[0027] To better explain and facilitate understanding of this application, a detailed description of the application is provided below with reference to the accompanying drawings and specific embodiments. The directional terms "front," "rear," "up," "down," "left," and "right" mentioned herein are used in conjunction with... Figure 1The orientation is used as a reference. The position of the loading lifting vehicle 8 relative to the front feeding mechanism 2 is defined as "front", and the front-back direction is defined as longitudinal; the position of the loading gantry robot 1 relative to the front feeding mechanism 2 is defined as "up"; the position of the front feeding mechanism 2 relative to the unloading roller conveyor line 5 is defined as "left", and the left-right direction is defined as transverse.

[0028] As mentioned above, current automated bending workstations in the industry still have shortcomings in terms of operability, flexibility, and space. Furthermore, most automated bending workstations are small and cannot meet the demands of heavy-duty bending. This is especially true in the engineering equipment manufacturing industry, where workpieces often weigh over one ton; current automated bending workstations cannot meet the needs of automatically bending heavier workpieces. Figure 6 The diagram shows a bending workpiece. Due to the large size of the workpiece to be bent, weighing up to 1.3 tons, a crane needs to be manually operated to continuously lift the workpiece and work in conjunction with the bending machine for bending. Furthermore, a single workpiece often requires 10-15 bends to meet the forming requirements. Therefore, in traditional bending operations, each bending machine needs to be equipped with an operator. For larger and heavier workpieces, two or even three people are needed to complete the bending operation, resulting in high labor costs. In addition, manual operation cannot be carried out for long periods of time, as personnel are prone to fatigue, and the operation is inherently dangerous, posing a risk of workplace injury, and it is impossible to guarantee the quality and consistency of the workpiece.

[0029] To address at least one of the technical problems existing in the prior art or related technologies, this application provides a heavy-duty automatic bending workstation, comprising: a loading gantry robot arm disposed above a front feeding mechanism; the front feeding mechanism and the rear feeding mechanism arranged side by side, the rear feeding mechanism being used to cooperate with the front feeding mechanism to adjust the workpiece position and maintain stability during bending; a bending mechanism disposed between the front feeding mechanism and the rear feeding mechanism; a discharge roller conveyor line disposed side by side with the front feeding mechanism; and a discharge gantry robot arm disposed above the discharge roller conveyor line. Automatic loading and unloading operations are achieved through the loading and unloading gantry robots; the front feeding mechanism and the rear feeding mechanism cooperate to achieve precise workpiece position control and maintain stability during bending, enabling the bending mechanism to perform multiple automatic bends continuously, reducing the number of operators, achieving the goal of saving labor and reducing costs, significantly reducing the labor intensity of operators, improving bending quality, ensuring workpiece consistency, and enhancing product competitiveness.

[0030] The following description, with reference to the accompanying drawings, describes an engine hood support device according to some embodiments provided in this application.

[0031] See Figures 1 to 5This application provides a heavy-duty automatic bending workstation, comprising: a loading gantry robot 1, positioned above a front feeding mechanism 2; the front feeding mechanism 2 and the rear feeding mechanism 3 arranged side by side, the rear feeding mechanism 3 being used to cooperate with the front feeding mechanism 2 to adjust the workpiece position and maintain stability during bending; a bending mechanism 4, positioned between the front feeding mechanism 2 and the rear feeding mechanism 3; a discharge roller conveyor 5, arranged side by side with the front feeding mechanism 2; and a discharge gantry robot 6, positioned above the discharge roller conveyor 5.

[0032] The loading gantry robot 1 can move longitudinally along the front feeding mechanism 2 to pick up the workpiece to be bent from the initial position and place it precisely onto the front feeding mechanism 2.

[0033] The front feeding mechanism 2 and the rear feeding mechanism 3 are located in the same column longitudinally. For example, the rear feeding mechanism 3 is positioned behind the front feeding mechanism 2. The front feeding mechanism 2 is used to push the workpiece backward from its initial position, that is, towards the rear feeding mechanism 3, until it reaches the working range of the bending mechanism 4. The rear feeding mechanism 3 is used to push the workpiece forward, that is, towards the front feeding mechanism 2. In this way, the rear feeding mechanism 3 and the front feeding mechanism 2 work together to precisely adjust the position of the workpiece within the working area of ​​the bending mechanism 4. Furthermore, during the bending process, the rear feeding mechanism 3 and the front feeding mechanism 2 work together to ensure the stability of the workpiece during bending.

[0034] The bending mechanism 4 is used to perform bending operations, and performs precise bending processing on the workpiece according to the preset bending parameters.

[0035] The unloading roller conveyor 5 and the front feeding mechanism 2 are on the same horizontal row. For example, the unloading roller conveyor 5 is located on the right side of the front feeding mechanism 2. It is used to receive the workpiece after bending. After bending, the rear feeding mechanism 3 moves the workpiece forward to the front feeding mechanism 2. The front feeding mechanism 2 performs the unloading operation to move the workpiece to the unloading roller conveyor 5.

[0036] The unloading gantry robot 6 can move longitudinally along the unloading roller conveyor line 5 to pick up the bent workpiece from the unloading roller conveyor line 5 and place it into the finished product area.

[0037] In one illustrative embodiment, such as Figure 3 As shown, the loading gantry robot 1 includes: a gantry support 11, which is set on both sides of the front feeding mechanism 2; a first guide rail 12, which is set on the gantry support 11; a moving crossbeam 13, which is set on the first guide rail 12; a drive motor 14, which is set on the moving crossbeam 13; and a workpiece gripper 15, which is set below the moving crossbeam 13. The workpiece gripper 15 is equipped with an electromagnetic chuck and a vacuum chuck, which are arranged alternately.

[0038] The gantry support 11, serving as a supporting structure, is positioned on both longitudinal sides of the front feeding mechanism 2. It possesses excellent load-bearing capacity, capable of withstanding large loads and ensuring the stability of the overall structure. The first guide rail 12, located at the top of the gantry support 11, provides guidance and support for the moving beam 13. The low coefficient of friction between the guide rail and the moving components reduces energy loss and wear. The moving beam 13 moves horizontally along the first guide rail 12, enabling precise displacement control and allowing the workpiece to be transported quickly and accurately to the front feeding mechanism 2. The drive motor 14 is an AC servo motor with dual-sided drive, connected to the workpiece gripper 15 via a linear guide rail. Through gear and rack transmission, it drives the workpiece gripper 15 to reciprocate up and down. The workpiece gripper 15 is designed in a rectangular shape and employs a double-lifting arm structure, ensuring structural reliability regardless of workpiece size or off-center loading. An alternating combination of vacuum chucks and electromagnetic chucks is used. Larger workpieces are gripped using a combination of vacuum and electromagnetic chucks, while narrower workpieces can be gripped using only electromagnetic chucks. Furthermore, the electromagnetic chuck is a power-off retention type. In the event of a sudden power outage or gas outage, the electromagnetic chuck remains engaged, thus providing protection.

[0039] Furthermore, position sensors are installed at both the upper and lower ends of the workpiece gripper 15 to control the stroke, and the lifting stroke is adjusted according to the position of the lower front feeding mechanism 2. In addition, buffer pads are installed at both the upper and lower ends of the workpiece gripper 15 to ensure the safety of movement.

[0040] Furthermore, the structure of the unloading gantry robot 6 is the same as that of the loading gantry robot 1, and will not be described again here.

[0041] In one illustrative embodiment, such as Figure 4 As shown, the front feeding mechanism 2 includes: a first lead screw guide rail 22, which is mounted on the first frame 21; a front push head 23, which is mounted on the first lead screw guide rail 22; and a roller 24, which is mounted on the first frame 21. The roller 24 and the first lead screw guide rail 22 are arranged alternately.

[0042] The first frame 21 supports and secures other components, providing a stable support platform to ensure the stability and reliability of the front feeding mechanism 2. Multiple first lead screw guides 22 are arranged longitudinally in parallel to guide the front pusher head 23 to move precisely in the longitudinal direction. Driven by a servo motor, the front pusher head 23 can achieve a feeding and positioning accuracy of ±0.05mm, thus enabling precise pushing of the workpiece. The front pusher head 23 pushes the workpiece along a predetermined path. After the loading gantry robot 1 places the workpiece onto the first frame 21, the front pusher head 23 pushes the workpiece into the working area of ​​the bending mechanism 4. The roller 24 moves the workpiece laterally. Through the rotation of the roller 24, the workpiece can be smoothly moved from the front feeding mechanism 2 to the unloading roller conveyor line 5.

[0043] In one illustrative embodiment, the front feeding mechanism 2 further includes a first universal ball 25, disposed on the first frame 21, with the first universal ball 25 and roller 24 arranged alternately. The first universal ball 25 has the characteristic of flexible rolling, which can significantly reduce the frictional resistance of the workpiece during the conveying process, allowing the workpiece to slide more flexibly, reducing energy consumption, reducing wear, and improving the conveying efficiency of the workpiece; at the same time, the first universal ball 25 can also play a supporting role. When the workpiece is placed on the conveying surface composed of roller 24 and the first universal ball 25, the first universal ball 25 can fill the gap between roller 24, providing continuous and uniform support for the workpiece. Especially when the workpiece is heavy, the first universal ball 25 can distribute the pressure of the workpiece on the conveying surface, reduce the load on individual contact points, and help extend the service life of the equipment.

[0044] In one illustrative embodiment, an electromagnet is provided on the front push head 23. When the electromagnet is energized, it generates a magnetic field and attracts the workpiece. This attraction ensures that the workpiece will not slip or deviate during the pushing process, thereby improving the accuracy and stability of the pushing. At the same time, when it is necessary to pull the workpiece out of the bending mechanism 4, the electromagnet remains energized. Due to the attraction force of the electromagnet, the workpiece will be firmly attracted to the front push head 23 and pulled out.

[0045] In one illustrative embodiment, such as Figure 5 As shown, the rear feeding mechanism 3 includes: a second lead screw guide rail 32, which is mounted on the second frame 31; a rear push head 33, which is mounted on the second lead screw guide rail 32; and a material support module 34, which is mounted on the second frame 31. The material support module 34 is used to keep the workpiece stable during the bending process.

[0046] The second lead screw guide rail 32 is arranged on the same straight line as the first lead screw guide rail 22, and is used to guide the rear push head 33 to move precisely in the longitudinal direction. Driven by a servo motor, the rear push head 33 can achieve a feeding and positioning accuracy of ±0.05mm, thereby realizing precise pushing of the workpiece. The rear push head 33 is used to cooperate with the front push head 23 to precisely adjust the position of the workpiece. When the front push head 23 pushes the workpiece into the bending mechanism 4, the rear push head 33 cooperates with the front push head 23 to clamp the workpiece and move it backward, which can ensure that the workpiece is accurately placed in the working position of the bending mechanism 4 and reduce positioning errors. When the front push head 23 pulls the workpiece out of the bending mechanism 4, the rear push head 33 cooperates with the front push head 23 to clamp the workpiece and move it forward. Through the cooperation of the two push heads, the workpiece is better supported and fixed during the movement, reducing positioning errors caused by shaking or vibration.

[0047] The purpose of the material support module 34 is to prevent the center of gravity of the workpiece from deviating from the center of the bend during the bending process, which would cause the workpiece to shift.

[0048] In one illustrative embodiment, the material support module 34 includes: a horizontal shaft 341, mounted on the second frame 31; and a support plate 342, mounted on the horizontal shaft 341. The horizontal shaft 341 is driven by a cylinder. When the workpiece is bent, the horizontal shaft 341 drives the support plate 342, enabling the support plate 342 to accurately support the workpiece and stabilize it. During bending, the workpiece is subjected to significant pressure and deformation forces, which may cause it to shift or deform. The support plate 342, through precise control of the horizontal shaft 341, effectively prevents such shifting or deformation, ensuring that the workpiece maintains a stable position and shape during bending, thereby improving processing accuracy and product quality.

[0049] In one illustrative embodiment, the rear feeding mechanism 3 further includes a second universal ball joint 35, which is disposed on the second frame 31, and the second universal ball joint 35 is arranged alternately with the second lead screw guide rail 32. The function of the second universal ball joint 35 is the same as that of the first universal ball joint 25, and will not be described again here.

[0050] In one illustrative embodiment, the heavy-duty automatic bending workstation further includes: a smart camera 7, mounted on the loading gantry robot 1. Multiple smart cameras 7 can be installed to identify workpiece features. After identifying the workpiece, the smart camera 7 transmits the workpiece features, such as gripping the edge of a straight segment and analyzing and calculating the included angle, to the industrial control computer. The industrial control computer automatically calls the corresponding gripping and automatic bending parameters. When the upper die is pressed down to the preset position, a photo-taking trigger signal is issued, and the smart camera 7 immediately takes a picture, acquiring a cross-sectional image of the bent straight segment. Image processing software automatically detects the straight segment of the workpiece in the image and calculates the angle between the straight segment and the horizontal plane. The calculated angle is compared with the target value, the deviation is analyzed, and sent to the industrial control computer, which automatically calculates the compensation parameters for the next bend, achieving multi-pass automatic bending.

[0051] In one illustrative embodiment, the heavy-duty automatic bending workstation further includes: a loading elevator 8, arranged in parallel with the front feeding mechanism 2; and a finished product elevator 9, arranged in parallel with the unloading roller conveyor line 5.

[0052] The loading lift 8 and the front feeding mechanism 2 are in the same longitudinal column. For example, the loading lift 8 is located in front of the front feeding mechanism 2. The loading lift 8 is used for automatic loading, adopts a mobile design, has a rated load of 25 tons, a length of 6800mm, and a width of 2800mm. It can simultaneously place two types of workpieces with a width of less than 1200mm and meets the requirements for workpiece stacking. The platform of the loading lift 8 can accommodate workpieces of different specifications. The upper force-bearing surface adopts a double-separated plane structure, which can lift on a single plane or lift on both planes simultaneously. During operation, the loading lift 8 moves out of the truss area. After the incoming material is placed on the loading lift 8, it moves back under the truss to wait for the loading truss robot 1 to pick up the material for bending.

[0053] The finished product lifting vehicle 9 is located in front of the unloading roller conveyor line 5 and is used for automatic unloading. The structure of the finished product lifting vehicle 9 is the same as that of the loading lifting vehicle 8, and will not be described again here.
