Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1, a kind of combination forming cutter, comprises handle of a knife 1 and cutter hub 2, and shank diameter d is (25-0.015) ~ (25-0.002) mm, and long L is 55mm.Described cutter hub comprises segment of cutting and combined segment, step transition between two sections, and this step is obliquely installed, and is provided with reaming blade A3 at this tilt stage place.
The head end of described segment of cutting is provided with point of a knife 5, and point of a knife angle α is 120 °, is convenient to locate the centering in hole, and cutting segment length L4 is 55mm.Segment of cutting is provided with 3 steps, segment of cutting is divided into 4 sections, and every section is provided with a step plane 4, from point of a knife, be respectively first step, second step, the 3rd step, first paragraph, second segment, the 3rd section, the 4th section, inclined plane transition between every section, is respectively the first inclined plane, the second inclined plane, the 3rd inclined plane.3 inclined plane size C1, C2, C3 are followed successively by 1mm, 1.5mm, 1.5mm, and inclined plane and cutter hub axis angle α 1, α 2, α 3 are followed successively by 45 °, 20 °, 20 °.Diameter d 1, d2, d3, d4 of 4 sections are followed successively by (8-0.01) ~ (8+0.01) mm, (11.7-0.01) ~ (11.7+0.01) mm, (16.7-0.01) ~ (16.7+0.01) mm, 20 ~ (20+0.01) mm, length L1, L2, L3 are followed successively by 4.5mm, 13.5mm, 13.5mm, the distance L5 of the 3rd the aforementioned tilt stage of step distance is 37mm.
Described combined segment is provided with 1 step, this step is obliquely installed, and establish reaming blade B6 at this tilt stage place, between this tilt stage and aforementioned tilt stage, spacing L6 is 24mm, and the diameter d 5 of cutter hub is 24 ~ (24+0.01) mm between two tilt stages, between this inclined plane and handle of a knife, spacing L7 is 30mm, and cutter hub diameter d 6 is (25.5+0.02) ~ (25.5+0.03) mm between the two.
Described cutter hub is provided with 1 chip area A7 and at least 2 chip area B8, the afterbody arc-shaped transition of chip area A is also crossing with the outer circumference surface of segment of cutting, the stem arc-shaped transition of chip area B is also crossing with the outer circumference surface cut, the afterbody arc-shaped transition of chip area B is also crossing with the outer circumference surface of combined segment, the setting alternate with chip area B of described reaming blade, described chip area B is provided with the oil outlet 9 corresponding with reaming blade, the axial location of handle of a knife and cutter hub is provided with center oil outlet 10, center oil outlet diameter D is 3mm, and oil outlet is connected with center oil outlet.The cross sectional shape of described reaming blade for the cross sectional shape of reaming blade described in L shape be L shape, chamfered transition between the sword face of L shape reaming blade A, chamfering C is 0.5mm, and inclined plane transition between the sword face of sword face L shape reaming blade B, inclined plane and cutter hub axis angle β are 59 °.
Cutter hub is arranged to segment of cutting and combined segment, is first cut by chip section, then carries out ream operation by the reaming blade of combined segment.Cornish bit place step is obliquely installed, and cornish bit structure corresponds to tilt stage and arranges, and tilt stage can arrange cutting edge, thus realize limit spiral cutting limit reaming, reduces reaming difficulty, improves reaming progress.Reaming blade is welded on cutter hub, when reaming blade is impaired, can direct more allowing blade replacement, and improve production efficiency.Adopt the utility model, the disposable machine-shaping of workpiece, simplifies complicated manufacturing procedure, avoids the problems such as the machining accuracy that causes is low because changing that different cutter carries out processing in the past, make cooler realize being connected with good between other parts, improve machining accuracy simultaneously.Combination forming cutter can heat up in the process high speed rotation of machining hole, the setting of oil outlet and center oil outlet, not only can lubricated blades, but also can reduce combination forming cutter temperature, and then improves the physical life of combination forming cutter.
