Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] The following is combined with Figures 1-3 This invention describes the specific implementation of the automatic keel riveting system.

[0025] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides an automatic keel riveting system, including: a stamping riveting device 10, including a bracket 11, a riveting die 12, and a driver 13, the riveting die 12 and the driver 13 being disposed on the bracket 11, the driver 13 being used to drive the riveting die 12 to perform riveting action; a conveying device 20, disposed on one side of the stamping riveting device 10, for conveying the keel to be riveted from the upstream of the production line to the stamping riveting device 10, for example, a belt conveyor; and a handling device 30, disposed on the bracket 11, the handling device 30 including a movable pallet 31 and a motion mechanism for driving the movable pallet 31 to move, under the drive of the motion mechanism, the movable pallet 31 can transport the keel on the conveying device 20 to the riveting position corresponding to the riveting die 12.

[0026] Specifically, the automatic keel riveting system achieves continuous operation of the keel end riveting process through an integrated automated structural design. The conveying device 20 can transport the upstream processed keel to the designated position in a rhythmic manner, the handling device 30 accurately grabs and positions the keel to the riveting station, and the stamping and riveting device 10 completes the efficient and stable riveting action under the command of the control system. The entire process requires no manual intervention, significantly improving production efficiency and product consistency.

[0027] In operation, the operator simply places the keel to be processed at the beginning of the production line, and the conveying device 20 automatically transports it to the riveting system inlet. Once the sensor detects the keel's arrival, the movable pallet 31 of the handling device 30 moves laterally under the drive of the motion mechanism, accurately clamping and transporting the keel to the riveting position of the riveting mold 12. Subsequently, the driver 13 starts, driving the mold to complete the riveting operation. After completion, the mold resets, and the movable pallet 31 moves the riveted keel away to continue the downstream process.

[0028] Preferably, the riveting mold 12 of the above-mentioned automatic riveting system for keels adopts a replaceable structure, which can quickly replace the appropriate mold core according to different specifications of keels, thereby improving the versatility of the equipment; the motion mechanism may include a servo motor and a synchronous belt drive assembly to achieve high-precision positioning control; the conveying device 20 may be equipped with an automatic centering mechanism to ensure that the keel maintains a centered posture during the conveying process, thereby improving the stability of subsequent handling and riveting.

[0029] Furthermore, according to the automatic riveting system for keels of this utility model, a fixed support plate 32 is also provided on the bracket 11, and the fixed support plate 32 is parallel to the movable support plate 31. The fixed support plate 32 is adjacent to the riveting mold 12, and the keel is supported on the fixed support plate 32 at the riveting position. Specifically, the fixed support plate 32 is used to provide stable support for the keel during the riveting process, avoiding displacement or deformation of the keel due to the impact force, thereby improving the riveting accuracy and the quality of the finished product. The fixed support plate 32 and the movable support plate 31 work together to ensure that the keel can be smoothly transitioned and positioned after being transported to the riveting position, ensuring the continuity and reliability of the riveting process.

[0030] Furthermore, according to the automatic riveting system for keels of this utility model, the fixed support plate 32 and the movable support plate 31 are respectively provided with multiple positioning teeth 33; the tooth shape of the positioning teeth 33 is adapted to the cross-sectional shape of the keel; the position of the positioning tooth 33 on one of the fixed support plates 32 corresponds to the riveting position. Specifically, the design of the positioning teeth 33 can effectively realize the automatic centering and clamping function of keels with different cross-sectional shapes (such as U-shaped, C-shaped, etc.), preventing the keel from sliding or shifting during the conveying and riveting process. When the movable support plate 31 transports the keel to the riveting position, the positioning teeth 33 on it are precisely aligned with the positioning teeth 33 on the fixed support plate 32.

[0031] Furthermore, according to the automatic riveting system for keel according to this utility model, the motion mechanism includes: a first slide 34, disposed on the bracket 11; a second slide 35, disposed on the first slide 34, and the moving direction of the second slide 35 is perpendicular to that of the first slide 34; and a movable support plate 31 disposed on the second slide 35. Specifically, this dual-axis linkage slide structure realizes precise displacement control of the movable support plate 31 in both horizontal and vertical directions. For example, the first slide 34 is responsible for driving the second slide 35 to move laterally to realize the transfer of the keel from the conveying device 20 to the riveting position; the second slide 35 drives the movable support plate 31 to move up and down to complete the loading and releasing action of the keel.

[0032] Furthermore, according to the automatic keel riveting system of this utility model, the first slide 34 drives the second slide 35 to move horizontally, and the second slide 35 drives the movable pallet 31 to move vertically; wherein, at the lowest stroke position of the second slide 35, the height of the movable pallet 31 is lower than that of the fixed pallet 32. Specifically, this structural design allows the movable pallet 31 to enter the area of ​​the conveying device 20 to grab the keel in a low position, and to raise the keel to a height above the fixed pallet 32 ​​during the upward movement, thereby achieving a smooth transition and accurate positioning of the keel. By setting the movable pallet 31 to be lower than the fixed pallet 32 ​​at its lowest point, interference between the keel and the fixed pallet 32 ​​during transportation can be effectively avoided, while facilitating the smooth landing of the keel end onto the positioning teeth 33 corresponding to the riveting position of the fixed pallet 32, thus improving the system's operational stability and efficiency.

[0033] Furthermore, according to the automatic riveting system for keel according to this utility model, the stamping and riveting device 10 includes a mold frame 14 disposed on a bracket 11; the driver 13 includes a pneumatic-hydraulic booster cylinder disposed on the mold frame 14; the riveting mold 12 includes a mold base and a mold upper seat disposed within the mold frame 14, the mold upper seat being installed at the output end of the pneumatic-hydraulic booster cylinder, and moving closer to or further away from the mold base under the drive of the pneumatic-hydraulic booster cylinder. Specifically, the pneumatic-hydraulic booster cylinder combines the advantages of high thrust of hydraulics and fast pneumatic response, and can provide stable and strong stamping force in a short time to meet the requirements of high-strength riveting. Preferably, a guide structure is provided between the mold base and the mold upper seat to ensure that the upper and lower molds remain aligned during the closing process, avoiding riveting defects caused by misalignment.

[0034] Furthermore, according to the automatic riveting system for keels of this utility model, the mold frame 14 includes a top plate and two side plates supported between the top plate and the bracket 11; each of the two side plates is provided with a C-shaped slot 15. During the handling of the keel, the end of the keel can move into or out of the riveting position between the two side plates through the C-shaped slot 15 of the side plate. Specifically, the design of the C-shaped slot 15 provides an entry and exit channel for the end of the keel, allowing the handling device 30 to send the keel into or out of the riveting area without obstruction, avoiding the space restriction problem caused by the traditional closed mold structure. At the same time, the side plates, as the main load-bearing structure, enhance the overall rigidity of the mold frame 14, which helps to maintain structural stability during high-pressure riveting.

[0035] Furthermore, according to the present invention, an automatic keel riveting system includes two opposing stamping and riveting devices 10; the conveying devices 30 on the two stamping and riveting devices 10 operate synchronously to respectively convey the two ends of the keel; a horizontal moving track 16 is provided at the bottom of the support 11 of one of the stamping and riveting devices 10, allowing the stamping and riveting device 10 to move closer to or away from the other stamping and riveting device 10 via the horizontal moving track 16. Specifically, this dual-station symmetrical arrangement is suitable for simultaneous riveting operations at both ends of a long keel, ensuring consistency of riveting actions at both ends through a synchronous control system, thereby improving overall processing efficiency. The movable support 11, in conjunction with the horizontal track, allows for flexible adjustment of the distance between the two stamping devices according to the keel length, thus achieving compatible production of various specifications of products and enhancing the versatility and adaptability of the equipment.

[0036] Furthermore, according to the automatic keel riveting system of this utility model, the stamping riveting device 10, the conveying device 20, and the handling device 30 are each equipped with position sensors for detecting the position of the keel. Specifically, the position sensors monitor the position status of the keel in each stage in real time, ensuring coordinated and orderly operation between components and preventing malfunctions or collisions. For example, when the sensor detects that the keel is not in position, the system will pause subsequent actions and issue an alarm until the position is confirmed to be normal before continuing the riveting process. This intelligent feedback mechanism significantly improves the automation level and operational safety of the system, contributing to the realization of unmanned continuous production.

[0037] The keel automatic riveting system according to a preferred embodiment of this utility model adopts an integrated and programmed control structure. It achieves automated riveting operations by setting two sets of sliding cylinders and two sets of pneumatic-hydraulic booster cylinders. Specifically, the first sliding table 34 drives the second sliding table 35 to move horizontally, while the second sliding table 35 drives the movable pallet 31 to move vertically. The movable pallet 31 lifts the keel upwards from below the conveying device 20, transports it above the fixed pallet 32, and then lowers it, allowing the keel to land smoothly on the fixed pallet 32, thus achieving precise positioning and handover.

[0038] The system is equipped with multiple position sensors to detect the position of the keel in real time during conveying, handling, and riveting processes, ensuring coordinated action between components and preventing equipment damage or processing failures due to misalignment or incomplete positioning. The stamping and riveting device 10 consists of a mold frame 14, a pneumatic-hydraulic booster cylinder, a mold base, and a mold upper seat. The mold frame 14 is composed of a top plate and two side plates, with C-shaped slots 15 on the side plates to facilitate the entry and exit of the keel end into the riveting area. The pneumatic-hydraulic booster cylinder provides a stable 5-ton stamping pressure, replacing the traditional 16-ton vertical punch press, significantly reducing equipment operating noise, improving operational safety, and ensuring the consistency and reliability of riveting quality.

[0039] Furthermore, the system can be configured with a dual-station symmetrical structure, including left and right stamping and riveting devices 10, which respectively handle the riveting tasks at both ends of the keel. One of the stamping and riveting devices 10 has a horizontal moving track 16 at its bottom, which can flexibly adjust the spacing according to the keel length to adapt to the production needs of different specifications of products. The entire system achieves fully automated operation from keel conveying, positioning, riveting to unloading, effectively reducing manual intervention, improving production efficiency, and shortening the delivery cycle, making it suitable for the actual needs of modern industrialized and large-scale production.

[0040] This utility model also provides a production line for ceiling keel products, which includes the automatic keel riveting system described in the above embodiments. The production line for ceiling keel products provided by this utility model is described below, and the description of the production line for ceiling keel products below corresponds to the description of the automatic keel riveting system above.

[0041] Specifically, the ceiling keel production line provided by this utility model integrates the aforementioned automatic keel riveting system. Preferably, it also includes multiple functional modules arranged sequentially, such as a feeding device, a punching device, a fixed-length cutting device, and a finished product collection device. These modules are interconnected via an automated conveyor line. During production, the profiles are first straightened and cut to a specified length to form keel blanks. These blanks are then conveyed by the conveyor 20 to the automatic riveting station, where the automatic keel riveting system precisely positions and efficiently rivets the ends. The entire production line uses a PLC centralized control system to achieve coordinated operation between processes, ensuring consistent processing rhythm and stable, reliable operation.

[0042] Furthermore, the production line can be equipped with multiple sensors and a vision positioning system to monitor the position and posture of the keel at each workstation in real time, ensuring that the keel is in the correct state before riveting and avoiding process defects caused by misalignment or displacement. Meanwhile, the pneumatic-hydraulic booster cylinder in the riveting system can adjust pressure parameters according to the riveting requirements of different keel models, improving the adaptability and flexibility of the equipment.

[0043] In summary, the ceiling keel production line provided by this utility model not only improves the automation level and processing accuracy of keel end riveting, but also significantly reduces manual intervention and labor intensity, thereby improving overall production efficiency and product quality stability.
