[0002] Automotive shock absorber bushings are core shock absorber connecting components on automotive chassis suspension, control arms, tie rods, and stabilizer bars. They consist of metal sleeves inside and out, with an elastomer such as rubber or polyurethane wrapped in the middle. They are used to connect chassis components, providing both rigid support and filtering vibrations. Automotive shock absorber bushings are manufactured using stamping dies, resulting in high-precision cold-forged drum-shaped shock absorber bushings with more accurate dimensions.

[0021] A fixing plate 9 is installed on one side of the base 1. Two sets of symmetrically distributed fixing cylinders 10 are provided on the side of the fixing plate 9 away from the conveying plate 7, and countersunk holes 25 are opened inside the two sets of fixing cylinders 10. The conveying plate 7 is provided with two sets of connecting rods 26 on one side wall corresponding to the fixed cylinder 10. The other end of the two sets of connecting rods 26 passes through the fixed plate 9 and is inserted into the interior of the corresponding countersunk hole 25.

[0022] A third return spring 30 is provided between the end of the connecting rod 26 and the inner end face of the countersunk hole 25, and the connecting rod 26 is elastically inserted into the countersunk hole 25 through the third return spring 30; The inner wall of the countersunk hole 25 is provided with a sliding groove 27, and the connecting rod 26 is provided with a slider 28 at the position corresponding to the sliding groove 27, which can slide inside the sliding groove 27.

[0023] A driving block 12 is provided at the lower end of the mounting plate 2 corresponding to the position of the stamping plate 11. A first storage groove 13 is provided at the lower end of the driving block 12. A first push plate 15 is slidably provided inside the first storage groove 13, and a first reset spring 141 is provided between the end face of the first push plate 15 and the top end of the first storage groove 13. An air-storing airbag 14 is provided between the end face of the first push plate 15 and the inner top of the first storage groove 13. A fifth exhaust pipe 29 is provided between the end of the connecting rod 26 and the inner top of the countersunk hole 25; A connecting pipe 23 is installed on the side wall of the base 1 at the position corresponding to the fixed cylinder 10.

The top of the air storage bag 14 is provided with a first exhaust pipe 22, and the other end of the first exhaust pipe 22 passes through the mounting plate 2 and the support rod 5 in sequence and is connected to the corresponding second exhaust pipe 24.

[0024] The lower end of the drive block 12 is provided with a second storage groove 16, and a second push plate 18 is slidably disposed inside the second storage groove 16. The upper end of the stamping plate 11 is provided with a top plate 17 corresponding to the position of the second push plate 18. A second return spring 19 is provided between the upper end of the second push plate 18 and the inner top of the second storage groove 16; A through hole 21 is provided between the second storage slot 16 and the first storage slot 13. A pull rope 20 is provided inside the through hole 21. The two ends of the pull rope 20 are respectively connected to the upper end of the second push plate 18 and the upper end of the first push plate 15.

[0025] In the above technical solution: The telescopic cylinder 4 is activated, causing the stamping plate 11 to move downwards. During the downward movement of the stamping plate 11, the top plate 17 gradually stops being inserted into the second receiving slot 16. At this time, the second push plate 18 is no longer held in place, and under the action of the second return spring 19, it is pushed downwards. The pull rope 20 connected to the second push plate 18 will then pull the first push plate 15 upwards, thereby compressing the air storage bag 14 through the first push plate 15. The gas inside the air storage bag 14 is discharged into the fifth exhaust pipe 29 through the first exhaust pipe 22. The fifth exhaust pipe 29 expands, pushing the connecting rod 26 to move, and... The conveyor plate 7 moves downward toward the stamping plate 11, automatically transporting the automotive shock absorber bushing to be stamped to the stamping station. After the stamping operation is completed, the telescopic cylinder 4 moves the stamping plate 11 upward and resets it. The top plate 17 is re-inserted into the second storage slot 16 and pushes the second push plate 18 upward. The second push plate 18 releases the pull on the first push plate 15 through the pull rope 20, the air storage bag 14 is no longer squeezed, the gas flows back, the air pressure in the fifth exhaust pipe 29 decreases, the third reset spring 30 pushes the connecting rod 26 to move in the opposite direction, and the conveyor plate 7 automatically exits from the stamping station. The bushing after stamping can be directly unloaded manually.

[0026] Example 3: Figures 7-10 As shown, the automotive shock absorber bushing processing device disclosed in Embodiment 3 of the present invention has a structure that is basically the same as that in Embodiment 2, except that: The bottom of the material cylinder 6 is provided with a fourth storage groove 41 on both sides. A second clamping plate 36 is inserted into the interior of each fourth storage groove 41, and a fourth return spring 42 is provided between the end of the second clamping plate 36 and the inner side wall of the fourth storage groove 41. The inner sidewall of the fourth storage slot 41 is provided with a guide slot 43, and the sidewall of the second clamping plate 36 is provided with a guide block 44 that can slide inside the guide slot 43 at the position corresponding to the fourth reset spring 42. A sixth air-storing bladder 45 is provided between the side wall of the guide block 44 and the inner end face of the guide groove 43.

[0027] The lower end of the material cylinder 6 is provided with a third storage groove 37 corresponding to the position of the conveying plate 7. A top holding rod 38 is inserted into the interior of the third storage groove 37, and a fifth air storage bag 39 is provided between the upper end of the top holding rod 38 and the top of the interior of the third storage groove 37. A fourth exhaust pipe 40 is provided between the fifth air storage bag 39 and the sixth air storage bag 45; A third air-storing bladder 33 is provided at the upper end of the conveying plate 7 at the position corresponding to the top support rod 38.

[0028] A groove is provided at the center of the upper surface of the conveying plate 7, and an extrusion plate 31 is provided inside the groove. A fourth air storage bag 35 is provided between the lower end of the extrusion plate 31 and the bottom of the groove. The upper surface of the conveying plate 7 is provided with relief grooves 32 on both sides corresponding to the fourth air storage bag 35, and a first clamping plate 8 is slidably arranged inside the relief grooves 32.

[0029] A third air-storing bladder 33 is provided between the end of the relief groove 32 away from the extrusion plate 31 and the corresponding first clamping plate 8. A third exhaust pipe 34 is provided between the third air-storing bladder 33 and the fourth air-storing bladder 35.

[0030] In the above technical solutions: When the automotive shock absorber bushing stamping part to be processed falls from the cylinder 6 into the groove above the conveyor plate 7, the bottom of the automotive shock absorber bushing stamping part is squeezed by the extrusion plate 31. The extrusion plate 31 compresses the fourth air storage bladder 35 downward. The gas inside the fourth air storage bladder 35 is discharged into the third air storage bladder 33 in the two side relief grooves 32 through the third exhaust pipe 34. After the third air storage bladder 33 is inflated, it pushes the first clamping plate 8 to slide along the relief groove 32 towards the center of the groove, automatically clamping and positioning the bushing blank that falls into the groove, avoiding the problem of insufficient stamping accuracy caused by blank displacement during the stamping process.

[0031] After the stamping is completed, the conveyor plate 7 exits the stamping station, the bushing is removed and no longer squeezes the extrusion plate 31, the fourth air storage bag 35 resets, the gas inside the third air storage bag 33 flows back, and the third reset spring drives the first clamping plate 8 to reset and release, so that the next round of feeding and clamping operation can be carried out.

[0032] Simultaneously, when the conveyor plate 7 moves below the material cylinder 6, the third air storage bladder 33 on the conveyor plate 7 squeezes the top holding rod 38, and the top holding rod 38 slides into the third receiving groove 37, compressing the fifth air storage bladder 39. The gas inside the fifth air storage bladder 39 is discharged into the sixth air storage bladder 45 in the fourth receiving groove 41 through the fourth exhaust pipe 40. The sixth air storage bladder 45 inflates and pushes the second clamping plate 36. At this time, the second clamping plate 36 no longer clamps the bottom automotive shock absorber bushing stamping inside the material cylinder 6, and the bottom automotive shock absorber bushing stamping falls onto the conveyor plate 7. When the third air storage bladder 33 and the top holding rod 38 are misaligned, the second clamping plate 36 clamps the bottom automotive shock absorber bushing stamping inside the material cylinder 6, preventing the blank from falling with the previous bushing, ensuring that only one bushing blank is fed each time, realizing automatic intermittent feeding, without the need for an additional power mechanism to stop the material, making the structure simpler and more reliable.

[0033] This invention is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the scope of protection of this invention.
