It is a sheet forming machine designed for cold rolled sheet metal processing and is widely used in sheet bending processing in industries such as automobiles, aircraft manufacturing, light industry, shipbuilding, containers, elevators, and railway vehicles.

[0003] After searching, a Chinese patent with publication number CN213728704U discloses a CNC bending machine, including a bending machine body, the bending machine body includes a mounting table, a bending lower cutter die for abutting against a bending part is arranged on the mounting table, a bending groove is arranged on the bending lower cutter die, a bending cutter head is slidably connected to the bending machine body, a positioning assembly for positioning the bending part is arranged on the bending machine body, the bending machine body includes a front side surface of the bending machine, a mounting frame is arranged on the front side surface of the bending machine, the mounting frame includes a sliding seat slidably connected to the top of the mounting frame, a square plate is rotatably connected to the top of the sliding seat, the square plate is horizontally arranged and the sliding direction is perpendicular to the front side surface of the bending machine, and the top of the square plate is flush with the top of the lower bending cutter die.

[0004] The device enables workers to easily turn the bent parts when bending them, without having to lift the bent parts, thereby reducing the burden on the workers.

[0005] However, the device still has the following problems: the device carries the bending part together with the square plate and the lower bending die, and then adjusts the position of the bending part relative to the lower bending die by adjusting the position of the square plate, so as to facilitate the turning of the bending part. However, in actual use, when the bending knife head contacts the bending part, the two ends of the bending part will deform and warp. The device lacks a corresponding bending part limiting structure, which may easily lead to inconsistent corner lines of the bending part, and it is difficult to effectively improve the stability of the device in bending the plate.

[0017] 2. The numerically controlled bending machine for automatically adjusting the level of the slider is practical and efficient with a clever design. When the folding knife enters the working stroke from the rapid descent stroke, a pair of infrared transmitters emit infrared signals, which are received by a pair of infrared receivers. Then, the infrared receivers convert the infrared signals into electrical signals and transmit them to the controller.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment: As Figure 1 shown, a numerically controlled bending machine for automatically adjusting the level of the slider includes a bearing table 1 made of a high-strength alloy material to improve the overall structural strength and load-bearing capacity of the device. A hydraulic drive mechanism 2 is installed on one side of the top of the bearing table 1, and one end of the hydraulic drive mechanism 2 is fixedly connected to a folding knife 3. The hydraulic drive mechanism 2 plays a role in driving the folding knife 3 to move. It also includes a bending assembly and a leveling assembly arranged above the bearing table 1.

[0025] As Figure 3 shown in Figure 4 In one embodiment, in order to improve the bending stability of the device, the bending assembly includes a bearing plate 4 fixedly connected to the top edge of the bearing table 1 by welding. An installation plate 5 is fixedly connected to the top of the bearing table 1 near the bearing plate 4. The top of the installation plate 5 is fixedly connected to a bending lower die 6 adapted to the bending knife 3. Through the mutual cooperation between the hydraulic driving mechanism 2, the bending knife 3 and the bending lower die 6, the sheet material 13 is bent. A pair of first rotating shafts 7 are rotatably connected to both sides of the outer wall of the bearing table 1 through bearings. One side of the outer peripheral wall of each first rotating shaft 7 is fixedly connected to a limiting sleeve 8, where the first rotating shaft 7 serves to facilitate the rotation of the limiting sleeve 8. The inner peripheral walls of the limiting sleeves 8 are slidably connected to first limiting rods 9. The top of each first limiting rod 9 is fixedly connected to a connecting ring 10. One end of each connecting ring 10 is rotatably connected to a connecting rod 11. The sheet material 13 is placed on the top of the bending lower die 6. One end of each connecting rod 11 is fixedly connected to a sliding clamp 12 adapted to the sheet material 13. The inner wall of the sliding clamp 12 is coated with a lubricant. Through the mutual cooperation between the pair of sliding clamps 12, it is convenient to slide and limit the sheet material 13, avoiding the deflection of the sheet material 13 during the bending process and improving the stability of the device for bending the sheet material 13. A pair of second rotating shafts 14 are rotatably connected to both sides of the outer wall of the bearing table 1 away from the first rotating shafts 7. A second limiting rod 15 is fixedly connected between one side of the outer peripheral wall of each second rotating shaft 14 and the outer peripheral wall of the adjacent connecting rod 11. Through the mutual cooperation between the connecting rod 11, the second limiting rod 15 and the second rotating shaft 14, the sliding clamp 12 is further limited, improving the stability of the sliding clamp 12 for sliding and limiting the sheet material 13.

[0026] As Figure 2 shown in Figure 4As shown, in a certain embodiment, in order to improve the service life of the device, the leveling assembly includes a pair of infrared transmitters 17 installed on both sides of the outer wall of the folding cutter 3, and the axis of the emitting end of the infrared transmitter 17 is perpendicular to the axis of the outer wall of the folding cutter 3. The infrared transmitter 17 functions to emit infrared signals. One end of the outer peripheral wall of each of the second limiting rods 15 is fixedly connected to a fixing seat 16, and the top of each fixing seat 16 is fixedly connected to an infrared receiver 18 adapted to the infrared transmitter 17. The infrared receiver 18 functions to receive infrared signals. One side of the outer wall of the hydraulic driving mechanism 2 is installed with a controller 19, and the controller 19 is electrically connected to the infrared receiver 18 and the hydraulic driving mechanism 2. Through the mutual cooperation among the pair of infrared transmitters 17, the infrared receivers 18, and the controller 19, it is convenient to adjust the position of the piston in the hydraulic cylinder of the hydraulic driving mechanism 2, so that the bottom end of the folding cutter 3 is adjusted to a horizontal state, avoiding the folding cutter 3 from tilting and contacting the sheet material 13 and the bending lower die 6, thereby preventing the folding cutter 3 from deforming, and improving the service life and bending effect of the device.

[0027] Working principle: During use, first pass the sheet material 13 through a pair of sliding clamps 12, then place it on the top of the bearing plate 4 and the bending lower die 6, and then start the hydraulic driving mechanism 2 through the controller 19. The hydraulic driving mechanism 2 drives the folding cutter 3 to move downward. When the folding cutter 3 enters the working stroke from the rapid descent stroke, a pair of infrared transmitters 17 emit infrared signals, and the infrared signals are received by a pair of infrared receivers 18. Then the infrared receivers 18 convert the infrared signals into electrical signals and transmit them to the controller 19. If only one infrared receiver 18 receives the infrared signal, the controller 19 adjusts the position of the piston in the hydraulic cylinder of the hydraulic driving mechanism 2 to make the folding cutter 3 adjusted to a horizontal state, avoiding the folding cutter 3 from tilting and contacting the sheet material 13 and the bending lower die 6, thereby preventing the folding cutter 3 from deforming, and improving the service life and bending effect of the device. When the folding cutter 3 presses against the sheet material 13 downward, both ends of the sheet material 13 are bent along the angle of the bending lower die 6. Through the mutual cooperation among the pair of limiting sleeves 8, the first limiting rods 9, and the connecting ring 10, the pair of sliding clamps 12 slide to limit the sheet material 13, preventing the sheet material 13 from deflecting during bending. Then, through the mutual cooperation among the connecting rod 11, the second limiting rods 15, and the second rotating shaft 14, the sliding clamps 12 are further limited, improving the stability of the sliding clamps 12 in sliding and limiting the sheet material 13, and facilitating the improvement of the stability of the device in bending the sheet material 13.
