Description
Technical field
The present invention relates to a kind of rose cutters, and in particular to a kind of surface joining mold milling rose cutter.
Background technology
The finishing for splicing mold to automobile panel at present uses monoblock type rose cutter or blade type straight line sword bulb
Milling cutter, monoblock type rose cutter cost is higher, blade type straight line sword rose cutter due to cutting edge be straight line, cause cutting force and
It vibrates larger, and then influences machining accuracy, surface quality and cutter life；Conventional knives chip rose cutter blade and knife
It is easily loosened after bar connection；The milling of surface joining mold can aggravate the impact suffered by cutting edge roundness, and blade is caused not up to grind
Excessive wear or breakage occur before blunt standard, and then influences milling system stability and processing quality；Traditional milling cutter point of a knife
It cannot participate in cutting, when tool axis is vertical with workpiece surface, it may occur that zero cuts phenomenon, and zero cuts so that cutter occurs with workpiece
It mutually squeezes, so not only so that workpiece surface quality is poor, while corner wear is also very violent, accelerates the failure of cutter, most
Processing cost is improved eventually, reduces workpiece surface quality.
To sum up, existing blade type rose cutter workpiece surface quality is poor, high processing costs.

It is sinusoidal line cutting edge, the side of the first cutting edge 1 is connected with major first face 2, and major first face 2 is less than on rose cutter
Surface 7 is arranged and the two is arranged in parallel, and major first face 2 is connect with rose cutter upper surface 7 by 3 transition of first groove face,
The other side of first cutting edge 1 is connected with major first flank 9；The side of second cutting edge 4 is connected with the second rake face 17, and second
Rake face 17 is arranged less than rose cutter lower surface 11 and the two is arranged in parallel, the second rake face 17 and rose cutter lower surface 11
It is connected by 12 transition of second groove face, the other side of the second cutting edge 4 is connected with the second flank 5, the first cutting edge 1 and the
Two cutting edges, 4 junction is provided with point of a knife B, and major first face 2 and the second rake face 17 are not in the same plane.
Further, first groove face 3 and second groove face 12 are concave curved surface.
Further, 1 cutting edge A of the first cutting edge is the composite construction of chamfered edge 16 and blunt circle 15.
Further, blunt circle 15 is variable curvature circular arc, and 15 curvature of blunt circle is become larger by rake face to flank.
Further, the micro- sword structure of S-shaped for participating in cutting is provided at point of a knife B.
Further, the micro- sword structure of S-shaped is made of first micro- sword 14 and second micro- sword 13, the cutting of first micro- sword 14 and first
Sword 1 is connected, and second micro- sword 13 is connected with the second cutting edge 4.
Further, the center of rose cutter is machined with trip bolt hole 8, and rose cutter is connected by trip bolt and knife bar
It connects.
The present invention has the advantages that compared with prior art：
The surface joining mold milling of the present invention cuts tooth shape with rose cutter and uses sinusoidal sword, sinusoidal sword that can drop
Low Milling Force mitigates vibration cutting, and then improves the suface processing quality of surface joining mold；
The present invention increases the contact area of knife bar and blade since grooved surface is designed as curved surface so that blade is not
Loose phenomenon is easily generated in milling process, and then improves the machining accuracy of part；
The cutting edge cutting edge of the present invention is chamfered edge and blunt circle composite construction, and wherein blunt circle is variable curvature arc structure, the knot
Structure greatly improves cutting edge shock resistance, while reducing major first flank rate of depreciation, improves cutter life and workpiece
Suface processing quality；
The present invention point of a knife at have can participate in cutting the micro- sword structure of S-shaped, traditional rose cutter when tool axis with
When workpiece surface is vertical, it may occur that zero cuts phenomenon, not only reduces workpiece surface quality, but also can accelerate corner wear rate, this
The micro- sword of S-shaped of invention solves the above problem, still there is cutting edge progress at point of a knife when tool axis is vertical with workpiece surface
Cutting avoids the cutting of point of a knife squash type, not only increases workpiece surface quality, but also can overcome point of a knife sharp wear
Problem.
