Abstract
The utility model relates to a kind of integral sintered PCBN blade for processing profiled screw thread, belongs to sintered carbide tools technical field.For an integral sintered PCBN blade for processing profiled screw thread, described integral sintered PCBN blade has at least two cutting edges, and cutting edge is made up of main cutting edge and pre-cutting edge.Relative to prior art, the utility model processes at least two cutting edges on PCBN blade, adds the service life of blade, and the buying reducing company drops into, and adopts integral sintered PCBN blade, solves the caducous problem of cutter grain.
Description
Technical field
The utility model relates to a kind of integral sintered PCBN blade for processing profiled screw thread, belongs to sintered carbide tools technical field.
Background technology
In prior art, the machining tool of abnormal screw thread is based on carbide alloy, find in retrieval that application number is the PCBN blade that 201120292658.6(mono-kind processes for abnormal screw thread) patented product, also be the processing for abnormal screw thread, but blade is the PCBN cutter grain of welding, the cutter grain of welding easily comes off from cutter hub, and PCBN cutter grain is just welded on one end of cutter hub, and blade is shorter for service life.
Utility model content
The technical problems to be solved in the utility model is that the existing PCBN blade cutter grain for abnormal screw thread processing easily comes off, and service life is short, for solving the problem, provides a kind of integral sintered PCBN blade for processing profiled screw thread.
The purpose of this utility model realizes in the following manner:
For an integral sintered PCBN blade for processing profiled screw thread, described integral sintered PCBN blade has at least two cutting edges, and cutting edge is made up of main cutting edge and pre-cutting edge.
The both sides of described main cutting edge are the pre-cutting edge of left feeding and the pre-cutting edge of right feeding.
Described main cutting edge and the pre-cutting edge of left feeding and the pre-cutting edge of right feeding are circular sliding slopes, and the radius of circular arc is R, 5mm≤R≤15mm.
Cutting edge shape and the abnormal screw thread matching form of described integral sintered PCBN blade close.
Described integral sintered PCBN blade shapes is triangle, square, rhombus or regular hexagon.
Relative to prior art, the utility model processes at least two cutting edges on PCBN blade, adds the service life of blade, and the buying reducing company drops into, and adopts integral sintered PCBN blade, solves the caducous problem of cutter grain.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is Fig. 1 side view.
Fig. 3 is Fig. 1 I enlarged drawing.
Wherein, 1 is the pre-cutting edge of left feeding; 2 is main cutting edges; 3 is the pre-cutting edges of right feeding.
Detailed description of the invention
As shown in Figure 1-Figure 3
,for an integral sintered PCBN blade for processing profiled screw thread, described integral sintered PCBN blade has at least two cutting edges, and cutting edge is made up of main cutting edge 2 and pre-cutting edge.The both sides of described main cutting edge 2 are the pre-cutting edge of left feeding 1 and the pre-cutting edge 3 of right feeding.Described main cutting edge 2 is circular sliding slopes with the pre-cutting edge of left feeding 1 and the pre-cutting edge 3 of right feeding, the radius of circular arc is R, the size of 5mm≤R≤15mm, R can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, 11mm, 12mm, 13mm, 14mm, 15mm.Cutting edge shape and the abnormal screw thread matching form of described integral sintered PCBN blade close.Described integral sintered PCBN blade shapes is triangle, square, rhombus or regular hexagon.
The beneficial effects of the utility model: the high rigidity of PCBN blade, high-wearing feature, high temperature tolerance, make it that there is the longer life-span compared with sintered-carbide tool, at blade processing at least two cutting edges, improve the service life of blade, the buying decreasing company drops into; Increase by two pre-cutting edges and effectively can reduce the impact to main cutting edge caused because raw material chipping allowance is irregular.
