[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Example 1

[0029] Please refer to the appendix. Figure 1-7 A high-precision intelligent bending machine includes a bending machine body 1, wherein the bending machine body 1 is equipped with an upper mold 2 driven by hydraulic pressure and a fixed lower mold 31. The machine is characterized by further including a transfer table 3, a workpiece transfer mechanism 4, a back gauge mechanism 5, a back gauge combination adjustment mechanism 6, and a back gauge plate driving mechanism 7, wherein:

[0030] The transmission table 3 is fixed to the front end of the bending machine body 1, and the lower mold 31 is fixed to the upper end of the transmission table 3 and corresponds to the upper mold 2;

[0031] The workpiece transfer mechanism 4 includes a push plate 41 that is installed on the upper end of the transfer table 3 and is driven by a cylinder to push the workpiece to the lower mold 31.

[0032] The back gauge mechanism 5 includes multiple independently movable combined baffles 52, which are used to block and limit the workpiece;

[0033] The rear baffle plate driving mechanism 7 includes a transmission table 74 that can move back and forth by being driven by a motor. The transmission table 74 is located at the rear end of the baffle 52 and is used to push the baffle 52 to move.

[0034] The baffle assembly adjustment mechanism 6 includes multiple connecting cylinders 63 installed at the bottom of the baffle 52, and the output end of the connecting cylinder 63 is equipped with a connecting plate 631 for connecting the transmission table 74 and the baffle 52.

[0035] Please refer to the appendix. Figure 5 , Figure 6 , Figure 7 The rear gutter mechanism 5 also includes a top plate 51 installed on the upper end of the baffle 52. The bottom of the top plate 51 is provided with a plurality of guide grooves 511 corresponding to the baffle 52, and the top of the baffle 52 is provided with a guide seat 521 that is slidably connected to the guide grooves 511.

[0036] In this embodiment, since the baffles 52 are in close contact with each other, the guide groove 511 can limit the baffles 52 so that the baffles 52 will not deviate or get stuck with the adjacent baffles 52 during the movement.

[0037] Please refer to the appendix. Figure 6 The rear baffle drive mechanism 7 also includes mounting brackets 71 symmetrically installed in the machine body. A drive motor 73 is installed at the rear end of the mounting bracket 71. A screw 72 is rotatably connected between the mounting brackets 71 at the output end of the drive motor 73. A sliding table 75 with a screw hole is sleeved on the outer wall of the screw 72. The sliding table 75 is threadedly connected to the screw 72 through the screw hole. The transmission table 74 is installed between the sliding tables 75.

[0038] Furthermore, the connecting plate 631 is symmetrically equipped with connecting blocks 632 on both sides near the baffle 52 and the transmission table 74. The bottom of the baffle 52 and the transmission table 74 are provided with slots 522. The connecting blocks 632 and the slots 522 are movably connected and fit together. Both the connecting blocks 632 and the slots 522 are T-shaped.

[0039] In this embodiment, the drive motor 73 drives the screw 72 to rotate, and the sliding table 75, which is threadedly connected to the screw 72, drives the transmission table 3 to move forward. The forward movement of the transmission table 3 drives the part of the baffle 52 connected to the transmission table to move forward. At this time, part of the baffle 52 moves forward, while the other part of the baffle 52 remains unchanged. The movable baffle 52 has a concave-convex structure to adapt to the corresponding workpiece.

[0040] Please refer to the appendix. Figure 7 The material blocking combination adjustment mechanism 6 also includes a mounting plate 61 installed at the bottom of the connecting cylinder 63. The upper end of the mounting plate 61 is provided with a plurality of sliding grooves 62, and the bottom of the connecting cylinder 63 is provided with a sliding seat 633 that is slidably connected to the sliding grooves 62.

[0041] In this embodiment, when the transmission table 3 moves the baffle 52 via the connecting plate 631 through the sliding seat 633 and the sliding groove 62, the connecting cylinder 63 can also move smoothly accordingly. Example 2

[0042] Based on the above embodiment one, please refer to the appendix. Figure 2 , Figure 3 The workpiece transfer mechanism 4 also includes a transfer table 42 installed on the transfer table 3. A conveying cylinder 43 is symmetrically installed at the bottom of the transfer table 42. A connecting frame 431 fixedly connected to the push plate 41 is installed at the output end of the conveying cylinder 43.

[0043] Furthermore, the upper end face of the transfer table 42 is symmetrically provided with a through movable groove 421, and the connecting frame 431 passes through the movable groove 421 and is movably connected to the movable groove 421.

[0044] In this embodiment, the conveying cylinder 43 drives the push plate 41 to move, and the push plate 41 drives the workpiece to move above the lower mold 31. As the workpiece moves forward, the front end of the workpiece contacts the baffle 52 and abuts against the baffle 52 for positioning. No manual feeding is required, which improves the accuracy of feeding and positioning.

[0045] The working principle and usage process of this utility model are as follows: Before processing, the baffle 52 is adjusted according to the shape of the workpiece to be processed. The CNC system starts the matching position of the partial connecting cylinder 63. The partial connecting cylinder 63 drives the connecting plate 631 to move upward. The connecting plate 631 drives the connecting block 632 to move upward. The connecting block 632 moves upward and inserts into the slot 522 at the bottom of the transfer table 3 and the baffle 52. At this time, part of the baffle 52 is connected to the transfer table 3 through the connecting plate 631 and the connecting block 632. At this time, the drive motor 73 is started. The drive motor 73 drives the screw 72 to rotate. The sliding table 75, which is threadedly connected to the screw 72, drives the transfer table 3 to move forward. The forward movement of the transfer table 3 drives part of the baffle 52 connected to the transfer table to move forward. At this time, part of the baffle 52 moves forward, while the other part of the baffle 52 remains unchanged. The movable baffle 52 has a concave-convex structure, which is used to position complex workpieces.

[0046] During processing, the complex-shaped workpiece (hereinafter referred to as the workpiece) is neatly placed in front of the push plate 41 and the orientation of the workpiece is adjusted. Then, the conveying cylinder 43 is started, and the conveying cylinder 43 drives the push plate 41 to move. The push plate 41 drives the workpiece to move above the lower mold 31. As the workpiece moves forward, the front end of the workpiece contacts the concave-convex combination baffle 52 and abuts against the baffle 52 for positioning. At this time, the upper mold 2 can be started for bending.
