Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of differential housing processing, and more particularly to the technical field of differential housing punching, and specifically to a continuous differential housing processing punching equipment. BACKGROUND

[0002] The differential housing is an important component of the differential in the automobile transmission system, mainly used for containing and protecting the internal gear set (such as planetary gears, half shaft gears, etc.) of the differential, while connecting the transmission shaft and the half shaft to transmit power.

[0003] It is usually made of high-strength metal (such as cast iron or cast steel) to support, fix and seal, ensuring stable operation of the differential under complex working conditions. In order to meet the functional, economic and lightweight requirements in differential housing manufacturing, punching operation is needed for the differential housing.

[0004] For example, the patent with the authorization announcement number CN116603927B relates to a punching device for differential housing production. It is necessary to design a differential housing production punching device that can perform multi-angle punching to improve adaptability. A differential housing production punching device includes a fixed seat, a support plate, and a lifting plate, etc. The fixed seat left side middle part is fixedly connected with the support plate, and the support plate upper part is slidably connected with the lifting plate. The differential housing is placed on the rotating seat, the extension rod of the electric push rod is shortened to drive the lifting plate to move downward, so that the rubber plate contacts the inner side of the fixed seat to fix the rotating seat, the punching rod performs punching on the differential housing, and then the punching rod is separated from the differential housing. The servo motor is started to rotate, the rotating seat drives the differential housing to rotate to make the next position needing punching correspond to the punching rod. In this way, the rotating seat can perform multi-angle punching on the differential housing, thereby improving the adaptability.

[0005] For example, the patent with the authorization announcement number CN118926399B discloses a punching device for vehicle chassis, which includes a punching device shell, a hydraulic punch, and a vehicle chassis. The hydraulic punch is arranged at the top of the inner cavity of the punching device shell, and the vehicle chassis is arranged at the bottom of the inner cavity of the punching device shell. The outer wall of the punching device shell is provided with a turnover assembly for turning over the vehicle chassis. The bottom of the inner cavity of the punching device shell is provided with a positioning assembly for fixing the vehicle chassis. The bottom of the inner cavity of the punching device shell is provided with a cleaning assembly for cleaning the vehicle chassis. Through the arrangement of the turnover assembly, the threaded drive rod will drive the lifting platform to rise during rotation, and the lifting platform will drive the trigger rod to contact the top of the concave slide plate, thereby realizing the turnover of the vehicle chassis, and better controlling the angle and direction of the vehicle chassis during processing, improving the precision and accuracy of processing.

[0006] Combined with the actual performance in the differential housing punching equipment operation process, the current differential housing punching equipment still has certain disadvantages when used, such as:

[0007] 1. It needs to stop for loading operation, cannot continuously punch, and affects the punching operation efficiency;

[0008] 2. It cannot quickly position and eject the housing, and needs multiple operations to complete the discharging operation;

[0009] 3. Since the differential housing structure is a metal structure, it is not conducive to maintaining the vertical precision of the punch after multiple frequent punching operations, and it is not conducive to ensuring product quality.

[0050] In specific application scenarios, the front door 2 and rear door 3 set on the front and rear sides of the rack 1 can be opened for storage or placement of devices. The placement cabinet 4 is set inside the rack 1 for easy placement of items. At the same time, by starting the suction fan 6, the chip removal position of the punching can be connected through the connecting pipe 7 so that the chips can be sucked into the storage bin 5 by the suction fan 6 for chip collection, reducing chip splashing, avoiding affecting the punching accuracy, and avoiding safety accidents.

[0051] Among them: such as Figure 1 , Figure 2 , Figure 4 and Figure 5 In the middle, the fixed frame 10 is fixedly welded to the top center of the frame 1. The top of the fixed frame 10 is integrally fixed with a support frame 11. A slide table 12 is slidably installed on the inner top of the support frame 11. The bottom of the slide table 12 is provided with a limiting mechanism for maintaining the stable lifting and lowering of the stamping head 17. The top of the slide table 12 is connected to a first telescopic rod 13 whose end is fixed to the top of the support frame 11. The limiting mechanism includes a guide rod 15 symmetrically fixed to the bottom surface of the slide table 12 and a limiting frame 16 that can be lifted and slidably connected to the outside of the guide rod 15. The top center of the limiting frame 16 is fixedly connected to the bottom end of the stamping cylinder 14. The top of the stamping head 17 is installed in the middle of the limiting frame 16.

[0052] In specific application scenarios, by activating the first telescopic rod 13, the slide table 12 can be pushed and pulled on the top of the support frame 11 to adjust the front and rear positions of the slide table 12, thereby adjusting the front and rear positions of the punch head 17 for punching position adjustment. At the same time, a guide rod 15 is integrated vertically at the bottom of the slide table 12, which allows the limit frame 16 to slide stably on the outside of the guide rod 15. The bottom end of the punching cylinder 14 is fixedly connected to the middle of the limit frame 16, and the punch head 17 is fixed at the bottom of the middle of the limit frame 16. The punching cylinder 14 can stably raise and lower the punch head 17 to ensure stable punching operation and punching accuracy.

[0053] Among them: such as Figure 2 , Figure 4 and Figure 5In the middle, a receiving box 19 is provided on the inner side of the fixing frame 10. A handle 20 is installed at the end of the receiving box 19. The top surface of the receiving box 19 is in contact with the inner top surface of the fixing frame 10. The top of the receiving box 19 corresponds to the stamping groove 18 opened at the bottom of the support frame 11. A filter screen 21 is installed at the bottom rear side of the receiving box 19. An elastic pad 22 is provided below the filter screen 21. A clip head 23 is connected to the bottom of the elastic pad 22. The bottom of the receiving box 19 is engaged with the top of the connecting tube 7 through the clip head 23.

[0054] In specific application scenarios, the receiving box 19 is installed inside the fixing frame 10 by pulling it out. The top surface of the receiving box 19 can fit against the bottom surface of the inner side of the fixing frame 10, which facilitates the collection of waste generated during the punching process through the stamping groove 18 opened at the bottom of the support frame 11. At the same time, the bottom of the receiving box 19 is elastically connected to the clamp 23 through the elastic pad 22, which allows the receiving box 19 to be engaged with the top of the connecting tube 7 through the clamp 23, thereby limiting the position of the receiving box 19. The bottom of the receiving box 19 is provided with a filter screen 21, which can block larger waste particles, allowing fine debris particles to enter the interior of the storage bin 5 through the filter screen 21, so as to avoid debris splashing, avoid affecting the punching accuracy, and reduce the occurrence of safety accidents.

[0055] Among them: such as Figure 1 , Figure 6 , Figure 7 and Figure 8 In the middle, partitions 24 are symmetrically arranged on the top two sides of the frame 1. The inner side of the partition 24 is provided with a mounting plate 27 that can slide left and right. The top of the mounting plate 27 is provided with a stamping die 30 that can slide left and right and rotate for adjustment. The top of the stamping die 30 is provided with a cavity for placing the differential housing. The inner side of the partition 24 is fixedly installed with a slide rail 25. The inner side of the slide rail 25 is slidably connected with a slider 26. The slider 26 is fixedly installed at the bottom of the mounting plate 27. The middle part of the mounting plate 27 is fixedly installed with a drive motor 28. The output end of the drive motor 28 is connected to a connecting plate 29 that is rotatably arranged at the top of the mounting plate 27. The top of the connecting plate 29 is symmetrically fixedly installed with limit blocks 31. The bottom of the stamping die 30 is provided with a sliding groove 32 that engages with the limit block 31.

[0056] In specific application scenarios, the partition 24 is symmetrically arranged on the top surface of the frame 1. The slide rail 25 is fixedly installed on the inner side of the partition 24. The slider 26 can slide on the outer side of the slide rail 25 to adjust the position of the mounting plate 27, thereby allowing the stamping die 30 to slide left and right. At the same time, the start of the drive motor 28 can drive the connecting plate 29 to rotate, thereby adjusting the direction of the stamping die 30. Furthermore, the sliding structure at the bottom of the stamping die 30 above the limit block 31 facilitates the left and right sliding of the stamping die 30 above the connecting plate 29, allowing the stamping die 30 to carry the differential housing into the lower part of the stamping head 17 for punching operations.

[0057] Among them, such as Figure 6 , Figure 7 and Figure 9 In the middle, the inner bottom surface of the slide groove 32 is provided with gear teeth at equal intervals, the side of the stamping die 30 is provided with an installation groove 33, the top of the inner side of the installation groove 33 is provided with a slot 34, the installation groove 33 is provided with a translation gear 35 through the slot 34, the top of the translation gear 35 is meshed with the bottom of the slide groove 32, the bottom of the connecting plate 29 is provided with a slot 36, the inner side of the slot 36 is provided with a double-head motor 37, the output end of the double-head motor 37 is fixed with a drive gear 38, the drive gear 38 is meshed with the translation gear 35, the outer side of the double-head motor 37 is provided with a locking block 39, the bottom of the double-head motor 37 is provided with a pressure plate 40, the top of the pressure plate 40 is engaged with the locking block 39;

[0058] In specific application scenarios, the slot 36 at the bottom of the connecting plate 29 can engage the dual-head motor 37. The drive gear 38 fixed to the output end of the dual-head motor 37 drives the translation gear 35 to rotate. The translation gear 35 meshes with the gear teeth on the bottom surface of the slide groove 32 to drive the stamping die 30 to slide above the connecting plate 29. The top surface of the connecting plate 29 has an installation slot 33, and the top of the installation slot 33 has a top-opening slot 34, which can quickly assemble the translation gear 35. At the same time, the dual-head motor 37 is engaged inside the slot 36, which facilitates the installation of the dual-head motor 37. The engagement between the pressure plate 40 and the locking block 39 and the fixing between the pressure plate 40 and the connecting plate 29 facilitate the positioning and fixing of the dual-head motor 37.

[0059] Among them, such as Figure 8 and Figure 10In the process, the stamping die 30 is integrally equipped with a linkage mechanism for limiting and lifting the differential housing. The bottom surface of the stamping die 30 is symmetrically provided with a through groove 41. A limiting shell 42 is provided inside the through groove 41. The bottom of the limiting shell 42 is fixed to the stamping die 30 by a fixing foot 47. The linkage mechanism is installed inside the limiting shell 42. The linkage mechanism includes a pull rod 43 and a push rod 45 that form a linkage. The pull rod 43 is rotatably installed inside the limiting shell 42 on the outer side. The top of the pull rod 43 protrudes from the top of the limiting shell 42 and contacts the differential housing. The bottom end of the pull rod 43 is hinged to a connecting rod 44. The end of the connecting rod 44 is hinged to the bottom end of the push rod 45. The push rod 45 is rotatably installed inside the limiting shell 42 on the inner side. The top inner side of the push rod 45 is hinged to a second telescopic rod 46. The bottom end of the second telescopic rod 46 is hinged to the inner wall of the limiting shell 42.

[0060] In specific application scenarios, when loading the differential housing, a mechanical gripper places the differential housing onto the top of the stamping die 30. During placement, the position to be punched aligns with the punching hole 48. Simultaneously, the second telescopic rod 46 retracts, pulling the push rod 45 inwards to retract into the limiting housing 42. The bottom end of the push rod 45 is connected to the pull rod 43 via the connecting rod 44, causing the pull rod 43 to rotate synchronously. This allows the top end of the pull rod 43 to contact the differential housing, limiting its stability. The stamping die 30 slides to the left via the sliding between the slide rail 25 and the slider 26. The dual-head motor 37 drives the drive gear 38 to rotate, and the meshing between the drive gear 38 and the translation gear 35 drives the stamping die 30 to slide to the left, allowing it to enter the stamping cylinder 14. Below, the sliding table 12 slides back and forth to adjust the punching position. After the stamping die 30 is reset to the right, the connecting plate 29 is rotated by the drive motor 28 to adjust the direction of the differential housing and perform punching again. After punching, the extension of the second telescopic rod 46 pushes the top rod 45, thereby reversing the top of the top rod 45 out of the top of the limiting housing 42. At the same time, through the linkage between the top rod 45, the connecting rod 44 and the pull rod 43, the pull rod 43 is driven to rotate, so that the pull rod 43 is released from the limiting position of the differential housing, so that the differential housing can be lifted by the top rod 45, which facilitates the transfer of the differential housing. At the same time, two sets of stamping dies 30 are symmetrically arranged on the left and right sides of the support frame 11. After punching one set of differential housings, the other set of differential housings can be moved to the inside of the support frame 11 for punching, so as to continuously perform punching operations and improve the punching efficiency of the differential housing.
