[0001] This utility model belongs to the technical field of steel plate bending equipment, and specifically relates to an automatic bending device for steel plate components. Background Technology

[0002] In the field of building construction, the ends of columnar concrete structures (such as concrete columns and piles) usually need to be fitted with hoops to enhance the integrity and shear resistance of the structure. These hoops are mostly made of rings by bending strip steel plates. Currently, they are mainly made by bending manually, which is difficult to process. During the bending process, the steel plate is prone to shift, resulting in deviation of the bending angle. Moreover, the processing efficiency is extremely low, making it difficult to meet the time requirements of large-scale building projects.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] like Figure 1-2 As shown, an automatic bending device for steel plate components includes a bending platform 1, a drive wheel 2, a guide groove 5, and a bending wheel 8. The platform of the bending platform 1 is supported by a steel plate, and four square steel support columns are provided at the bottom. The drive wheel 2 is mounted on the bending platform 1 via a longitudinal rotating shaft. The bending platform 1 is provided with a bearing seat corresponding to the rotating shaft. A drive mechanism 4 is provided on the bending platform 1. The drive mechanism 4 is connected to the drive wheel 2 and is used to drive the drive wheel to rotate around its longitudinal rotating shaft axis, providing power for the forward movement of the steel plate, so that the drive wheel 2 can rotate horizontally.

[0029] The guide groove 5 is located on the side of the bending platform 1. One end of it extends along the tangent of the drive wheel 2 to the outer periphery of the drive wheel 2 and is close to the outer periphery of the drive wheel 2. The steel plate to be bent is fed into the guide groove 5 and can be accurately guided to the working area of ​​the drive wheel 2.

[0030] The bending wheels 8 are located near the outer periphery of the driving wheel 2 and are assembled via a longitudinal rotating shaft. Multiple bending wheels 8 are arranged equidistantly along an arc. The starting point of the arc corresponding to each bending wheel 8 is close to the guide groove 5. That is, the starting point of the arc trajectory is set near the exit of the guide groove 5, which is the area where the steel plate just comes out of the guide groove 5 and begins to contact the driving wheel 2. The distance between the multiple bending wheels 8 and the driving wheel 2 gradually decreases from the corresponding arc starting point to the end point, thus forming a bending channel. This bending channel starts from the arc starting point and causes the steel plate to travel along the arc towards its end point. Since the distance between each bending wheel 8 and the outer circumferential surface of the driving wheel 2 gradually decreases, the steel plate is gradually pressed against the driving wheel 2 through the gradual change in distance, thereby achieving smooth and continuous plastic bending deformation, and finally forming the required bending angle and curvature.

[0031] In this embodiment, the cross-section of the guide groove 5 is U-shaped, thereby forming a constraint channel corresponding to the steel plate. The inner hole size of the channel matches the thickness and width of the steel plate to be bent, ensuring that the steel plate is effectively constrained during the feeding process, preventing skewing or twisting, and ensuring the accuracy of the bending start position.

[0032] In another optional embodiment, in order to further limit the steel plate to travel along the set path, a stepped platform 3 extending outward horizontally is provided on the lower edge of the outer wall of the drive wheel 2. The stepped platform 3 forms a support plane, which effectively supports the steel plate during bending, thereby preventing the steel plate from shifting downward. At the same time, the lower surface of the inner hole of the guide groove 5 and the upper surface of the stepped platform 3 are on the same horizontal plane, so that the steel plate can smoothly transition from the guide groove 5 to the stepped platform 3 of the drive wheel 2.

[0033] To improve the compactness of the device and ensure the limiting capability of the guide groove 5, a notch adapted to the outer contour of the drive wheel 2 is provided at the end of the guide groove 5 near the drive wheel 2. This notch allows the end of the guide groove 5 to be as close as possible to the drive wheel 2, ensuring the limiting capability on the steel plate conveying path. Furthermore, the outer wall of the guide groove 5 can also guide the steel plate, allowing it to pass through the bending wheel 8 multiple times, ensuring bending accuracy.

[0034] Furthermore, a ring-shaped limiting flange 9 is provided on the outer circumference of the bending wheel 8. From the start point to the end point of the arc corresponding to the bending wheel 8, the diameter of the limiting flange 9 gradually decreases to accommodate the varying distance between the bending wheel 8 and the driving wheel 2 at different positions. This limiting flange 9 should be tangent to the outer circumferential surface of the driving wheel 2 or maintain a very small gap. The lower surface of the limiting flange 9 is at the same vertical distance as the upper surface of the stepped platform 3 on the driving wheel 2, thus the limiting flange 9 and the stepped platform 3 together form a bending channel, preventing the steel plate from warping upwards or slipping laterally during bending, thereby improving bending stability and forming accuracy.

[0035] In this embodiment, mounting plates are provided on both sides of the guide groove 5, and mounting holes are opened on the mounting plates. The mounting plates are fixed to the bending platform 1 by bolts.

[0036] To enable the disassembly of the bent steel plate, the bending wheel 8 is mounted on the bending platform 1 via an adjustment mechanism. The adjustment mechanism includes a base 11, a slider 12, a wheel frame 10, and an adjustment bolt 13. The base 11 is fixedly mounted on the bending platform 1 and has a groove on it. The groove extends in the direction of the center of the drive wheel 2. The groove can be dovetail-shaped. The slider 12 is slidably mounted in the groove. The wheel frame 10 is fixedly connected to the slider 12. The front end of the wheel frame 10 has a cantilevered part corresponding to the drive wheel 2. The cantilevered part is rotatably connected to the bending wheel 8 via a longitudinal rotating shaft.

[0037] An adjusting bolt 13 is threaded onto the end of the base 11 away from the drive wheel 2. The end of the adjusting bolt 13 is rotatably connected to the slider 12 via a bearing or ball joint. By turning the adjusting bolt 13, the slider 12 can be pushed or pulled to move within the groove, thereby causing the bending wheel 8 to move closer to or further away from the drive wheel 2. This allows for precise adjustment of the working distance between the bending wheel 8 and the drive wheel 2 to achieve different bending rates.

[0038] In an optional embodiment, a gear ring 6 is coaxially fixed below the drive wheel 2, and the drive mechanism 4 engages the gear ring 6 via a drive gear 7. The drive mechanism 4 can be a motor working in conjunction with a reducer, with a drive gear 7 mounted on the output shaft of the reducer.

[0039] The multiple bending rollers 8 correspond to arc angles of 90°-120°. This angle range can effectively complete the bending of steel pipes, ensuring bending quality while facilitating the disassembly of the formed steel plates.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be within the scope of protection of the pending claims of the present utility model.
