Description

Technical Field

[0001] This utility model belongs to the field of bending machine technology, specifically relating to an automatic feeding mechanism for a bending machine. Background Technology

[0002] In the field of sheet metal processing, bending machines, as an important processing equipment, are widely used in many industries such as construction, automotive, aerospace, and home appliances. They are used to bend sheet metal into various shapes to meet the design requirements of different products. With the continuous improvement of industrial automation and increasingly fierce market competition, higher demands are being placed on the efficiency, precision, and quality of bending processes. To meet these demands, the automation level of bending machines is constantly being improved. Among these, the automatic feeding mechanism, as a key component for achieving automated production in bending machines, directly affects the effect of the entire bending process. Insufficient feeding precision...

[0003] Currently, some automatic feeding mechanisms of bending machines on the market lack effective limiting and stabilizing mechanisms during the feeding process. For example, some feeding mechanisms rely solely on simple guide rails and push plates for feeding, which cannot accurately control the height and position of the material during movement. When the material size changes, the limiting structure cannot be adjusted in a timely and accurate manner, resulting in deviations when the material reaches the processing position of the bending machine, affecting the accuracy of bending processing, and thus reducing the quality of the product.

[0004] Therefore, this utility model provides an automatic feeding mechanism for a bending machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic feeding mechanism for a bending machine that can solve the problems mentioned in the background art.

[0006] The specific technical solution adopted in this utility model is as follows:

[0007] An automatic feeding mechanism for a bending machine includes a support platform, a movable feeding plate disposed on the support platform, an elastic element mounted on the top of the support platform for pulling the feeding plate upward, a limit plate disposed on the top of the support platform for limiting the height of the material, a movable moving seat disposed on the side of the support platform, a pusher plate disposed on the side of the moving seat for pushing the material, and a servo screw mounted on the surface of the support platform for moving the moving seat.

[0008] The present invention is further configured such that: the elastic element includes a slide rod installed on the top of the feeding plate, a connecting block is installed at the end of the slide rod, a support spring is installed at the bottom of the connecting block, and the support spring is connected to the top of the support platform.

[0009] The present invention is further configured such that: a support plate is installed on the top of the support platform, an adjustment frame is installed on the back of the limiting plate, a limiting seat is installed on the top of the adjustment frame, and the limiting seat is slidably connected to the support plate.

[0010] The present invention is further configured such that: a connector is installed on the surface of the limiting seat, and a plurality of insertion holes are arranged on the surface of the support plate, and the connector is used to be inserted into the insertion holes for limiting the support plate and the adjusting frame.

[0011] The present invention is further configured such that: the connector includes a connecting spring mounted on the surface of the limiting seat, a connecting plate is mounted on the end of the connecting spring, a plug rod is mounted on the side of the connecting plate, and the plug rod is inserted into the socket.

[0012] The present invention is further configured such that: a material discharge trough is provided on the top of the support platform, the material discharge trough is used to move materials between the support platform and the limiting plate, and a positioning plate is installed at the bottom of the limiting plate, the positioning plate being connected through the material discharge plate.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses an automatic feeding mechanism for a bending machine. A limiting plate is slidably connected to a support plate via an adjusting frame and a limiting seat, and is fixed in place by multiple insertion holes arranged on the surface of the support plate using connectors. This design allows operators to flexibly and precisely adjust the position of the limiting plate according to the dimensions of different materials. When the material moves under the push of the pusher plate, the limiting plate effectively restricts the height of the material, preventing height deviation during movement. Simultaneously, the positioning plate at the bottom of the limiting plate is connected to the feeding plate, further ensuring the stability of the feeding plate during movement and preventing uneven material placement due to unstable feeding plate movement, thus affecting feeding accuracy.

[0015] This utility model discloses an automatic feeding mechanism for a bending machine. The elastic component consists of a sliding rod mounted on top of the feeding plate, a connecting block at the end, and a support spring at the bottom of the connecting block. As material is consumed, the weight of the material on the feeding plate decreases. Under the action of elastic force, the support spring pulls the feeding plate upwards through the sliding rod and connecting block, ensuring that the material on the feeding plate remains in effective contact with the subsequent mechanism. This elastic design can accommodate materials of different weights, improving the equipment's adaptability to various materials. Furthermore, the connector, through the combination of a connecting spring, connecting plate, and insert rod, enables quick fixing and disassembly of the limit seat. When it is necessary to change to materials of different sizes for processing, the operator can quickly and conveniently adjust the position of the limit plate, greatly improving the equipment's flexibility and adaptability.

[0020] To make the purpose and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0021] like Figure 1-3 As shown, an automatic feeding mechanism for a bending machine includes a support platform 1, a movable feeding plate 2 on the support platform 1, the feeding plate 2 being movable via a slide rail or similar means, an elastic element 3 installed on the top of the support platform 1, the elastic element 3 exerting an upward pulling force on the feeding plate 2, specifically the elastic element 3 being connected to the feeding plate 2 via a connecting structure, and a limiting plate 4 installed on the top of the support platform 1, the limiting plate 4 being used to limit the height of the material to prevent the material from exceeding the specified height during movement. A movable seat 7 is provided on the side of the support platform 1. The movable seat 7 can be moved by means of a slide rail driven by a servo motor. A pusher plate 8 is installed on the side of the movable seat 7. The pusher plate 8 is used to push the material so that the material moves on the support platform 1. A servo screw 9 is installed on the surface of the support platform 1. The servo screw 9 is connected to the movable seat 7. The rotation of the servo screw 9 drives the movable seat 7 to move, thereby realizing the pusher plate 8 pushing the material. This automatic feeding mechanism pulls the feeding plate 2 through the elastic element 3 so that the material on the feeding plate 2 can move smoothly to the appropriate position. The limiting plate 4 limits the height of the material. The movable seat 7 drives the pusher plate 8 to push the material under the drive of the servo screw 9, realizing the automatic feeding of the material.

[0022] like Figure 1-3As shown, the elastic element 3 includes a slide rod 31 installed on the top of the feeding plate 2. The slide rod 31 can be fixed to the top of the feeding plate 2 by welding, bolt connection, or other methods. A connecting block 32 is installed at the end of the slide rod 31, and the connecting block 32 can be connected to the slide rod 31 by threaded connection or other methods. A support spring 33 is installed at the bottom of the connecting block 32. The upper end of the support spring 33 is connected to the connecting block 32, and the lower end is connected to the top of the support platform 1. The connection method can be a hook or other method. Through the combination of the slide rod 31, the connecting block 32, and the support spring 33, the elastic element 3 uses the elastic force of the support spring 33 to generate an upward pulling force on the feeding plate 2, so that the feeding plate 2 can move upward when the material decreases, ensuring effective contact between the material and the subsequent mechanism.

[0023] like Figure 2-3 As shown, a support plate 11 is installed on the top of the support platform 1. The support plate 11 can be fixed to the top of the support platform 1 by means of bolts or other methods. An adjustment frame 12 is installed on the back of the limiting plate 4. The adjustment frame 12 can be connected to the limiting plate 4 by means of welding or other methods. A limiting seat 14 is installed on the top of the adjustment frame 12. The limiting seat 14 is slidably connected to the support plate 11. The slidable connection can be achieved by setting a groove on the support plate 11 and setting a slider that cooperates with the groove on the limiting seat 14. The limiting plate 4 is slidably connected to the support plate 11 through the adjustment frame 12 and the limiting seat 14, so that the limiting plate 4 can move on the support plate 11. Thus, the position of the limiting plate 4 can be adjusted according to the size of the material to achieve the limiting of materials of different sizes.

[0024] As shown in Figure 2, a connector 15 is installed on the surface of the limiting seat 14. The connector 15 can be installed in a groove on the surface of the limiting seat 14. Multiple insertion holes 13 are arranged on the surface of the support plate 11, and the spacing of the insertion holes 13 can be set according to actual needs. The connector 15 is used to be inserted into the insertion holes 13. When the limiting seat 14 moves to a suitable position, the connector 15 is inserted into the insertion hole 13, which can limit the support plate 11 and the adjusting frame 12. By inserting the connector 15 into the insertion hole 13, the position of the limiting plate 4 can be quickly and accurately fixed, ensuring that the limiting plate 4 effectively limits the height of the material. At the same time, it is convenient to adjust the position of the limiting plate 4 according to different material sizes and then fix it.

[0025] like Figure 1-3As shown, the connector 15 includes a connecting spring 151 mounted on the surface of the limiting seat 14. The connecting spring 151 can be fixed in a groove on the surface of the limiting seat 14 by welding or other means. A connecting plate 152 is installed at the end of the connecting spring 151. The connecting plate 152 can be connected to the connecting spring 151 by bolts or other means. A plug rod 153 is installed on the side of the connecting plate 152. The plug rod 153 can be connected to the connecting plate 152 by welding or other means. When it is necessary to insert into the socket 13, press down the connecting plate 152 to retract the plug rod 153. After moving the limiting seat 14 to a suitable position, release the connecting plate 152. The plug rod 153 is inserted into the socket 13 under the action of the connecting spring 151. Through the combination of the connecting spring 151, the connecting plate 152 and the plug rod 153, the connector 15 realizes the quick fixing and disassembly of the limiting seat 14, which facilitates the adjustment and fixing of the position of the limiting plate 4.

[0026] like Figure 1 As shown, a material discharge trough 5 is provided on the top of the support platform 1. The material discharge trough 5 can be processed by milling or other methods. It is used to move materials between the support platform 1 and the limiting plate 4. A positioning plate 6 is installed at the bottom of the limiting plate 4. The positioning plate 6 can be connected to the limiting plate 4 by welding or other methods. The positioning plate 6 is connected to the feeding plate 2 through a through hole. The connection method is to set a through hole on the feeding plate 2, and the positioning plate 6 passes through the through hole to ensure the stability of the feeding plate 2 during the movement. The material discharge trough 5 provides a channel for the movement of materials, so that the materials can smoothly enter between the support platform 1 and the limiting plate 4. The positioning plate 6 ensures the stability of the feeding plate 2 during the movement and prevents the feeding plate 2 from shifting during the movement, which would affect the material feeding effect.

[0027] The working principle of this utility is as follows: The operator first conducts a comprehensive inspection of the automatic feeding mechanism of the bending machine, checking whether the support platform 1 is stable, whether the connection of each component is firm, whether the elasticity of the support spring 33 in the elastic component 3 is normal, whether the servo screw 9 runs smoothly, and whether the limit plate 4 and its adjustment structure are flexible, etc. The material to be processed is neatly placed on the feeding plate 2 to ensure that the material is placed stably and will not affect the subsequent feeding process due to improper placement.

[0028] Based on the actual dimensions of the material, determine the appropriate position to which the limiting plate 4 needs to be adjusted to ensure that the height of the material meets the requirements during movement and that the material is not damaged or the feeding is not smooth due to improper limiting. Push the limiting plate 4 to drive the adjusting frame 12 and the limiting seat 14 to slide in the groove on the support plate 11. Move the limiting seat 14 to the vicinity of the insertion hole 13 corresponding to the material size. Press down the connecting plate 152 in the plug-in 15 to retract the insertion rod 153. After moving the limiting seat 14 to the accurate position, release the connecting plate 152. The insertion rod 153 pops out under the action of the connecting spring 151 and inserts into the corresponding insertion hole 13, thus completing the fixing of the position of the limiting plate 4.

[0029] Before the pusher plate 8 pushes the material, the material moves through the material discharge groove 5 at the top of the support platform 1 to between the support platform 1 and the limiting plate 4. At the same time, the positioning plate 6 at the bottom of the limiting plate 4 passes through the through hole on the feeding plate 2 to ensure the stability of the feeding plate 2 during subsequent movement. As the material is consumed, the weight of the material on the feeding plate 2 is reduced. Under the elastic force of the support spring 33 in the elastic element 3, the feeding plate 2 is pulled upward through the slide rod 31 and the connecting block 32, so that the material on the feeding plate 2 always maintains effective contact with the subsequent mechanism.

[0030] Furthermore, the servo screw 9 is activated, causing the moving seat 7 to move on the slide rail on the side of the support platform 1. The pusher plate 8 on the side of the moving seat 7 moves accordingly, pushing the material forward on the support platform 1. When the pusher plate 8 pushes the material to the processing position of the bending machine, the servo screw 9 stops rotating, and the moving seat 7 and pusher plate 8 stop moving. The material accurately reaches the designated position, waiting for the bending machine to process it. The operator checks whether the material is in place accurately. If there is no error, the next material placement and feeding preparation can be carried out. If there is a deviation, the equipment or material position should be adjusted in time to ensure the smooth progress of subsequent feeding and processing.

[0031] In addition, the automatic feeding mechanism of the bending machine should be cleaned regularly to remove dust, debris, and processing residue from components such as the support table 1, feeding plate 2, and limit plate 4. This will prevent the accumulation of debris from affecting the operation of the equipment. The moving parts such as the servo screw 9 and slide rail should be lubricated and maintained by adding an appropriate amount of lubricating oil to reduce wear and ensure the smooth and stable operation of the equipment. The wear of each component should be checked regularly. If the elasticity of the support spring 33 in the elastic component 3 is weakened or the connecting spring 151 in the plug-in component 15 is damaged, it should be replaced in time to ensure the normal operation of the equipment.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
