Definitions
- the present invention relates to a drill particularly suitable for processing an FRP (fiber reinforced plastics. Composite material of reinforcing fiber and resin matrix) and a metal laminate.
- FRP fiber reinforced plastics. Composite material of reinforcing fiber and resin matrix
- CFRP Carbon Fiber Reinforced Plastics
- This CFRP may be provided as a plate material having a composite structure in combination with a relatively viscous metal such as aluminum or titanium.
- a metal plate is used on one surface of CFRP (hereinafter simply referred to as a “stacked plate”).
- CFRP CFRP
- stacked plate For example, when forming the fuselage or wing of an airplane, it is necessary to make a hole through which a fastening material such as a bolt or a rivet passes.
- the drill of Patent Document 1 has a cutting edge symmetrical to the rotation center from the rotation center to the outer periphery at the tip of the main body, and the cutting edge is at least the rotation center, the intermediate blade connected to the outer end, and the intermediate blade It is composed of three parts of a linear outermost peripheral blade part connected to the outer end, and the tip angle of each blade part is gradually reduced from the rotation center side to the outer peripheral blade part.
- the metal layer can be processed from the top so that the thrust load that is disliked by processing of a single FRP material can be received by the metal layer. For this reason, a hole that satisfies the required quality can be formed even by processing with a standard blade type drill, but this standard blade type drill has a short life and cannot improve productivity.
- the drill of Patent Document 1 makes it possible to process so-called burrs, fluff, flaking, and high-quality holes with less chipping by reducing the thrust applied to the cutting edge on the outer diameter side. ing.
- This invention makes it a subject to provide an effective drill as a solution of the said subject.
- the drill is used for drilling FRP and a metal stack, and has a cutting edge symmetrical to the rotation center from the rotation center to the outer periphery at the tip of the body,
- the cutting edge is composed of at least two parts of the rotation center side blade part and the outer peripheral side blade part connected to the radial outer end of the rotation center side blade part, and the tip angle of each blade part is the outer periphery from the rotation center side blade part.
- a small-diameter portion having an outer diameter smaller than the drill diameter is provided on the distal end side of the body to form a cutting blade with the tip angle changed in the small-diameter portion, and the small-diameter portion and the original outer diameter behind the small-diameter portion (
- a Sarae blade having an inclination angle ⁇ with respect to a line perpendicular to the axis of 30 ° or less was provided in a step portion formed between the portion having a drill diameter).
- Such a drill for processing FRP and metal stacks has a radial step in the Sarae blade installation portion obtained by the formula ⁇ (Dd) / D ⁇ where D is the diameter of the drill and d is the diameter of the small diameter portion. It is preferable that the size is set to about 0.06 to 0.13 (the step size per radius is 1/2 of that) by the ratio with the drill diameter.
- the inclination angle ⁇ of the Sarae blade was also tested at 45 ° and 60 °, but 30 ° or less, particularly 15 ° or less, was particularly preferred because the quality of the processed hole was particularly excellent.
- the inclination angle ⁇ of the Sarae blade may be a negative angle.
- a Sarae blade with a negative inclination angle has a sharp outer edge in the radial direction and is liable to be damaged. It's better to make a corner.
- the torsion angle (main torsion angle) of the main part of the torsion groove formed in the drill is set to 5 to 45 °, more preferably 15 to 45 °, and the torsion angle on the tip side of the drill is changed. It is also effective to make it smaller than the main helix angle.
- the twist angle of the twist groove may be changed in the small diameter portion. If the twist angle ⁇ 1 of the small-diameter portion and the main twist angle ⁇ 2 behind the small-diameter portion are both made constant, the drill can be processed easily. However, as the twist angle ⁇ 1 itself of the small-diameter portion goes backward from the tip side of the drill, The size can be increased stepwise or gradually. In this structure, it is preferable that the twist angle ⁇ 1 is smaller than the main twist angle ⁇ 2 by about 5 ° to 10 °.
- a return portion is provided in a part of the twisted groove forming the Sarae blade, and the return angle of the twisted groove in the return portion is made 5 ° to 10 ° smaller than the main twist angle of the twisted groove, or the return portion It is also preferable to set the drill axial width of 0.04D to 0.07D.
- a Sarae blade having an inclination angle ⁇ of 30 ° or less is provided in a step portion between a tip small diameter portion and a portion having an original outer diameter, and the Sarae blade is formed on a metal such as aluminum.
- the outer diameter side of the hole to be processed is processed.
- the cutting edge provided on the tip side small diameter part gradually decreases the tip angle from the center of rotation to the blade part on the outer peripheral side, so the outer diameter of the hole processed into FRP by the cutting edge of the small diameter part The side is machined with a small thrust load. After that, the Sarae blade of the stepped part performs the hole expanding process.
- the installation width (step size) of the Sarae blade is set appropriately.
- the installation width in the drill diameter ratio is preferably in the range of 0.06 to 0.13), so that the quality of the hole processed into the FRP is avoided and the hole processed into the FRP is high quality. Can be secured.
- Sectional drawing which shows the drilling condition by the drill of this invention of the laminated board which made the metal layer down
- channel of the Sarae blade installation part of the drill of this invention Explanatory drawing of the return angle of the return process part given to the twist groove of the Sarae blade installation part of the drill of this invention (arrow X direction view of FIG. 8)
- FIGS. 1 to 9 of the accompanying drawings show an application example to a solid drill.
- the illustrated drill is made of a cemented carbide or the like, and has two cutting edges 3 and 3 having a symmetrical shape at the tip of the body 1 extending from the tip of the shank 2, and a center for reducing the core thickness. It has symmetrical thinning portions 4 and 4, and further has two twisted grooves 5 and 5 on the outer periphery of the body 1.
- the body 1 is provided with a small diameter portion 6 on the distal end side, and a cutting edge 3 is formed on the small diameter portion 6.
- the cutting edge 3 of the exemplary drill includes a rotation center side blade portion 3a, an intermediate blade portion 3b connected to the radially outer end of the rotation center side blade portion, and the intermediate blade portion 3b. It is comprised by 3 parts of the outer peripheral side blade part 3c continuing to a radial direction outer end.
- the tip angle of each blade portion is gradually reduced from the rotation center side blade portion to the outer peripheral side blade portion, and is a so-called three-angle type drill.
- the part located behind the small diameter part 6 of the body 1 is called a large diameter part here.
- the large diameter portion 7 has an original diameter, and a radial step is formed between the large diameter portion 7 and the small diameter portion 6.
- the Sarae blade 8 is provided at the step portion, which is the feature of the invention.
- the diameter of the large-diameter portion 7 of the body is D and the diameter of the small-diameter portion 6 is d.
- the diameter difference between the large-diameter portion and the small-diameter portion, that is, the Sarae blade installation portion obtained by the formula ⁇ (D ⁇ d) / D ⁇ .
- the radial step size (2S) is set in the range of 0.06 to 0.13 as a ratio to the drill diameter.
- the reason for selecting the ratio range is as follows. That is, if the Sarae region by the Sarae blade 8 is too narrow, as shown in FIG. 9, in the drilling of the stacked plate 20 with the metal layer 21 down, a situation occurs in which the metal layer 21 is crushed without being cut. A cylindrical burr is generated at the hole outlet.
- the ratio of the radial step size to the drill diameter to be 0.06 or more, the cutting of the metal layer 21 by the Sarah blade 8 is stably performed, the crushing phenomenon is alleviated, and a clean hole is formed.
- the hole expanding area by the Sarae blade 8 of the pilot hole pre-worked on the FRP 22 by the cutting edge 3 falls within an appropriate range, and the FRP 22 is good. It is avoided that the pilot hole machined into a rough hole is roughened by the hole expansion by the Sarae blade 8.
- the inclination angle ⁇ of the Sarae blade 8 (inclination angle with respect to a line perpendicular to the axis of the drill, see FIG. 4) is set to 0 ° or more and 30 ° or less. By setting the inclination angle ⁇ to 30 ° or less, it is possible to reduce cylindrical burrs generated at the processing hole outlet in the hole processing with the metal layer down.
- the inclination angle ⁇ was particularly preferably 15 ° or less.
- the inclination angle ⁇ may be a negative angle, but at the negative angle, the radial outer end of the Sarah blade 8 becomes too sharp, causing a problem in strength. For this reason, the lower limit was set to 0 ° or more.
- a connecting portion 9 having a fine back taper of about 0.8 to 2.0 / 100 is provided between the radially outer end of the cutting edge 3 and the starting end of the Sarae blade 8.
- the connecting portion 9 is not an essential element, but if this is present, the Sarae blade 8 bites into the work material after the processing by the cutting edge 3 is completely completed. The removal of burrs generated in the layer is made more stable.
- the tip angle ⁇ 1 of the rotation center side blade portion 3a shown in FIG. 4 is 130 °
- the tip angle ⁇ 2 of the intermediate blade portion 3b is 70 °
- the tip angle ⁇ 3 of the outer peripheral side blade portion 3c is 35 °.
- the tip angle is not limited to the exemplified numerical values.
- the tip angle ⁇ 1 of the rotation center side blade portion 3a is about 120 ° to 135 °
- the tip angle ⁇ 2 of the intermediate blade portion 3b is about 70 ° to 100 °
- the tip angle ⁇ 3 of the outer peripheral side blade portion 3c is 55 ° to 10 °.
- Appropriate numerical values can be selected from the range of degrees.
- the application object of the present invention may be a two-angle type drill in which two kinds of tip angles are combined or a drill in which three or more different tip angles are combined.
- the thinning portion 4 is preferably overlap thinning as shown in FIG. 3 (a structure in which the thinning groove enters the flank side beyond the center of the drill) because the reduction effect of thrust is high, but is not limited to this. Absent.
- the twist groove 5 has a twist angle of about 5 ° to 45 °.
- the twist angle is not particularly limited, but it is desirable that the cutting edge of the cutting edge be sharp in FRP processing, so that the twist angle is preferably large, and 15 ° to 45 ° is appropriate.
- the torsion angle ⁇ of the torsion groove 5 may be constant as shown in FIG. 6, but as shown in FIGS. 7 and 8, the torsion angle ⁇ 1 in the small-diameter portion 6 on the distal end side is excluded from the small-diameter portion. It is preferable to make it smaller than the torsion angle (main torsion angle ⁇ 2) of the portion, and this structure can provide the following effects. As described above, the twist angle can be changed in the middle of the length of the twist groove 5 by shaving a part of the groove surface of the twist groove 5.
- the twist angle in the small-diameter portion 6 when the twist angle in the small-diameter portion 6 is reduced, it is preferable to reduce the twist angle ⁇ 1 in the small-diameter portion 6 by about 5 ° to 10 ° with respect to the main twist angle ⁇ 2.
- the effect which changed the twist angle can fully be acquired by making the difference into 5 degrees or more.
- by setting the difference to 10 ° or less it is possible to avoid that the thickness (back metal amount) of the cutting edge forming portion becomes too small and the strength is lowered.
- the torsion angle ⁇ 1 at the distal end side small diameter portion 6 is not necessarily constant.
- a setting that gradually increases or gradually increases from the drill tip side toward the rear side is also conceivable.
- margins 10 are respectively provided at the front edges of the two land portions 12 in the drill rotation direction.
- a diamond coating 11 (see FIG. 5) is provided on the surface of the body 1.
- the drill having the diamond coating 11 is excellent in life, but the cutting edge tends to be rounded due to the influence of the coating.
- the diamond coating 11 increases the coefficient of friction with the work material. For this reason, the generation of burrs at the hole exit of the metal layer of the laminated plate and the metal welding to the drill become more prominent than the drill without the coating.
- the drill of this invention is provided with a Sarae blade suitable for metal processing, even if a diamond coating is provided, burrs and metal welding are unlikely to occur.
- the present invention can also be applied to a blade tip type drill. If a detachable cutting head is mounted on the front end side of the body, and the cutting blade 3 and the Sarah blade 8 are provided on the cutting head, a blade tip type drill can be obtained.
- the blade tip replaceable drill has a smaller number of regrinds to regenerate the blade tip than the solid drill, but has the advantage that the damaged cutting edge can be easily and quickly regenerated by replacing only the cutting head.
- the problem of the present invention that is, the problem of the occurrence of burrs at the hole exit of the metal layer of the laminated plate is particularly remarkable in the CFRP laminated plate, but the FRP contained in the work material is GFRP (glass fiber reinforced plastics). ) And the like, the present invention is also effective in processing a GFRP laminate.
- ⁇ Comparative product 1 No Sarae blade. Other specifications are the same as invented product 1.
- the comparative product 1 had a large cylindrical burr at the exit of the processed hole formed in the aluminum plate.
- the comparative product 2 was not as large as the comparative product 1, the cylindrical burr
- Example 2 Using the same sample and the same work material as in Example 1, the machining conditions were the same, and a hole was made in the work material with the CFRP plate down. As a result, the comparative product 1 had noticeable peeling and fluffing at the exit of the processed hole formed in the CFRP plate. Although the comparative product 2 was not as large as the comparative product 1, fuzz occurred at the exit of the processed hole formed in the CFRP plate.
- a torsion angle of the torsion groove is set to 25 ° only at the small diameter portion, and a drill having the same specifications as that of Invention 1 is made as a trial product. Using the drill, the same work material is used under the same processing conditions as in Example 1. I made a hole. As a result, a back counter (return) at the CFRP outlet did not occur. This is thought to be due to the fact that the chip pockets near the cutting edge have increased the chip discharge performance.
- the twisting process was performed on the twisting groove (the portion that becomes the rake face of the Sarae blade) of the Sarae blade installation part.
- the axial return width W of the return portion (see FIG. 11; the axial width of the return portion 5a) was 0.04D, and the twist angle (main twist angle) and return angle ⁇ (see FIG. 12) of the twist groove were changed. Except for the points, holes were made in the same workpiece under the same processing conditions as in Example 1.
- Tables 1 and 2 show the results of performance evaluation of drills having the main twist angles of 45 ° and 40 ° of the twisted groove in which the angle return is performed on the twisted groove of the Sarae blade forming portion.
- Example 5 return processing was performed on the twist groove (portion that becomes the rake face of the Sarae blade) of the Sarae blade installation part. Except for the point that the return angle ⁇ (see FIG. 12) of the return part is set to 35 ° and the twist angle of the twist groove and the axial return width W (see FIG. 11) of the return part are changed, the same as in Example 1. And drilled holes in the same workpiece under the same processing conditions. As a result, when the return width W in the axial direction of the return portion is set in the range of 0.04D to 0.07D, the occurrence of burrs and delamination can be suppressed, and the strength of the cutting edge and the quality of the machined surface are improved. I was able to.
- Tables 3 and 4 show the results of performance evaluation of drills with main twist angles of 45 ° and 40 ° of the twist groove in this test.
