The storage box and the base are respectively fixed on the support, and the feeding trough is fixed on the base. The end of the feeding trough away from the storage box is in close contact with the bending machine. The bottom of the storage box has the pushing trough, and the upper part of the pushing block is slidably connected in the pushing trough. The piston rod of the first cylinder passes through the fixing plate and is fixedly connected to the pushing block. This utility model can realize automatic feeding of metal sheets for bending machines, with strong automation and no need for manual feeding. It also has strong stability and high conveying efficiency, further improving the working efficiency of bending machines." However, it still has the following drawbacks: The current device is ineffective at handling and guiding sheet metal parts of varying sizes. When faced with sheet metal parts of significantly different dimensions, it cannot automatically adjust to accommodate edges or contours of varying sizes, leading to misalignment, jamming, or even damage during transport. This not only increases the equipment failure rate and reduces production continuity but may also cause irreversible damage to the sheet metal parts themselves, affecting the product's appearance and performance. Therefore, a sheet metal part feeding device for an automatic bending machine is proposed. Utility Model Content

[0004] The purpose of this invention is to address the current limitations in handling and guiding sheet metal parts of different sizes. When faced with sheet metal parts of varying dimensions, the device cannot automatically adjust to accommodate edges or contours of different sizes, leading to misalignment, jamming, or even damage during transport. This not only increases equipment failure rates and reduces production continuity but may also cause irreversible damage to the sheet metal parts themselves, affecting the product's appearance and performance. The invention provides a sheet metal part feeding device for an automatic bending machine to solve the problems mentioned in the background.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The present invention is as follows: a sheet metal feeding device for an automatic bending machine, including a base, wherein the base is provided with a feeding component for feeding sheet metal parts of different sizes, and the base is provided with an auxiliary component for feeding sheet metal parts.

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0017] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0018] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0019] like Figure 1 and Figure 2 As shown, this embodiment proposes a sheet metal parts feeding device for an automatic bending machine, including a base 1, a feeding component 2 for feeding sheet metal parts of different sizes is provided inside the base 1, and an auxiliary component 3 for assisting in feeding sheet metal parts is provided inside the base 1. like Figure 2 and Figure 3As shown, the feeding assembly 2 includes a hydraulic rod 201 disposed on the inner top wall of the base 1. A bending punch 202 is disposed at the output end of the hydraulic rod 201, and a bending die 203 is disposed on the inner bottom wall of the base 1. The hydraulic rod 201 pushes the bending punch 202 downwards, engaging with the bending die 203 to bend the sheet metal part. First electric push rods 204 are disposed on opposite sides of the base 1, and push plates 205 are disposed at the output ends of both first electric push rods 204. The first electric push rods 204 push the push plates 205 closer to the sheet metal part, thus tidying up the sheet metal part on the conveyor belt 206. A conveyor belt 206 is disposed on the inner wall of the base 1. A high-definition camera 207 is installed on the inner top wall of the base 1. The high-definition camera 207 is a MER-500-14GM model from Daheng Imaging. A controller 208 is installed on the top of the base 1. The controller 208 is a Siemens S7-1200 model. The high-definition camera 207 monitors the position of the sheet metal parts on the conveyor belt 206 in real time. A collection frame 209 is fixedly connected to one side of the base 1. A drawer 210 is slidably connected to the inner wall of the collection frame 209. The bent sheet metal parts are collected through the drawer 210 inside the collection frame 209. The conveyor belt 206 and the high-definition camera 207 are both electrically connected to the controller 208. Connect the conveyor belt 206 to an external power source and start it, thereby moving the sheet metal parts on the conveyor belt 206. Activate the first electric push rod 204, which pushes the push plate 205 closer to the sheet metal parts according to their length. This organizes and guides the sheet metal parts on the conveyor belt 206, ensuring they enter the bending area in an orderly manner and avoiding a chaotic situation. When the high-definition camera 207 detects that the sheet metal parts have been accurately pushed onto the bending die 203, it transmits a signal to the controller 208. The controller 208... Upon receiving the signal, 8 issues a command to stop the operation of the conveyor belt 206, activates the hydraulic rod 201 to drive the bending punch 202 to descend, and cooperates with the bending die 203 to complete the bending and forming of the sheet metal. After the bending action is completed, the bending punch 202 returns to its original position and rises. At this time, the conveyor belt 206 continues to transport new sheet metal into the bending area. During the transport process, the new sheet metal comes into contact with the already bent sheet metal, and with the push force of the conveyor belt 206, the bent sheet metal is pushed into the drawer 210 of the collection frame 209, which greatly improves the conveying and feeding efficiency of sheet metal parts.

[0020] like Figure 4As shown, the auxiliary component 3 includes a second electric push rod 301 disposed on the inner top wall of the base 1, and a pressure plate 302 is disposed at the output end of the second electric push rod 301. When the conveyor belt 206 stops conveying the sheet metal parts, the controller 208 synchronously starts the second electric push rod 301, which pushes the pressure plate 302 down to fix the sheet metal parts on the conveyor belt 206. This prevents the vibration force generated when bending the sheet metal parts from causing misalignment of the sheet metal parts on the conveyor belt 206, thereby ensuring the accuracy of bending.

[0021] like Figure 3 As shown, two support columns 4 are fixedly connected to each of the opposite sides of the base 1, and all four support columns 4 are slidably connected to one side of the push plate 205. The support columns 4 provide guidance for the movement of the push plate 205, enabling the push plate 205 to move accurately along a straight line and ensuring the positioning accuracy of the sheet metal parts.

[0022] like Figure 4 As shown, multiple springs 5 ​​are fixedly connected to the inner bottom wall of drawer 210, and a support plate 6 is fixedly connected to the end of each spring 5 away from drawer 210. When the bent sheet metal part is placed into drawer 210, the springs 5 ​​on the inner bottom wall of drawer 210 are compressed under pressure. The support plate 6 acts as a buffer for the sheet metal part under the action of the springs 5, reducing the collision force between the sheet metal part and the inner wall of drawer 210, and protecting the bent sheet metal part from damage.

[0023] like Figure 5 As shown, two connecting columns 7 are slidably connected to the inner wall of the base 1. A stabilizing plate 8 is fixedly connected to one end of each connecting column 7. Limiting rings 9 are provided on the outer walls of both connecting columns 7. When it is necessary to bend the sheet metal part, the connecting column 7 can be pushed to bring the stabilizing plate 8 close to the sheet metal part and fix the sheet metal. The movement range of the connecting column 7 is limited by the limiting rings 9 to prevent the stabilizing plate 8 from moving excessively.

[0024] like Figure 4 As shown, the bottom of the pressure plate 302 is provided with an anti-slip pad 10, and the bottom of the anti-slip pad 10 has multiple anti-slip grooves 11. When the pressure plate 302 presses down on the sheet metal part, the anti-slip pad 10 contacts the surface of the sheet metal part, and the anti-slip grooves 11 increase the friction between the anti-slip pad 10 and the sheet metal part, preventing the sheet metal part from sliding under pressure. This effectively improves the friction between the pressure plate 302 and the sheet metal part, enhances the fixing effect of the pressure plate 302 on the sheet metal part, and further ensures the stability of the sheet metal part during the feeding process.

[0025] like Figure 5As shown, the outer wall of the conveyor belt 206 is provided with multiple protective pads 12, which are evenly distributed along the length of the conveyor belt 206. When sheet metal parts are conveyed on the conveyor belt 206, the protective pads 12 play a buffering and protective role, effectively protecting the surface quality of the sheet metal parts during the conveying process and reducing scratches, deformation and other problems caused by friction and collision.

[0026] Specifically, when using the sheet metal feeding device of this automatic bending machine: the conveyor belt 206 is connected to an external power source and started, thereby moving the sheet metal parts on the conveyor belt 206. The first electric push rod 204 is activated, and the first electric push rod 204 pushes the push plate 205 closer to the sheet metal part according to the length of the sheet metal part, which plays a role in organizing and guiding the sheet metal parts on the conveyor belt 206, ensuring that the sheet metal parts can enter the bending area in an orderly manner and avoiding a chaotic situation. When the high-definition camera 207 detects that the sheet metal part has been accurately pushed into the bending die 203, it transmits a signal to the control unit. After receiving a signal, the controller 208 issues a command to stop the conveyor belt 206 and activates the hydraulic rod 201 to lower the bending punch 202, which works in conjunction with the bending die 203 to complete the bending of the sheet metal. After the bending action is completed, the bending punch 202 returns to its original position and rises. At this time, the conveyor belt 206 continues to transport new sheet metal into the bending area. During the transport process, the new sheet metal comes into contact with the already bent sheet metal, and with the pushing force of the conveyor belt 206, the bent sheet metal is pushed into the drawer 210 of the collection frame 209, which greatly improves the conveying and loading efficiency of sheet metal parts (e.g., ...). Figure 2 and Figure 3 (As shown); when the conveyor belt 206 stops conveying the sheet metal parts, the controller 208 simultaneously activates the second electric push rod 301. The second electric push rod 301 pushes the pressure plate 302 down, fixing the sheet metal parts on the conveyor belt 206. This prevents the vibration force generated when bending the sheet metal parts from causing misalignment of the sheet metal parts on the conveyor belt 206 (e.g., Figure 4 (as shown in the image); thus ensuring the accuracy of the bending.

[0027] All technical features in this embodiment can be freely combined according to actual needs.

[0028] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
