Abstract
The utility model relates to a boring cutter blade for processing a wheel hub. The end face of the boring cutter blade is rhombic, the middle of the boring cutter blade is provided with mounting holes, a cutting part is inlaid in the end face of one side of the acute angle part of the boring cutter blade in a welding manner, and the outer side face of the cutter point of the cutting part is provided with a burnishing blade; and the angle of the burnishing blade of the cutting part is 6 degrees. The boring cutter blade for processing the wheel hub reduces sand holes of a processed workpiece and increases the appearance effect as well as the product quality of the workpiece.
Description
Technical field
The utility model relates to the Machining Technology field, particularly a kind of boring cutter sheet of processing wheel hub.
Background technology
Be used to process the boring cutter that wheel hub is used, the boring cutter sheet that adopts is that end face is the blade of rhombus at present, the middle part of boring cutter sheet is provided with the installing hole that is used for fixing, pass through solder flux welding-on cutting tip on one side end face of the acute angle rib 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 the cutting tip side is the right angle, adding the man-hour impulsive force concentrates and bigger, the surface of the work of processing is more coarse, and be easy to generate sand holes on the workpiece, influence the appearance and the product quality of workpiece.
The utility model content
The utility model purpose is to provide a kind of boring cutter sheet of processing wheel hub, can reduce the sand holes of processing work, improves the appearance and the product quality of workpiece.
To achieve these goals, the utility model adopts following technical scheme: the boring cutter sheet of processing wheel hub, and boring cutter sheet end face is a rhombus, the middle part of boring cutter sheet is provided with installing hole, welding-on is provided with cutting tip on one side end face of the acute angle of boring cutter sheet, and cutting tip point of a knife lateral surface is provided with the burnishing-in sword.
The burnishing-in basil degree of described cutting tip is 6 °.
The utility model reduces the sand holes that processing work produces, and improves the appearance and the product quality of processing work.Cutting tip has characteristics such as hardness height, compression strength height, thermal conductivity and wearability are good, but high-speed cutting can obtain very high manufacturing accuracy, improves working (machining) efficiency.
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 the A place structure for amplifying schematic diagram of Fig. 1.
The specific embodiment
Embodiment: as Fig. 1, Fig. 2, shown in Figure 3, the boring cutter sheet of processing wheel hub, boring cutter sheet end face is a rhombus, the middle part of boring cutter sheet is provided with installing hole 2, welding-on is provided with cutting tip 1 on one side end face of the acute angle of boring cutter sheet, cutting tip 1 point of a knife lateral surface is provided with the burnishing-in sword, and the burnishing-in sword angle [alpha] of cutting tip is 6 °.
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. process the boring cutter sheet of wheel hub, it is characterized in that: boring cutter sheet end face is a rhombus, and the middle part of boring cutter sheet is provided with installing hole, and welding-on is provided with cutting tip on the side end face of the acute angle of boring cutter sheet, and cutting tip point of a knife lateral surface is provided with the burnishing-in sword.
2. the boring cutter sheet of processing wheel hub according to claim 1 is characterized in that: the burnishing-in basil degree of described cutting tip is 6 °.
