The present invention provides a kind of reamers, the reamer includes ceramic tip and hard alloy substrate, the ceramic tip after ripe cermet turning molding with the carbide filler using being welded together, and to form above-mentioned reamer, and the reamer has been taken the processing of destressing technique.The processing technology of the reamer further includes the step of being embedded in thermal insulation material after the reamer is brazed, be slowly cooled to room temperature the reamer.The reamer handled using processing technology of the present invention can improve service life, reduction in the numbers of seconds.
Description
Technical field
The present invention relates to a kind of reaming tool, more particularly to a kind of processing technology of reamer.
Background technology
Hole machined tool applied to output bracket housing it is initially use be hard alloy boring cutter, but hard alloy boring cutter
Blade life it is low, pore size and roughness are all unstable.Frequent tool changing changes program, and production efficiency is low, and defect rate also occupies height
Under not.After using coated carbides reamer instead later, there are certain raising in quality stability and service life, but carbide-tipped reamer into
This height is unable to coating after reconditioning, influences service life, and at most can only reconditioning 2 times.
If both of these problems are solved using ceramet group instinct, but there is also some problems.According to bulk metal
Ceramics can have the disadvantage that：First, price, client are difficult to receive.2nd, domestic cermet material just starts to research and develop, and quality is not
Stablize.3rd, external cermet material limits outlet again.According to the side for adding cermet weld tabs on hard alloy substrate
Formula can solve cost problem, but due to being very easy to cracking, finished product after cermet material hardness height and steel matrix high-temperature soldering
Rate is extremely low.
Therefore it needs to be improved the processing technology of reamer above-mentioned.
Invention content
The reamer and its processing technology of reamer service life can be simultaneously improved the object of the present invention is to provide a kind of reasonable cost.
In order to solve the present invention at least part technical problem, a kind of reamer, the reamer include ceramic tip and
Hard alloy substrate, the ceramic tip are welded in after being molded using ripe cermet turning with the carbide filler
Together, to form above-mentioned reamer, and the reamer has been taken the processing of destressing technique.
Wherein, which includes head and shank, and the apical head is equipped with multiple ceramic tips, the reamer
Main oil-hole and branch oilhole are additionally provided with, the main oil-hole runs through the laterally head and the end face of the shank, the branch oilhole pass through
It wears the circumferential surface on the head and is connected with the main oil-hole.
Wherein, which is equipped with 6 straight trough swords, and minute of angle is 57 °, 60 ° and 63 °.
Wherein, the radial rake of the straight trough sword is 2 °.
Wherein, the hard alloy substrate uses Talide.
The present invention also provides a kind of processing technology for processing above-mentioned reamer, which includes quilt after reamer soldering
The step of being embedded to thermal insulation material, being slowly cooled to room temperature the reamer.
Wherein, which further includes remaining soldering flux when cleaning reamer surface soldered with boiling water and is down to room naturally
The step of temperature.
Wherein, which further includes the step of carrying out blasting treatment to the reamer.
Wherein, which further includes the step of carrying out low-temperature treatment to the reamer.
Reamer of the present invention can improve service life.
The reamer handled using processing technology of the present invention can improve service life, and reduction in the numbers of seconds improves whole efficiency.
It should be appreciated that the general description and the following detailed description more than present invention is all exemplary and illustrative,
And not restrictive.These detailed descriptions are it is intended that the present invention being somebody's turn to do such as claim provides further explanation.
Description of the drawings
It is to provide further understanding of the invention including attached drawing, they are included and form the part of the application,
Attached drawing shows the embodiment of the present invention, and plays the role of the explanation principle of the invention together with this specification.In attached drawing：
Fig. 1 shows the schematic diagram of reamer of the present invention.
Fig. 2 shows the schematic diagrames of reamer head of the present invention blade.
Specific embodiment
The embodiment of the present invention is described with detailed reference to attached drawing now.Now with detailed reference to the preferred implementation of the present invention
Example, its example is shown in the drawings.In the case of any possible, phase is represented by identical label is used in all the appended drawings
Same or similar part.In addition, although the term used in the present invention is selected from public term, this
Some terms mentioned in description of the invention may be that applicant carrys out selection by his or her judgement, and detailed meanings are at this
Illustrate in the relevant portion of the description of text.In addition, it is desirable that not only by used actual terms, and be also to by each
Meaning that term is contained understands the present invention.
Reamer of the present invention includes head 11 and shank 12, and the top on head 11 is equipped with multiple blades 13.
As an embodiment, which is equipped with 6 blades, is straight trough sword, and the minute of angle of continuous 3 blades 13 is
57 °, 60 ° and 63 °.The radial rake of the blade 13 is 2 °.
Reamer of the present invention uses hard alloy, and as basis material, blade is cut into using ripe cermet bit piece
Ceramic tip is fixed on hard alloy substrate by type using soldering processes.The reamer is equipped with cold hole 14 and Zhi Nei in main
Cold hole 15, cold hole 14 is run through in cold hole 15 in the laterally head 11 and the end face of the shank 12, the branch in the master
The circumferential surface on the head 11 is simultaneously connected with hole 14 cold in master, interior cold hole plug during to avoid welding, using first welding in perforating branches again
The mode in cold hole.
As an embodiment, the matrix of reamer of the present invention uses Talide.
But it since cermet material is different from the coefficient of thermal expansion of hard alloy, is very easy to out after high-temperature soldering
It splits, causes to scrap.The processing technology that reamer of the present invention uses employs multistage destressing, can effectively avoid what weld tabs cracked
Problem specifically includes：
1. after ceramic tip is soldered to hard alloy substrate, taking isothermal holding, the reamer is allowed to be slowly dropped to room temperature,
Avoid temperature change too fast cracking.
2. remaining soldering flux when cleaning reamer surface soldered with boiling water, and it is down to room temperature naturally.
3. pair reamer carries out blasting treatment, to go de-stress.
4. pair reamer carries out low-temperature treatment, to go de-stress.
By 5-10 times of above-mentioned processing technology treated working life of reamer of the present invention is original turning insert, and can be anti-
Multiple reconditioning 5 times or more, defect rate is reduced to 0.1%~0.2%, and whole efficiency also improves 2~3 times than originally.
Although the present invention is described with reference to current specific embodiment, those of ordinary skill in the art
It should be appreciated that above embodiment is intended merely to illustrate the present invention, can also be done in the case of without departing from spirit of the invention
Go out various equivalent change or replacement, therefore, as long as to the variation of above-described embodiment, change in the spirit of the present invention
Type will be all fallen in the range of following claims.
