Technical Field

[0001] This invention relates to the field of snap ring processing technology, specifically to a split-type high-stability auxiliary reset snap ring processing device. Background Technology

[0002] Currently available conventional brake pads use horseshoe-shaped retaining rings with auxiliary reset. To reliably achieve the auxiliary reset function, their spring auxiliary reset structure mostly adopts a transversely folded spring design, which is the mainstream structural form in the industry. As a key component in the brake pad assembly, the processing of this type of horseshoe-shaped retaining ring requires consideration of spring folding accuracy, overall structural symmetry, and dimensional consistency, placing high demands on the adaptability, stability, and precision of the production equipment.

[0003] Current specialized production equipment for this type of horseshoe-shaped retainer spring generally has many shortcomings, making it difficult to meet the demands for high-efficiency and high-precision production: First, the integration of processes is low, with core processes such as feeding, punching, and bending being scattered and poorly connected. Manual assistance is required for material transfer and positioning, which not only reduces production efficiency but also easily leads to deviations in processing benchmarks due to human intervention. Second, processing stability is insufficient; key processing steps such as punching and bending are prone to equipment vibration and positioning misalignment, making it difficult to meet the stringent requirements for the folding accuracy and overall dimensional accuracy of horseshoe-shaped retainer spring sheets, and thus failing to provide a reliable guarantee for the large-scale and standardized production of this type of retainer spring.

[0004] To address this, we propose a split-type high-stability auxiliary reset snap ring processing device. Summary of the Invention

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1 Please see Figures 1 to 9 As shown, a split-type high-stability auxiliary reset snap ring processing device includes a processing conveyor frame 1. Material conveying units 2 are located on both sides of the top of the processing conveyor frame 1, and a snap ring punching unit 3 is located in the middle of the top of the processing conveyor frame 1. The two material conveying units 2 continuously convey snap ring production materials, working in conjunction with the snap ring punching unit 3 to complete stable punching processing of the snap rings, forming continuous production processing of snap ring punched parts, thereby effectively improving the production efficiency of snap rings. A snap ring bending unit 4 is fixedly located on one side of the processing conveyor frame 1, and a snap ring discharge rack 5 is located on one side of the snap ring bending unit 4. After the snap ring parts are punched by the snap ring punching unit 3, the punched parts are transferred to the inside of the snap ring bending unit 4, where the snap ring bending unit 4 bends the snap ring punched parts to obtain bent snap ring formed parts. Finally, the bent parts are discharged from the inside of the snap ring discharge rack 5, realizing continuous feeding, punching, and bending output production of snap rings, significantly improving the production efficiency of snap rings.

[0022] Specifically, such as Figure 2 and Figure 3 As shown, the material conveying unit 2 includes conveying rubber rollers 11 symmetrically arranged on both sides of the top of the processing conveying frame 1. The top of the processing conveying frame 1 is provided with a material conveying channel 6, and several guide rollers are rotatably arranged inside the material conveying channel 6. The surfaces of these guide rollers extend 1-2 cm above the bottom of the inner wall of the material conveying channel 6, and each guide roller is covered with a silicone sleeve. The guide rollers convey the production material, preventing sliding wear caused by the material's movement within the material conveying channel 6, and improving the smoothness of the material's conveying. Conveying limiting linear slides 7 are fixedly arranged on both sides inside the material conveying channel 6, and conveying limiting plates 8 are slidably arranged on the front and rear sides of the top of the two conveying limiting linear slides 7. The two conveying limiting linear slides 7 are respectively located on both sides of the processing conveying frame 1. The conveying limiting linear slides 7 control the two conveying limiting plates 8 to limit the front and rear sides of the production material, preventing positional deviation during conveying and ensuring the accuracy of the material's position during the punching process.

[0023] Furthermore, in order to achieve automatic and continuous conveying of production materials, conveying adjustment servo cylinders 9 are fixedly installed on both sides of the top of the processing conveyor frame 1, and two conveying adjustment servo cylinders 9 are symmetrically arranged on both sides of the processing conveyor frame 1. A conveying mounting frame 10 is fixedly installed at the top of the drive shaft of the conveying adjustment servo cylinder 9, and the two symmetrical conveying mounting frames 10 are rotatably connected to the front and rear ends of the conveying rubber roller 11. A conveying servo motor 12 is fixedly installed on the back of the rear conveying mounting frame 10, and one end of the output shaft of the conveying servo motor 12 is fixedly connected to one end of the conveying rubber roller 11. The height of the conveying rubber roller 11 is adjusted by the drive end of the conveying adjustment servo cylinder 9 to adapt to the automatic and continuous conveying operation of production materials of different thicknesses. After the surface of the conveying rubber roller 11 contacts the surface of the production material, the output shaft of the conveying servo motor 12 controls the conveying rubber roller 11 to rotate counterclockwise, so that the conveying rubber roller 11 drives the production material to carry out automatic and continuous conveying operation inside the material conveying channel 6.

[0024] It should be noted that the aforementioned material conveying unit 2, through the symmetrically arranged conveying rubber rollers 11 on both sides of the top of the processing conveying frame 1, in conjunction with several guide rollers inside the material conveying channel 6, effectively avoids sliding wear of the production material during the conveying process, while improving the smoothness of the conveying and solving the problem of material wear and conveying jams that are easily caused by existing conveying structures; through the conveying limiting linear slides 7 fixed on both sides inside the material conveying channel 6, and the conveying limiting plates 8 slidably arranged on the front and rear sides of its top, precise conveying and limiting of the production material on the front and rear sides can be achieved, avoiding positional deviation during material conveying and ensuring the accurate positioning of subsequent punching processing. Compared to existing designs that lack effective limiting structures or have inconvenient limiting adjustments, this design offers superior positioning accuracy. Furthermore, the conveying adjustment servo cylinders 9 fixed on both sides of the top of the processing conveyor frame 1 can drive the conveying mounting frame 10 to adjust the height of the conveying rubber rollers 11, adapting to the conveying needs of production materials of different thicknesses. In conjunction with the conveying servo motor 12 on the back of the rear conveying mounting frame 10, which drives the conveying rubber rollers 11 to rotate, automatic and continuous conveying of production materials is achieved. This changes the current situation where some devices have poor thickness adaptability and require manual assistance in feeding, significantly improving conveying efficiency and automation, and laying the foundation for subsequent continuous punching processing.

[0025] Example 2 Specifically, such as Figure 4As shown, the snap ring blanking unit 3 includes a blanking lifting frame 14; lifting servo cylinders 13 are fixedly installed around the center of the processing conveyor frame 1, and the top of the drive shaft of the four lifting servo cylinders 13 is fixedly installed on the blanking lifting frame 14; a blanking servo cylinder 15 is fixedly installed on the top of the blanking lifting frame 14, and the bottom end of the drive shaft of the blanking servo cylinder 15 extends to the bottom of the blanking lifting frame 14, and a blanking mounting frame 16 is fixedly installed at the bottom end of the drive shaft of the blanking servo cylinder 15; connecting slide rods 22 are fixedly installed around the top of the blanking mounting frame 16, and the top ends of the four connecting slide rods 22 are slidably connected to the inside of the blanking lifting frame 14; the stability of the blanking mounting frame 16 during the blanking process is ensured by the four connecting slide rods 22.

[0026] Furthermore, a punching punch 17 is fixedly mounted on the bottom of the punching mounting frame 16 by bolts; a movable groove 18 is provided in the middle of the processing conveyor frame 1, and positioning frames 19 are fixedly mounted on both sides of the movable groove 18. A punching die 20 is provided inside the movable groove 18; the bottom sides of the punching die 20 are fixedly connected to the top of the two positioning frames 19 by bolts, the movable groove 18 is located directly below the punching mounting frame 16, and the punching punch 17 and the movable groove 18 are vertically aligned. When blanking production materials, blanking punches 17 and blanking dies 20 of different specifications and models are disassembled and assembled using bolts. The production material is passed through the top of the blanking die 20, and the blanking mounting frame 16 is moved downward by the drive end of the blanking servo cylinder 15. The production material is quickly blanked by the cooperation between the blanking punch 17 and the blanking die 20. The production material is continuously conveyed at a fixed distance on the top of the blanking die 20 by the conveying rubber rollers 11 on both sides. The blanking mounting frame 16 is continuously blanked by the drive end of the blanking servo cylinder 15, so as to realize the continuous blanking processing of the snap ring blanking parts.

[0027] It should be noted that the lifting servo cylinder 13, which is fixed around the center of the processing conveyor frame 1, can drive the blanking lifting frame 14 to lift as a whole, making it easy to adjust the blanking height according to processing requirements and improving the operational flexibility of the device. The blanking servo cylinder 15, which is fixed at the top of the blanking lifting frame 14, has its drive shaft connected to the blanking mounting frame 16 at the bottom. The connecting slide rod 22, which is fixed around the top of the blanking mounting frame 16, is slidably connected to the inside of the blanking lifting frame 14, effectively ensuring the stability of the blanking mounting frame 16 during the blanking process. This avoids the problem of insufficient blanking accuracy caused by the shaking of the mounting frame during the blanking process. Compared with the poor stability of existing blanking structures, the blanking quality is easier to control. The blanking punch 17 is fixed at the bottom of the blanking mounting frame 16 by bolts. The blanking die 20 is fixed to the positioning frame 19 in the movable groove 18 in the middle section by bolts. The bolt connection method facilitates quick disassembly and replacement of blanking punches 17 and blanking dies 20 of different specifications and models, which can adapt to the blanking needs of different specifications of retaining springs. This solves the problem of fixed mold system and poor adaptability of some existing blanking devices. At the same time, the blanking die 20 and the blanking punch 17 are vertically aligned. With the help of the conveying rubber rollers 11 of the material conveying units 2 on both sides, the production material is continuously conveyed at a fixed distance on the top of the blanking die 20. The blanking servo electric cylinder 15 drives the blanking mounting frame 16 to perform continuous blanking, realizing the continuous blanking processing of retaining spring blanking parts. This changes the inefficient mode of some existing devices that require single feeding and single blanking, greatly improves the blanking processing efficiency, and has better blanking accuracy and consistency.

[0028] Example 3 Specifically, such as Figures 5 to 9 As shown, the snap ring bending unit 4 includes a connecting fixing frame 25 fixedly installed in the middle of one side of the processing conveyor frame 1, and one side of the movable groove 18 extends into the interior of the connecting fixing frame 25; a bending processing frame 23 is fixedly installed inside the connecting fixing frame 25, and mold changing frames 24 are fixedly installed on both sides of the connecting fixing frame 25, and the interiors of the two mold changing frames 24 are connected to the interiors of the bending processing frame 23; mold changing servo linear slides 32 are fixedly installed on both sides of the inner wall of the bending processing frame 23, and the two ends of the two mold changing servo linear slides 32 extend into the interiors of the two mold changing frames 24 respectively; two lower mold mounting frames 33 are slidably installed between the two mold changing servo linear slides 32, and the tops of the two lower mold mounting frames 33 are fixedly installed with lower mold frames 34 by bolts; wherein, the tops of the two lower mold frames 34 are provided with different bending cavities.

[0029] Furthermore, two shifting servo linear slides 28 are fixedly installed at the bottom of the inner wall of the movable groove 18, and loading and unloading servo cylinders 29 are slidably installed on the top of the two shifting servo linear slides 28. Loading and unloading servo cylinders 29 are fixedly installed at the top of the drive shaft of the loading and unloading servo cylinders 29, and an electromagnetic adsorption frame 31 is also fixedly installed on the top of the loading and unloading frame 30. The top of the electromagnetic adsorption frame 31 is used to magnetically adsorb the blanking and bending parts of the reset snap ring 27, thereby cooperating with the shifting servo linear slides 28 and the loading and unloading servo cylinders 29 to complete the transfer operation of the blanking and bending parts of the reset snap ring 27. When processing the blanking part of the reset snap ring 27, the loading and unloading frame 30 is controlled to be located at the bottom of the blanking die 20, and the electromagnetic adsorption frame 31 is used to adsorb the blanking part of the reset snap ring 27 to ensure the adsorption and positioning accuracy of the blanking part of the reset snap ring 27.

[0030] Furthermore, bending servo cylinders 26 are fixedly installed around the top of the bending processing frame 23, and an upper die frame 35 is movably installed at the bottom of the bending processing frame 23. The top of the upper die frame 35 is fixedly connected to the bottom of the drive shafts of the four bending servo cylinders 26. Several telescopic bending blocks 36 are movably installed at the bottom of the upper die frame 35, and telescopic positioning blocks 37 are also movably installed at the bottom of the upper die frame 35. Telescopic servo control cylinders 38 are fixedly installed inside the upper die frame 35 and on top of the several telescopic bending blocks 36 and the telescopic positioning blocks 37. The bottom end of the drive shaft is fixedly connected to the top of several telescopic bending blocks 36 and telescopic positioning blocks 37 respectively; among them, several telescopic bending blocks 36, telescopic positioning blocks 37 and the bottom of the upper mold frame 35 are all integrated with electromagnetic blocks. During the feeding operation of the blanking part of the reset snap ring 27, the loading and unloading frame 30 is controlled to move upward by the drive end of the loading and unloading servo cylinder 29, transferring the blanking part of the reset snap ring 27 adsorbed on the top of the electromagnetic adsorption frame 31 to the bottom of the upper mold frame 35, and using the electromagnetic blocks integrated at the bottom of the upper mold frame 35 to adsorb and position the blanking part of the reset snap ring 27; then The loading and unloading racks 30 are reset, and the lower die mounting bracket 33 inside the die changing frame 24 is slid to directly below the upper die frame 35. The upper die frame 35, in conjunction with different lower die frames 34, is used to bend and form the punched part of the reset spring 27. During the bending process of the punched part of the reset spring 27, the telescopic positioning block 37 is used to fix the center position of the punched part of the reset spring 27 to ensure the bending accuracy and prevent positional shift during bending. Finally, the formed part of the reset spring 27 inside the lower die frame 34 is... The reset snap ring 27 is removed by magnetic adsorption. The molded part of the snap ring 27 is sent out from the inside of the snap ring ejector 5 by the shifting servo linear slide 28, the loading and unloading rack 30 and the electromagnetic adsorption rack 31. One side of the snap ring ejector 5 is fixedly connected to one side of the connecting fixing frame 25. One side of the shifting servo linear slide 28 passes through the connecting fixing frame 25 and extends into the inside of the snap ring ejector 5. The top of the snap ring ejector 5 is provided with an ejector cover plate that rotates via a hinge. When the reset snap ring 27 is being processed, the reset snap ring 27 is taken out by a robotic arm by opening the ejector cover plate on the top of the snap ring ejector 5.

[0031] It should be noted that the aforementioned snap ring bending unit 4 is connected to the processing conveyor frame 1 via the connecting fixing frame 25. The movable groove 18 extends into the interior of the connecting fixing frame 25, achieving seamless connection between the punching and bending processes, reducing the distance and time for material transfer between processes. The die-changing servo linear slides 32 fixed on both sides of the inner wall of the bending processing frame 23 extend into the interior of the two die-changing frames 24, and two lower die mounting frames 33 are slidably arranged between the two die-changing servo linear slides 32. The top of the lower die mounting frame 33 is fixed with a lower die frame 34 with different bending cavities by bolts, which can be changed by die-changing. The servo linear slide 32 drives the lower die mounting bracket 33 to slide, quickly switching between lower die brackets 34 for different bending cavities, adapting to the processing of snap rings with different bending requirements. Compared with the existing bending devices, which have cumbersome die changing and limited adaptability, the die changing efficiency and adaptability are greatly improved. Two shifting servo linear slides 28 are fixed at the bottom of the inner wall of the movable groove 18, and loading and unloading servo cylinders 29 are slidably installed on their tops. The loading and unloading servo cylinders 29 drive the loading and unloading frame 30 to rise and fall. The electromagnetic adsorption frame 31 on the top of the loading and unloading frame 30 can accurately adsorb the punched parts and bent parts, working in conjunction with the shifting servo linear slides 22. 8. Automatic material transfer between punching, bending, and unloading processes is achieved, solving the problems of manual loading and unloading required in some existing devices, low transfer efficiency, and easy material damage or positioning deviation. The bending servo electric cylinder 26 at the top of the bending processing frame 23 drives the upper die frame 35 to rise and fall. The telescopic bending block 36 and telescopic positioning block 37 at the bottom of the upper die frame 35 are driven to extend and retract by an internal telescopic servo control electric cylinder 38. The telescopic positioning block 37 can precisely fix the center position of the circlip punched part, avoiding positional deviation during bending and improving bending processing accuracy. The bending block 36 can adapt to the processing requirements of different bending shapes. Compared with the existing bending structure, which has poor positioning effect and limited adaptability to bending shapes, the processing flexibility and accuracy are significantly improved. In addition, the snap ring ejector 5 is fixedly connected to the connecting fixing frame 25, and the shifting servo linear slide 28 extends into the snap ring ejector 5. Together with the electromagnetic adsorption frame 31, it realizes the automatic feeding of the formed snap ring. The design of the ejector cover plate facilitates the robotic arm to pick up the material, further improving the automated continuous operation process, greatly improving the overall production efficiency, and ensuring the orderliness and convenience of the ejection process.

[0032] Example 4 Specifically, this embodiment also discloses a working method for a split-type high-stability auxiliary reset snap ring processing device, as follows: First, the processing conveyor frame 1 serves as the overall installation base. The material conveying units 2 on both sides of its top start operation. The conveying adjustment servo cylinder 9 drives the conveying mounting frame 10 to rise and fall according to the thickness of the production material, thereby adjusting the height of the conveying rubber roller 11 so that the surface of the conveying rubber roller 11 is in close contact with the material. Then, the conveying servo motor 12 on the back of the rear conveying mounting frame 10 starts, driving the conveying rubber roller 11 to rotate counterclockwise. At the same time, several guide rollers inside the material conveying channel 6 play an auxiliary guiding role for the material, avoiding sliding wear during the material conveying process. The conveying limit linear slides 7 on both sides of the material conveying channel 6 drive the conveying limit plates 8 to slide in the front and back direction, accurately limiting the front and back sides of the material to prevent positional deviation during material conveying, ensuring that the material is stably and continuously conveyed to the snap ring punching unit 3 at the top center of the processing conveyor frame 1. When the material is conveyed to the blanking die 20 above the circlip blanking unit 3, the lifting servo cylinder 13 around the center of the processing conveyor frame 1 first drives the blanking lifting frame 14 to adjust to the appropriate blanking height. Then, the blanking servo cylinder 15 at the top of the blanking lifting frame 14 is activated, and its drive shaft drives the blanking mounting frame 16 to move downward. The connecting slide rod 22 around the top of the blanking mounting frame 16 slides along the inside of the blanking lifting frame 14 to ensure the stability of the blanking mounting frame 16 during the downward movement. This drives the blanking punch 17 at the bottom of the blanking mounting frame 16, which is fixed by bolts, to move downward synchronously. It cooperates with the blanking die 20 fixed on the positioning frame 19 on both sides of the movable groove 18 to accurately blank the material. At the same time, the conveying rubber rollers 11 of the material conveying units 2 on both sides drive the material to be conveyed continuously at a fixed distance, so that the circlip blanking unit 3 can realize the continuous blanking operation of the circlip blanking parts. After blanking is completed, the two shifting servo linear slides 28 at the bottom of the inner wall of the movable groove 18 are activated, driving the loading and unloading servo cylinders 29 slidably connected at their top to move to below the blanking die 20. The loading and unloading servo cylinders 29 drive the loading and unloading rack 30 to move upward, so that the electromagnetic adsorption rack 31 at the top of the loading and unloading rack 30 contacts the blanking part and generates magnetic adsorption, realizing the precise picking of the blanking part. Then, the shifting servo linear slides 28 drive the loading and unloading servo cylinders 29 and the adsorbed blanking part to the snap ring bending unit 4. The snap ring bending unit 4 is fixedly connected to the processing conveyor frame 1 through the connecting fixing frame 25, and the movable groove 18 extends into the interior of the connecting fixing frame 25, realizing the seamless connection between the blanking and bending processes, reducing the distance and time of material transfer between processes. At this time, the loading and unloading servo cylinders 29 drive the loading and unloading rack 30 to rise, transferring the blanking part to the bottom of the upper die frame 35. The electromagnetic block integrated at the bottom of the upper die frame 35 is used to adsorb and position the blanking part, and then the bending processing rack 23... The mold-changing servo linear slides 32 on both sides of the inner wall are activated, with their ends extending into the mold-changing frames 24 on both sides. They drive the two lower mold mounting frames 33 to slide along the mold-changing servo linear slides 32, moving the lower mold frame 34 with the adaptable bending cavity at the top to directly below the upper mold frame 35. If it is necessary to adapt to the processing of snap rings with different bending requirements, the mold-changing servo linear slides 32 can quickly switch the lower mold frames 34 with different bending cavities, greatly improving the mold-changing efficiency and adaptability. Then, the bending servo electric cylinders 26 around the top of the bending processing frame 23 are activated, and their drive shafts drive the upper mold frame 35 to move downward. At the same time, the telescopic servo control electric cylinders 38 inside the upper mold frame 35 drive the telescopic positioning blocks 37 to extend downward, accurately fixing the center position of the punched part, avoiding positional deviation during the bending process, and ensuring the bending processing accuracy. After that, the telescopic servo control electric cylinders 38 drive several telescopic bending blocks 36 to extend downward, cooperating with the bending cavity of the lower mold frame 34 to perform precise bending processing on the punched part. After the bending process is completed, the telescopic bending block 36 and the telescopic positioning block 37 are reset under the action of the telescopic servo control electric cylinder 38. The electromagnetic block at the bottom of the upper mold frame 35 is released from adsorption, and the electromagnetic adsorption frame 31 at the top of the loading and unloading frame 30 adsorbs the formed snap ring part again. The shifting servo linear slide 28 drives the loading and unloading servo electric cylinder 29 and the formed snap ring part to move into the snap ring ejector frame 5. One side of the snap ring ejector frame 5 is fixedly connected to the connecting fixing frame 25, and one side of the shifting servo linear slide 28 extends through the connecting fixing frame 25 into the snap ring ejector frame 5. Finally, the ejector cover plate at the top of the snap ring ejector frame 5 is opened and rotated by the hinge. The formed snap ring part is taken out by the robotic arm, completing the continuous processing flow of the entire snap ring.
