Description

Technical Field

[0001] The invention relates to the technical field of differential case processing, and more particularly to the technical field of differential case punching, and in particular to a continuous punching device for differential case processing. Background Art

[0002] The differential housing is an important part of the differential in the automobile transmission system. It is mainly used to accommodate and protect the internal gear set of the differential (such as planetary gears, half-shaft gears, etc.), and at the same time connect the drive shaft and half-shaft to transmit power;

[0003] It is usually made of high-strength metal (such as cast iron or cast steel), and plays the role of supporting, fixing and sealing to ensure the stable operation of the differential under complex working conditions. In order to take into account the functionality, economy and lightweight requirements in the manufacture of the differential housing, the differential housing needs to be punched;

[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 punching device for differential housing production that can perform multi-angle punching and improve adaptability. A punching device for differential housing production includes a fixed seat, a support plate and a lifting plate, etc. The support plate is fixedly connected to the middle of the left side of the fixed seat, and the lifting plate is slidably connected to the upper part of the support plate. The present invention places the differential housing on the rotating seat, starts the telescopic rod of the electric push rod to shorten and 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, and the punching rod punches the differential housing again, and then the punching rod is disengaged from the differential housing, the servo motor is started to rotate, and the rotating seat drives the differential housing to rotate so that the next position that needs to be punched corresponds to the punching rod. In this way, the differential housing can be punched at multiple angles through the rotation of the rotating seat, thereby improving adaptability.

[0005] For another example, the patent with authorization announcement number CN118926399B discloses a punching device for a vehicle chassis, including a punching device shell, a hydraulic puncher, and a vehicle chassis. The hydraulic puncher 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 flipping assembly for flipping 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, and the bottom of the inner cavity of the punching device shell is provided with a cleaning assembly for cleaning the vehicle chassis. Through the setting of the flipping assembly, the threaded driving rod will drive the lifting platform to rise during the rotation of the threaded driving rod, and the rising of the lifting platform will drive the trigger rod to contact the top of the concave slide, thereby realizing the flipping of the vehicle chassis, thereby better controlling the angle and direction of the vehicle chassis during the processing, and improving the processing precision and accuracy.

[0006] Combined with the actual performance during the processing operation of the differential housing punching equipment, there are still certain drawbacks in the current differential housing punching equipment during use, such as:

[0007] 1. It is necessary to stop the machine for loading operations and cannot perform continuous punching operations, which affects the punching processing efficiency;

Among them, the bottom end of the stamping cylinder 14 is fixedly connected to the middle of the limiting frame 16, and the middle bottom end of the limiting frame 16 is fixed with a stamping head 17, which can stably lift the stamping head 17 through the stamping cylinder 14 for use to ensure stable punching operation and ensure punching accuracy.

[0053] Among them: As Figure 2 、 Figure 4 and Figure 5Inside, 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 attached to the inner top surface of the fixing frame 10. The top of the receiving box 19 corresponds to a punching groove 18 opened at the bottom of the support frame 11. A filter screen 21 is installed at the bottom of the rear side of the receiving box 19. An elastic pad 22 is provided below the filter screen 21. A chuck 23 is connected to the bottom of the elastic pad 22. The bottom of the receiving box 19 is snap-fitted to the top end of the connecting pipe 7 through the chuck 23;

[0054] In a specific application scenario, the receiving box 19 is installed on the inner side of the fixing frame 10 by a pulling method. The top surface of the receiving box 19 can be attached to the inner bottom surface of the fixing frame 10, which is convenient for collecting waste chips generated during the punching process through the punching 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 with a chuck 23 through an elastic pad 22, which can enable the receiving box 19 to be snap-fitted with the top end of the connecting pipe 7 through the chuck 23 to limit the position of the receiving box 19.

[0055] Among them: Such as Figure 1 , Figure 6 , Figure 7 and Figure 8 Inside, partition plates 24 are symmetrically arranged on both sides of the top of the machine frame 1. An installation plate 27 that can slide left and right is provided inside the partition plates 24. And a punching die 30 that can slide left and right and be rotationally adjusted is provided at the top of the installation plate 27. A mold cavity for placing the differential housing is opened at the top of the punching die 30. A slide rail 25 is fixedly installed inside the partition plates 24. A slider 26 is slidably connected to the inside of the slide rail 25. The slider 26 is fixedly installed at the bottom of the installation plate 27. A driving motor 28 is fixedly installed in the middle of the installation plate 27. The output end of the driving motor 28 is connected to a connecting plate 29 that is rotatably arranged at the top of the installation plate 27. Limiting blocks 31 are symmetrically and fixedly installed at the top of the connecting plate 29. A chute 32 corresponding to and engaging with the limiting blocks 31 is opened at the bottom of the punching die 30;

[0056] In a specific application scenario, through the symmetrical arrangement of the partition plate 24 on the top surface of the rack 1, and the slide rails 25 fixedly installed inside the partition plate 24, it is possible to slide the slider 26 outside the slide rails 25, so as to slide and adjust the position of the mounting plate 27, thereby sliding the stamping die 30 left and right. At the same time, by starting the driving motor 28, the driving motor 28 can drive the connecting plate 29 to rotate, so as to adjust the direction of the stamping die 30. And through the sliding structure of the bottom of the stamping die 30 above the limiting block 31, it is convenient for the stamping die 30 to slide left and right above the connecting plate 29, so that the stamping die 30 can carry the differential housing into the lower part of the punching head 17 for punching operations.

[0057] Among them, as Figure 6 , Figure 7 and Figure 9 show, the inner bottom surface of the chute 32 is provided with equally spaced teeth. An installation groove 33 is opened on the side of the stamping die 30, and a clamping groove 34 is opened at the top inside the installation groove 33. The installation groove 33 installs a translation gear 35 through the clamping groove 34. The top of the translation gear 35 meshes with the bottom of the chute 32 correspondingly. An opening groove 36 is opened at the bottom of the connecting plate 29, and a double-headed motor 37 is installed inside the opening groove 36. A driving gear 38 is fixed to the output end of the double-headed motor 37. The driving gear 38 is correspondingly meshed and connected with the translation gear 35. A clamping block 39 protrudes from the outside of the double-headed motor 37, and a pressing plate 40 is arranged at the bottom of the double-headed motor 37. The top of the pressing plate 40 is clamped with the clamping block 39;

[0058] In a specific application scenario, through the opening groove 36 opened at the bottom of the connecting plate 29, the double-headed motor 37 can be clamped. The driving gear 38 fixed to the output end of the double-headed motor 37 drives the translation gear 35 to rotate. Through the meshing of the translation gear 35 with the teeth on the bottom surface of the chute 32, it is convenient to drive the stamping die 30 to slide above the connecting plate 29. Among them, an installation groove 33 is opened on the top surface of the connecting plate 29, and a clamping groove 34 with an open top is opened at the top of the installation groove 33, which can quickly assemble the translation gear 35. At the same time, the double-headed motor 37 is clamped inside the opening groove 36, which is convenient for installing the double-headed motor 37. By using the clamping between the pressing plate 40 and the clamping block 39 and fixing the pressing plate 40 to the connecting plate 29, it is convenient to position and fix the double-headed motor 37.

[0059] Among them, as Figure 8 and Figure 10Among them, an interlocking mechanism for limiting and jacking up the differential housing is integrally and compoundly arranged inside the stamping die 30. Through grooves 41 are symmetrically formed in the bottom surface of the stamping die 30. A limiting outer shell 42 is arranged inside the through grooves 41. The bottom of the limiting outer shell 42 is fixed to the stamping die 30 through fixing feet 47. The interlocking mechanism is installed inside the limiting outer shell 42. The interlocking mechanism includes a pull rod 43 and a push rod 45 that form interlocking. The pull rod 43 is rotatably installed on the outer side inside the limiting outer shell 42. The top end of the pull rod 43 protrudes from the top of the limiting outer 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 on the inner side inside the limiting outer shell 42. The inner side of the top 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 side wall of the limiting outer shell 42;

[0060] In a specific application scenario, when loading the differential housing, the differential housing is correspondingly placed on the top of the stamping die 30 via a mechanical claw. When the differential housing is placed, the position to be punched is made to correspond to the punching hole 48. At the same time, the second telescopic rod 46 is retracted, so that the second telescopic rod 46 pulls the push rod 45, causing the push rod 45 to rotate inward and retract into the limiting outer shell 42. At the same time, the bottom end of the push rod 45 is connected to the pull rod 43 through the connecting rod 44, causing the pull rod 43 to rotate synchronously. Thus, the top end of the pull rod 43 rotates to contact the differential housing, and the differential housing is limited by the pull rod 43 to ensure the stable fixation of the differential housing. The stamping die 30 is slid to the left through the sliding between the slide rail 25 and the slider 26. The driving gear 38 is rotated by the double-headed motor 37. The stamping die 30 is driven to slide to the left by the meshing between the driving gear 38 and the translation gear 35, so that the stamping die 30 enters below the punching cylinder 14. Through the forward and backward sliding of the sliding table 12, the punching position can be adjusted. After the stamping die 30 is reset to the right, the direction of the differential housing can be adjusted by driving the connecting plate 29 to rotate by the driving motor 28, and punching processing is carried out again. After punching, by the elongation of the second telescopic rod 46, the second telescopic rod 46 pushes the push rod 45, so that the top end of the push rod 45 is reversed out of the top of the limiting outer shell 42. At the same time, through the interlocking between the push 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 disengaged from the limitation of the differential housing, so that the differential housing can be jacked up by the push rod 45, facilitating the transfer of the differential housing. At the same time, two groups of stamping dies 30 are symmetrically arranged on the left and right sides of the support frame 11, and after punching one group of differential housings is completed, the other group of differential housings can be moved to the inside of the support frame 11 for punching operations, facilitating continuous punching operations to improve the punching processing efficiency of the differential housing.
