Description

Technical Field

[0001] This utility model relates to the field of pipe pile production technology, specifically a bending device for pipe pile production. Background Technology

[0002] Pipe piles are commonly used in building foundation engineering. The production process generally includes steps such as steel bar processing, mold installation, material placement, prestressing tension, centrifugal forming, steam curing, and demolding. The bending device is a key piece of equipment in the steel bar processing stage of pipe pile production. It is mainly used for spiral stirrup forming, steel bar end treatment, and precise bending of metal components to ensure the strength and connection reliability of the pipe pile structure.

[0003] According to Chinese Utility Model Application No. CN202421201419.9, a rebar bending device for construction is proposed. The utility model describes that "the rebar bending device, through the protective shell, when the rebar needs to be bent, places the rebar on the upper surface of the stop block, and activates the external hydraulic device. The power of the hydraulic device is transmitted to the hydraulic rod through the hydraulic sleeve. The hydraulic rod moves downward, pushing the protective device and the extrusion head downward, so that the extrusion head bends the surface of the rebar. As the bending angle of the rebar surface gradually increases, the protective device rotates, so that the surface of the protective shell fits more closely to the surface of the rebar. Thus, the V-shaped groove opened inside the protective shell can tightly clamp the rebar, preventing the rebar from breaking during excessive bending, thereby protecting the user."

[0004] The steel bar bending device for this building involves placing the steel bar on the upper surface of a stop block, with an extrusion head moving the steel bar downwards. The extrusion head, in conjunction with the stop block, bends the steel bar. However, the stop block is fixedly connected to the upper surface of the base plate, making it difficult to adjust the curvature of the steel bar bend. This limits the applicability of the steel bar and affects production efficiency, necessitating improvement. Therefore, a bending device for pipe pile production is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a bending device for pipe pile production, which has advantages such as easy adjustment of the bending arc of the reinforcing bars. This solves the problem that the difficulty in adjusting the bending arc of the reinforcing bars limits the applicable range of the reinforcing bars and affects the production effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bending device for pipe pile production, comprising a workbench, a hydraulic cylinder fixedly installed on the top of the workbench, a disassembly and assembly mechanism provided at the output end of the hydraulic cylinder, a bending head provided on the disassembly and assembly mechanism, an adjustment mechanism provided on the workbench, a limit mechanism provided on the adjustment mechanism, and a protective cover rotatably installed on the workbench;

[0007] The adjustment mechanism includes a chamber body, which is fixedly connected to the top of the workbench. A motor is fixedly installed on the outer wall of the chamber body.

A second threaded rod is fixedly installed on the side of the first threaded rod away from the motor. The thread direction of the first threaded rod is opposite to that of the second threaded rod. Threaded sleeves are threadedly installed on the outside of both the first and second threaded rods. The top of the threaded sleeve passes through the chamber body and is fixedly installed with an adjustment rod. An adjustment plate is fixedly installed on the top of the adjustment rod.

[0008] Furthermore, the side of the second threaded rod away from the first threaded rod is rotatably connected to the inner wall of the chamber via a bearing, and the length of the first threaded rod is equal to the length of the second threaded rod.

[0009] Furthermore, an adjustment hole is provided on the top of the compartment, and the adjustment hole is matched with the adjustment rod.

[0010] Furthermore, the disassembly and assembly mechanism includes a housing, which is fixedly connected to the output end of the hydraulic cylinder. The bending head penetrates and extends into the housing. A spring is fixedly installed on the inner wall of the housing. A movable plate is fixedly installed on the end of the spring away from the inner wall of the housing. A movable rod that penetrates the spring and the housing and extends to the outside of the housing is fixedly installed on one side of the movable plate. A movable block is fixedly installed on the side of the movable rod away from the movable plate. A positioning block that extends into the interior of the bending head is fixedly installed on the other side of the movable plate.

[0011] Furthermore, the limiting mechanism includes a limiting post, which is connected to the top of the adjusting plate by bolts and threads, and an annular plate is fixedly installed on the outside of the limiting post.

[0012] Furthermore, the protective cover is rotatably connected to the top of the workbench via a hinge, and the side wall of the protective cover has a through hole.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 In this embodiment, a bending device for pipe pile production includes a workbench 1. A hydraulic cylinder 2 is fixedly installed on the top of the workbench 1. A disassembly and assembly mechanism 3 is provided at the output end of the hydraulic cylinder 2. A bending head 4 is provided on the disassembly and assembly mechanism 3. An adjustment mechanism 5 is provided on the workbench 1. A limit mechanism 6 is provided on the adjustment mechanism 5. A protective cover 7 is rotatably installed on the workbench 1. An observation window 8 is embedded in the top of the protective cover 7. The observation window 8 is made of tempered glass and has an explosion-proof film on its surface.

[0023] Specifically, the workers first install a suitable bending head 4 on the disassembly and assembly mechanism 3, and a suitable limiting mechanism 6 on the adjustment mechanism 5. Then, the steel bar is placed on top of the limiting mechanism 6, and a protective cover 7 is used to shield the limiting mechanism 6. Finally, the hydraulic cylinder 2 is used to drive the disassembly and assembly mechanism 3 and the bending head 4 to move. The bending head 4 works with the limiting mechanism 6 to bend the steel bar. The protective cover 7 provides protection, and the curvature of the steel bar bend can be observed through the observation window 8. This not only facilitates the replacement of the bending head 4 and the limiting mechanism 6, but also facilitates the adjustment of the curvature of the steel bar bend, expanding the application range of the steel bar and improving production efficiency.

[0024] In this embodiment, the disassembly and assembly mechanism 3 includes a housing 31, which is fixedly connected to the output end of the hydraulic cylinder 2. The bending head 4 penetrates and extends into the housing 31. A spring 32 is fixedly installed on the inner wall of the housing 31. A movable plate 33 is fixedly installed on one end of the spring 32 away from the inner wall of the housing 31. A movable rod 34 is fixedly installed on one side of the movable plate 33, which penetrates the spring 32 and the housing 31 and extends to the outside of the housing 31. A movable block 35 is fixedly installed on the side of the movable rod 34 away from the movable plate 33. A positioning block 36 extending into the inside of the bending head 4 is fixedly installed on the other side of the movable plate 33.

[0025] Specifically, first, the moving block 35 is moved upward, which drives the moving rod 34, the moving plate 33, and the positioning block 36 to move upward. The spring 32 is compressed until the positioning block 36 is moved out of the inside of the bending head 4. Then, the bending head 4 is taken out of the inside of the housing 31, and the replaced bending head 4 is inserted into the inside of the housing 31. Finally, the moving block 35 is released, and the spring 32 returns to its original deformation, driving the moving plate 33 and the positioning block 36 to move downward. The positioning block 36 is then inserted into the inside of the bending head 4.

[0026] In this embodiment, the adjustment mechanism 5 includes a chamber 51, which is fixedly connected to the top of the workbench 1. A motor 52 is fixedly installed on the outer wall of the chamber 51. The output end of the motor 52 passes through the chamber 51 and is fixedly installed with a first threaded rod 53. A second threaded rod 54 is fixedly installed on the side of the first threaded rod 53 away from the motor 52. The thread direction of the first threaded rod 53 is opposite to that of the second threaded rod 54. The side of the second threaded rod 54 away from the first threaded rod 53 is rotatably connected to the inner wall of the chamber 51 through a bearing. The length of the first threaded rod 53 is equal to the length of the second threaded rod 54. Threaded sleeves 55 are threadedly installed on the outer sides of both the first threaded rod 53 and the second threaded rod 54. The top of the threaded sleeve 55 passes through the chamber 51 and is fixedly installed with an adjustment rod 56. An adjustment hole is opened on the top of the chamber 51, which matches the adjustment rod 56. An adjustment plate 57 is fixedly installed on the top of the adjustment rod 56.

[0027] Specifically, by turning on the motor 52, the motor 52 drives the first threaded rod 53 and the second threaded rod 54 to rotate, and the first threaded rod 53 and the second threaded rod 54 drive the two threaded sleeves 55, the two adjusting rods 56 and the two adjusting plates 57 to move relative to each other or in opposite directions.

[0028] In this embodiment, the limiting mechanism 6 includes a limiting post 61, which is connected to the top of the adjusting plate 57 by bolt thread, and an annular plate 62 is fixedly installed on the outside of the limiting post 61.

[0029] Specifically, the limiting post 61 can be removed by unscrewing the bolt from inside the adjusting plate 57, and the limiting post 61 can be installed by screwing the bolt into inside the adjusting plate 57. The reinforcing bar is placed on top of the annular plate 62.

[0030] In this embodiment, the protective cover 7 is rotatably connected to the top of the workbench 1 via a hinge, and the side wall of the protective cover 7 has a through hole.

[0031] Specifically, when the protective cover 7 is opened, the reinforcing bars can be placed directly on top of the annular plate 62. When the protective cover 7 is closed, the reinforcing bars can be placed on top of the annular plate 62 through the through hole. The protective cover 7 protects the workers.

[0032] The working principle of the above embodiments is as follows:

[0033] The operator first moves the moving block 35 upwards. The moving block 35 then moves the moving rod 34, moving plate 33, and positioning block 36 upwards to the designated position. The spring 32 is compressed, and the appropriate bending head 4 is inserted into the housing 31. The moving block 35 is then released, and the spring 32 returns to its original shape, causing the moving plate 33 and positioning block 36 to move downwards. The positioning block 36 is inserted into the bending head 4, and the bolt is screwed into the adjusting plate 57. The limiting post 61 can then be installed. The motor 52 is then turned on, causing the first threaded rod 53 and the second threaded rod 54 to rotate. Rod 53 and the second threaded rod 54 drive the two threaded sleeves 55, the two adjusting rods 56 and the two adjusting plates 57 to move relative to each other or in opposite directions to the designated position, and place the reinforcing bar on top of the annular plate 62. The protective cover 7 is rotated to shield the reinforcing bar, and then the hydraulic cylinder 2 is activated to drive the bending head 4 to move. The bending head 4, in conjunction with the limiting post 61, bends the reinforcing bar. The protective cover 7 provides protection, and the curvature of the bending reinforcing bar can be observed through the observation window 8. This not only facilitates the replacement of the bending head 4 and the limiting post 61, but also facilitates the adjustment of the curvature of the bending reinforcing bar, expanding the application range of the reinforcing bar and improving the production efficiency.
