Description

Technical Field

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

[0002] In the steel processing industry, steel bending is a key processing technology, widely used in many industries such as construction, machinery manufacturing, and automotive. In the construction industry, high-precision bent steel can ensure the stability and safety of building structures. In automobile manufacturing, high-precision bent parts with complex shapes are key to ensuring the performance and assembly accuracy of automotive parts.

[0003] In the early days, steel was mostly bent manually. Workers used manual bending machines, wrenches and other tools to apply external force to the steel to make it bend. This method was not only inefficient and slow, but the bending accuracy also depended entirely on the worker's experience. Different workers would operate the same machine and the bending angle, radius and other parameters would vary greatly, resulting in inconsistent product quality, a high defect rate and high labor intensity.

[0004] With industrial development, automated bending equipment is now widely used. Current automated bending equipment generally has a structure similar to that described in patent application CN202410155068.0, including a mounting plate. A rotating mechanism is fixedly connected to the upper surface of the mounting plate, and a clamping mechanism is fixedly connected to the upper surface of the rotating mechanism. A drive motor is fixedly connected to the upper surface of the mounting plate behind the rotating mechanism. A dialing disc is fixedly connected to the front end of the output shaft of the drive motor. A dialing post is integrally formed on the left side of the outer wall of the dialing disc. A cam is fixedly connected to the outer wall of the output shaft of the drive motor behind the dialing disc. A power controller is fixedly connected to the upper surface of the mounting plate to the right of the cam. However, this invention still requires frequent manual loading and unloading, reducing production efficiency and preventing large-scale production.

[0005] Therefore, this utility model proposes a bending device for steel production to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a bending device for steel production, which solves the problem in the prior art that the steel bending process requires frequent manual loading and unloading, which reduces production efficiency and prevents large-scale production.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] A bending device for steel production includes a frame, on which a feeding hopper, a pushing device, and a bending device are connected. Two guide plates are symmetrically arranged inside the feeding hopper, and the guide plates are slidably connected within the hopper. The tops of the guide plates are inclined. A threaded rod is threadedly connected to the side wall of the feeding hopper, and the threaded rod is rotatably connected to the guide plate. A pushing device is provided at the bottom of the feeding hopper, and the pushing device includes a feeding plate and a first cylinder. A feeding groove is formed on the feeding plate. The first cylinder pushes the feeding plate to slide below the feeding hopper, and the first cylinder is detachably connected to the feeding plate. A second cylinder is also connected to the frame and is located on one side of the feeding hopper. The piston rod end of the second cylinder is connected to a first push plate, which corresponds to the feeding trough. The bending device is located at the end of the first push plate and includes a moving plate, a bending head, and a first drive motor. The moving plate is slidably connected to the frame. A third cylinder is connected to the bottom of the frame. The piston rod of the third cylinder is connected to the moving plate. A bending head is rotatably connected to the moving plate. The bottom of the moving plate is connected to the first drive motor. The drive shaft of the first drive motor is coaxially connected to the bending head. A fourth cylinder is located on the side of the bending head away from the feeding trough. The piston rod end of the fourth cylinder is connected to a second push plate, which corresponds to the bending head.

[0009] By adopting the above technical solutions, automatic feeding and bending of steel can be achieved without manual intervention, greatly reducing manual operation, improving production efficiency, and providing a strong guarantee for large-scale production.

[0010] Furthermore, a positioning plate is provided between the bending device and the first push plate, and a positioning groove is provided on the positioning plate. The positioning plate is detachably connected to the frame.

[0011] By adopting the above technical solution, the steel can be accurately positioned to ensure that it is in the correct bending position.

[0012] Furthermore, a pressing plate is provided above the positioning plate, and the lower end of the pressing plate is connected to the piston rod of the fifth cylinder, which is connected to the bottom of the frame.

[0013] By adopting the above technical solution, the steel can be pressed tightly onto the positioning plate to prevent displacement during bending.

[0014] Furthermore, a scale is provided on the top of the feeding hopper corresponding to the guide plate, and a handwheel is connected to the end of the threaded rod.

[0015] By adopting the above technical solution, the adjustment distance of the guide plate can be accurately controlled to meet the feeding requirements of steel of different sizes.

[0016] Furthermore, the frame has a discharge port corresponding to the second push plate, and a receiving box is provided at the lower end of the frame corresponding to the discharge port.

[0017] By adopting the above technical solution, the steel falls through the discharge port into the corresponding receiving box at the lower end of the frame, thus completing the collection of the steel.

[0018] Furthermore, the side wall of the feeding hopper is connected to an observation window.

[0019] By adopting the above technical solution, the condition of the steel can be observed through the observation window on the side wall of the feeding hopper, and any unexpected situations can be dealt with in a timely manner to ensure the continuity of the equipment's operation.

[0020] Furthermore, the clamping surface of the bending head is connected to an anti-slip rubber pad.

[0021] By adopting the above technical solution, the anti-slip rubber pad increases the friction with the steel, avoids slipping, and ensures bending accuracy.

[0022] In summary, compared with the prior art, the beneficial effects of this utility model are as follows:

[0023] This invention simply requires placing the steel into the feeding hopper, and then precisely positioning the steel by adjusting the handwheel, eliminating the need for frequent manual adjustments and achieving automatic feeding. During the feeding stage, the first and second cylinders automatically complete the feeding and pushing operations. During the bending stage, the third cylinder, the first drive motor, and the fifth cylinder work together to automatically bend the steel. During the unloading stage, the fourth cylinder automatically pushes the finished steel. All of this requires no manual intervention, greatly reducing manual operation, improving production efficiency, and providing strong support for large-scale production. Attached Figure Description

[0033] A pushing device is provided at the bottom of the feeding hopper 2. The pushing device includes a feeding plate 8 and a first cylinder 9. A feeding groove 10 is provided on the feeding plate 8. The first cylinder 9 pushes the feeding plate 8 to slide under the feeding hopper 2.

The piston rod end of the second cylinder 11 is connected to a first push plate 12. The first push plate 12 corresponds to the feeding groove 10.

[0034] A bending device is located at the end of the first push plate 12. The bending device includes a moving plate 13, a bending head 14, and a first drive motor. The moving plate 13 is slidably connected to the frame 1. A third cylinder 15 is connected to the bottom of the frame 1. The piston rod of the third cylinder 15 is connected to the moving plate 13. The bending head 14 is rotatably connected to the moving plate 13. The first drive motor is connected to the bottom of the moving plate 13. The drive shaft of the first drive motor is coaxially connected to the bending head 14. An anti-slip rubber pad 16 is connected to the clamping surface of the bending head 14. A positioning plate 17 is provided between the bending device and the first push plate 12. A positioning groove 18 is provided on the positioning plate 17. The positioning plate 17 is detachably connected to the frame 1. A pressing plate 19 is provided above the positioning plate 17. The piston rod of a fifth cylinder 20 is connected to the lower end of the pressing plate 19. The fifth cylinder 20 is connected to the bottom of the frame 1.

[0035] A fourth cylinder 21 is provided on the side of the bending head 14 away from the feeding hopper 2. The piston rod end of the fourth cylinder 21 is connected to a second push plate 22, which corresponds to the bending head 14. A feeding port 23 is provided on the frame 1 corresponding to the second push plate 22, and a receiving box 24 is provided at the lower end of the frame 1 corresponding to the feeding port 23.

[0036] The working process of this utility model is as follows:

[0037] First, turn the handwheel 6 to rotate the threaded rod 4, which is threaded to the side wall of the feeding hopper 2. This causes the guide plate 3 to slide along the inner wall of the feeding hopper 2, adjusting its position according to the steel size. This provides initial positioning and guidance, ensuring the steel is in the feeding position. During the adjustment of the guide plate 3, the adjustment distance can be precisely controlled using the scale 5 on the top of the feeding hopper 2, meeting the feeding requirements of steel of different sizes. Then, the steel to be bent is placed into the feeding hopper 2. Simultaneously, the condition of the steel can be observed through the observation window 7 on the side wall of the feeding hopper 2. Any unexpected situations can be addressed promptly, ensuring the continuous operation of the device.

[0038] Then, the first cylinder 9 is activated, pushing the feeding plate 8 to slide along a preset path below the feeding barrel 2. The steel in the feeding barrel 2 then falls into the feeding trough 10. Next, the second cylinder 11 on one side of the feeding barrel 2 is activated, and the first push plate 12 at the end of the piston rod of the second cylinder 11 pushes the steel out of the feeding trough 10. The steel is then pushed to the positioning plate 17, where the positioning groove 18 precisely positions the steel, ensuring it is in the correct bending position. Then, the fifth cylinder 20 is activated, and the pressing plate 19 at the end of the piston rod of the fifth cylinder 20 presses down, pressing the steel firmly onto the positioning plate 17 to prevent displacement during bending.

[0039] Then the first drive motor starts, and the drive shaft is coaxially connected to the bending head 14. The bending head 14 rotates under the drive of the motor to bend the steel in the positioning groove 18. The anti-slip rubber pad 16 on the clamping surface of the bending head 14 increases the friction with the steel to avoid slippage and ensure bending accuracy.

[0040] Then, the third cylinder 15 pushes the moving plate 13, which is slidably connected to the frame 1, away from the positioning plate 17, thereby driving the bent steel away from the positioning plate 17. Then, the first drive motor starts and drives the bent steel to rotate. Then, the fourth cylinder 21 starts, and the second push plate 22 at the piston rod end of the fourth cylinder 21 pushes the steel toward the discharge port 23 on the frame 1. Then, the steel falls into the corresponding receiving box 24 at the lower end of the frame 1 through the discharge port 23.
