According to the size of the opening and closing angles of the hinge mold groove 9, the feed depth of the bending machine during the bending operation can be further adjusted to meet different processing requirements.

[0028] Among them, both ends of the base 1 are rotatably connected with screw rods 16, one end of the two screw rods 16 passes through the bottom of the connecting frame 15 and is rotatably connected to the connecting frame 15, the connecting frame 15 is fixedly connected to the worktable 2, the screw rod 16 passes through the lifting limit block 17 and is threadedly connected to the lifting limit block 17, the lifting limit block 17 is slidably connected to the inner wall of the connecting frame 15, and the lifting limit block 17 can perform precise lifting and lowering movements in the inner wall of the connecting frame 15 as the screw rod 16 rotates, thereby ensuring that it can be lifted and lowered in coordination with the opening and closing of the hinge die groove. This design not only improves the accuracy of the bending process, but also further ensures the feed depth of the die knife during the processing.

[0029] Among them; a slide groove 19 is provided on the top of the loading platform 2, and the slide groove 19 is slidably connected to a moving frame 20, and an annular groove is provided at the bottom of the moving frame 20, and a connecting rod is slidably connected to the annular groove, and one end of the connecting rod is fixedly connected to a worm gear 25, and the worm gear 25 is meshed with a worm 24, and one end of the worm 24 is provided with a rotating handle, and the worm gear 25 is coaxially threadedly connected to a threaded rod 23, and one end of the threaded rod 23 passes through the moving frame 20, and one end of the threaded rod 23 is rotatably connected to a top plate 22. Since the position of the top plate 22 can be precisely adjusted, it can ensure that the metal sheet always remains in the correct position during the bending process, matching the opening and closing angles of the hinge die groove. This precise alignment reduces processing errors and improves the accuracy and consistency of the bending process.

This design makes the power transmission direction more flexible and changeable. At the same time, the meshing of the bevel gears ensures the accuracy and stability of the transmission. The coaxial fixed connection between the bevel gear 2 13 and the worm 14 further transmits power to the worm gear mechanism, thereby realizing precise control of subsequent components.

[0034] Among them; a method for using a bending machine feed depth adjustment mechanism, characterized in that the method is applied to a bending machine feed depth adjustment mechanism as claimed in any one of claims 1 to 7 above, and the method comprises the following steps:

[0035] Step 1: According to the bending requirements of the required metal sheet, the spur gear 4 at one end of the rotating shaft 3 is driven to rotate by the rotating motor 10, so as to drive the two connecting rods 6 on the top of the stage 2 and the push blocks 7 installed at both ends of the connecting rods 6 to move toward the center of the stage 2, so as to control the moving distance to adjust the opening and closing degree of the hinge die groove 9. The smaller the opening and closing angle of the hinge die groove 9, the deeper the feed depth, and vice versa. The hinge die groove 9 is adjusted to a suitable opening and closing angle. At the same time, the lifting limit block 17 will also lift and lower with the opening of the hinge die groove 9, so as to play an auxiliary limiting role for the punching die in the bending machine;

[0036] Step 2: Move the two movable frames 20 slidably connected in the slide groove 19 to a suitable position, and then realize the lifting and lowering of the threaded rod 23 by rotating the handle at one end of the worm gear 24, so as to adjust the top plate 22 rotatably connected at one end of the threaded rod 23 to a height adapted to the hinge mold groove 9;

[0037] Step 3: Place the metal sheet to be bent on the top of the top plate 22, and push the end of the sheet to be bent to the top of the hinge die groove 9, and then cooperate with the die knife of the bending machine to perform the bending operation.

[0038] Working principle: when in use, first start the rotating motor 10 at the bottom of the stage 2, and its output shaft starts to rotate. This rotational action is transmitted to the rotating shaft 3 through a direct connection, so that the rotating shaft 3 rotates accordingly. A spur gear 4 is coaxially fixed to one end of the rotating shaft 3. Therefore, as the rotating shaft 3 rotates, the spur gear 4 will also rotate synchronously. The spur gear 4 is meshed with two racks 5. When the spur gear 4 rotates, it will drive the two racks 5 to move relative to each other. This relative movement is carried out along the length direction of the racks 5, that is, the two racks 5 will move toward each other or away from each other. The ends of the racks 5 are each fixedly mounted with a connecting rod 6. Therefore, as the racks 5 move, the connecting rod 6 will also move accordingly. At both ends of the connecting rod 6, push blocks 7 are provided, and these push blocks 7 are connected to the sliding block 8 through a rotating connection. When the connecting rod 6 moves, the push blocks 7 at both ends will apply a thrust or a pull to the sliding block 8, thereby pushing or pulling the sliding block 8 to move. The sliding block 8 is slidingly connected to the hinge mold groove 9. Therefore, the movement of the sliding block 8 will drive the hinge mold groove 9 to open and close. At the same time, during the operation, the output shaft of the rotating motor 10 not only drives the rotating shaft 3 to rotate, but also synchronously drives the bevel gear 12 coaxially fixedly connected to the rotating shaft 3 to rotate. The rotation of the bevel gear 12 is then transmitted to the bevel gear 2 13 meshing with it, realizing a vertical transmission conversion. The rotation of the bevel gear 2 13 further drives the worm coaxially fixedly connected with it. 14 rotates, and the worm 14 meshes with one end of the worm wheel 18. This worm and worm wheel transmission mode not only realizes a large transmission ratio, but also has a self-locking function, that is, the worm wheel 18 will not rotate by itself when the worm 14 does not rotate. As the worm 14 rotates, the worm wheel 18 and the lead screw 16 coaxially fixedly connected to the worm wheel 18 also begin to rotate. The rotation of the lead screw 16 is the key to the lifting and lowering movement of the lifting limit block 17, because one end of the lifting limit block 17 is connected to the lead screw 16 by a thread. Therefore, when the hinge die groove 9 opens and closes, the lifting limit block 17 will perform corresponding lifting and lowering movements in the inner wall of the connecting frame 15 according to the rotation direction of the lead screw 16, and the upper limit block 17 will form a limiting effect on the die knife in the bending machine.

[0039] Finally, the operator can rotate the handle at one end of the worm 24, and this action directly drives the worm 24 to rotate. Since the worm 24 is meshed with the other end of the worm wheel 25, the rotation of the worm 24 will drive the worm wheel 25 to rotate synchronously. The rotation of the worm wheel 25 is the key to controlling the lifting of the threaded rod 23. Because the threaded rod 23 is coaxial with the worm wheel 25 and is connected by threads, as the worm wheel 25 rotates, the threaded rod 23 will move up and down in its axial direction. One end of the threaded rod 23 is fixedly connected to the top plate 22, so the top plate 22 will move with the rotation of the worm wheel 25. The top plate 22 moves synchronously with the lifting and lowering of the threaded rod 23. The operator can accurately control the height of the top plate 22 by adjusting the rotation direction and rotation amount of the worm gear 24 according to the thickness and shape of the metal sheet to be bent. When the top plate 22 is adjusted to a suitable position, the operator can place the metal sheet to be bent stably on the top plate 22. At this time, the top plate 22 cooperates with the opening and closing angle of the hinge die groove 9, providing stable and accurate support for subsequent bending operations, so that the bending machine can perform accurate and efficient bending processing on the metal sheet according to the preset bending parameters.
