Description

Technical Field

[0001] This utility model relates to the field of automatic bending technology, specifically an automatic repositioning bending machine. Background Technology

[0002] A CNC bending machine is a sheet metal forming machine designed for cold-rolled sheet metal processing, using equipped molds to bend cold-state metal sheets into workpieces of various geometric cross-sectional shapes. In practical applications, some sheets require multiple bends. To automate the bending process, existing technologies typically place a horizontal positioning fixture near the bending machine body to hold the sheet metal. A robotic arm grips the sheet metal, places it on the fixture, positions it, and then re-grips it and places it back into the bending machine body for bending. However, this design suffers from a large robotic arm stroke, resulting in low positioning efficiency and a slow automatic bending cycle. Furthermore, this layout requires a large footprint, placing limitations on the customer's available space. Summary of the Invention

[0003] To overcome the shortcomings of existing technologies, this utility model provides an automatic repositioning bending machine. This machine features a first support frame and a second support frame on its main body for placing sheet metal. During automatic bending, a robotic arm clamps the sheet metal after its first bend and places it on the first and second support frames. The robotic arm adjusts its clamping angle to reposition the sheet metal and then places it on the machine body for subsequent bending. The second support frame can move along the length of the bending machine's pressure plate under the drive of a driving device, thereby adjusting the distance between the first and second support frames to accommodate sheet metal of different sizes. This design reduces the number of robotic arms required, speeds up the automatic bending cycle, and significantly reduces the required floor space.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: an automatic shifting bending machine, comprising a bending machine body, the bending machine body having a lower worktable, and a shifting fixture connected to the bending machine body, the shifting fixture comprising:

[0005] The first support frame is mounted on the lower worktable of the bending machine body;

[0006] The second support frame is slidably connected to the lower worktable of the bending machine body;

[0007] A driving device is disposed between the bending machine body and the second support frame. Under the action of the driving device, the second support frame can slide back and forth along the length direction of the bending machine's pressure plate.

[0008] The driving device includes a motor connected to the second support frame. The motor has a gear on its rotating shaft and a toothed edge arranged along the length of the bending machine's pressure plate on its body. The motor drives the gear to roll along the toothed edge, thereby driving the second support frame to move.

[0009] Through the above technical solution, the automatic repositioning bending machine is equipped with a first support frame and a second support frame for placing sheet metal on the bending machine body. During the automatic bending process, a robotic arm clamps the sheet metal after the first bend and places it on the first and second support frames. The robotic arm adjusts the clamping angle to complete the repositioning and then clamps the sheet metal onto the bending machine body to complete subsequent bends. The second support frame can move along the length of the bending machine's pressure plate under the drive of a driving device, thereby adjusting the distance between the first and second support frames to accommodate sheet metal of different sizes. This solution reduces the number of robotic arms required, speeds up the automatic bending cycle, and significantly reduces the required floor space.

[0010] Furthermore, the lower worktable of the bending machine body is provided with a slide rail, which extends along the length direction of the pressure plate of the bending machine;

[0011] The first support frame and the second support frame each include:

[0012] Support plate, which is connected to the lower worktable of the bending machine body;

[0013] A support plate is provided, which is connected to the support plate, and the support plate and the support plate are respectively provided with connecting holes;

[0014] A fastener passes through the connecting hole to securely connect the support plate to the base plate;

[0015] The second support frame has a support plate equipped with a slider, which is slidably connected to the slide rail.

[0016] The above technical solution allows for adjustment of the height of the support plate according to the size of the sheet material to be bent, thereby improving the repositioning efficiency.

[0017] The driving device drives the support plate to reciprocate along the slide rail, thereby adjusting the distance between the second support frame and the first support frame. The slide rail is horizontally positioned to ensure that the second support frame and the first support frame are flush.

[0018] Furthermore, the support plate and / or the bracing plate are provided with at least two connecting holes arranged in the vertical direction;

[0019] The fastener includes a quick-release rod, the nut end of which passes through the connecting hole of the support plate and is fixedly connected to the connecting hole of the support plate. By locking the handle of the quick-release rod, the support plate and the support plate can be fixed.

[0020] The height of the support plate can be adjusted by adjusting the position of the connecting hole through which the quick-release rod passes.

[0021] Optionally, the support plate and / or the base plate may have only one vertically extending connecting hole. When the height of the base plate needs to be adjusted, turn the handle to release the locking state, adjust the base plate to the preset height, and then turn the handle to lock the base plate and the base plate. This solution makes the height adjustment of the base plate very simple and convenient.

[0022] Furthermore, the support plate is provided with rollers on the side facing the bending machine body, and the rollers abut against the bending machine body. When the drive device moves the support plate, the rollers roll along the surface of the bending machine body, which can prevent the support plate from scratching the bending machine body.

[0023] Furthermore, electromagnetic chucks are provided on the support plates of the first and second support frames, and at least one electromagnetic chuck is provided on the upper side of each support plate. In order to ensure that the plate moves when the robotic arm adjusts the clamping angle, this application provides an electromagnetic chuck to attract the plate. After the robotic arm clamps the plate again, the electromagnetic chuck releases the plate.

[0024] Furthermore, the first support frame and the second support frame are each provided with a connecting plate, and the connecting plate is provided with the slider, which is slidably connected to the slide rail. That is, the initial position of the first support frame is adjustable.

[0025] Furthermore, the connecting plate is provided with a threaded hole, and a positioning screw passes through the threaded hole. The positioning screw can be rotated to abut against the slide rail. By tightening the screw to abut against the slide rail, the position of the first support frame or the second support frame relative to the bending machine can be fixed.

[0026] Furthermore, the driving device includes a motor, which is located on the side of the support plate of the second support frame relative to the first support frame. The motor has a gear on its rotating shaft, and the bending machine body has teeth arranged along the length direction of the bending machine's pressure plate. The motor drives the gear to roll along the teeth, thereby driving the second support frame to move.

[0027] A tray is provided on the bending machine body and below the second support frame. A cable chain is provided on the tray for storing the wiring harness connected to the motor.

[0028] Based on the above technical solution, the beneficial effects of this utility model are as follows:

[0029] The automatic repositioning bending machine disclosed in this application has a first support frame and a second support frame on the bending machine body for placing sheet metal. During the automatic bending process, a robotic arm clamps the sheet metal after the first bend and places it on the first and second support frames. The robotic arm adjusts the clamping angle to complete the repositioning and then clamps the sheet metal onto the bending machine body to complete subsequent bending. The second support frame can move along the length of the bending machine's pressure plate under the drive of a drive device, thereby adjusting the distance between the first and second support frames to accommodate sheet metal of different sizes. This solution reduces the number of robotic arms, speeds up the automatic bending cycle, and significantly reduces the required floor space.

[0030] In this application, the support plate is provided with a connecting hole extending in the vertical direction. The support plate is fixed in the connecting hole by a quick release rod. The height of the support plate can be adjusted by turning the handle to release the locking state.

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.

[0038] It should be noted that in the description of this utility model, the terms "first," "second," etc., are used only for descriptive purposes and to distinguish similar objects; there is no order between them, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0039] Example: Combining Figure 1-3 As shown, this embodiment discloses an automatic shifting bending machine, including a bending machine body 1, on which a shifting fixture is connected. The shifting fixture includes:

[0040] A first support frame 2 includes a first support plate 21. The first support plate 21 has a first connecting hole 211 extending vertically. A first quick-release rod 22 passes through the first connecting hole 211. The nut end of the first quick-release rod 22 passes through the first connecting hole 211 and connects to a first support plate 23. By locking the handle of the quick-release rod 22, the first support plate 23 and the first support plate 21 can be fixed. When the height of the first support plate 23 needs to be adjusted, simply rotate the handle of the first quick-release rod 22 to release the lock, adjust the first support plate 23 to the preset height, and then rotate the handle to lock the first support plate 23 and the first support plate 21 back into place. This design makes the height adjustment of the first support plate 23 very simple and convenient.

[0041] In another feasible embodiment, the first support plate 21 and the first support plate 23 are provided with a plurality of connecting holes arranged in a vertical direction. By passing bolts through the connecting holes of the first support plate 21 and the first support plate 23 and tightening them, the first support plate 21 and the first support plate 23 can be fixedly connected. The height of the first support plate 23 can be adjusted by adjusting the position of the connecting holes through which the bolts pass.

[0042] A connecting plate 3 is also provided on the first support plate 21, and a slider 32 is provided on the connecting plate 3. The lower worktable of the bending machine body 1 is provided with a slide rail 33 extending along the length direction of the bending machine's pressure plate, and the slider 32 is slidably connected to the slide rail 33.

A roller 4 is connected to the side of the first support plate 21 facing the bending machine body 1, and the roller 4 abuts against the outer shell of the bending machine body 1. When the first support frame 2 slides along the slide rail 33, the roller 4 rolls along the outer shell of the bending machine body 1, thereby preventing the first support plate 21 from scratching the bending machine body 1.

[0043] The connecting plate 3 is also provided with a threaded hole, and a positioning screw 31 is provided in the threaded hole. The positioning screw 31 can be rotated to abut against the slide rail 33.

[0044] The transposition fixture also includes a second support frame 5, which includes a second support plate 51. The second support plate 51 has a second connecting hole 511 extending vertically. A second quick-release rod 52 passes through the second connecting hole 511. The nut end of the second quick-release rod 52 passes through the first and second connecting holes 511 and connects to a second support plate 53. By locking the handle of the quick-release rod 52, the second support plate 53 and the second support plate 51 can be fixed. When the height of the second support plate 53 needs to be adjusted, simply rotate the handle of the second quick-release rod 52 to release the locking state, adjust the second support plate 53 to the preset height, and then rotate the handle to lock the second support plate 53 and the second support plate 51 back into place.

[0045] The above technical solution allows for adjustment of the height of the first support plate 23 and the second support plate 53 as needed, facilitating the robotic arm's gripping of the plates and improving the repositioning efficiency.

The bending machine body has toothed grooves arranged along the length of the bending machine's pressure plate. The motor 6 drives the gear to roll along the toothed grooves, thereby driving the second support frame 5 to slide back and forth along the slide rail 33 to adjust the distance between the second support frame 5 and the first support frame 2. This design allows the support fixture to adapt to different sizes of sheet metal to be bent. The motor is connected to a PLC controller in the automatic bending unit. The PLC controller drives the motor in real time according to the size of the sheet metal to be bent, moving the second support frame 5 to adjust the distance between the second support frame 5 and the first support frame 2.

[0048] In another feasible embodiment, an electric cylinder is provided on the bending machine body 1. The drive end of the electric cylinder is connected to the second support plate 53. The electric cylinder is connected to a PLC controller. The PLC controller drives the electric cylinder to push the second support frame 5 in real time according to the size of the sheet material to be bent, so as to adjust the distance between the second support frame 5 and the first support frame 2.

[0049] The transposition fixture also includes a cable chain 61. A support plate 62 is fixedly connected to the bending machine body 1 and located below the second support frame 5, and the cable chain 61 is disposed on the support plate 62. The cable chain 61 is used to store the wiring harness connected to the motor 6.

[0050] In one feasible embodiment, the bending machine body 1 of the automatic bending machine is provided with a first support frame 2 and a second support frame 5.

[0051] Electromagnetic chucks 7 are respectively provided on the first support plate 23 and the second support plate 53. In a feasible embodiment, two electromagnetic chucks 7 are respectively provided on the first support plate 23 and the second support plate 53. The electromagnetic chucks 7 are used to adsorb the sheet material to be bent.

[0052] When using the aforementioned automatic repositioning bending machine to bend sheet metal, the automatic repositioning bending machine is arranged in an automatic bending unit. After the sheet metal is bent for the first time, the robotic arm in the automatic bending unit grips the sheet metal and places it on the first support plate 23 and the second support plate 53. The electromagnetic chuck 7 attracts and fixes the sheet metal. The robotic arm adjusts the position of the gripping sheet metal to achieve the purpose of repositioning. After the robotic arm grips the sheet metal again, the electromagnetic chuck 7 releases the sheet metal, and the robotic arm places the sheet metal into the bending machine body for bending.
