Abstract
The utility model discloses a PCBN (Polycrystalline Cubic Boron Nitride) blade applied to special-shaped screw processing, which belongs to the technical field of super-hard tools. One end of a machine card blade is connected with PCBN cutter particles by welding; the top of the PCBN cutter particles consists of a main cutting edge and pre-cutting edges; both sides of the main cutting edge are provided with a left feeding pre-cutting edge and a right feeding pre-cutting edge; and the main cutting edge is in circular-arc transition connection with the left feeding pre-cutting edge and the right feeding pre-cutting edge. The PCBN blade has the characteristics and advantages that: due to the high hardness, high wear resistant and high temperature resistance of PCBN, the PCBN blade has longer service life than a hard alloy tool; the PCBN cutter particles are connected with a high-toughness hard alloy substrate, so that the overall performance of a product is enhanced; two pre-cutting edges are arranged, so that impact to the main cutting edge, caused by non-uniform cutting allowance of raw materials, can be reduced effectively; and an international standard hard alloy machine card blade substrate has a wider application range and a quicker batch production delivery period.
Description
Technical field
The utility model relates to a kind of PCBN blade that is used for special-shaped screw thread processing, belongs to the sintered carbide tools technical field.
Background technology
Existing machining tool is main with hard alloy cutter, and PCBN (polycrystalline cubic boron nitride) cutter only has an external family producing, and the off size reason of design cutting; Grope development domestic belonging to.
Summary of the invention
The purpose of the utility model is to provide a kind of PCBN blade that is used for special-shaped screw thread processing.
The utility model provides a kind of PCBN blade that is used for special-shaped screw thread processing, improves working (machining) efficiency.Cut down finished cost, guarantee stabilized quality.
The utility model solves the technical scheme that the process technology problem is taked: a kind of PCBN blade that is used for special-shaped screw thread processing; In order to solve the big problem of the special-shaped difficulty of processing of PCBN material, the utility model is processed international standard machine swaging clamp sheet and PCBN cutter grain after welding.
The utility model solves the technical scheme that the process technology problem is taked: a kind of PCBN blade that is used for special-shaped screw thread processing, and an end of machine swaging clamp sheet and PCBN cutter grain are welded to connect; The top of PCBN cutter grain is made up of main cutting edge and preparatory cutting blade.
The both sides of main cutting edge are preparatory cutting blade of left feeding and the preparatory cutting blade of right feeding, and main cutting edge is that arc transition is connected with preparatory cutting blade of left feeding and the preparatory cutting blade of right feeding.
Connect together international standard machine swaging clamp sheet and PCBN cutter grain mode with high-frequency welding; Carry out roughing through the discharge moulding earlier, adopt grinding method to carry out fine finishining then; Through increasing the cutting output that two preparatory cutting edges reduce main cutting edge, can prolong the service life of cutter greatly.
The high rigidity of characteristics of the utility model and advantage: PCBN, high-wearing feature, high temperature tolerance make it to compare with sintered-carbide tool and have the longer life-span; PCBN cutter grain is connected with the hard alloy substrate of high tenacity, thereby improves the overall performance of this product; Two preparatory cutting blades that increase can effectively reduce the impact to main cutting edge that causes because of the raw material chipping allowance is irregular; The international standard carbide alloy machine swaging clamp sheet matrix scope of application is wider, and batch process is faster delivery date.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, wherein:
Fig. 1 is the structural representation of expression as the utility model embodiment.
Fig. 2 is to the partial structurtes sketch map of the utility model.
The specific embodiment
Embodiment with reference to Fig. 1,2 pairs of the utility model describes.
Embodiment: like Fig. 1, shown in 2;
The utility model provides a kind of PCBN blade that is used for special-shaped screw thread processing, and an end of machine swaging clamp sheet 1 and PCBN cutter grain 2 are welded to connect; The top of PCBN cutter grain 2 is made up of main cutting edge 5 and preparatory cutting blade, and the both sides of main cutting edge 5 are preparatory cutting blade 6 of left feeding and the preparatory cutting blade 6 of right feeding, and main cutting edge 5 is connected for arc transition with the preparatory cutting blade 4 of right feeding with the preparatory cutting blade 6 of left feeding.
The top of PCBN cutter grain 2 is special-shaped screw thread form.
Obviously, the many modifications made based on the aim of the utility model of those skilled in the art and the variation protection domain that belongs to the utility model.
As stated, the embodiment of the utility model has been carried out explanation at length, but as long as break away from the inventive point and the effect of the utility model in fact a lot of distortion can not arranged, this will be readily apparent to persons skilled in the art.Therefore, such variation also all is included within the protection domain of the utility model.
