JP 2009-300306 A

  The jumper as described above has a base portion that supports the base of the spring portion, in addition to the spring portion and the jumping claw portion. In general, a jumper used in a mass-produced timepiece is formed by pressing a single metal thin plate a plurality of times in a progressive press machine. However, for example, the formation position of the spring part or the jumping claw part may slightly shift due to some cause such as wear of the mold due to long-term use. However, since it is necessary to accurately control the rotation of the date indicator wheel or the like, the tolerance of the tip position of the jumping claw portion is particularly severe. For this reason, if the formation position of the spring portion or the jumping claw portion is slightly shifted due to some cause, all the jumpers manufactured during this time are handled as defective products in the subsequent inspection process.

  If a jumper with a slightly displaced position of the spring or jumping claw is generated, remove the mold from the press machine, and insert the mold for forming the spring or jumping claw from the mold. Furthermore, it is necessary to remove, scrape the side surface of the insert, return it to the mold while adjusting the position of the insert, and insert a shim into the gap that will be formed by cutting the side surface of the insert. . For this reason, under the present circumstances, if the formation position of the spring part or the jumping claw part is shifted, it takes a long time to correct it.

  Such a problem is not limited to the spring part and the jumping claw part of the jumper. Since watch parts are required to be extremely precise, tight tolerances are set. For this reason, in a timepiece component having a configuration in which a linear spring is connected to the base portion, if the positional deviation of the linear spring occurs, a long time is required for correction, not limited to the jumper.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to make it possible to easily adjust the position of a linear spring in a watch component having a configuration in which a linear spring is connected to a base portion. To do.

  The present invention adopts the following configuration as means for solving the above-described problems.

Even if the distance is shallow, the position of the linear spring can be easily adjusted.

  According to a third aspect of the present invention, in the first or second aspect of the present invention, the posture adjusting recess has a configuration in which the shape in plan view is a rectangular shape having a long side at the base side of the linear spring. When the orientation adjustment recess having a rectangular shape in plan view is formed, the range in which plastic flow occurs on the long side becomes wide, and the range in which plastic flow occurs on the short side becomes narrow. For this reason, according to the present invention employing such a configuration, the range in which plastic flow in the direction of the linear spring on the long side is increased and the plasticity in the direction that does not affect the linear spring on the short side is increased. The range in which flow occurs can be narrowed. Therefore, the influence of plastic flow on a portion different from the linear spring can be reduced as compared with the case where all the sides are formed with the square-shaped posture adjusting recesses having the same length as the long side.

  A fourth invention is a method for manufacturing a timepiece component, wherein a linear spring and a base portion that supports the linear spring are connected to a base material by press working to a base material. And a posture for adjusting the posture of the linear spring by forming a concave portion for posture adjustment with respect to the base portion by pressing and by bringing a part of the base portion to the linear spring by plastic flow. A configuration of having an adjustment step is adopted. According to the present invention employing such a configuration, a part of the base portion is moved toward the linear spring by the plastic flow by forming the posture adjusting recess, thereby adjusting the position of the linear spring. According to the present invention, since the position of the linear spring is adjusted by forming the posture adjusting recess, for example, the position of the linear spring can be adjusted without performing the operation of cutting the insert of the press machine. Can be done.

  According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the posture adjustment step includes forming the posture adjustment recess on the edge of the base portion to which the base of the linear spring is connected. To do. According to the present invention adopting such a configuration, since the posture adjusting recess is formed very close to the linear spring, the influence of plastic flow on the linear spring can be increased, and the posture adjusting Even if the recess is shallow, the position of the linear spring can be easily adjusted.

  According to a sixth aspect of the present invention, in the fourth or fifth aspect of the invention, in the posture adjustment step, the posture adjustment concave portion having a rectangular shape in which a base side of the linear spring has a long side is formed in the posture adjustment step. Adopt the configuration. According to the present invention employing such a configuration, the range in which plastic flow in the direction of the linear spring on the long side is increased, and plastic flow in the direction that does not affect the linear spring on the short side is generated. The range can be narrowed. Therefore, the influence of plastic flow on a portion different from the linear spring can be reduced as compared with the case where all the sides are formed with the square-shaped posture adjusting recesses having the same length as the long side.

  According to a seventh aspect of the present invention, in any one of the fourth to sixth aspects, the posture adjustment step includes forming the posture adjustment recess with a depth corresponding to the posture adjustment amount of the linear spring. To do. The position of the linear spring can be changed by changing the depth of the posture adjusting recess. For this reason, according to the present invention adopting such a configuration, the depth of the posture adjusting recess corresponds to the posture adjustment amount of the linear spring. For this reason, the position of the linear spring can be adjusted more accurately.

  Hereinafter, an embodiment of a timepiece part and a timepiece part manufacturing method according to the present invention will be described with reference to the drawings. In the following drawings, the scale of each member is appropriately changed in order to make each member a recognizable size.

  FIG. 1 is a perspective view illustrating the jumper 1 of the present embodiment and a claw wheel portion 100 that is greatly controlled by the jumper 1 (a watch component). FIG. 2 is an enlarged plan view of a main part illustrating the jumper 1 and the ratchet wheel part 100 of the present embodiment. The jumper 1 and the ratchet wheel part 100 are parts for a timepiece that are disposed between a dial (not shown) and a base plate (not shown) and are accommodated inside the timepiece. The ratchet wheel portion 100 is a gear that rotates together with a date indicator wheel (not shown) and the like, and includes a spur gear in which a plurality of teeth 101 are arranged at equal intervals in the circumferential direction.

  The jumper 1 is formed by pressing a metal plate of 1 mm or less. As shown in FIG. 1, the base portion 2, the spring portion 3 (linear spring), the jumping claw portion 4, and the posture And an adjustment recess 5. The base portion 2 is a substantially annular portion that supports the spring portion 3 and supports the jumping claw portion 4 via the spring portion 3. The base portion 2 is formed with a plurality of openings, and the spring portion 3 and the jumping claw portion 4 are disposed in one of the openings 2a.

  The spring part 3 consists of a very thin linear spring. The spring portion 3 is provided so that the root 3a is integrally connected to the base portion 2 and protrudes inward of the opening portion 2a from an edge portion 2b that forms the outline of the opening portion 2a of the base portion 2. . The base 3 a is smoothly connected so that there is no portion that is bent with respect to the base portion 2 by the curved portion 2 c that is a part of the edge portion 2 b of the base portion 2. Further, the tip 3b of the spring part 3 is integrally connected to the jumping claw part 4, and the spring part 3 has the flexibility to move the jumping claw part 4 in the radial direction of the claw wheel part 100, so The claw part 4 is supported. The flexibility (that is, the thinness) of the spring portion 3 is such that when the torque acting on the claw wheel portion 100 exceeds a predetermined value, the jumping claw portion 4 comes off between adjacent teeth 101 of the claw wheel portion 100. Is set to

  The jumping claw portion 4 has a protruding portion 4a that protrudes toward the claw wheel portion 100, and one side 4b when the protruding portion 4a side is the front surface is connected to the tip 3b of the spring portion 3. ing. The jumping claw portion 4 has a spring portion so that when the spring portion 3 is not bent, the protruding portion 4a is positioned between the adjacent teeth 101 of the claw wheel portion 100 and engages with the teeth 101. 3 is connected. Such a jumping claw portion 4 is engaged with the teeth 101 of the claw wheel portion 100 until the torque acting on the claw wheel portion 100 exceeds a predetermined value, and the torque acting on the claw wheel portion 100 is a predetermined value. If it exceeds, the spring part 3 will bend, and will remove | deviate from between teeth 101, will allow rotation of the ratchet wheel part 100, and it will enter between next teeth 101 with the restoring force of the spring part 3 after that.

  The posture adjusting recess 5 is provided in the curved portion 2c to which the root 3a of the spring portion 3 is connected. This posture adjusting recess 5 is a recess formed by pressing the surface of the base portion 2, and adjusts the posture of the spring portion 3 by bringing a part of the base portion 2 close to the spring portion 3 by plastic flow. It is provided for this purpose. In the present embodiment, the orientation adjusting recess 5 has a rectangular shape with one long side 5a facing the spring portion 3 in plan view, and one short side 5b is provided so as to overlap the curved portion 2c. It has been.

  As described above, when the posture adjusting concave portion 5 is provided so as to overlap the curved portion 2 c, the posture adjusting concave portion 5 is formed very close to the spring portion 3. For this reason, when the part of the base part 2 is plastically flowed, the influence on the spring part 3 becomes large. Therefore, the position of the spring portion 3 can be easily adjusted even if the posture adjusting recess 5 is shallow.

  Further, when the shape of the recess 5 for posture adjustment is a rectangular shape, the range in which plastic flow occurs on the long side 5a is widened, and the short side 5c (the side opposite to the short side 5b overlapped with the curved portion 2c) is increased. The range in which plastic flow occurs on the short side) becomes narrower. Therefore, the influence of the plastic flow toward the short side 5c can be reduced as compared with the case where the posture adjusting recess 5 has a square shape in which all sides are the same as the long side 5a. Therefore, even when there is another functional part (for example, another linear spring) on the short side 5c side, it is possible to suppress the influence of the posture adjusting recess 5 on this functional part. it can.

  Then, the manufacturing method of the jumper 1 of such this embodiment is demonstrated. FIG. 3 is a schematic view of a progressive press unit 10 for manufacturing the jumper 1 of the present embodiment. As shown in this figure, the press unit 10 includes an uncoiler 11, a leveler feeder 12, a press machine 13, and a mold 14.

  The uncoiler 11 is an apparatus for unwinding the metal plate 15 from the coil 16 formed by winding the strip-shaped metal plate 15 (base material) before press working. The leveler feeder 12 is a device for correcting the shape of the metal plate 15 unraveled by the uncoiler 11 and supplying the corrected metal plate 15 to the press machine 13. The leveler feeder 12 feeds the metal plate 15 for one stage of a mold 14 to be described later for each press operation (vertical movement) in the press machine 13.

  The press machine 13 includes a bolster 13a on which the lower mold 14a of the mold 14 is set, and a slide 13b on which the upper mold 14b of the mold 14 is set. It is an apparatus for pressing the metal plate 15 by biting the upper die 14b with the lower die 14a.

  The mold 14 is divided into a plurality of stages 14 c in the feeding direction of the metal plate 15. The shape of the mold 14 is different for each stage 14c, and when the press work is completed in all the stages 14c, the metal plate 15 becomes the jumper 1 of the present embodiment. In FIG. 3, for simplification, the mold 14 is shown as having eight stages 14 c, but actually has, for example, 20 or more stages 14 c. .

  FIG. 4 is a cross-sectional view showing a schematic configuration of the last stage 14 c of the mold 14. As shown in this figure, in the final stage 14c of the mold 14, the upper mold 14b includes a first plate 14d, a second plate 14e, a nest 14f, a spacer 14g, and a collar 14h.

  The first plate 14d forms a lower layer of the upper mold 14b, and has a through-hole 14d1 that passes through in the vertical direction and can accommodate the insert 14f. In addition, the first plate 14d includes an annular locking portion 14i that is provided below the through hole 14d1 and projects toward the inside of the through hole 14d1. The locking portion 14i supports the collar 14h on the upper surface 14j. The second plate 14e forms an upper layer of the upper mold 14b, and is attached to the first plate 14d from above so as to cover the through hole 14d1. The second plate 14e is fastened to the first plate 14d by a bolt (not shown).

  The insert 14f includes a cylindrical base portion 14f1 that can pass through a region surrounded by the locking portion 14i, a protrusion 14f2 that is provided on the lower surface of the base portion 14f1 and projects downward from the lower surface, and the base portion 14f1. And a locking portion 14f3 provided so as to project sideways at the center in the height direction. The protrusion 14f2 is a part that presses the metal plate 15 when the slide 13b of the press machine 13 descends, and forms the attitude adjusting recess 5. The locking portion 14f3 is in contact with the collar 14h at the lower surface 14f4. As a result, the insert 14f is supported by the first plate 14d via the collar 14h.

  The spacer 14g is disposed in the through hole 14d1, and is interposed between the second plate 14e and the insert 14f. The spacer 14g defines the position in the height direction of the protrusion 14f2 of the insert 14f. The spacer 14g defines the pressing amount of the protrusion 14f2 against the metal plate 15, that is, the depth of the attitude adjusting recess 5. The collar 14h is set to a height that fills the gap between the lower surface 14f4 of the locking portion 14f3 and the upper surface 14j of the locking portion 14i, which is determined by the thickness of the spacer 14g first.

  The amount of plastic flow varies depending on the depth of the attitude adjusting recess 5. That is, the amount of movement of the spring portion 3 (see FIGS. 1 and 2) varies depending on the depth of the posture adjusting recess 5. For this reason, for example, a relationship between the depth of the posture adjusting recess 5 and the amount of movement of the spring portion 3 is previously made into a database by experiments, and the database is referred to when posture adjustment of the spring portion 3 is required. It is desirable to determine the thickness of the spacer 14g. Thereby, the thickness of the spacer 14g can be easily determined.

  In the method of manufacturing the jumper 1 according to this embodiment, the metal plate 15 unwound from the coil 16 by the uncoiler 11 is corrected by the leveler feeder 12 and supplied to the press machine 13. The metal plate 15 supplied to the press machine 13 is moved by one stage 14c for each press operation, and is pressed at each stage 14c. As shown in FIG. 5, the base portion 2 and the spring portion 3 are formed on the metal plate 15 by the last stage 14c. That is, in this embodiment, the press work at each stage 14c except the last stage 14c corresponds to the step of forming the spring part and the base part in the present invention.

  Subsequently, the posture adjusting recess 5 is formed on the last stage 14c. Here, when the slide 13b of the press machine 13 is lowered and the lower mold 14a and the upper mold 14b are engaged with each other, the protrusion 14f2 of the insert 14f presses the base 2 as shown in FIG. As a result, a part of the base portion 2 varies due to plastic flow. At this time, as shown in FIG. 7, a part of the base portion 2 is moved toward the spring portion 3 side by plastic flow, so that the spring portion 3 moves, and as indicated by an arrow in FIG. The position of the jumping claw portion 4 is changed in a direction approaching (see FIGS. 1 and 2). Depending on the thickness of the spacer 14g (see FIG. 4), the depth of the posture adjusting recess 5 is set so that the jumping claw portion 4 is moved to an appropriate position. For this reason, the attitude | position of the jumping nail | claw part 4 is adjusted so that the projection part 4a may become an appropriate position. Such a process corresponds to the posture adjustment process of the present invention.

  When the posture adjusting recess 5 is formed, the metal plate 15, that is, the jumper 1 is discharged from the press machine 13. Since the jumper 1 in which the posture adjusting recess 5 is formed is provided in a part of the belt-shaped metal plate 15, it is cut into a predetermined number by, for example, a post-processing device (not shown).

  According to the method of manufacturing the jumper 1 of the present embodiment as described above, the spring portion 3 and the base 3a of the spring portion 3 are connected to the metal plate 15 by pressing and the base portion that supports the spring portion 3 is supported. 2 and forming the posture-adjusting concave portion 5 on the base portion 2 by pressing, so that a portion of the base portion 2 is brought close to the spring portion 3 by plastic flow to thereby change the posture of the spring portion 3. A posture adjusting step for adjusting. According to the manufacturing method of the jumper 1 of this embodiment, a part of the base portion 2 is moved toward the spring portion 3 by plastic flow by forming the posture adjusting recess 5, thereby Adjust the position. According to such a method of manufacturing the jumper 1 of the present embodiment, the position of the spring portion 3 is adjusted by forming the posture adjusting recess 5, so that, for example, the operation of cutting the insert of the press machine 13 is performed. The position of the spring portion 3 can be adjusted without any problem.

  Moreover, in the manufacturing method of the jumper 1 of this embodiment, the attitude | position adjustment recessed part 5 is formed so that it may overlap with the curved part 2c of the base part 2 to which the base 3a of the spring part 3 is connected. For this reason, since the posture adjusting concave portion 5 is formed very close to the spring portion 3, the influence of the plastic flow on the spring portion 3 can be increased, and even if the posture adjusting concave portion 5 is shallow, the spring portion 3 can be made. Can be easily adjusted.

  Further, in the method for manufacturing the jumper 1 of the present embodiment, the rectangular shape adjustment recess 5 is formed in which the shape of the plan view is a rectangular shape in which the base 3a side of the spring portion 3 is the long side 5a. For this reason, the range in which the plastic flow in the direction of the spring part 3 on the long side 5a side can be increased, and the range in which the plastic flow in the direction not affecting the spring part 3 on the short side 5c side can be reduced. Therefore, the influence of plastic flow on a part different from the spring part 3 can be reduced as compared with the case where all the sides form the square-shaped posture adjusting recess 5 having the same length as the long side 5a. .

  Further, in the method for manufacturing the jumper 1 according to the present embodiment, the posture adjustment recess 5 is formed with a depth corresponding to the posture adjustment amount of the spring portion 3. For this reason, the depth of the recessed portion 5 for posture adjustment corresponds to the posture adjustment amount of the spring portion 3, and the position of the linear spring can be adjusted more accurately.

  Hereinafter, the jumper 1 of this embodiment and the modification of the manufacturing method of this jumper 1 are demonstrated.

In the above-described example, the posture adjusting concave portion 5 is provided on the lower side of the spring portion 3 in the figure (the side opposite to the side where the protruding portion 4a of the jumping claw portion 4 is provided). However, as shown in FIG. 11, the posture adjusting recess 5 may be provided on the upper side of the spring portion 3 in the drawing (the side on which the protrusion 4 a of the jumping claw portion 4 is provided). In this case, when the spring portion 3 is moved by the posture adjusting recess 5, the protrusion 4a of the jumping claw portion 4 is moved away from the claw wheel portion 100 (see FIGS. 1 and 2). . In this modified example, the position of the posture adjusting recess 5 is different from that in the above example. Therefore, for example, a stage 14c for forming the posture adjusting recessed portion 5 in another modified example is provided on the mold 14.
