Abstract
A welded carbide-tipped reamer for processing titanium alloy is a change to angle of a cutting edge of a welded carbide-tipped reamer for processing titanium alloy. The welded carbide-tipped reamer comprises a reamer front guide, a reamer cutting edge portion, a reamer rear guide and a reamer handle, and is characterized in that a clearance angle of the cutting edge on the reamer cutting edge portion is 14 degrees, an rake angle of the cutting edge on the reamer cutting edge portion is -13 degrees, and bandwidth of a cylinder cutting edge on a calibrating portion on the reamer cutting edge portion is 0.15-0.2mm. The welded carbide-tipped reamer has the advantages that because the clearance angle and the rake angle of the cutting edge are increased and the band width of the cylinder cutting edge of the calibrating portion on the reamer cutting edge portion is reduced, the cutting edge is sharpened while the cutting resistance and the cutting edge abrasion are reduced, and then cutting performance of the carbide-tipped reamer for processing titanium alloy is increased, processing efficiency is increased correspondingly and service life of the carbide-tipped reamer is prolonged.
Description
Technical field: the invention is the change to the carbide-tipped reamer cutting edge profile of machining titanium alloy.
Background technology: titanium alloy has ratio of strength to weight height, plurality of advantages such as high-temperature behavior is good, in the Aero-Space manufacturing industry, be employed more and more widely, but, titanium alloy is again a kind of material processed of tieing up very much, its main cause is because poor thermal conductivity, elastic modelling quantity is little, therefore, the material cutting ability is poor, bigger to tool wear, especially the bounce-back of surface to be machined material is bigger, make that the cutter wear of the tool flank is very fast, and existing machining titanium alloy carbide-tipped reamer is because main structure parameters cutting edge anterior angle is less, numerical value is-15 °, the cutting edge relief angle is less, numerical value is 10 °, the cylinder margin width of the calibrated section on the reamer blade is too big again, numerical value is 0.2～0.25mm, makes cutting resistance increase, and is easy to generate vibration during cutting, the precision and the roughness in processed hole have not only been reduced, but also having aggravated the wearing and tearing of cutter, one of existing machining titanium alloy carbide-tipped reamer can only be processed several holes at most, and, the cutting feed speed of cutter is very low, has caused existing machining titanium alloy carbide-tipped reamer cutting ability poor, working (machining) efficiency is low, the easily overproof and short shortcoming of cutter life of processed pore volume.
Summary of the invention: the purpose of the invention provides a kind of machining titanium alloy that reduces cutting resistance, reduces the cutting edge wearing and tearing and welds carbide-tipped reamer; The purpose of the invention is to realize by following technical scheme: machining titanium alloy welding carbide-tipped reamer, guide and the reamer shank after comprising the preceding guiding of reamer, reamer blade, reamer, it is characterized in that the cutting edge relief angle on the reamer blade makes 14 °, cutting edge anterior angle on the reamer blade is made-13 °, and the cylinder margin width of the calibrated section on the reamer blade is made 0.15～0.2mm.
The advantage of the invention: because the cutting edge anterior angle is strengthened, make-13 °, the cutting edge relief angle is strengthened, make 14 °, the cylinder margin width of the calibrated section on the reamer blade is reduced, make 0.15～0.2mm, make cutting edge become sharp, cutting resistance reduces, the cutting edge wearing and tearing reduce, thereby improved cutting ability to the carbide-tipped reamer of titanium alloy fraising processing, improve working (machining) efficiency, and prolonged the service life of carbide-tipped reamer.
Description of drawings:
Fig. 1 is a machining titanium alloy welding carbide-tipped reamer structural representation;
Fig. 2 is along B-B line generalized section among Fig. 1;
Fig. 3 is along A-A line generalized section among Fig. 1.
Among the figure: 1, guide 4 before the reamer behind guiding 2, reamer blade 3, the reamer, reamer shank 5, cutting edge relief angle 6, cutting edge anterior angle 7, cylinder margin width
The specific embodiment: machining titanium alloy welding carbide-tipped reamer, guide and the reamer shank after comprising the preceding guiding of reamer, reamer blade, reamer, it is characterized in that the cutting edge relief angle on the reamer blade makes 14 °, cutting edge anterior angle on the reamer blade is made-13 °, and the cylinder margin width of the calibrated section on the reamer blade is made 0.15～0.2mm.
Advantage: because the cutting edge anterior angle is strengthened, make-13 °, the cutting edge relief angle is strengthened, make 14 °, the cylindrical edge bandwidth of the calibrated section on the reamer blade is reduced, make 0.15～0.2mm, so that cutting edge becomes sharp, cutting resistance reduces, the cutting edge wearing and tearing reduce, thereby improved cutting ability to the carbide-tipped reamer of titanium alloy fraising processing, improve accordingly working (machining) efficiency, and prolonged the service life of carbide-tipped reamer.
