Description
Technical field
The present invention relates to steel wire wire drawing field, particularly a kind of diamond wire busbar wire-drawing die.
Background technology
Diamond wire is generally used for the cutting of silicon materials in photovoltaic industry, cutting of diamond material etc. in semicon industry.Gold
Firm line is using diamond wire busbar as matrix, on busbar made of coated abrasives.Diamond wire busbar is formed mostly by drawn steel wire,
Steel wire largely uses wire-drawing die in drawing process, and steel wire can generate in drawing process since material is deformed and rubbed
Heat, when especially lubricant effect is bad, friction coefficient increase, the heat generated by friction greatly increases, and seriously affects mold
Service life, to keep mold cooling, the general outer surface that mold is directly cooled down using water, but because die surface product compared with
Small, the heat taken away is few, so die wear is very fast.And the internal diameter in mold core just needs replacing mold more than certain size,
Therefore production cost is increased.
Invention content
The present invention provides a kind of diamond wire busbar wire-drawing dies, improve the lubricating ability and cooling effect of mold.
In order to achieve the above object, the present invention is achieved by the following technical programs：
A kind of diamond wire busbar wire-drawing die, including die ontology, the die ontology is equipped with a section in the axial direction
For circular through-hole, the through-hole includes inlet region, lubrication area, compressional zone, sizing area and outlet area successively from top to bottom, in institute
It states die wall upper edge in compressional zone and radially opens up at least one first cooling and lubricating groove, the die wall upper edge radial direction in the sizing area
At least one second cooling and lubricating groove is opened up, the die wall in the bottom side of the first cooling and lubricating groove and the second cooling and lubricating groove
On offer first through hole, the first through hole is used for the injection of lubricant.
Further, there are two the first cooling and lubricating groove tools, there are two the second cooling and lubricating groove tools.
Further, it is also equal on die wall in the bottom side of each first cooling and lubricating groove and the second cooling and lubricating groove
The second through-hole is offered, the first through hole and the second lead to the hole site are opposite, and second through-hole is used for the outflow of lubricant, institute
The second through-hole internal diameter is stated less than first through hole internal diameter.
Compared with prior art, the advantage of the invention is that：The compressional zone and sizing area of this diamond wire busbar wire-drawing die
Cooling and lubricating slot is all offered, utilizes first through hole that lubricant high pressure is injected cooling and lubricating slot in the course of work, draws steel wire
Better lubricant effect is kept during pulling out, substantially reduces frictional force and frictional heat；Lubricant also rises in drawing process
The effect of cooling is arrived, lubricant is taken out of heat by the second through-hole, passes through first through hole weight again after mold exterior cooling
New injection cooling and lubricating slot cools down mold.By the effect of these two aspects, make wire-drawing die using effect and
Service life greatly improves.
Description of the drawings
In order to illustrate the technical solutions in the embodiments of the present application or in the prior art more clearly, to embodiment or it will show below
There is attached drawing needed in technology description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments described in application, for those of ordinary skill in the art, without creative efforts,
It can also be obtained according to these attached drawings other attached drawings.
Fig. 1 is one embodiment of the invention diamond wire busbar wire-drawing die internal structure schematic diagram.
Fig. 2 is compressional zone and sizing area partial enlargement structural representation in Fig. 1
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, detailed retouch is carried out to the technical solution in the embodiment of the present invention
It states, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.Based on the present invention
In embodiment, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, shall fall within the protection scope of the present invention.
Refer to the attached drawing 1 and attached drawing 2, a kind of diamond wire busbar wire-drawing die, are integrally formed, described including die ontology
It is circular through-hole that die ontology is equipped with a section in the axial direction, and the through-hole includes entrance 1, lubrication area successively from top to bottom
2nd, compressional zone 3, sizing area 4 and outlet area 5, die wall upper edge radially opens up at least one first cooling and lubricating in the compressional zone
Groove 6, die wall upper edge radially opens up at least one second cooling and lubricating groove 7 in the sizing area, in the first cooling and lubricating
First through hole 8 is offered in the bottom side of groove and the second cooling and lubricating groove on die wall, the first through hole 8 is used for lubricant
Injection.
In the technical scheme, lubricant is injected in cooling and lubricating slot by first through hole, during steel wire drawing
Lubricant effect can be increased, reducing frictional force reduces frictional heat.
Preferably, there are two the tools of the first cooling and lubricating groove 6, there are two the tools of the second cooling and lubricating groove 7.
In the technical scheme, there are two the first cooling and lubricating groove tools, there are two the second cooling and lubricating groove tools.
Preferably, it is also offered on the die wall of each first cooling and lubricating groove 6 and the second cooling and lubricating groove 7
