Description
Technical field
The present invention relates to the cutting-tool engineering field of machining, and in particular to twolip compression type slotting cutter.
Background technology
With the development of science and technology various composites are more and more applied in industry, it is therefore desirable to meeting material
The machining that material is molded, at present to the multiplex conventional slotting cutter of processing of composite, conventional slotting cutter is in processing
Shi Rongyi produces vibration and causes the composite being cut burr occur, and composite receives cutting force effect meeting spreading point
Layer, easily causes tool damage and scraps the workpiece of processing, and the material of outer layer panel is especially compounded with cutting soft plastic
When, situations such as layering, burr often occurs, therefore a kind of slotting cutter for being exclusively used in cutting composite is badly in need of being employed.
The content of the invention
The technical problems to be solved by the invention are directed to drawbacks described above, there is provided twolip compression type slotting cutter, it is right to be exclusively used in
Composite carries out machining, be not in processing layering, burr situations such as, crudy is high.
The technical solution adopted for the present invention to solve the technical problems is as follows：
Twolip compression type slotting cutter, including handle of a knife and handle of a knife front end blade, the blade is provided with twice spiral cutting sword,
Spiral cutting sword be sectionally assembled cutting edge, formed by connecting before and after multi-segment structure identical helical structure, helical structure by
Twice are left-handed and dextrorotation spiral cutter hub is respectively screw half cycle spiral and forms with same axle center, and the spiral cutter hub back side is uniformly provided with
Multiple tracks is spiral helicine to carve the back of the body, and the seamed edge of spiral cutter hub and the seamed edge of the quarter back of the body are cutting edge, and all of seamed edge is cutting edge,
That is cut in cutting is more thorough, and the twolip compression type slotting cutter of height rotation will cut to be assigned on each cutting edge,
Make the cutting force being subject to balanced, be difficult to cause vibrations, it is to avoid be deformed or shake to cause because cutter hub cutting edge local pressure is excessive
It is cut material and produces layering, spiral helicine bit-withdrawing slot, the seamed edge side edge of all spiral cutter hubs is formed between two spiral cutter hubs
The spiral cutting sword of twolip compression type slotting cutter is constituted, spiral cutting sword is not connected to cutting edge, end to end spiral for interruption
The circumferential angle of structure its abutted surface is inconsistent, and the abutted surface of multiple end to end helical structures its circumferential even angle is set,
The spiral cutting sword for making milling cutter overall is evenly distributed, and in cutting, stress equalization is difficult to cause vibrations, reduces the generation of burr, place
Cross to form milling cutter end sword in the front edge of blade two spiral cutter hubs foremost, two spiral cutter hub front edges are in same
Plane, two spiral cutter hub front ends are constituted by cambered surface and inclined-plane, two spiral cutter hubs foremost on cutter hub axle center vis-a-vis
Cambered surface seamed edge be front edge, cambered surface is the rear knife face of front edge, and cambered surface and inclined-plane joint are chisel edge, and cambered surface is front edge
Knife face afterwards, cambered surface and inclined-plane joint are chisel edge, chisel edge can be cut with assisted machining end sword when milling cutter rotate after residual hair
Thorn, and most burr excision is clean at last, makes the surface quality of composite after the completion of final machining high.In same plane
Front edge make the surface quality of the bottom land in cutting slot good, impulse- free robustness.
Further, the bit-withdrawing slot of the previous helical structure in helical structure joint and latter helical structure are cut
Sword is cut with arc notch transition.Arc notch transition makes chip smoothly discharge, and will not be clashed into cutting edge while discharge and damaged
Bad cutting edge is splashed to composite just the reduction of surface quality is caused in face with cutting edge collision.
Further, the blade and handle of a knife joint are with chamfered transition, ramp structure direction and corresponding spiral cutter hub
The hand of spiral conversely, and ramp structure seamed edge be cutting edge, ramp structure produce air drag it is small, reduce milling cutter vibration
Produce, the cutting edge of ramp structure seamed edge plays a part of to reject burr when thicker composite is cut.
Further, the spiral intersection of the blade two spiral cutter hubs foremost caves inward, and is recessed and moves back
Bits groove is communicated, and chip is smoothly discharged when sword machining is held.
Preferably, the front end external diameter of the helical structure is more than rear end external diameter, helical structure front end maximum outside diameter and handle of a knife
External diameter is identical.
The beneficial effects of the invention are as follows：Using such scheme, the cutting edge of this twolip compression type slotting cutter is evenly distributed,
The cutting force equilibrium being subject to during cutting feed is difficult to collapse knife, and composite is subject to power also equilibrium will not produce layering, cutting edge
Impulse- free robustness after cutting layer by layer, surface quality is good, the smooth non-stick knife of chip removal, especially in the composite of cutting soft plastic, due to
Beveling sword is discontinuous, and correspondence chip area is also discontinuous, but the quarter back of the body texture at the spiral cutter hub back side contributes to the discharge of cutting, carves
The back of the body be evenly distributed promote cutting adhesion on milling cutter.
Brief description of the drawings
By detailed description below in conjunction with the accompanying drawings, the present invention is foregoing will to be become with other objects, features and advantages
Obviously.
Fig. 1 is structural representation of the invention.
Wherein：1 is handle of a knife, and 2 is blade, and 3 is helical structure, and 3.1 is spiral cutter hub, and 3.2 to carve the back of the body, and 3.3 is bit-withdrawing slot,
3.4 is front edge, and 3.5 is chisel edge.
Specific embodiment
Twolip compression type slotting cutter as shown in Figure 1, including handle of a knife 1 and the front end of handle of a knife 1 blade 2, blade 2 is provided with twice
