Abstract
The invention relates to the technical field of cutting tools, in particular to a novel hard alloy molding knife. The novel hard alloy molding knife comprises a knife handle and a cutting part arranged at the front end of the knife handle, wherein a long knife neck is arranged between the knife handle and the cutting part, the cutting part comprises a first cutting portion and a second cutting portion, the first cutting portion and the second cutting portion are in transition connection through a conical transition part with an arc-shaped conical surface, the longitudinal section of the second cutting portion is in the shape of a kidney, the first cutting portion is spherical, the end, with the larger diameter, of the transition part is connected with the second cutting portion, transition is achieved at the position where the second cutting portion is connected with the knife neck through a chamfered structure, multiple spiral cutting edges are evenly arranged on the whole circumferential surface of the cutting part, the spiral cutting edges intersect at the center of the front end of the first cutting portion and extend to the chamfered structure where transition is achieved between the second cutting portion and the knife neck, spiral chip receding grooves are formed in positions opposite to the spiral cutting edges, the cutting part is unique in structure, special-shaped grooves can be machined, and the quality of a machined surface is high.
Description
Technical field
The present invention relates to cutting tool technical field, be specifically related to a kind of novel hard alloy forming cutter.
Background technology
During present alloy product has been widely used and has produced and live, the wide variety that aluminium gold closes, be that the structure of the product that material is produced also becomes increasingly complex with alloy, more and more diversified, the requirement that the variation of corresponding alloy product structure makes it add tool setting in man-hour tool in forming and cutting is also more and more higher, especially to the alloy product with abnormal-shape ditch structure, existing cutter generally cannot be processed or in working angles, need to change multiple cutter and repeatedly process, not only waste many tool changing in man-hour tool trouble, and the surface quality after processing does not often reach instructions for use, surface quality is poor.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned defect, provides a kind of novel hard alloy forming cutter, and cutting portion structure is unique, and can process the groove of abnormal shape, machined surface quality is high.
The technical scheme that the present invention solves the employing of its technical problem is as follows:
A kind of novel hard alloy forming cutter, comprise handle of a knife, the cutting portion of handle of a knife front end, this forming cutter is with the machine-shaping of carbide alloy one, it is rimmer knife neck between described handle of a knife and cutting portion, cutting portion comprises the first cutting tip and the second cutting tip, connect with tapered transitional transition between first cutting tip with the second cutting tip, the longitudinal section of the second cutting tip is waist type, first cutting tip is ball-type, the conical surface of tapered transitional is the arc conical surface, one end that transition part diameter is large connects with the second cutting tip, the diameter of transition part and the first cutting tip joint is less than the first cutting tip, second cutting tip and cutter neck joint are with chamfering structure transition, the overall side face of described cutting portion is provided with multiple tracks spiral cutting sword uniformly, described spiral cutting sword crosses in the first center, cutting tip front end, spiral cutting sword extends to the chamfering structure place of the second cutting tip and the transition of cutter neck, spiral cutting sword opposite position is spiral bit-withdrawing slot, first cutting tip, second cutting tip can carry out machining to workpiece individually or simultaneously, cutting edge spreads all over whole cutting portion, spiral cutting sword extends to the chamfering structure of the second cutting tip and the transition of cutter neck from the first cutting tip front end always, so each structural plane of cutting portion all can be used for processing workpiece, and multiple tracks spiral cutting sword distribution fine uniform, the surface quality processed is high, adding man-hour, by adjusting the placed angle of workpiece, or adjustment forming cutter, the different structure place of forming cutter cutting portion is processed workpiece, to process special-shaped groove, the first spherical cutting tip can be used for cutting conventional groove, transition portion can cut the groove of cambered surface, in conjunction with the second cutting tip, the angle of adjustment cutter can process the groove of various abnormity.
Further, described transition part and the first cutting tip, the second cutting tip joint are and seamlessly transit.
Further, the radian direction of the described transition part arc conical surface is for pointing to inside axle center, and the transition part arc conical surface is inside, when chip, can not produce the first spherical cutting tip and interfere, and be combined with the first cutting tip and can process more abnormal-shape ditch.
Further, described first cutting tip maximum gauge is less than the second cutting tip maximum gauge.
The invention has the beneficial effects as follows: adopt such scheme, the cutting portion that first cutting tip, the second cutting tip and transition part are formed, its structure is unique, in conjunction with cutting way, direction etc., conveniently machining is carried out to multiple abnormal-shape ditch, and the side face of the uniform cutting portion of spiral cutting sword, make the surface quality of cutting high, utilize this forming cutter can carry out Precision Machining to the mold cavity etc. of various structures complexity.
Accompanying drawing explanation
By the detailed description below in conjunction with accompanying drawing, aforesaid and other object, the feature and advantage of the present invention will become apparent.
Fig. 1 is structural representation of the present invention.
Wherein: 1 is handle of a knife, 2 is cutter neck, and 3 is the second cutting tip, and 4 is the first cutting tip, and 5 is transition part, and 6 is spiral cutting sword.
Detailed description of the invention
As shown in Figure 1 with carbide alloy one machine-shaping a kind of novel hard alloy forming cutter, comprise handle of a knife 1, the cutting portion of handle of a knife 2 front end, it is rimmer knife neck 2 between handle of a knife 1 and cutting portion, rimmer knife neck 2 is convenient to the machining compared with deep trench, cutting portion comprises the first cutting tip 4 and the second cutting tip 2, connect with tapered transitional 5 transition between first cutting tip 4 with the second cutting tip 2, transition part 5 and the first cutting tip 4, second cutting tip 3 joint is and seamlessly transits, the longitudinal section of the second cutting tip 2 is waist type, first cutting tip 4 is ball-type, the maximum gauge of the first cutting tip 4 is less than the maximum gauge of the second cutting tip 3, the conical surface of tapered transitional 5 is the arc conical surface, the radian direction of the arc conical surface is for pointing to inside axle center, one end that transition part 5 diameter is large connects with the second cutting tip 3, the diameter of transition part 5 and the first cutting tip 4 joint is less than the first cutting tip 4, second cutting tip 3 and cutter neck 2 joint are with chamfering structure transition, the overall side face of cutting portion is provided with multiple tracks spiral cutting sword 6 uniformly, spiral cutting sword 6 crosses in the first center, cutting tip 3 front end, spiral cutting sword 6 extends to the chamfering structure place of the second cutting tip 3 and cutter neck 4 transition, spiral cutting sword 6 opposite position is spiral bit-withdrawing slot.
The above is only preferred embodiment of the present invention, not does any pro forma restriction to the present invention, every according in technical spirit of the present invention to any simple modification, equivalent variations that above embodiment is done, all fall within protection scope of the present invention.
