Description

Technical Field

[0001] This invention belongs to the technical field of automated punching equipment, and specifically relates to a punching device for sealing components. Background Technology

[0002] Automotive seals mainly consist of a lower gasket, an intermediate gasket, and an upper gasket. The upper gasket is installed inside the upper part of the lower gasket, and the intermediate gasket is placed between the lower and upper gaskets. In production, multiple gaskets need to be assembled in sequence and then punched to form a complete product. Most existing punching production lines rely on manual or semi-automatic methods to place the steel ring seals on a mold or positioning table, and then punch them using a stamping mechanism. After punching, the seals are removed, and then a new seal is placed in, and the stamping mechanism is used again for punching. This method requires manual handling of the seals, resulting in low punching efficiency. In addition, in conventional punching methods, the seals are placed directly in the mounting holes on the mold, relying solely on a single mounting hole for positioning. During long-term punching, vibration can cause slight displacement of the seals, leading to deviations in the punched position and affecting the subsequent assembly quality. Summary of the Invention

[0031] The assembled sealing ring 40 is placed onto the clamping assembly 30 by automated equipment, and then punched using this device. The automated equipment for placing the sealing ring 40 onto the clamping assembly 30 is not the technical solution to be protected in this application, but is implemented using existing conventional technology, and will not be described in detail here.

[0032] like Figures 1 to 8As shown: This application discloses a sealing punching device, including a support frame 10 for providing support force; a rotating assembly 20 disposed on the upper end of the support frame 10; a clamping assembly 30 disposed on the rotating assembly 20 for clamping a sealing ring 40; and a punching assembly 50 disposed above the rotating assembly 20 for punching the sealing ring 40, the punching assembly 50 being disposed on a bracket 54.

[0037] The positioning component 31 includes a positioning seat 311, two positioning heads 312, and two guide rods 313. The positioning seat 311 is circumferentially arranged on the upper surface of the rotating disk 22. A positioning hole 3111 is provided in the center of the upper end of the positioning seat 311. The sealing ring 40 is disposed in the positioning hole 3111. One end of each of the two positioning heads 312 abuts against the sealing ring 40. The ends of the two positioning heads 312 near the sealing ring 40 have a curved surface structure, and the curvature of the curved surface structure is consistent with the curvature of the outer ring of the sealing ring 40. Sliding grooves 3112 are provided on both sides of the positioning hole 3111 on the upper surface of the positioning seat 311. The two positioning heads 312 are respectively slidably positioned... The positioning head 312 is placed in the corresponding slide groove 3112. Two guide rods 313 are respectively set in the corresponding slide groove 3112. One end of the guide rod 313 slides through the side of the positioning head 312 away from the positioning hole 3111, and the other end of the guide rod 313 extends out of the positioning seat 311. A first spring 314 is provided between the positioning head 312 and the positioning seat 311. The positioning head 312 can slide along the slide groove 3112 to clamp or release the sealing ring 40. Each positioning head 312 has a fixed shaft 315 vertically arranged on its upper surface. The clamping member 32 can clamp the two fixed shafts 315 and move them toward the sealing ring 40.

[0038] The positioning component 31 also includes a positioning head adjusting component 33, which includes two adjusting rods 331 and two adjusting plates 332. The two adjusting plates 332 are respectively vertically arranged on both sides of the positioning seat 311. The end of the guide rod 313 away from the positioning head 312 is inserted into the adjusting plate 332. The adjusting rod 331 is rotatably arranged inside the positioning seat 311. The adjusting rod 331 is located at the lower end of the guide rod 313. The adjusting rod 331 and the guide rod 313 are parallel to each other. The end of the adjusting rod 331 that extends out of the positioning seat 311 is inserted into the adjusting plate 332. The adjusting rod 331 can drive the adjusting plate 332 to move closer to or away from the positioning seat 311.

[0039] The clamping member 32 includes a first cylinder 321 and a clamping head 322. The first cylinder 321 is mounted on the fixed plate 21. The output end of the first cylinder 321 is provided with a first locking block 323. The fixed end of the clamping head 322 is located inside the first locking block 323. The clamping end of the clamping head 322 has an arc-shaped structure. Both sides of the clamping end of the clamping head 322 can abut against the outer side wall of the fixed shaft 315 and move the two fixed shafts 315 toward the side closer to the sealing ring 40.

[0040] The clamping working principle of the sealing ring 40 is as follows:

[0041] The sealing ring 40 is placed inside the positioning hole 3111. At this time, the positioning heads 312 on both sides of the positioning hole 3111 abut against the side wall of the sealing ring 40. The first spring 314 applies a preload force to the positioning heads 312, which initially fixes the sealing ring 40. Simultaneously, the depth to which the adjusting rod 331 is inserted into the positioning seat 311 can be adjusted, thereby adjusting the distance between the adjusting plate 332 and the positioning seat 311. When the adjusting plate 332 moves away from the positioning seat 311, the guide rod 313 also moves away from the positioning seat 311 along with the adjusting rod 331. Therefore, the guide rod 313 drives the positioning head 312 to move away from the positioning seat 311. This adjustment method allows for the adjustment of the preload force applied by the positioning head 312 to the sealing ring 40.

[0042] When the positioning seat 311 with the sealing ring 40 rotates to the bottom of the stamping assembly 50, the corresponding clamping member 32 will strengthen the pre-tightening force on the sealing ring 40. Under the push of the first cylinder 321, the clamping head 322 will clamp onto the two fixed shafts 315 and clamp the two fixed shafts 315 towards the sealing ring 40.

[0043] The stamping assembly 50 includes a second cylinder 51 and a stamping rod 52. The second cylinder 51 is vertically arranged at the upper end of the bracket 54.

At the same time, the second push rod 721 and the second telescopic rods 722 are both inserted into the unloading frame 71.

[0048] The punching process includes the following steps:

[0049] Positioning of the fixing rod 63: First, the sealing ring 40 is positioned by the fixing component 60. When the positioning seat 311 with the sealing ring 40 rotates to below the stamping rod 52, the electric push rod 80 is driven to move upward. At this time, the base plate 81 will rise, and then the first telescopic member 62 will be driven to move upward through the connecting rod 82. The first telescopic member 62 will drive the fixing rod 63 to move upward. Finally, the fixing rod 63 passes through the rotating disk 22, inserts into the positioning seat 311, and abuts against the lower surface of the sealing ring 40, thus achieving vertical positioning.

[0050] Punching: The second cylinder 51 drives the punching rod 52 to move downward, and the reaming punch 53 is used to punch holes. After punching is completed, the drive motor 24 drives the rotating shaft 25 to rotate the rotating disk 22 to move the positioning seat 311 to be punched to the bottom of the punching rod 52 for punching.

[0051] When the positioning seat 311 corresponding to the punched sealing ring 40 rotates above the stripping assembly 70, stripping is performed, specifically as follows:

[0052] The electric push rod 80 is driven to move upward, at which time the base plate 81 will rise. Then, the connecting rod 82 drives the second telescopic member 72 to move upward. The second telescopic member 72 will drive the unloading member 73 to move upward as a whole. During the upward movement, since the position of the baffle 76 remains unchanged, the annular protrusion 7321 at the bottom of the outer cylinder 732 will move closer to the baffle 76. When the annular protrusion 7321 and the baffle 76 come into contact with each other, the outer cylinder 732 has pushed the sealing ring 40 upward out of the positioning hole 3111. Then, the second telescopic member 72 continues to drive the inner rod 731 to move upward. The outer cylinder 732 is held still by the baffle 76. At this time, the second spring 733 will be compressed, causing the inner rod 731 to move upward. The positioning protrusion 7311 on the inner rod 731 slides in the positioning groove 7322. Finally, the inner rod 731 pushes the sealing ring 40 upward from the rotating disk 22, forming a parabola, so that the sealing ring 40 falls to the outside of the rotating disk 22.

[0053] Since the positioning head 312 is provided on the positioning seat 311, and the positioning head 312 applies a pre-tightening force to the sealing ring 40, in order to ensure the smoothness of the unloading process, this device also includes an auxiliary component 90. The auxiliary component 90 includes a third cylinder 91 and a separating clamp 92. The third cylinder 91 is mounted on the fixed plate 21, and a second locking block 93 is provided at the output end of the third cylinder 91. The fixed end of the separating clamp 92 is located inside the second locking block 93. The clamping end of the separating clamp 92 is triangular, and the two sides of the clamping end of the separating clamp 92 can abut against the inner sidewalls of the fixed shafts 315 that are close to each other, and move the two fixed shafts 315 away from the sealing ring 40. At the same time, the first spring 314 can be used to automatically return to the initial position after the positioning head 312 is separated by force.

[0054] The operating principle of this device is as follows:

[0055] The seal is placed in the positioning position of the positioning seat 311 by manual operation or external equipment. The drive motor 24 drives the rotating disk 22 to rotate, causing one of the clamping components 30 to rotate below the stamping component 50. The first cylinder 321 drives the clamping head 322 to move towards the fixed shaft 315 and pushes the two fixed shafts 315 closer to each other, causing the positioning head 312 to move in the direction of mutual approach, thereby reliably clamping the sealing ring 40.

[0056] The electric push rod 80 extends and retracts, causing the base plate 81 to move upward. The base plate 81, through the connecting rod 82, causes the first telescopic component 62 to move upward. Finally, the fixing rod 63 abuts against the lower surface of the sealing ring 40, providing accurate support and positioning.

[0057] Subsequently, the second cylinder 51 drives the stamping rod 52 to move downwards, and the expanding punch 53 of the stamping rod 52 aligns with the sealing ring 40 to perform a stamping and expanding operation. After the punching is completed, the second cylinder 51 retracts, the stamping rod 52 resets, and the electric push rod 80 drives the fixing rod 63 to exit the sealing ring 40. The first cylinder 321 resets, the fixing shaft 315 is released, and the positioning head 312 returns to its initial state under the action of the first spring 314.

[0058] During the stamping process of the fixed rod 63 positioning the sealing ring 40, the upward movement of the base plate 81 will simultaneously drive the second telescopic member 72 to move upward. The second telescopic member 72 will drive the second contact plate 74 to move upward. The second contact plate 74 will drive the inner rod 731 and the outer cylinder 732 to move upward synchronously. At this time, the outer cylinder 732 has pushed the sealing ring 40 upward out of the positioning hole 3111. Then, the second telescopic member 72 continues to drive the inner rod 731 to move upward. The outer cylinder 732 is held still by the baffle 76. At this time, the second spring 733 will be compressed, causing the inner rod 731 to move upward. The positioning protrusion 7311 on the inner rod 731 slides in the positioning groove 7322. Finally, the inner rod 731 pushes the sealing ring 40 upward from the rotating disk 22, forming a parabola, so that the sealing ring 40 falls to the outside of the rotating disk 22, completing the unloading action. When the electric push rod 80 returns to its original position, the second spring 733 releases its elastic force, pushing the inner rod 731 back into the outer cylinder 732, and the unloading assembly 70 returns to its initial state, ready for the next cycle.

[0059] Therefore, the punching stage of the stamping component 50 and the stripping stage of the stripping component 70 are carried out simultaneously.

[0060] Through the above design, the stripping component 70 of this embodiment can realize the automatic separation of stamped workpieces, avoiding manual intervention and jamming, and improving the automation level and work efficiency of the production line.
