between multiple fixed card slots of described drill rod end, the discharge groove is connected with helical flute.The beneficial effects of the utility model are by setting discharge groove between the fixed card slot on drill rod end respectively and discharge groove is connected respectively with helical flute, so when alloy bit at work, rapidly discharged in the helical flute that scrap quickly can be entered on drilling rod by discharge groove, so as to effectively avoid the cutting edge of alloy cutter head repeat with scrap carry out friction cause the temperature of alloy cutter head to raise, the operating temperature of alloy bit is reduced, increases the service life and improves working efficiency.
Description
Technical field
A kind of hardware ＆ tools is the utility model is related to, more particularly to a kind of alloy bit for being easy to chip removal is main
To be applied to the fields such as hardware drill bit.
Background technology
Existing alloy bit is mainly made up of drilling rod and alloy cutter head, in order to improve the cutting ability of drill bit and using the longevity
Life, alloy cutter head needs to be welded on the end of drilling rod, so when drill bit at work, alloy cutter head can be quickly on working face
Carry out cutting operation.Its alloy cutter head of existing drill bit is welded on the end of drilling rod, and for the weldering of just alloy cutter head
Connect, set up separately in the end of drilling rod and put fixed card slot, the cutting edge of such alloy cutter head can be individually positioned in fixed card slot and weld
Connect and be connected to one.Because existing drill rod end external diameter is identical with the external diameter of helical flute, so when drill bit is in work
When making, scrap is not easy to discharge in time, causes the temperature rise of the alloy cutter head of drill bit, shortens service life and the reduction of drill bit
Working efficiency.
Utility model content
In order to solve existing alloy bit, scrap is not easy to discharge in time at work, influences the working efficiency of alloy bit
With the technical problem such as service life for shortening alloy bit, the utility model provide it is a kind of can quick chip removal alloy bit, this
Drill bit not only can quick chip removal, improve the working efficiency of alloy bit；Meanwhile it can also effectively reduce the work temperature of alloy cutter head
Degree, so as to extend the service life of alloy bit.
For solve above technical problem, the utility model adopt the technical scheme that it is a kind of can quickly chip removal alloy brill
Head, include drilling rod and alloy cutter head, helical flute is provided with described drilling rod, described alloy cutter head is arranged on drilling rod
End and alloy cutter head there are more than two cutting edges；It is provided with and alloy cutter head cutting edge number in described drilling rod top ends
Equal fixed card slot is measured, the cutting edge of described alloy cutter head is respectively placed in fixed card slot and is welded as a whole；Described
The discharge groove parallel with drill rod axis is respectively equipped between multiple fixed card slots of drill rod end, the discharge groove and helical flute
It is connected.
Further, described discharge slot cross-section is in circular arc, and radius R is 1.5mm~20mm.
Further, described alloy cutter head is provided with three cutting edges, and three are correspondingly provided with admittedly in described drill rod end
Determine neck.
Further, described alloy cutter head is provided with four cutting edges, and four are correspondingly provided with admittedly in described drill rod end
Determine neck.
The beneficial effects of the utility model are by setting discharge groove respectively simultaneously between the fixed card slot on drill rod end
Discharge groove is connected respectively with helical flute, so when alloy bit at work, scrap can quickly pass through discharge groove
Rapidly discharged in into the helical flute on drilling rod, so as to effectively avoid the cutting edge of alloy cutter head repeat and scrap
Carrying out friction causes the temperature of alloy cutter head to raise, and reduces the operating temperature of alloy bit, increases the service life and improves work
Benefit.
Brief description of the drawings
Fig. 1 be the utility model embodiment it is a kind of can the quick alloy cutter head of chip removal stereogram
Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
As shown in figure 1, the utility model for it is a kind of can quick chip removal alloy bit, include drilling rod 1 and alloy cutter head
2, helical flute 3 is provided with described drilling rod 1, described alloy cutter head 2 is arranged on the end of drilling rod 1 and alloy cutter head 2
With more than two cutting edges 21；The fixation equal with the cutting edge quantity of alloy cutter head 2 is provided with the described top ends of drilling rod 1
Neck 11, the cutting edge 21 of described alloy cutter head 2 are respectively placed in fixed card slot 11 and are welded as a whole；Described drilling rod 1
The discharge groove 4 with the diameter parallel of drilling rod 1 is respectively equipped between multiple fixed card slots 11 of end, the discharge groove 4 and debris
Groove 3 is connected；By discharge groove 4 is set respectively between the fixed card slot 11 on the end of drilling rod 1 and make discharge groove 4 respectively with spiral shell
Rotation chip area 3 be connected, so when alloy bit at work, scrap can quickly pass through discharge groove 4 enter drilling rod 1 on spiral shell
Rapidly discharged in rotation chip area 3, so as to effectively avoid what the cutting edge of alloy cutter head repeated from carrying out friction with scrap and cause
The temperature rise of alloy cutter head, reduces the operating temperature of alloy bit, increases the service life and improves working efficiency.
In the present embodiment, chip removal performance, described discharge groove 4 are influenceed in order to prevent scrap to be caught between fixed card slot 11
Section is in circular arc, and radius R is 1.5mm~20mm；The radius of discharge groove 4 can be adjusted accordingly according to the specification of alloy bit
Whole, the specification of alloy bit is bigger, and the radius of discharge groove 4 is just relatively bigger, thus more conducively quick chip removal；Specific numerical value
It is not further qualified；And the section of discharge groove 4 is set into circular arc, thus it can effectively prevent bulky grain scrap to be stuck in fixation
Between neck 11, chip removal effect is influenceed；The section of discharge groove 4 can also be set to V-arrangement or U-shaped certainly, but use circular arc scrap
Discharge is more smooth, and therefore, the embodiment of the present embodiment is preferred embodiment.
In the present embodiment, described alloy cutter head 2 is provided with three cutting edges 21, corresponding in the described end of drilling rod 1
Provided with three fixed card slots 11；Three cutting edges 21 are set to form triangle alloy cutter head, this alloy cutter head phase on alloy cutter head
To ratio in-line two cutting edges alloy bit working efficiency it is higher.
In the present embodiment, described alloy cutter head 2 is provided with four cutting edges 21, corresponding in the described end of drilling rod 1
Provided with four fixed card slots 11.Four cutting edges 21 are set to form cross alloy cutter head or X-shaped alloy knife on alloy cutter head 2
Head, this alloy cutter head it is relative again than in-line two cutting edges and triangle alloy cutter head alloy bit working efficiency
It is higher.
Above-described embodiment is not construed as to limitation of the present utility model, but any is made based on spirit of the present utility model
Improve, all should be within the scope of protection of the utility model.
