[0002] Steel bending is a crucial process in metal forming, widely used in building steel structures, machinery manufacturing, and automotive parts production. Traditional bending equipment typically employs a hydraulic drive system with fixed dies, resulting in low precision in bending angle control and cumbersome die replacement. Existing technologies suffer from inaccurate coordination between servo control and mechanical structure, leading to angle deviations, and lack intelligent feedback and adjustment mechanisms. Especially when processing long steel sections, manual feeding and positioning are inefficient, and insufficient workpiece springback compensation easily results in defective products. Furthermore, traditional equipment generally neglects the impact of thermal effects on material deformation during processing, and the rigid impact of the bending die can easily damage the steel surface.

[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] like Figure 1-3 As shown, this utility model provides a steel bending device, including a workbench 1, a bending mechanism 101 disposed on the workbench 1, and a support platform 2 located at the other end of the workbench 1. The bending mechanism 101 includes a bending head 104 that can move up and down and a servo motor 103 that drives the bending head 104. The workbench 1 is provided with a bending groove that cooperates with the bending head 104. The support platform 2 is provided with a support seat 201 for clamping steel.

[0023] In this embodiment, when steel needs to be bent, the steel is first placed on the automatic feeding mechanism 202 of the support platform 2. The drive assembly 204 in the automatic feeding mechanism 202 starts working, and the drive motor drives the lead screw to rotate. Since the drive rod 206 is connected to the lead screw through a thread, under the rotation of the lead screw, the drive rod 206 slides in the feed groove 205 in a set direction, thereby pushing the steel to move towards the bending mechanism 101 until the steel is accurately delivered to the support base 201 and clamped and fixed by the support base 201.

[0024] The support base 201 is connected to the drive motor via a lead screw, which is set along the length of the worktable 1. In the initial state, the drive motor drives the lead screw to rotate, adjusting the support base 201 to a suitable initial position according to the specifications of the steel to be bent and the bending requirements. Subsequently, the servo motor 103 starts, driving the bending head 104 to move downward. The modular bending die 102 at the bottom of the bending head 104 is fixed to the bending head 104 through an interlocking structure and locked by bolts to ensure the stability and reliability of the die during the bending process. When the bending head 104 moves downward, the bending die engages with the bending groove on the worktable 1, applying bending force to the steel, causing the steel to undergo plastic deformation at the bending groove, thus achieving bending.

[0025] The support base 201 is provided with an automatic feeding mechanism 202, which includes a feeding trough 205, a drive rod 206 slidably disposed in the feeding trough 205, and a drive assembly 204 for driving the drive rod 206. The support base 201 is also provided with an angle detection device 203, which includes a laser rangefinder and a processor. The laser rangefinder is used to detect the bending angle of the steel, and the processor is electrically connected to the controller and feeds back the angle data to adjust the position of the support base 201.

[0026] During the bending process, the angle detection device 203 plays a crucial role. The laser rangefinder detects the angle changes of the bent portion of the steel in real time and converts the detected distance data into an angle signal, which is then transmitted to the processor. The processor processes and analyzes the received angle signal and compares it with the preset target bending angle. If a deviation exists, the processor feeds the angle data back to the controller. Based on the received angle data, the controller issues control commands to the drive motor. The drive motor, via a lead screw, moves the support base 201 along the length of the worktable 1, adjusting the support position of the steel. This changes the stress state of the steel during bending, thereby precisely adjusting the bending angle until the preset bending angle requirement is achieved.

[0027] The automatic feeding mechanism 202 enables automatic steel conveying, eliminating the need for manual feeding, greatly improving feeding efficiency and safety, and reducing human error. The support base 201, with its position adjustable via a lead screw and drive motor, combined with real-time feedback from the angle detection device 203, can precisely adjust its position according to different bending requirements, ensuring the steel is under optimal stress during bending. This significantly improves the accuracy of the steel bending angle, meeting the demands of high-precision bending processes.

[0028] Furthermore, the bottom of the bending head 104 is detachably connected to a modular bending mold 102. The modular bending mold 102 is fixed to the bending head 104 through an interlocking structure and locked by bolts.

[0029] The bottom of the bending head 104 adopts a detachable modular bending die 102, which is connected to the bending head 104 through a fitting structure and bolt locking. This design makes die replacement more convenient and faster. When it is necessary to process bent steel of different shapes and specifications, only the corresponding modular die needs to be replaced. There is no need to make complex adjustments or replacements to the entire bending mechanism 101, which greatly improves the versatility and flexibility of the equipment and reduces the cost and time of die replacement.

[0030] Furthermore, the support base 201 is connected to the drive motor via a lead screw, which is arranged along the length of the worktable 1. The drive motor drives the lead screw to rotate in order to adjust the position of the support base 201.

[0031] Furthermore, the drive assembly 204 includes a drive motor, a lead screw, and a fixed base, and the drive rod 206 is connected to the lead screw via a thread.

[0032] Furthermore, protective soft plates are provided on both sides of the bending head 104. The protective soft plates are connected to the bending head 104 through buffer blocks. The height of the protective soft plates is adapted to the upward tilting height of the steel end after the bending head 104 is pressed down.

[0033] The elastic buffer layer 105 located on both sides of the bending groove on the upper surface of the worktable 1 is composed of a concave buffer plate and a buffer spring. The concave buffer plate is connected to the worktable 1 through the buffer spring. During the bending head 104 pressing down, when the steel comes into contact with the surface of the worktable 1, the elastic buffer layer 105 can effectively buffer the impact force between the steel and the worktable 1, reduce the vibration and wear of the worktable 1, and extend the service life of the worktable 1.

[0034] The protective soft plates and buffer blocks on both sides of the bending head 104 work together to effectively prevent the ends of the steel from warping upwards during the bending process and causing injury to the operator, thus improving the safety of the equipment. The elastic buffer layer 105 on the worktable 1 buffers the impact force when the steel is bent, reducing the vibration and wear of the worktable 1, extending the service life of the equipment, and also reducing noise during the processing, thus improving the working environment.

[0035] Furthermore, an elastic buffer layer 105 is provided on the upper surface of the workbench 1. The elastic buffer layer 105 is located on both sides of the bending groove. The elastic buffer layer 105 includes a concave buffer plate and a buffer spring. The concave buffer plate is connected to the workbench 1 through the buffer spring.

[0036] Furthermore, a temperature sensor is installed inside the bending head 104, and a controller is installed on the worktable 1. The temperature sensor is electrically connected to the controller, and the controller adjusts the output power of the servo motor 103 according to the detection data of the temperature sensor.

[0037] A temperature sensor installed inside the bending head 104 monitors the temperature changes of the bending head 104 in real time and transmits the temperature data to the controller. Based on the temperature sensor data, the controller adjusts the output power of the servo motor 103 in real time. When the temperature of the bending head 104 is too high, the controller automatically reduces the output power of the servo motor 103 to reduce the workload of the bending head 104 and decrease its heat generation; when the temperature is too low, the controller appropriately increases the output power of the servo motor 103 to ensure that the bending process is carried out within a suitable temperature range, avoiding any impact on bending quality and normal equipment operation due to abnormal temperatures.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
