Description

Technical Field

[0001] This utility model relates to the field of bending device technology, specifically a bending device for hollow ultra-thin wall profiles. Background Technology

[0002] A hollow ultra-thin-walled profile bending device refers to a piece of equipment or machine used to process hollow ultra-thin-walled profiles. This device is specifically designed to bend hollow profiles, characterized by its ability to handle thin-walled profiles, and is typically used in the manufacture of lightweight structures or components requiring specific shapes. Its working principle may involve controlling the bending of the profile at a certain curvature to meet engineering design or product requirements;

[0003] A search revealed that Chinese patent CN215032584U discloses a bending device for hollow ultra-thin wall profiles. The patent describes a technical solution that allows for convenient adjustment of the bending angle of the hollow ultra-thin wall profile by means of a baffle, a telescopic plate, a fourth telescopic rod, and a second groove, making the device relatively simple to operate.

[0004] In this solution, workers adjust the angle of the baffle by activating the telescopic plate to achieve different bending effects for hollow ultra-thin wall profiles. However, the telescopic plate usually lacks stability to support the baffle at a stable angle during bending operations. During angle adjustment, the baffle will experience slight movement or vibration due to the movement of the telescopic plate, resulting in angle instability and affecting the accuracy and consistency of bending. Relying on the telescopic plate for support and angle adjustment can lead to damage or deformation of the telescopic plate due to insufficient material strength and design, thus affecting the long-term use and reliability of the equipment. To solve this technical problem, this utility model proposes a hollow ultra-thin wall profile bending device. Summary of the Invention

Relying on the telescopic plate for support and angle adjustment can lead to damage or deformation of the telescopic plate due to insufficient material strength and design, thus affecting the long-term use and reliability of the equipment. To solve this technical problem, this utility model proposes a hollow ultra-thin wall profile bending device.

[0009] The adjustment mechanism includes a dual-head motor and a pair of baffles. The dual-head motor is fixedly connected to the bottom of the worktable. Both output ends of the dual-head motor are fixedly connected to threaded rods, and the other end of the threaded rods is rotatably connected to the inside of the second fixed plate. Connecting blocks are threadedly connected to the outer walls of the threaded rods on both sides. Positioning plates are fixedly connected to the outer walls of the connecting blocks on both sides. A positioning rod is fixedly connected between the two fixed plates, and the positioning plate is slidably connected to the outer wall of the positioning rod. Support plates are fixedly connected to the outer walls of the positioning plates on both sides. Limiting block one is fixedly connected to the top of the other end of the support plate. A rotating plate is rotatably connected inside the limiting block one. Limiting block two is rotatably connected to the other end of the rotating plate, and baffles are fixedly connected to the outer wall of the limiting block two. The bottom ends of the baffles are located on both sides of the abutment block.

[0010] Preferably, a limiting ring is fixedly connected to the bottom end of the baffle, and a pair of vertical plates are fixedly connected to both sides of the top of the workbench. An inner rod is fixedly connected between the two vertical plates, and the limiting ring is rotatably connected to the outer wall of the inner rod.

[0011] Preferably, a pair of grooves are provided on both sides of the workbench, and the grooves correspond to the rotating plate, with the rotating plate slidably connected in the grooves.

[0012] Preferably, the worktable has an inner groove on both sides, and a pair of electric push rods are provided at both ends of the worktable.

[0015] (III) Beneficial Effects

[0016] This utility model provides a bending device for hollow ultra-thin wall profiles. It has the following beneficial effects:

[0017] (1) Driven by a double-headed motor at the bottom of the workbench, the threaded rods at both ends rotate, causing the connecting block to move left and right with the rotation of the threaded rods. The movement of the connecting block drives the positioning plate to move stably along the positioning rod direction. At the same time, the support plate follows the movement of the positioning plate to adjust the position of the rotating plate on the first limit block, thereby controlling the angle of the baffle on the second limit block. The baffle is fixed to the inner rod by the limit ring, so that it can accurately rotate around the inner rod. The rotating plate slides in the groove to ensure smooth movement and avoid jamming. These mechanisms work in coordination to effectively achieve precise angle adjustment when bending hollow ultra-thin wall profiles on the contact block. This solves the problem of inaccuracy and instability caused by direct adjustment by the telescopic plate in traditional equipment, making the bending equipment more flexible and efficient to operate.

[0018] (2) According to the width of the profile, operate the electric push rod in the inner groove to push the electric telescopic rod to move left and right. Under the restriction of the limit frame, the electric telescopic rod moves stably in the slide groove to ensure that the distance between the two electric telescopic rods is completely matched with the width of the profile. According to the height of the profile placed on the abutment block, adjust the electric telescopic rod to push the positioning block to move up and down to ensure that the positioning block and the profile are perfectly aligned. This coordinated operation ensures fast and accurate positioning and effectively avoids the problem of sliding offset during bending. Attached Figure Description

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] Example 1: A hollow ultra-thin wall profile bending device includes a worktable 1. A contact block 2 is fixedly connected to the top of the worktable 1. Two pairs of fixing plates 3 are fixedly connected to the bottom of the worktable 1. A pair of fixing plates 4 are fixedly connected to the bottom of the worktable 1. An adjustment mechanism 5 is fixedly connected to the bottom of the worktable 1. The adjustment mechanism 5 includes a dual-head motor 501 and a pair of baffles 510. The dual-head motor 501 is fixedly connected to the bottom of the worktable 1. Threaded rods 502 are fixedly connected to both output ends of the dual-head motor 501. The other end of the threaded rods 502 is rotatably connected to the inside of the fixing plates 4. Connecting blocks 503 are threadedly connected to the outer walls of the threaded rods 502 on both sides. Positioning plates 504 are fixedly connected to the outer walls of the connecting blocks 503 on both sides. Positioning rods 505 are fixedly connected between the two fixing plates 3 on both sides, and the positioning plates 504 are slidably connected to the outer walls of the positioning rods 505. Support plates 506 are fixedly connected to the outer walls of the positioning plates 504 on both sides. A limit switch is fixedly connected to the top of the other end of the support plate 506. Block 1 507, a rotating plate 508 is rotatably connected inside the limiting block 1 507, and a limiting block 2 509 is rotatably connected to the other end of the rotating plate 508. A baffle 510 is fixedly connected to the outer wall of the limiting block 2 509. At the same time, the bottom end of the baffle 510 is set on both sides of the contact block 2. A limiting ring 511 is fixedly connected to the bottom end of the baffle 510. At the same time, a pair of vertical plates 512 are fixedly connected to both sides of the top of the worktable 1. An inner rod 513 is fixedly connected between the two vertical plates 512. At the same time, the limiting ring 511 is rotatably connected to the outer wall of the inner rod 513. A pair of grooves 6 are opened on both sides of the worktable 1. The grooves 6 correspond to the rotating plate 508, and the rotating plate 508 is slidably connected in the grooves 6.

[0027] The bending angle of the hollow ultra-thin wall profile is adjusted by activating the dual-head motor 501 at the bottom of the worktable 1. The dual-head motor 501 drives the threaded rods 502 at both ends to rotate. The threaded rods 502 are supported by the second fixed plate 4, which drives the connecting block 503 to move left and right. The movement of the connecting block 503 causes the positioning plate 504 to move left and right. The positioning plate 504 is constrained by the positioning rod 505 to ensure consistent movement direction. The movement of the positioning plate 504 further pushes the support plate 506 to move left and right. The movement of the support plate 506 affects the rotating plate 508 on the first limit block 507, causing the rotating plate 508 to push the baffle 510 on the second limit block 509 for angle adjustment. The baffle 510 rotates around the inner rod 513 at a fixed point, and its bottom end is constrained on the inner rod 513 by the limit ring 511. The rotating plate 508 slides in the groove 6 during movement to prevent jamming. Through the coordinated operation of these mechanisms, precise angle adjustment is achieved during the bending process of the hollow ultra-thin wall profile on the contact block 2, making the bending equipment more flexible and efficient.

[0028] Example 2: The difference between this example and Example 1 is that, in this example, the workbench 1 has an inner groove 7 on both sides, and a pair of electric push rods 8 are provided at both ends of the workbench 1. The electric push rods 8 are fixedly connected to the inner grooves 7, and the output end of the electric push rods 8 is fixedly connected to an electric telescopic rod 9. The electric telescopic rod 9 is slidably connected to the inner grooves 7. A pair of sliding grooves 11 are provided inside the workbench 1, and a pair of limiting frames 10 are fixedly connected to the outer wall of the electric telescopic rod 9. The sliding grooves 11 correspond to the limiting frames 10, and the limiting frames 10 are slidably connected to the sliding grooves 11. A positioning block 12 is fixedly connected to the output end of the electric telescopic rod 9. A bracket 13 is fixedly connected to the top of the workbench 1, and a hydraulic rod 14 is fixedly connected to the top of the bracket 13. A pressure block 15 is fixedly connected to the output end of the hydraulic rod 14, and a pair of limiting rods 16 are fixedly connected to the top of the pressure block 15. A pair of fixing blocks 17 are fixedly connected to the upper outer wall of the bracket 13, and the limiting rods 16 are slidably connected to the fixing blocks 17.

[0029] In this device, a hollow ultra-thin wall profile is first placed on the contact block 2. Based on the profile's width, the electric push rod 8 in the inner groove 7 is activated, pushing the electric telescopic rod 9 to move left and right. The electric telescopic rod 9 is limited within the slide groove 11 by the limiting bracket 10, ensuring consistent movement direction. Thus, the distance between the electric telescopic rods 9 on both sides matches the profile width. Simultaneously, based on the profile's height position on the contact block 2, the positioning block 12 is moved up and down by activating the electric telescopic rod 9, ensuring precise alignment with the profile's position. This coordinated operation ensures rapid and accurate positioning of the profile during bending, effectively preventing slippage and offset. The hydraulic rod 14 at the top of the bracket 13 is then activated, pushing the pressure block 15 downwards, where it is restrained within the fixed block 17 by the limiting rod 16 during movement.

[0030] Working principle: When workers need to bend the hollow ultra-thin wall profile, they first place the profile on the contact block 2. Based on the profile's width, they activate the electric push rod 8 inside the inner groove 7. The electric push rod 8 then drives the electric telescopic rod 9 to move left and right. The electric telescopic rod 9 is limited within the slide groove 11 by the limit bracket 10, ensuring that the direction of movement of the electric telescopic rod 9 remains consistent. This ensures that the distance between the two electric telescopic rods 9 matches the profile width. Then, based on the height of the profile placed on the contact block 2, the electric push rod 8 is activated... The telescopic rod 9 pushes the positioning block 12 up and down to ensure it matches the profile position. Through their cooperation, a rapid positioning effect is achieved, avoiding slippage during bending. After positioning, according to customer requirements, the hydraulic rod 14 at the top of the bracket 13 is activated first. Under the action of the hydraulic rod 14, the pressure block 15 is pushed down. When the pressure block 15 moves down, it is limited within the fixed block 17 by the limiting rod 16. To determine the required bending angle for the hollow ultra-thin wall profile, the dual-head motor 501 at the bottom of the worktable 1 is activated. Under the action of 01, the threaded rods 502 at both ends rotate. Simultaneously, the threaded rods 502 are supported by the fixed plate 4 during rotation. The rotation of the threaded rods 502 causes the connecting blocks 503 at both ends to move left and right. The movement of the connecting blocks 503 causes the positioning plate 504 to move left and right, while simultaneously limiting its movement on the positioning rod 505, ensuring that the positioning plate 504 moves in the same direction. The movement of the positioning plate 504 causes a pair of support plates 506 to move left and right. The movement of the support plates 506 causes the rotating plate 508 on the limiting block 507 to move left and right, and the rotating plate 508... The moving plate 508 pushes the baffle 510 on the limiting block 2 509 to rotate, thereby adjusting the angle of the baffle 510. When the baffle 510 rotates, its bottom end is limited to the inner rod 513 by the limiting ring 511, so that the baffle 510 rotates around the inner rod 513 at a fixed point. At the same time, the rotating plate 508 slides in the groove 6 when moving left and right, preventing the rotating plate 508 from getting stuck when moving. Through their cooperation, the angle of the profile on the contact block 2 can be adjusted when bending, making the bending equipment more flexible and practical and improving work efficiency.
