Description
Technical field
The present invention relates to Milling Process technical fields, specifically, more particularly to a kind of mold copper electrode processing single-blade
Left-hand circular polarization and its application method.
Background technique
Mold is manufacturing important foundation technological equipment, and the mass production of industrial products and the exploitation of new product are all
It is be unable to do without mold, has 60% -90% part to need to use die forming in the common industrial products of people.
With social development, many die products, especially personal electric product, the requirement to appearance and minutia are got over
Come it is higher so that processing related die copper electrode need to retain a large amount of sharp edge feature.Since copper electrode material has
Good moulding, when Milling Process sharp edge, easily generation cutting burr.When electrode part size is small, seamed edge and surface matter
When amount requires high, these cutting burrs are difficult to remove by additional process without lesion electrode surface.With personal consumption electronics
The demand of the development of product, accurate copper electrode is increasing, therefore, few impulse- free robustness processing technology tool of research copper electrode part
It is of practical significance.
Left-handed cutter is since the side cut sword of cutter is left hand helix, and leading to the end face sword of cutter, there are before biggish bear
Angle, therefore left-handed cutter is generally unsuitable for the operating condition of common milling, i.e. the flank edge of cutter and end face sword simultaneously participates in cutting.
However, left-hand circular polarization can generate a downward pressure in Flank machining, the top of Flank machining theoretically can reduce
Burr.Therefore, left-hand circular polarization side milling deburring field with good application prospect, but on condition that cutter end face sword can be overcome
The influence of negative rake.
Current commercialized left-handed cutter is mainly used for cutting acrylic board, using the pushing component of left-hand cut sword, protects
It is complete to demonstrate,prove slab edge, reduces cutting burr.However in the application scheme, cutter for same, which only has flank edge, does not have end face sword,
Point of a knife is sharp cusp, does not do intensive treatment, and flank of tool sword is used only in when processing, and point of a knife position is not contacted with workpiece.Cause
Not can be used directly in metal parts Flank machining for this such cutter structure, is easy to cause point of a knife fragmentation or point of a knife quickly to grind
Damage.
Have the industrial application of left-handed cutter: having left-handed cutter is usually all cylinder profile shape, is used for acryl plates
Blanking.Its point of a knife is not involved in cutting, no shear blade (the left-handed cutter of single-blade).
Patent 201120231256.6 reports " a kind of numerical control end milling cutter for burr-free processing composite material ", patent
201720223087 report " a kind of impulse- free robustness side milling cutter processing ".Both cutters are all that left-right rotary cutting edge intersects row
Column, left-right rotary cutting edge be all processed with flank edge based on, there are overlap joint sections in two kinds of blades.Due in cutter grinding process not
There are cutting edge bias avoidablely, and causing processing rear knife edge overlapping part in workpiece surface, there are traces, to reduce workpiece
Surface quality, therefore both cutter cutters are not all suitable for the copper electrode part processing to accessory appearance requirement harshness.
Therefore, for precision copper electrode machining, some deburring methods, are had the drawback that in the prior art
1) patent 201710566021.3, a kind of method of red copper electrode deburring, existing defects include: that may be only available for
Top surface is the electrode machining of plane, is not suitable for inclined-plane or curved surface electrode processing.
2) patent 201120231256.6, a kind of numerical control end milling cutter for burr-free processing composite material, existing defects include: a left side
Right-hand cut sword is staggered, and there are linking overlap-add regions.Since cutter deflection is inevitable, will lead to workpiece surface, there are knives
Trace is not suitable for the copper electrode processing high for surface quality requirements.In addition, the cutter is only applicable to side milling, it is not suitable for tiltedly flat
Face or curved surface electrode processing.
3) 201720225087.1 a kind of impulse- free robustness side milling cutter processing, existing defects include: that left-right rotary cutting edge interlocks
Arrangement, there are linking overlap-add regions.Since cutter deflection is inevitable, will lead to workpiece surface there are tool marks, be not suitable for for
The high copper electrode processing of surface quality requirements.In addition, the cutter is only applicable to side milling, it is not suitable for tapered plane or curved surface electrode adds
Work.
4) the left-handed cutter of the single-blade of acrylic board blanking, existing defects include: that point of a knife is sharp, do not do rounded corner or fall
The intensive treatment at oblique angle, when the Flank machining for being applied to have point of a knife to participate in cutting, point of a knife position is easy fragmentation or rapidly abrasion,
Cutter life is short.In addition, sharp point of a knife can not be applied to tapered plane or curved surface electrode is processed.
In actual mould precision copper electrode machining, reduce burr ruler often through repeated multiple times method for finishing manufactured
It is very little, cause process time to extend, processing cost increases.
Summary of the invention
According in actual mould precision copper electrode machining set forth above, subtract often through repeated multiple times method for finishing manufactured
The technical issues of small burr size, causes process time to extend, and processing cost increases, and a kind of processing of mold copper electrode is provided
Single-blade left-hand circular polarization and its application method.The present invention mainly utilizes milling cutter to have a left-handed blade, and point of a knife has rounded corner or falls
Oblique angle, by improvement of cutter structure and processing technology, under the premise of guaranteeing that copper electrode seamed edge and surface are not damaged, only with one
Secondary finish-milling can make copper electrode seamed edge lack impulse- free robustness, shorten process time to play, and reduce finishing cost.
The technological means that the present invention uses is as follows:
A kind of single-blade left-hand circular polarization of mold copper electrode processing, including hard alloy cylindrical milling cutter main body, the hard close
