Description

Technical Field

[0001] This utility model relates to the field of hairspring production technology, and in particular to a stamping die for a car instrument hairspring. Background Technology

[0002] The hairspring is a key component of the regulating system of a mechanical watch. It works with the balance wheel to form an oscillation system. Through elastic deformation, it controls the isochronous reciprocating motion of the balance wheel, thereby adjusting the timekeeping accuracy. Its oscillation period directly affects how fast or slow the watch runs; the larger the period, the slower the watch runs, and vice versa. There are many types of hairsprings in production, among which stamping is the most common. Stamping is the type of hairspring with higher strength, and therefore a longer service life.

[0003] The existing method of hairspring stamping involves moving the raw material along the mold, then having the stamping head press the raw material along the mold to form it. After the raw material is stamped, it is taken out of the mold and transferred again for stamping.

[0004] However, after stamping, the formed hairspring must be manually removed from the mold each time. The hairspring is small in shape and requires tweezers to be used to remove it vertically from the mold, which makes it difficult to remove the hairspring and affects production efficiency. Therefore, this application proposes a stamping mold for a car instrument hairspring. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art where, after stamping, the formed hairspring must be manually removed from the mold each time. The hairspring is small in shape and requires tweezers to vertically remove it from the mold, which makes hairspring removal difficult and affects production efficiency. This invention proposes a stamping mold for automotive instrument hairsprings.

[0006] The technical solution of this utility model is as follows: A stamping die for a car instrument clock spring includes a swing rod, a die table is fixedly connected to one side of the swing rod in an inclined shape, a die body is fixedly connected to one end of the die table, a pressing rod is provided above the swing rod, a stamping head is fixedly connected to one side of the pressing rod, a rotating groove is provided inside the swing rod and the die table, and a support component is provided inside the rotating groove.

[0007] Optionally, the support assembly includes a support rod rotatably connected inside the rotating groove, a support plate fixedly connected to the end of the support rod away from the rotating groove, and a reset assembly provided on the side of the mold table away from the swing rod.

[0008] Optionally, the reset assembly includes a worm spring, with a connecting block fixedly connected to one end of the worm spring near the outside, and a rotating rod fixedly connected to one end of the worm spring near the inside, the rotating rod being fixedly connected to one side of the mold table.

[0009] Optionally, a fixing plate is fixedly connected to the side of the connecting block away from the mold table, and the end of the rotating rod away from the mold table is rotatably connected to the side of the fixing plate. A base is fixedly connected to the bottom of the fixing plate and the support plate.

[0010] Optionally, the swing rod is trapezoidal, the pressing rod is positioned closer to the swing rod than the stamping head, and both ends of the pressing rod are arc-shaped.

[0011] Optionally, a base platform is fixedly connected to the bottom of the base, and a support frame is fixedly connected to the top of the base platform near the base. The support frame is arranged in an inverted "L" shape.

[0012] Optionally, a telescopic rod is fixedly connected to the bottom of the support frame, and the output end of the telescopic rod is fixedly connected to the top of the stamping head.

[0013] Compared with the prior art, this application includes at least one of the following beneficial technical effects: by pressing down with a punch head, the oscillating rod and the mold table are simultaneously oscillating, allowing the punch head to punch the mold body at one end of the mold table, thus forming the raw material. After the pressing rod disengages, the worm spring will drive the mold table and the oscillating rod to return to their original positions, achieving the effect of easily removing the formed hairspring. This solves the problem of the previous single vertical punching, which required the use of tweezers to remove the hairspring from the mold, making it difficult to remove the hairspring after each punching, thus improving the convenience of hairspring removal.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 3 As shown, the present invention proposes a stamping die for a car instrument clock spring, including a swing rod 1. A die platform 2 is fixedly connected to one side of the swing rod 1 at an incline. A die body 3 is fixedly connected to one end of the die platform 2. A pressing rod 5 is set above the swing rod 1. The pressing rod 5 pushes the swing rod 1 to change its angle. A stamping head 4 is fixedly connected to one side of the pressing rod 5. The downward movement of the stamping head 4 also drives the pressing rod 5 to move downward. A rotating groove 16 is opened inside the swing rod 1 and the die platform 2. A support assembly is set inside the rotating groove 16. The support assembly includes a support rod 9. The support rod 9 can ensure that the swing rod 1 and the die platform 2 can rotate by relying on the rotating groove 16. The support rod 9 is rotatably connected inside the rotating groove 16. A support plate 10 is fixedly connected to the end of the support rod 9 away from the rotating groove 16. The support plate 10 can cooperate with the support rod 9 to support the swing rod 1 and the die platform 2. A reset assembly is set on the side of the die platform 2 away from the swing rod 1.

[0022] in addition Figure 4 and Figure 5 As shown, the reset assembly includes a worm spring 6. A connecting block 15 is fixedly connected to the outer end of the worm spring 6, and a rotating rod 7 is fixedly connected to the inner end of the worm spring 6. When the worm spring 6 rotates, it will cause the worm spring 6 to rewind. The worm spring 6 is elastic and can also drive the rotating rod 7, the mold table 2, and the swing rod 1 to reset. The rotating rod 7 is fixedly connected to one side of the mold table 2. A fixing plate 8 is fixedly connected to the side of the connecting block 15 away from the mold table 2. The end of the rotating rod 7 away from the mold table 2 is rotatably connected to one side of the fixing plate 8. The fixing plate 8 can cooperate with the support plate 10 to support the mold table 2 and the equipment that assists the operation of the mold table 2. A base 11 is fixedly connected to the bottom of the fixing plate 8 and the support plate 10.

[0023] also Figure 1 , Figure 2 As shown, the swing rod 1 is trapezoidal in shape. The trapezoidal structure of the swing rod 1 allows the swing rod 1 to gradually drive the mold table 2 to swing. The position of the pressing rod 5 is closer to the swing rod 1 than the stamping head 4. The two ends of the pressing rod 5 are arc-shaped. The arc-shaped structure of the pressing rod 5 can press down along the trapezoidal bevel of the swing rod 1, thereby allowing the swing rod 1 to change angle. The bottom of the base 11 is fixedly connected to the base platform 14. The base platform 14 facilitates the operation of the above parts. The top of the base platform 14 is fixedly connected to the support frame 13 near the base 11. The support frame 13 is inverted "L" shape. The "L" shape of the support frame 13 facilitates the placement and removal of the support position and the operation position. The bottom of the support frame 13 is fixedly connected to the telescopic rod 12. The output end of the telescopic rod 12 is fixedly connected to the top of the stamping head 4. The stamping head 4 can be controlled to perform stamping operation at the bottom of the support frame 13 through the telescopic rod 12.

[0024] In this embodiment, during stamping, the raw material is placed on top of the mold body 3. At this time, the telescopic rod 12 can drive the stamping head 4 and the pressing rod 5 downward under the support of the support frame 13. The arc-shaped position of the pressing rod 5 will contact the inclined surface of the swing rod 1. As the stamping head 4 continues to move downward, it will move along the inclined surface of the swing rod 1 to the plane. In this way, the swing rod 1 will drive the mold table 2 to change angle and become vertical. After the pressing rod 5 pushes the swing rod 1 to the final position, the stamping head 4 can stamp the raw material with the mold body 3 at one end of the mold table 2.

[0025] After the raw material is stamped, the telescopic rod 12 drives the stamping head 4 and the lowering rod 5 to move upward. The swing rod 1 and the mold table 2 will rotate inside the rotating groove 16 with the support rod 9. The rotating rod 7 rotates in conjunction with the mold table 2 and the swing rod 1. The support plate 10 and the fixing plate 8 are fixed on the top of the base 11 to support the swing rod 1 and the mold table 2. When the lowering rod 5 gradually separates from the swing rod 1, the worm spring 6 gradually releases its elasticity by relying on the connecting block 15, so that the worm spring 6 drives the rotating rod 7 to rotate, making the swing rod 1 tend to be vertical. The mold table 2 returns to its tilted position, so that the stamped raw material can be removed from the position of the mold body 3.

[0026] When the mold body 3 is stamping, the base 11 can move on the parts fixedly supported by the base 11 on the top of the base 14, and the support frame 13 is also supported by the base 14, so that the telescopic rod 12 controls the stamping head 4 to stamp.

[0027] It should be noted that this device uses a pressing head 4 to press down, while simultaneously driving the swing rod 1 and the mold table 2 to swing, allowing the pressing head 4 to press the mold body 3 at one end of the mold table 2. This allows the raw material to be pressed into shape. After the pressing rod 5 disengages, the worm spring 6 will drive the mold table 2 and the swing rod 1 to return to their original positions, achieving the effect of easily removing the formed hairspring. This solves the problem of the previous single vertical pressing method, which required the use of tweezers to remove the hairspring from the mold body 3, making it difficult to remove the hairspring after each pressing. This device improves the convenience of hairspring removal.

[0028] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
