Abstract
The utility model relates to a threaded handle stepped reamer for machining titanium alloy. The threaded handle stepped reamer comprises a cutting blade part and a reamer handle part, wherein the cutting blade part comprises a first stepped cutting blade, a second stepped cutting blade and a third stepped cutting blade from the bottom up, the front angle of each reamer cutting blade is 1-3 degrees, the back angle of each reamer cutting blade is 10-12 degrees, and the diameters of the stepped cutting blades are gradually increased; one end of the reamer handle part is a polygonal cylinder body and is connected with the end parts of cutting blade parts, the other end of the reamer handle part is an outer thread, and the outer thread is connected with the polygonal cylinder body through a tool withdrawing groove and a conical surface. According to the threaded handle stepped reamer for machining the titanium alloy, which is disclosed by the utility model, the cutting machining performance of the reamer is improved, the reaming machining quality is good, and the efficiency is high.
Description
Technical field
The utility model relates to a kind of machining titanium alloy thread handle Stepped Reamers, for the fraising processing of titanium alloy member.
Background technology
Although titanium alloy has the plurality of advantages such as the ratio of strength to weight is high, corrosion-resistant and is used in more and more widely in Aero-Space manufacturing industry,, titanium alloy belongs to typical difficult processing aeronautical material, especially under the condition of non-unlimited processing space.At present, each titanium alloy hole needs three existing thread handle Stepped Reamers, and the shank of reamer is without orientational cone-shaped surface.Finally, cause that existing machining titanium alloy thread handle Stepped Reamers working (machining) efficiency is low, machining accuracy is poor and the defect such as cutter easy fracture, therefore, be difficult to meet the requirement of high-quality and efficient titanium alloy fraising processing.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of machining titanium alloy thread handle Stepped Reamers, and this machining titanium alloy thread handle Stepped Reamers has improved the machinability of reamer, is that the quality of fraising processing is good, and efficiency is high.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of machining titanium alloy thread handle Stepped Reamers, comprise cutting blade and reamer shank, cutting blade is followed successively by the first ladder cutting edge, the second ladder cutting edge and the 3rd ladder cutting edge from the bottom to top, the anterior angle of each reamer cutting edge is 1 °～3 °, relief angle is 10 °～12 °, and the diameter of ladder cutting edge increases progressively gradually; One end of reamer shank be polygon cylinder and with cutting blade end be connected, the other end of reamer shank is external screw thread, external screw thread is connected with polygon cylinder with taper surface by escape.
The below of described cutting blade is also provided with guide portion.
The cone angle of described taper surface is 120 °.
This machining titanium alloy thread handle Stepped Reamers adopts said structure, is equivalent to the function synthetic of three reamers on reamer, has greatly shortened the time of fraising processing, and three synthesize a reamer reamer, its positioning precision is high, crudy is good, and efficiency is high; At reamer shank, a paniculidine plane is set, to improve positioning precision and the bonding strength between cutter and instrument.
Accompanying drawing explanation
Fig. 1 is the front view of machining titanium alloy thread handle Stepped Reamers.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the partial view of reamer shank.
The specific embodiment
As shown in Figure 1 to Figure 3, a kind of machining titanium alloy thread handle Stepped Reamers, comprise cutting blade 10 and reamer shank 5, cutting blade 10 is followed successively by the first ladder cutting edge 2, the second ladder cutting edge 3 and the 3rd ladder cutting edge 4 from the bottom to top, the anterior angle 6 of each reamer cutting edge is 2 °, relief angle 7 is 11 °, and the diameter of ladder cutting edge 3 increases progressively gradually, wherein the diameter of the first ladder cutting edge 2 is 5.8 mm H5, the diameter of the second ladder cutting edge 3 is 5.9mmH5, and the diameter of the 3rd ladder cutting edge 4 is 6mmH5; One end of reamer shank 5 be polygon cylinder and with cutting blade 10 end be connected, the other end of reamer shank 5 is external screw thread, external screw thread is connected with polygon cylinder with taper surface 8 by escape.The below of described cutting blade 10 is also provided with guide portion 1.The cone angle of described taper surface is 120 °.
