Detailed Implementation

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] like Figure 1-2As shown, this utility model discloses an automatic loading and unloading bending device, comprising:

[0038] Machine 1;

[0039] A bending module includes a bending head 2 and a bending die 3 corresponding to the bending head 2, wherein the bending head 2 is connected to a drive assembly;

[0040] The shaping module includes a shaping head 4 and a shaping mold 5 corresponding to the shaping head 4. The shaping head 4 is connected to the driving component, and the shaping head 4 and the bending head 2 move up and down together.

[0041] The loading and unloading device includes a loading component 6 and a transferring component 7. The transferring component 7 includes a mounting plate 71. The bottom of the mounting plate 71 is provided with two sets of suction cups arranged side by side. The transferring component 7 drives the mounting plate 71 to move.

[0042] The advantages of adopting the above technical solution are that the overall structure is simple, the cost is low, it can realize the bending and shaping of the product, avoid cracking at the bending point, and ensure the bending quality.

[0043] In some implementations, the drive assembly includes a support rod 8, a support plate 81, a movable plate 82, and a drive component 83. The output end of the drive component 83 is connected to the movable plate 82. The bottom of the support rod 8 is fixed to the machine base 1, and the top is locked to the support plate 81. The movable plate 82 is provided with multiple bushings that move up and down along the support rod 8. There are four support rods, and their bottoms are locked to the machine base 1. The drive component 83 is a hydraulic cylinder, which is fixed to the mounting plate 71. Its extended end is connected to the movable plate 82, driving the movable plate 82 to move up and down.

[0044] The moving plate 82 is moved by the driving component 83, and the support rod 8 guides the moving plate 82 to ensure the correct bending position.

[0045] In some implementation schemes, such as Figure 4As shown, the bending head 2 is provided with a first pressing part and a bending part 23. A pressing block 21 is provided at the bottom of the first pressing part. The pressing block 21 is connected to the first pressing part by a spring 22. An installation rod is provided on the upper side of the bending head 2, and the installation rod is fixed to the installation plate 71. At the same time, a receiving cavity 26 is provided on the bending head 2. The spring 22 is located in the receiving cavity 26. A telescopic shaft 27 is also provided in the receiving cavity 26. The bottom of the receiving cavity 26 has a telescopic cavity for the telescopic shaft 27 to move. The spring 22 is sleeved on the telescopic shaft 27. The bottom of the telescopic shaft 27 is fixed to the pressing block 21, which serves as a connection. When the bending head 2 moves toward the product, the pressing block 21 is located on the lower side of the bending head 2 and first presses the product. Then it continues to descend, and the bending part 23 bends the product. At this time, the pressing block 21 retracts into the receiving cavity 26, which does not affect the bending effect. The pressing block 21 presses the product to ensure accurate bending position.

[0046] Furthermore, the bending part 23 is provided with an arc-shaped surface 24 and an inclined surface 25, and the bending die 3 is provided with a receiving surface 31 that cooperates with the arc-shaped surface 24 and the inclined surface 25. The arc-shaped surface 24 and the inclined surface 25 are symmetrically arranged to form a downward protrusion for bending the product. The receiving surface 31 of the bending die 3 cooperates with it to perform preliminary bending.

[0047] In some implementation schemes, such as Figure 5 As shown, the bottom surface of the shaping head 4 is provided with a protrusion 41, and the side of the protrusion 41 is provided with a shaping surface 42. The top and bottom surfaces of the shaping surface 42 have an arc transition. The protrusion 41 is used to shape the bent product. After the product undergoes preliminary bending and shaping, the processing is completed. No separate manual shaping step is required, which reduces product handling, ensures product quality, and ensures that the bending is in place.

[0048] Furthermore, the forming mold 5 is provided with a forming groove 51 that cooperates with the protrusion 41. Multiple limiting blocks 52 are provided around the forming groove 51. The limiting blocks 52 are fixed to the top of the forming mold 5 by locking. Multiple fixing holes are provided on the forming mold 5. By changing the fixing position of the limiting blocks 52, the limiting of products of different sizes can be achieved. At the same time, the same limiting blocks 52 can be set in the bending mold 3 for limiting.

[0049] In some implementation schemes, such as Figure 3 As shown, the suction cup assembly includes multiple suction cups 72. The upper side of each suction cup 72 is provided with a connection port, which is connected to an air pipe. The air pipe is connected to a vacuum generator. A lifting cylinder 73 is connected to the mounting plate 71. The lifting cylinder 73 drives the mounting plate 71 to rise and fall. A sensor is provided at the bottom of the mounting plate 71 to sense whether the product is placed in place. Photoelectric sensors or ultrasonic sensors are used.

[0050] The spacing between the suction cups is the same as the spacing between the bending mold 3 and the forming mold 5. A feeding box 12 is provided on the machine base 1. When the feeding and unloading positions are in place, the distance between the feeding box 12 and the forming mold 5 is the same as the distance between the bending mold 3 and the forming mold 5.

[0051] When unloading is required, the suction cup module simultaneously picks up the product located on the bending mold 3 and the shaping mold 5, moves it to the side by one position, transfers the bent product in the bending mold 3 to the shaping mold 5, and at the same time transfers the shaped product on the shaping mold 5 to the unloading box 12 for unloading. The transfer and unloading of the product are completed in one action, reducing the number of processing steps.

[0052] The feeding component 6 can also use a suction cup module to pick up the product to be processed and feed it onto the bending die 3.

[0053] Furthermore, the material transfer assembly 7 also includes a moving module 74, which drives the mounting plate 71 to move horizontally back and forth. The moving module 74 is fixed by a frame mounted on the machine base and includes a guide rail and a cylinder. The cylinder is horizontally set, and a connecting plate 75 is set on the guide rail. The connecting plate 75 moves along the guide rail. The cylinder is horizontally set, and its output end is connected to the mounting plate to drive the moving plate to move. It is supported by the frame on the machine base 1.

[0054] Furthermore, the machine tool 1 is also equipped with a transfer module 11. The transfer module 11 drives the bending die 3 and the forming die 5 to move between the loading and unloading device and the bending and forming modules. The transfer module 11 is equipped with a transfer plate 13. The bending die 3 and the forming die 5 are fixed on the transfer plate 13. The transfer module 11 adopts a lead screw motor module. The motor drives the lead screw to rotate, and the nut on the lead screw drives the transfer plate 13 to move. At the same time, a sensor is provided on the side of the transfer plate 13 to sense whether the transfer plate 13 is in position.

[0055] The working process is as follows: First, the transfer plate 13 is located at the loading position, and the loading component 6 picks up the product to be processed and places it onto the bending die 3. Second, the moving module 74 moves the transfer plate 13 to the lower side of the bending head 2, and the bending head 2 descends to perform bending. Third, the transfer plate 13 moves the product back to the loading position, the suction cup assembly descends, and transfers the product located on the bending die 3 to the forming die 5, while loading again. Fourth, the transfer plate 13 moves to the bending position, the bending head 2 descends to bend the newly placed product, and the forming punch descends simultaneously to shape the product. Fifth, the product returns to the loading position, at which point the two suction cup modules simultaneously pick up the product and move it to the side, moving the bent product to the forming die 5. At the same time, the product in the forming die 5 is moved to the unloading box 12 on the side for collection, and then loaded again. Steps four and five are repeated to complete the bending and shaping of the product. No manual operation is required, ensuring the bending quality of the product and improving processing efficiency.

[0056] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
