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

[0026] Please see Figures 1-7 This utility model discloses an adjustable integrated alignment device for a bending machine, including a machine frame 1 and a control panel 2 located on one side of the machine frame 1, as well as a pressure knife lifting assembly 3, a steel plate limiting assembly 4, and a distance measuring and alignment assembly 5, wherein:

[0027] An electrical control box 11 is fixed on one side of the frame 1, and an inlet 12 is provided in the middle of the frame 1.

[0028] Please refer to the attached Figure 6 The pressure plate lifting assembly 3 includes a pressure plate 31, which is fixed to the lifting plate 32 by screws. The upper mold 33 is fixedly connected below the pressure plate 31. The lower mold 34 is located directly below the upper mold 33 and is fixed at the inlet 12 of the machine frame 1. Specifically, the lifting plate 32 uses the pressure plate 31 to drive the upper mold 33 to squeeze the steel plate 6 and cooperate with the lower mold 34 to complete the bending.

[0029] The steel plate limiting assembly 4 includes a limiting pressure plate 41, a base plate 42 is provided directly below the limiting pressure plate 41, and a steel plate 6 is provided between the limiting pressure plate 41 and the base plate 42. The ranging and alignment assembly 5 includes a baffle plate 51, and a laser rangefinder 52 is provided on the opposite side of the baffle plate 51. The laser rangefinder 52 is electrically connected to the control panel 2. Specifically, the steel plate 6 is passed between the limiting pressure plate 41 and the base plate 42, and the steel plate 6 is pushed until its other end abuts against the baffle plate 51.

[0030] The base plate 42 is fixedly connected to the two ends of the integrated plate 43, and the other end of the integrated plate 43 is connected to the baffle plate 51. The top surface of the limiting pressure plate 41 is connected to the adjusting plate 45 through several springs 44. The two ends of the adjusting plate 45 are penetrated by the adjusting shaft 46 and rotated. The lower end of the adjusting shaft 46 penetrates the two ends of the base plate 42 and is screwed.

[0031] In this embodiment, the adjustment shafts 46 at both ends of the adjustment plate 45 are manually rotated. The adjustment shafts 46 rotate in the base plate 42 and interact with the base plate 42 through the threads to generate relative displacement, thereby driving the adjustment plate 45 to descend. The adjustment plate 45 drives the limiting pressure plate 41 through the spring 44 to press and fix the top surface of the steel plate 6. Example 2

[0032] Based on the above embodiment 1, please refer to the appendix. Figure 2 , Figure 3 , Figure 4 as well as Figure 5 The lifting plate 32 is fixed to one end of the rotating frame 35 by screws. The rotating frame 35 is rotatably fitted onto the rotating shaft 36. The other end of the rotating frame 35 is movably connected to the oil cylinder 37. The oil cylinder 37 is fixed to the bottom surface of the rear plate 38 by bolts. Specifically, the oil pump drives the oil cylinder 37 to move, which in turn drives one end of the rotating frame 35 to rotate around the rotating shaft 36. The other end of the rotating frame 35 moves down and drives the lifting plate 32 to press down.

[0033] The lower mold 34 is fixedly connected to a slide table 47 on one side, and the bottom surface of the base plate 42 is symmetrically provided with a slider 48, which is fitted and slidably engaged with the slide table 47.

[0034] The bottom surface of the baffle plate 51 is symmetrically equipped with a rotating wheel 53, and the rear plate 38 is fixed on the machine frame 1. One end of the rear plate 38 is fixedly connected to the rear slide table 54.

[0035] The rear slide table 54 has a straight rail 55 symmetrically arranged on its top surface, and the rotating wheel 53 is engaged with the straight rail 55 and moves in cooperation with it.

[0036] The top of the baffle plate 51 is provided with an adjusting plate 56, which is fitted and screwed into the screw shaft 57. The screw shaft 57 is mounted on the rotating motor 58.

[0037] In this embodiment, the laser rangefinder 52 first emits a laser pulse to measure the distance between the bent part of the steel plate 6 and the upper mold 33. Then, the rotating motor 58 is started for adjustment. The rotating motor 58 drives the spiral shaft 57 to rotate. The spiral shaft 57 acts on the adjusting plate 56 through the spiral force. The adjusting plate 56 drives the baffle plate 51 to move linearly in the straight rail 55, thereby driving the steel plate 6 to be adjusted to the preset bending part for bending.

[0038] The working principle and usage process of this utility model are as follows: First, the steel plate 6 is passed between the limiting pressure plate 41 and the bottom plate 42. The steel plate 6 is pushed until its other end abuts against the baffle plate 51. The adjusting shafts 46 at both ends of the adjusting plate 45 are manually rotated. The adjusting shafts 46 rotate in the bottom plate 42 and interact with the bottom plate 42 through the threads to generate relative displacement, thereby driving the adjusting plate 45 to descend. The adjusting plate 45 drives the limiting pressure plate 41 to press and fix the top surface of the steel plate 6 through the spring 44. This setting can fix steel plates 6 of different thicknesses and the downward pressure can be adjusted according to the deformation of the spring 44.

[0039] After the steel plate is fixed, the distance between the bent part of the steel plate and one end of the steel plate 6 can be input using the control panel 2. Then, the device is started. The laser rangefinder 52 first emits a laser pulse. The laser pulse is reflected after contacting the baffle plate 51 and returns to the rangefinder. The distance between the rangefinder 52 and the baffle plate 51 is accurately measured by the round-trip time. Then, the distance between the part of the steel plate 6 that needs to be bent and the upper mold 33 is calculated. Then, the rotating motor 58 is started for adjustment. The rotating motor 58 drives the spiral shaft 57 to rotate. The spiral shaft 57 and the adjusting plate 56 are relatively displaced by the spiral action. The adjusting plate 56 drives the baffle plate 51 to move in the straight rail 55 using the rotating wheel 53. The baffle plate 51 drives the base plate 42 to slide on the slide table 47 using the integrated plate 43. Then, the steel plate 6 is adjusted to the preset bending part for bending, realizing high-precision bending with integrated positioning and alignment.

[0040] Finally, the device starts the oil pump to drive the oil cylinder 37 to move, which in turn drives one end of the rotating frame 35 to rotate around the rotating shaft 36. The other end of the rotating frame 35 moves down and drives the lifting plate 32 to press down. The lifting plate 32 uses the pressure plate 31 to drive the upper mold 33 to squeeze the steel plate 6 and cooperate with the lower mold 34 to complete the bending. It is highly practical.
