Description

Technical Field

[0001] This utility model relates to the field of CNC bending machines, and in particular to a robotic arm CNC bending machine. Background Technology

[0002] A CNC bending machine is a metal sheet processing equipment based on computer numerical control (CNC) technology. It controls the hydraulic or servo system to drive the slider and mold through a preset program to achieve high-precision bending and forming of metal sheets. The robot arm is a key component of the automated bending unit and mainly undertakes tasks such as loading and unloading, positioning, follow-up bending and quality monitoring.

[0003] Chinese patent CN221312007U discloses a CNC bending machine with an integrated robotic arm. The robotic arm places the sheet metal on the upper surface of the placement plate using a suction cup, and then activates a second pneumatic cylinder to bend the sheet metal. During the bending process, the robotic arm can simultaneously grab the next sheet metal using the suction cup, thus greatly improving processing efficiency.

[0004] In the above scheme, the posture of the sheet is adjusted by a multi-axis robot, and then the sheet is moved to the placement plate. After that, the sheet is fixed on the placement plate by a cylinder. Finally, the sheet is bent on the placement plate and slides into the collection box. However, a single sheet often needs to be bent multiple times by adjusting its posture. In the above scheme, the sheet can only be bent once after its position is fixed, which is only suitable for single bending. There is a problem that the sheet cannot be continuously adjusted for bending posture, resulting in low bending efficiency. Therefore, a robot-assisted bending CNC bending machine is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a robotic arm bending CNC bending machine to solve the problem mentioned in the background art that the bending posture of the sheet metal cannot be continuously adjusted, resulting in low bending efficiency of the sheet metal. The technical solution of this utility model provides a solution that is significantly different from the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A robotic arm CNC bending machine includes a bending machine body, a steering mechanism for adjusting the bending posture of the plate body is provided on one side of the bending machine body, and a moving mechanism for moving the steering mechanism and the position of the plate body.

[0007] Preferably, the moving mechanism includes a base and a support, with a slide rail and a first lead screw on the top of the base, and a first motor on one side of the base, the first motor being connected to the first lead screw shaft.

[0008] Preferably, the lower end of the bracket is provided with a slider, the slider is mounted on a slide rail, the first lead screw is threadedly connected to the slider, the upper end of the bracket is provided with a second motor, the inside of the bracket is provided with a second lead screw, and the second motor is connected to the shaft of the second lead screw.

[0009] Preferably, the steering mechanism includes a load-bearing plate, a support rod, a connecting block, and a material support frame. One end of the load-bearing plate is threadedly connected to a second lead screw, and the other end of the load-bearing plate is connected to the support rod via a rotating shaft. The rotating shaft is connected to the load-bearing plate via a bearing. A third motor is provided on one side of the load-bearing plate and is connected to the rotating shaft.

[0010] Preferably, a fourth motor is provided at one end of the support rod, the fourth motor is connected to the connecting block through a coupling, the connecting block is connected to the material support frame through screws, and a suction cup is provided on the side of the material support frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a suction cup to fix the sheet body onto the support frame. A first motor controls one end of the sheet body to enter the bending machine body for bending. After bending at this end, the first motor moves the sheet body away from the bending machine body. A fourth and third motor work together to adjust the bending posture of the sheet body. Then, a second motor adjusts the height of the sheet body. Finally, the first motor controls the other end of the sheet body to enter the bending machine body for bending. These steps are repeated until the sheet body is bent, thus achieving continuous adjustment of the sheet body's posture and enabling continuous bending, thereby improving bending efficiency.

[0016] 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.

[0017] Please see Figure 1-3 In this utility model, a robotic arm bending CNC bending machine includes a bending machine body 1, a steering mechanism for adjusting the bending posture of a plate body 2 is provided on one side of the bending machine body 1, and a moving mechanism for moving the steering mechanism and the position of the plate body 2.

[0018] Example 1: Please refer to Figure 1-3In this embodiment of the utility model, a robotic arm bending CNC bending machine has a moving mechanism including a base 3 and a support 4. A slide rail 301 and a first lead screw 302 are provided on the top of the base 3. A first motor 303 is provided on one side of the base 3 and is connected to the shaft of the first lead screw 302. A slider 401 is provided at the lower end of the support 4 and is mounted on the slide rail 301. The first lead screw 302 is threadedly connected to the slider 401. A second motor 403 is provided at the upper end of the support 4 and a second lead screw 402 is provided inside the support 4. The second motor 403 is connected to the shaft of the second lead screw 402.

[0019] The steering mechanism includes a load-bearing plate 5, a support rod 6, a connecting block 7, and a material support frame 8. One end of the load-bearing plate 5 is threadedly connected to the second lead screw 402, and the other end of the load-bearing plate 5 is connected to the support rod 6 via a rotating shaft 601. The rotating shaft 601 is connected to the load-bearing plate 5 via a bearing. A third motor 602 is provided on one side of the load-bearing plate 5 and is connected to the rotating shaft 601. A fourth motor 702 is provided on one end of the support rod 6 and is connected to the connecting block 7 via a coupling 701. The connecting block 7 is connected to the material support frame 8 via screws. A suction cup 801 is provided on the side of the material support frame 8.

[0020] The first motor 303 controls the support 4 to move back and forth along the slide rail 301 by rotating the first lead screw 302. The second motor 403 controls the steering mechanism to move up and down by rotating the second lead screw 402. The third motor 602 drives the plate body 2 to rotate around the pivot 601 by rotating the support rod 6. The fourth motor 702 drives the plate body 2 and the material support frame 8 to rotate around the connecting block 7.

[0021] After the plate body 2 is fixed on the support frame 8 by the suction cup 801, the first motor 303 controls one end of the plate body 2 to enter the interior of the bending machine body 1 for bending. After this end is bent, the first motor 303 drives the plate body 2 away from the bending machine body 1. The fourth motor 702 and the third motor 602 work together to adjust the bending posture of the plate body 2. Then the second motor 403 adjusts the height of the plate body 2. Finally, the first motor 303 controls the other end of the plate body 2 to enter the interior of the bending machine body 1 for bending. The above steps are repeated until the bending of the plate body 2 is completed, thereby realizing continuous adjustment of the posture of the plate body 2 and thus realizing continuous bending of the plate body 2, improving bending efficiency.

[0022] Furthermore, when one end of the sheet body 2 is bent inside the bending machine body 1, the outer part of the sheet body 2 will be in a raised state. At this time, the support frame 8 changes its posture according to the raised angle of the sheet body 2, thereby supporting the outer part of the sheet body 2, avoiding the sheet body 2 from being deformed due to gravity, and improving the bending stability.

[0023] The working principle of this utility model is as follows: After the bending posture of the plate body 2 is adjusted by the cooperation of the fourth motor 702 and the third motor 602, the second motor 403 adjusts the height of the plate body 2. Finally, the first motor 303 controls one end of the plate body 2 to enter the interior of the bending machine body 1 for bending. After the bending at this end is completed, the first motor 303 drives the plate body 2 away from the bending machine body 1 and repeats the above steps until the bending of the plate body 2 is completed. This realizes the continuous adjustment of the posture of the plate body 2, thereby realizing the continuous bending of the plate body 2 and improving the bending efficiency.
