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 scope of protection of the present utility model.
[0018] Please see Figures 1-4As shown, a cable tray elbow forming device includes a base 1, a control panel 2 mounted on the base 1, a placement groove 3 and a forming groove 4 on the base 1, in which a cable tray 5 is placed. Two sets of fixing brackets 6 are symmetrically mounted on the base 1, and a lead screw 7 is rotatably mounted between the two sets of fixing brackets 6. The threads on the lead screw 7 are symmetrically opposite in direction. A stepper motor 8 is mounted on one of the fixing brackets 6 via a machine base, and the output shaft of the stepper motor 8 is connected to the lead screw 7. A guide rod 9 is fixedly mounted between the two sets of fixing brackets 6. Clamping plates 10 are symmetrically sleeved on the lead screw 7 and the guide rod 9. The clamping plates 10 are connected by screws... The guide rod 7 slides in cooperation with the lead screw 7. A fixing block 11 is welded on the clamping plate 10. An infrared generator 12 and an infrared receiver 13 are installed on one of the clamping plates 10. The infrared generator 12, infrared receiver 13 and stepper motor 8 are synchronously connected to the control panel 2. A limiting plate 14 is sleeved on the lead screw 7 and guide rod 9. The limiting plate 14 slides in cooperation with the lead screw 7 and guide rod 9. A spring 15 is installed between the limiting plate 14 and the base 1. The spring 15 is sleeved around the guide rod 9. A support frame 16 is welded to the rear wall of the base 1. A hydraulic cylinder 17 is installed on the top plate of the support frame 16. A hydraulic cylinder 17 is connected to... A hydraulic rod 18 is fixedly connected to a connecting plate 19 on its bottom side. A moving groove 20 is provided on the side wall of the support frame 16, and a moving block 21 is assembled in the moving groove 20. The moving block 21 is fixedly connected to the side wall of the connecting plate 19, and a pressure block 22 is installed on the moving block 21. During operation, the existing forming equipment is prone to displacement of the cable tray 5 during the bending process. Due to the inability to stably position the cable tray 5, the stability of the cable tray 5 is poor, affecting the accuracy of the bending of the cable tray 5. By placing the cable tray 5 in the placement groove 3, under the action of the spring 15, the two sets of limiting plates 14 It is attached to both ends of the cable tray 5; the infrared generator 12 is controlled by the control panel 2 to emit an infrared beam. The infrared beam is reflected after encountering the limiting plate 14. The reflected infrared beam is received by the infrared receiver 13. The infrared receiver 13 obtains the time interval between the infrared beam being emitted and received, and sends a signal to the control panel 2. The control panel 2 calculates the distance value between the clamping plate 10 and the limiting plate 14 based on the propagation speed of the infrared beam in the air and the time interval between the infrared beam being emitted and received. The control panel 2 compares the distance value with the threshold value, which is the thickness value of the fixing block 11.
[0019] When the spacing value is inconsistent with the threshold, the control panel 2 controls the stepper motor 8 to operate. The stepper motor 8 drives the lead screw 7 to rotate, and the lead screw 7 drives the two sets of clamping plates 10 on it to move synchronously relative to each other. The clamping plates 10 move horizontally towards the limiting plate 14 until the spacing value is consistent with the threshold. At this time, the control panel 2 controls the stepper motor 8 to stop operating. At this time, the fixing block 11 is in contact with the limiting plate 14. Since the two sets of clamping plates 10 are always symmetrically arranged, the cable tray 5 is in a centered state.
[0020] The fixing block 11 on the clamping plate 10 is in contact with the limiting plate 14, which realizes the limiting of the limiting plate 14. The limiting plate 14 is in contact with the cable tray 5, which realizes the limiting of the cable tray 5. At this time, the cable tray 5 is in a stable state.
[0021] The hydraulic cylinder 17 operates, the hydraulic rod 18 drives the connecting plate 19 to move vertically downward, the connecting plate 19 drives the moving block 21 to move vertically downward, the moving block 21 drives the pressing block 22 to move vertically downward, and the pressing block 22 presses the cable tray 5, thus achieving the bending treatment of the cable tray 5.
[0022] During the bending process of the cable tray 5, under the action of the spring 15, the two sets of limiting plates 14 are always in contact with both ends of the cable tray 5. The two sets of limiting plates 14 continuously move towards the center. At the same time, the infrared generator 12 continuously emits infrared beams. The control panel 2 continuously acquires the spacing value. The control panel 2 controls the stepper motor 8 to operate, so that the clamping plates 10 move synchronously relative to each other, so that the fixing block 11 is in contact with the limiting plate 14. That is, when the cable tray 5 is bent, its two ends are always clamped and fixed, which prevents the cable tray 5 from shifting and helps to improve the stability of the cable tray 5.
[0023] Working principle: In the existing forming equipment, the cable tray 5 is prone to displacement during the bending process. Because the cable tray 5 cannot be stably positioned, its stability is poor, affecting the accuracy of the cable tray 5 bend forming. By placing the cable tray 5 in the placement groove 3, the two sets of limiting plates 14 are in contact with both ends of the cable tray 5 under the action of the spring 15. The control panel 2 controls the infrared generator 12 to emit an infrared beam. The infrared beam is reflected after encountering the limiting plates 14, and the reflected infrared beam is received by the infrared receiver 13. The infrared receiver 13 then receives the infrared beam emitted from the receiver. The system calculates the distance between the clamping plate 10 and the limiting plate 14 based on the speed of infrared light propagation in the air and the time interval between the emission and reception of the infrared light. The control panel 2 then compares the distance value with a threshold value, which is the thickness of the fixed block 11. When the distance value does not match the threshold, the control panel 2 controls the stepper motor 8 to operate. The stepper motor 8 drives the lead screw 7 to rotate, which in turn drives the two sets of clamping plates 10 to move synchronously relative to each other. The clamping plates 10 move horizontally towards the limiting plate 14 until the distance value matches the threshold. Control panel 2 stops stepper motor 8, at which point fixing block 11 is in contact with limit plate 14; since the two sets of clamping plates 10 are always symmetrically arranged, the cable tray 5 is in a centered state; fixing block 11 on clamping plate 10 is in contact with limit plate 14, thus limiting limit plate 14, and limit plate 14 is in contact with cable tray 5, thus limiting cable tray 5, at which point cable tray 5 is in a stable state; through the operation of hydraulic cylinder 17, hydraulic rod 18 drives connecting plate 19 to move vertically downward, connecting plate 19 drives moving block 21 to move vertically downward, moving block 21 drives pressing block 22 to move vertically downward, pressing block 22... The cable tray 5 is pressed down, which achieves the bending process of the cable tray 5. During the bending process of the cable tray 5, under the action of the spring 15, the two sets of limiting plates 14 are always in contact with both ends of the cable tray 5. The two sets of limiting plates 14 continuously move towards the center. At the same time, the infrared generator 12 continuously emits infrared beams. The control panel 2 continuously acquires the spacing value. The control panel 2 controls the stepper motor 8 to operate, so that the clamping plates 10 move synchronously relative to each other, so that the fixing block 11 is in contact with the limiting plate 14. That is, when the cable tray 5 is bent, its two ends are always clamped and fixed, which prevents the cable tray 5 from shifting and helps to improve the stability of the cable tray 5.
