The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] The guardrail processing, cutting and forming apparatus of this application embodiment will now be described with reference to the accompanying drawings.

[0020] like Figures 1 to 6 As shown, the guardrail processing and cutting forming device of this application embodiment may include a support frame 1, a centering positioning component 2, multiple conveying components 3, multiple protective components 4, and a cutting mechanism 5 disposed on the support frame 1.

[0021] The support frame 1 has multiple support bars 9 evenly distributed inside, and there is a gap 10 between two adjacent support bars 9.

[0022] It should be noted that the top of the support bar 9 has a serrated structure, which can be welded and fixed inside the support frame 1 to support the guardrail blank. This serrated point contact greatly reduces the path and area of ​​heat conduction, so that the heat mainly accumulates near the cutting point and is blown away by the auxiliary gas, effectively avoiding heat damage and slag adhesion on the back side.

[0023] The inner walls of the support frame 1 are provided with multiple through slots 12, and multiple conveying components 3 are respectively arranged in the corresponding gaps 10 at intervals, with their two ends slidably connected to the corresponding through slots 12.

[0024] It should be noted that there is a gap 10 between two adjacent conveying components 3. The height of the conveying component 3 is adjustable, which facilitates the conveying of the cut guardrail panels without the need for mechanical adsorption equipment, thereby reducing the cost of the device and reducing the space occupied.

[0025] The two opposite sidewalls of the support frame 1 are respectively provided with adjustment components 6, and the two ends of the conveying component 3 are respectively connected to the corresponding adjustment components 6. The adjustment components 6 are used to adjust the height of the conveying component 3.

[0026] In the embodiments of this application, the height of the conveying component 3 can be adjusted by adjusting component 6. When the top of the conveying component 3 is higher than the support bar 9, the cut guardrail blank can be lifted and conveyed forward, which is convenient to operate and facilitates quick unloading.

[0027] Multiple protective components 4 are respectively disposed above the corresponding conveying components 3, and the protective components 4 are connected to the conveying components 3.

[0028] In the embodiments of this application, each conveying component 3 corresponds to a protective component 4. The protective component 4 is used to protect the conveying component 3, prevent molten slag from dripping onto the conveying component 3, ensure the cleanliness of the conveying component 3, and thus maintain stable conveying.

The first driving component 61 can lift the conveying component 3, so that the conveying component 3 is higher than the support bar 9, thereby realizing the support and conveying of the cut and shaped guardrail blank.

[0035] Furthermore, such as Figure 4 As shown, the conveying assembly 3 includes a conveying roller 31, a roller shaft 32 and two first sliders 33. The two first sliders 33 are slidably connected to the corresponding through grooves 12, and the first sliders 33 are connected to the lifting frame 62. The two ends of the roller shaft 32 are rotatably connected to the corresponding first sliders 33, and the conveying roller 31 is mounted on the roller shaft 32.

[0036] It should be noted that the roller 32 passes through the first slider 33, which slides up and down in the through groove 12. When the first drive unit 61 is started, it can drive multiple conveying components 3 to move up or down simultaneously.

[0037] Furthermore, one of the roller shafts 32 is connected to an external motor, which can drive the roller shaft 32 to rotate. Adjacent roller shafts 32 are connected by a belt. Specifically, a pulley is provided on the roller shaft 32, and adjacent pulleys are connected by a belt, thereby driving multiple roller shafts 32 to rotate synchronously.

[0038] In one embodiment of this application, such as Figures 2-4As shown, the protective assembly 4 includes two protective plates 41, a support shaft 42, two gears 43, and two toothed plates 44. The two support shafts 42 are symmetrically arranged below the gap 10, and one end of the support shaft 42 extends to the outside of the support frame 1. The two protective plates 41 are respectively arranged on the corresponding support shafts 42, and the two protective plates 41 form an inverted "V" shape after being closed. The two gears 43 are respectively arranged at both ends of the support shafts 42. The two toothed plates 44 are respectively arranged on the opposite sidewalls of the first slider 33 and have a meshing relationship with the corresponding gears 43.

[0039] In the embodiments of this application, the support shaft 42 is rotatably connected to the support frame 1, and the eaves structure formed by the two protective plates 41 can protect the conveying roller 31, thereby preventing the molten slag generated during cutting from dripping onto the conveying roller 31, and the inclined protective plates 41 will not affect the discharge of waste materials.

[0040] In one embodiment of this application, such as Figure 5 and Figure 6 As shown, the centering positioning component 2 includes a rotating plate 21, two push-pull plates 22, two connecting plates 23, multiple positioning rods 24, and multiple rotating rollers 25. The rotating plate 21 is rotatably disposed below the support plate 11. The two push-pull plates 22 are respectively disposed on both sides of the rotating plate 21, and their ends are respectively hinged to the rotating plate 21 and the connecting plate 23. The multiple positioning rods 24 are respectively disposed on the upper surface of the corresponding connecting plate 23, and the positioning rods 24 move within the gap 10. The multiple rotating rollers 25 are respectively disposed on the corresponding positioning rods 24.

[0041] It should be noted that a motor is installed on the lower surface of the support plate 11, and the rotating plate 21 is connected to the output end of the motor. The motor can drive the rotating plate 21 to rotate forward and backward. With the cooperation of the push-pull plate 22, the two connecting plates 23 are driven to move closer or further apart. When the connecting plates 23 move closer to each other, they drive the two sets of positioning rods 24 to move simultaneously toward the center of the guardrail blank, so that it is centered in the center of the support frame 1, ensuring the constant conveying position and ensuring the accuracy of subsequent extrusion molding.

[0042] Furthermore, both the positioning rod 24 and the conveying roller 31 are arranged in the gap 10, and the positioning rod 24 and the conveying roller 31 are arranged adjacent to each other. The top of the positioning rod 24 is higher than the guardrail blank, thereby ensuring that the guardrail can be pushed to the center position.

[0043] In one embodiment of this application, such as Figure 4 As shown, the two opposite inner walls of the support frame 1 are provided with receiving grooves 8. The receiving grooves 8 include a first groove 81 and a plurality of second grooves 82 communicating with the first groove 81. The first groove 81 is correspondingly provided with the connecting plate 23, and the second grooves 82 are correspondingly provided with the positioning rod 24.

[0044] It should be noted that when cutting and drilling holes in the guardrail panel, in order to prevent molten slag from dripping onto the connecting plate 23 and the positioning rod 24, the connecting plate 23 and the positioning rod 24 can be hidden in the receiving groove 8 to ensure that the positioning rod 24 is clean and tidy, thereby ensuring the positioning accuracy of the guardrail panel blank.

[0045] In one embodiment of this application, such as Figure 5 As shown, the guardrail processing and cutting forming device of this embodiment also includes two guide rails 7 parallel to the support bar 9. The two ends of the guide rails 7 are respectively embedded in the inner wall of the support frame 1. Two second sliders 14 are slidably connected on the guide rails 7. The two second sliders 14 are respectively connected to the corresponding connecting plates 23.

[0046] It should be noted that the two guide rails 7 are respectively set on both sides of the support plate 11, and the two ends of the guide rails 7 are inserted into the slots opened in the support frame 1, and the slots are connected to the receiving slots 8. The guide rails 7 and the second slider 14 can guide the two connecting plates 23 to ensure that the two connecting plates 23 can move in a straight line towards or away from each other.

[0047] In one embodiment of this application, such as Figure 1 As shown, the cutting mechanism 5 includes a second linear motion mechanism 51, a second drive member 52, and a laser cutter 53. The second linear motion mechanism 51 is mounted on the bracket 13, the second drive member 52 is connected to the slide of the second linear motion mechanism 51, and the laser cutter 53 is connected to the output end of the second drive member 52.

[0048] It should be noted that the second linear moving mechanism 51 is perpendicular to the first linear moving mechanism 15. The second linear moving mechanism 51 and the first linear moving mechanism 15 facilitate the movement of the laser cutting machine 53, and the second driving component 52 facilitates the adjustment of the height of the laser cutting machine 53, so that the height of the laser cutting machine 53 can be adjusted according to the thickness of the plate.

[0049] Furthermore, a guide roller 16 is rotatably connected to the support frame 1. The height of the guide roller 16 is higher than that of the support bar 9. The guide roller 16 facilitates the guidance of the cut guardrail blank to the extrusion equipment.

[0050] It is understandable that multiple straightening rollers are rotatably provided at the input end of the support frame 1. The multiple straightening rollers are arranged vertically, and the two straightening rollers arranged vertically rotate in opposite directions. While conveying the steel strip, they straighten the steel strip. The lower straightening roller is flush with the top of the support bar 9 so that the steel strip can be placed flat on the support bar 9.

[0051] Specifically, the front end of the strip steel plate is fed between two vertically arranged straightening rollers for straightening, and then flatly conveyed onto the support bar 9. The first linear movement mechanism 15 and the second linear movement mechanism 51 are started, driving the laser cutting machine 53 to move along a preset path, first cutting the steel strip into fixed-length blanks, and then cutting mounting holes on them to facilitate the installation of the support column.

[0052] Throughout the cutting process, the two protective plates 41 close to form an inverted "V" shape and remain above the conveyor roller 31, effectively preventing molten slag from dripping and keeping the roller surface clean.

[0053] After cutting, the relevant personnel activate the first drive components 61 on both sides of the support frame 1. The first drive components 61 drive the two lifting frames 62 upward, and the first slider 33 slides in the through groove 12, driving the conveyor roller 31 to rise until its top surface is higher than the support bar 9, thereby smoothly lifting the cut guardrail blank. At the same time, the upward movement of the first slider 33 drives the two toothed plates 44 to rise synchronously. Through the gear 43, the two support shafts 42 rotate in opposite directions, thereby opening the protective plate 41 and making way for the conveyor roller 31 to rise.

[0054] Then, the motor connected to the rotating plate 21 is started, and the rotating plate 21 rotates. Through the linkage of the push-pull plate 22, the two connecting plates 23 move towards each other until the rotating rollers 25 on them are tightly attached to both sides of the guardrail blank, completing the centering and lateral constraint of the blank.

[0055] Finally, start the conveyor roller 31 to rotate, driving the positioned blank to move smoothly towards the guide roller 16 until it is completely removed from the support frame 1, completing the unloading.

[0056] After the material is unloaded, the centering positioning component 2 resets first: the two connecting plates 23 move in opposite directions, causing the positioning rod 24 and connecting plates 23 to retract into the receiving groove 8. Subsequently, the conveying component 3 is lowered by the adjusting component 6, causing the conveying roller 31 to descend below the plane of the support bar 9. During this process, the first slider 33 moves down, driving the gear 43 to rotate in the opposite direction, causing the two protective plates 41 to close again, forming an inverted "V" shaped protective structure to continue protecting the conveying roller 31 below. This unloading method makes full use of the space between adjacent support bars 9 for lifting and conveying, is not limited by the length and width of the blank, eliminates the need for traditional large-scale adsorption equipment, saves installation and operating space, makes the production line layout more compact, and also achieves fast and automated unloading, thus improving overall efficiency.

[0057] In summary, the guardrail panel processing, cutting, and forming device of this application, by installing a liftable conveyor assembly between adjacent support bars, enables rapid unloading of guardrail panel blanks. This method is not limited by the length and width dimensions of the blanks and can significantly save equipment space, making the production line layout more compact.
