Description
Technical field
This utility model relates to cutter field, is related specifically to a kind of molding cutter head.
Background technology
Rose reamer has another name called counterbit.Counterbit can carry out plane, cylinder, the conical surface and the processing of other profiles to the end face in hole.?
On the hole processed when the cylindrical counter sink of processing, taper counter sink and end face boss, all can use counterbit.Table for mobile phone
For the lateral edges processing of face, owing to its lateral edges has upper and lower surface to need processing, and need the demand of symmetry, existing work
Skill is then required to distinguish top and bottom treat, and is divided into two different operations to carry out effective chamfering molding respectively, thus
Causing operation to increase, time cost cannot effectively reduce, and the synchronicity of top and bottom processing simultaneously is substantially reduced.
Utility model content
The technical problems to be solved in the utility model be to provide a kind of can simultaneously to mobile phone upper and lower surface side along molding
Forming cutter.
It is achieved through the following technical solutions above-mentioned purpose:
A kind of molding cutter structure, is provided with forming cutter in the bottom of handle of a knife, and described forming cutter is provided with four sections of sides and becomes
Type block, described forming cutter is positioned on the central shaft of handle of a knife, is separated mutually by a groove respectively, every section between every section of edge forming block
Described edge forming block is provided with two molding facets, and each molding facet is arc, wherein the first molding facet,
It is connected by a section between two molding facets and described groove, the second molding facet and the first molding facet
Junction is the angle of an outwardly convex, and the arc length of molding facet is cut towards the first molding from the second molding cutting
Direction, face is gradually reduced.
Further describing as to above-mentioned a kind of molding cutter structure, the bottom of described second molding facet is less than the
The bottom of one molding facet, the top of described second molding facet is higher than the top of the first molding facet；And the first one-tenth
The width of type facet is less than the width of the second molding facet.
Further describe as to above-mentioned a kind of molding cutter structure, on the same vertical height of forming cutter, first
Distance between surface and the central shaft of handle of a knife of molding facet is less than the surface of the second molding facet and the center of handle of a knife
Distance between axle.
Further describe as to above-mentioned a kind of molding cutter structure, described groove and the top of each molding facet
The straight line that portion, bottom are linked to be becomes 5 degree of angles with the central shaft of handle of a knife, in 90 degree of angles between described groove two section.
Further describing as to above-mentioned a kind of molding cutter structure, the top of four sections of edge forming blocks is a level
Face, the edge at two of which edge forming block top is provided with the binding site of the step raised up, described step and horizontal plane
It it is a vertical side.
The beneficial effects of the utility model are: be provided with 4 sections of edge forming blocks, can be effectively increased repetition excision forming mobile phone
Marginal texture, make molding precision more increase；Simultaneously for mobile phone top and bottom structure, it is in the same side plane relatively
Two edges when need to carry out chamfering, it is possible to disposably complete, saved the repetition process time of half；Furthermore, this is same
Step chamfering is effectively improved the stationkeeping ability of synchronous cutting, solves in top and bottom separation chamfer process and needs to reorientate and school
The problem of quasi-working depth, and the molding facet of circular arc can be avoided repeating cutting for a long time and tool face causes trench hinder
Evil workpiece.
Accompanying drawing explanation
Fig. 1 is the side structure schematic diagram that this is novel；
Fig. 2 is the bottom surface structure schematic diagram that this is novel.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described:
The direction term being previously mentioned in following example, such as " upper and lower, left and right " they are only the directions with reference to accompanying drawing, because of
This, the direction term of use is used to illustrate not for limiting this utility model.
As shown in Figure 1-2, a kind of molding cutter structure, it is provided with forming cutter in the bottom of handle of a knife, described forming cutter sets
Having four sections of edge forming blocks 1, described forming cutter is positioned on the central shaft of handle of a knife 2, respectively by one between every section of edge forming block 1
Groove 3 phase separates, and every section of described edge forming block 1 is provided with two molding facets, and each molding facet is arc, wherein
It is connected by a section 31 between first molding facet the 11, second molding facet 12 and described groove 3, the second molding
Facet 12 and the angle that junction is an outwardly convex of the first molding facet 11, and the arc length of molding facet is certainly
Second molding facet 12 is gradually reduced to the first molding facet 11 direction.The 4 sections of edge forming blocks being provided with, can effectively increase
Add the marginal texture of repetition excision forming mobile phone, make molding precision more increase.
Further describing as to above-mentioned a kind of molding cutter structure, the bottom of described second molding facet 12 is less than
The bottom of the first molding facet 11, the top of described second molding facet 12 is higher than the top of the first molding facet 11；
And first the width of molding facet 11 less than the width of the second molding facet 12.This is arranged can be at cutter rotation process
In, gradually workpiece lateral surface is increased lifting surface area, so that excision forming is more smooth and easy, prevent area transient change excessive, and
The problem causing burr or resistance to be instantly increased occurs.
Further describe as to above-mentioned a kind of molding cutter structure, on the same vertical height of forming cutter, first
Distance between surface and the central shaft of handle of a knife of molding facet 11 is less than surface and the handle of a knife 2 of the second molding facet 12
Distance between central shaft.
Further describe as to above-mentioned a kind of molding cutter structure, described groove 3 and the top of each molding facet
The straight line that portion, bottom are linked to be becomes 5 degree of angles with the central shaft of handle of a knife, in 90 degree of angles between 3 liang of sections of described groove.To cut
Face camber line is set at an angle with vertical plane, when rose reamer rotates with mobile phone upper and lower surface edge at an angle, has
Effect reduces the generation of burr.
Further describing as to above-mentioned a kind of molding cutter structure, the top of four sections of edge forming blocks 1 is a water
Plane, the edge at two of which edge forming block 1 top is provided with the combination of the step 4 raised up, described step and horizontal plane
Position is a vertical side 5.
This most novel technical scope is not imposed any restrictions by the above, all according to this utility model technical spirit to
