Abstract
The utility model discloses the shaping hobboing cutter of a kind of high strength cemented carbide fin, it is characterized in that, comprise the body and teeth portion that are integrally formed, axis hole is provided with in the middle part of described body, be provided with pin-and-hole in axis hole ring week, the shaping hobboing cutter of described fin is made up of the yG15-YG30 type converted steel adopting for mould class in K and the M class of IC.The utility model creatively overcomes traditional concept constraint, utilize high strength cemented carbide material to prepare the hobboing cutter run up, compare with high-speed tool steel cutter with the cutter that Hardmetal materials makes: several times to tens times ground can be become to improve cutter life; The result of use of rare metal can be improved, a large amount of saving steel, significantly reduce cutter cost of use; Greatly improve metal cutting speed, significantly improve productivity ratio, one time sharpening hobboing cutter can reach 15--25 hundred million peak fin rolling belt service life.
Description
Technical field
The utility model relates to fin hobboing cutter technical field, particularly relates to the shaping hobboing cutter of a kind of high strength cemented carbide fin.
Background technology
Fin rolling belt machine is used to manufacture radiator aluminum fin, such as: the hot fin of aluminum radiator, and middle cold air turbulent flow sheet, the special equipment of condenser fin and evaporator fin.And former is the critical component assembly of entire machine.Former is by the engagement of a pair forming hob precision, and band material (general thickness scope: 0.08-0.2mm) rolls the shutter that can obtain some groups of different directions of windowing after punching hobs by hobboing cutter; Simultaneously peak height bending on request, obtains original shaping fin.Existing state inner fin rolls matter cutter and all adopts high-speed tool steel, and carbon tool steel or alloy tool steel material are made, and its service life is short, generally only has several ten million to 2-3 hundred million peak; The fin amount processed with it and outward appearance poor, production efficiency is low and relative cost is high.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provides a kind of high strength cemented carbide fin shaping hobboing cutter.
The technical scheme adopted for realizing the purpose of this utility model is:
The shaping hobboing cutter of a kind of high strength cemented carbide fin, comprise the body and teeth portion that are integrally formed, be provided with axis hole in the middle part of described body, be provided with pin-and-hole in axis hole ring week, the shaping hobboing cutter of described fin is made up of the yG15-YG30 type converted steel adopting for mould class in K and the M class of IC.
Described teeth portion is provided with cutting edge, and described cutting edge and end face form the angle of 3 °.
Arc transition is adopted to concentrate to avoid the stress of both sides between the cutting edge of described teeth portion and trailing flank.
Compared with prior art, the beneficial effects of the utility model are:
The utility model creatively overcomes traditional concept constraint, utilize high strength cemented carbide material to prepare the hobboing cutter run up, compare with high-speed tool steel cutter with the cutter that Hardmetal materials makes: several times to tens times ground can be become to improve cutter life; The result of use of rare metal can be improved, a large amount of saving steel, significantly reduce cutter cost of use; Greatly improve metal cutting speed, significantly improve productivity ratio; Improve dimensional accuracy and the surface roughness of product to be processed, adapt to the requirement of automatic production line.And carbide hob bending strength is good, hardness is high, and wearability is good, and the vertical sword retention time is long, and cost performance is high, long service life.One time sharpening hobboing cutter can reach 15--25 hundred million peak fin rolling belt service life.
Accompanying drawing explanation
Fig. 1 is that the shaping hobboing cutter of fin coordinates schematic diagram;
Figure 2 shows that the structural representation of the shaping hobboing cutter of high strength cemented carbide fin of the present utility model;
Figure 3 shows that the structural representation of blade.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As Figure 1-3, the shaping hobboing cutter of high strength cemented carbide fin of the present utility model comprises the body and teeth portion 3 that are integrally formed, axis hole 1 is provided with in the middle part of described body, be provided with pin-and-hole 2 in the ring week of axis hole, the shaping hobboing cutter of described fin is made up of the Hardmetal materials of K and the M class adopting IC.Specifically, the yG15-YG30 type converted steel being used for mould class is adopted to make.
In prior art, all adopt yG6, yG8, yT14 and yT15 etc. as high speed cutter, the carbide alloy of model, its bending strength is at 150kg/mm
2even, its hardness is about 90, and the utility model adopts in routine the material being used as mould breakthroughly, and as being used as the material of cold upsetting die of car, cold extrusion mould etc., as yG15, yG20 or yG25, its bending strength is large, generally at 200kg/mm
2above, even 300kg/mm can be reached
2, and simultaneously hardness also more than 85, that is, sacrificial section hardness and greatly improve its intensity.
High strength cemented carbide hobboing cutter elastic modelling quantity is little, good rigidly, keeps self intrinsic shape ability strong; Carbide hob linear expansion coefficient is little, this guarantees the rolling cut that closely cooperates of hobboing cutter often pair of blade at work, and carbide hob bending strength is than the low about half of high-speed tool steel, like this when the upper and lower cutter shaft depth of parallelism is poor, footpath is jumped and end jumping exceeds standard, and also can be formed by self and ensure certain service life when axial float is large and running accuracy is poor.
Further, for window impact flexibility in an instant washed open by hobboing cutter, optimize the performance of carbide hob, cutting edge 10 and the end face of described teeth portion form the angle of 3 °, namely, cutting edge and back form the angle of 87 °, change the design that original cutting edge is vertical with back, and arc transition also can be adopted between the cutting edge of the teeth portion simultaneously and trailing flank to concentrate to avoid the stress of both sides.
Compare with high-speed tool steel cutter with the cutter that high strength cemented carbide material makes: several times to tens times ground can be become to improve cutter life; The result of use of rare metal can be improved, a large amount of saving steel, significantly reduce cutter cost of use; Greatly improve metal cutting speed, significantly improve productivity ratio; Improve dimensional accuracy and the surface roughness of product to be processed, adapt to the requirement of automatic production line.Carbide hob bending strength is good, and hardness is high, and wearability is good, and the vertical sword retention time is long, and cost performance is high, long service life, and one time sharpening hobboing cutter can reach 15--25 hundred million peak fin rolling belt service life.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
