Description

  The present invention relates to an edge processing tool, an edge processing apparatus, and an edge processing method, and more specifically, in an edge processing of a workpiece such as steel, a single processing from one side of the workpiece. Thus, the present invention relates to an edge processing tool, an edge processing apparatus, and an edge processing method capable of simultaneously performing edge processing on both edge portions on the front surface side and the back surface side of the workpiece.

  Usually, as the edge treatment (edge treatment) of the steel material, in the cross section perpendicular to the direction along the edge of the steel material, as shown in FIG. And a rounding process called “R process” in which rounding is formed at the edge a1 as shown in FIG.

  On the other hand, in the shipbuilding world, due to frequent ship accidents worldwide, social momentum seeking respect for human life and environmental conservation is increasing. For this reason, regulations are being strengthened by the International Maritime Organization (IMO) and the International Federation of Classification Societies (IACS). With this rule strengthening, steel materials used for ballast tanks that use seawater as ballast in the Protective Coating Performance Standard (PSPC), Common Structure Rules (CSR), etc., have sharp edges e as shown in FIG. Removal is required, and in a cross section perpendicular to the direction along the end surface S3, the notch width b and height h of the edge portion 1a as shown in FIG. 13 are about 0.5 mm to 1.0 mm. R processing (2R processing) that forms a circular roundness with a radius r of about 2 mm as shown in FIG. 14 or 3-pass G processing that is not shown in the drawing but is applied three times (not shown), such as processing (1C processing). Is required.

  In order to satisfy the requirements for the edge processing, it is necessary to change the edge processing in which the C processing is performed from both sides of the steel material using the conventional rotary bar or the disk sander to the R processing. The problem that the man-hour required for the edge processing of steel materials increases arises, and it becomes an important subject to reduce this man-hour which increases.

  As an edge processing device used for performing this R processing, a cutter tip having a quarter arc of a cutting edge shape (a shape in a cross section including a rotating shaft) provided around the disk is provided. There is. In this edge processing apparatus, the edge processing apparatus is pressed against the end of the steel material and moved along the end of the steel material so that the arc-shaped cutter tip part contacts the end edge of the steel material. R processing can be performed by cutting the edge portion on the surface side of the workpiece.

  As such an edge processing apparatus, for example, while rotating a cutter attached with a cutter tip having an arcuate cutting blade, as a guide for this cutter tip, a rotary base on the outer peripheral side of the cutter, and a lower end side of the cutter A guide roller is provided on the plate surface of the workpiece, and the guide roller is brought into contact with the end surface as a guide, and the cutting edge of the cutter tip rotating with the cutter is applied. There has been proposed a chamfering machine that cuts corner portions (edge portions) of a workpiece and performs R treatment by moving in contact (see, for example, Patent Document 1).

  In addition, the first guide member provided on the frame of the edge processing apparatus is brought into contact with the plane of the workpiece (workpiece), and the rotary cutting blade is rotated as a guide by contacting a guide roller having the same rotation axis to the end surface. An edge processing apparatus that performs edge processing of a workpiece with a cutting blade has been proposed (see, for example, Patent Document 2 and Patent Document 3).

  However, in any apparatus, since the edge processing on the surface side can only be performed from one side of the steel material, the edge processing on both sides is performed two times on both sides. There is a problem that is necessary.

JP-A-8-57707 JP-A-8-66812 JP 2009-142946 A

  The present invention has been made in view of the above-described situation, and the object of the present invention is to perform a single edge treatment from one side of the workpiece in the edge treatment of the steel, and the surface side of the workpiece. An object of the present invention is to provide an edge processing tool, an edge processing apparatus, and an edge processing method capable of simultaneously performing edge processing on both edge portions on the back surface side.

  In order to achieve the above object, the edge processing tool of the present invention is configured to rotate the edge processing tool and move the edge processing tool along the end of the workpiece, thereby moving the workpiece. In an edge processing tool for attaching an edge portion of a material to an edge processing apparatus that performs edge processing by machining by rotation of the edge processing tool, the processing portion of the edge processing tool is arranged on the surface side of the workpiece. A first processing portion that contacts the edge portion of the workpiece and a second processing portion that contacts the edge portion on the back surface side of the workpiece, and the edge portion on the surface side of the workpiece. The first processed portion is formed so that the second processed portion is simultaneously brought into contact with an edge portion on the back surface side of the workpiece, and the edge portions on both the front surface side and the back surface side are simultaneously edge processed. Is done.

  This end face processing tool is a tool for machining to remove a part of a work piece such as a metal steel plate, and a grinding tool that cuts the surface with a grindstone or the like, and a tool that is pressed to remove the surface. Cutting tools.

  According to this configuration, the first processed portion is simultaneously brought into contact with the edge portion on the surface side of the workpiece such as steel, and the second processed portion is simultaneously brought into contact with the edge portion on the back surface side of the workpiece, Since both edge portions on the back side are formed to be edge-treated at the same time, in edge processing, it is only necessary to move once along the edge of the workpiece from one side of the workpiece. The edge portions on both the front surface side and the back surface side of the edge portion of the workpiece can be edge processed by machining by grinding or cutting, and the man-hour required for the edge processing can be reduced. In addition, when the first processing portion and the second processing portion are in contact with the workpiece, the portion between the first processing portion and the second processing portion is not in contact with the end portion of the workpiece. In addition, a recess is provided in the portion between them.

  In the above edge processing tool, when at least one of the first processing portion and the second processing portion is formed so that the machined surface of the workpiece has a curved shape, the edge processing of the rounding process is performed. It is possible to perform this, and even when R processing is requested, it is possible to sufficiently cope.

  In the above edge machining tool, the first machining portion and the second machining portion are formed separately, and the separation distance in the rotation axis direction between the first machining portion and the second machining portion can be changed. When configured, it is easy to perform edge processing so that the same cross-sectional shape is obtained in the rounding process regardless of the plate thickness of the workpiece by changing the separation distance according to the plate thickness of the workpiece. become able to.

  This separation distance can be easily performed by separating the first processed portion and the second processed portion so that the spacer is formed corresponding to the plate thickness of the workpiece, and sandwiching between the processed portions. Can do. Alternatively, the second processing portion is configured to be movable in the direction of the rotation axis by, for example, screwing the second processing portion with respect to the first processing portion, and manually moved according to the plate thickness of the workpiece, or the plate It can also be easily performed by automatically moving the second processing portion in the direction of the rotation axis with respect to the first processing portion in conjunction with the thickness detection mechanism or the plate thickness detection sensor.

  In the above edge processing tool, the edge processing tool includes a single grindstone member, a plurality of grindstone members, a single rotary cutting member, a plurality of rotary cutting members, or a single or a plurality of cutter tips. Formed with any one of the cutters.

  When the edge processing tool is formed of a single grindstone member, a single rotary cutting member, or a single cutter tip, the edge processing tool is formed in a drum shape whose center is recessed in the rotation axis direction. That is, when these edge processing tools are rotated around the rotation axis, the outermost shape in the side view is formed so that the central portion is recessed. In this case, when the edge processing tool is formed so as to be plane-symmetric with respect to a vertical plane including the center of the rotation axis direction of the edge processing tool, the edge processing on the front side and the back side of the workpiece is performed. It becomes possible to easily make the cross-sectional shape of the end edge portion the same.

  In addition, when the edge processing tool is formed of any one of a plurality of grindstone members, a plurality of rotary cutting members, or a cutter having a single cutter tip, the center of the edge processing tool in the rotation axis direction When the grindstone member and the rotary cutting member are formed so as to be plane-symmetric with respect to the center plane perpendicular to the rotation axis, the cross-sectional shape after the edge processing on the front surface side and the back surface side of the workpiece is obtained. It becomes easy to make the same shape. In addition, when formed with a cutter having a plurality of cutter tips, when the cutter is rotated, the shape cut by the cutter tip is plane-symmetric with respect to the center plane of the edge processing tool. Deploy.

  In addition, the edge processing apparatus for achieving the above object rotates the edge processing tool and moves the edge processing tool in contact with the end portion of the workpiece. It is comprised so that the edge part of both the surface side and the back surface side of the said workpiece may be edge-processed simultaneously.

  According to this configuration, the edge processing tool simultaneously applies the first processing portion to the edge portion on the front surface side of the workpiece such as steel and the second processing portion to the edge portion on the back surface side of the workpiece. In contact with each other, the edge portions on both the front surface side and the back surface side are formed at the same time, so in edge processing, from one side of the workpiece to the edge of the workpiece. The edge processing on both the front surface side and the back surface side of the end portion of the workpiece can be simultaneously edged only by moving once. Therefore, the man-hour required for edge processing can be reduced.

  And the edge processing method for achieving the above-mentioned object is to rotate the above-mentioned edge processing tool and move the edge processing tool in contact with the end portion of the workpiece, In this method, the edge portions of both the front surface and the back surface of the workpiece are subjected to edge treatment at the same time.

  According to this method, since the edge processing is simultaneously performed on both the front surface side and the back surface side with the edge processing tool, in the edge processing, the end portion of the work material from one side of the work material. The edge processing on both the front surface side and the back surface side of the end portion of the workpiece can be performed with a single edge movement. Therefore, the man-hour required for edge processing can be reduced.

  Hereinafter, an edge processing tool, an edge processing apparatus, and an edge processing method according to the present invention will be described with reference to the drawings.

  As shown in FIGS. 1 to 12, the edge processing tools 10A to 10F according to the embodiment of the present invention are edge processing apparatuses that perform edge processing by machining by rotation of the edge processing tools 10A to 10F ( This is an edge processing tool to be attached to an unillustrated). In the edge processing apparatus, the edge processing tools 10A to 10F are driven to rotate and moved along the end S3 of the work material 20 such as a steel material forming a ballast tank of a ship. The edge portions a1 and a2 are processed by machining.

  These edge processing tools 10A to 10F are rotary body grinding tools 10A and 10B such as a grindstone that can cut the surface of the workpiece 20, or cutting that presses against the workpiece 20 to remove the surface. It is formed with tools 10C to 10F. The cutting tools 10C to 10F have cutting edges on the outer periphery and end face, and milling cutters 10C and 10D, which are rotary cutting tools that perform cutting in a direction perpendicular to the rotation center axis Cr of the tool, or a cutter tip on a cutter disk. It is formed with the provided cutters 10E and 10F. As shown in FIGS. 1 to 4, when this edge processing tool is formed by a rotating grinding tool 10 </ b> A or 10 </ b> B such as a grindstone, a rotating grindstone is rotated at high speed to grind or polish a material or a tool. The same material as the grinder's grindstone, for example, aluminum oxide, silicon carbide, or extremely hard mineral such as diamond or cBN (cubic boron nitride) is used as abrasive sand, and resin or soft metal is used as a binder. Can be formed.

  As shown in FIGS. 5 to 8, when the edge processing tool is formed by a rotary cutting tool 10 </ b> C or 10 </ b> D such as a milling cutter, the same material as that of a general milling cutter, for example, high-speed steel or carbide It is made of an alloy, and cBN or sintered diamond is used for the cutting edge portion as necessary. And a cutting blade is provided in an outer periphery similarly to a flat milling machine.

  Moreover, as shown in FIGS. 9-12, when forming an edge processing tool with the cutters 10E and 10F provided with the cutter tips 13E and 13F, these cutter tips 13E and 13F are the same as a general cutter tip. For example, cBN or sintered diamond is used for the cutting edge portion as necessary. Then, like the cutter, cutter chips 13E and 13F having cutting edges on the outer circumferences of the cutter disks 14E and 14F are attached and used.

  First, the case where the edge processing tool is formed by the rotary body grinding tools 10A, 10B or the rotary body cutting tools 10C, 10D will be described. However, in order to avoid duplication of description, the rotary body grinding tools 10A, 10B (or The rotating body cutting tools 10C and 10D) will be described. However, in the case of the rotating body grinding tools 10A and 10B, the grinding tool itself is formed by the rotating bodies 11A and 11B. In the case of the rotating body cutting tools 10C and 10D, the outermost shape when rotated is as follows. Although it becomes the rotary bodies 11C and 11D, since the cutting blade is formed when the rotation is stopped, it does not become a rotary body in a strict sense. However, in order to simplify the description, here, it will be described as a “rotary body cutting tool”. Accordingly, the rotating bodies 11C and 11D mean the outermost shapes when they are rotated, even if the rotating body cutting tools 10C and 10D are not refused one by one.

  When the edge processing tool is formed by a single rotary body grinding tool 10A (or a single rotary body cutting tool 10C), the shape is shown in FIGS. 1 and 2 (or FIGS. 5 and 6). As shown in FIG. 4B, the drum is formed in a drum shape in which the center in the direction of the rotation axis Cr is recessed. That is, it is formed by the rotating body 11A (11C) fixed to the shaft 12 having the rotation axis Cr, and is formed in a shape in which the central portion is recessed in the cross-sectional shape including the rotation axis Cr. In other words, the diameter of the rotating body 11A (11C) is gradually decreased from one side to the other side in the direction of the rotation axis Cr to become the minimum diameter portion 11Aa (11Ca), and thereafter the diameter is gradually increased. . In this case, a vertical plane including the center P in the rotation axis direction (height direction) of the rotating body 11A (11C) (so as to be plane-symmetric with respect to the plane Sp perpendicular to the rotation axis Cr, that is, 1 and 2 (or FIG. 5 and FIG. 6), the rotating body 11A (11C) is formed so as to be vertically symmetrical. And the cross-sectional shape after the edge processing on the back surface S2 side can be easily made the same shape.

  Note that the bus bar 11Ab (11Cb) on the side surface of the rotating body 11A (11C) shown in FIG. 2 (or FIG. 6) is formed in accordance with the shape required for the edge processing of the workpiece 20. That is, in the chamfering process for forming the C surface, the bus bar 11Ab (11Cb) has a linear shape, and the rotating body 11A (11C) is a combination of a truncated cone, a cylinder, and an inverted truncated cone, or a truncated cone and an inverted cone. Formed by joining the tables. In the rounding process for forming the R surface, the bus bar 11Ab (11Cb) has a curved shape, a combined shape of curves, or a combined shape of two or more curves and straight lines, and the rotation axis Cr of the rotating body 11A (11C). As shown in FIG. 1 (or FIG. 5), the cross section including the shape has a concave portion on the upper side and the lower side. This recessed part may be formed only with the continuous single or several curve, and may have a linear part in the middle. It is preferable to use an arc or an elliptical arc for this curve because it is easy to design and process, but it is not necessary to be limited to these.

  Further, the height H in the rotation axis direction shown in FIG. 1 (or FIG. 5) is such that the edge processing tool 10A (or 10C) is simultaneously applied to the edge portion a1 on the surface S1 side and the back surface S2 side of the workpiece 20. In order to be able to come into contact with the end edge part a2, it is necessary to form the workpiece 20 larger than the plate thickness T.

  As an example of the dimensions of the rotating body 11A (11C), for example, as shown in FIG. 1 (or FIG. 5), the upper and lower ends have a circular arc shape with a diameter R1 of 30 mmφ and a concave diameter R2 of 20 mmφ. The height H may be 32 mm, or the upper and lower ends may have an arc shape with a diameter R1 of 25 mmφ and a concave diameter R2 of 17 mmφ, and a height H of 50 mm.

  One side of the rotating shaft Cr, that is, the upper portion of the concave portion 11Aa (11Ca) of the recess in FIG. 1 (or FIG. 5) is the first processed portion 11Ac (11Ca), and the other side of the rotating shaft Cr. That is, a lower part than the minimum diameter portion 11Aa (11Ca) of the concave portion in FIG. 1 or FIG. 5 becomes the second processed portion 11Ad (11Cd).

  When the edge processing tool is formed by a plurality of rotating body grinding tools 10B (or a plurality of rotating body cutting tools 10D), it is shown in FIGS. 3 and 4 (or FIGS. 7 and 8). As described above, the rotating body grinding tool 10B (or the rotating body cutting tool 10D) is arranged so as to be plane-symmetric with respect to the vertical plane Sp including the center P in the rotation axis Cr direction of the edge processing tool. The rotary body grinding tools 11Bc and 11Bd (or the rotary body cutting tools 11Dc and 11Dd) arranged on one side and the other side of the rotary shaft Cr are respectively connected to the edge a1 on the surface S1 side of the workpiece 20 and the edge part a1. It arrange | positions in the position which can contact | abut to the edge part a2 by the side of back S2. One side of the rotating body grinding tool 10B (or rotating body cutting tool 10D) arranged symmetrically with respect to the plane, that is, the upper portion of FIGS. 3 and 4 (or FIGS. 7 and 8) is the first processing portion 11Bc ( 11Dc), and the other side, that is, the lower portion of FIGS. 3 and 4 (or FIGS. 7 and 8) is the second processed portion 11Bd (11Dd).

  Next, as shown in FIGS. 9 to 12, the cutter tips 13E and 13F having the cutting blades 13Ea and 13Fa are fitted into the outer peripheral side of the rotating cutter bodies (or milling heads) 14E and 14F in an exchangeable manner, With the cutting edges 13Ea and 13Fa of the cutter chips 13E and 13F called the throw-away chips, the end surface S3 of the workpiece 20 is edge-processed in the same manner as the rotary body cutting tools 10C and 10D. In this case, the edge processing tool is formed by cutters 10E and 10F provided with cutter chips 13E and 13F on cutter disks 14E and 14F.

  And as shown in FIG.9 and FIG.10, when the cutter chip 13E of 1 sheet has the 1st process part 13Ec and the 2nd process part 13Ed, the cutter chip 13E is made into the rotating shaft Cr direction of the cutter body 14E. The center P is formed so as to be vertically symmetric with respect to the center plane Sp perpendicular to the rotation axis Cr. Moreover, it forms in the concave shape where the rotation center P vicinity depresses. In this case, it is necessary to form the cutting blade 13Ea at a portion that contacts at least the upper and lower workpieces 20 of the cutter tip 13E.

  The concave shape of the cutter chip 13E is formed in accordance with the shape required for edge processing of the workpiece 20. That is, in the case of the chamfering process for forming the C surface, the shape is formed by combining straight lines. Or in the case of the rounding process which forms R surface, it is set as the curve shape, the combination shape of a curve, or the combination shape of two or more curves and a straight line. This recessed part may be formed only with the continuous single or several curve, and may have a linear part in the middle. It is preferable to use an arc or an elliptical arc for this curve because it is easy to design and process, but it is not necessary to be limited to these.

  One side of the cutter tip 13E, that is, the upper part of the minimum diameter portion of the concave portion in FIGS. 10 and 11 becomes the first processed portion 13Ec, and the other side of the rotating shaft, that is, the concave portion in FIGS. The lower part than the minimum diameter part is the second processed part 13Ed.

  As shown in FIGS. 11 and 12, when the edge processing tool is formed with a plurality of cutter tips 13F, the cutter tips 13F include the center P in the direction of the rotation axis Cr of the cutter 10F. The center plane Sp perpendicular to the rotation axis Cr is disposed so as to pass through a position that is vertically symmetric when rotated.

  That is, it is not always necessary to arrange the cutter 10F in the rotational direction, and the cutter 10F may be arranged so that it can be cut into a vertically symmetrical shape with respect to the center plane Sp when the cutter 10F rotates.

  The cutter tip 13Fc arranged on one side of the rotating shaft Cr, that is, the upper side of FIGS. 11 and 12 serves as a first processing portion, and on the other side of the rotating shaft Cr, that is, on the lower side of FIGS. The arranged cutter tip 13Fd becomes the second processed portion.

  With the configuration of the edge processing tool described above, the processing portions of the edge processing tools 10A to 10F are contacted with the edge a1 on the surface S1 side of the workpiece 20 and the first processing portions 11Ac to 11Fc and the workpiece 20 can be formed by providing second processed portions 11Ad to 11Ad that are in contact with the end edge portion a2 on the back surface S2 side. At the same time, the first processed portions 11Ac to 11Fc are simultaneously applied to the edge a1 on the surface S1 side of the workpiece 20, and the second processed portions 11Ad to 11Ad are simultaneously applied to the edge a2 on the back surface S2 of the workpiece 20. In contact with each other, the edge portions a1 and a2 on both the front surface S1 side and the back surface S2 side can be subjected to edge processing.

  In the edge processing using the edge processing tools 10A to 10F having this configuration, the edge processing tools 10A to 10F that are rotationally driven are transferred from one side of the workpiece 20 to the end S3 of the workpiece 20. The edge portion a1 and a2 on both the front surface S1 side and the rear surface S2 side of the end portion S3 of the workpiece 20 can be edge-treated only by moving the workpiece 20 along the edge. Can be reduced.

  Further, when at least one of the first processing portions 10Ac to 10Fc and the second processing portions 11Ad to 11Ad of the edge processing tools 10A to 10F is formed so that the cut section of the workpiece 20 has an arc shape. Can perform edge processing of rounding processing, and can cope with the case where R processing is requested.

  Further, in the edge machining tools 10B, 10D, and 10F, the first machining parts 11Bc, 11Dc, and 11Fc and the second machining parts 11Bd, 11Dd, and 11Fd are formed separately, and the separation distance thereof can be changed. If comprised, this rounding process which becomes the same cross-sectional shape can be easily performed by changing this separation distance according to plate | board thickness T of the workpiece 20 irrespective of plate | board thickness T of the workpiece 20 become.

  This separation distance can separate the first processing parts 11Bc, 11Dc, and 11Fc and the second processing parts 11Bd, 11Dd, and 11Fd as shown in FIGS. 3, 4, 7, 8, 11, and 12. And can be easily performed by sandwiching the spacers 11Bs, 11Ds, and 14Fs between the two processed portions in accordance with the plate thickness T of the workpiece 20. In addition, the second processed portions 11Bd, 11Dd, and 11Fd are configured to be movable in the direction of the rotation axis Cr by screwing the second processed portions 11Bd, 11Dd, and 11Fd with the first processed portions 11Bc, 11Dc, and 11Fc. The second processing portions 11Bd, 11Dd, and 11Fd are rotated with respect to the first processing portions 11Bc, 11Dc, and 11Fc manually or in conjunction with the plate thickness detection mechanism or the plate thickness detection sensor. It can also be easily performed by moving in the direction of the axis Cr.

  Next, the edge processing apparatus according to the present invention will be described. The edge processing apparatus rotates the edge processing tools 10A to 10F and moves the edge processing tools 10A to 10F in contact with the end S3 of the workpiece 20, thereby moving the workpiece. The edge portions a1 and a2 on both the front surface S1 side and the back surface S2 side of the material 20 are simultaneously edged.

  This edge processing apparatus can utilize the mechanism of a conventional terminal processing apparatus that performs end surface processing on only one side, and includes a cutter and a rotary cutting blade for machining the edge processing apparatus of this prior art. Instead of the edge processing tools 10A to 10F configured as described above, the edge processing apparatus can be reconfigured. Along with this change, the edge processing tools 10A to 10F have a height H in the direction of the rotation axis Cr and exceed the plate thickness T of the workpiece 20, so that the weight may increase. The increase in the driving force of the electric motor or the air motor that rotates the edge processing tools 10A to 10F can be sufficiently handled. The edge processing apparatus uses an electric motor, an air motor, a hydraulic motor or the like as a rotating device for rotating the edge processing tools 10A to 10F, and uses a power such as an electric tool, a pneumatic tool (air tool), and a hydraulic tool. It can be configured as a tool (power tool) and can be configured as a manual tool (hand tool, work tool).

  According to the edge processing tool having this configuration, the first processing portions 11Ac to 11Fc are provided on the end edge portion a1 on the surface S1 side of the workpiece 20 such as steel, and the edge portion a2 on the back surface S2 side of the workpiece 20 is provided. Since the second processed portions 11Ad to 11Fd are simultaneously brought into contact with each other and the edge portions a1 and a2 on both the front surface S1 side and the back surface S2 side are subjected to edge processing, in the edge processing, The edge part a1, a2 on both the front surface S1 side and the back surface S2 side of the edge part S3 of the workpiece 20 can be moved once along the edge part S3 of the workpiece 20 from one side of the workpiece 20. Can be edge processed simultaneously. Therefore, the man-hour required for edge processing can be reduced.

  In addition, the edge processing method according to the present invention rotationally drives the edge processing tools 10A to 10F having the above-described configuration, and brings the edge processing tools 10A to 10F into contact with the end S3 of the workpiece 20. In this method, the edge portions a1 and a2 of both the front surface S1 and the rear surface S2 of the workpiece 20 are simultaneously edge-treated by moving the workpiece.

  According to this method, the edge processing tools 10A to 10F having the above-described configuration perform edge processing on both the edge portions a1 and a2 on the front surface S1 side and the back surface S2 side at the same time.
