Description
Technical Field
[0001] This utility model relates to the field of automatic bending technology, and in particular to a fully automatic guardrail machine that automatically bends guardrails. Background Technology
[0002] In the field of guardrail manufacturing, bending and creasing are key processes to ensure the structural strength and installation adaptability of guardrails. Current technologies for guardrail processing often face the following technical bottlenecks: First, most guardrail processing equipment has a single function, only adapting to creasing of specific shapes or bending at fixed angles. When facing production needs of multiple specifications and shapes, it is necessary to disassemble and replace the entire set of processing components, making process switching cumbersome and time-consuming. Furthermore, the equipment lacks targeted auxiliary structural design, resulting in metal scraps scattering during processing, leading to a messy workshop environment and significant safety hazards. Spare processing parts lack an orderly storage solution. At the same time, the high degree of integration of the overall machine structure means that disassembly is required for fault repair, significantly reducing operational convenience and maintenance efficiency. Second, existing guardrail bending processing often adopts a discrete process mode, requiring manual intervention in key aspects such as raw material feeding, positioning calibration, and finished product transfer. This not only involves high labor intensity but also easily leads to processing deviations due to the uncertainty of manual operation, making it difficult to ensure product consistency. Simultaneously, traditional equipment drive and positioning systems lack a collaborative linkage mechanism, resulting in insufficient stability of processing parameters, further exacerbating the precision control problem and failing to meet the demands of large-scale production for efficient and precise processing.

[0016] Please see the appendix Figure 1 - Appendix Figure 5This utility model provides an embodiment of an automatic bending guardrail machine, comprising a front support 1, a front mounting cavity 3, and an infeed conveyor belt 4 within the front mounting cavity 3; a rear support 2, a rear mounting cavity 5, and an outfeed conveyor belt 6 within the rear mounting cavity 5; a drive motor 8 is mounted at one end of both the infeed conveyor belt 4 and the outfeed conveyor belt 6; through holes 7 are provided on one outer wall of the front support 1 and the rear support 2 at positions corresponding to the drive motor 8, and the output end of the drive motor 8 is fitted into the through holes 7; front and rear mounting seats 9 are fixedly connected on one outer wall of the front support 1 and the rear support 2 at positions corresponding to the drive motor 8; and front pressing bases are respectively provided on the inner walls of both sides of the front support 1 and the rear support 2. The front pressing groove 10 and the rear pressing groove 11 are respectively opened above the feeding conveyor belt 4 and the feeding conveyor belt 6. Their function is to laterally limit and guide the raw materials during the conveying process of the guardrail, to prevent the raw materials from deviating during feeding or feeding, and to ensure processing accuracy. A middle cavity 12 is opened between the front support 1 and the rear support 2. A mounting frame 13 is fixedly connected to the outer wall of the middle cavity 12. A hydraulic cylinder 14 is set on the upper surface of the mounting frame 13. A mounting rod 15 is fixedly connected to the output end of the hydraulic cylinder 14. A V-head pressure rod 16 is snapped on the bottom outer surface of the mounting rod 15. A mounting threaded hole 17 is opened on the V-head pressure rod 16. The mounting rod 15 is positioned corresponding to the mounting threaded hole 17. A fixing threaded hole 18 is provided at the mounting threaded hole 17. Fixing bolts 19 are threaded into both the mounting threaded hole 17 and the fixing threaded hole 18, thereby detachably fixing the V-head pressure rod 16 to the mounting rod 15. When it is necessary to replace the pressure rod with a different shape, it can be quickly replaced by removing the fixing bolts 19. A waste collection trough 30 is provided between the front bracket 1 and the rear bracket 2, corresponding to the position of the V-head pressure rod 16. A storage trough 31 is provided below the waste collection trough 30. The waste collection trough 30 and the storage trough 31 are located below the front bracket 1 and the rear bracket 2. An arc-shaped head pressure rod 32 and a rectangular head pressure rod 33 are provided in the storage trough 31. The arc-shaped head pressure rod 32 and the rectangular head pressure rod 33 are respectively positioned at the positions corresponding to the fixing threaded hole 18. The device has a threaded mounting hole 17 and a waste collection trough 30 for collecting metal shavings and other waste generated during the bending process. The storage trough 31 is used to store spare arc-shaped head pressure rods 32 and rectangular head pressure rods 33 for easy replacement. The design of the threaded mounting hole 17 is the same as that of the V-head pressure rod 16, ensuring interchangeability. An indentation cavity 20 is provided between the front bracket 1 and the rear bracket 2 at the position corresponding to the V-head pressure rod 16. A triangular indentation rod 21 is provided in the indentation cavity 20. V-shaped grooves 22, rectangular grooves 23 and arc-shaped grooves 24 are respectively provided on the three sides of the triangular indentation rod 21, so that the indentation rod can switch different groove shapes by rotating according to the processing requirements, thereby pressing V-shaped, rectangular or arc-shaped indentations on the guardrail.A central shaft 25 is provided at the center of the triangular indentation rod 21. A shaft hole 26 is provided on the indentation cavity 20 corresponding to the position of the central shaft 25, and the central shaft 25 is fitted into the shaft hole 26. This allows the central shaft 25 to drive the triangular indentation rod 21 to rotate stably within the indentation cavity 20, providing structural support for switching indentation groove types. A rotary motor 27 is provided at one end of the central shaft 25. A central mounting base 29 is fixedly connected to the outside of the indentation cavity 20 corresponding to the position of the rotary motor 27. An electromagnetic brake 28 is engaged with the rotary motor 27. The rotary motor 27 provides power for the rotation of the central shaft 25, the central mounting base 29 is used to fix the rotary motor 27, and the electromagnetic brake 28 is used to brake and lock the triangular indentation rod 21 after it has rotated to the desired position, ensuring positional accuracy during indentation.
[0017] Working principle: Using this utility model, firstly, a suitable V-head pressure rod 16, arc-shaped pressure rod 32, or rectangular pressure rod 33 is selected from the storage slot 31 located below the front bracket 1 and the rear bracket 2. The mounting threaded hole 17 on the pressure rod is aligned with the fixing threaded hole 18 on the mounting rod 15, and the fixing bolt 19 is screwed in to achieve a secure connection between the pressure rod and the mounting rod 15. The mounting rod 15 is then fixed to the output end of the hydraulic cylinder 14 on the upper surface of the mounting frame 13, which is fixedly connected to the outer wall of the central cavity 12. At that time, according to the indentation requirements, the rotary motor 27 installed on the central mounting base 29 is started, which drives the central shaft 25 of the triangular indentation rod 21 to rotate in the shaft hole 26 of the indentation cavity 20. After switching the V-shaped groove 22, rectangular groove 23 or arc groove 24 on the triangular indentation rod 21 to the processing position, the central shaft 25 is locked by the electromagnetic brake 28 engaged on the rotary motor 27 to ensure accurate positioning of the indentation groove. After the equipment is started, the drive motor 8 passes through the outer wall of one side of the front support 1 and the rear support 2. The output power of hole 7 drives the feed conveyor belt 4 in the front mounting cavity 3 and the output conveyor belt 6 in the rear mounting cavity 5 to operate synchronously. The drive motor 8 is firmly installed on the outer wall of the bracket through the front and rear mounting seats 9. The guardrail material is placed on the feed conveyor belt 4. Under the guidance and limiting action of the front pressing groove 10, the material is smoothly transported to the processing area between the front bracket 1 and the rear bracket 2. First, it passes through the indentation cavity 20. The preset groove of the triangular indentation rod 21 contacts the surface of the material to complete the indentation process. Then, the material continues to be transported to the V-head pressing rod 16 or the arc-shaped pressing rod 32 or the rectangular pressing rod 33. The hydraulic cylinder 14 starts to output pressure, driving the mounting rod 15 to move the pressing rod downward. With the help of the supporting structure below, the guardrail is bent and formed. The metal scraps generated during the processing fall into the waste collection groove 30 below the V-head pressing rod 16 and are collected. The finished guardrail after bending is transported to the outside of the equipment by the output conveyor belt 6 under the guidance of the rear pressing groove 11, completing the fully automatic processing.
