[0023] This application provides a material stop device for a bending machine, effectively solving the problems of traditional bending machine material stop devices, which have simple structures, limited adjustment methods, difficulty in accurately positioning workpieces of different sizes in the length and width directions, and narrow applicability. In the length direction, this bending machine material stop device uses an electric telescopic rod to push a slider along a groove, guided and limited by a limiting rod, to achieve precise positioning of the first stop and prevent workpiece displacement in the length direction. In the width direction, a motor drives a gear to rotate, and using the height difference between two racks, drives the second stop to move in opposite directions, precisely adjusting the spacing to prevent workpiece displacement in the width direction.

The adjustment of each component is driven by motors and electric telescopic rods, making operation simple. Operators only need to activate the corresponding drive device according to the workpiece dimensions to quickly adjust the baffle positions, greatly reducing operational difficulty, labor intensity, and processing auxiliary time, thus improving overall production efficiency.
[0024] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application effectively solves the technical problem that traditional material-stopping devices used in bending machines have simple structures, limited adjustment methods, difficulty in accurately positioning workpieces of different sizes in the length and width directions, and a narrow range of applications. The overall idea is as follows:
[0025] To address the problems existing in the prior art, this utility model provides a material-stopping device for a bending machine, including a bending table 1. A bending groove 11 is formed in the middle of the upper surface of the bending table 1. A support 2 is set above the bending table 1, and a hydraulic cylinder 21 is fixedly installed on the support 2. A pressure block 22 is fixedly connected to the bottom end of the telescopic rod of the hydraulic cylinder 21. The pressure block 22 is located directly above the bending groove 11. Connecting plates 12 are fixedly connected to both ends of the bending table 1. The two connecting plates 12 are distributed along the length direction of the bending table 1. A baffle 4 is set above each connecting plate 12. A slider 41 is fixedly connected to the bottom end of each baffle 4. Electric telescopic rods 3 are fixedly installed on both ends of the bending table 1. The telescopic rod 2 of each electric telescopic rod 3 is fixedly connected to the slider 41. Baffles 2 5 are set on both sides of the upper end of the bending table 1. The two baffles 2 5 are arranged along the width of the bending table 1. The bracket 2 is distributed in a 2-degree direction. The two sides of the bottom end of the bracket 2 are fixedly connected to two connecting plates 12 respectively. The two sides of the upper end of the pressure block 22 are fixedly connected to guide rods 23. Each guide rod 23 moves through the bracket 2. The upper surface of each connecting plate 12 is provided with a sliding groove. Each sliding groove is fixedly installed with a limit rod 13. Each slider 41 moves through the sliding groove. Each limit rod 13 moves through the slider 41. The bottom end of each baffle 2 5 is fixedly connected to a sliding rod 51. The two sliding rods 51 are slidably installed in the bending table 1. The bending table 1 is fixedly installed with a motor 6. The output shaft of the motor 6 is fixedly connected to a connecting shaft 61. A gear 62 is fixedly installed on the connecting shaft 61. The connecting shaft 61 is rotatably installed in the bending table 1. The two sliding rods 51 are fixedly connected to racks 52. There is a height difference between the two racks 52. The gear 62 meshes with the two racks 52 respectively.
[0026] The workpiece to be bent is placed on the bending table 1 and positioned above the bending groove 11. At this time, the hydraulic cylinder 21 is in the initial retracted state, and the pressure block 22 is in a higher position and does not contact the workpiece. Under the action of the electric telescopic rod 3, the two baffles 4 can be moved to the appropriate position along the slide groove on the connecting plate 12 by the slider 41 according to the length requirements of the workpiece. The limiting rod 13 plays a guiding and limiting role, ensuring that the slider 41 can only move in a straight line in the slide groove, thereby accurately positioning the position of the baffles 4 to limit the workpiece placed along the length direction of the bending table 1. The initial position of the two baffles 5 can be adjusted according to the width requirements of the workpiece. The motor 6 is in the off state, and the two racks 52 and gears 62 are meshed but stationary. The slide rod 51 can slide in the bending table 1, so that the baffles 5 can move in the width direction of the bending table 1 to adapt to workpieces of different widths.
[0027] Based on the length of the workpiece to be bent, the electric telescopic rod 3 is activated. The telescopic rod 2 of the electric telescopic rod 3 extends or retracts, causing the slider 41 to slide within the groove. Since the slider 41 is fixedly connected to the baffle 4, the baffle 4 moves accordingly, thereby adjusting the distance between the two baffles 4 to perfectly match the length of the workpiece. This positions the workpiece along the length of the bending table 1, preventing displacement in the length direction. Based on the width of the workpiece to be bent, the motor 6 is activated. The output shaft of the motor 6 drives the connecting shaft 61 to rotate, and the gear 62 on the connecting shaft 61 rotates accordingly. Since gear 62 meshes with two racks 52 respectively, and the two racks 52 are fixed on two slide rods 51 respectively, and the slide rods 51 are fixedly connected to the baffle 2 5, when gear 62 rotates, it will drive the two racks 52 to move synchronously. Since there is a height difference between the two racks 52, the two baffles 2 5 can move towards or away from each other at different speeds during the movement, thereby accurately adjusting the distance between the two baffles 2 5 to match the width of the workpiece, positioning the workpiece in the width direction of the bending table 1, and preventing the workpiece from shifting in the width direction.
[0028] Once the workpiece is precisely positioned in both length and width directions, the hydraulic cylinder 21 is activated. The telescopic rod of the hydraulic cylinder 21 extends, pushing the pressure block 22 downward along the guide rod 23. The guide rod 23 moves through the bracket 2, serving as a guide to ensure that the pressure block 22 moves vertically downward, precisely applying pressure to the workpiece located above the bending groove 11, causing the workpiece to bend and deform at the bending groove 11, thus completing the bending operation.
[0029] Working principle:
[0030] The first step is to place the workpiece to be bent on the bending table 1, positioning it at a suitable position above the bending groove 11. At this time, the hydraulic cylinder 21 is in its initial retracted state, and the pressure block 22 is in a higher position, not in contact with the workpiece. Under the action of the electric telescopic rod 3, the two baffles 4 can be moved to a suitable position along the slide groove on the connecting plate 12 by the slider 41 according to the workpiece length requirements. The limiting rod 13 plays a guiding and limiting role, ensuring that the slider 41 can only move in a straight line within the slide groove, thereby accurately positioning the position of the baffles 4 to limit the workpiece placed along the length direction of the bending table 1. The initial position of the two baffles 5 can be adjusted according to the workpiece width requirements. The motor 6 is in an off state, and the two racks 52 and gears 62 are meshed but stationary. The slide rod 51 can slide within the bending table 1, allowing the baffles 5 to move in the width direction of the bending table 1 to accommodate workpieces of different widths.
[0031] The second step involves starting the electric telescopic rod 3 according to the length of the workpiece to be bent. The telescopic rod 3 extends or retracts, causing the slider 41 to slide within the groove. Since the slider 41 is fixedly connected to the baffle 4, the baffle 4 moves accordingly, adjusting the distance between the two baffles 4 to perfectly match the workpiece length. This positions the workpiece along the length of the bending table 1, preventing displacement. Then, based on the width of the workpiece to be bent, the motor 6 is started. The output shaft of the motor 6 drives the connecting shaft 61 to rotate, causing the gear 62 on the connecting shaft 61 to rotate accordingly. When the gear 62 rotates, it will drive the two racks 52 to move synchronously. Since the gear 62 meshes with the two racks 52 respectively, and the two racks 52 are fixed on the two slide rods 51 respectively, and the slide rods 51 are fixedly connected to the baffle 2 5, when the gear 62 rotates, it will drive the two racks 52 to move synchronously. Since there is a height difference between the two racks 52, the two baffles 2 5 can move towards or away from each other at different speeds during the movement, thereby accurately adjusting the distance between the two baffles 2 5 to match the width of the workpiece, positioning the workpiece in the width direction of the bending table 1, and preventing the workpiece from being displaced in the width direction.
[0032] Third, after the workpiece is accurately positioned in both length and width directions, the hydraulic cylinder 21 is activated. The telescopic rod of the hydraulic cylinder 21 extends and pushes the pressure block 22 downward along the guide rod 23. The guide rod 23 moves through the bracket 2 and acts as a guide to ensure that the pressure block 22 moves vertically downward and accurately applies pressure to the workpiece located above the bending groove 11, causing the workpiece to bend and deform at the bending groove 11, thus completing the bending operation.
[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
