Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 , this embodiment provides a technical solution: a fully automatic plate bending machine, comprising a bending shell 1 and a precise feeding mechanism 3;

[0023] Bending shell 1: Two symmetrically distributed electro-hydraulic push rods 2 6 are provided on the upper and lower sides of the right end thereof, and a bending seat 7 is provided between the telescopic ends of the two horizontally adjacent electro-hydraulic push rods 2 6. A PLC controller 2 is provided on the front side of the bending shell 1. The input end of the PLC controller 2 is electrically connected to the external power supply. The input ends of the electro-hydraulic push rods 2 6 are electrically connected to the output end of the PLC controller 2. The PLC controller 2 is bidirectionally electrically connected to the laser sensor 1 36. Two symmetrically distributed electro-hydraulic push rods 1 4 are provided on the upper side of the bending shell 1. The input ends of the electro-hydraulic push rods 1 4 are electrically connected to the output end of the PLC controller 2. The telescopic ends of the electro-hydraulic push rods 1 4 are provided with bending limit seats 5. Laser sensors 2 8 are provided on the upper and lower walls of the right end of the inner side of the bending shell 1. The laser sensors 2 8 are connected to the adjacent The bending seat 7 is installed in conjunction with the bending shell 1, and the second laser sensor 8 is bidirectionally electrically connected to the PLC controller 2. The front and rear walls of the right end of the bending shell 1 are provided with a discharge guide plate 11 through a plurality of evenly distributed telescopic columns 9 and springs 10. The springs 10 are movably connected to the outer ends of the adjacent telescopic columns 9. The front and rear ends of the bending seat 7 are provided with bevel chamfers 12, and the bevel chamfers 12 are installed in conjunction with the discharge guide plate 11. There are four telescopic columns 9 and springs 10 between the discharge guide plate 11 and the bending shell 1. When the plate is bent, the PLC controller 2 starts the electro-hydraulic push rod 1 4 so that its telescopic end drives the bending limit seat 5 to move vertically downward, thereby squeezing and fixing the upper left side of the bending part of the plate, and then the PLC controller 2 starts the electro-hydraulic push rod 2 6 so that its telescopic end drives The corresponding bending seat 7 is moved vertically to perform bending operations on the plate. The device adopts two sets of bending drive components to alternately perform upward and downward folding operations on the plate according to actual needs, effectively increasing the bending processing range of the plate by the device and being easy to use. At the same time, during the bending process of the plate by the device, the horizontal distance between the bending position of the plate and the bending seat 7 and the vertical distance between the middle position of the bending groove of the device and the initial position of the bending seat 7 are respectively entered into the PLC controller 2. The PLC controller 2 starts the laser sensor 2 8 to detect the vertical movement distance of the corresponding bending seat 7 through the same principle. The PLC controller 2 subtracts the vertical distance between the middle position of the bending groove of the device and the initial position of the bending seat 7 according to the vertical movement distance of the bending seat 7, and combines the plate bending The horizontal distance between the position and the bending seat 7 is used to obtain the bending angle of the plate by using trigonometric functions, so that the device can automatically adjust the bending angle of the plate. After the plate is bent, it moves out of the device along the inclined surface of the discharge guide plate 11. During the plate bending process, when the bending seat 7 contacts the discharge guide plate 11, the chamfers 12 at the front and rear ends of the bending seat 7 exert contact pressure on the edge of the discharge guide plate 11 close to the center of the device, so that the discharge guide plate 11 moves toward the end away from the center of the bending seat 7. The telescopic end of the telescopic column 9 and the spring 10 contract, so that the discharge guide plate 11 moves to avoid the bending seat 7. When the bending seat 7 is no longer in contact with the discharge guide plate 11, the compression force of the spring 10 resets the discharge guide plate 11.The device uses two sets of bending components and detection elements to accurately bend the bending part of the plate upward and downward, effectively improving the device's control range of the plate's bending angle;

[0024] Precision feeding mechanism 3: It includes a slide 31, a moving seat 32 and a laser sensor 36. The slide 31 is opened on the bottom wall of the left end of the inner side of the bending shell 1. The inner side of the slide 31 is slidably connected to the moving seat 32. The right end of the slide 31 is provided with a laser sensor 36. The laser sensor 36 is installed in conjunction with the moving seat 32. The precision feeding mechanism 3 also includes a rubber anti-skid pad 33. The rubber anti-skid pad 33 is arranged on the upper side of the moving seat 32. The precision feeding mechanism 3 also includes a reciprocating screw 34 and a drive motor 35. The reciprocating screw 34 is connected to the inside of the slide 31 through a bearing, and the reciprocating screw 34 is threadedly connected to the moving seat 32. A driving motor 35 is provided on the left side of the bending shell 1. The input end of the driving motor 35 is electrically connected to the output end of the PLC controller 2. The output shaft of the driving motor 35 is fixedly connected to the left end of the reciprocating screw 34. When the plate is subjected to CNC automatic bending, the plate is first placed on the left end of the inner side of the bending shell 1, and the lower side of the plate contacts the upper side of the moving seat 32. Then the PLC controller 2 starts the driving The motor 35 drives its output shaft to rotate the reciprocating screw 34, and the reciprocating screw 34 is connected by a thread so that the moving seat 32 drives the plate to the right along the slide groove 31 for bending and conveying. The right end of the plate passes through the bending groove and enters the right end of the device. The rubber anti-slip pad 33 increases the contact friction to avoid relative sliding between the moving seat 32 and the plate. At the same time, the PLC controller 2 starts the laser sensor 36. The laser sensor 36 emits a light signal to the left side of the moving seat 32 and reflects it to the initial position. The right movement distance of the moving seat 32 is detected by the propagation time and speed of the light signal, and the detection result is transmitted to the PLC controller 2 in the form of an electrical signal. The PLC controller 2 opens and closes the drive motor 35 according to the measurement result, and can accurately control the bending length of the plate according to the bending requirement of the plate. The device can bend and convey the plate accurately through the detection element and the transmission element, so that the device can arbitrarily adjust the bending position of the plate according to actual needs.

[0025] The working principle of a fully automatic plate bending machine provided by the present invention is as follows: when performing CNC automatic bending on a plate, the plate is first placed on the left end of the inner side of the bending shell 1, and the lower side of the plate contacts the upper side of the movable seat 32. Then the PLC controller 2 starts the drive motor 35 so that its output shaft drives the reciprocating screw 34 to rotate. The reciprocating screw 34 is connected by a thread so that the movable seat 32 drives the plate to the right along the slide groove 31 for bending and conveying. The right end of the plate passes through the bending groove and enters the right end of the device. The rubber anti-slip pad 33 avoids relative sliding between the movable seat 32 and the plate by increasing the contact friction. At the same time, the PLC controller 2 starts the laser sensor 36, and the laser sensor 36 emits a light signal. The light is irradiated to the left side of the movable seat 32 and reflected to the initial position. The right movement distance of the movable seat 32 is detected by the propagation time and speed of the light signal, and the detection result is transmitted to the PLC controller 2 in the form of an electrical signal. The PLC controller 2 adjusts the opening and closing of the drive motor 35 according to the measurement result, and can accurately control the bending length of the plate according to the bending requirements of the plate. When the plate is bent, the PLC controller 2 starts the electro-hydraulic push rod 1 4 so that its telescopic end drives the bending limit seat 5 to move vertically downward, thereby squeezing and fixing the upper left side of the bending part of the plate, and then the PLC controller 2 starts the electro-hydraulic push rod 2 6 so that its telescopic end drives the corresponding bending seat 7 to move vertically, thereby bending the plate. The device adopts two sets of bending drive components to alternately fold the plate up and down according to actual needs, effectively increasing the bending processing range of the plate by the device and being easy to use. At the same time, during the bending process of the plate by the device, the horizontal distance between the bending position of the plate and the bending seat 7 and the vertical distance between the middle position of the bending groove of the device and the initial position of the bending seat 7 are respectively recorded in the PLC controller 2, and the PLC controller 2 starts the laser sensor 28 to detect the vertical movement distance of the corresponding bending seat 7 through the same principle. The PLC controller 2 subtracts the vertical distance between the middle position of the bending groove of the device and the initial position of the bending seat 7 according to the vertical movement distance of the bending seat 7, and combines the horizontal distance between the bending position of the plate and the bending seat 7 to detect the vertical movement distance of the bending seat 7. The plate is bent and moved out of the device along the inclined surface of the discharge guide plate 11. During the plate bending process, when the bending seat 7 contacts the discharge guide plate 11, the chamfers 12 at the front and rear ends of the bending seat 7 exert contact pressure on the edge of the discharge guide plate 11 close to the center of the device, so that the discharge guide plate 11 moves toward the end away from the center of the bending seat 7. The telescopic end of the telescopic column 9 and the spring 10 contract, so that the discharge guide plate 11 moves to avoid the bending seat 7. When the bending seat 7 is no longer in contact with the discharge guide plate 11, the compression force of the spring 10 resets the discharge guide plate 11.
