The device can greatly improve the punching efficiency of the sealing strip, reduce the labor intensity of workers, save labor costs, and reduce safety hazards.

[0004] However, this separate production method of punching and blanking not only increases the complexity of the production line, but also leads to low production efficiency and rising costs. In addition, due to the conversion and handling between procedures, errors are easily generated, affecting the precision and consistency of the product.

Therefore, it is an urgent need in the industry to develop a new type of tool that can integrate the punching and cutting procedures. Such an integrated tool not only simplifies the production process and reduces the equipment footprint, but also improves production efficiency and product precision, and reduces production costs.

[0016] In some embodiments of the present application, the base is provided with a cutting station and two punching stations, and the end of the sealing strip to be processed passes through the cutting station, the substrate, the punching station, the substrate, and the punching station in sequence.

[0017] Integrating the cutting and punching processes in one tool reduces the conversion and handling between processes, improving production efficiency.

[0018] In some embodiments of the present application, the cutting station includes an upper pressing seat and a cutting base, and a groove is formed between the bottom surface of the upper pressing seat and the top surface of the cutting base, which is adapted to the cross section of the sealing strip. The upper pressing seat is connected to a cutting power cylinder.

[0019] In the present application, the limit rod assembly effectively limits the movement trajectory of the upper pressing seat, and the elastic buffer assembly makes the upper pressing seat flexible when it is pressed down, avoiding damage to the sealing strip.

[0036] The present application will now be described in detail with reference to the accompanying drawings.

[0037] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0038] A new type of tooling for punching and cutting headlight sealing strips in one step, as shown in Example 1. Figure 1 As shown, the device includes a base 1, on which a cutting station 2, several punching stations 3, and a length-fixed detection component 4 for detecting the position of the sealing strip are provided. This integrated design effectively reduces potential errors when transferring the sealing strip between different toolings. This improves the accuracy of the sealing strip's dimensions and quality, ensuring it meets the required specifications.

[0039] One end of the sealing strip to be processed passes sequentially through cutting station 2 and several punching stations 3 until it contacts and connects with the fixed-length detection component 4. By integrating the punching and cutting operations into a single tooling, the production process is simplified. This reduces the number of individual tooling required and lowers the complexity of the production line. Furthermore, the combined operation allows for a more continuous workflow, which can increase production speed.

[0040] The fixed-length detection component 4 is movably mounted on the base 1. When the fixed-length detection component 4 moves to the forward direction of the sealing strip, it restricts the movement of the sealing strip. When the fixed-length detection component 4 moves away from the position of the sealing strip, the sealing strip can pass freely. The movable fixed-length detection component 4 further improves the processing accuracy of the sealing strip during cutting and punching, and does not affect the passage of the sealing strip after it is retracted, so that the formed long sealing strip can be continuously cut and punched.

[0041] This application achieves high-precision and high-efficiency sealing strip processing through an automated mechanical structure, reducing manual operation steps and simplifying the workflow.

[0042] Example 2, as Figures 1 to 4 As shown, multiple spaced-apart substrates 6 are mounted on the base 1. The substrates 6 are vertically arranged on the base 1, and a cutting station 2 or a punching station 3 is installed between two adjacent substrates 6. The design of the substrates 6 and the stations makes the tooling structure modular, which facilitates the adjustment of the number and position of the stations according to actual needs. The stations can be flexibly added, removed, or adjusted according to the processing requirements of different sealing strips to adapt to the production needs of multiple varieties and small batches.

[0043] Both the cutting station 2 and the punching station 3 include a top plate 7 and a base. The base is mounted on the base 1. The top of the base plate 6 has an embedding groove, into which the top plate 7 is inserted and locked to the base plate 6. A power cylinder is mounted on the top plate 7. The top plate 7 is locked to the base plate 6 via the embedding groove, simplifying the installation and disassembly of the station and facilitating maintenance and replacement. The locking design ensures the stability of the station, reduces vibration and offset during processing, and improves processing accuracy. The power cylinder is directly mounted on the top plate 7, making power transmission more direct and improving processing efficiency. The entire station is assembly and disassembly powered, further facilitating assembly and disassembly.

[0044] A channel 10 for a sealing strip to pass through is provided on the substrate 6 located between the punching station 3 and the cutting station 2 or the punching station 3. One end of the channel 10 is a flared structure with an end face diameter larger than the internal diameter, and the other end of the channel 10 is a straight structure adapted to the cross-section of the sealing strip. The flared structure facilitates the introduction of the sealing strip. The straight structure adapts to the cross-section of the sealing strip, ensuring the stability of the sealing strip during processing and improving processing accuracy.

[0045] The base 1 is provided with a cutting station 2 and two punching stations 3. One end of the sealing strip to be processed passes sequentially through the cutting station 2, the substrate 6, the punching station 3, the substrate 6, and the punching station 3. Integrating the cutting and punching processes into one fixture reduces the need for process changes and handling, thus improving production efficiency. In this application, the number and position of the punching stations 3 can be increased, decreased, or moved according to the processing requirements of the sealing strip to be processed.

[0046] The rest of the embodiment two is the same as embodiment one.

The limiting rod assembly 13 and the elastic buffer assembly 14 are arranged between the upper pressing seat 11 and the cutting base 12. The cutting power cylinder 8 drives the upper pressing seat 11 to move downward to press the solid sealing strip.

[0048] In the present application, the limiting rod assembly 13 effectively limits the movement track of the upper pressing seat 11, and the elastic buffer assembly 14 makes the upper pressing seat 11 have flexibility when it is pressed downward, so as to avoid damaging the sealing strip. The elastic buffer assembly 14 makes the upper pressing seat 11 have flexibility when it is pressed downward, so as to avoid damaging the sealing strip and improve the product quality.

[0049] The cutting tool 15 and the punching tool 16 are respectively arranged in the upper pressing seat 11. The cutting tool 15 and the punching tool 16 are respectively connected with the cutting power cylinder 8. The cutting power cylinder 8 drives the cutting tool 15 and the punching tool 16 to penetrate the upper pressing seat 11 and act on the sealing strip. In the present application, the cutting tool 15 and the punching tool 16 are integrated in the upper pressing seat 11, so as to realize synchronous processing and improve the production efficiency. The integrated design also reduces the error between processes and ensures the consistency of the cutting and punching precision.

[0050] The punching station 3 comprises a punching base 17. The punching base 17 is provided with a slot hole 18 through which the sealing strip passes.

The punching process in the present application is completely automated, which reduces manual operation and improves the production efficiency.

[0051] The punching base 17 is provided with a waste port 19 at the bottom. The waste port 19 is communicated with the slot hole 18. The waste generated by the punching of the sealing strip can directly fall out through the waste port 19. The waste is discharged in time, which avoids the influence of the accumulated waste on the machining precision and the operation of the equipment. At the same time, the frequency of manual cleaning is reduced, and the production efficiency is improved. Similarly, the waste port is also arranged at the corresponding position of the bottom of the cutting base 12 and the punching tool 16.

[0052] The base 1 is provided with a slide rail 20, a sliding block 22 connected with a straight cylinder 21 is installed on the slide rail 20, the fixed-length detection assembly 4 is installed on the sliding block 22, one of the base plates 6 is provided with an inductive device 23 for detecting whether the sealing strip is out, the inductive device 23, the straight cylinder 21 and the fixed-length detection assembly 4 are respectively connected with a control device 24; when the inductive device 23 detects that the sealing sleeve is out, the straight cylinder 21 is driven to work to drive the fixed-length detection assembly 4 to move to the advancing direction of the sealing strip; when the cutting station 2 and the punching station 3 complete the machining process, the straight cylinder 21 drives the fixed-length detection assembly 4 to move away from the position of the sealing strip. The fixed-length detection assembly 4 moves through the slide rail 20, ensuring that the machining length of the sealing strip is accurately controllable. The inductive device 23 is linked with the straight cylinder 21, the automatic movement of the fixed-length detection assembly 4 is realized, and manual intervention is reduced. Further, the fixed-length detection assembly 4 can be flexibly adjusted according to the length requirement of the sealing strip, and the machining requirement of different specifications is adapted.
