Description
Technical field
The utility model is related to be machined precision hole machining reamer technical field, and in particular to a kind of reamer processing through-hole
Special chip breaking sword structure.
Background technology
Hole machined occupies an important position in Mechanical Processing Industry.According to statistics, for its labor content, hole machined
Workload accounts for about 30% or so of entire machining operations amount.No matter aperture knife tool is upper in design, manufacture or use, all
The characteristics of having itself.Reamer is a kind of precision cutting tool finished for centering, small diameter bore.It on pre-manufactured hole only
One layer of very thin metal is cut, if design is correct, manufacture is superior, and use is proper, can obtain higher dimensional accuracy and several
What form accuracy, finish are also higher.It is widely used in high-volume high accurate hole processing field, especially automotive field, aviation
Field, high-end Hydraulic Field are widely used.
Existing reamer is mostly straight trough design, this is because straight fluted reamer design is simple, production is easy, manufacturing cost is low, no
The 5 Shaft and NC Machining Test cutter and tool grinding machines for needing input expensive can also be manufactured and reach associated specifications.But straight fluted reamer
The disadvantage is that in the long bits class material of processing, such as：It is not easy chip breaking when steel part, stainless steel material.Processed hole is caused to be easy continuous
The chip of winding scratches, and even squeezes reamer cutting edge and collapses, leads to not stablize processing.
Therefore, in view of the above-mentioned problems, the utility model proposes a kind of new technical solutions.
Utility model content
The purpose of this utility model, which is to provide one kind, having chip breaking, chip removal effect, and chip breaking is good, and reamer processing quality is high, makes
The special chip breaking sword structure of through-hole is processed with the reamer of long lifespan.
The utility model is achieved through the following technical solutions：
A kind of reamer processing special chip breaking sword structure of through-hole, including reamer body and reamer mechanism, the reamer body one
End is equipped with circular arc type reamer mechanism, and the reamer mechanism is made of several reamer blades, the front end cutting of each reamer blade
Cutting edge position is provided with the rake face of negative rake, and the side of the rake face of negative rake is provided with chip breaking step, the negative rake
Rake face and chip breaking step match.
Further, the reamer blade is connected with reamer body by welding.
Further, the angle of the rake face of the negative rake is 10 ~ 15 degree.
Further, the rake face of the negative rake and chip breaking step match, and realize chip breaking and the effect to front clearance.
The utility model has the beneficial effects that：
1, straight fluted reamer can be made to have chip breaking effect, solve the long bits class material of processing, such as：Steel part, stainless steel material are not
The problem of chip breaking；
2, it can be manufactured using general tool grinding machine equipment, 5 expensive Shaft and NC Machining Test cutter and tool grinding machines need not be used to give birth to
Production, manufacturing cost is low, is simple to manufacture；
If the problem of 3, common straight fluted reamer encounters not chip breaking can directly be restructured, without redesigning production.
It can quickly solve the problems, such as that client uses the not chip breaking of reamer；
4, since chip breaking effect is good, reamer processing quality is high, service life is long.3-5 times of common straight fluted reamer can be improved
Service life.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the enlarged drawing in the portions A in Fig. 1.
Wherein：01, chip breaking step, 02, the rake face of negative rake, 03, reamer blade, 04, reamer body, 05, reamer machine
Structure.
Specific implementation mode
Explanatorily the utility model is described further below in conjunction with the accompanying drawings.
As shown in Figure 1 and 2, a kind of reamer processes the special chip breaking sword structure of through-hole, including reamer body 04 and reamer mechanism
05,04 one end of reamer body is equipped with circular arc type reamer mechanism 05, and reamer mechanism 05 is made of several reamer blades 03, each to cut with scissors
The nose-cut-ting edge oral area position of knife blade 03 is provided with the rake face 02 of negative rake, and the side of the rake face 02 of negative rake is provided with
Chip breaking step 01, the rake face 02 and chip breaking step 01 of negative rake match.
In the technical scheme, reamer blade 03 is connected with reamer body 04 by welding.
In the technical scheme, the angle of the rake face 02 of negative rake is 10 ~ 15 degree.
In the technical scheme, the rake face 02 and chip breaking step 01 of negative rake match, and realize chip breaking and to front clearance
Effect.
In the technical scheme, pass through rake face of the blade grinding with certain negative rake in straight fluted reamer（Generally
10-15 degree）, negative rake can generate forward cutting force, which chip can be discharged forward, prevent plowing from machined
Hole wall is ground out step on the rake face with certain negative rake, which can play the work for making chip crimp and fractureing
With the nose-cut-ting edge oral area position of reamer blade is provided with the rake face of negative rake, which can generate forward cutting
Power；Negative rake rake face side there are one chip breaking step, which can crimp chip and the chip that fractures；Negative
Under the rake face of anterior angle and the collective effect of chip breaking step, play the role of chip breaking and to front clearance.
It in the technical scheme, can be in straight fluted reamer by improving cutting edge geometric dimension form
Cutting edge portion grinding with certain negative rake step rake face, so that chip is produced when processing steel part class material
Raw clot phenomenon and to the cutting force being pushed forward to when chip on one side fracture while to being pushed forward, generate chip breaking and show to front clearance
As.Especially to processing through-hole steel part class material, chip breaking is with obvious effects.The blade type can also equally be used in blind hole occasion.
And the blade type can be manufactured using general tool grinding machine equipment, be produced without using high-end 5 Shaft and NC Machining Test cutter and tool grinding machine.It is raw
Produce at low cost, the market competitiveness is strong.
The embodiment of the utility model above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the utility model patent range therefore be interpreted as.It should be pointed out that for the ordinary skill of this field
For personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these belong to this
The protection domain of utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
