Description

Technical Field

[0001] This utility model relates to the field of automatic feeding technology for bending machines, specifically to an automatic feeding structure for a hydraulic plate bending machine. Background Technology

[0002] In the manufacturing industry, many metal sheets require bending machines for bending to meet usage requirements. Most bending machines require manual feeding of the metal sheets into the bending mechanism, resulting in high labor intensity, low processing efficiency, and low precision. Some bending machines are equipped with feeding mechanisms, but during the feeding process, the sheets are prone to deviation, leading to feeding errors. Furthermore, the dimensions of each batch of sheets may vary, making it difficult for the feeding mechanism to meet usage requirements. Therefore, we propose an automatic feeding structure for hydraulic sheet metal bending machines.

[0003] To address the aforementioned technical problems, Chinese Patent No. CN216176044U discloses an automatic feeding structure for a hydraulic sheet metal bending machine. The structure includes a base, a lifting device connected to a pressure plate, a feeding seat fixedly connected to the upper end of the base via a second support rod, a rotating shaft extending through the feeding seat, a conveyor roller connected to the rotating shaft, an adjusting shaft movably connected to an adjusting seat, a belt connecting the adjusting shafts, an external thread on the adjusting shaft, an adjusting nut threaded onto the external thread, and a connecting rod passing through the space between two conveyor rollers with a stop block fixedly connected to its top.

[0004] While the aforementioned existing technical solutions can prevent the plate from deviating during the conveying process and ensure the accuracy of feeding, they use multiple sets of cylinders to drive the pressure plate to move. However, the compressibility of air causes a delay in the opening and closing of the cylinders, making it difficult for multiple sets of cylinders to respond completely synchronously. Moreover, after a period of use, the synchronization error will gradually increase, requiring frequent adjustments or replacements of cylinder components. Otherwise, the pressure plate may tilt and warp, causing twisting and deformation at the connection between it and the piston rods, or causing cylinder malfunctions. Furthermore, if the pressure plate is pressed down and adheres to the material surface, the friction between it and the material will interfere with the material's movement and conveying. If it is not adhered to the material surface, the material will still tilt and warp, and collide with the pressure plate, causing damage to the pressure plate or the material. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example: Please refer to Figures 1-4 This utility model provides a technical solution:

[0026] An automatic feeding structure for a hydraulic sheet metal bending machine includes a base 1. An extension plate is installed at one top end of the base 1, and a conveyor body 2 is installed at the other end of the extension plate. A threaded rod 3 is rotatably connected to one end of the inner side of the base 1, and a sliding rod 4 is installed at the other end of the inner wall of the base 1. A connecting frame is installed at the other top end of the base 1. A movable anti-tilting mechanism is installed on the connecting frame and the base 1. The movable anti-tilting mechanism includes a sliding component and an auxiliary conveying component. The sliding component is used to adjust the height of the auxiliary conveying component, which assists in conveying materials and prevents materials from tilting during conveying. In use, the height of the auxiliary conveying component can be adjusted by the sliding component. The auxiliary conveying component assists in conveying materials and prevents materials from tilting during conveying. The structure is simple and easy to operate. While preventing materials from tilting during conveying, it does not interfere with the material conveying process, allowing for stable conveying. The operation of adjusting the position of the auxiliary conveying component is convenient and time-saving, avoiding the situation where asynchronous operation when using a cylinder drive causes damage to parts and materials, further improving the practicality of the device.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, both ends of the top of the protective frame 21 are provided with push grooves that are slidably connected to the push plate 19. A spring damping shock absorber 22 is installed between the push groove and the inner wall of the push plate 19. Multiple sets of auxiliary rollers 23 are rotatably connected to the bottom end of the protective frame 21. The threads on both sides of the outer wall of the threaded rod 3 are opposite. Movable frames 24 are threadedly connected to both sides of the outer wall of the threaded rod 3. The movable frames 24 and the slide rod 4 are slidably connected. Multiple sets of guide rollers 25 are rotatably connected to one end of the opposite face of the two sets of movable frames 24. A motor is installed on one side of the outer wall of the base 1. The drive end of the motor extends... The material is first fed into the conveyor body 2 through one end of the threaded rod 3. Then, the motor can be started to drive the threaded rod 3 to rotate according to the width of the material being processed. This causes the movable frame 24 to move in opposite directions in conjunction with the slide bar 4. When the material is adjusted to the correct position and then conveyed, the guide roller 25 will contact the side surface of the material to limit its movement and prevent it from deviating. At the same time, the guide roller 25 can roll along with the conveyor body 2 to convey the material without hindering the material conveying.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the extraction assembly includes a movable column 5 installed at the bottom of the connecting frame. A movable sleeve 6 is slidably connected to the outer side of the movable column 5. A sliding groove is provided on one side of the outer wall of the movable column 5. A sliding block 7, which is slidably connected to the sliding groove, is installed on one side of the inner wall of the movable sleeve 6. Both the sliding groove and the sliding block 7 have a T-shaped cross-section. A fixed plate 8 is installed on one side of the outer wall of the movable sleeve 6. A movable disc 9 is rotatably connected to the center of one side of the outer wall of the fixed plate 8. A vertical rod 10 is installed on one side of the movable disc 9. A partition is installed at the other end of the vertical rod 10. An adjusting sleeve 11 is slidably connected to the outer side of the vertical rod 10. The outer wall of the movable disc 9 is located at... A side plate 12 is installed on one side of the upright 10. A limiting groove is opened inside the side plate 12. A limiting plate 13 is slidably connected inside the limiting groove. A first spring 14 is installed between one side of the limiting plate 13 and the inner wall of the limiting groove. A positioning plate is installed on the other side of the outer wall of the adjusting sleeve 11. A positioning post 15 is installed on one side of the positioning plate. Then, hold one end of the pull handle 26 and pull it to make the limiting plate 13 move inside the limiting groove and stretch the first spring 14, so that the positioning post 15 is pulled out from the positioning hole. At this time, the rubber post 17 is also taken away from the inner side of the binding groove and away from the surface of the movable post 5.

[0029] In this embodiment, as Figure 2 , Figure 3 and Figure 4 As shown, a pull handle 26 is installed on the other side of the outer wall of the positioning plate. Display plates 16 are installed on both sides of the outer wall of the fixed plate 8 on the movable plate 9. A positioning hole is opened on one side of the display plate 16, which is slidably connected to the positioning column 15. An extension rod is installed on the other end of the limiting plate 13. A binding groove extending to the surface of the movable column 5 is opened on one side of the outer wall of the movable sleeve 6. A rubber column 17 is installed on the other end of the extension rod. The rubber column 17 is slidably connected to the binding groove. Further, the pull handle 26 can be twisted to rotate the movable plate 9 on one side of the fixed plate 8, bringing the rubber column 17 away to the direction of the display plate 16 on the other side, so that the positioning column 15 is engaged with the positioning hole there. Then, the pull handle 26 can be held and pulled up and down to adjust the position of the auxiliary conveying component according to the height of the material. After the adjustment is completed, the positioning column 15 can be pulled out again, so that the rubber column 17 is re-aligned with the port of the binding groove and inserted. The first spring 14 returns to its original position and retracts, causing the rubber column 17 to be tightly pressed against the surface of the movable column 5 for positioning.

[0030] In this embodiment, as Figure 2 , Figure 3 and Figure 4As shown, the auxiliary conveying assembly includes a horizontal plate installed at the bottom of the movable sleeve 6. A positioning rod is installed at the bottom of the horizontal plate, and both ends of the positioning rod are rotatably connected to a first connecting plate 18. A second connecting plate is rotatably connected to the outer wall of the first connecting plate 18. Push plates 19 are installed at the other ends of two adjacent sets of second connecting plates and the other ends of two adjacent sets of first connecting plates 18. A synchronizing rod 20 is slidably connected to one end of the horizontal plate. A baffle is installed at one end of the synchronizing rod 20, and a protective frame 21 is installed at the other end of the synchronizing rod 20. Furthermore, the auxiliary roller 23 that contacts its surface during material conveying will also roll and deflect accordingly to ensure that the conveying is not affected. When the material is vibrated and bounces, the auxiliary roller 23 that contacts it can transmit the force to the protective frame 21, causing the first connecting plates 18 and the second connecting plates on both sides to deflect and retract accordingly. The push plate 19 slides inside the push groove, and the spring damping shock absorber 22 can retract accordingly to buffer and unload the transmitted force, continuously reducing the amplitude and force of the material's swaying, and at the same time reducing the possibility of surface damage caused by the material's collision.

[0031] The implementation principle of the automatic feeding structure of the hydraulic plate bending machine in this application embodiment is as follows: The material can be fed in through one end of the conveyor body 2 for conveying. At this time, the motor can be started according to the actual width of the material to be processed, driving the threaded rod 3 to rotate, so that the movable frame 24 and the slide rod 4 can move in opposite directions. After it is adjusted into place, when conveying, the guide roller 25 will contact the side surface of the material to limit it and prevent it from deviating. At the same time, the guide roller 25 can roll with the conveyor body 2 to convey the material without hindering the material conveying. Hold one end of the pull handle 26 and pull it to make the limiting plate 13 move inside the limiting groove and stretch the first spring 14, so that the positioning column 15 is pulled out from the positioning hole. At this time, the rubber column 17 is also taken away from the inner side of the binding groove and away from the surface of the movable column 5. Then, the pull handle 26 can be twisted to make the movable plate 9 rotate on one side of the fixed plate 8, taking the rubber column 17 away to the other side. With the orientation of the display plate 16 adjusted so that the positioning post 15 engages with the positioning hole, the pull handle 26 can be held up and down to adjust the position of the auxiliary conveying component according to the height of the material. After adjustment, the positioning post 15 can be pulled out again so that the rubber post 17 can be re-aligned with the port of the binding groove and inserted. The first spring 14 returns to its original position and retracts, causing the rubber post 17 to press tightly against the surface of the movable post 5 for positioning. During material conveying, the auxiliary roller 23 in contact with its surface will also roll and deflect to ensure that the conveying is not affected. When the material bounces and lifts due to vibration, the auxiliary roller 23 in contact with it can transmit the force to the protective frame 21, causing the first connecting plate 18 and the second connecting plate on both sides to deflect and retract. The push plate 19 slides inside the push groove, and the spring damping shock absorber 22 can retract accordingly to buffer and unload the transmitted force, continuously reducing the amplitude and force of the material's shaking, while reducing the possibility of surface damage caused by the material's collision.

[0032] The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
