Abstract
The utility model relates to a boring blade for processing a camshaft hole. The section of a boring blade is trapezoidal; a cutting part is inlaid and welded on the upper side surface of the edge position at one end of the boring blade; one side of a knife point of the cutting part is provided with two sections of amelioration blades; and amelioration angles alpha and beta of the two sections of amelioration blades are respectively equal to 10-15 degrees and 70-80 degrees. The utility model has simple structure and practical function, is difficult to scratch a workpiece and improves the quality of products.
Description
Technical field
The utility model relates to the Machining Technology field, particularly a kind of boring cutter sheet of machining cam axis hole.
Background technology
Be used for the boring cutter that the machining cam axis hole is used, the boring cutter sheet that adopts is that the cross section is trapezoidal blade at present, the top of boring cutter sheet is provided with the two holddown grooves that are used for fixing, pass through solder flux welding-on cutting tip on the upper side of one end edges and corners of boring cutter sheet, cutting tip mainly is the composite sheet of polycrystalline diamond (or polycrystalline cubic boron nitride), its composite sheet is that polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer form through the HTHP compacting, because side, cutting tip top is the right angle face, adding the man-hour impulsive force concentrates and bigger, scratch workpiece easily, the workpiece accuracy of processing is not high, influences the product quality of workpiece.
The utility model content
The utility model purpose is to provide a kind of boring cutter sheet of machining cam axis hole, can improve the precision of processing work, thereby improves the product quality of workpiece.
To achieve these goals, the utility model adopts following technical scheme: a kind of boring cutter sheet of machining cam axis hole, boring cutter sheet cross section is trapezoidal, welding-on cutting tip on the upper side of end edges and corners of boring cutter sheet, and cutting tip point of a knife one side is provided with two sections wiper edges that are connected mutually.
The smoothing angle of described two sections wiper edges is respectively α=10 °～15 ° and β=70 °～80 °.
The utility model is simple in structure, function is practical, is not easy to scratch workpiece, has improved the quality of product.Cutting tip has characteristics such as hardness height, compression strength height, thermal conductivity and wearability are good, but high-speed cutting obtains very high manufacturing accuracy working (machining) efficiency.Two sections wiper edges have effectively improved the precision of workpiece to be machined.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a vertical view of the present utility model;
Fig. 3 is a left view of the present utility model.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, a kind of boring cutter sheet of machining cam axis hole, boring cutter sheet cross section is trapezoidal, welding-on cutting tip 1 on the upper side of end edges and corners of boring cutter sheet, cutting tip 1 point of a knife one side is provided with two sections wiper edges that are connected mutually.The smoothing angle of two sections wiper edges is respectively α=10 °～15 ° and β=70 °～80 °.
Cutting tip mainly is the composite sheet of polycrystalline diamond (or polycrystalline cubic boron nitride), its composite sheet is that polycrystalline diamond layer (or polycrystalline cubic boron nitride layer) and hard alloy layer form through the HTHP compacting, PCD (polycrystalline diamond) material mainly contains following characteristics: 1. PCD hardness can reach 8000HV, is 80～120 times of carbide alloy; 2. the PCD thermal conductivity factor is 700W/mK, be 1.5～9 times of carbide alloy, even be higher than PCBN, copper, so the transmission of PCD cutter heat is rapid; 3. the PCD coefficient of friction generally only is 0.1～0.3 (the carbide alloy coefficient of friction is 0.4～1), so the PCD cutter can significantly reduce cutting force; 4. the PCD thermal coefficient of expansion only is 0.9 * 10-6～1.18 * 10-6, only is equivalent to carbide alloy 1/5, so the thermal deformation of PCD cutter is little, the machining accuracy height; 5. affinity is very little between PCD cutter and non-ferrous metal, nonmetallic materials, and the process smear metal is difficult for bonding and forms built-up edge.
Claims (2)
1. the boring cutter sheet of a machining cam axis hole, it is characterized in that: boring cutter sheet cross section is trapezoidal, welding-on cutting tip on the upper side of end edges and corners of boring cutter sheet, cutting tip point of a knife one side is provided with two sections wiper edges that are connected mutually.
2. the boring cutter sheet of machining cam axis hole according to claim 1 is characterized in that: the smoothing angle of described two sections wiper edges is respectively α=10 °～15 ° and β=70 °～80 °.
