Abstract
Hard alloy expanding drill for processing titanium alloy is an improvement of a hard alloy blade expanding drill structure for expanding holes on titanium alloy materials, which overcomes the shortcomings that high speed steel type expanding drills and hard alloy expanding drills for processing steel members can not process the titanium alloy. The hard alloy expanding drill for processing titanium alloy comprises a front guider, a cutting body and a drill shank, wherein the cutting body is formed by a drilling body and a blade, the front angle of the blade in the cutting body is processed in 0-3 degrees, the rear angle of the blade is processed in 12-14 degrees, the inclination angle is processed to be larger than 0-7 degrees, and a rear guider is arranged between the cutting body and the drill shank. The hard alloy expanding drill for processing titanium alloy has the advantages of reducing friction, reducing cutting temperature, prolonging the service life of the expanding drill, and meeting the technical requirements upon processing titanium alloy expanding holes.
Description
Technical field:
The invention is the improvement of carbide chip reamer structure that reaming on titanium alloy material is used.
Background technology:
It is little that titanium alloy material has density, the intensity height, and specific strength substantially exceeds high strength steel, the heat resistance height, corrosion resistance is good, so the every field of being widely used in.But the machinability of titanium alloy is relatively poor, poor thermal conductivity, present existing its blade anterior angle of high-speed steel class reamer is 5 degree, relief angle is 8 degree, and cutting edge inclination is the 15-20 degree, and its blade anterior angle of carbide alloy reamer is-15 degree, relief angle is 10 degree, cutting edge inclination is 0 degree, during with above-mentioned reamer machining titanium alloy material, when anterior angle is-15 when spending, negative rake is extrusion process, during the titanium alloy material extrusion process, form the flow harden layer, can't realize cutting, the character of titanium alloy material is sticking, poor thermal conductivity, negative rake adds man-hour, and cutter can not cut down bits, and only rotation forms the flow harden layer in the original place.When anterior angle is 5 when spending, anterior angle is too big, and edge strength is not enough, and simultaneously because the cutting temperature of titanium alloy is 2 times of 45 steel, promptly the heat dispersion of titanium alloy material when cutting is poor, and the temperature of point of a knife part is too high, and wearing and tearing have easily reduced blade service life.When relief angle is that 8 degree, 10 are when spending, because of the titanium alloy material springback capacity big, knife face friction increase behind part material and the cutter when causing the machining titanium alloy, the heat dispersion of titanium alloy material when cutting is poor, simultaneously because friction causes the cutting temperature can be higher, also because frictional force has also increased cutting resistance, above reason all is unfavorable for the machining titanium alloy material.When cutting edge inclination is that 15-20 is when spending, cutting edge inclination is too big, and blade forms the single-point cutting, and cutting resistance causes the edge strength of blade poor greatly, the service life that easy tipping has reduced blade, when cutting edge inclination is 0 when spending, cutting edge inclination is too little, and axial force is big during blade cut, frictional force is big, and be interrupted processing, having strengthened cutting resistance especially for tough titanium alloy material processing, cutting ability is poor.
Summary of the invention:
The purpose of the invention provides a kind ofly carries out reaming and adds and can reduce the temperature that produces because of cutting man-hour on titanium alloy material, prolong the blade machining titanium alloy carbide alloy reamer in service life; The purpose of the invention is achieved through the following technical solutions: machining titanium alloy carbide alloy reamer, comprise preceding guiding, cutting body, back guiding, drillstock, cutting body is made of drill body, blade, blade anterior angle in the cutting body is made the 0-3 degree, relief angle is made the 12-14 degree, and cutting edge inclination is made greater than 0 degree to 7 degree.
The advantage of the invention: the 0-3 degree is made at the anterior angle angle, increased the intensity of point of a knife part, avoided negative rake that titanium alloy material is added and formed the flow harden layer man-hour, improved the service life of cutter; Relief angle is made the 12-14 degree, relief angle increases, and knife face friction behind part material and the cutter when having reduced the machining titanium alloy helps the heat dispersion of titanium alloy material when cutting, reduce the cutting temperature that friction causes, reduced the cutting resistance that causes because of frictional force; Cutting edge inclination is made greater than 0 degree to 7 degree, and axial force reduces during Tool in Cutting, and the frictional force during tool feeding is little and be continuous processing, for tough titanium alloy material processing having reduced especially cutting force, cutting ability is improved, owing to make the back guiding, has improved the reaming precision.
Description of drawings:
Fig. 1 is a machining titanium alloy carbide alloy reamer structural representation;
Fig. 2 is an A-A sectional drawing among Fig. 1.
Among Fig. 1 Fig. 2,1 preceding guiding, 2 cutting bodies, 3 back guiding, 4 drillstocks, 5 drill bodies, 6 blades, the γ anterior angle, the α relief angle, the R back of tooth is led fillet.
The specific embodiment:
Machining titanium alloy carbide alloy reamer, comprise preceding guiding, cutting body, back guiding, drillstock, cutting body is made of drill body, blade, blade anterior angle in the cutting body is made the 0-3 degree, relief angle is made the 12-14 degree, cutting edge inclination is made greater than 0 and spend to 7 degree guiding after making between cutting body and drillstock.Have preceding guiding, cutting body, back guiding, the drillstock structure is conventional reamer, make preceding guiding before and after the cutting body, the back guiding can improve the reaming precision, when selecting the carbide cutter tool sheet material for use, select yg-type carbide, all contain WC and CO, do not contain the material that very big compatibility is arranged with titanium alloy, therefore can improve the cutter wearability; Anterior angle γ makes the favourable chip breaking chip removal of 0-3 degree, reduce the main cutting edge anterior angle number of degrees, can also strengthen the heat resistanceheat resistant performance of cutting edge rigidity and cutting edge, significantly improve the durability of reamer, relief angle α makes the 12-14 degree, reduce the friction of back knife face and cutting surface, guarantee that cutting tip has enough cutting hardnesses, cutting edge inclination is made greater than 0 degree to 7 degree, reduced cutting resistance, cutting ability is improved, and has increased the back of tooth fillet R bulk smear metal is discharged easily, the size of back of tooth fillet R is selected according to the diameter of cutter, be about 1/4th of diameter, for example: the reamer of Φ 20mm diameter, back of tooth fillet R=5mm, the reamer of Φ 12mm diameter, back of tooth fillet R=3mm.
