Description

Technical Field

[0001] This application relates to the field of continuous die technology, specifically an ultra-thin integrated stamping structure for a circuit breaker switch copper tube. Background Technology

[0002] A circuit breaker is a switching device that can close, carry, and interrupt current under normal circuit conditions and close, carry, and interrupt current under abnormal circuit conditions within a specified time. A circuit breaker consists of multiple components, including a copper tube welded onto a capacitor for inserting capacitor leads. The copper tube is a deep cylindrical shape with an opening at one end and a closed end at the other. The open end of the copper tube has a flange.

[0003] An existing patent (publication number: CN216461198U) discloses an ultra-thin stamping die for a circuit breaker switch copper tube, which includes an upper die and a lower die. The upper die includes an upper template and multiple punches disposed on the upper template. The lower die includes a lower template and multiple dies disposed on the lower template. The punches and dies correspond one-to-one. The die includes a die base connected to the lower template and a die bottom slider for limiting the bottom shape of the copper tube. The die base has a die cavity groove for limiting the circumferential shape of the copper tube. The die bottom slider is slidably connected to the inner wall of the die cavity groove along the axis of the punches. A lower adjusting plate is provided at the bottom of the die bottom slider, and the lower adjusting plate is provided with a lower adjusting part for adjusting the distance between the lower adjusting plate and the die base.

[0004] The aforementioned prior art documents indicate that this application has the effect of making the height of the lower adjustment plate adjustable, changing the height of the die bottom slider, and thus changing the length of the stamped copper tube. Different lengths of copper tubes can be processed using a single mold, reducing production costs. However, the mold achieves fine-tuning of height through the lower adjustment part on the lower adjustment plate. In actual production environments, if it is necessary to adjust the height of the die bottom sliders of multiple dies simultaneously to match the production requirements of copper tubes of different specifications, the operator may need to adjust the bolts under each die one by one. This is not only cumbersome, but also prone to inconsistent adjustment accuracy due to human factors, which in turn affects the accuracy of the copper tube. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides an ultra-thin integrated stamping structure for circuit breaker switch copper tubes, which offers advantages such as improved production precision and easier adjustment. It solves the problem that in actual production environments, when the height of multiple die bottom sliders needs to be adjusted simultaneously to match the production requirements of copper tubes of different specifications, the operator may need to adjust the bolts under each die individually. This is not only cumbersome but also prone to inconsistent adjustment precision due to human factors, thus affecting the accuracy of the copper tubes.

[0006] To achieve the above objectives, this application provides the following technical solution: an ultra-thin integrated stamping structure for a circuit breaker switch copper tube, comprising a lower plate, an upper plate, and four movable columns. The bottom end of the upper plate is fixedly connected to four punches arranged in a linear array. The upper end of the lower plate has four mounting slots arranged in a linear array. Each of the four mounting slots has a fixed die connected inside. The bottom end of each of the four mounting slots is fixedly connected to a fixing cavity. The inner wall of each of the four fixing cavities has four sliding grooves arranged in a ring array. The upper end of each of the four movable columns is fixedly connected to an adjusting column. The outer wall of each of the four movable columns is fixedly connected to four sliders arranged in a ring array. The four movable columns have internal threaded holes. Each of the four internal threaded holes has a threaded post threaded inside. The bottom end of each of the four threaded posts is fixedly connected to a driven gear. Motors are fixedly connected to both sides of the lower plate. The output ends of two of the motors are fixedly connected to driving gears. The outer walls of the two driving gears are rotatably connected to a transmission belt.

[0007] The above scheme uses a motor to drive the drive gear, which in turn drives the driven gear to rotate via a transmission belt. This allows the threaded column on the driven gear to move up and down within the internal threaded hole of the moving column. The electric adjustment method not only improves work efficiency but also enables precise control of the height of the moving column, thus ensuring the forming accuracy of the copper tube during the stamping process. The design of the mounting groove and fixed cavity on the lower plate, as well as the cooperation between the slider and the groove on the moving column, form a stable guiding and supporting structure. By adjusting the height of the moving column, it is easy to adapt to the processing needs of copper tubes of different lengths. This flexibility allows the same set of molds to be used to produce copper tubes of various specifications, reducing production costs and improving production efficiency.

[0008] Furthermore, the bottom end of the upper plate is fixedly connected to four mounting bases arranged in a rectangular array. Each of the four mounting bases is fixedly connected to a spring and a guide rod at its bottom end, and each of the four springs is fixedly connected to a baffle at the end away from the mounting base.

[0009] Through the above scheme, the spring and guide rod fixedly connected to the mounting base at the bottom of the upper plate, and the baffle connected to the other end of the spring, form an effective buffer and shock absorption system. During the stamping process, when the punch and die contact and apply pressure, the spring can absorb part of the impact force, reduce the impact on the mold and equipment, thereby protecting the mold and equipment from damage and extending their service life. After the stamping is completed, the spring force can push the upper plate to quickly return to its original position, preparing for the next stamping.

[0010] Furthermore, a guide rod seat is fixedly connected to the upper end of the lower plate.

[0011] Through the above scheme, the design of the guide rod seat provides stable support and guidance for the guide rod. During the stamping process, the upper plate cooperates with the guide rod seat on the lower plate through the guide rod on the mounting seat, ensuring the stable movement of the upper plate in the vertical direction and avoiding poor stamping caused by offset or shaking.

[0012] Furthermore, a support base is fixedly connected to the bottom end of the lower plate.

[0013] Through the above scheme, the design of the support base provides a stable support foundation for the entire stamping equipment. It can firmly fix the lower plate and all the components on it to the ground, preventing the equipment from shaking or tilting due to uneven force or vibration during the stamping process. This is crucial for ensuring the accuracy and consistency of the stamped products.

[0014] Furthermore, all four fixing cavities are fixedly disposed inside the die cavity.

[0015] By setting the fixed cavity inside the die using the above method, the height of the adjusting column can be flexibly adjusted according to different stamping requirements and copper tube specifications. This helps to enhance the adaptability of the die, making it suitable for more types of copper tube stamping operations.

[0016] Furthermore, all four movable columns are slidably disposed inside the fixed cavity, and all the multiple sliders are slidably disposed inside the slide groove.

[0017] The above scheme, with the sliding arrangement of the moving column in the fixed cavity and the sliding arrangement of the slider in the slide groove, together constitutes a precise guiding system, ensuring the stability and accuracy of the moving column during the lifting process and avoiding poor stamping caused by deviation or shaking.

[0018] Furthermore, all four guide rods are slidably disposed inside the guide rod seat.

[0019] The above solution provides a precise guiding path for the sliding arrangement of the guide rod within the guide rod seat, ensuring the stability and accuracy of the upper plate and its connected components during the lifting process. This design helps reduce stamping defects caused by offset or swaying, improving the precision and consistency of stamped products. The sliding arrangement of the guide rod and guide rod seat simplifies the mold installation and debugging process. Operators only need to insert the guide rod into the guide rod seat to achieve precise alignment between the upper and lower plates without complex adjustments, which helps improve production efficiency.

[0020] Furthermore, all four driven gears mesh with the inner wall of the transmission belt.

[0021] The above scheme ensures the continuity and efficiency of power transmission by meshing the driven gear with the inner wall of the transmission belt, thereby driving multiple driven gears to rotate simultaneously and adjusting the adjusting columns inside multiple fixed cavities at the same time.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This circuit breaker switch copper tube ultra-thin integrated stamping structure uses a motor to drive a drive gear, which in turn drives a driven gear to rotate via a transmission belt. This allows the threaded column on the driven gear to rise and fall within the internal threaded hole of the moving column. The electric adjustment method not only improves work efficiency but also enables precise control of the moving column height, thus ensuring the forming accuracy of the copper tube during stamping. The mounting groove and fixed cavity design on the lower plate, as well as the sliding block and groove cooperation on the moving column, form a stable guiding and supporting structure. By adjusting the height of the moving column, it can easily adapt to the processing needs of copper tubes of different lengths. This flexibility allows the same set of molds to be used to produce copper tubes of various specifications, reducing production costs and improving production efficiency. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes an ultra-thin integrated stamping structure for a circuit breaker switch copper tube, comprising a lower plate 1, an upper plate 2, and four movable columns 8. The bottom of the upper plate 2 is fixedly connected to four punches 3 arranged in a linear array. The upper end of the lower plate 1 has four mounting grooves 4 arranged in a linear array. Each of the four mounting grooves 4 has a die 5 fixedly connected inside. The bottom of each of the four mounting grooves 4 is fixedly connected to a fixing cavity 6. The inner wall of each of the four fixing cavities 6 has four sliding grooves 7 arranged in a ring array. The upper end of each of the four movable columns 8 is fixedly connected to an adjusting column 9. The outer wall of each of the four movable columns 8 is fixedly connected to four sliders 10 arranged in a ring array. The four movable columns 8 have internal threaded holes 11 inside. Each internal threaded hole 11 is threaded with a threaded post 12. The bottom of each of the four threaded posts 12 is fixedly connected to a driven gear 13. Both sides of the lower plate 1 are fixedly connected to motors 14. The output ends of the two motors 14 are fixedly connected to driving gears 15. The outer walls of the two driving gears 15 are rotatably connected to transmission belts 16. The motors 14 drive the driving gears 15, which in turn drive the driven gears 13 to rotate through the transmission belts 16. This allows the threaded posts 12 on the driven gears 13 to rise and fall within the internal threaded holes 11 of the moving posts 8. The electric adjustment method not only improves work efficiency but also achieves precise control of the height of the moving posts 8, thereby ensuring the forming accuracy of the copper tube during the stamping process.

[0032] Please see Figure 1 and Figure 2 Four mounting bases 17 arranged in a rectangular array are fixedly connected to the bottom end of the upper plate 2. Each of the four mounting bases 17 has a spring 18 and a guide rod 19 fixedly connected to its bottom end. A baffle 20 is fixedly connected to the end of each spring 18 away from the mounting base 17. The springs 18 and guide rods 19 fixedly connected to the mounting bases 17 at the bottom end of the upper plate 2, along with the baffle 20 connected to the other end of the springs 18, form an effective buffer and shock absorption system. During the stamping process, when the punch 3 contacts the die 5 and applies pressure, the springs 18 can absorb part of the impact force, reducing the impact on the die. The upper plate 2 is protected from impacts to the equipment, thus protecting the mold and equipment from damage and extending their service life. After stamping, the elastic force of the spring 18 can push the upper plate 2 to quickly return to its original position, preparing for the next stamping. The upper end of the lower plate 1 is fixedly connected to the guide rod seat 21. The design of the guide rod seat 21 provides stable support and guidance for the guide rod. During the stamping process, the upper plate 2 cooperates with the guide rod seat 21 on the lower plate 1 through the guide rod 19 on the mounting seat 17, ensuring the stable movement of the upper plate 2 in the vertical direction and avoiding poor stamping caused by offset or shaking.

[0033] Please see Figure 2 , Figure 3 and Figure 4A support base 22 is fixedly connected to the bottom of the lower plate 1. The design of the support base 22 provides a stable support foundation for the entire stamping equipment. It can firmly fix the lower plate 1 and all its components to the ground, preventing the equipment from shaking or tilting due to uneven force or vibration during the stamping process. This is crucial for ensuring the accuracy and consistency of the stamped products. Four fixed cavities 6 are fixedly set inside the die cavity 5. By setting the fixed cavities 6 inside the die cavity 5, the height of the adjusting column 9 can be flexibly adjusted according to different stamping requirements and copper tube specifications. This helps to enhance the adaptability of the mold, making it suitable for more types of copper tube stamping operations. Four moving columns 8 are slidably set inside the fixed cavities 6, and multiple sliders 10 are slidably set inside the slide grooves 7. The sliding setting of the moving columns 8 in the fixed cavities 6 and the sliding setting of the sliders 10 in the slide grooves 7 together constitute a precise guiding system, ensuring the stability and accuracy of the moving columns 8 during the lifting process and avoiding... To prevent stamping defects caused by misalignment or wobbling, all four guide rods 19 are slidably disposed inside the guide rod seat 21. The sliding arrangement of the guide rods 19 within the guide rod seat 21 provides a precise guiding path, ensuring the stability and accuracy of the upper plate 2 and its connected components during lifting. This design helps reduce stamping defects caused by misalignment or wobbling, improving the precision and consistency of the stamped products. The sliding arrangement of the guide rods 19 and the guide rod seat 21 simplifies the mold installation and debugging process. Operators only need to insert the guide rods 19 into the guide rod seat 21 to achieve precise alignment between the upper plate 2 and the lower plate 1, without the need for complex adjustments. This helps improve production efficiency. All four driven gears 13 mesh with the inner wall of the transmission belt 16. The meshing design between the driven gears 13 and the inner wall of the transmission belt 16 ensures the continuity and efficiency of power transmission, driving multiple driven gears 13 to rotate simultaneously, and simultaneously adjusting the adjusting columns 9 inside multiple fixed cavities 6.

[0034] In this embodiment, the ultra-thin integrated stamping structure of the copper tube for circuit breakers is driven by a motor 14 to drive a drive gear 15, which in turn drives a driven gear 13 to rotate via a transmission belt 16. This allows the threaded post 12 on the driven gear 13 to move up and down within the internal threaded hole 11 of the moving post 8. The electric adjustment method not only improves work efficiency but also enables precise control of the height of the moving post 8, thereby ensuring the forming accuracy of the copper tube during the stamping process. The design of the mounting groove 4 and the fixed cavity 6 on the lower plate 1, as well as the cooperation between the slider 10 and the slide groove 7 on the moving post 8, form a stable guiding and supporting structure. By adjusting the height of the moving post 8, it is easy to adapt to the processing requirements of copper tubes of different lengths. This flexibility allows the same set of molds to be used to produce copper tubes of various specifications, reducing production costs and improving production efficiency.

[0035] It should be noted that the interior of the multiple adjusting columns 9 is hollow, allowing the threaded column 12 to slide inside the adjusting column 9.

[0036] The working principle of the above embodiments is as follows:

[0037] First, according to the specifications of the copper tube to be processed, the height of the four moving columns 8 is adjusted. This is achieved by the motor 14 driving the drive gear 15 to rotate, which in turn drives the driven gear 13 to rotate via the transmission belt 16. The rotation of the driven gear 13 causes the threaded column 12 to rotate in the internal threaded hole 11 of the moving column 8, thereby driving the moving column 8 to rise and fall, thus adjusting the height of the moving column 8. After the adjustment is completed, ensure that the gap between the punch 3 at the bottom of the upper plate 2 and the die 5 at the top of the lower plate 1 meets the processing requirements, start the stamping equipment, the upper plate 2 begins to descend, and the punch 3 gradually approaches the die 5. During the stamping process, the spring 18 at the bottom of the mounting base 17 and The guide rod 19 acts as a buffer and shock absorber, absorbing some of the impact force and protecting the mold and equipment from damage. When the punch 3 contacts the die 5 and applies pressure, the copper tube material undergoes plastic deformation under the action of the mold to form the required shape. After stamping, the elastic force of the spring 18 pushes the upper plate 2 to quickly return to its original position, preparing for the next stamping. At the same time, the sliding setting of the guide rod 19 in the guide rod seat 21 ensures the stable movement of the upper plate 2 in the vertical direction, avoiding poor stamping caused by offset or shaking. After stamping, the mold is opened, the processed copper tube is taken out, and the above process is repeated as needed for the next round of stamping.
