Description

  The present invention relates to a method for manufacturing a tire molding die, and more particularly to a method for manufacturing a tire molding die for molding a tire having a pattern formed on a tire surface.

  Some conventional tires have a pattern formed on the surface of the tire, for example, a sidewall, as shown in Patent Documents 1 to 3, for example. This pattern is formed not only on the sidewall portion, but also on, for example, a tread portion composed of a land portion and a groove portion, a tire bead portion, and the like.

  In order to form a pattern on these tire surfaces, a transfer pattern for transferring the pattern onto the tire surface is formed in a tire surface region corresponding to the tire surface of a tire molding die for molding the tire. This transfer pattern is usually formed by a processing machine equipped with a turning tool. That is, it is performed by processing the tire surface region of the tire molding die with a turning tool.

Japanese Patent Laid-Open No. 9-11713 JP-A-9-48217 Japanese Patent Laid-Open No. 11-32242

  By the way, the transfer pattern corresponding to the pattern on the tire surface as shown in Patent Documents 1 to 3 can be formed by repeating simple processing. That is, the formation of complicated transfer patterns has not been disclosed so far.

  Therefore, the present invention has been made in view of the above, and an object of the present invention is to provide a method for manufacturing a tire molding die capable of forming a special transfer pattern.

  In order to solve the above-described problems and achieve the object, in the method of manufacturing a tire molding die, a transfer pattern is formed on a tire surface region corresponding to the tire surface of the tire molding die by a turning tool. The turning direction of the turning tool with respect to the tire surface region is inclined with respect to the tire surface region, and the turning tool has a posture when the tire surface region is machined so that the bottom surface of the turning tool is parallel to the processing direction. The turning tool forms an inclined surface in which the amount of dents from the tire surface region increases in the processing direction by one processing on the tire surface region, and the formed inclined surfaces are adjacent to each other. Processing with the turning tool is repeatedly performed so as to overlap at least one of the plurality of inclined surfaces.

  According to the present invention, an inclined surface in which the amount of dents from the tire surface region increases in the processing direction is formed by one-time processing on the tire surface region by the turning tool, and the formed inclined surfaces are adjacent to each other. By repeating processing with this turning tool so as to overlap at least one of the plurality of inclined surfaces, a special transfer pattern, that is, a scale-like transfer pattern that is recessed from the tire surface region, is formed on the tire surface region of the tire molding die. Can be formed. Therefore, when a tire is vulcanized with a mold for molding a tire in which the scale-like transfer pattern is formed on the tire surface region, a scale-like pattern protruding on the tire surface of the vulcanized tire can be formed.

  In the method for manufacturing a tire molding die, the turning tool may be arranged in at least one of the machining direction or a direction orthogonal to the machining direction among a plurality of inclined surfaces adjacent to each inclined surface. It is preferable to repeat the processing on the tire surface region so as to overlap with adjacent inclined surfaces.

  In the method for manufacturing a tire molding die, the turning tool is configured such that the inclined surfaces are shifted in a direction perpendicular to the processing direction with respect to the inclined surfaces adjacent to the inclined surfaces in the processing direction. Thus, it is preferable to repeat the processing on the tire surface region.

  In the above method for manufacturing a mold for molding a tire, the processing direction is any of a mold circumferential direction, a mold radial direction, or an inclination direction between the mold circumferential direction and the mold radial direction. It is preferable that the direction is toward either side.

  In the tire molding die manufacturing method, the turning tool has the same diameter as the width of the inclined surface in a direction orthogonal to the processing direction. The manufacturing method of the metal mold | die for tire molding as described in any one.

  In the method for manufacturing a tire molding die, it is preferable that the turning tool repeats processing on the tire surface region so that the maximum dent amount of each inclined surface is at least two kinds.

  In the method for manufacturing a tire molding die, the turning tool performs processing on the tire surface region so that there are at least two types of widths in the direction perpendicular to the processing direction of the inclined surfaces. It is preferable to repeat.

  The method for manufacturing a tire molding die according to the present invention has an effect that a scaly transfer pattern, which is a special transfer pattern for forming a scaly pattern on the tire surface of the tire, can be formed in the tire surface region.

  Hereinafter, the present invention will be described in detail with reference to the drawings. The present invention is not limited to the following examples. In addition, constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art or those that are substantially the same. Here, the tire is mounted on a vehicle, but includes not only a tire mounted on a passenger car or the like but also a heavy load tire mounted on a truck, a bus or the like.

  As shown in FIG. 1, the processing machine 1 rotates the end mill 2 which is a turning tool in the direction of arrow A. The processing machine 1 processes the tire surface region 31 corresponding to the tire surface of the tire that is vulcanized and molded by the tire molding die 3 of the tire molding die 3 by the end mill 2.

  The processing machine 1 includes a pedestal 11, an X direction moving unit 12, a Z direction moving unit 13, a Y direction moving unit 14, a B direction rotating unit 15, a chuck 16, and a C direction rotating unit 17. It is comprised with the control apparatus which is not shown in figure. An X-direction moving unit 12 is supported on the pedestal unit 11 so as to be movable in the X direction in FIG. Further, a C-direction rotating portion 17 is supported on the pedestal portion 11 so as to be rotatable in the C direction.

  The X-direction moving part 12 is moved in the X direction in the figure with respect to the pedestal part 11 by a motor (not shown). A Z-direction moving portion 13 is supported by the X-direction moving portion 12 so as to be movable in the Z direction in FIG.

A Y-direction moving portion 14 is supported by the Z-direction moving portion 13 so as to be movable in the Y direction in the figure. The motor 13a is rotationally driven by a control device (not shown).

  The Y-direction moving unit 14 is moved in the Y direction in the figure with respect to the Z-direction moving unit 13 by the motor 14a. A B-direction rotating portion 15 is supported on the Y-direction moving portion 14 so as to be rotatable in the B direction in FIG. The motor 14a is rotationally driven by a control device (not shown).

  The B-direction rotating unit 15 is rotated in the B direction in the figure with respect to the Y-direction moving unit 14 by the motor 15a. A chuck 16 is supported by the B-direction moving unit 15 so as to be rotatable in the direction A in FIG. The motor 15a is rotationally controlled by a control device (not shown).

  The chuck 16 is rotated in the direction A by the motor 16a with respect to the B-direction rotating unit 15. The end mill 2 is held at the tip of the chuck 16. The motor 16a is rotationally driven by a control device (not shown).

  The C-direction rotating unit 17 is rotated in the C direction in the figure with respect to the pedestal unit 11 by a motor (not shown). The C-direction rotating unit 17 supports a workpiece, here a tire molding die. The motor (not shown) is rotationally controlled by a control device (not shown).

  As described above, the processing machine 1 can move and rotate the end mill 2 in the X direction, the Y direction, the Z direction, and the B direction with respect to the pedestal 11, and rotate the tire molding die 3 in the C direction. can do. That is, the processing machine 1 can control the end mill 2 with five axes with respect to the tire molding die 3. The 5-axis control of the end mill 2 with respect to the tire molding die 3 is performed by the control device (not shown).

  The end mill 2 is a turning tool, and cuts the tire molding die 3 which is an object to be processed by turning. The end mill 2 has a cylindrical shape with a diameter d, and a horizontal blade 21 is formed on the outer peripheral surface thereof, and a bottom blade 22 is formed on the bottom surface thereof (see FIGS. 2-1 and 2-2). Accordingly, when the outer peripheral surface of the end mill 2 comes into contact with the tire molding die 3, the horizontal blade 21 cuts the tire molding die 3, and when the bottom surface of the end mill 2 comes into contact with the tire molding die 3, the bottom blade 22 The tire molding die 3 is cut. In this embodiment, the end mill 2 has a right angle α between the side blade 21 and the bottom blade 22 (see FIG. 2-2).

  Next, the manufacturing method of the tire molding die according to the present invention, particularly the processing of the tire surface region 31 of the tire molding die 3 by the end mill 2 using the processing machine 1 will be described. First, the processing machine 1 arrange | positions the end mill 2 in the position facing the tire surface area | region 31 of the metal mold | die 3 for tire shaping | molding, as shown to FIGS. 2-1 and 2-2. At this time, the processing machine 1 maintains the attitude of the end mill 2 with respect to the tire surface region 31 so that the bottom blade 22 that is the bottom surface is parallel to the processing direction described later. That is, in the end mill 2, when processing the tire surface region 31, the bottom blade 22, which is a bottom surface with respect to the tire surface region 31, is parallel to the processing direction described later.

  Next, as shown in FIGS. 3A and 3B, the processing machine 1 moves the end mill 2 in the processing direction while maintaining the posture with respect to the tire surface region 31. The tire surface region 31 is processed by bringing them closer and in contact with each other. Here, the processing machine 1 sets the processing direction when processing the tire surface region 31 to the mold circumferential direction and is inclined with respect to the tire surface region 31. Then, the processing machine 1 moves the end mill 2 by a predetermined distance in the processing direction, and then moves the end mill 2 in the separation direction, thereby completing one processing of the tire surface region 31 by the end mill 2. Note that the separation direction is a direction orthogonal to a rotation surface (not shown) of the end mill 2, that is, an axial direction of the end mill 2.

  Accordingly, in the tire surface region 31, as shown in FIGS. 4A and 4B, the amount of dents from the tire surface region 31 can be reduced by one processing on the tire surface region 31 by the end mill 2 that is a turning tool. An inclined surface 32 is formed in which increases in the processing direction. The inclined surface 32 has a U shape that opens in the circumferential direction of the mold, and becomes a semicircular shape as it goes in the processing direction. A direction w perpendicular to the machining direction of the inclined surface 32, that is, a width w in the mold radial direction is the same as the diameter d of the end mill 2. That is, the processing machine 1 only needs to move the end mill 2 once in the processing direction in order to process one inclined surface 32 in the tire surface region 31. Thereby, the scale-like transfer pattern comprised from the several inclined surface 32 mentioned later can be formed in the tire surface area | region 31 of the metal mold | die 3 for tire shaping | molding in a short time.

  Here, as described above, the end mill 2 having the same diameter d as the width w in the mold radial direction of the inclined surface 32 formed in the tire surface region 31 can be used. The end mill 2 having a large diameter d can be used as compared with the case where serration processing, which is a simple transfer pattern, is performed by the end mill 2. Accordingly, in the serration processing, the moving speed in the processing direction of the end mill 2 is lowered from the strength of the end mill 2, but in the processing for forming a scale-like transfer pattern to be described later on the tire surface region 31, it is compared with the serration processing. Since the end mill 2 having high strength can be used, the moving speed of the end mill 2 in the processing direction can be increased, and the processing speed can be improved as compared with the serration processing.

  Moreover, in the process which forms the scale-shaped transfer pattern mentioned later in the tire surface area | region 31, the inclined surface 32 which comprises this scale-shaped transfer pattern can be formed only by moving the end mill 2 to one direction which is a process direction. it can. Therefore, in the process of forming a scale-like transfer pattern to be described later on the tire surface region 31, like the serration process, the end mill 2 is once moved in the direction perpendicular to the tire surface region 31 and then moved in the processing direction. There is no need. Thereby, the moving speed of the end mill 2 in the processing direction can be increased, and the processing speed can be improved as compared with the serration processing.

  In addition, it is preferable that the largest dent amount h of the inclined surface 32 is 0.1 mm or more and 10 mm or less. Furthermore, it is preferable that it is 0.3 mm or more and 5 mm or less. Here, the reason why the maximum protrusion amount H is 0.1 mm or more is that it is difficult to form the inclined surface 32 if it is less than 0.1 mm. Further, the maximum dent amount H is set to 10 mm or less. When the maximum dent amount H exceeds 10 mm, the weight of a tire (not shown) vulcanized and molded by the tire molding die 3 increases, and the scale-like shape formed in the tire surface region 31 is increased. This is because cracks may occur between the scale-like pattern formed on the tire surface (not shown) by the transfer pattern and the tire surface (not shown).

  Moreover, it is preferable that the width | variety w of the die radial direction of the inclined surface 32 is 0.2 mm or more and 20 mm or less. Furthermore, it is preferable that it is 2 mm or more and 5 mm or less. Here, when the width w is 0.2 mm or more, the diameter d of the end mill 2 is also 0.2 mm when the width w is less than 0.2 mm, the durability and strength of the end mill 2 are reduced, and the tire surface region 32 is reduced. This is because processing by the end mill 2 becomes difficult. The width w of 20 mm or less is not necessary for the scale-like pattern formed on the tire surface (not shown) due to the scale-like transfer pattern formed on the tire surface region 31 when the width exceeds 20 mm. It is because there is a possibility that unevenness is conspicuous.

  Next, as shown in FIGS. 4A and 4B, the processing machine 1 is adjacent to the inclined surface 32 already formed in the tire surface region 31 and the direction orthogonal to the processing direction, that is, the mold radial direction. The end mill 2 is moved to a position where the inclined surface 32 can be formed. Then, the processing machine 1 moves the end mill 2 in the processing direction, and processes the portion of the tire surface region 31 adjacent to the already formed inclined surface 32 in the mold radial direction by the end mill 2, and the already formed inclined surface. An inclined surface 32 is formed adjacent to 32 in the mold radial direction.

  Next, as shown in FIGS. 5A and 5B, the processing machine 1 repeats the processing of the tire surface region 31 by the end mill 2 so that the inclined surface is adjacent to the tire surface region 31 in the mold radial direction. 32 are formed for one line.

  Next, as shown in the figure, the processing machine 1 moves the end mill 2 to a position shifted in the mold radial direction from the inclined surface 32 formed in a line in the mold radial direction. Then, the processing machine 1 moves the end mill 2 in the processing direction, and as shown in FIGS. 6A and 6B, the inclined surface 32 in which the tire surface region 31 is already formed overlaps in the processing direction (same as above). From the range surrounded by the dotted line and the solid line) to the portion adjacent to the inclined surface 32 in the mold circumferential direction is processed by the end mill 2 to form the inclined surface 32 that overlaps the already formed inclined surface 32 in the processing direction. To do.

  Here, when forming the inclined surface 32 that overlaps in the processing direction with the inclined surface 32 in which the tire surface region 31 has already been formed, the inclined surface is closer to the processing direction than the inclined surface 32 in which the tire surface region 31 has already been formed. It is preferable to form an inclined surface 32 that overlaps 32 in the processing direction. This is because when forming the inclined surface 32 that overlaps in the processing direction, the tire surface region 33 processed by the side blade 21 of the end mill 2 when forming the inclined surface 32 in which the tire surface region 31 has already been formed, particularly the edge. This is because the bottom blade 22 of the end mill 2 is processed again when forming the inclined surface 32 that overlaps the portion (dotted line in the figure) in the processing direction. Therefore, the burr | flash etc. which generate | occur | produce when the end mill 2 processes the tire surface area | region 31 can be suppressed. Thereby, the deburring and grinding | polishing by the manual work performed after the process of the tire surface area | region 31 of the end mill 2 can be reduced.

  Next, as described above, the processing machine 1 can already form the inclined surface 32 so as to be adjacent to the inclined surface 32 formed in the tire surface region 31 and the direction orthogonal to the processing direction, that is, the mold radial direction. The end mill 2 is moved to the position. Then, the processing machine 1 moves the end mill 2 in the processing direction, and processes the portion of the tire surface region 31 adjacent to the already formed inclined surface 32 in the mold radial direction by the end mill 2, and the already formed inclined surface. An inclined surface 32 is formed adjacent to 32 in the mold radial direction.

  Next, as shown in FIG. 7, the processing machine 1 repeats the processing of the tire surface region 31 by the end mill 2, so that the processing surface side of the inclined surface 32 adjacent to the tire surface region 31 in the mold radial direction is The inclined surfaces 32 adjacent to each other in the mold radial direction are formed in which the inclined surfaces 32 in the processing direction are shifted in the mold radial direction.

  And the processing machine 1 repeats the operation | movement mentioned above, and as shown to FIGS. 8-1 and FIGS. 8-2, by processing the tire surface area | region 31 with the end mill 2, each inclined surface 32 is in a process direction. A plurality of inclined surfaces 32 that overlap with a plurality of adjacent inclined surfaces 32 are formed in the tire surface region 31. As described above, by the method for manufacturing a tire molding die according to the present invention, the amount of dents from the tire surface region 31 toward the tire surface region 31 of the tire molding die 3 is directed in the processing direction as shown in FIG. The scale-like transfer pattern 33 is formed as a special transfer pattern in which each of the inclined surfaces 32 that increase in number overlaps with the plurality of adjacent inclined surfaces 32 in the processing direction. Therefore, when a tire is vulcanized by the tire molding die 3 having the scale-like transfer pattern formed on the tire surface region 31, a scale-like pattern protruding on the tire surface of the vulcanized tire may be formed. it can.

  In the above embodiment, the end mill 2 having a right angle α between the horizontal blade 21 and the bottom blade 22 is used, but the present invention is not limited to this, and 20 ° ≦ α ≦ 160 ° is preferable. Furthermore, it is preferable that 60 ° ≦ α ≦ 135 °. 10-1 to 10-3 are diagrams for explaining processing of the tire surface area with other turning tools. For example, as shown in FIGS. 10A to 10C, an end mill 2 having an acute angle (α <90 °) between the inclined blade (horizontal blade) 23 and the bottom blade 22 may be used.

  In this case, the processing machine 1 arrange | positions the end mill 2 in the position facing the tire surface area | region 31 of the metal mold | die 3 for tire shaping | molding, as shown to FIGS. 10-1, and the attitude | position with respect to the tire surface area | region 31 of this end mill 2 Is maintained so that the bottom blade 22 which is the bottom surface is parallel to a processing direction which will be described later. Next, as shown in FIG. 10B, the processing machine 1 moves the end mill 2 in the processing direction while maintaining the posture with respect to the tire surface region 31. Then, the processing machine 1 moves the end mill 2 by a predetermined distance in the processing direction, and then moves the end mill 2 in a disengagement direction opposite to the processing direction, so that the tire surface region 31 by the end mill 2 is moved once. Then, the inclined surface 32 is formed in the tire surface region 31. As a result, a recess 34 is formed in the tire surface region 31 so as to enter the circumferential direction of the mold, and the inclined surface 32 can be formed by partially entering the inside of the tire surface region 31 in the mold circumferential direction. . Therefore, the tire is added by the tire molding die 3 in which a scaly transfer pattern formed by a plurality of inclined surfaces 32 partially entering the tire surface region 31 in the tire circumferential direction is formed in the tire surface region 31. When the vulcanization molding is performed, the scale-like pattern formed on the tire surface of the vulcanized tire is constituted by a plurality of inclined surfaces having sharp edges at the ends in the tire circumferential direction.

  Moreover, in the said Example, although the several inclined surface 32 which comprises the scale-like transfer pattern 33 adjoins the inclined surface 32 adjacent in a process direction among several inclined surfaces 32, this invention is limited to this is not. For example, the scale-like transfer pattern 33 may be constituted by a plurality of inclined surfaces 32 in which adjacent inclined surfaces 32 overlap in a direction orthogonal to the processing direction among the plurality of adjacent inclined surfaces 32.

  Moreover, in the said Example, although the processing direction of the end mill 2 which is a turning tool is made into the direction which goes to a metal mold | die circumferential direction, this invention is not limited to this. For example, the machining direction of the end mill 2 that is a turning tool may be a mold circumferential direction or an inclination direction between the mold circumferential direction and the mold radial direction. In this case, the end mill 2 forms an inclined surface in the plurality of tire surface regions 31 in which the amount of dents from the tire surface region increases toward the mold circumferential direction or the mold radial direction by repeated processing on the tire surface region. It becomes.

  Moreover, in the said Example, although each inclined surface 32 which comprises the scale-shaped transcription | transfer pattern 33 is formed so that the maximum dent amount h may become the same, this invention is not limited to this. For example, you may form so that the maximum dent amount h may differ for every row of inclined surface 32 adjacent to a metal mold | die radial direction. That is, the end mill 2 may repeat the processing on the tire surface region 31 so that the maximum dent amount h of each inclined surface 32 is at least two kinds.

  Moreover, in the said Example, although each inclined surface 32 which comprises the scale-shaped transcription | transfer pattern 33 is formed so that the maximum dent amount h may become the same, this invention is not limited to this. For example, each row of inclined surfaces 32 adjacent to each other in the mold radial direction may be formed so that the width in the direction orthogonal to the processing direction, here, the width w in the mold radial direction is different. That is, the end mill 2 may repeat the processing on the tire surface region 31 such that the width w of each inclined surface 32 is at least two or more.

  As described above, the method for manufacturing a tire molding die according to the present invention is suitable for forming a special transfer pattern.
