Description

Technical Field

[0001] This utility model relates to the field of sealing strip processing technology, and in particular to an electric fixed-distance punching device for sealing strips. Background Technology

[0002] Sealing strips are products used to fill gaps, prevent leaks, and provide functions such as shock absorption, waterproofing, and sound insulation. They are typically made of rubber, plastic, metal, or other materials and possess a certain degree of elasticity and compressibility. Sealing strips are widely used in various industrial and construction applications, such as doors and windows, automobiles, and machinery.

[0003] To ensure a secure installation and improved sealing effect, automotive sealing strips are typically perforated. These holes are primarily for mounting clips, facilitating the assembly of the sealing strip with the vehicle body. Additionally, the breather holes on the sealing strip, as a special design feature, mainly function to balance internal and external pressure differences, ensuring stable product performance under various conditions.

[0004] Existing punching equipment, due to limitations in the punching dies, cannot punch multiple holes in sealing strips. Furthermore, since the punching process is mostly manual, it's difficult to ensure consistent spacing between holes. Additionally, the lack of securing measures when placing the sealing strip on the punching table easily leads to deviations in the punching position, further affecting the sealing effect and installation quality. Therefore, to address these issues, an electric fixed-distance punching device for sealing strips is proposed. Utility Model Content

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of an electric fixed-distance punching device for sealing strips, including an operating platform 1. The bottom of the operating platform 1 has a square frame structure to effectively support the stability of the operating platform 1. A support frame 2 is fixedly connected to the top of the operating platform 1. The support frame 2 is located at the rear of the top of the operating platform 1, providing an installation position for components such as a hydraulic cylinder 3 and an infrared positioner 14. A hydraulic cylinder 3 is fixedly connected to the middle of the top of the support frame 2. The hydraulic cylinder 3 drives the punching structure to press down and punch the sealing strip. A support plate 4 is fixedly connected to the drive end of the hydraulic cylinder 3, and the support plate 4 provides support and an installation position for the punching head 11.

[0034] A connecting plate 5 is fixedly connected to the bottom end of the support plate 4, providing a sliding track for the limiting sleeve 12. Two slide bars 6 are fixedly connected to the front side of the support plate 4, located on the left and right sides of the support plate 4, providing guidance for the movement of the slide plate 8. Two hydraulic cylinders 7 are fixedly connected to the top end of the support plate 4, and the slide plate 8 is fixedly connected to the drive end of the two hydraulic cylinders 7. The left and right ends of the rear side of the slide plate 8 are slidably connected to the outside of the slide bars 6. Activating the extension and retraction of the hydraulic cylinders 7 can push the slide plate 8 to slide on the slide bars 6. An infrared positioner 14 is provided on the front side of the top of the support frame 2. The infrared positioner 14 irradiates infrared rays onto the punching table 15 to help the operator place the adhesive strip and ensure the accurate positioning of the adhesive strip.

[0035] refer to Figure 3 The slide plate 8 has multiple inclined grooves 9 in its middle section. Each inclined groove 9 is a long, sloping through-hole groove, centered on the middle of the slide plate 8. A sliding roller 10 is slidably connected inside the inclined groove 9. Fixed heads are located at both ends of the sliding roller 10. By sliding within the inclined groove 9, the roller drives the punching head 11 to move. The punching head 11 is fixedly connected to the middle of the sliding roller 10. The punching head 11 is used to punch the sealing strip. A limiting sleeve 12 is slidably connected to the outside of the punching head 11. A second sliding strip 13 is fixedly connected to the front side of the connecting plate 5. The rear sides of the multiple limiting sleeves 12 are slidably connected to the outside of the second sliding strip 13. The limiting sleeves 12 are slidably connected to the second sliding strip 13 of the connecting plate 5, assisting the punching head 11 in its movement, limiting the direction of movement of the punching head 11, and ensuring the accuracy of the punching. A punching platform 15 is fixedly connected to the top of the operating table 1, providing a working platform for punching the sealing strip.

[0036] refer to Figure 4 , Figure 5 Two fixing components are fixedly connected to the rear side of the punching table 15. Each fixing component includes two support members 16. The bottom ends of the two support members 16 are fixedly connected to the left and right ends of the rear side of the punching table 15, and the top ends of the support members 16 are fixedly connected to a hydraulic cylinder 17. The support members 16 provide an installation position for the hydraulic cylinder 17. A transmission rod 18 is fixedly connected to the drive end of the hydraulic cylinder 17, and a groove is provided at the top end of the transmission rod 18. Under the action of the hydraulic cylinder 17, the transmission rod 18 moves up and down, pushing the connecting plate 21 and the push rod 22, thereby driving the spine 25 and the pressure plate 26 to fix and level the rubber strip.

[0037] A guide rod 19 is slidably connected to the middle of the bottom end of the transmission rod 18, and the guide rod 19 provides guidance for the movement of the transmission rod 18. A spring 20 is sleeved on the outside of the guide rod 19, and the top end of the spring 20 is fixedly connected to the bottom end of the transmission rod 18. The bottom end of the spring 20 is also fixedly connected to the top end of the support block 23. The spring 20 is compressed when the transmission rod 18 descends, providing an upward restoring force for the transmission rod 18.

[0038] A connecting plate 21 is fixedly connected to the outside of the transmission rod 18. A push rod 22 is rotatably connected to the bottom end of the connecting plate 21 on the side away from the transmission rod 18. The connecting plate 21 moves up and down with the transmission rod 18, pushing the push rod 22, thereby driving the spine rod 25 and the pressure plate 26 to move. A support block 23 is fixedly connected to the bottom end of the guide rod 19. The push rod 22 is slidably connected to the middle part of the support block 23 on the side away from the transmission rod 18. The support block 23 provides support for the guide rod 19, the rotating rod 24, and the push rod 22, and a through hole is opened on the side of the support block 23 away from the transmission rod 18. Two rotating rods 24 are rotatably connected to the top end of the support block 23 near the transmission rod 18. The rotating rods 24 provide support and guidance for the movement of the spine rod 25, ensuring the stable sliding of the pressure plate 26.

[0039] Two rotating rods 24 are rotatably connected to their bottom ends with a spine 25. The bottom end of a push rod 22 is rotatably connected to the side of the spine 25 away from the rotating rods 24. The spine 25, pushed by the push rod 22, drives the pressure plate 26 to move, fixing and leveling the sealing strip. The bottom end of the spine 25 is fixedly connected to the pressure plate 26, which is slidably connected to the top of the punching table 15. The pressure plate 26, driven by the spine 25, squeezes, fixes, and levels the sealing strip, ensuring that the sealing strip remains flat before punching. A conical cylinder 27 is fixedly connected to the middle of the punching table 15. The outer middle of the conical cylinder 27 is fixedly connected to the top middle of the operating table 1. The conical cylinder 27 is used to collect the waste material generated during the punching process.

[0040] Working Principle: In use, first place the adhesive strip on the punching table 15. Then, activate the infrared positioner 14, which irradiates the punching table 15 with infrared rays to help the operator accurately place the adhesive strip. After placing the adhesive strip, activate hydraulic cylinder 17, causing the pressure plate 26 to contact the adhesive strip and press it in place. Simultaneously, hydraulic cylinder 17 continues to operate, driving the transmission rod 18 downwards. As the transmission rod 18 extends and retracts downwards, it slides outside the guide rod 19 and compresses the spring 20. At the same time, as the transmission rod 18 descends, the connecting plate 21 fixed externally pushes the push rod 22 downwards along with the transmission rod 18. The connecting plate 21 passes through the push rod 22, pushing the spine 25 and the pressure plate 26 to slide on the surface of the adhesive strip towards hydraulic cylinder 17. This, combined with the rotating rod 24, supports the pressure plate 26, allowing it to slide stably and level the adhesive strip, ensuring the sealing strip remains flat before punching.

[0041] After the sealing strip is fixed, hydraulic cylinder 7 is activated first. Both hydraulic cylinders 7 extend and retract, pushing slide plate 8. Slide plate 8 slides outside slide bar 6, driving slide roller 10 to slide along the groove of inclined groove 9. Since punch head 11 is fixedly connected to slide roller 10, when slide roller 10 slides, punch head 11 will move centered with slide roller 10. The limiting sleeve 12, which slides externally at the bottom of punch head 11, assists in moving punch head 11 to adjust to a suitable punching spacing. After adjustment, hydraulic cylinder 3 is activated, which drives punch head 11 downwards through support plate 4 to punch the sealing strip fixed on punching table 15.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
