The guide structure body 100 is also provided with: The mechanism facilitates disassembly and assembly, and includes a rotating connecting component located at the connection between the inner side of the top frame 103 and the bottom end of the bending base 101. A clamping and reinforcing component is provided at the top edge of the connection between the top frame 103 and the guide rod 102. A pressing and pushing component is provided on one side of the clamping and reinforcing component, and a rotating pressing component is provided at the top of the pressing and pushing component. When the bending pressure plate 105 is guided by the guide rod 102, the guide rod 102 can be disassembled and maintained through the convenient disassembly and assembly mechanism when maintenance is required after long-term use. The operation is simple and convenient.

[0015] To facilitate the fixed installation of the bottom end of the guide rod 102 to the upper surface of the bending base 101 via a rotary connection assembly, in this embodiment, preferably, the rotary connection assembly includes an internally threaded base 1021 welded and fixed to both ends of the upper surface of the bending base 101.

[0016] To facilitate the compression and reinforcement installation of the clamping block 1028 using the clamping and reinforcement assembly, in this embodiment, preferably, the clamping and reinforcement assembly includes four adjusting slots 1027 located inside the top frame 103 at the edge of the perforation 1023. The inner side of each adjusting slot 1027 limits the clamping block 1028. The surface of the clamping block 1028 has a beveled structure 10201. A compression groove 1029 is formed on the outer surface of the top end of the guide rod 102. The end surface of the clamping block 1028 presses against the inner surface of the pressing groove 1029, allowing the four clamping blocks 1028 to simultaneously press against the surface of the pressing groove 1029 for reinforcement and installation, facilitating fixed installation. A return spring 10202 is fixed at the connection between the bottom side of the clamping block 1028 and the bottom side of the adjusting groove 1027. During disassembly, the return spring 10202 can deform to reset the clamping block 1028 when it loses its pressing force.

[0017] To facilitate the compression and clamping of the reinforcing clamping block 1028 via the compression pushing assembly, in this embodiment, preferably, the compression pushing assembly includes an internal threaded groove 1025 formed on the upper surface of the top frame 103 at the edge of the through hole 1023. Four push rods slidably at the bottom of the internal threaded groove 1025. The bottom of each push rod 1020 is fixed with a compression push block 1026 inside the adjustment groove 1027. The surface of the compression push block 1026 is in compression contact with the surface of the inclined structure 10201. When the push rod 1020 moves the compression push block 1026 downward, the surface of the compression push block 1026 contacts the inclined structure 10201, causing the reinforcing clamping block 1028 to be compressed and clamped inside the compression groove 1029 for reinforcement and installation, facilitating reinforcement and installation, and conversely, facilitating disassembly.

[0018] In order to facilitate the simultaneous pressing and moving of the four push rods 1020 by means of the rotary clamping assembly, in this embodiment, preferably, the rotary clamping assembly includes an external threaded ring 1024 threaded inside the internal threaded groove 1025, and the upper surface of the external threaded ring 1024 is provided with internal hexagonal grooves at equal intervals. A wrench can be engaged inside the internal hexagonal groove to drive the external threaded ring 1024 to rotate inside the internal threaded groove 1025 to press and move the push rods 1020 downward.

[0019] The anti-friction rolling mechanism includes a limiting mounting component disposed inside the guide hole 104. The inner surface of the limiting mounting component is provided with a rolling component. When the bending pressure plate 105 moves, it can be guided between the guide hole 104 and the guide rod 102 by the anti-friction rolling mechanism to effectively prevent friction and ensure smooth guidance.

[0020] To facilitate the installation of the arc plate 1041 and the ball bearing 1042 using the limiting installation assembly and to provide convenient anti-friction treatment, in this embodiment, preferably, the limiting installation assembly includes two arc plates 1041 that are limited and closed inside the guide hole 104, and after the two arc plates 1041 are closed, a sliding hole is formed inside.

The arc plate 1041 can be fixedly installed inside the guide hole 104, and the arc plate 1041 is convenient to install and convenient to disassemble.

[0021] To facilitate friction prevention during guided sliding using the rolling assembly, in this embodiment, preferably, the rolling assembly includes a rolling groove 1043 formed at the inner edge of the arc-shaped plate 1041. A ball bearing 1042 rolls inside the rolling groove 1043, and the outer surface of the ball bearing 1042 contacts the surface of the guide rod 102. This allows the ball bearing 1042 to roll against the outer surface of the guide rod 102 and prevent friction when the bending pressure plate 105 is guided to slide on the outer surface of the guide rod 102, thus reducing friction resistance.

[0022] The working principle and usage process of this utility model: When using this kind of bending machine guide structure, the first step is to install it. The guide rod 102 can be extended to the surface of the bending base 101 by passing through the bottom end of the through hole 1023 and the guide hole 104. The guide rod 102 is rotated and fixed by the internal rotation of the external thread structure 1022 and the internal thread base 1021. After rotation and fixing, the external threaded ring 1024 is rotated at the top of the top frame 103 through the internal threaded groove 1025. When the external threaded ring 1024 rotates downward, the surface of the smooth push rod 1020 contacts the push rod 1020 and the pressing push block 1026 downward. When the pressing push block 1026 moves downward, the surface of the surface of the inclined structure 10201 presses and moves the reinforcing clamping block 1028 until the inner surface of the reinforcing clamping block 1028 is pressed and contacts the inside of the pressing groove 1029, clamping and fixing it, so that the guide rod 102 and the top frame 1023 are connected. The top of the 3 rotates once to clamp and reinforce the four reinforcing clamping blocks 1028, which is convenient for installation. After installation, if the bending pressure plate 105 is damaged due to bending after a long period of time and needs to be disassembled, replaced or repaired, the external threaded ring 1024 is loosened by rotating the return spring 10202. The return spring 102 deforms and drives the reinforcing clamping blocks 1028 to return to their original position. At this time, the guide rod 102 can be rotated for easy disassembly, which makes disassembly and assembly convenient and improves the convenience of disassembling and assembling the guide rod 102 when the guide structure body 100 is installed and used. Finally, the two arc-shaped plates 1041 are closed inside the guide hole 104 and fixedly installed. After the arc-shaped plates 1041 are fixed, the ball bearings 1042 contact the surface of the guide rod 102. When the bending pressure plate 105 bends, the ball bearings 1042 are guided and driven to contact the guide rod 102 on the outer surface of the guide rod 102, so that the ball bearings 1042 roll inside the rolling groove 1043, which makes the guide rod 102 roll smoothly and guide the process. It is not easy to generate friction damage, extend the service life, and is not easily obstructed, improving the convenience of anti-friction rolling when the guide structure body 100 is installed and used. Therefore, after installation, when the hydraulic cylinder drives the bending plate 105 to bend and move, the end of the bending plate 105 is guided and slid along the outer surface of the guide rod 102 through the guide hole 104 and the ball 1042 to control the bending process.
