Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a stamping device for processing clutch diaphragm springs. Background Technology

[0002] The clutch diaphragm spring is a core elastic component in the automotive transmission system. Its quality directly determines the smoothness of clutch engagement and service life. Diaphragm springs usually require multiple processes such as blanking, multi-pass forming, punching and grooving, heat treatment and surface treatment. Among them, punching the center hole and release finger groove on the formed diaphragm spring is a crucial precision machining process. Traditional stamping equipment lacks a conveying mechanism during processing. When feeding materials, workers often have to manually place and judge the position, which can easily lead to deviations in the position of the raw materials, resulting in poor product processing and increased scrap rate. At the same time, in some manually fed stamping dies, due to the lack of a precise positioning device, the position of the diaphragm spring blank in the die is deviated, which makes it difficult to guarantee the dimensional accuracy of the stamped products and affects production efficiency. Summary of the Invention

[0003] To solve the above technical problems, the present invention is achieved through the following technical solution: a stamping device for processing clutch diaphragm springs, comprising a machine body, a stamping mechanism mounted on the top of the machine body, a drive box fixedly mounted on the outer surface of the machine body, a conveying mechanism mounted on the top of the drive box, the conveying mechanism conveying the workpiece to be processed to the stamping position, and lower die parts mounted on the upper surface of the conveying mechanism, the number of lower die parts being eight, and the eight lower die parts being evenly distributed along the axis of the conveying mechanism; The conveying mechanism includes a motor, which is fixedly mounted on the top of the drive box cavity via a bracket. The output end of the motor is fixedly connected to a drive shaft, which passes through the drive box and extends to its top. A support tray is fixedly mounted on the top of the drive shaft, and a working disc is fixedly mounted on the top of the support tray. A material passage hole is opened at the edge of the outer surface of the working disc, and the lower die is positioned directly above the material passage hole. The motor drives the drive shaft to rotate the support tray, and the working disc on top of the support tray rotates accordingly. The working disc rotates intermittently, sequentially delivering each station to the area directly below the stamping mechanism.

[0004] Preferably, a feed inlet is provided on the surface of the machine body, the feed end of the feed inlet is located directly below the stamping mechanism, and a discharge gate is provided at the discharge end of the feed inlet. The discharge gate is rotatably installed on the side of the machine body. After the workpiece is stamped, the waste material is discharged through the feed inlet. The discharge gate is used to periodically clean the waste material collected inside the machine body.

[0005] Preferably, when the working disc rotates around the drive shaft, the material passage hole can coincide with the feed inlet. After the workpiece is stamped at this station, the waste material falls into the feed inlet on the machine body through the material passage hole. The surface of the working disc is provided with mounting holes and fine-tuning grooves. The mounting holes and fine-tuning grooves are arranged opposite to each other on both sides of the material passage hole. The mounting holes and fine-tuning grooves are used to install the lower die and allow the position of the lower die to be finely adjusted to ensure accurate alignment with the upper die.

[0006] Preferably, the lower mold includes a lower module, on which the diaphragm spring to be processed is directly placed. A rotating shaft and a fine-tuning block are installed opposite each other on both sides of the bottom of the lower module. The rotating shaft is rotatably installed inside the mounting hole, and the fine-tuning block is slidably installed inside the fine-tuning groove. A return spring is fixedly connected between the two sides of the fine-tuning block and the inner wall of the fine-tuning groove. If the lower module and the upper mold are not fully aligned due to error during stamping, the upper mold will squeeze the upper mold to make it rotate around the rotating shaft, and the deformation of the return spring provides buffering.

[0007] Preferably, the stamping mechanism includes a hydraulic cylinder, which is fixedly installed on the top of the machine body. A hydraulic rod is fixedly connected to the telescopic end of the hydraulic cylinder, and a slider is fixedly installed at the bottom of the hydraulic rod. Guide posts are fixedly connected between the four corners of the top of the slider and the inner side of the machine body. An upper die is installed at the middle of the bottom of the slider, and the upper die is positioned directly above the feed inlet. The hydraulic cylinder drives the slider to slide up and down along the guide posts to ensure that the upper die can accurately punch the workpiece. The guide posts ensure that the slider maintains a precise vertical direction during its up and down movement, preventing the upper die from shifting during stamping.

[0008] Preferably, the upper mold includes an upper module, an annular sleeve is fixedly mounted on the outer surface of the upper module, and a compression ring is slidably mounted on the bottom of the annular sleeve.

[0009] Preferably, a buffer spring is fixedly connected between the top of the extrusion ring and the inner wall of the annular sleeve. The extrusion ring is extruded and adapted to the top of the lower module. Before the stamping begins, the extrusion ring extrudes the lower module, and the buffer spring is compressed. If there is a deviation between the upper module and the lower module, the extrusion ring pushes the lower module to rotate for fine adjustment of position.

[0010] This utility model provides a stamping device for processing clutch diaphragm springs. It has the following beneficial effects: (i) The stamping device for processing clutch diaphragm springs, through the setting of the conveying mechanism, the motor drives the transmission shaft to drive the work plate to rotate intermittently. The eight lower die parts evenly distributed on the work plate are sent to the bottom of the stamping mechanism in sequence and accurately. While stamping at one station, the worker can load materials at other empty stations, reducing the need for manual positioning. The rotation of the conveying mechanism ensures that the workpiece is in the same precise position each time it is stamped, ensuring product consistency.

[0011] (ii) The stamping device used for processing clutch diaphragm springs, through the setting of the lower die, when the stamping starts, the extrusion ring first contacts the workpiece and presses down. If there is a slight deviation between the upper and lower dies, the extrusion ring will generate a lateral thrust on the lower die, and the lower die will rotate slightly around the rotating shaft. The fine adjustment block slides in the fine adjustment groove, and the reset spring deforms accordingly until the upper and lower dies are accurately aligned, avoiding die chipping or workpiece tearing and deformation caused by hard misalignment, thus improving the product qualification rate.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-7This utility model provides a technical solution: a stamping device for processing clutch diaphragm springs, including a machine body 1, a stamping mechanism 2 installed on the top of the machine body 1, a drive box 3 fixedly installed on the outer surface of the machine body 1, a conveying mechanism 4 installed on the top of the drive box 3, the conveying mechanism 4 conveys the workpiece to be processed to the stamping position, and a lower die 5 is installed on the upper surface of the conveying mechanism 4. The number of lower die 5 is eight, and the eight lower die 5 are evenly distributed along the axis of the conveying mechanism 4. The conveying mechanism 4 includes a motor 41, which is fixedly installed on the top of the inner cavity of the drive box 3 by a bracket. The output end of the motor 41 is fixedly connected to a drive shaft 42, which passes through the drive box 3 and extends to its top. A support tray 43 is fixedly installed on the top of the drive shaft 42, and a working disc 44 is fixedly installed on the top of the support tray 43. A material passage hole 45 is opened at the edge of the outer surface of the working disc 44. The lower die 5 is located directly above the material passage hole 45. The motor 41 drives the drive shaft 42 to rotate the support tray 43, and the working disc 44 on the top of the support tray 43 rotates accordingly. The working disc 44 rotates intermittently, sending each station to the bottom of the stamping mechanism 2 in sequence. A feed inlet 6 is provided on the surface of the machine body 1. The feed end of the feed inlet 6 is located directly below the stamping mechanism 2. A discharge gate 7 is provided at the discharge end of the feed inlet 6. The discharge gate 7 is rotatably installed on the side of the machine body 1. After the workpiece is stamped, the waste is discharged through the feed inlet 6. The discharge gate 7 is used to periodically clean the waste collected in the machine body 1. When the worktable 44 rotates around the drive shaft 42, the material passage hole 45 can coincide with the feed port 6. After the workpiece is stamped at this station, the waste material falls into the feed port 6 on the machine body 1 through the material passage hole 45. The surface of the worktable 44 is provided with mounting holes 46 and fine adjustment grooves 47. The mounting holes 46 and fine adjustment grooves 47 are opposite to each other on both sides of the material passage hole 45. The mounting holes 46 and fine adjustment grooves 47 are used to install the lower die 5 and allow the position of the lower die 5 to be finely adjusted to ensure accurate alignment with the upper die 25. The lower mold 5 includes a lower module 51, on which the diaphragm spring to be processed is directly placed. A rotating shaft 52 and a fine-tuning block 53 are mounted opposite each other on the bottom two sides of the lower module 51. The rotating shaft 52 is rotatably installed inside the mounting hole 46, and the fine-tuning block 53 is slidably installed inside the fine-tuning groove 47. A return spring 54 is fixedly connected between the two sides of the fine-tuning block 53 and the inner wall of the fine-tuning groove 47. If the lower module 51 and the upper mold 25 are not fully aligned due to error during stamping, the upper mold 25 will squeeze the upper mold 25 to make it rotate around the rotating shaft 52, and the deformation of the return spring 54 provides buffering.

[0016] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figure 3-7As shown, the stamping mechanism 2 includes a hydraulic cylinder 21, which is fixedly installed on the top of the machine body 1. A hydraulic rod 22 is fixedly connected to the telescopic end of the hydraulic cylinder 21. A slider 23 is fixedly installed at the bottom of the hydraulic rod 22. Guide posts 24 are fixedly connected between the four corners of the top of the slider 23 and the inner side of the machine body 1. An upper die 25 is installed at the middle of the bottom of the slider 23. The upper die 25 is located directly above the feed port 6. The hydraulic cylinder 21 drives the slider 23 to slide up and down along the guide post 24 to ensure that the upper die 25 can accurately punch the workpiece. The guide post 24 ensures that the slider 23 maintains a precise vertical direction during the up and down movement, preventing the upper die 25 from deviating during stamping. The upper module 25 includes an upper module 251, an annular sleeve 252 is fixedly installed on the outer surface of the upper module 251, and an extrusion ring 253 is slidably installed on the bottom of the annular sleeve 252. A buffer spring 254 is fixedly connected between the top of the extrusion ring 253 and the inner wall of the annular sleeve 252. The extrusion ring 253 is extruded and adapted to the top of the lower module 51. Before the stamping starts, the extrusion ring 253 extrudes the lower module 51 and the buffer spring 254 is compressed. If there is a deviation between the upper module 251 and the lower module 51, the extrusion ring 253 pushes the lower module 51 to rotate for fine adjustment of position.

[0017] When in use, the operator places the clutch diaphragm spring blank to be processed into the positioning slot of the lower module 51. The motor 41 starts and drives the bearing tray 43 and the working plate 44 to start rotating through the transmission shaft 42. The motor 41 drives the working plate 44 to rotate intermittently. When the rotation stops, the loaded station is accurately delivered to the bottom of the stamping mechanism 2. The hydraulic cylinder 21 drives the hydraulic rod 22 to push the slider 23 to slide smoothly and vertically downward along the guide post 24. The extrusion ring 253 at the bottom of the upper mold 25 first contacts the workpiece on the lower module 51. The slider 23 continues to move downward, the buffer spring 254 is compressed, and the extrusion ring 253 generates a uniform pressure, firmly pressing the workpiece onto the lower module 51. If there is a slight coaxiality deviation between the upper module 251 and the lower module 51, the inclined surface of the extrusion ring 253 will generate a lateral thrust on the edge of the lower module 51, causing the lower module 51 to rotate around the rotation axis 52 at a slight angle. At the same time, the fine-tuning block 53 slides in the fine-tuning groove 47, and the return spring 54 deforms accordingly until the dies of the upper module 251 and the lower module 51 are completely aligned. As the slider 23 continues to descend, the punch inside the upper module 251 passes through the center hole of the extrusion ring 253 and begins to contact the workpiece. The hydraulic pressure causes the punch to penetrate the workpiece, completing the punching of the center hole and the slot. The resulting waste is punched into the center hole of the lower module 51. The waste generated by punching falls into the feed port 6 on the machine body 1 through the material passage hole 45 on the working plate 44. The waste slides along the feed port 6 into the collection area inside the machine body 1. After the stamping is completed, the hydraulic cylinder 21 begins to retract, and the slider 23 returns to its highest point, waiting for the next cycle.
