Abstract
The utility model relates to a left spiral integral hard alloy taper reamer comprising a cutting part (1) and a handle (2), wherein, the front angle gamma of the cutting part (1) ranges from 3 to 8 degrees, the rear angle alpha of the cutting part ranges from 10 to 15 degrees, and the leftwards screwed spiral angle ranges from 5 to 10 degrees. The reamer changes the traditional cutter angle, solves problems in reaming titanium alloy or stainless steel taper holes, not only enhances the cutter endurability, but also improves the brightness of a part processing surface.
Description
Technical field
The utility model relates to a kind of left-hand screw whole hard alloy tapering reamer, is processing stainless steel tapering hole type parts left-hand screw solid carbide reamer.
Background technology
Titanium alloy, stainless steel material is widely used in aviation, shipbuilding, every field such as medical treatment.Especially at aircraft industry, still, titanium alloy, Machinability of Stainless Steel is relatively poor, and finished surface luminosity is poor.There is not machining titanium alloy in GB, navigation mark, the enterprise's mark, the stainless steel tapering hole type parts standard of left-hand screw solid carbide reamer.Aborning, the processing steel part is with straight-tooth high-speed steel tapering reamer, and this kind cutter is used for machining titanium alloy, and during stainless steel material, shortcoming is that anterior angle γ=0 ° Tool in Cutting is not sharp, the character of titanium alloy, stainless steel material be glue, poor thermal conductivity, sticking easily cutter.Relief angle α=10 ° shortcoming is that the springback capacity of titanium alloy, stainless steel material is big, knife face friction increase behind part material and the cutter when causing the machining titanium alloy, titanium alloy, the stainless steel heat dispersion when cutting is poor, simultaneously because friction causes the cutting temperature can be higher, also because frictional force has also increased cutting resistance.Helical angle ω=0 °, the agglomerating smear metal of smear metal meeting is not easily broken, is wrapped in the processing district easily, and the chip removal difficulty causes machined surface luminosity defective, perhaps causes vexed car that processing can't be carried out because smear metal is twined.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of left-hand screw whole hard alloy tapering reamer, this reamer has changed traditional cutting-tool angle, solved the fraising problem of titanium alloy, stainless steel tapering hole type parts, not only improve the durability of cutter, and improved the luminosity on part processing surface.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of left-hand screw whole hard alloy tapering reamer, form the anterior angle γ of cutting tip=3～8 ° by cutting tip and handle, relief angle α=10～15 °, the left-handed ω of helical angle=5～10 °.
Described reamer material is a whole hard alloy.
Described reamer margin width is f=0.03～0.08mm.
The structural member of titanium alloy, stainless steel material is a part important on the aircraft, and the tapered hole part processing is also occupied certain ratio.The utility model adopts said structure to have general applicability, solved the fraising problem of titanium alloy, stainless steel material tapering hole type parts, in the design of tool structure parameter and geometric parameter, carried out innovative design, the durability of cutter is improved greatly, improved these two kinds of material parts finished surface luminosity and satisfied the production demand.Machining titanium alloy, stainless steel tapering hole type parts left-hand screw solid carbide reamer adopts the whole hard alloy material, on the numerical control knife sharpener, processes, a coding, repeatedly processing can guarantee the cutter quality of stability, improves the quality of products.
Description of drawings
Fig. 1 is the front view of left-hand screw whole hard alloy tapering reamer.
Fig. 2 is A-A cutaway view of Fig. 1.
The specific embodiment
As shown in Figure 1, 2, a kind of left-hand screw whole hard alloy tapering reamer is made up of cutting tip 1 and handle 2, the anterior angle γ of cutting tip 1=3～8 °, relief angle α=10～15 °, the left-handed ω of helical angle=5～10 °.
Described reamer material is a whole hard alloy.
Described reamer margin width is f=0.03～0.08mm.
The selection of cutter material: machining titanium alloy, the cutter of stainless steel material is selected the whole hard alloy bar, reason is that carbide alloy is the sintered metal product that forms of sintering at high temperature, has higher hardness, 850～1000 ℃ of high temperature of ability, have good wearability and hear resistance and hardness, so its cutting speed improves 2～3 times than high-speed steel tool, thereby enhance productivity.
The selection of geometric parameter: 1) anterior angle is main cutting edge anterior angle γ=3～8 °, keeps cutter sharp, helps the chip breaking chip removal simultaneously.Simultaneously, reduce the heat resistanceheat resistant performance that the main smear metal basil can also strengthen cutting edge rigidity and cutting edge, avoided 0 ° of Tool in Cutting of anterior angle not sharp again, the sticking serious phenomenon of cutter, the influence cutting is normally carried out, and its best angle is 5 °.2) effect of relief angle α=10～15 ° mainly is the friction that reduces back knife face and cutting surface, guarantee that simultaneously cutting teeth has enough cutting hardnesses, adopting relief angle α=12 ° be optimum, advantage be because of the springback capacity of titanium alloy material big, the increase of relief angle has reduced the machining titanium alloy, stainless steel is knife face friction behind part material and the cutter, help titanium alloy, the heat dispersion of stainless steel material when cutting, reduce the cutting temperature that friction causes, reduced the cutting resistance that causes because of frictional force, simultaneously, the increase of relief angle helps the inflow of cutting fluid, makes to cool off in the process fully, reduce cutting temperature, improve the durability of reamer.3) effect of helical angle ω=5～10 ° is intensity, cutting component and the chip removal direction that influences working portion, and the left-handed ω of helical angle=7 ° be the best.The spirality reamer can be avoided screens phenomenon and the sword tooth phenomenon of bursting apart, and energy is brisk, steady, tool life is also higher, and can further guarantee the treatment of surfaces of components fineness, the left-hand screw sword can be controlled the chip-flowing green surface, has improved this two kinds of material parts finished surface luminosity.
The margin width of reamer also is an important step in the reamer designing, and the land of reamer mainly plays guiding, and the extruding hole wall is measured effects such as reamer diameter.Margin width can not be excessive, crosses conference the friction between reamer and the hole wall is increased, and increases cutting power; Too small meeting reduces the reconditioning number of times, selects f=0.05mm.
