Detailed implementation manners

[0032] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear and understandable, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] Embodiment 1

[0034] Please refer to Figure 1-Figure 9 , the present invention provides a technical solution: a bending guiding mechanism for steel sheet pile production, and the bending guiding mechanism for steel sheet pile production includes: a conveying platform 1, a bending bracket 4, a pressure-bearing platform 5, and a sliding component 9.

[0035] Specifically, an arc-shaped convex platform 2 is fixedly arranged at the edge of the upper surface of the conveying platform 1, a workpiece 3 to be processed is attached to the upper surface of the conveying platform 1, and the arc-shaped convex platform 2 is used to protect the bending part of the workpiece 3 to be processed and ensure that a fillet can be formed when the edge of the workpiece 3 to be processed is bent, avoiding breakage;

[0036] Secondly, the bending bracket 4 is located just above the middle of the conveying platform 1, and the bending bracket 4 is pressed on the upper surface of the workpiece 3 to be processed, and the bending bracket 4 is used to bend the edge of the workpiece 3 to be processed;

[0037] Furthermore, the pressure platform 5 is fixedly arranged in the middle of the conveying platform 1 and is located directly below the bending bracket 4. The two sides of the pressure platform 5 are rotatably installed with limit baffles 6. The limit baffles 6 can be rotated and press the edge of the lower surface of the workpiece 3 to be processed from bottom to top, so as to guide and accurately control the bending angle of the workpiece 3 to be processed, avoid different bending angles at different places of the edge of the workpiece 3 to be processed, and ensure that the surface of the workpiece 3 to be processed remains flat after bending. The inner side of the limit baffle 6 is fixedly connected to the connecting plate 7, and the lower edge of the connecting plate 7 is fixedly connected to the connecting column 8;

[0038] In addition, the sliding component 9 is slidably installed on the side of the pressure platform 5 and is driven to move by the driving stud 15. The sliding component 9 includes a connecting block 11. The surface of the connecting block 11 is penetrated by a long sliding slot 12. The connecting block 11 is sleeved on the outside of the connecting column 8 through the sliding slot 12. When the sliding component 9 slides horizontally, the inner wall of the sliding slot 12 squeezes the connecting column 8 to drive the connecting plate 7 and the limit baffle 6 to rotate around the connection between the limit baffle 6 and the pressure platform 5, thereby adjusting the inclination angle of the connecting plate 7. After the inclination angle of the connecting plate 7 is adjusted, it can remain stable and will not change due to the squeezing of the workpiece 3 to be processed.

[0039] Embodiment 2

[0040] On the basis of Example 1, in order to drive the sliding assembly 9 to slide horizontally, the driving stud 15 of the present application is fixedly installed at the output end of the driving motor 16, and the driving motor 16 is fixedly installed in the middle of the lower surface of the pressure platform 5. The outer thread of the driving stud 15 is sleeved with a threaded sleeve 14, and the outer side of the threaded sleeve 14 is fixedly connected with a strip plate 13, and the upper surface of the strip plate 13 is fixedly connected with a triangular bracket 10, and the connecting block 11 is fixedly installed on the upper end of the triangular bracket 10. When the driving motor 16 is working, it drives the threaded sleeve 14 to slide horizontally along its axial direction, thereby driving the sliding assembly 9 to slide horizontally as a whole.

[0041] Embodiment 3

[0042] On the basis of the second embodiment, in order to prevent the limit baffle 6 from being deformed due to excessive local force, the present application provides multiple connecting plates 7, triangular brackets 10 and connecting blocks 11, which are evenly spaced along the length direction of the strip plate 13. The multiple connecting plates 7 and the multiple connecting blocks 11 are distributed at intervals. The connecting plate 7 is arranged in a fan shape, and the center of the connecting plate 7 coincides with the upper end of the limit baffle 6. The multiple connecting plates 7 can provide stable support for the limit baffle 6, prevent the limit baffle 6 from being deformed due to excessive local force, and thereby improve the pressure-bearing effect of the limit baffle 6.

[0043] Embodiment 4

[0044] On the basis of the third embodiment, in order to fix the threaded sleeve 14 and the sliding assembly 9, the present application also has a reinforcing rod 17 arranged above the strip plate 13, and the reinforcing rod 17 fixes the multiple triangular brackets 10 together. The lower surface of the triangular bracket 10 and the surface of the strip plate 13 are provided with connecting holes 18. The triangular bracket 10 and the strip plate 13 are fixedly connected by bolts, thereby ensuring that the threaded sleeve 14 and the sliding assembly 9 remain relatively fixed, and when the threaded sleeve 14 moves, it can drive the sliding assembly 9 to move synchronously.

[0045] Embodiment 5

[0046] On the basis of Example 4, in order to install and connect the limit baffle 6, the present application also has an arc-shaped boss 2 that is the same as that on the conveying platform 1, which is arranged on the side of the pressure platform 5, and a rotating shaft hole 19 is opened inside the arc-shaped boss 2, and a notch groove 20 is opened on the inner wall of the rotating shaft hole 19 and extends to the outside of the arc-shaped boss 2. The upper end of the limit baffle 6 is provided with a matching boss 21 corresponding to the notch groove 20, and a rotating shaft body 22 is rotatably arranged in the inner cavity of the rotating shaft hole 19. The matching boss 21 extends to the inner cavity of the rotating shaft hole 19 and is fixedly connected to the rotating shaft body 22. The limit baffle 6 remains fixed with the rotating shaft body 22, and the rotating shaft body 22 can rotate in the rotating shaft hole 19. The matching boss 21 and the notch groove 20 can prevent the rotating shaft body 22 from moving along its own length direction, thereby ensuring that the limit baffle 6 can only rotate around the rotating shaft body 22 without displacement.

[0047] Embodiment 6

[0048] On the basis of Embodiment Five, in order to prevent the connecting plate 7 from colliding with the pressure-bearing platform 5, the present application further has a plurality of receiving grooves 23 arranged at equal intervals on both side surfaces of the pressure-bearing platform 5. The receiving grooves 23 correspond exactly to the connecting plate 7 and are used to receive the connecting plate 7 to prevent the connecting plate 7 from colliding with the pressure-bearing platform 5 when it rotates. A motor installation groove 24 for clamping and installing the driving motor 16 is provided in the middle of the lower surface of the pressure-bearing platform 5 for positioning the driving motor 16. A positioning hole 25 is provided on the lower surface of the pressure-bearing platform 5. The lower surface of the pressure-bearing platform 5 is fixedly connected by bolts with a bottom cover plate 26 covering the lower side of the driving motor 16 for protecting the driving motor 16.

[0049] Embodiment Seven

[0050] On the basis of Embodiment Six, in order to prevent the workpiece 3 to be processed from undergoing horizontal lateral displacement during transportation, the present application further has side clamping plates 27 provided on both sides at the front end of the transportation platform 1. The upper edge of the side clamping plate 27 is bent to form a clamping groove 28. The clamping groove 28 is horizontally buckled outside the edge of the workpiece 3 to be processed for limiting the horizontal lateral displacement of the workpiece 3 to be processed and preventing the position of the workpiece 3 to be processed from shifting. A telescopic cylinder 29 is fixedly connected to the side surface of the transportation platform 1. The movable end of the telescopic cylinder 29 is fixedly connected to the side clamping plate 27 for controlling the position of the side clamping plate 27.

[0051] Embodiment Eight

[0052] On the basis of Embodiment Seven, in order to perform a bending process on the workpiece 3 to be processed, the bending bracket 4 of the present application includes a "C"-shaped frame 41 with an opening facing downwards. Movable pressing plates 42 are rotatably installed at both ends of the "C"-shaped frame 41. A torsion spring for resetting is provided between the movable pressing plate 42 and the "C"-shaped frame 41, and the middle parts of the "C"-shaped frame 41 and the movable pressing plate 42 are rotatably connected. The movable pressing plate 42 presses down on the upper surface edge of the workpiece 3 to be processed. As Figure 8 shown, when the entire bending bracket 4 moves downward, the movable pressing plate 42 squeezes the edge of the upper surface of the workpiece 3 to be processed to perform a bending process on the workpiece 3 to be processed. Since the movable pressing plate 42 is integrally strip-shaped, when the movable pressing plate 42 squeezes the workpiece 3 to be processed, the force-bearing area of the workpiece 3 to be processed can be effectively increased, ensuring that the surface of the bent part of the workpiece 3 to be processed can remain flat and neat.

[0053] Embodiment Nine

[0054] On the basis of the eighth embodiment, in order to avoid the middle part of the workpiece 3 to be processed bulging during bending, the present application further has a limiting pressure plate 43 provided in the middle of the inner side of the "C"-shaped frame 41 and pressing on the middle part of the upper surface of the workpiece 3 to be processed. The upper surface of the limiting pressure plate 43 is fixedly connected with a movable column body 44. The upper end of the movable column body 44 is movably and penetratingly connected with the middle part of the "C"-shaped frame 41, and a limiting plate is fixedly connected to the upper end of the movable column body 44. A pressing spring 45 that is movably sleeved on the outside of the movable column body 44 is provided between the limiting pressure plate 43 and the "C"-shaped frame 41. The pressing spring 45 provides a thrust force to stably press the limiting pressure plate 43 on the middle part of the upper surface of the workpiece 3 to be processed, avoiding the middle part of the workpiece 3 to be processed from bulging upward due to the force on both sides during the bending process.

[0055] Embodiment Ten

[0056] On the basis of the ninth embodiment, in order to control the lifting of the bending bracket 4, the present application further has a connecting frame 46 fixedly connected to the middle part of the "C"-shaped frame 41. The upper surface of the connecting frame 46 is fixedly installed with a hydraulic telescopic rod 47. The upper end of the hydraulic telescopic rod 47 is installed on an external cross beam and is driven to expand and contract by a hydraulic controller. The hydraulic telescopic rod 47 is used to control the lifting of the bending bracket 4 to ensure that when the bending bracket 4 moves from top to bottom, it can press on the upper surface of the workpiece 3 to be processed to perform bending processing on the workpiece 3 to be processed.
