Description

Technical Field

[0001] This utility model relates to the field of precious metal bracelet processing technology, specifically a precious metal bracelet shaping machine. Background Technology

[0002] Precious metal bracelet processing refers to the process of using precious metals such as gold, silver, platinum, and palladium as the main raw materials, and through a series of specific processes and techniques, to make bracelet products with specific styles, sizes, and qualities to meet the needs of wearing, decoration, and collection. The following is a breakdown of the processing process and its purpose.

[0003] A prior patent (publication number: CN221869806U) discloses a precious metal bracelet shaping machine, which includes a rotating mechanism, a driving mechanism, and a shaping mechanism. The rotating mechanism drives the bracelet to rotate, and the shaping mechanism includes a base and two correction components. Both correction components are mounted on the base and spaced apart to form a correction space. The driving mechanism is connected to the base and drives the correction space to engage or disengage from the bracelet. This invention utilizes a rotating mechanism to control the bracelet's rotation. By coordinating the driving mechanism and the shaping mechanism, the correction components press against the bracelet surface within the correction space, effectively smoothing the uneven surface of the bracelet. A smooth surface facilitates polishing, thereby effectively improving the polishing effect.

[0004] During use, the aforementioned shaping machine can correct the way the components squeeze and correct the surface of the bracelet within the correction space, which helps to smooth the uneven surface of the bracelet. A smooth surface of the bracelet is conducive to polishing, thereby effectively improving the polishing effect. However, during the shaping process, the bracelet is driven to rotate, and then two shaping rods are used to contact the bracelet to achieve shaping. However, the contact area between the two shaping rods and the bracelet is small. This results in the bracelet surface being subjected to relatively concentrated pressure during the shaping process. For some precious metal bracelets that are softer or have a greater degree of deformation, this concentrated force may cause localized excessive compression deformation on the bracelet surface, or even leave indentations that are difficult to remove, affecting the overall aesthetics and quality of the bracelet. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a precious metal bracelet shaping machine, which has advantages such as uniform shaping and solves the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a precious metal bracelet shaping machine, comprising a base and an arc-shaped frame fixedly connected to the side of the base, two rubber clamping wheels rotatably connected to the inner wall of the arc-shaped frame, an inductive sensor installed on the inner wall of the arc-shaped frame, a swing arm rotatably connected to the other side of the base, a second rubber clamping wheel rotatably connected to the upper end of the swing arm, and the bottom end of the swing arm fixedly connected to the output end of an external motor;

[0007] The base has a rotatable arc-shaped ring inside, and two corresponding sliding cylinders are slidably connected to the inner wall of the arc-shaped ring. Sliding rods are slidably connected to the inside of the two sliding cylinders along their axial direction. Each sliding rod is fixedly connected to the corresponding sliding cylinder by a spring. A set of corrective bars is fixedly connected to one end of each of the two sliding rods.

[0008] Furthermore, the adjustment component includes an arc-shaped slider that is rotatably connected to the inner wall of the arc-shaped ring. The inner wall of the arc-shaped slider is fixedly connected to two arc-shaped protrusions. The other ends of the two slide cylinders are both spherical and in contact with the corresponding arc-shaped protrusions. The side of the arc-shaped slider is provided with a plurality of circumferentially distributed positioning grooves. The side of the arc-shaped ring is fixedly connected to an elastic metal sheet, which is located in the corresponding positioning groove.

[0009] By rotating the arc-shaped sliding component and utilizing the contact between the arc-shaped protrusion on its inner wall and the spherical end of the sliding cylinder, the position of the sliding cylinder within the arc-shaped ring can be precisely changed, thereby adjusting the distance between the sliding rod and the correcting rod and the bracelet, and achieving flexible adjustment of the pressure of the correcting rod on the bracelet.

[0010] Furthermore, the inner wall of the base is fixedly connected to a slide rail with an arc-shaped upper end, the arc-shaped ring is slidably connected to the slide rail, and a rectangular groove is formed on the upper surface of the slide rail.

[0011] With the above solution, the slide rail fixedly connected to the inner wall of the base provides a stable motion track for the arc ring. During the rotation of the arc ring, the sliding connection with the slide rail ensures the accuracy and stability of its motion trajectory, avoiding swaying or deviation.

[0012] Furthermore, the drive assembly includes a toothed plate slidably connected to the inner bottom wall of the base. A set of circumferentially distributed teeth are fixedly connected to the outer surface of the arc-shaped ring. The toothed plate meshes with the corresponding teeth. A sliding plate is fixedly connected to the bottom end of the toothed plate. A slot is formed on the bottom surface of the sliding plate along its length. A drive motor is fixedly installed on the inner bottom wall of the base. A Z-shaped swing plate is fixedly connected to the output end of the drive motor. The upper end of the swing plate is located in the slot and slidably connected to the inner top wall of the slot.

[0013] Through the above scheme, the drive motor drives the Z-shaped swing plate to swing. The upper end of the swing plate moves in the groove of the sliding plate, thereby pushing the sliding plate and the toothed plate to perform reciprocating linear motion. The toothed plate meshes with the teeth on the outer surface of the arc ring, converting the linear motion into the rotational motion of the arc ring, thus realizing the driving of the arc ring.

[0014] Furthermore, the inner wall of the base is provided with a sliding groove, and the sliding plate is slidably connected along the inner wall of the sliding groove.

[0015] With the above solution, the sliding plate slides along the inner wall of the sliding groove, which can ensure the accuracy of its movement direction and prevent the sliding plate from deviating or getting stuck during the movement.

[0016] Furthermore, the base has notches on both sides along its length, and both notches are adapted to the toothed plate.

[0017] The above solution provides space for the movement of the toothed plate, allowing it to move freely in a reciprocating linear motion under the drive of the drive assembly without being obstructed by the base.

[0018] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0019] This precious metal bracelet shaping machine, through the setting of rubber extrusion rollers, can clamp bracelets of different sizes under the drive of the swing arm. The addition of inductive sensors can prevent the bracelet from deforming due to excessive force. Secondly, the rotation of the arc ring driven by the drive component can make the two sets of straightening rods evenly contact the bracelet and shape it, preventing stress concentration from causing deformation, thereby improving the shaping quality of the bracelet.

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please see Figures 1-6 The precious metal bracelet shaping machine in this embodiment includes a base 1 and an arc-shaped frame 2 fixedly connected to the side of the base 1. Two rubber clamping wheels 3 are rotatably connected to the inner wall of the arc-shaped frame 2. One of the rubber clamping wheels is fixedly connected to the output end of an external motor. An inductive sensor 4 is installed on the inner wall of the arc-shaped frame 2. A swing arm 5 is rotatably connected to the other side of the base 1. A second rubber clamping wheel 6 is rotatably connected to the upper end of the swing arm 5, and the bottom end of the swing arm 5 is fixedly connected to the output end of an external motor. Through the cooperation of the first rubber clamping wheel 3 and the second rubber clamping wheel 6, different types of precious metal bracelets can be shaped. The size of the bracelet is fixed, and the addition of the inductive sensor 4 can prevent the bracelet from deforming due to excessive pressure, and can drive the bracelet to rotate in the base 1. The base 1 is equipped with a drive component 7. When the inductive sensor 4 is close to the bracelet, it can send a signal to the external control device when the bracelet approaches the inductive sensor 4 and exceeds the threshold. This causes the external control device to stop the motor controlling the rotation of the swing arm 5, thus preventing the bracelet from deforming due to excessive contact pressure between the rubber contact wheel 6 and the bracelet.

[0036] The base 1 has a rotatable arc-shaped ring 8 inside. Two corresponding sliding cylinders 9 are slidably connected to the inner wall of the arc-shaped ring 8. Sliding rods 10 are slidably connected to the inside of the two sliding cylinders 9 along their axial direction. Each sliding rod 10 is fixedly connected to the corresponding sliding cylinder 9 by a spring. A set of straightening rods 11 is fixedly connected to one end of each of the two sliding rods 10. The straightening rods 11 can make uniform contact with the bracelet during the rotation of the arc-shaped ring 8. The rotation of the straightening rods 11 makes uniform contact with the surface of the bracelet, preventing stress concentration and affecting the straightening quality of the bracelet. The arc-shaped ring 8 has an adjustment component 12 for adjusting the pressure on the bracelet.

[0037] The adjustment assembly 12 includes an arc-shaped slider 1201 rotatably connected to the inner wall of the arc-shaped ring 8. Two arc-shaped protrusions 1202 are fixedly connected to the inner wall of the arc-shaped slider 1201. The other ends of the two slide cylinders 9 are spherical and contact the corresponding arc-shaped protrusions 1202. Multiple circumferentially distributed positioning grooves 1203 are opened on the side of the arc-shaped slider 1201. An elastic metal sheet 1204 is fixedly connected to the side of the arc-shaped ring 8. The elastic metal sheet 1204 is located in the corresponding positioning groove 1203. By rotating the arc-shaped slider 1201, the position of the slide cylinder 9 in the arc-shaped ring 8 can be accurately changed by using the contact between the arc-shaped protrusions 1202 on its inner wall and the spherical end of the slide cylinder 9. This allows for the adjustment of the distance between the slide rod 10 and the correcting rod 11 and the bracelet, thereby achieving flexible adjustment of the pressure of the correcting rod 11 on the bracelet.

[0038] A slide rail 13 with an arc-shaped upper end is fixedly connected to the inner wall of the base 1. The arc-shaped ring 8 is slidably connected to the slide rail 13. The slide rail 13 fixedly connected to the inner wall of the base 1 provides a stable motion track for the arc-shaped ring 8. During the rotation of the arc-shaped ring 8, the sliding connection with the slide rail 13 ensures the accuracy and stability of its motion trajectory, avoiding shaking or deviation. The drive assembly 7 includes a toothed plate 701 slidably connected to the inner bottom wall of the base 1. A set of circumferentially distributed teeth 702 is fixedly connected to the outer surface of the arc-shaped ring 8. The toothed plate 701 meshes with the corresponding teeth 702. A rectangular groove is formed on the upper surface of the slide rail 13. A sliding plate 703 is fixedly connected to the bottom end of the toothed plate 701. The protruding part on the upper surface of the sliding plate 703 is slidably connected to the inner top wall of the rectangular groove for sliding. The sliding plate 703 is limited to ensure stable linear reciprocating motion. The bottom surface of the sliding plate 703 has a slot 704 along its length. A drive motor 705 is fixedly installed on the inner bottom wall of the base 1. A Z-shaped swing plate 706 is fixedly connected to the output end of the drive motor 705. The upper end of the swing plate 706 is located in the slot 704 and is slidably connected to the inner top wall of the slot 704. The drive motor 705 drives the Z-shaped swing plate 706 to swing. The upper end of the swing plate 706 moves in the slot 704 of the sliding plate 703, thereby pushing the sliding plate 703 and the toothed plate 701 to perform reciprocating linear motion. The toothed plate 701 meshes with the teeth 702 on the outer surface of the arc ring 8, converting the linear motion into the rotational motion of the arc ring 8, thus realizing the driving of the arc ring 8.

[0039] The inner wall of the base 1 is provided with a sliding groove 14, and the sliding plate 703 is slidably connected along the inner wall of the sliding groove 14. The sliding plate 703 can slide along the inner wall of the sliding groove 14 to ensure the accuracy of its movement direction and prevent the sliding plate 703 from deviating or jamming during the movement. The base 1 has notches 15 on both sides along the length direction. Both notches 15 are adapted to the toothed plate 701. The notches 15 provide movement space for the toothed plate 701, so that the toothed plate 701 can freely make reciprocating linear motion under the drive of the drive component 7 without being obstructed by the base 1.

[0040] The working principle of the above embodiment is as follows: First, the bracelet is placed between two rubber clamping wheels 3. Then, an external motor drives the swing arm 5 to swing, so that the second rubber clamping wheel 6 contacts the bracelet. Subsequently, the bracelet will move closer to the inductive sensor 4. After the inductive sensor 4 senses the bracelet by a threshold set in advance, the external control device can stop the swing arm 5 by controlling the external motor. Since the rubber clamping wheel is made of elastic material, there will be a gap between the inductive sensor 4 and the bracelet after the swing arm 5 stops working, preventing the bracelet from being scratched.

[0041] Once the bracelet is fixed, rotating the arc-shaped slider 1201 allows the arc-shaped protrusion 1202 to push the slide cylinder 9 to move linearly within the arc-shaped plate, adjusting the distance between the two straightening rods 11 so that it can be used to shape bracelets of different sizes. When the slide cylinder 9 slides, it can compress the spring, causing the slide rod 10 to push the straightening rod 11 into contact with the bracelet. Under the action of the spring, rigid contact between the straightening rod 11 and the bracelet can be prevented, thus preventing damage to the bracelet.

[0042] Subsequently, the drive motor 705 drives the bottom end of the swing plate 706 to rotate, causing the upper end of the swing plate 706 to slide in the slot 704, thereby driving the sliding plate 703 to make linear reciprocating motion in the sliding groove 14. When the sliding plate 703 slides in the sliding groove 14, it can drive the toothed plate 701 to make reciprocating linear motion. Through the meshing of the toothed plate 701 and the teeth 702, the arc plate can make reciprocating rotation, thereby driving the two straightening rods 11 to evenly straighten the bracelet, thereby achieving the purpose of uniform shaping and preventing stress concentration from causing deformation of the bracelet.
